Precise condenser rubber ball cleaning device and method, and condenser

Abstract

The invention discloses a precise condenser rubber ball cleaning device which comprises a portal frame, a propulsion device, a ball filling device and a driving device, wherein the portal frame is fixed in a condenser water chamber; the propulsion device is movably arranged on the portal frame through a guiding device and can move forward and backward in the condenser water chamber; the ball filling device is arranged on the propulsion device and communicates with a rubber ball pump arranged outside the condenser water chamber through a ball filling servo pipe; the ball filling device uniformly fills a plurality of rubber balls into a row of or a plurality of rows of heat exchanging pipes in the condenser water chamber; and the driving device is connected with the guiding device to enablethe propulsion device to do up-down reciprocating motion in the condenser water chamber. Through cooperation of the propulsion device and the ball filling device, a plurality of rubber balls are uniformly filled into a row of heat exchanging pipes in the condenser water chamber, so that the cleaning coverage rate is increased to above 90% from 42%, the design value of the condenser cleaning rate is kept for a long time, and energy conservation and emission reduction are realized.

Description

technical field [0001] The invention belongs to the field of condenser cleaning, and in particular relates to a precise cleaning device and cleaning method for condenser rubber balls. Background technique [0002] The rubber ball cleaning device is a special equipment for cleaning the cooling pipe of the condenser during the operation of the steam turbine generator set, and it can be cleaned without stopping the machine. The performance of the device directly affects the cleanliness and heat transfer efficiency of the condenser. It is an indispensable equipment to improve the economy of the power plant and ensure the safe operation of the condenser. However, due to the unreasonable design of the previous rubber ball cleaning device, especially the way of delivering the ball, the cleaning coverage rate of the rubber ball is only 42%, which cannot achieve the cleaning effect and purpose at all. The cleaning rate of the condenser is always low. The headache of each power plan...

However, due to the unreasonable design of the previous rubber ball cleaning device, especially the way of delivering the ball, the cleaning coverage rate of the rubber ball is only 42%, which cannot achieve the cleaning effect and purpose at all, and the cleaning rate of the condenser is always low. The headache of each power plant is also the reason why each power plant does not mention the online cleaning rate data of the condenser
