Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a double-side air-inlet type composite flow closed cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from the system and discharging it into the atmosphere to reduce the water temperature.

[0003] The cooling tower consists of a tower body, a water distribution system, a water sprinkling device, a ventilation system and a water collection tank. The tower body is often built in a circular, rectangular or polygonal shape. There are two types of cooling towers: wet and dry. According to the direction of air and water flow, cooling towers can be divided into countercurrent and crossflow types; according to the ventilation method, they can be divided into natural ventilation cooling towers and mechanical ventilation cooling towers. The function is to transfer the heat in the water to the air and diffuse it into the atmosphere, thereby achieving the effect of reducing the heat in the water. It is mainly used for air room temperature regulation, manufacturing and processing.

[0004] The working principle of the cooling tower is to use water and air to flow in contact, generate steam during the flow contact process, and use the steam to evaporate and take away heat, thereby achieving the effect of cooling and heat dissipation. Therefore, some cooling towers use two or more groups of cooling at the same time to improve the cooling efficiency, thereby improving the cooling effect. This scheme proposes to increase the heat exchange area of ​​the tube bundle, increase the flow contact area of ​​water and air in the cooling tower through the form of double-port air inlet, and then increase the heat exchange rate of steam through the air flow device, thereby achieving the effect of improving the cooling efficiency. For this reason, this scheme proposes a double-sided air inlet composite flow closed cooling tower. Utility Model Content

[0005] The purpose of the utility model is that the heat exchange efficiency of the existing cooling tower cannot keep up with the requirements of some settings. In order to improve the heat exchange efficiency of the cooling tower, this scheme proposes a double-sided air inlet composite flow closed cooling tower.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A double-sided air inlet type composite flow closed cooling tower comprises a cooling tower body, a group of circular holes are opened on the cooling tower body, a rectangular hole is opened on the cooling tower body, a dust screen is matched in the hole, and an air intake assembly is also included, the air intake assembly comprises an air intake pipe, the air intake pipe is installed in the circular hole on the cooling tower body, a support plate is installed on the air intake pipe, a motor is arranged on the support plate, a fan is arranged at the output end of the motor, a collar is matched on the air intake pipe, a rectangular hole is opened on the collar, a limit plate is matched on the hole, a filter screen is arranged at the bottom of the limit plate, a cover plate is matched on the limit plate, and a group of air intake holes are opened on the cover plate.

[0011] Preferably, a group of rectangular holes are opened on the cooling tower body, and spray heads are arranged in the holes.

[0012] The utility model has the following beneficial effects:

[0013] The fan is driven by the motor to rotate, thereby accelerating the circulation speed of the air in the intake pipe, and then a filter device is installed in the cavity composed of the limit plate and the filter screen to filter out the dust in the air. At the same time, some other substances can be intercepted on the top to avoid clogging of the filter screen. Under the action of the sprinkler head, the first tube bundle and the second tube bundle attach some water mist to the surface. At this time, the wind output by the air pipe passes through the first tube bundle and the second tube bundle, so that the heat transferred to the first tube bundle and the second tube bundle by the heat exchange tube is discharged from the rectangular holes on both sides through the airflow, thereby achieving the effect of improving efficiency.
