Background technology
The kind of fire extinguisher is a lot, can be divided into by its move mode: portable and cart type; Can be divided into by the power resources that drive extinguishing chemical: gas bomb formula, pressure storage type, chemical equation; Can be divided into again by the extinguishing chemical that fills: foam, dry powder, alkyl halide, carbon dioxide, soda acid, clear water etc.
The utility model content
The purpose of this utility model is to provide a kind of carbon dioxide hydrate slurry extinguishing device.
Its technical solution is:
A kind of carbon dioxide hydrate slurry extinguishing device, it comprises carbon dioxide hydrate slurry generator, the top of generator is communicated with the gas cylinder that carbon dioxide is provided by pipeline, water or the additive aqueous solution are housed in generator, the bottom of generator is communicated with storage slurry device by pipeline, storage slurry device is communicated with fire extinguisher by pipeline, the carbon dioxide hydrate slurry that the generator internal reaction generates is delivered in storage slurry device through pipeline and stores, and the carbon dioxide hydrate slurry that stores in storage slurry device is delivered to fire extinguisher by pipeline.
Preferably, on carbon dioxide hydrate slurry generator, agitator is installed.
Preferably, described agitator is mechanical agitator or magnetic stirring apparatus.
Preferably, starch equal setting pressure sensor, temperature sensor and safety valve on device in generator and storage.
Preferably, control valve is installed on pipeline.
Useful technique effect of the present utility model is:
1, the utility model adopts the carbon dioxide hydrate of self-control good fluidity to starch as firing-fighting medium, and the carbon dioxide of gaseous state is not only arranged in fire extinguishing procedure, also has the hydrate ejection of pulpous state; The carbon dioxide and the flame contact-making surface that discharge on the one hand are large, can play isolated air purpose; Be an endothermic process when hydrate slurry decomposes on the other hand, can reduce the temperature of comburant, make it be difficult to burning, comprehensive above two aspects can play good fire extinguishing effect.Compare with existing extinguishing device, the utlity model has environment-friendly high-efficiency, cheap advantage.

3, this device also can be applied to preventing and extinguishing fire of coal mine, and firing-fighting medium can be taken from the carbon dioxide in coal bed gas or mine ventilation gas.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is structural principle schematic diagram of the present utility model;
Fig. 2 is carbon dioxide hydrate phase equilibrium line figure.
In figure: 1-carbon dioxide hydrate slurry generator, 2-gas cylinder, 3-mechanical agitator, 4-storage slurry device, 5-fire extinguisher, 6-pressure sensor, 7-temperature sensor, 8-safety valve, 9-control valve.
The specific embodiment
In conjunction with Fig. 1, a kind of carbon dioxide hydrate slurry extinguishing device, it comprises carbon dioxide hydrate slurry generator 1, the top of generator 1 is communicated with the gas cylinder 2 that carbon dioxide is provided by pipeline, water or the additive aqueous solution are housed in generator 1, mechanical agitator 3 is installed on generator 1, be used for adding fast response, the bottom of generator 1 is communicated with storage slurry device 4 by pipeline, and storage slurry device 4 is communicated with fire extinguisher 5 by pipeline.The carbon dioxide hydrate slurry that generator 1 internal reaction generates is delivered in storage slurry device 4 through pipeline and stores, and the carbon dioxide hydrate slurry that stores in storage slurry device 4 is delivered to fire extinguisher 5 by pipeline.Starch equal setting pressure sensor 6, temperature sensor 7 and safety valve 8 on device 4 in generator 1 and storage.Control valve 9 is installed on pipeline.
