Descaling system for condenser cooling tubes

摘要

A descaling system for condenser cooling tubes having numerous descaling elements consisting of sponge balls forced through said cooling tubes, wherein a vessel for receiving said descaling elements to soak them with cooling water is fitted with a cage member which is designed to allow the passage of cooling water along and provided at the bottom with a pipe communicating with a 3-port switching valve; the 3-port switching valve is connected to the end of a feed pipe for delivering descaling elements to a cooling water circulation line and that of a discharge pipe for drawing out used descaling elements; and these feed and discharge pipes are made to communicate with the cage member according to the selective operation of the 3-port switching valve.
