Abstract

The present invention relates to a fire suppression system and method in which an extinguishing agent is automatically discharged from a limited source of supply of the wet chemical extinguishing agent for rapid extinguishment of the fire, followed by water application to the locus of the fire from an unlimited source of supply of water. The subsequent automatic application of water provides rapid cooling of the hot burning material below its reflash temperature. The present hybrid system exploits the best fire suppression properties of both agents against fires i.e. the wet chemical extinguishing agent provides rapid flame extinguishment and water provides rapid cooling following extinguishment. The present hybrid system is significantly more robust (fire test variables are less critical to its fire suppression performance) than current water or wet chemical agent systems. <IMAGE>

Description

The present invention relates to a fire suppression or hold-down system and a method for deleting Fire up by spreading a fire extinguishing composition a fire with subsequent use of water. The sy stem can use a special extinguishing composition, wel che a unique mixture of at least two salts comprises, the mixture a single minimum Shows melting point.

In fire fighting, fire is classified into four general classes, namely class A, class B, class C and class D. Splits.

Class A fires are those that are ordinary flammable Material, such as paper, wood, etc. can relate to and through Extinguish and cool with large amounts of water or solder solutions that contain a large percentage of water, to be deleted.

Class B fires are those which contain shortening, oils, fats, easily flammable liquids, etc. concern. With this Type of fire is the use of water in general ineffective because the contact of water with the hot oil causes a strong splash without extinguishing the flames and the hot burning oil or fat spread the fire can. This type of fire is the most difficult to solve due to the low self-ignition points of Shortening, oils and fats, which are in the range of about 360 ° C. up to 380 ° C. Furthermore, it makes the presence of  extremely flammable materials in large quantities extremely important to put out the fire as soon as possible and also bring the temperature down to flare up again to prevent what's happening at a lower temperature of 337 ° C occurs.

Class C fires concern electrical equipment or Ge councils. Therefore, the electrically conductive property of Extinguishing material is an essential aspect. For this Purpose was found that dry fire extinguishing agents in space common are more useful. It was also found that the Fire extinguishing agent useful for class B fire Class C fires are useful.

Class D fires relate to flammable metals and are used special dry powders deleted.

Many different fire extinguishing compositions and fire extinguishing systems using such compositions has been the developed and are available on the market. The how the flare up or the self-ignition of hot shortening, However, oils or greases in Class B fires remain first problem. This is especially true when such fires large commercial facilities such as restaurants, cafeterias s, exhibition halls, etc. The potential danger sol The fire in these types of facilities is good knows.

Prior art systems for extinguishing fires with cooking equipment or appliances in a kitchen use a water rain or a sprinkler system. If such systems are used, the deletion of Fat, oil, shortening or fat fires up to 6 minutes last. The splash water can cause a violent flame cause. In such systems, the fat, oil, Shortening or liquid fat fire in the end due to the cooling effect of the water used on the hot oil or fat  deleted. A sprinkler fire protection system for Deductions over cooking units are used in U.S. Patent 4,356,870 shown. Another system that automatically creates a strong Flow of extinguishing agent over critical areas of a grease or releasing oil fire is open in U.S. Patent 3,584,688 beard.

Various fire protection systems from the state of the art for restaurants use protected wet chemicals to ag gressive fire in fume cupboards, pipes and cooking utensils suppress or hold down. This wet agense are typically aqueous solutions of organic Salts that are specially formulated to burn deeply Fat fire in two different phases too to press. During the first phase, the agent or agent directly on the fat fire for quick extinguishing (about 5 Se customers) of the flames through a chemical reaction splashes. In the second phase, wetting is continued the danger spot to both the hot fat to cool down, as well as to connect to it protective foam blanket on top of the hot fat The foam blanket protects the hot fat from backing ignition or a flare by expelling air is closed until the fat either under its back or Autoignition temperature cools down or the foam blanket from the heat of the hot fat breaks down underneath, or both. The water content in the wet agent is one effective coolant (a positive feature), but will canceled by the insulating effect of the foam blanket, which delays the heat release of the hot fat (a negative feature). If water alone on a fat Fire is sprayed, it has turned out to be a very weak one Extinguishing media proved to be an effective coolant, however set that it is for a longer period (on average about 6 to 9 minutes). It actually becomes water alone don't extinguish the flames until the hot fat is under his back or Autoignition temperature has cooled.  

