Background
The shaft seal heater is a device for extracting a steam-water mixture of a steam seal system of a steam turbine, preventing steam from leaking from an end part steam seal to a machine room and a bearing extraction system, the extracted steam-water mixture enters the shaft seal heater, is cooled and condensed into water through shaft seal heating, and residual gas which is not condensed is discharged to the atmosphere through a shaft plus fan, so that in order to ensure that recovered shaft seal return steam can be fully condensed in the shaft seal heater, the shaft seal heater is kept in a micro negative pressure state in operation, the negative pressure value is kept at about 6KPa, and the pressure difference between the negative pressure value and the actual negative pressure value of the operating condenser is kept at 10 meters, so that the condensed water of the shaft seal heater is fully pumped into the operating condenser smoothly through the multistage water seal of the shaft seal heater, and meanwhile, the external air is prevented from entering the condenser, the effect of the multistage water seal of the shaft seal heater is maintained, the normal operation water level of the shaft seal is protected, but in actual operation, the operation working condition of the condenser is always changed, and the vacuum in the condenser is also constantly changed, so that two consequences are easy to occur in the multistage water seal operation of the shaft plus the shaft seal: (1) The drain backwater of the shaft seal heater is unsmooth, so that the shaft seal heater is easy to fill water, and potential safety hazards are brought to an operation unit. (2) The sealed water column in the multistage water seal can not be formed, so that the multistage water seal is similar to the dummy, a large amount of air is caused to enter the condenser, and the economic operation of the unit is affected.
At present, the multistage water seal in the application of the power plant is made of opaque metal materials, the formation condition of the operation sealing water column in the multistage water seal under different operation conditions cannot be observed in operation, whether the operation multistage water seal works normally or not is judged visually, the abnormal operation state is not analyzed and judged visually, a large amount of outside air in the actual operation multistage water seal enters the condenser and cannot be judged by staff, the economy of the operation unit of the power plant is obviously deteriorated, the vacuum value of the operation unit is obviously reduced, and a large amount of economic loss is caused to the power plant.
