Problems solved by technology
According to the design institute's design, the treatment method is to start the flushing water pump to backwash it with water. Due to the poor effect, especially when encountering broken resin and iron filings impurities or impurities with high density, manual cleaning is generally used, which requires at least 4 people and 36 hours , both labor-intensive and time-consuming

Description
technical field [0001] The present invention relates to a water gas backwashing device and method for condensate fine treatment tree traps, in particular to a water vapor backwash device and method for condensate fine treatment tree traps in thermal power plants, belonging to condensate polishing treatment in thermal power plants The technical field of tree trap water vapor backwashing operation. Background technique [0002] Units above 300MW in thermal power plants must have a condensate polishing system due to water quality requirements, but supercritical units above 600MW require full filtration of condensate due to extremely strict water quality requirements. The safe and normal operation of condensate polishing is directly related to the economic interests of thermal power plants and the safe operation of units, especially newly built units. The function of the resin trap in the condensate polishing system is mainly to prevent resin leakage and intercept broken resin....
