Description
Technical Field

[0002] When a thermal power plant is in operation, a large amount of cooling water is needed to cool the units. The power plant is built near a large water source (reservoir, river, lake and ocean, etc.), and cold water is directly introduced into the power plant through pipes for use.
[0003] Existing thermal power generation equipment requires a large amount of water to cool each unit during operation. The water used for cooling is usually discharged directly into the ditch, which is relatively wasteful. However, when the cooling water is used for heat transfer to cool the unit, the water is heated by high temperature and impurities such as scale will be generated inside it. If this water is not filtered and is discharged into the thermal power generation equipment for use again, it is easy to clog the pipes. In addition, most existing filtering devices filter water from bottom to top, and some sediments will directly settle on the filter below, which is easy to cause clogging of the filter.
