CN2831014Y - Cooling tower preventing white smoke - Google Patents

Abstract

The utility model discloses a white smoke preventing cooling tower which is mainly composed of a motor, a speed reducer, an air drum, a tower body and radiating fins and is characterized in that radiating fin covers are fixed above the radiating fins at intervals. The utility model has the advantage of simple structure, all circulating water is uniformly showered on the surface of radiating material above which no radiating fin cover is arranged and the circulating water is not showered on the radiating material above which the radiating fin covers are arranged. In this way, the cooling, diffusing and returning process after air exhausted by the cooling tower encounters outside cold air doesn't exceed the saturation curve, so that white smoke can be prevented from being generated and the defect of generating white smoke is overcome.

Description

White-smoke-resisting cooling tower

Technical field:

The utility model relates to a kind of cooling device, relates in particular to a kind of cooling tower of anti-white cigarette.

Background technology:

Among Fig. 2, the x axle represents that dry-bulb temperature, y axle represent that absolute humidity, curve 1 is saturation curve.

When general standard type cooling tower moved under low temperature environment, all recirculated water was evenly dripping in all heat sink material surfaces.By shown in Figure 2, the cooling tower air intake vent enters cool exterior air A, and A contacts with recirculated water, becomes saturation state B through heat absorption, humidification, discharges cooling tower through ventilating fan again.The air B that discharges cooling tower is in saturation state B, meets cool ambient air and cools off, spreads and be returned to state A.This process is condensed and is produced white cigarette in the steam of saturation curve upper lateral part branch.If cooling tower is arranged at by the road, the white cigarette of its generation may influence the driving sight line because of wind direction; The cooling tower of big capacity is arranged at the high building top, and if the white cigarette of its generations is night through the irradiation of ruddiness line, and this moment, white cigarette can become redness, just as roof catches fire, often is mistaken as the building fire and produces in alarm; The white cigarette of cooling tower influences building view or sight line person.

Summary of the invention:

The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, can prevent to produce the white-smoke-resisting cooling tower of white cigarette.

Among Fig. 3, the x axle represents that dry-bulb temperature, y axle represent that absolute humidity, curve 2 is saturation curve.

To achieve these goals, the technical scheme that its technical problem that solves the utility model adopts is, a kind of white-smoke-resisting cooling tower mainly is made up of motor, reductor, wind trunk, tower body and fin, is characterized in: compartment of terrain, fin top is fixed with radiation fin cover.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is simple in structure, is skillfully constructed, whole recirculated waters are the dripping heat sink material surface of not having radiation fin cover in the top evenly, and it is dripping to recirculated water that the top has the heat sink material of radiation fin cover then not have.Thus and thus, by shown in Figure 3, when the cooling tower air intake vent enters cool exterior air A, some carries out heat through having water portion fin to enter to contact with recirculated water, wet exchange, cold air is through heating, humidification and become saturation state B, another part enters through no water section fin, therefore the part air does not contact with recirculated water, become state C so only be heated, the air of state B and state C is discharged cooling tower and is become the air of state D after air compartment and ventilating fan mix, the air of state D is met cool ambient air and is cooled off, diffusion and be returned to state A, this process is because of being no more than saturation curve, just can avoid white cigarette to produce, overcome the defective that produces white cigarette, the tool promotional value.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is cool exterior air of the present utility model and the air themperature of process heat absorption humidification and the curve map of absolute humidity.

Fig. 3 is the curve map of the utility model one embodiment.

The specific embodiment:

Among the figure, a kind of white-smoke-resisting cooling tower, motor 10 is installed on the wind trunk 30 with reductor 20, and reductor 20 and wind trunk 30 all are installed on the tower body 40, and radiation fin cover 50 compartment of terrains are fixed on the fin 60, and fin 60 is installed on tower body 40 inner both sides.Thus and thus, can prevent to produce white cigarette effectively.

Claims (1)

1, a kind of white-smoke-resisting cooling tower mainly is made up of motor, reductor, wind trunk, tower body and fin, it is characterized in that: compartment of terrain, fin top is fixed with radiation fin cover.