It is an object of the present invention to provide a Fire suppression system ready to be deployed quickly Put down the flames by using a wet one Chemical provides and also cooling and securing the hot fats, oils, shortening, liquid fat or light flammable liquids (fuels) through the wide supplies an unlimited amount of water.

It is another object of the present invention Fire suppression system to provide the better Cover over a grease or oil fire and that easily installed in existing kitchen equipment that can.

The present invention relates to fire suppression system and a method in which an extinguishing agent automa table from a limited supply source of wet chemistry Kalien extinguishing agent is discharged, after which water on site of fire from an unlimited source of water supply is used. The following automatic ver Application of water provides a rapid cooling of the hot burning material under its reignition or Flash point temperature. The protective foam blanket, which normally produced by an extinguishing agent alone, can be negated by splash water dilution to the outstanding cooling effects of water compared to the hot to maximize burning material, such as a fat or oil. However, the present hybrid system takes advantage of the best Un suppressive properties of both agents against fire from, d. H. the wet chemical extinguishing agent provides a quick Flame extinguishing and water provide rapid cooling the deletion. The present hybrid system is essential stronger or less sensitive (the fire test variables are less critical to its fire suppression performance) than current water or wet chemical systems.  

In the dry riser embodiment of the present The system automatically becomes an extinguishing agent in liquid form table by a fire suppression system given. The fire suppression system includes a device automatic fire detection device for automatic actuation of the suppression system, ei NEN storage container for an extinguishing agent, a distribution pipe for the extinguishing agent and the water and nozzles for spraying the wet chemical extinguishing agent and subsequently towards the fire. Operation of the system is such that after the end of the discharge of the extinguishing agent an automatic switching device the following on water automatically through the same manifold line and the same spray nozzles of the system as for who uses the extinguishing agent on the fire that, delivers.

The automatic switching device for switching from Extinguishing agent flow to water flow is controlled by an automatic Valve executed. The automatic switching valve is removed neither operated by gas or hydraulic pressure, dependent of which of the three possible valves with the dry riser system is used, as in the following Ab will be described, the details of the section lying invention with reference to the figures poses.

In a dry riser embodiment of the invention is a liquid extinguishing agent in the distribution pipeline is picked up and released to the fire by a system ben, which is a fire detection facility, an on Direction for automatic operation, distribution pipes for the extinguishing agent and the water and spray nozzles for the end surround the fire extinguishing agent and water sums up. At the end of the discharge of the liquid extinguishing agent the subsequent use of water occurs automatically automatic shut-off or check valve  through the same distributor pipe and the same spray nozzle a.

The extinguishing agent can also be in solid, because in liquid, Form stored in a main or primary storage facility and can be caused by the inflow of water into the Pri March storage facility to be solved. The inflow of what sers is automatically fireproof by a device position and a device for automatic operation drove. The flow of the extinguishing agent dissolved in water follows through the manifold and spray nozzles, where the flow of water after the dissolved extinguishing agent solution is used up, is continued.

The extinguishing agent can also be in solid form within many Storage facilities are available, which are directly in front of everyone Spray nozzle are arranged, and can flow through be released from water. The inflow of water will automatically by a fire detection device and actuated a device for automatic operation. The flow of the extinguishing agent dissolved in water takes place through the spray nozzles, the flow of water after the dissolved saline solution is used, is continued.

Fig. 6 is a detail of a nozzle usable in the present system.

A dry riser embodiment of the present invention is shown in FIG. 1. A solution of the fire extinguishing composition 1 receiving tank 3 is connected via pipes 7 with device nozzles 6 , distributor channel nozzles 8 and pipe nozzles 9 . A valve assembly 4 (details are shown in Figures 4A and 4B) mounted on the tank 3 controls the sequential release of the fire extinguishing composition solution and water. When a fire is detected by a detector device, a seal in a gas cartridge 2 is broken and gas is released from the gas cartridge 2 at high pressure. The high pressure gas simultaneously presses a spring loaded piston against the water inlet valve (not shown) to prevent water from being discharged and to cause the solution in the tank to be discharged through nozzles 6 , 8 and 9 . When the gas pressure is reduced to a particular pressure, such as 3.10 bar (45 psi), the spring loaded piston of the valve assembly moves to an open position so water can flow to the tank 3 and out of the nozzles.

