Water is scattered above the air filter through the second water distributor and then flows down along the air filter to take away dust filtered on the air filter, so that the air filter is kept clean. And water flowing down from the air filter enters the water collecting tank and then is fed into the second water distributor by the water pump. And the circulation is repeated to realize automatic cleaning of the air filter. According to the utility model, the pollution of dust in the air to water in the cooling tower can be reduced, and the maintenance workload is very small.

Description

Technical Field

[0001] The utility model relates to the technical fields of building cooling and industrial cooling, in particular to a novel cooling tower. Background Art

[0002] Cooling towers are widely used in building cooling and industrial cooling occasions. In the prior art, the working principle of a cooling tower is as Figure 1 shown. After the water to be cooled enters the cooling tower, it is evenly distributed above the packing through a water distributor, and then flows down along the packing and falls into the water collecting tray. Driven by a fan, air passes through the packing. Heat and mass transfer occur between the air and the water in the packing, and the water is cooled.

[0003] There are two situations in the prior art. The first is to let air directly enter the cooling tower. Since there is a lot of dust in the air, when the air cools the water, the dust is also carried into the water, resulting in the water being easily contaminated, which will pollute the subsequent process equipment and reduce its performance. The second is to set an air filter at the air inlet of the cooling tower. Due to the very large ventilation volume of the cooling tower, the set air filter is very easy to get dirty, and the workload of maintaining the air filter is very large. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In order to solve the problems existing in the above background art, the utility model provides a novel cooling tower. Compared with the prior art, the utility model can reduce the pollution of the water in the cooling tower by dust in the air, and at the same time, the workload of maintaining the air filter is very small.

[0006] (2) Technical Solutions

[0007] The utility model provides a novel cooling tower, including:

[0008] A housing, which is in a cylindrical structure and is placed vertically, and has an opening on its side wall;

[0009] A fan, which is connected to the upper opening of the housing, and the fan drives air to enter the interior of the housing from the side wall opening of the housing and discharge from the upper opening of the housing;

[0010] A packing, which is in a honeycomb structure and is located inside the housing. When the fan drives air to flow inside the housing, all the air passes through the packing, and the water falling on the packing can flow along the surface of the packing and finally flow out of the packing downward;

[0011] A first water distributor, which is located inside the housing and above the packing, and water can be evenly distributed above the packing through the first water distributor;

[0012] The water collecting tray is in a disc shape and is located below the packing. It is connected to the lower end opening of the housing, and there is a water outlet on the water collecting tray.

[0013] The air filter is located outside the housing, at the side wall opening of the housing, and completely covers the side wall opening of the housing. When the fan drives air to enter the interior of the housing through the side wall opening of the housing, all of this air passes through the air filter.

[0014] The second water distributor is located above the air filter, and water can be evenly sprinkled above the air filter through the second water distributor.

[0015] The water collecting tank is in a trough shape and is located below the air filter. Water falling from the air filter can completely fall into the water collecting tank.

[0016] The water pump has its inlet end connected to the water collecting tank and its outlet end connected to the second water distributor. The water pump sends the water in the water collecting tank into the second water distributor.

[0017] The water level switch of the water collecting tank is an electric circuit switch, which is installed on the water collecting tank, and its switch state indicates whether the water level in the water collecting tank reaches a specified height.

[0018] The automatic water replenishing valve of the water collecting tank is an electric water valve, which is opened when powered on and closed when powered off, and is connected to the side wall of the water collecting tank through a water pipe.

[0019] The automatic water draining valve of the water collecting tank is an electric water valve, which is opened when powered on and closed when powered off, and is connected to the bottom surface of the water collecting tank through a water pipe.

[0020] Further, the water level switch of the water collecting tank is a float switch or a duckbill switch, and its material is plastic or stainless steel.

[0021] The operation mode of the present utility model is as follows:

[0022] When the fan operates, it drives air to enter the interior of the housing through the air filter. The air undergoes heat and moisture exchange with water on the surface of the packing to cool the water.

[0023] When the air filter needs to be cleaned, close the automatic drain valve of the water collection tank. Judge the water level of the water collection tank according to the status of the water level switch of the water collection tank. If the water level of the water collection tank is lower than the specified height, turn off the water pump and open the automatic water replenishing valve of the water collection tank to replenish water into the water collection tank. If the water level of the water collection tank is equal to or higher than the specified height, close the automatic water replenishing valve of the water collection tank and start the water pump. After the water pump is started, the water in the water collection tank is sent to the second water distributor. The water is sprinkled above the air filter through the second water distributor and then flows down along the air filter, taking away the dust on the air filter. The water flowing down from the air filter enters the water collection tank and is then sent to the second water distributor by the water pump. This process repeats to clean the air filter.

[0024] After the air filter is cleaned, stop the water pump and close the automatic water replenishing valve of the water collection tank. Open the automatic drain valve of the water collection tank to drain the sewage in the water collection tank.

[0025] (III) Beneficial effects

[0026] Compared with the prior art, the utility model is provided with an air filter at the air inlet of the cooling tower and realizes the automatic cleaning of the air filter. Therefore, the utility model can reduce the pollution of the water in the cooling tower by dust in the air, and at the same time, the workload of maintaining the air filter is very small.

[0027] Furthermore, in the utility model, the water level switch of the water collection tank is a float switch or a duckbill switch, and its material is plastic or stainless steel, which can accurately indicate the water level in the water collection tank and has good anti-corrosion performance.
