Embodiment Construction

[0010] The present invention will be described in further detail below in combination with specific embodiments.

[0011] exist figure 1 Among them, the steam turbine blade fouling cleaning device includes steam turbine 1, which is connected to condenser 2, condensation pump 4, control valve A5 and condensate water system 6 in turn by pipeline 3, and is installed on the pipeline between control valve A and condensation pump The circulation pipe 8 is provided with a control valve B7 and a cleaning circulation system 9, one end of which is connected to a pipeline, and the other end extends into the regulating valve chamber of the steam turbine. Close the control valve A, fill the hot well of the condenser with cleaning liquid at about 80-90°C, open the control valve B, and start the condensation pump. The cleaning liquid enters the regulating valve chamber from the circulation pipe, and enters the steam turbine from the regulating valve hole. , Turn on the turning device for tu...

Abstract

The invention discloses a turbine blade scaling cleaning device, and belongs to turbine cleaning equipment. The device comprises a turbine; and the turbine is connected with a condenser, a condensation pump, a control valve A and a condensate system by pipes in sequence. The turbine blade scaling cleaning device is characterized in that a circulating pipe is arranged on the pipe between the control valve A and the condensation pump; a control valve B and a cleaning circulating system are arranged on the circulating pipe; one end is connected with the pipe; and the other end extends into an adjusting valve chamber of the turbine. The turbine blade scaling cleaning device shortens traditional at least three-day maintenance time to six hours, so that the maintenance time is largely shortened, and the working efficiency is improved; and the blade cleaning of the turbine has no need to open a cylinder, so that the maintenance intensity is reduced, the damage of spare parts from tool hammering, forced pulling and hard drawing is prevented, the equipment performance perfectness is guaranteed, and the potential safety hazard caused by opening the cylinder is eliminated.

Description

technical field [0001] The invention belongs to steam turbine cleaning equipment, in particular to a steam turbine blade fouling cleaning device and method used in small and medium-sized power generation and industrial steam turbine units. Background technique [0002] The steam of small and medium-sized steam turbines mainly comes from the superheated and saturated steam produced by small industrial boilers, waste heat boilers or gasification furnaces. Since small industrial boilers, waste heat boilers or gasification furnaces do not have strict requirements on water supply, the discharge control during operation is not standardized. , resulting in poor steam quality, high salt (alkali) content in the steam, these salt (alkali) parts are brought into the flow part of the steam turbine with the steam, and precipitate out as the pressure of the steam in the steam turbine decreases, Deposited in the flow part of the steam turbine, forming fouling of the turbine blades, reducin...
