Description

Technical Field

[0001] The utility model relates to the field of anti-corrosion materials, in particular to an anti-corrosion lining for a water pool of an evaporative cooling tower. Background Art

[0002] Thermal power plants, also known as thermal power plants, are factories that use combustibles as fuel to produce electricity. Thermal power plants are generally built with cooling towers, which are mainly used for circulating water cooling. That is to say, high-temperature pure water can be put back into use after being cooled by the cooling tower. The cooling tower pool refers to the equipment for receiving, concentrating and distributing cooling water. Since cooling water contains certain chemical components and corrosiveness, it will corrode the bottom and walls of the cooling tower pool. At the same time, water vapor penetration, microorganisms and media will also erode the bottom and walls of the cooling tower pool. Therefore, the cooling tower pool is prone to large-scale bulging, cracking and peeling, which makes the cooling tower pool unusable. Utility Model Content
