The invention belongs to the technical field of condenser online cleaning, and relates to a steam turbine condenser online cleaning device and a using method thereof. A steam turbine is connected with a plurality of condensers, each condenser is provided with a cooling liquid inlet and a cooling liquid outlet, and each cooling liquid inlet is connected to a cooling liquid water inlet pipe through a cooling liquid inlet branch; a cleaning device comprises a water tank filled with chemical cleaning liquid; a liquid outlet of the water tank is connected with a main liquid inlet pipe, a dosing pump is arranged on the main liquid inlet pipe, the output end of the main liquid inlet pipe is connected with a plurality of liquid inlet branch pipes, each liquid inlet branch pipe is connected with a cooling liquid inlet branch, and a valve is arranged on each liquid inlet branch pipe; and a liquid return opening of the water tank is connected with a main liquid outlet pipe, the input end of the main liquid outlet pipe is connected with a plurality of liquid outlet branch pipes, each liquid outlet branch pipe is connected with a cooling liquid outlet branch, and a valve is arranged on each liquid outlet branch pipe. It is achieved that the cleaning device can independently clean one condenser, other condensers can work normally, and operation of a steam turbine system is not affected.
Description
technical field [0001] The invention belongs to the technical field of on-line cleaning of condensers, and in particular relates to an on-line cleaning device for a steam turbine condenser and a method for using the same. Background technique [0002] In the normal production process of the power plant, there are strict standards for the temperature control of various working fluids. In order to meet the requirements of the production process, it is necessary to add heat exchange devices to each system, oil coolers in the oil system, steam turbine condensers, All through the reverse and downstream exchange of cold and hot media to achieve the purpose of controlling the temperature of various media. [0003] Since the cooling water of the condenser comes from the circulating water, due to the long-term operation, the influence of the water quality results in serious scaling on the tube wall of the condenser, which greatly affects the vacuum of the unit, and the direct consequ...
