Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cleaning device for a spray water tank of a closed cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the flow of water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. This is an evaporative heat dissipation device to ensure the normal operation of the system. After long-term use, there will be certain impurities and scale in the spray water tank of the cooling tower. If it is not cleaned in time, it will affect the cooling efficiency of the device.

[0003] After searching, in the prior art, the utility model with publication number CN220311226U discloses a closed cooling tower water tank cleaning mechanism, which is arranged on the tank body, including a sweeping brush plate, a steel brush, a spray pipe and a nozzle, the bottom of the tank body is arranged in an inclined shape, a drain pipe and a cleaning pipe are arranged on the tank body, the height of the drain pipe is lower than the height of the cleaning pipe, the sweeping brush plate is slidably arranged in the tank body, the sweeping brush plate is arranged along the width direction of the tank body, the steel brush is connected to the sweeping brush plate, the steel brush can slide against the bottom of the tank body, the tank body is provided with a driving assembly for driving the sweeping brush plate to move along the length direction of the bottom of the tank body, the spray pipe is connected to the end of the cleaning pipe penetrating into the tank body, the spray pipe is arranged along the width direction of the tank body, the nozzle is connected to the spray pipe, the nozzle is arranged along the length direction of the spray pipe, and the spray pipe can be connected to an external device to pass a medicament to decompose scale or rinse with clean water. The application has the effect of improving the problem of manual entry into the tower for manual cleaning of the water tank and reducing the consumption of manpower and material resources. When the above method is used, the sweeping brush plate needs to move back and forth to clean the trough body. However, during the reciprocating movement of the sweeping brush plate, some impurities remaining in the trough body will be pushed back into the trough body by the sweeping brush plate. After a long time, it is easy to cause impurities to accumulate in the corners of the trough body, affecting the overall practicality. Utility Model Content
