Description

Automatic multi-section cleaning device capable of rotating up and down for diversion channel

Technical Field

However, seawater contains various impurities, shells, fish, shrimp, seaweed and the like, and in order to ensure the normal operation of nuclear power plant equipment, the impurities must be filtered through filtering treatment, and then the nuclear power unit can be cooled.

The final cooling systems of the current commercial nuclear power units are all introduced seawater cooling systems. Foreign matter interception is carried out by fixing a plurality of blocking nets with different mesh sizes on the water taking open channel. After the nuclear power station operates for a period of time, various impurities can be greatly adsorbed on the filter screen, so that the through-flow sectional area of a water taking channel can be reduced, the flow of seawater is reduced, the cooling effect of a unit is influenced, and the hidden danger of safety accidents can be caused to the unit. Therefore, the nuclear power station must clean all impurities on the blocking net in time to ensure the normal flow of seawater. In some extreme cases, such as shrimp tide outbreak and red tide, the large number of organisms may not be cleaned in time, so that the nuclear power unit is forced to reduce power or shut down.
