In figure: 1 is compressed air feedway, 2 is air curtain spray system, and 3 is ice-storage air-conditioning system, 4 is the first pipeline, and 5 is second pipe, and 6 is bus dump, 7 is shunt conduit, and 8 is compressed air bottle, and 9 is the first one-level decompressor, 10 is the second one-level decompressor, 11 is second depressurized device, and 12 is control valve, and 13 is Pressure gauge, 14 is air curtain device, and 15 is spray equipment 15.
Detailed description of the invention
In the present embodiment, compressed-air supply system can be applicable in the refuge chamber under mine, as shown in Figure 1, compressed-air supply system, including: compressed air feedway 1, air curtain spray system 2 and ice-storage air-conditioning system 3, wherein, air curtain spray system 2 includes air curtain device 14 and spray equipment 15, compressed air feedway 1 supplies to ice-storage air-conditioning system 3 by the first pipeline 4, and compressed air feedway 1 supplies to air curtain spray system 2 by second pipe 5;Described compressed air feedway 1 includes: bus dump 6 and at least one shunt conduit 7, the gas outlet of each shunt conduit 7 is all connected with bus dump 6, in the present embodiment, having at least one air inlet on described bus dump 6, each air inlet is connected with shunt conduit 7 gas outlet the most correspondingly;The air inlet of each shunt conduit 7 is respectively connected with a compressed air bottle 8, it is equipped with control valve 12 in each shunt conduit 7, when there being compressed air bottle 8 that leakage occurs, the control valve 12 corresponding with this compressed air bottle 8 is closed, the use of remaining compressed air bottle 8 is unaffected, specifically, described control valve 12 can be angle pedestal valve.
The two ends of described bus dump 6 are connected with the first pipeline 4 and second pipe 5 respectively, and the quantity of described shunt conduit 7 and compressed air bottle 8 depends primarily on the comprehensive air consumption of air curtain spray system 2 and ice-storage air-conditioning system 3;In the present embodiment, described bus dump the 6, first pipeline 4 and second pipe 5 can be seamless steel pipe, bus dump 6 dispatch from the factory before after 22.5MPa pressure, 30min pressure test No leakage, fully meet the use demand that air high pressure confluxes;In the present embodiment, can be managed by G5/8 between bus dump 6, each compressed air bottle 8 with each shunt conduit 7 and threaded, and each shunt conduit 7 can be all rustless steel high-pressure hose, the end of flexible pipe uses 60 ° of conical surface seal technology, the high pressure of 22.5MPa can be born, meet the pressure requirements of system.
Described first pipeline 4 is provided with the first one-level decompressor 9, described second pipe 5 is provided with the second one-level decompressor 10, in the present embodiment, first one-level decompressor 9 is " right side is entered a left side and gone out " type, second one-level decompressor 10 is " left side is entered the right side and gone out " type, the compressed air being collected in bus dump 6 is transported to ice-storage air-conditioning system 3 and air curtain spray system 2 after the first one-level decompressor 9 and the second one-level decompressor 10 reduce pressure respectively, owing to the operating pressure of air curtain spray system 2 is about 0.4MPa, therefore a second depressurized device 11 can be set up on second pipe 5, specifically, described second depressurized device 11 is arranged on the second pipe 5 between the second one-level decompressor 10 and air curtain spray system 2, and ice-storage air-conditioning system 3 can be used directly the gas of bus dump 6 output as power source;Additionally, Pressure gauge 13 can be arranged on described bus dump 6, the gas pressure in bus dump 6 can be observed intuitively from Pressure gauge 13, to make suitable adjustment, it is ensured that whole feed system properly functioning.
Present configuration is simple, easy to operate, use the compressed air high pressure mode of confluxing to substitute existing low pressure to conflux mode, greatly reduce manufacturing cost, all of compressed air bottle 8 is carried out centralized arrangement, improves the utilization rate in refuge chamber space, use seamless steel pipe to instead of stainless steel tube as supply air line, increase pipeline latus rectum, reduce pressure loss;Above in conjunction with accompanying drawing, embodiments of the invention are explained in detail, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to various changes can be made on the premise of without departing from present inventive concept.
