Abstract
The utility model discloses a cooling tower which comprises a tower body, wherein a water distributing pool is arranged at the top of the tower body. The cooling tower is characterized in that a fan and an air heater are arranged on the surrounding of the lower part of the tower body; the fan is connected with the air heater; and a pipeline air cooler is arranged in the tower body. The cooling tower disclosed by the utility model has the advantages as follows: the air heater is additionally arranged to heat wet air in the tower body; meanwhile, the pipeline air cooler is arranged in the tower body to cool partial waste hot inlet water; the temperature of the cooled water is reduced; and through the combination of the air heater and the pipeline air cooler, the water mists in the cooling process are greatly reduced, and the loss of evaporable water is also reduced.
Description
Technical field
The utility model belongs to the cooling device technical field, relates in particular to a kind of cooling tower.
Background technology
Cooling tower refers in tower hot water spray is formed water droplet or moisture film to packing, and from top to down carries out convection heat transfer' heat-transfer by convection with the cold air with heat absorption capacity that flows from bottom to top, and utilizes the leak water cooling device of middle heat of evaporation of water diffusion band.This cooling device is mainly wet cooling tower.Wet cooling tower is again take air-draft-type counter-flow cooling tower pattern as main.
During the design cooling tower, in order to reduce water loss, generally be provided with the water saving fixtures water collection device.It is comprised of row's arc impeller, is arranged on the whole tower section, and effect is to stop hot water and the loose little water droplet that spatters of filler collision formation.Little water droplet is mixed in the damp-heat air of rising, because swerving, is retained down in water collection device.This water saving fixtures are substantially inoperative to the water vapour in the damp-heat air.
The design of cooling tower is carried out according to the evaporation of water principle, is to take heat out of as prerequisite take evaporation and diffusion.Evaporation loss is the water yield that must evaporate for the cooling of finishing water.Therefore, theoretical according to cooling tower, for reaching certain cooling effect, should increase as far as possible evaporation capacity.
Cooling tower is the important heat and mass equipment in the fields such as energy source and power and chemical industry, and its effect is the used heat of discharging the technological process of production, carries out heat and mass transfer process by making recirculated cooling water in cooling tower, with the temperature reduction of recirculated cooling water.To conduct heat and the evaporation dual mode carries out heat exchange with air, the heat transferred air that conducts heat namely directly recirculated water makes its temperature rising to recirculated water in cooling tower; And evaporation is to airborne evaporation air humidity to be increased by recirculated water, is called the latent heat transfer mode.Because the temperature of air in cooling tower raises, and the evaporation saturation pressure increases with its increase in temperature, and the cooling tower outlet is saturated moist air, therefore to account for the share that total amount of heat transmits quite large for latent heat, for large cooling column, winter, latent heat accounted for about 50%, and summer, latent heat then accounted for more than 70%.This heat exchange mode has caused a large amount of evaporated water losses, and evaporation loss is the important component part of cooling tower water loss, also is the water consumption project of enterprise's maximum.The generation of evaporation loss not only causes very large economic loss to enterprise, evaporation loss also forms white water smoke at cat head simultaneously, water smoke flies away with the wind, condense on the process units of cooling tower periphery, alkaline water has serious corrosiveness to process units, to producing, consist of safely great potential safety hazard.
The utility model content
The purpose of this utility model is the problem that exists for prior art, and a kind of cooling tower that water smoke generates that reduces is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cooling tower comprises tower body, and described tower body top is provided with distribution reservoir, and what it is characterized in that described tower body bottom is provided with blower fan and air heater on every side, and described blower fan is connected with air heater, and described tower body inside is provided with the pipeline air cooler.
Described air heater is provided with hot water inlet and cooling water outlet.
The beneficial effects of the utility model: the utility model is simple in structure, can effectively reduce the generation of water smoke, reduces the loss that evaporated water produces.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1, tower body, 2, blower fan, 3, air heater, 4, the pipeline air cooler, 5, distribution reservoir, 6, warm-air pipe, 7, water inlet manifold, 8, hot water inlet, 9, cooling water outlet, the 10, first valve, the 11, second valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Such as Fig. 1.
A kind of cooling tower, comprise tower body 1, described tower body 1 top is provided with distribution reservoir 5, it is characterized in that described tower body 1 bottom around be provided with blower fan 2 and air heater 3, described blower fan 2 is connected connection with air heater, described tower body 1 inside is provided with pipeline air cooler 4.Described air heater 3 is provided with hot water inlet 8 and cooling water outlet 9.
During work, hot water enters from hot water inlet 8, flows out from cooling water outlet 9 through the cold water behind the air heater 3, and pipeline produces hot-air, and blower fan 2 blasts warm-air pipe 6 to hot-air, so tower body inside is covered with hot-air.Hot water enters tower body 1 from water inlet manifold 7, pipeline air cooler 4 coolings of the hot water part of water inlet manifold 7 by being arranged on tower body 1 inside, and another part directly enters distribution reservoir 5.During summer, enter distribution reservoir 5 through pipeline air cooler 4 coolings water section out by opening the first valve 10, another part enters the cooling tower sink by opening the second valve 11, when wintry weather is cold, the first valve 10 is closed, and the second valve 11 is opened, and directly enters the cooling tower sink through pipeline air cooler 4 coolings water out, do not enter distribution reservoir 5, cooling tower does not have water smoke to produce.Tower body 1 interior hot water is through 4 coolings of piping air cooler, and this part water temperature reduces, and passing into air in the pipeline simultaneously is hot-air, and the inner water smoke that produces of cooling tower greatly reduces.
Claims (2)
1. cooling tower, comprise tower body (1), described tower body (1) top is provided with distribution reservoir (5), it is characterized in that described tower body (1) bottom around be provided with blower fan (2) and air heater (3), described blower fan (2) is connected 3 with air heater) connect, described tower body (1) inside is provided with pipeline air cooler (4).
