Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the detailed description is presented by way of example only and is not intended to limit the utility model.
During normal operation of the air separation device, the air safety valve of the steam turbine uses the condensate of the steam turbine as a water seal to ensure normal operation of a vacuum system of the steam turbine, and the condensate of the water seal of the air safety valve keeps a small amount of overflow in order to ensure the effectiveness of the water seal. In the prior art, condensate overflowed by the water seal of the atmospheric safety valve is directly discharged into a sewage pipe network, so that the waste of energy is easily caused, and the difficulty in sewage treatment is also increased. Therefore, as shown in fig. 1, in this embodiment, an apparatus for recovering condensate overflowed from an atmospheric safety valve is provided, which includes an atmospheric safety valve drainage pipeline, an air compressor impeller flushing tank, a condensate recovery pump, and a condensate recovery pipe network, wherein the atmospheric safety valve drainage pipeline is connected to a sewage pipe network and the air compressor impeller flushing tank through a first branch pipeline and a second branch pipeline, respectively, and a stop valve V1 and a stop valve V2 are respectively provided on the first branch pipeline and the second branch pipeline;
The condensate recycling pipeline is connected with the condensate recycling pipe network, an inlet valve V3, a condensate recycling pump and an outlet valve V4 are sequentially arranged on the condensate recycling pipeline at intervals along the flowing direction of liquid in the condensate recycling pipeline, the condensate recycling pipeline is connected with the condensate recycling pipeline, a connecting point is located between the inlet valve V3 and the outlet valve V4, and a reflux valve V5 is arranged on the condensate recycling pipeline.
In the recovery device, the stop valve V1 is in a normally closed state, the stop valve V2 is in a normally open state, condensate overflowing from the water seal of the atmosphere safety valve enters the flushing water tank of the impeller of the air compressor through the second branch pipe by virtue of the drainage pipeline of the atmosphere safety valve for recycling, when the liquid level in the flushing water tank reaches 80%, the inlet valve V3, the outlet valve V4 and the reflux valve V5 are opened, the condensate recovery pump is started, the reflux valve V5 is gradually closed to the pump of the condensate recovery pump, and then the water pressure is reduced to 0.5Mpa, so that the condensate is sent into the condensate recovery pipe network. When the liquid level in the flushing tank is lower than 20%, the condensate recovery pump is stopped. When the device stops working, the stop valve V2 can be closed, the stop valve V1 is opened, and a small amount of condensate remained in the pipeline is discharged into a sewage pipe network.
When in actual use, the overflow condensate of the atmosphere safety valves of the plurality of air separation devices is converged into the drain pipeline of the atmosphere safety valves, and meanwhile, the recycling of the overflow condensate of the atmosphere safety valves of the plurality of air separation devices is realized, the treatment pressure of a sewage pipe network is reduced, and meanwhile, the utilization rate of the condensate is improved.
In this embodiment, a liquid level meter is disposed in the air compressor impeller flushing water tank. Specifically, the level gauge includes a remote level gauge and an in-situ level gauge.
The remote liquid level meter and the on-site liquid level meter are arranged in the impeller flushing water tank of the air compressor, and the liquid level of the flushing water tank is monitored in real time, so that the starting time and the frequency of the condensate recovery pump are determined. The problem of equipment damage caused by insufficient water quantity at the inlet of the condensate recovery pump due to the fact that the liquid level is not monitored, and the liquid level of a flushing tank is low when the condensate recovery pump is started is avoided. Meanwhile, in order to facilitate liquid level monitoring and convenient observation and operation of field staff, an on-site liquid level meter and a remote transmission liquid level meter are arranged, the on-site liquid level meter facilitates observation and operation of the field staff, and the remote transmission liquid level meter facilitates remote monitoring of the liquid level of the flushing water tank by a central control staff.
In this embodiment, a pressure gauge P is disposed on the condensate recovery pipe, and the pressure gauge P is located between a connection point between the condensate reflux pipe and the condensate recovery pump. The arrangement of the pressure gauge can more intuitively acquire the post-pump water pressure of the condensate recovery pump.

The utility model provides an atmospheric relief valve overflow condensate recovery device, which is used for collecting condensate into an air compressor impeller flushing water tank as flushing liquid to realize recovery and utilization of the condensate.
