Abstract
The invention discloses an environment-friendly water-saving cooling tower, which is a cooler used in cycle water temperature decrease. Wherein, the side wall of tower is symmetry distributed with wind inlet shutters of air cooler; the inner side that near to the shutters is distributed with an air cooler; the water distributing tube at the inner side of air cooler is through to the water inlet tube of cycle water, while the water outlet tube of air cooler is through to the water distributor; the lower water tank of air cooler via the branch tube is through to the reflux tube of recycle water; the air cooler is above the water collector; the water distributor is between two air coolers. The invention uses air cooler to pre-cool the cycle water, to reduce the load of stuff section, the steam amount and the water consumption. And since the air is dry and heat via the air cooler, it can reduce the humidity of hot and humid air that exchanged heat with stuff layer, to reduce the fog at the tower.
Description
Technical field
The present invention relates to a kind of cooling tower that is used for circulating water cooling, it is a plurality of to be widely used in thermal power generation, oil, chemical industry etc.
Technical field.
Background technology
The effect of cooling tower is that the recirculated water that will carry waste heat carries out heat exchange at Ta Nei and air, and the heat of water is transferred to air and spills into atmosphere, and recirculated water is lowered the temperature.Cooling tower is divided into wet cooling tower and two kinds of forms of dry cooling tower by the way of contact of recirculated water and air.
In wet cooling tower, the recirculated water of being sowed at filling surface directly contacts with air, by transmission of heat by contact and evaporative heat loss, the heat of water is transferred to air.The heat exchanger effectiveness height of wet tower, the limiting temperature that water is cooled is the wet-bulb temperature of air.But water causes loss because of evaporation; And evaporation makes the cooling water salinity of circulation increase again, for stabilizing water quality, normal other filter method of dosing and the blowdown method of adopting, wherein blowdown method is because of investment and operating cost is low widely uses, and its processing method higher water of a part of salinity of promptly draining relies on supplementing water to reduce salinity, promptly there is the blowdown loss, must have new water to replenish, in addition, the water that wafts also can cause the loss of water.Simultaneously, damp-heat air can condense into water smoke in the cooling tower exit, causes ambient light contamination and influences the local climate environment.
In dry cooling tower, the heat exchange of recirculated water and air is to conduct heat by the radiator wall, and the heat of managing interior water is transferred to the outer flow air of radiator.Because water does not directly contact with air, so dried tower does not have evaporation of water, so there is not the evaporation of water loss, the cooling tower outlet does not have water smoke yet.But because the cooling limit temperature of dried tower is the dry-bulb temperature of air, and the specific heat of air is little, and the heat-exchange capacity of dried tower is far below wet tower, so dried tower needs a large amount of materials such as metal, so its cost is more than wanting high with capacity wet type tower.
Summary of the invention
The purpose of this invention is to provide a kind of environment-friendly water-saving type cooling tower, it is big and go out Ta Kou water smoke is arranged to be intended to solve the wet cooling tower water loss, and the low problem of dry cooling tower heat exchanger effectiveness, with advantage comprehensive wet, dry cooling tower, make it have environmental protection preferably and water-saving result.
The objective of the invention is to be achieved through the following technical solutions:
A kind of environment-friendly water-saving type cooling tower, contain tower body, be arranged on the water collection device in the tower body, water-locator, packing layer, storage cistern, be arranged on the air intake shutter on the tower body sidewall of packing layer below, circulating water inlet, recirculated water return pipe and corresponding valve, it is characterized in that: symmetric arrangement has aerial cooler air intake shutter on the tower body sidewall of cooling tower, be close to aerial cooler air intake shutter in the tower body inboard and be furnished with aerial cooler, the sparge pipe of described aerial cooler inboard is connected with circulating water inlet, the aerial cooler outlet pipe is connected with water-locator, the lower condensate sump of aerial cooler links to each other with the recirculated water return pipe by bypass pipe, described air cooler is arranged on the top of water-locator, and water collection device is arranged between two aerial coolers.
Technical characterictic of the present invention also is: the top at described tower body is provided with blower fan.
Aerial cooler of the present invention adopts plate wing fin tube type, helical fin tubular type or suit fin tube type structure, and finned tube is pipe, elliptical tube or porous flat pipe, and described fin is straight wing, screw thread wing, ripple wing or venetian blind type wing.Described water-locator adopts goes up spray cloth water-bound.Air and recirculated water are and intersect the reflux type heat exchange in the described aerial cooler.
The present invention compared with prior art, has following beneficial effect by changing the version of cooling tower: 1. owing to be provided with aerial cooler recirculated water is carried out precooling, reduced the cooling load of packing section, reduced evaporated water, can economize on water.2. because air becomes xeothermic through behind the aerial cooler, the hot humid air after the packing layer heat exchange there is the effect that reduces water capacity, can eliminates or reduce the water smoke that tower mouth place produces, help environmental protection.
