The mine of the utility model adopts three grades of air handling processes with aeration-cooling device.
7 formation first order air handling processes are managed in header tank a4, water filter 5, circulating water pump a6, a pouring pipe 7, return air inlet 18, air outlet 20 and a pouring.The tubular indirect evaporative cooling section is provided with two standpipes and evenly keeps supplying portion and middle part and drip dripping of pouring downwards and drench 7 pairs of tube walls of pipe and drip pourings, drips and drenches pipe 7 layered arrangement, makes water distribution even, drips a pouring and manages 7 and open in summer, as pre-cooler; Close winter, as the outer new wind of gas-to-gas heat exchanger preheating chamber.Water is extracted out from header tank a4 from dripping 7 of pouring pipes through circulating water pump a6 and is drenched; Make water evenly to drip pouring on tube wall; And fully contact with auxiliary air, the temperature that reduces auxiliary air is also taken away the heat of primary air in the pipe, makes primary air promptly be processed air by precooling.
The high-pressure jet section that compressed air piping 8, high-pressure jet standpipe 9 and high pressure solar term nozzle 10 constitute is a second level air handling process.The high-pressure jet section adopts the universal compressed air in the mine, delivers to high pressure solar term nozzle 10 through universal compressed air duct 8 with high-pressure jet standpipe 9, and is carried out adverse current by the air after tube type indirect evaporative cooler 3 precoolings and mixes, to its moisture absorption of lowering the temperature.
The direct evaporative cooling section of spray chamber that header tank b11, circulating water pump b12, water supply standpipe 13 and hydrokinetic type target formula impinging stream nozzle 14 constitute is a third level air handling process.Adopt three row's water supply standpipes 13; Every row has three water supply standpipes; Utilizing circulating water pump b12 to deliver to 14 pairs of air of hydrokinetic type target formula impinging stream nozzle to the water in the header tank b11 through standpipe 13 sprays; Water absorbs heat vaporization time air by the humidification of lowering the temperature from air, this is that a kind of air and water of adopting directly contacts the lower the temperature method of humidification of air.
Roughing efficiency air filter 2 can purify outdoor air, and tube type indirect evaporative cooler 3 is played the proofing dust and protecting effect, improves the caloic exchange efficiency of moisture film and air.
Water among the header tank a4 will pass through water filter 5 and handle, to prevent circulating water pump a6 and to drip the delivery port blockage phenomenon of drenching pipe 7.
The watertight shutter 15 that is provided with after the direct evaporative cooling section of spray chamber adopts ripple watertight shutter 15, and the airborne separated form water that will pass through spray chamber goes out, and is processed the water yield of taking away in the air with minimizing.
Ventilator 16 is the air that is processed to be sent into conditioned area through air outlet 17 wherein air is carried out cool-down dehumidification handle.
The course of work of the utility model device:
Summer; After outdoor new wind filtered dust through roughing efficiency air filter 2 through fresh wind port 1 entering, through tube type indirect evaporative cooler 3, water pressurizeed the water that purified in the header tank a4 through circulating water pump a6 simultaneously; Drench the pipe outer wall through dripping 7 of pouring pipes again; Water leans on action of gravity to dirty wet tube outer wall and form moisture film, adopts return air in the mine to carry out with moisture film as the secondary wind of tube type indirect evaporative cooler 3 that heat is wet to be exchanged, thereby to managing wet coolings such as interior primary air carries out.The air of the preliminary cooling of quilt gets into the high-pressure jet section, mixes with the high-pressure jet of the dry low temperature that sprays through compressed air piping 8, high-pressure jet standpipe 9 and high pressure solar term nozzle 10, and its moisture absorption of lowering the temperature is handled, and improves the wet-bulb depression that is processed air.At the direct evaporative cooling section-spray chamber of the third level, water,, and is processed air and carries out the wet exchange of heat again through standpipe 13 and nozzle 14 ejections the water in header tank b11 pressurization through circulating water pump b12, and air is carried out the constant enthalpy humidification of lowering the temperature.Be processed air then and pass through ripple watertight shutter 15 again, go out airborne separated form water, reduce the water yield of carrying secretly in the air, through air outlet 17 air that is processed is sent into conditioned area by ventilator 16 at last.
In winter, tube type indirect evaporative cooler 3 uses as preheating device.After the outdoor new wind that is processed filters dust through roughing efficiency air filter 2 through fresh wind port 1 entering; Get into again in the pipe of tube type indirect evaporative cooler 3; Close circulating water pump a6; Utilize the high temperature return air of mine to carry out indirect heat exchange, to outdoor new wind preheating, again it is carried out heat treated as gas-to-gas heat exchanger as secondary wind and primary air.
