Specific embodiment
The present invention is described in more detail with reference to the accompanying drawings and detailed description.
From the figure 3, it may be seen that a kind of mining liquid CO 2 reducing temperature for preventing fire extinguishing system, is mainly stored up by liquid carbon dioxide low temperature
Tank, boosting vaporizer regulator control system and flat board mine car 5 are constituted, and the liquid carbon dioxide low-temperature storage tank includes inner bag 1 and outer courage 2,
Liquid carbon dioxide low-temperature storage tank and boosting vaporizer regulator control system form connection, and liquid by supercharging device and feeding device
State carbon dioxide low-temperature storage tank and boosting vaporizer regulator control system are positioned over the upper end of flat board mine car 5.
As shown in Figure 1, in the present invention, it is preferred to liquid carbon dioxide low-temperature storage tank inner bag by pipeline be connected with into
Liquid valve V1, residual liquid discharge valve V2, tapping valve V3, supercharging return-air valve V4, liquid level gauge, pressure gauge valve V5, pressure charging valve V6, vaporizer row
Liquid valve V7, full of indication valve V9, discharge opeing service valve V10, gas valve V11, safety valve V12, vacuum valve V13 and exhaust, emptying
Valve V14, while being additionally provided with a rupture disk V8 in any side of outer courage 2.
As shown in Figure 2, in the present invention, it is preferred to boosting vaporizer regulator control system include assemble pipe 6, boost port 3, feed liquor
Mouth 4 and leakage fluid dram 7, boost port 3, inlet 5 are connected to the left end for assembling pipe 6, and are connected with the formation of inner bag 1, and leakage fluid dram 7 connects
In the right-hand member for assembling pipe 6, and a case 8 is arranged with pipe 6 is assembled.
What the system of the present invention was specifically so used：
1st, the tapping valve V3 of opening residual-gas valve V2 and tank car about three minutes, cool down infusion tube and exclude in flexible pipe after air,
Turn off residual-gas valve（V2).
2nd, crack liquid feed valve V1, gas emitting valve V11, pressure gauge, juice level indicator valve V5 and liquid are full of indication valve V9, depending on feelings
Condition connects storage tank gas phase mouth, makes tank inner pressure record initial pressure value P and liquid level gauge reading L more than 1.0MPa..
When the 3rd, starting to fill tank, gas atmospheric valve V11 and liquid are full of the indication valve V9 very little to be controlled, and treat storage tank precooling
Afterwards, liquid feed valve V1, the aperture of gas valve V11 can be gradually increased, by 2 tons of a filling quantity to calculate, record fill the tank time and
Fill tank speed.
4th, when there is liquid from full of the ejection of indication valve V9, show that storage tank has been filled with, storage tank liquid feed valve V1, groove are closed immediately
Car tapping valve, gas atmospheric valve V11, residual liquid discharge valve V2 is opened full of indication valve V9, release transfusion overpressure and Liquid Residue
After body, infusion tube and the soft road of gas phase are pulled down, fill end.（Generally pressure is 1.8MPa or so）.
5th, opening liquid level gauge, pressure gauge valve V5 makes it come into operation.
6th, discharge opeing high-pressure rubber pipe and supercharging return-air high-pressure rubber pipe accordingly connect storage tank and boosting vaporizer respectively
Good, vaporizer discharge opeing sebific duct is connected firmly.
7th, crack liquid tapping valve V3, pressure charging valve V6, return-air valve V7 are to time of one precooling of boosting vaporizer and certain
Pressure, can gradually open then after a while big tapping valve V3, close pressure charging valve V6, vaporizer purge valve V7 accelerate drain age velocity, when
Tank inner pressure drops to below 1.0MPa, when not meeting discharge opeing pressure requirements, it is necessary to gives storage tank supercharging, is first shut off vaporization
Device purge valve V7, slowly opens pressure charging valve（V6) allow liquid to enter boosting vaporizer, supercharging return-air valve V4 is then turned on, to storage tank
Supercharging.It is noted that observation pressure gauge, liquid level gauge, each valve, joint etc. whether there is race, emit, leak phenomenon in pressurization, work as supercharging
When reaching 1.8MPa and meeting discharge opeing pressure requirements, close supercharging return-air valve V4, pressure charging valve V6 and stop supercharging, open vaporizer row pressure
Valve V7 continues discharge opeing.
8th, in discharge opeing process, must at any time note observing liquid level gauge, pressure gauge, each valve and pipeline, prevent prominent
Heat condition occurs.The cryogenic liquid in storage tank is discharged must not completely totally during discharge opeing, it is necessary to retain it is certain it is balance of next time
Fill and prepare, usual liquid level gauge indicating value about exists（1.0-1.5KPa) when, close tapping valve（V3）, prevent dry ice or enter empty
Gas.
9th, standard-sized sheet vaporizer purge valve V7 valves, after releasing discharge opeing high-pressure rubber pipe and the pressure in vaporizer, pull down discharge opeing high
Moulding pipe, connects next tank car or discharge opeing terminates.
Generally speaking, mining liquid CO 2 reducing temperature for preventing fire extinguishing system capacity of the invention is big, entrained titanium dioxide
Carbon is more, and the fire extinguishing being relatively adapted to when larger down-hole space catches fire, the system carries pressure charging system, the carbon dioxide that moment is sprayed
Intensity is big, and fire extinguishing is rapid；Simultaneously the simple structure of the system, transports also more convenient.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the know-why without departing from the present invention, some improvement and modification can also be made, these improve and become
Type also should be regarded as protection scope of the present invention.
