The full-area rubber ball cleaning system comprises a ball serving device, a ball receiving device, a ball collecting device, a ball serving pump, a ball receiving pump, a first distributing device, a second distributing device, a main ball serving pipeline, a first ball serving pipeline, a second ball serving pipeline, a ball receiving pipeline, a ball serving device exhaust pipeline, a ball serving device drainage pipeline, a ball collecting device drainage pipeline, a ball collecting device blow-off pipeline and an electrical control cabinet, and the electrical control cabinet is provided with a programmable logic controller; the output end of the programmable logic controller is connected with the input end of a first program control valve, the input end of a second program control valve, the input end of a third program control valve, the input end of a fourth program control valve, the input end of a fifth program control valve, the input end of the ball serving pump and the input end of the ball receiving pump respectively; and the output end of the first program control valve, the output end of the second program control valve, the output end of the third program control valve, the output end of the fourth program control valve, the output end of the fifth program control valve and the output end of a differential pressure measuring unit are connected with the input end of the programmable logic controller.

Description

technical field [0001] The invention relates to a rubber ball cleaning system for the whole area of ​​a condenser. Background technique [0002] The rubber ball cleaning devices supporting four 330MW coal-fired steam turbine generator sets in a company are equipped with two ball collecting nets, two rubber ball pumps, two ball loading chambers and other pipeline valves and other equipment. Due to the different construction years of the units, there are two types of ball collection nets for the rubber ball cleaning device: the ball collection nets of #1 and #2 units are the earlier SL movable grid funnel-type ball collection nets, #3 and #4 The ball collection net of the unit is the current mainstream SF type movable grid shunt ball collection net. [0003] The function of the rubber ball cleaning device is to supply and assist the water flow to squeeze the sponge rubber ball (soft ball) through the condenser tube bundle during the operation of the unit, and to circulate con...