The embodiment shown in Fig. 2 is a wet line system. Prior to operating in the acquisition system of the storage tank 20 and the distribution duct pipe 21 with wet means or Naßagens be filled. The tank 20 and the distribution channel pipeline 21 are under pressure by compressed gas at the top of the tank. The discharge nozzle tiles 22 , 23 , 24 are closed. If one or more of the heat actuated nozzle valves 22 , 23 , 24 in response to heat from an aggressive fire opens or opens, wet agent is automatically removed from the tank 20 and the manifold 21 through the open nozzles 27 , 28 , 29 the compressed gas in the tank 20 is expelled. When the compressed gas pressure falls below the water pressure at the water inlet check valve 26 , water will automatically flow through the manifold 21 and the same open nozzles 27 , 28 , 29 until the water supply is turned off by hand. Only those nozzles 27 , 28 , 29 that open in response to heat from aggressive fire will automatically discharge agent and water to the burning hazard.

FIGS. 3A, 3B and 3C show cross-sectional views ei ner automatic valve special equipment of a dry pipe system. The storage tank 31 is filled with a wet chemical or wet agent 32 and is under atmospheric pressure. A valve 33 has a gas inlet port 34 which is connected to a gas pressure regulator (not shown) on the Ansul Autman release assembly (not shown). The gas regulating device is connected to a propellant gas cartridge which contains nitrogen or carbon dioxide propellant gas under high pressure. The Ven tilwassereinlaß 35 is connected to a public or urban water supply or restaurant wet sprinkler system and is under static water pressure. The double piston assembly 36 is determined in the closed position by the spring-loaded return pin 37 , so that the static water pressure will not move the double piston assembly 36 . The valve discharge port 38 is tubed with many discharge nozzles (not shown), each of which is directed to a potential fire hazard.

When an aggressive fire is detected, the spring loaded release assembly 39 (not shown) automatically acts to pierce the seal of the propellant cartridge (not shown), thereby releasing high pressure propellant through the pressure regulator (not shown) where the Pressure is reduced to a lower operating pressure and therefore to the valve 33rd The propellant gas fulfills two functions in the tank structure 31 . First, it rotates or shifts the double piston assembly 36 toward the water inlet port 35 to release the spring-loaded return pin 37 which enters a recess in the valve body as shown in Fig. 3B. Second, the propellant gas is brought through valve 33 to the top of the tank, where it pressurizes the wet agent 32 to drive it down the tank, up to the receiver pipe 41 , through the valve discharge port 38 and out of the discharge nozzles (not shown). During the Nassagenensaustrag the gas pressure on the piston 42 and the liquid pressure from the Naßagens on the other piston 43 hold the piston assembly 36 in the position unlocked against the static water pressure.

When the wet agent is driven out of the tank and the gas pressure drops to a critical level, the net force on the double piston assembly will reverse (the force by which the water pressure will open will be greater than the force to continue closing under decreasing pressure ) and the static water pressure will rotate the piston assembly 36 against the gas inlet 34 , the Wassereinlaßöff opening 35 is opened to the discharge outlet opening, wherein water can flow from the same discharge pipeline to the discharge nozzles. The water will flow until it is turned off manually or manually below the valve. The check ball 44 prevents water from entering the tank.

The present valve is operated mechanically by Pa tron pressure is used to pneumatically close the valve press and start the flow of the extinguishing agent.

In the event of a fire, the cartridge pressure for opening 34 is released. The pressure piston releases the locking / reset pin 37 . This pin is spring loaded to pull away from the piston when the lock is released. Pressure, which is carried through the inlet 34 , is also directly connected to the head space of the tank, where the agent is expelled by the gas from the cartridge. If the tank pressure drops after the wet chemical is expelled, the holding force acting on the piston area decreases, as a result of which the water pressure can move the valve into a "water open" position. Then water flows through the distribution pipeline and is applied to the extinguished hazard area, which cools the fat or the cooking surface and prevents reignition or a re-flare.

