Multipoint centralized ball release system of the rubber ball cleaning in the condenser

摘要

A rubber ball cleaning multipoint centralized ball serving system for a condenser includes a condenser water chamber (1), a cooling water outlet pipe (18), a cooling water inlet pipe (3), a ball recovery net (16), a second isolating valve (18), a rubber ball pump (13), and a check valve (12). A water inlet end of the condenser water chamber (1) is connected to a plurality of pulse ball serving valves (2, 4, 5). The plurality of pulse ball serving valves (2, 4, 5) is connected to a ball adding chamber (9) via a rubber ball transfer pipe (6). The rubber ball transfer pipe (6) is connected to the cooling water inlet pipe (3) via another pulse ball serving valve. The ball adding chamber (9) is connected to the circulating cooling water outlet pipe (18) via a hot water discharging pipe (20). The hot water discharging pipe (20) is provided with a third isolating valve (17) and a hot water discharging valve (19). A lower portion of the ball adding chamber (9) is provided with a rubber ball discharge valve (10). The present system can reduce a quantity of the circulating cooling water that is heated during running of the rubber ball system and again enters the water inlet pipe of the circulating cooling water system, thereby improving a condenser circulating cooling effect. By oppositely and correspondingly operating a pulse ball serving valve (5) and a hot water discharging valve (19) to open or close, a great number of rubber balls are enabled to centrally enter the circulating cooling water inlet pipe (18) and the condenser water chamber (1) within a short time, thereby cleaning the condenser heat exchange pipe in full coverage.
