Performance test and application study for environmentally friendly marine organism inhibitor in coastal power plants
摘要
Abstract
The breeding of marine mollusks in once-through cooling system of coastal power plants can not be effectively controlled using the conventional mechanical removal and organochlorine fungicide addition method.To solve this problem,this paper analyzes the advantages and disadvantages of the regular control methods for marine biology growth,and introduces the TRL-2004C environmentally friendly sea creatures inhibitor.The action mechanism of this TRL-2004C sea creatures inhibitor was presented,and its effectiveness was verified by the polluted marine biology performance test and micro marine biology performance test.Moreover,the application of the TRL-2004C sea creatures inhibitor in the once-through seawater cooling system was monitored.The results show that,after four years' application of this inhibitor dosing alternately with sodium hypochlorite dosing regimen,the marine fouling organisms inhibition rate reached up to 80％,and nearly no pollutant sea creatures was found in the cooling system.The occurrence of condenser tube blockage caused by shellfish growth didn't occur again.The heat transfer performance of the condenser titanium tube,closed loop cooler and vacuum pump cooler was improved,indicating a considerable economic benefit and social benefit.It provides an effective solution for pollutants control for marine organisms in once-through seawater cooling system.关键词