FIGS. 4A and 4B show another automatic valve special equipment Trockensteigleitung- a fire protection system. The tank 50 is filled with a wet chemical lie 51 under atmospheric pressure. The water inlet port 52 of the valve assembly 53 is piped to a water supply source. The valve 53 is closed and is under static water pressure. The connected water line (not shown) includes a check valve (not shown) to prevent backflow when the system is initially started. The high pressure gas inlet 54 of valve 53 is piped to the high pressure side of the gas pressure regulator (not shown) on the spring loaded release assembly (not shown) and is at atmospheric pressure until the fire protection system is started. The high pressure line (not shown) includes a check valve (not shown) to trap high pressure gas in the line when the system is started. As an optional feature, the high pressure gas line may include an outlet port so that the high pressure gas is released slowly so that the water pressure can automatically close the valve after the water has been discharged for a minimum of time to minimize flooding. The low-pressure gas inlet opening 55 on the pipe assembly is piped to the low-pressure side of the same gas pressure regulator and is also under atmospheric pressure until the system is started. The gas pressure regulator (not shown) is piped to a gas cartridge (not shown), a small pressure vessel that contains a certain amount of nitrogen or carbon dioxide propellant gas under high pressure. The tank discharge port 56 on the receiver tube assembly 57 is piped with many discharge nozzles (not shown), each of which is directed to a potential fire hazard.

When an aggressive fire is detected by the fire protection system, the spring loaded release assembly (not shown) automatically acts to pierce the propellant cartridge seal, releasing high pressure gas at both the high pressure gas inlet of valve 54 and the pressure regulator where the high gas pressure is reduced to a lower operating pressure. The high pressure gas opens the valve 53 to what server supply by turning the piston 59 and 60 Stangenauf construction to the water inlet 52 against the force of the spring 61 and the static water pressure. As soon as the piston rod assembly 59 , 60 is open, the captured high pressure gas will keep it open until the gas pressure is released manually after the fire event, when the system is refilled and adjusted again. The low pressure gas from the regulator enters the head of the tank to expel the wet agent 51 from the tank 50 through the tank outlet port 56 , discharge tubing (not shown), and discharge nozzles (not shown). As soon as the low pressure gas flows, the regulating device will feed the low pressure gas into the tank at a constant pressure until the falling pressure of the gas in the fixed volume cartridge falls below the preset outlet pressure of the regulating device, at which time the gas pressure from the regulating device will also decrease will decrease over time.

Although the valve was originally opened by the high pressure gas, water will not flow into the tank 50 until the water pressure from the water supply exceeds the decreasing gas pressure of the low pressure gas in the head of the tank 50 , at which time water will automatically flow through the tank 50 , Discharge pipeline and discharge nozzles will begin to flow. The water will continue to flow until it is manually turned off below the valve after the fire event has ended.

Fig. 5 shows a third automatic valve special equipment of the dry riser system. The automatic, remote-operated valve 70 can be arranged in the agent distributor pipe (not shown) of the present fire protection system between the wet storage tank (not shown) and the discharge nozzles (not shown). The agent inlet port 71 at the top of the valve is piped to the discharge connection on the wet agent storage tank and is at atmospheric pressure until the system is discharged. The discharge opening 72 on the valve is piped with many discharge nozzles (not shown), each of which is directed to a potential fire hazard point. The water inlet opening 76 at the bottom of the valve is piped to a water supply source and is under static water pressure. Piston 74 includes two circumferential O-rings (not shown) to seal against hydraulic pressure from either side. The piston 74 is fixed in the closed position by a spring-loaded return pin assembly 75 to resist the static water pressure. Since the reset pin 75 is hooked on the piston, it can not withdraw under spring load (to be computationally th page scroll) is rotated until the piston during the Betriebszy klus down.

