Description
Technical field
The present invention relates to a kind of cooling tower of refrigeration technology field, particularly be a kind of adverse current type hermetic cooling water tower.
Background technology
Compare with the open type cooling water tower, the cooling water of closed cooling water tower does not contact with air, and airborne dust can't enter the cooling water loop of system, so cooling water non flouling behaviour in cleaning and the heat exchanger tube relatively.For the wet type closed cooling water tower, arrange in tower that usually filler realizes spraying the water and air heat and mass, also have by arranging that in tower metal tube also had been a heat and mass pipe between shower water and the air as the heat exchanger tube of be cooled fluid and shower water both.For the wet type cooling tower of arranging filler, shower water directly contacts with air in the long-time running process, and therefore the water quality deterioration of shower water causes filler to stop up easily and make the cooling tower performance descend.For the cooling tower of heat and mass pipe of metal tube (normally copper pipe) as the spray water and air, because the required heat exchange area of spray water and air heat and mass transfer process is usually greater than the heat exchange area of shower water with the fluid that is cooled, therefore cause the quantity of metal tube in the cooling tower to increase, the manufacturing cost of system increases.In addition, the heat exchange between the fluid that is cooled of common wet type closed cooling water tower, the spray water and air generally all is a following current heat exchange form, and the radiating efficiency of system is poor.
Through the literature search of prior art is found, Chinese patent application number is: 200510120436.5, and name is called: evaporation type sealed cooling cistern.This technology discloses a kind of by the closed cooling water tower of coating porous hygroscopic material on outside the metal tube of radiator coil tube as air and shower water heat and mass media.In metal tube shower water process, water is adsorbed on the porous material at sprinkling equipment; And at air-supply arrangement during with the blows air over metal tube, the shower water constant-temperature evaporation that adsorbs on the porous material, the heat energy that has absorbed the fluid that is cooled in the metal catheter reaches the effect of heat radiation.But because the porous hygroscopic material has covered part metals pipe area, make that the heat exchange area between metal tube and the shower water reduces, so the increase of the quantity of the metal tube of arranging in the cooling tower, manufacturing cost also rises.In addition, adsorbed water in the porous material hole generally is the evaporation earlier of the outermost adsorbed water of hole, and in evaporation process, still have part water to be adsorbed in the hole, therefore in the process of fluid outermost layer water transmission heat in hole that is cooled, be equivalent to increase a thermal conduction resistance that constitutes by the adsorbed water in the hole, be unfavorable for the cooling tower heat transfer process.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, proposed a kind of adverse current type hermetic cooling water tower, make it higher with respect to traditional closed cooling water tower radiating efficiency; Utilize plastic tube or other cheap tubing to replace metal tube or filler, so the cost of system is lower, performance is more reliable and more stable.
The present invention is achieved by the following technical solutions, the present invention includes to flow to end shunting house steward, heat and mass unit, heat transfer unit, spray pond, blowoff valve, air-supply arrangement, housing, watering device, shower water discharge connection, outflow end conflux house steward, shower water inlet connection, spray pump.
