Abstract
The invention relates to a closed cooling tower which comprises a housing, a fan, a coil pipe and a sprayer. The closed cooling tower is characterized in that an air inlet is formed in one side of the housing; the fan is mounted at the air inlet; an air exhaust window is formed in the top of the housing; the coil pipe is arranged in the housing; a hot fluid inlet of the coil pipe is formed in the upper part of the coil pipe; a cold fluid outlet of the coil pipe is formed in the lower part of the coil pipe; the sprayer is arranged right above the coil pipe; a water receiving groove is formed in the bottom of the housing right below the coil pipe; and a drainage port is formed in one side of the lower part of the water receiving groove, and is connected with a water inlet of the sprayer by a spraying pump and a circulating pipeline. The closed cooling tower is simple in structure and reasonable in design; the housing is filled with fillers, so that the residence time of cooling water is prolonged; a heat exchange area is increased; the heat exchange amount is increased; and a cooling effect is improved.
Description
Technical field
The present invention relates to a kind of cooling device, specifically relate to a kind of closed cooling tower, belong to the cooling device technical field.
Background technology
Closed cooling tower (also being evaporating air cooler or closed cooling tower) is cooling device commonly used in producing, and it generally is that pipe heat exchanger is placed in the tower, the heat exchange assurance cooling-down effect of air, shower water and recirculated water by circulation.Owing to be closed cycle, it can guarantee that water quality is not contaminated, has well protected the efficient operation of main equipment, has improved service life.When outside air temperature is low, can cut off water-spray system, play water-saving result.Along with the enforcement of national energy-saving and emission-reduction policy and the scarcity day by day of water resource, closed cooling tower had obtained using widely in industries such as Ferrous Metallurgy, power electronics, machining, air-conditioning systems in recent years.But require than higher occasion in some cooling, existing closed cooling tower can't meet the demands, and strengthen cooling capacity if desired and will increase the cooling tower volume, and this can greatly be subjected to the restriction of installing space.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of closed cooling tower is provided, it is simple in structure, and is reasonable in design, good cooling results.
According to technical scheme provided by the invention: closed cooling tower, comprise housing, blower fan, coil pipe and spray thrower, it is characterized in that: described housing one side is provided with air inlet, and described blower fan is installed in the air inlet place, and described case top is provided with ventilation window; Described coil pipe is arranged in the housing, and the hot fluid import of coil pipe is last, and the cold fluid outlet is following; Be provided with spray thrower directly over coil pipe, the housing bottom under coil pipe is provided with water receiving tank, and described water receiving tank bottom one side is provided with discharge outlet, and discharge outlet is connected with the water inlet of spray thrower with circulation line by spray pump.
As a further improvement on the present invention, under the described coil pipe, be provided with filler in the space directly over the water receiving tank.
As a further improvement on the present invention, the version of described filler is honeycomb fashion.
As a further improvement on the present invention, the ventilation window of described case top is provided with dehydrator.
As a further improvement on the present invention, described water receiving tank is provided with water supplement port, overfall and sewage draining exit.
The present invention compared with prior art, advantage is:The present invention is simple in structure, and is reasonable in design, by increased filler in housing, prolonged the cooling water time of staying, increases heat exchange area, increases the heat exchange amount, improved cooling effect.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the closed cooling tower among the embodiment mainly is made up of parts such as housing 1, blower fan 2, water receiving tank 3, spray pump 4, circulation line 5, filler 6, coil pipe 7, spray thrower 8 and dehydrators 9.
As shown in Figure 1, described housing 1 one sides are provided with air inlet, and described blower fan 2 is installed in the air inlet place, and described housing 1 top is provided with ventilation window; Described coil pipe 7 is arranged in the housing 1, and the hot fluid import 7a of coil pipe 7 is last, and cold fluid outlet 7b is following; Be provided with spray thrower 8 directly over coil pipe 7, housing 1 bottom under coil pipe 7 is provided with water receiving tank 3, and described water receiving tank 3 bottoms one side is provided with discharge outlet, and discharge outlet is connected with the water inlet of circulation line 5 with spray thrower 8 by spray pump 4; Described filler 6 is arranged under the coil pipe 7, in the space directly over the water receiving tank 3, filler 6 can prolong the cooling water time of staying, increases heat exchange area, increases the heat exchange amount.In the embodiment of the invention, the version of described filler 6 is honeycomb fashion.
As shown in Figure 1, in order to reduce the steam vapour amount of taking out of when air is discharged, prolong the moisturizing time, the ventilation window at described housing 1 top is provided with dehydrator 9.In addition; described water receiving tank 3 is provided with water supplement port, overfall and sewage draining exit, and water supplement port is used for replenishing the lack of moisture that causes because of cooling water evaporation, and overfall is used for preventing hypervolia in the water receiving tank 3; the protection cooling tower, sewage draining exit is used for clearing up the foreign-matter contamination in the water receiving tank 3.
During concrete the application, hot fluid enters coil pipe 7 from hot fluid import 7a, flows out from cold fluid outlet 7b after the fluid interchange in coil pipe 7; Blower fan 2 starts, the suction cold dry air also blows in the housing 1, cold dry air is bottom-up circulation in housing 1, cold dry air when the filler 6 with exchange heat of cooling water realization, by coil pipe 7 time, carry out secondary exchange heat again, can improve heat exchange efficiency greatly like this, strengthen cooling effect.
Need to prove that above-mentioned description is only used for description and interpretation the present invention, is not the restriction to protection domain of the present invention.For the person of ordinary skill of the art, the simple modification that the technical scheme of putting down in writing with reference to the present invention is carried out or simple the replacement are all within protection scope of the present invention.