If an aggressive fire is detected by the system, the spring-loaded release structure (not shown) automatically acts to pierce the seal of the LPG cartridge (not shown), which causes LPG (nitrogen, carbon dioxide or air) to be subjected to high pressure by the pressure regulator ( not shown) is released where the pressure is reduced to a lower operating pressure. From the regulator, the gas is fed into the interior of the agent storage tank (not shown), where it drives the wet agent out of the tank, through the normally open openings in the automatic valve 70 and out of the discharge nozzles (not shown). The hydraulic pressure of the wet flow through the automatic valve 70 will rotate the plunger 74 downward against the water pressure to release the reset pin 75 , which then moves under its spring force into the wall of the valve body. While the Nassagens flows through the valve under maximum regulated gas pressure, the piston 74 will remain in the closed position, since the hydraulic pressure of the Nassagen against the larger diameter of the piston 74, the water pressure exceeds the smaller diameter of the piston.

When the wet from the tank is expelled and the gas pressure from the cartridge drops to a critical level, the net force of the piston will reverse (the force to open by water pressure will be greater than the force to close the piston to continue under decreasing wet pressure) and the piston is turned upward to close the agent inlet opening 71 and open the water outlet opening 76 to the discharge outlet, where water can flow to the discharge nozzles until it is manually turned off.

A particular system nozzle that can be used with the present invention is shown in FIG. 6.

The nozzle 80 has a swivel 81 so that it can be rotated 30 ° in any direction from the center line of the body.

The nozzle 80 also includes a vane 83 which spins the liquid which is exhausted from the tip 82 to stabilize the exit spray cone. The inner bore of the nozzle tip is designed to a configuration that controls both the critical flow and spray angle of the discharge. In the case of the new device nozzle, the nominal flow rate will be 6.4 l / min (1.7 gallons of water per minute) at 5.48 bar (80 psi) nozzle pressure. The spray angle (including the angle of the cone of what is discharged) will be nominally 60 °.

The flow speeds and spray angles for the nozzles, which the fume hoods and piping over the unit protect, are based on the environmental conditions against the nozzle setting and based on the well-known Er requirement of fire extinguishing agent and water at the nozzle posi tion set up. The device nozzle has a built-in Swivel on, whereas the nozzles for the hood and don't need to turn the pipes.

The present invention relates to a fire protection system, automatically the successive discharge of a fire extinguishing composition and water actuated. The fire protection system includes new valve assemblies. The valve structure can be on top of the fire extinguishing composition The tank may be attached or the valve assembly may become entangled  far from the tank. Preferred valve structures or compilations are described above.

A preferred fire extinguishing composition, which in the pending U.S. patent application filed with the serial number . . . titled "A combination a new, a eutectic salt mixture and water ver applying fire extinguishing composition and method their use for extinguishing fire "is disclosed and this preferred composition is particularly advantageous in the operation of the present fire suppression system. The co-pending application is referenced expressly included here.

The preferred new fire extinguishing composition, which is a unique mixture of at least two salts I and II wherein salt I is selected from the group consisting of a carbonate or bicarbonate of sodium or potassium stands, and salt II is selected from the group consisting of a chloride, sulfate or tartrate salt of sodium or Ka lium exists, and the mixture of I and II shows one individual minimum melting temperature range at DSC. The Ge Mix is particularly effective when combined with additional water is used. The property of this unique mixture is analogous to that of a eutecti cum where a mixture of two or more metals or  Salt show a minimum melting point. I is a salt with the following properties: it dissociates under Bil formation of carbon dioxide when heated and it is in the area from about 25 g to 150 g / 100 mil water soluble. II is a Salt or a mixture that, if in a special Ratio is mixed with I, a single minimum Delivers melting temperature range. It was found that by adding a small amount of 10 mol% to 20 mol% II to I the mixture a single minimum Shows melting temperature range that is lower than that from I alone or II alone. Also lies with this tempe rature the heat capacity of the mixture, its ability Absorb heat, at a maximum, at a value of is greater than the heat capacity of the individual components The only minimum melting temperature range is through Using differential scanning calorimetry (DSC) be tunable.

It has been found that when the unique mixture is considered Extinguishing media, followed by water, is used Combination extremely effective for extinguishing class B fire is concerned with oils or fats and backfire prevention of self-ignition.
