Description

Technical Field

[0001] The utility model relates to the technical field of packed cooling towers, and particularly relates to a filtering device for a cold water tank in a packed cooling tower. Background Art

[0002] A packed cooling tower is a new type of cooling device that uses packing as the gas-liquid contact surface of the tower; during the operation of the packed cooling tower, hot water enters the top of the cooling tower through a pipeline and is evenly sprayed on the packing inside the tower through a nozzle. At the same time, an air inlet is provided at the bottom of the cooling tower, and air enters the tower through the air inlet. The air contacts the packing, absorbs the heat on the surface of the packing, and realizes the cooling of the hot water. The cooling water flows out from the cold water tank at the bottom of the cooling tower and returns to the industrial equipment, constantly circulating until the hot water is cooled to the required temperature.

[0003] As an important part of the packed cooling tower, the packing is prone to the phenomenon of packing fragments falling off after long-term use. The fallen packing fragments flow with the water flow in the cold water tank and are eventually likely to block the water outlet of the cold water tank; in addition, when the cooling tower operates in winter with relatively low temperatures, ice is likely to form at multiple positions inside the tower. Under the action of the internal air flow and water flow in the cooling tower, the ice cubes are likely to break away from their original positions and fall into the cold water tank, forming floating ice. The floating ice flows with the water flow in the cold water tank and is eventually likely to block the water outlet of the cold water tank.

[0004] There is a certain research on the treatment of ice cubes in the cooling tower in the prior art. Refer to the patent document with the application number 202320529321.5, which discloses a cooling tower deicing device, including: an external network steam pipeline and a cooling tower. A group of steam main control valves are arranged at the end of the external network steam pipeline. A steam branch pipe for steam shunting is connected to the port of the steam main control valve. Each opening of the steam branch pipe is connected with a steam sub-control valve, and several groups of steam branch pipes are arranged on the steam sub-control valve; by using the steam main control valve, the steam branch pipe, the steam sub-control valve and the steam branch pipes in cooperation, jet air at the ice cubes, and the ice cubes are heated and melted to achieve the removal of the ice cubes.

[0005] It can be seen from this that in the prior art, only the ice cubes in the packed cooling tower can be removed by the method of jetting air, and the fallen packing fragments cannot be removed. The fallen packing fragments gather in the cold water tank, affecting the flow of the water flow in the cold water tank. Summary of the Utility Model

[0006] In order to solve the technical problems in the background art that the fallen packing fragments and floating ice cannot be removed simultaneously, and the fallen packing fragments gather in the cold water tank, affecting the flow of the water flow in the cold water tank, the utility model provides a filtering device for a cold water tank in a packed cooling tower.

Operators collect the packing fragments and floating ice located in the collecting part, so that the packing fragments and floating ice in the cold water pool can be removed simultaneously, ensuring the smooth flow of water in the cold water pool.
