Abstract
The utility model discloses a compressed air-based mine refuge chamber air supply system, comprising a downhole air compressing channel 1, an air cylinder set 11, and a pressure-reducing valve 13. The air cylinder set 11 is connected with the pressure-reducing valve 13. Particularly, the compressed air-based mine refuge chamber air supply system further comprises a compressed air supercharger 4. A low-pressure air inlet of the compressed air supercharger 4 is connected with the downhole air compressing channel while a high-pressure air outlet is connected with the air cylinder set. The compressed air-based mine refuge chamber air supply system further comprises an oil-water separator, a low-pressure valve, an overflow valve, a compression gauge and a throttle valve. When the mine refuge chamber is in standby, compressed air in the downhole air compressing channel 1 is supercharged through the compressed air supercharger 4 and the supercharged compressed air is led into the air cylinder set 11 for storage. When the mine refuge chamber is in use, the compressed air in air cylinder 11 is decompressed by the pressure-reducing valve 13 and then led into the mine refuge chamber for people to breathe. The compressed air-based mine refuge chamber air supply system is characterized in that the system is economical in energy consumption and small in maintenance amount, and the system makes air inside the refuge chamber fresh.
Description
Technical field
The utility model relates to mine urgent danger prevention field, is specifically related to a kind of based on compressed-air actuated mine refuge underground chamber air supply system.
Background technology
Mine refuge underground chamber inside is an airtight space, after mine has an accident, and the down-hole blowing-out that often has a power failure.So mine refuge underground chamber must be equipped with oxygen system, satisfy the personnel's that take refuge besoin de respirer.Existing mine refuge underground chamber oxygen system is mainly the compressed oxygen oxygen supply, and the shortcoming of the method is the problem that compressed oxygen cylinder has slow leakage, and the long necessary oxygen cylinder oxygen of giving of time one increase maintenance.
Existing mine refuge underground chamber air supply system also exists an incomplete place can only replenish the used up oxygen of human body exactly, and can not replenish fresh air in a large number, causes air dirt in the refuge chamber, and personnel can't stand.
It is thus clear that existing mine refuge underground chamber air supply system also exists needs to improve perfect place.
Summary of the invention
The purpose of the utility model is the weak point to the prior art existence; Propose a kind of based on compressed-air actuated mine refuge underground chamber air supply system; Utilization is dispersed throughout the air line in each corner, down-hole, the air in the pipeline is stored in advance, as the source of the gas to the mine refuge underground chamber air feed; It is little to reach when system reserve maintenance, keeps the fresh purpose of air in the refuge chamber in use.
For achieving the above object, the utility model has been taked following technical scheme:
The utility model is a kind of based on compressed-air actuated mine refuge underground chamber air supply system; Comprise down-hole air line, gas cylinder group, reducing valve; Described gas cylinder group is connected with reducing valve; Particularly also comprise the compressed air booster, and the low-pressure admission mouth of compressed air booster is connected with the down-hole air line, the high pressure gas outlet is connected with the gas cylinder group.When mine refuge underground chamber was subsequent use, the compressed air in the air line of down-hole was through the supercharging of compressed air booster, and the compressed air after the supercharging gets into the gas cylinder group and stores; During use, the compressed air in the gas cylinder gets into mine refuge underground chamber, the usefulness of confession personnel breathing after the reducing valve decompression.
Above-mentioned is a kind of based on compressed-air actuated mine refuge underground chamber air supply system; Also have oil water separator, low pressure valve, overflow valve, pressure meter, choke valve, the said equipment is connected with pipeline by the order of low pressure valve, oil water separator, compressed air booster, overflow valve, pressure meter, gas cylinder group, reducing valve, choke valve.
Above-mentioned is a kind of based on compressed-air actuated mine refuge underground chamber air supply system, and the air pressure in the gas cylinder is 20～48MPa.
The utility model design based on compressed-air actuated mine refuge underground chamber air supply system have maintenance little, easy to use, make the fresh characteristics of air in the refuge chamber.
Description of drawings
Fig. 1 is the structural representation of a most preferred embodiment of the utility model.
The specific embodiment
Referring to Fig. 1; Based on compressed-air actuated mine refuge underground chamber air supply system; Comprise down-hole air line 1, gas cylinder group 11, reducing valve 13, described gas cylinder group 11 is connected with reducing valve 13, particularly also comprises compressed air booster 4; And the low-pressure admission mouth of compressed air booster 4 is connected with the down-hole air line, and the high pressure gas outlet is connected with the gas cylinder group.When mine refuge underground chamber was subsequent use, the compressed air in the down-hole air line 1 was through 4 superchargings of compressed air booster, and the compressed air after the supercharging gets into gas cylinder group 11 and stores; During use, the compressed air in the gas cylinder group 11 gets into mine refuge underground chamber, the usefulness of confession personnel breathing after reducing valve 13 decompressions.
Above-mentioned is a kind of based on compressed-air actuated mine refuge underground chamber air supply system, also comprises oil water separator and 3 low pressure valves 2, and it places between down-hole air line 1 and the compressed air booster 4.
Above-mentioned is a kind of based on compressed-air actuated mine refuge underground chamber air supply system, also comprises overflow valve 9, pressure meter 10, and it places between compressed air booster 4 and the gas cylinder group 11.
Above-mentioned a kind ofly also comprise choke valve, place gas cylinder group air outlet side based on compressed-air actuated mine refuge underground chamber air supply system.
Above-mentioned is a kind of based on compressed-air actuated mine refuge underground chamber air supply system, and the air pressure in the gas cylinder group 11 is 20～48MPa.
The utility model is following based on the working method of compressed-air actuated mine refuge underground chamber air supply system:
Open low pressure valve 2; (0.6～0.8MPa) through oil water separator 3 entering main air boosters 4 for compressed air in the down-hole air line 1; The supercharging multiplying power is 2 times; (1.2～1.6MPa) through one-level gasholder 5 entering secondary compressed air boosters 6 and secondary gasholder 7, and the supercharging multiplying power is 4 times, and (4.8～5.4MPa) get into tertiary compressed air boosters 8 and gas cylinder groups 11 to the compressed air after the supercharging for compressed air after the supercharging; The supercharging multiplying power is 8 times, and the compressed air pressure after the supercharging is 42MPa.10 on pressure meter shows its rated pressure after compressed air is filled with gas cylinder group 11, does not close then unnecessary gas like valve 2 and discharges from overflow valve 9, and at this moment operating personnel can close low pressure valve 2, and then gas cylinder group 11 is ready.In regular maintenance, if pressure meter 10 shows that pressure descends, then there is gas leakage to take place, then open valve 2 and make gas cylinder group 11 be full of gas once more.During use, open high pressure valve 12, the gases at high pressure that are stored in the gas cylinder group 11 get into reducing valve 13, reduce pressure laggard inbound traffics meter 14 and choke valve 15, and amount is regulated choke valve 15 as required, makes the air capacity that gets in the refuge chamber satisfy the personnel that take refuge and breathes.
