Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to a kind of cooling tower and pulls out air duct.
Background technology
Current both at home and abroad circulating water tower is to using blower fan to drive air motion as the air power source of cooling tower always, makes outside air and the recirculated cooling water through in tower carry out heat exchange, to reach the object that reduces cooling water.The air duct of tradition mechanical ventilation type cooling tower is circular; under blower fan rotates from extraneous suction air; in inner-tower filling material mobile hot water with from the air of extraneous suction, carry out heat exchange; the defect such as will have like this that actuating unit noise is large, the maintenance cost of actuating unit is high, electric power resource consumption is large and security performance is low, can not meet people to environmental protection, economize on resources, improve the quality of living and the requirement of security.In order to overcome the defect of traditional mechanical ventilation type cooling tower, use without motor cooling tower, can produce new problem without blower fan so again, such as because this kind of calm cylinder of cooling tower tower top, extraneous air inlet is few, causes heat exchange performance low.
Summary of the invention
The technical problems to be solved in the utility model is, the above-mentioned defects such as maintenance cost large for the actuating unit noise of circulating water cooling tower in prior art, actuating unit is high, electric power resource consumption is large, security performance is low and heat exchange performance is low, provide a kind of simple in structure, noise is little, maintenance cost is low, pull out wind the efficiency high and energy-conservation cooling tower of heat exchange performance, security performance high, that can improve cooling tower pulls out air duct.
The utility model solves the technical scheme that its technical problem adopts: a kind of cooling tower pulls out air duct, comprise a plurality ofly pulling out air duct stage casing and a plurality ofly pulling out air duct angle, and pull out between air duct stage casing by pull out air duct angle connect and form there is hollow cavity pull out air duct body; Pulling out air duct body top is air outlet, and its bottom is air-vent, and the internal diameter of hollow cavity that pulls out air duct body first diminishes gradually from top to bottom, then becomes gradually large; Pull out air duct stage casing and pull out the top at air duct angle and bottom between be respectively equipped with Yu Tong Jiao Bafeng district, Ba Feng district, ，Qie stage casing, He Tong Jiao Bafeng district, Ba Feng district, stage casing and be communicated with.
In technical scheme described in the utility model, described cooling tower pull out air duct comprise by a plurality of pull out air duct stage casing and a plurality of pull out that air duct angle is spliced to form pull out air duct body, this pulls out air duct body and has hollow cavity, and the internal diameter of this hollow cavity first diminishes gradually from top to bottom, become gradually larger, in addition, the middle part of pulling out air duct body is also provided with by He Tong Jiao Bafeng district, Ba Feng district, stage casing and forms Ba Feng district, therefore it is not only simple in structure that described cooling tower pulls out air duct, and such design has improved the heat exchange performance of cooling tower greatly, increased the ability that guarantees cooling tower safe operation, improved security performance, in addition, can also reduce water pump water supply consumption, saved the energy.
In technical scheme described in the utility model, the internal diameter that pulls out the hollow cavity of air duct body first diminishes gradually from top to bottom, become gradually larger, the top of pulling out air duct body is diffusion type curve shape, its bottom is tapering type curve-like, the air outlet of diffusion type curve shape has not only reduced the kinetic energy rejection of air outlet, and can also prevent that the damp-heat air of discharging from cooling tower from flowing back in cooling tower, tapering type curvilinear air-vent can reduce the resistance of air-vent, makes air-vent more smooth and easy without hindrance; In addition, by the connection of He Tong Jiao Bafeng district, Ba Feng district, stage casing, form Ba Feng district and also increased the ability that sucks extraneous air-flow, also increased the intensity that described cooling tower pulls out air duct, what these had all improved that described cooling tower pulls out air duct greatly pulls out wind efficiency, has also reduced noise when cooling tower pulls out air duct work simultaneously.
In technical scheme described in the utility model, the described air duct that pulls out is arranged on cooling tower tower top, without the rotation by blower fan from extraneous air amount, and the cooling tower that pulls out air duct with nothing is compared, cooling tower described in the utility model relies on the air duct that pulls out of its tower top to increase by 30% from the throughput of external world's suction, so not only avoid producing noise, but also greatly reduce the maintenance cost of cooling tower.
As a kind of improvement to technical scheme described in the utility model, pull out and on air duct stage casing, be provided with vertical strengthening ribs and cross reinforcing.The vertical strengthening ribs and the cross reinforcing that pull out on air duct stage casing contribute to reinforcement to pull out the intensity in air duct stage casing.
As a kind of improvement to technical scheme described in the utility model, pull out and on air duct angle, be provided with vertical strengthening ribs and cross reinforcing.Pull out the vertical strengthening ribs and the cross reinforcing that on air duct angle, arrange and improved the intensity of pulling out air duct angle.
As a kind of improvement to technical scheme described in the utility model, pulling out air duct angle is arc corner.
As a kind of improvement to technical scheme described in the utility model, pull out air duct stage casing and adopt fiberglass or polyvinyl chloride to make.
As a kind of improvement to technical scheme described in the utility model, pull out air duct angle and adopt fiberglass or polyvinyl chloride to make.
In addition, in the technical scheme described in the utility model, all being not specifically noted, all can be by adopting the routine techniques in this area realize the technical program.
Therefore, the beneficial effects of the utility model have been to provide a kind of cooling tower and have pulled out air duct, and it is simple that this cooling tower pulls out Wind cylinder structure, and noise is little, and maintenance cost is low, pull out wind efficiency high, can also improve the heat exchange performance of cooling tower, and security performance is high, and good energy-conserving effect.
