The gas-producing explosion suppressor comprises a gas-producing chamber and a damping chamber communicated with the gas-producing chamber, as well as a medicament chamber and a nozzle; an explosion sheet is arranged between the damping chamber and the medicament chamber; a sealing film is arranged between the medicament chamber and the nozzle; the gas-producing chamber is arranged in the damping chamber and is a cylinder with two closed ends; and the circumference of the cylinder is provided with an air hole which is communicated with the damping chamber.
Description
Technical field
The utility model relates to fire extinguishing, the explosion arrestment equipment that safety guarantee is used, particularly a kind of air-generating explosion suppressor.
Background technology
The blast of fuel gas or dust is the take place frequently one of the main reasons of accident of operation places such as industry, storage, tunnel, pipeline conveying, petrochemical industry always, datonation-inhibitionly become a kind of method that can effectively control blast, the effective means that prevents to explode and spread to other unit or place.
Explosion suppressor is a datonation-inhibition technology important safety equipment commonly used.When fuel gas or dust explosion take place when, sensor will burn or explosive flame is transformed into the signal of telecommunication and is sent to control device, control device just sends instruction after calculating, analyzing, the interior gas-forming agent of explosion suppressor that ignites makes it to carry out rapidly chemical reaction, discharge a large amount of gases, driving Explosion suppressant sprays from nozzle, form the Explosion suppressant cloud and mist of high concentration fast, fully contact with flame front, absorb the energy of flame, stop pyric chain, make fray-out of flame, in being full of the restricted clearance of explosion gas, continue to propagate thereby stop flame front.
The gas production of air-generating explosion suppressor is to be determined by the composition of dress gas-forming agent and quality, existing explosion suppressor spray pattern generally adopts gas to produce the spray pattern that the back directly drives medicament, gas produces speed and gas production and has determined the explosion suppressor effect of dusting, thereby has limited the datonation-inhibition ability of explosion suppressor.Now also there is improved explosion suppressor to adopt gas to produce and drives the frame mode that medicament sprays again after a less volume cavity cushions transition, the fire extinguishing of this explosion suppressor, explosion arrestment effect improve, but can't adjust because of its driving gas pressure, speed are subjected to cushioning the cavity structure restriction, and cause the Explosion suppressant cloud and mist concentration that sprays, the needs that scope still can't satisfy different work condition environments.
The utility model content
The purpose of this utility model is the problem that the existing air-generating explosion suppressor driving gas pressure of solution, speed can't be adjusted, a kind of improved explosion suppressor is provided, make datonation-inhibition effect not limited by gasification speed, and the release pressure of driving gas can be regulated, the Explosion suppressant cloud and mist and the close diffusing effect that can farthest form high concentration fast are more even, distribution is wider, and fire extinguishing, explosion arrestment requirement to adapt to different work condition environments have wider range of application and field.
The purpose of this utility model can realize by following technical proposals:
The air-generating explosion suppressor comprises aerogenesis chamber and the cushion chamber that communicates with it, and medicament chamber, nozzle, is provided with rupture disk between cushion chamber and the medicament chamber, is provided with seal membrane between medicament chamber and the nozzle.
In order to control driving gas pressure, speed better, the pressure parameter of described rupture disk can be matched according to the different application operating mode.
Structure is more specifically, and described aerogenesis chamber is installed in cushion chamber inside, is the cylindrical tube of closed at both ends, and the cylindrical shell circumference is provided with the passage that communicates with cushion chamber.
Described cushion chamber and the cylindrical shell of medicament chamber for docking, both removably are docking together by first flange.
The periphery of described rupture disk is fitted on first flange.
Described medicament chamber and nozzle removably are docking together by second flange.
The periphery of described seal membrane is fitted on second flange.
The indoor gas-forming agent that is equipped with of described aerogenesis, the aerogenesis chamber also is provided with initiating device.
Described medicament is equipped with Explosion suppressant in the chamber.
The utility model adopts said structure, between cushion chamber and medicament chamber, rupture disk is set, rupture disk by apolegamy different pressures parameter, after the gaseous products that can make the indoor formation of aerogenesis breaks through rupture disk with the gas rate of release of needs and turbulivity, enter in the medicament chamber, thereby realize by regulating the release pressure of driving gas, make datonation-inhibition effect not limited by gasification speed, can fully improve the close diffusing uniformity that Explosion suppressant sprays cloud and mist, gas discharges the propagation of the back formation more effective termination flame front of impulse wave energy in being full of the restricted clearance of explosion gas simultaneously.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: the 1st, aerogenesis chamber, the 2nd, passage, the 3rd, cushion chamber, the 4th, rupture disk, the 5th, medicament chamber, the 6th, seal membrane, the 7th, nozzle.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, the air-generating explosion suppressor comprises aerogenesis chamber 1, cushion chamber 3, medicament chamber 5 and nozzle 7, and cushion chamber 3 and medicament chamber 5 removably are docking together by first flange, and medicament chamber 5 and nozzle 7 removably are docking together by second flange.
Aerogenesis chamber 1 is installed in the inside of cushion chamber 3, is the cylindrical tube of closed at both ends, and the cylindrical shell circumference is provided with the passage 2 that communicates with cushion chamber 3.
Be pressed with rupture disk 4 on first flange between cushion chamber 3 and the medicament chamber 5, the periphery of rupture disk 4 is fitted on first flange, and can break behind its middle part pressurized.Among the embodiment, rupture disk 4 has the characteristic that pressure parameter can be regulated.
Be pressed with seal membrane 6 on second flange between medicament chamber 5 and the nozzle 7, the periphery of seal membrane 6 is fitted on second flange, and can break behind its middle part pressurized.
Cushion chamber 3 is a hollow container, is used to collect adjust the gas that gas-forming agent produces behind chemical reaction, and by the rupture disk of apolegamy different pressures parameter, can the adjustments of gas release pressure, thus satisfy the sprinkling needs of varying environment.
