Therefore, the rubber ball cleaning system used in mass production carries out on-line cleaning on the condenser cooling water pipe. The technology is basically perfect in the 50 s of the last century and is popularized and applied in a large quantity in the 90 s of the last century. However, the technology has the defects that the cleaning effect is not ideal, so that most of installed equipment is idle or abandoned, and the purposes of improving the cleanliness of the cooling pipe, improving the heat transfer performance and reducing the steam consumption of the steam turbine are not achieved.
The ball throwing pipe of the traditional condenser rubber ball cleaning system is a group of pipes, and rubber balls enter a circulating water system along with water flow and enter cooling pipes along with circulating water randomly, so that 100% of the cooling pipes cannot be cleaned;

Compared with the prior art, the invention has the following beneficial effects:
the invention adds the targeted positioning ball throwing device on the basis of the original rubber ball cleaning system, can accurately position the cooling pipe to be cleaned, can realize regional coverage and regional cleaning, and improves the cleaning efficiency. The sealing device can isolate ball throwing water from circulating water, so that the pressure in the ball throwing pipe can be higher than the pressure of the circulating water, and the rubber ball can smoothly pass through the cooling pipe to achieve the cleaning effect. According to the invention, 100% of cooling pipes are cleaned, and the rubber balls can be ensured to smoothly pass through the cooling pipes under a certain ball throwing pressure, so that the cleanliness of the cooling pipes is kept to be close to the design state, the heat exchange effect of the heat exchanger is improved, and the purposes of energy conservation and emission reduction are realized.
