Condenser rubber ball cleaning device

Abstract

The invention relates to a condenser rubber ball cleaning device. The device comprises a condenser A side ball collecting net plate and a condenser B side ball collecting net plate, the condenser A side ball collecting net plate and the condenser B side ball collecting net plate are connected with a ball collector, two ends of each unit ball collecting net plate respectively and correspondingly pass through each inlet door of each condenser small ball cleaning pump, are respectively converged, and then are respectively and correspondingly connected with input ends of a first condenser small ball cleaning pump and a second condenser small ball cleaning pump, output ends of the first condenser small ball cleaning pump and the second condenser small ball cleaning pump are respectively and correspondingly connected with an outlet door of each condenser small ball cleaning pump, an outlet door of each condenser small ball cleaning pump is connected with a branching device, the branching device is also connected with a ball loading chamber and an electric control cabinet, and the input ends of the first condenser small ball cleaning pump and the second condenser small ball cleaning pumpare also independently connected through a communication pipeline. Compared with the prior art, the cleaning device has the advantages of remarkably increasing the flow of circulating water in the cleaning device, improving the ball collecting rate, ensuring the cleaning of the pipe wall and the like.

Description

technical field [0001] The invention relates to the technical field of condenser rubber ball cleaning, in particular to a condenser rubber ball cleaning device. Background technique [0002] Generally, power plants use units 1 and 2 to operate and generate electricity. Units 1 and 2 are 600MW supercritical pressure, one-time intermediate reheat, single-shaft, four-cylinder, four-exhaust, and reactionary condensing steam turbine units; each unit It is necessary to clean the condenser rubber ball once a month to ensure the cleanliness of the titanium tube of the condenser and the heat exchange efficiency of the cold end. [0003] However, in the prior art, due to the arrangement of the circulation pump in the circulation pump room and the slight decrease in the output of one circulation pump after it has been changed to frequency conversion, the circulating water flow rate and flow rate of Unit 2 are lower than that of Unit 1. Due to the small flow rate during cleaning, the r...

Problems solved by technology

[0003] However, in the prior art, due to the arrangement of the circulation pump in the circulation pump room and the slight decrease in the output of one circulation pump after it has been changed to frequency conversion, the circulating water flow rate and flow rate of Unit 2 are lower than that of Unit 1. Due to the small flow rate during cleaning, the rubber balls cannot be recycled to the ball collector normally, and most of the rubber balls cannot even complete a cycle of cleaning. The temperature rise of circulating water decreases, reducing the economical operation of the unit; each side of the condenser rubber balls throws 1,000 balls each time, a large number of rubber balls escape, and the loss is huge
