Cooling tower circulating water automatic filtration and cleaning device

Abstract

The invention discloses an automatic filtering and cleaning device for cooling tower circulating water and relates to the technical field of cooling towers. The automatic filtering and cleaning device for the cooling tower circulating water comprises a collecting tank and a chain type filtering screen, a discharging port is formed in the bottom of the collecting tank, a driving motor is mounted on the collecting tank, a cleaning hairbrush roll and a driving filtering screen roll which is used for winding the chain type filtering screen are mounted in the collecting tank, arranged parallelly and in transmission connection with the driving motor, a driven filtering screen roll is mounted at the bottom of a water return channel below the driving filtering screen roll, and the chain type filtering screen winds on the driving filtering screen roll and the driven filtering screen and can be driven by the driving filtering screen roll to rotate. The automatic filtering and cleaning device for the cooling tower circulating water has the advantages that the filtering screen can be cleaned online continuously, cleaning period of the filtering screen can be prolonged, the amount of overhauling times can be decreased, labor intensity can be reduced, and continuous normal running of the cooling tower can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to an automatic filtering and cleaning device for cooling tower circulating water. Background technique [0002] At present, the natural draft cooling tower is connected to the closed suction well through the backwater ditch, and the circulating water is sprayed down from the cooling tower, enters the water suction well through the backwater ditch, and is sent to the condenser after being pressurized by the circulating pump, so that the cycle reciprocates. [0003] In order to ensure the ventilation volume, the mesh size of the air inlet of the cooling tower should not be too high, and the mesh size is about 5cm×5cm. In this way, some small light solid wastes will be blown into the cooling tower pool with the wind, and the filler debris will also fall into the cooling tower pool with the circulating water. Sundries such as light solid waste and packing debris will flow to th...

AI Technical Summary

Problems solved by technology

In the suction well, because the normal water level cannot be guaranteed, it will cause cavitation of the circulating pump, that is, a vacuum will be formed at the suction port of the circulating pump, and the circulating pump will not be able to pump water normally. Therefore, in order to maintain a normal and reasonable water level in the suction well, the water level of the cooling tower pool will rise. High enough to be higher than the overflow port to cause circulating water to flow out
