Problems solved by technology

[0002] The steam turbine vacuum steam recovery system in the prior art mainly uses a steam-water circulation system composed of a steam turbine, a condenser, a deaerator and a cooling tower to realize the recovery and utilization of water resources in the vacuum steam and the discharge of waste heat. Although the steam recovery system can effectively recover the water resources in the vacuum steam for reuse, a large amount of industrial waste heat carried in the vacuum steam is directly or indirectly discharged into the atmosphere, wasting a lot of heat energy and causing thermal pollution to the environment

Abstract

The invention relates to a vacuum steam heating and pressurizing recycling device for a steam turbine, which comprises a recovery tank and a jet pump, wherein the recovery tank has a jet pipe and a drainage pipe; the jet pipe has a high-pressure pump; the jet outlet of the jet pump is connected with the inlet of the recovery tank through a pipe, the jet inlet of the jet pump is connected with the jet pipe, and the suction entrance of the of the jet pump is connected with a steam discharge pipe of a condenser through a steam inlet pipe; and the drainage pipe is connected with a deaerator. In the invention, the vacuum steam and condensed water generated after the vacuum steam passes through a condenser are sucked into the recovery tank under the suction action of the jet pump, and the condensed water is heated and pressured in the recovery tank and then delivered to the deaerator; and thus, the heat needed to be absorbed by the condensed water to be heated to a saturated temperature in the deaerator is reduced, the water resource and heat in the vacuum steam are recovered and recycled, and the aims of energy conservation and environment protection are fulfilled.

Description

technical field [0001] The invention relates to a steam turbine vacuum steam recycling device, in particular to a steam turbine vacuum stripping, warm-lifting, and pressure recycling device, which is used for recycling and reusing vacuum steam discharged from the steam turbine. Background technique [0002] The steam turbine vacuum steam recovery system in the prior art mainly uses a steam-water circulation system composed of a steam turbine, a condenser, a deaerator and a cooling tower to realize the recovery and utilization of water resources in the vacuum steam and the discharge of waste heat. Although the steam recovery system can effectively recover the water resources in the vacuum steam for reuse, a large amount of industrial waste heat carried in the vacuum steam is directly or indirectly discharged into the atmosphere, wasting a lot of heat energy and causing thermal pollution to the environment. Contents of the invention [0003] In order to overcome the above-me...
