The movable type liquid carbon dioxide fire preventing and extinguishing device for the mine is provided with a low-temperature carbon dioxide liquid storage tank, an explosion-proof operation box and an operating valve of the low-temperature carbon dioxide liquid storage tank, wherein the operating valve of the low-temperature carbon dioxide liquid storage tank is installed in the explosion-proof operation box, and a tank body of the low-temperature carbon dioxide liquid storage tank is provided with a stainless-steel inner layer, a steel outer layer and a middle layer made of a heat insulating material.
Description
Technical field
The utility model relates to the anti-fire extinguishing field of Conflagration Caused by Coal Self-ignition, is specifically related to the anti-extinguishing device of a kind of mining mobile liquid carbon dioxide.
Background technology
The carbon-dioxide fire engine technology has that extinguishing ability is strong, speed is fast, the scope of application extensively, characteristics such as etching apparatus and being widely used not.Carbon dioxide has inhibition method and gasholder fire fighting method in the using method aspect the anti-fire extinguishing at present.Chemical method is to utilize chemical reaction to prepare carbon dioxide to be used for fire extinguishing, and the cost of this method production carbon dioxide is higher, and along with the development of carbon dioxide storage technology, the application of this method is dwindled just gradually.The gas storage pot process is divided into low pressure gasholder method and high-pressure gas pot process again.Low pressure gasholder method gas-storing capacity is little, can't satisfy fire extinguishing needs in a big way; Existing high-pressure carbon dioxide fire-extinguishing apparatus is furnished with devices such as evaporimeter, refrigeration unit, and its volume is big, can only use on ground, is not suitable for using in mine laneway.
Summary of the invention
Problem to be solved in the utility model provides a kind of anti-extinguishing device of portable liquid carbon dioxide that can be transported in the underworkings.
The technical scheme that addresses the above problem is: the anti-extinguishing device of the portable liquid carbon dioxide that is provided comprises the operation valve of low-temperature carbon dioxide liquid storage vessel, explosive operation case and low-temperature carbon dioxide liquid storage vessel, wherein the operation valve of low-temperature carbon dioxide liquid storage vessel is installed in the explosive operation case, and the cell body of low-temperature carbon dioxide liquid storage vessel has the intermediate layer that stainless steel internal layer, steel skin and heat insulating material constitute.Storage tank charges into liquid carbon dioxide on ground, transports to the down-hole then and implements fire extinguishing.
For the ease of the carrying and the operation, above-mentioned low-temperature carbon dioxide liquid storage vessel is fixed in the framework, its preferred mode be by saddle fixation on this framework.
For safer, be provided with protective screening at the top of said frame, this protective screening is positioned at the top of low-temperature carbon dioxide liquid storage vessel.
Compare with existing high-pressure carbon dioxide fire-extinguishing apparatus, the utility model need not refrigeration unit, evaporimeter and heating component, and its volume is little, and compact conformation is simple to operate, is convenient to the tunnel and transports.Experiment shows that the carbon dioxide speed of putting of releasing of the present utility model is 3～4T/h, and release rate reaches more than 95%.
Description of drawings
Fig. 1 is the structure chart of an embodiment of the utility model.
Fig. 2 is the valve system figure that is used for Fig. 1 embodiment.
The specific embodiment
As shown in Figure 1: the body of low-temperature carbon dioxide liquid storage vessel 1 has the intermediate layer 4 that stainless steel internal layer 2, steel outer 3 and heat insulating material constitute, and wherein the closed tank of stainless steel internal layer 2 formation is welded by straight tube 21, left end socket 22 and right end socket 23; Existing heat insulating material is adopted in intermediate layer 4, such as polyurethane, asbestos etc.; It also is to be welded by straight tube and left and right sides end socket that steel outer 3 forms shell.Framework 5 is cuboid frameworks that are made of angle steel.Low-temperature carbon dioxide liquid storage vessel 1 is fixed in the framework 5 by the saddle on the framework 6, explosive operation case 7 also is fixed in the framework 5, it is positioned at the right side of low-temperature carbon dioxide liquid storage vessel 1, and framework 5 tops are provided with the protection steel mesh, is used to prevent to fall thing damage storage tank 1.
Concrete enforcement is: low-temperature carbon dioxide liquid storage vessel 1 is after ground has filled, be transported to the place to use, down-hole by mining flat car, be connected to fire district by pipeline again, utilize self pressure for vaporization of liquid carbon dioxide, liquid carbon dioxide directly is pressed into the fire district, implements fire extinguishing.
Fig. 2 has provided the valve control system of low-temperature carbon dioxide liquid storage vessel 1 shown in Figure 1.
Each operation valve in the explosive operation case has: valve V1 on the content gauge, content gauge equalizing valve V2, valve V3 under the content gauge, safety valve V7 and V7 ', emptying control valve V9, atmospheric valve V12, residual liquid discharge valve V13, survey full valve V14, gas turnover valve V15, liquid turnover valve V16, safety vent valve V18 and V19, tapping valve V22, outlet valve V24.
Be example description operation process with storage tank 1 topping up attitude carbon dioxide now.Topping up attitude carbon dioxide front opening air inlet body turnover valve V15, keeping a jar internal pressure is 2.6MPa.Close tapping valve V22, open liquid turnover valve V16, atmospheric valve V12 and safety vent valve V18, V19, close emptying control valve V9, residual liquid discharge valve V13, gas turnover valve V15, close gas emitting valve V24, open and survey full valve V14, connect infusion tube, begin to charge.The jar internal pressure is regulated by outlet valve V24, when liquid sprays from expiring side valve V14, shows that fullness rate reaches requirement, and promptly closing liquid passes in and out valve V16.Read tank body internal pressure and liquid level by pressure meter PI and content gauge LI.Tank body has 2 groups of safety valve V7 and V7 '; Safety valve V7 and V7 ' open when the basin internal pressure surpasses safe pressure, the beginning exhaust decompression.After filling completely, be transported near the fire district, connect transfer pipeline, open tapping valve V22, directly put out a fire with liquid carbon dioxide.
The on off state of each valve is as shown in the table under other state.
