Description
Technical field
The present invention relates to one and be applied to the industries such as oil, chemical industry, metallurgy, electric power, complete the equipment of process heat medium condenses or cooling, specifically a kind of precooling humidification evaporation air cooler.
Background technology
At present, due to water conservation, adopt Air flow to obtain applying more and more widely, known air cooler is dry type air cooling pattern mainly, and the main augmentation of heat transfer cooling medium by finned tube, medium, by Air flow, has saved cooling water.But for the situation that outlet temperature requirements is low, dry air cooling is difficult to meet the demands.Since entering last century, a kind of evaporative air-cooling is used widely, it takes away the principle of the evaporation latent heat outside pipe by circulated sprinkling water from top to bottom and air from top to bottom, processing medium can be cooled to close to ambient wet bulb temperature, good cooling results, and floor space is little.What the surface evaporation air cooler evaporative air-cooling of patent 96200559.2 adopted is a kind of light pipe is as heat exchange element, and what upside precooling adopted is the dry and cold device of the horizontal fin tube type of a slice., all there is water spraying time long in other this similar of evaporation air cooler fundamental sum known both at home and abroad, the problem that water saving degree is not high.
Summary of the invention
Technical problem to be solved by this invention is: be to provide a kind of structure more simple, heat transfer efficiency is higher, and unit heat exchange area is large, and in 1 year, water spraying time is short, more evaporating air cooler of economizing on water.
The present invention solves the problems of the technologies described above adopted technical scheme: provide a kind of precooling humidification evaporation air cooler, be made up of pre-cooler tube bundle, evaporative air-cooling tube bank, blower fan, mist eliminator, water injector, water circulating pump, water tank, blower fan is located at above mist eliminator, mist eliminator is in the middle of blower fan and water injector, evaporative air-cooling tube bank is below water injector, evaporative air-cooling tube bank below establish water tank, the invention is characterized in a kind of precooling humidification evaporation air cooler air intake passage on spray equipment is set; Air intake passage comprises evaporative air-cooling tube bank below, air feed shutter is outside window inside side and air feed shutter window, spray equipment can be located at a place or the many places of air intake passage, i.e. evaporative air-cooling tube bank below, the place of air feed shutter outside window inside side and air feed shutter window or many places.Feature of the present invention is also that can arrange pre-cooler tube bundle cools in advance, and the heat exchanger tube of pre-cooler tube bundle can adopt finned tube.
The invention is characterized in that a kind of precooling humidification evaporation air cooler can arrange spray equipment between pre-cooler tube bundle and mist eliminator.Spray equipment can be atomizing spray, is made up of water inlet pipe and spray nozzle, and feature of the present invention is also that spray nozzle has spiral channel.Feature of the present invention is also that the spray equipment on air intake passage and the spray equipment between pre-cooler tube bundle and mist eliminator can be arranged simultaneously, also can arrange respectively.Feature of the present invention is also that the water inlet pipe between steam-generating bank to pre-cooler tube bundle can arrange water treatment facilities.The bobbin carriage of steam-generating bank of the present invention and pre-cooler tube bundle can adopt threaded plug type, and cover-plate type and set tubular type, the heat exchanger tube of steam-generating bank and pre-cooler tube bundle can be U-shaped coil pipe, also can be straight tube.
Operation principle of the present invention is: when summer high temperature, and first processing medium enters pre-cooler tube bundle, under the wind effect of blower fan, carry out precooling, under being cooled to uniform temperature, then enter steam-generating bank, flow in steam-generating bank, open water injector above steam-generating bank, shower water is in the export-oriented current downflow of evaporation tube beam tube, air flows from bottom to top outside pipe simultaneously, and the heat inside pipe, by means of the water outside pipe, pass to air, and be discharged in air.When spring and autumn equitemperature is more gentle, close water injector above steam-generating bank, start the spray equipment of air intake passage, air intake passage spray equipment is made up of water inlet pipe and spray nozzle, current form spiral flow from the spiral channel of spray nozzle, parital vacuum is formed centrally in spiral flow, make current and the violent friction of distinguished and admirable generation, a small amount of water rapid vaporization evaporation, heat around simultaneously stability, the water and air temperature of surrounding is made to reduce temperature rapidly, the reduction of air themperature from bottom to top, the larger temperature difference is formed with steam-generating bank, under low temperature wind action, processing medium in cooling tube, play the effect of atomization humidification cooling, greatly save cooling water, simultaneously owing to only have employed the cooling of atomization humidification, power of fan reduces greatly, save electricity consumption.If outlet temperature requirements is very tight, spray equipment can be set between pre-cooler tube bundle and mist eliminator, in extreme high heat situation, water injector above steam-generating bank can be opened, start steam-generating bank cooling effect, open the spray equipment of air intake passage and pre-spray equipment between cooler tube bundle and mist eliminator simultaneously, air intake passage spray equipment makes the water and air temperature of surrounding reduce temperature rapidly, cooling effect is better, spray equipment between pre-cooler tube bundle and mist eliminator, identical with air intake passage spray equipment principle, reduce the EAT of pre-cooler tube bundle, make pre-cooler tube bundle cooling effect better, make under the condition of extreme high heat, should be able to the cooling of strict guarantee medium.When winter air temperature is lower, stops water spray, adopt dry and cold.Said structure can realize controlling water spray by season, plays the effect of water saving and economize on electricity.
