Description
Technical field
The utility model relates to a kind of eruption device, especially relates to the eruption device that is applicable to pulvis.
Background technology
In fire-fighting and agriculture spraying field, need to use pulvis eruption device at present.Such as in a single day chlorine leakage takes place; In time use chlorine arresting agent that chlorine leakage point and range of scatter are sprayed, make arresting agent and chlorine generation neutralization reaction, reduce the harm of chlorine the person, environment; Be that what to relate at present that the chlorine industry generally adopts also is the most effective emergency method; Also be same situation aspect fire extinguishing, except make fire-fight by water, also need a lot of fire extinguishers that use pulvis.The chlorine arresting agent device of present domestic use mainly contains three kinds: the one, and portable chlorine arresting device; The 2nd, cart type chlorine arresting device; The 3rd, the chlorine arresting car.
The primary structure of the pulvis fire extinguisher of these three kinds devices and common usefulness is formed: pulvis and pressure gas, pulvis playpipe are arranged in cylindrical shell, the cylindrical shell; Operation principle is after in cylindrical shell, loading pulvis; Use gas pressurized in advance, utilize during use in the cylindrical shell from pressing pulvis to be sprayed, pressure reduces gradually; During internal and external pressure balance, pulvis can not spray again.All there is following shortcoming in these devices: the one, and the pulvis storage is limited; Because its barrel designs become movably and need in advance in pressurising, so that the cylindrical shell volume can not be accomplished is very big, and its volume can not all be used for loading pulvis; Stay a large amount of space charged pressure gas; So it is dosage is maximum catches the car that disappears and also can only deposit about 0.6 ton of pulvis,, then powerless like chlorine leakage or fire greatly; The 2nd, have the mini-plant effect limited, main equipment then needs the above operation of two people, operation easier is big, and is closely to operate, operating personnel need be equipped with special personal protective equipment, dress respirator and biochemical defence suit, personnel at the scene the time of staying limited; The 3rd, pulvis sprays inhomogeneous.These devices all are inner presseds, and pressure of the inside of a bottle reduces gradually, and jet velocity is first big after small, and jet length back far away earlier is near, has not slowly just reached eject request, so do not have continuity.The 4th, pulvis utilizes insufficient, and when the interior pressure of these devices was consistent with external environment condition pressure, pulvis just can not spray again.Also there are above problem in the hand fire extinguisher of filling powder extinguishing agent or transportable fire extinguisher and fire-fighting vehicle at present.
The utility model content
Disappear and the deficiency of fire distinguisher, fire-fighting vehicle in order to overcome existing catching, the utility model provides a kind of pulvis eruption device, can not only load the more pulvis of volume, and can realize automatic, long-range, even, continuous eruption.
The pulvis eruption device that the utility model provides; Comprise powder dispenser, injector and connecting line, powder dispenser is under shed, and is said to lower opening installation injector; Injector is connected with the eruption pipeline with the air pressure pipeline; On the air pressure pipeline pressure-control valve is installed, draws the balance pipeline on the said air pressure pipeline, said balance pipeline inserts the powder dispenser upper opening.Like this, pulvis is stored in the basin, protects with pressure gas (preferably nitrogen) pressurising; Need the time spent, the operating pressure control valve, pulvis gets into injector through the effect of gravity; In injector, pulvis evenly mixes with pressure gas from pipe network, and pulvis suspends in air-flow; Under the drive of pressure gas, arrive the eruption point, realize the eruption function of various ways.With original apparatus in comparison, the one, the cylindrical shell of filling pulvis and pressurising strength has been divided into the powder dispenser and outside high pressure gas of filling pulvis, and gas pressure can the situation that pressure reduces not occur after spraying a period of time like this; The 2nd, be provided with injector separately, be connected respectively with gas with pulvis by injector, maintenance and replacing so more easily, injector also can be according to size and its size of pulvis characteristics design and the parameter of powder dispenser.
Preferably, between powder dispenser and injector, density control valve is installed, between said balance pipeline and the powder dispenser air pressure balance valve is installed.Density control valve can be adjusted pulvis and the mixed concentration height of pressure gas, according to circumstances needs in use, and decision injection concentration avoids excessive concentration to form waste and concentration is crossed low poor effect.Draw the balance pipeline on the air pressure pipeline between said pressure-control valve and the injector; Described air pressure pipeline is connected with high-pressure nitrogen bottle or external high pressure tracheae, and described eruption pipeline front end is equipped with atomizer, the balance pipeline give powder dispenser inside applied with injector in same air pressure; Powder dispenser just need not shift to an earlier date stowing pressure gas like this; As long as open balance control valve, powder dispenser just has same pressure, like this pulvis just fully can be under the effect of gravity the entering injector.If there is not same pressure to exist in the powder dispenser, then after opening density control valve, the high pressure gas in the injector is known from experience elder generation and in powder dispenser, is charged into, and makes powder dispenser pulvis when just beginning to open the control valve switch can't get into injector, influences result of use.Described density control valve and described air pressure balance valve are autocontrol valve.The information that autocontrol valve can import into through the outside or according to the pressure condition in the detected pipeline of working pressure checkout gear realizes the control to valve.Such as: electronic control, Electromagnetic Control, pneumatic control or dynamic flow balance valve.With valve control pulvis concentration and air pressure size, when using automatic valve, can also realize control and far distance controlled automatically; The eruption pipeline can connect many, and front end can connect a plurality of nozzles, can fix removable.
Beneficial effect
The utility model can be obtained following technique effect:
The one, increased the pulvis injector newly, make pulvis can utilize the gravity effect to get into injector, pulvis fully mixes with power gas in injector, and utilizes the effect of valve to adjust dosage and concentration arbitrarily;
The 2nd, changed the power source that pulvis sprays, made outside metastable source of the gas into by the pressure gas that fills in advance in the container, it is uniform and stable that pulvis is sprayed, and pulvis can make full use of;
The 3rd, the pulvis basin can fixedly mount; Be positioned at the injector top; Pulvis utilizes gravity to get into injector, so just can store the more pulvis of volume, during use regardless of what have used; Can under the situation of occlusion pressure strength, conveniently dose after the use, the service condition and life-span of container all is being beneficial to;
The 4th, the pressure in the powder dispenser can be provided by balance control valve control in use, does not need filling gases at high pressure in jar at ordinary times, has prolonged the service life of jar.
