Description

A rubber ball cleaning system with a ball collecting and counting device

technical field

The invention relates to the field of rubber ball cleaning devices for condensers or tubular heat exchangers, in particular to a rubber ball cleaning system for condensers in thermal power plants, which integrates the functions of recycling rubber balls and adding new balls. Rubber ball cleaning system with ball collection and counting device.

Background technique

The ball collection rate of the rubber ball system is an important basis for judging whether there are problems such as rubber ball blockage in the condenser, ball leakage due to lax collection nets, and blockage of the ball collection port. Therefore, the ball collection rate should be counted frequently, but the required accuracy Not high, the volume is used to estimate the number of rubber balls, and the deviation does not exceed 100. For the base of 2000 rubber balls, the calculation requirements can be met, and if the balls are counted manually, the accuracy will not be very high due to human factors.

As we all know, the conventional condenser rubber ball cleaning system has been used for many years, and there are some small upgrades, but the principle and operation mode are similar, requiring manual addition, collection and counting of balls. There are also some newly-built power plants that have adopted more advanced rubber ball cleaning devices, which can count rubber balls through special devices, but the investment cost of equipment is very high. Generally, the rubber ball system of power plants operates normally, and will not invest a lot of money in equipment transformation , so the current situation of heavy workload of operators has not been changed.

In addition, there is a ball-filling end cover on the top of the ball-filling chamber of the condenser rubber-ball cleaning system. After the balls are loaded, the ball-filling system can be operated, but the balls can only be received in the ball-filling room. After counting the number of rubber balls and calculating the ball collection rate, they can only be put into the net pocket at the drain outlet through the drain door installed at the outlet pipe of the balling room. After manually counting the balls, isolate the rubber ball cleaning system and open the balling room to load the balls. After adding old balls and supplementary new balls to the mouth, the recovery system will run again. The operation steps are cumbersome and the workload of the personnel is heavy; repeated operations of adding balls to the ball chamber will cause the rubber seal to leak easily.

To sum up, improving the existing rubber ball cleaning system, reducing the transformation cost and realizing that after the rubber ball counting is completed, returning to the rubber ball system circulation is one of the topics to be studied by those skilled in the art. .
