Application of rotary trash cleaner at Zhaoping HPP

Zhaoping Hydropower Plant had seen a great deal of bamboo, wood and consumer waste accumulating in front of the intake trash rack during flood season without effective cleaning measure, which had affected the safe operation of Zhaoping HPP. After on-the-spot investigation, a comprehensive comparison and analysis were conducted for the trash cleaning equipment in present China, a series of improvement measures was taken for the rotary trash cleaner in the course of technical upgrade. With the large garbage of bamboo and wood etc. usually seen at the low-head runoff HPP being effectively cleaned away, the harm on hydraulic structure and generator units resulting from too high pressure difference before and after trash rack is avoided.
