Abstract
The invention provides a method for operating a fire extinguishing assembly. The method involves using inert gas provided by an operational process of a factory or a manufacturer to be protected instead of the extinguishing gas obtained extraneously. The inert gas is to be supplied to a gas supplying guide pipe (3) and then to a valve area (6) by the gas supplying guide pipe (3). Each valve area (6) is equipped for discharging the extinguishing gas respectively to a certain fire extinguishing area. A control gas guide pipe (7) is branched from the gas supplying guide pipe (3). The pressure of the inert gas is reduced in the control gas guide pipe (7). The gas after pressure reduction is supplied to a control unit (10) for controlling a corresponding valve area (6).
Description
Technical field
The present invention relates to a kind of method of operating of fire extinguishing system, this fire extinguishing system is used for using with gas extinguishing agent, wherein, can be used as extinguishing chemical because of the inert gas that operation process obtains.The invention still further relates to a kind of system that is used to implement described method.
Background technology
In the fire extinguishing system of routine, liquid CO
2As extinguishing chemical.In order to store CO
2, this system need be equipped with the bigger gas container of cooling device.Such system has sizable space requirement, and this space requirement will cause the increase of operating cost again.
As being used to avoid for the method than the needs of atmospheric container, also the inert gas that can obtain easily at each factory or manufactory scene is as extinguishing chemical.For example, in steel plant, a large amount of nitrogen can be obtained, thereby their part extinguishing chemical can be used as.In addition, in the chemical plant, inert gas can be obtained so that partly as extinguishing chemical.
When the inert gas that is used for operation process is concentrated to the needed degree of fire extinguishing, may be harmful.For this reason, employer's organization, the chamber of commerce or other legal person regulation: when in fire extinguishing system, using inert gas, start this system and must be accompanied by technical equipment and the siren that startup is used to postpone gas release.
The object of the present invention is to provide the possibility that when avoiding putting out a fire operation, the people is produced using gases extinguishing chemical under the dangerous situation, though simultaneously by utilizing very simple device reliable and that permit through official to meet known regulation about personnel protection.
Summary of the invention
Realize above-mentioned purpose by following means: a part of extinguishing chemical diverges out and is supplied to zone valve via the control system that is equipped with existing element from operation process, and these extinguishing chemicals are by reducing to control air pressure through pressure-reducing valve.
By said method, realized inert gas used or that produce in use fork from operation process operation process that come out, factory.This gas is used as control gas with its air pressure that reduces, thereby can use existing control element through permission, is subjected to dangerous desired protection thereby guarantee prevents the people.
Term " existing element " should be understood to following meaning: utilized known standard component, for example utilized CO
2Fire extinguishing system.Therefore, when putting into practice method of the present invention, control element can not cause any expense about new structural design and required new permission.
These standard components are laid in by the manufacturer of fire extinguishing system, and can at any time install, and therefore also are convenient to the maintenance of the interchangeability and the system of control element.
Description of drawings
Illustrate in more detail in the following description of the present invention all with necessary disclosure, the disclosure comprises its optimal mode, make those of ordinary skills can implement the present invention, following description is with reference to accompanying drawing, wherein, unique Fig. 1 is the schematic diagram that the method according to this invention is come operated system.
The specific embodiment
By gas on-site conduit 1, the inert gas that can obtain from operation process will be supplied to supply conduit 3 and zone valve 6 via stop valve 2, described zone valve 6 is arranged in the fire extinguishing conduit 4 that is provided with fire-suppressant gas nozzle 5, and described nozzle is included in the fire extinguishing system 22.Via control gas conduit 7, part inert gas will branch away to be used as control gas from described supply conduit 3, reduce to required control air pressure by pressure-reducing valve 8 then, and further be provided to control system 9, control system 9 comprises control module 10 and central fire alarm receiving element 11, central authorities' fire alarm receiving element 11 is provided with one or more fire detectors 12, and each in the described detector 12 is connected in control corresponding line 23.Described control module 10 comprises the time control valve 15 of gushing out, is designed for delay is opened under the help of stepper motor control valve 16, cock 17 and stop valve 18, all these element arranged in series.From described central fire alarm receiving element 11, control line 13 leads to the described time control valve 15 of gushing out, and another control line 14 leads to described control valve 16.In being subjected to the zone of flameproof protection, also arranged O
2 Concentration measurement equipment 19, O
2 Concentration measurement equipment 19 is connected in the control line 20 that leads to central fire alarm receiving element 11.This makes it possible to by utilizing described O
2Concentration measurement equipment is monitored the oxygen content (O in the fire extinguishing zone
2), this oxygen content (O
2) because of the fire extinguishing procedure of introducing nitrogen reduces, and under the situation of the oxygen content that surpasses expectation, start fire extinguishing back process.Therefore, can avoid breaking out once more fire.(schematically illustrated) another control gas conduit 21 is connected in described control gas conduit 7, and described another control gas conduit 21 can be directed to another possible fire extinguishing zone.
Just in case breaking out of fire, described fire detector 12 will be to the generation of central fire alarm receiving element 11 report fire, and central fire alarm receiving element 11 will correspondingly start described time control valve 15 and the described control valve 16 gushed out.The termination time of stepper motor set for make use up in the time of setting before, the people that just is in the protected field can have an opportunity to withdraw from a room, fire-suppressant gas will begin to pour in the room after this.After control valve 16 has been opened, the actuating time control valve 15 of gushing out, control gas will flow to the control inlet of zone valve 6 from conduit 7, and this control inlet will be opened now, and feasible fire-suppressant gas from supply conduit 3 spreads to whole scene of fire via fire-suppressant gas nozzle 5.Above-mentioned cock 17 is provided for---must stop the situation about gushing out of fire-suppressant gas if necessary---.
Though reference specific description embodiment of the present invention is described and explained the present invention, the present invention should not be limited to these illustrated embodiment.Persons skilled in the art can be recognized to make under situation about not breaking away from as the true scope of the present invention that limited by following claim and change and revise.Therefore, the present invention should comprise all such changes and modifications and the equivalent way thereof that falls in the claims scope.
