Description
Technical field
The utility model relates to a kind of film-type evaporation air cooler, has been mainly used in the equipment of process heat medium condenses or cooling.
Background technology
At present, in industries such as oil, chemical industry, electric power, metallurgy, film-type evaporation Air flow obtains applying more and more widely.Known film-type evaporation air cooler is primarily of fan air drum, the tube bank of precooling finned tube, mist eliminator, spray equipment, steam-generating bank, water pump, water tank and shutter composition.When equipment runs, start blower fan air inducing, cold wind is sucked by shutter by air cooler bottom, air duct is discharged after restraining heat exchange with precooling finned tube again after upwards skimming over steam-generating bank, water pump send into cooling water by spray equipment spraying to steam-generating bank, form moisture film on steam-generating bank surface, purged play combination heat transfer effect by water film evaporation and cold wind, shower water falls into water tank collection and stores and recycle.
In actual motion, above-mentioned known film-type evaporation air cooler relies on blower fan air inducing, and its subject matter is: wind turbine layout up, is easily subject to the impact of extraneous strong wind, causes exhaust not smooth, causes cooling heat transferring unstable; Meanwhile, blower fan is in moist air environment for a long time, and the easy accumulation dust of blade surface, causes air draft hydraulic performance decline, also can affect air cooler cooling heat transferring effect.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of film-type evaporation formula air cooler, solve the smooth and easy accumulation dirt problems of fan blade of exhaust that existing film-type evaporation air cooler causes by ectocine, improve air draft performance and air draft stability, thus improve air cooler cooling heat transferring effect and stability.
Film-type evaporation air cooler described in the utility model, comprise air suction device, pre-cooler tube bundle, evaporative air-cooling is restrained, mist eliminator, water injector, water pump, shutter and casing, air suction device comprises the gas skirt being arranged on precooling tube bundle top, gas skirt top arranges aspirating unit, aspirating unit runs through cyclone chamber and arranges, cyclone chamber top arranges exhaust duct, aspirating unit top is positioned at exhaust duct, cyclone chamber arranges blower fan in one end, there is fan air inlet blower fan side, whirlwind road is formed between aspirating unit and exhaust duct, whirlwind road communicates with cyclone chamber, gas skirt, cyclone chamber and exhaust duct all pass through case supports.
When equipment runs, dry air enters blower fan through fan air inlet, blown into whirlwind road, form swirling eddy, rotate along whirlwind road and rise, and form low pressure in aspirating unit upper port, produce suction force, by being gathered in gas skirt after evaporation and heat-exchange, the humid air of aspirating unit lower port is drawn into aspirating unit and enters whirlwind road, and the dry air rotated along with whirlwind road together, enters air through exhaust duct.
Side away from blower fan in described whirlwind road communicates with cyclone chamber.Be convenient to form eddy flow.
Described gas skirt comprises gas collection section and is positioned at the gas collection section at gas collection section top, and gas collection section is set to tubaeform, and its bigger diameter end is below miner diameter end, and miner diameter end is connected with aspirating unit.Be convenient to collect humid air.
The beneficial effects of the utility model are:
Structure is simple, under the prerequisite of main body heat exchange structure keeping known existing film-type evaporation air cooler, adopts suction air assembly, changes the in line air manner of blower fan, make air draft performance better more stable; Humid air after heat exchange enters air through aspirator, solve known existing film-type evaporation fan for air cooler and blade directly contacts humid air, exhaust is large by ectocine, causes the smooth and easy accumulation dirt problems of fan blade of exhaust, improves air cooler heat transfer effect and stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, fan air inlet 2, pre-cooler tube bundle 3, mist eliminator 4, water injector 5, evaporative air-cooling tube bank 6, water pump 7, shutter 8, gas skirt 9, blower fan 10, exhaust duct 11, aspirating unit 12, cyclone chamber 13, whirlwind road 14, casing.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 1, film-type evaporation air cooler described in the utility model, comprise air suction device, pre-cooler tube bundle 2, evaporative air-cooling tube bank 5, mist eliminator 3, water injector 4, water pump 6, shutter 7 and casing 14, air suction device comprises the gas skirt 8 being arranged on pre-cooler tube bundle 2 top, gas skirt 8 top arranges aspirating unit 11, aspirating unit 11 runs through cyclone chamber 12 and arranges, cyclone chamber 12 top arranges exhaust duct 10, aspirating unit 11 top is positioned at exhaust duct 10, cyclone chamber 12 arranges blower fan 9 in one end, there is fan air inlet 1 blower fan 9 side, whirlwind road 13 is formed between aspirating unit 11 and exhaust duct 10, whirlwind road 13 communicates with cyclone chamber 12, gas skirt 8, cyclone chamber 12 and exhaust duct 10 are all supported by casing 14.Communicate with cyclone chamber 12 away from the side of blower fan 9 in whirlwind road 13.Gas skirt 8 comprises gas collection section and is positioned at the gas collection section at gas collection section top, and gas collection section is set to tubaeform, and its bigger diameter end is below miner diameter end, and miner diameter end is connected with aspirating unit 11.
During air suction device work, dry air enters blower fan 9 through fan air inlet 1, dry air is blown into whirlwind road 13 through cyclone chamber 12, form swirling eddy, rotate along whirlwind road 13 and rise, and form low pressure in aspirating unit 11 upper port, produce suction force, by being gathered in gas skirt 8 after evaporation and heat-exchange, the humid air of aspirating unit 11 lower port is drawn into aspirating unit 11 and enters whirlwind road 13, and the dry air rotated along with whirlwind road 13 together, enters air through exhaust duct 10.Heat exchanging process of the present utility model is, the processing medium of cooling is needed first to enter pre-cooler tube bundle 2, with the air-flow heat exchange from evaporative cooling section, carry out precooling, then enter evaporative air-cooling tube bank 5, top water injector 4 sprays downwards, shower water restrains 5 flow downwards at evaporative air-cooling, form moisture film, in the process that outside tube water film flows from top to bottom, the heat of medium in absorption tube, makes water film temperature raise.Meanwhile, the air sucked bottom air cooler skims over moisture film, with moisture film heat convection, because the water capacity in moving air does not reach saturated, therefore the water of water film surface can evaporate and enters air, the humid air after heat exchange rises to the gas skirt 8 of aspirator, enters air through aspirator.
