Abstract

The invention relates to a vacuum steam recovery device for a steam turbine, comprising a closed dead steam recovery tank and an efficient jet pump, wherein, the efficient jet pump is arranged in a vertical manner, and the bottom of the closed dead steam recovery tank is connected with a high pressure pump; an outlet of the high pressure pump is connected with a jet pipeline; a jet outlet of the efficient jet pump is connected with an inlet of the closed dead steam recovery tank, and a jet inlet is connected with an outlet of the jet pipe; and a suction inlet is connected with a dead steam outlet of the steam turbine by a fan, and the closed dead steam recovery tank maintains enough pressure which can transform at least part of dead steam into liquid water. The device assures differentialpressure of the steam turbine, and meanwhile recovers the dead steam of the steam turbine with pressure difference generated by each equipment and self drop height of the efficient jet pump as power,thus effectively utilizing heat energy in the dead steam, and avoiding thermal pollution; and the device can be mainly applied to various occasions provided with the steam turbine.

Description

technical field [0001] The invention relates to a steam turbine vacuum steam recovery device, which is mainly used in various occasions with steam turbines. Background technique [0002] In order to maximize the work, the end of the existing steam turbine is equipped with a condenser and various forms of cooling towers to cool the exhaust steam at the end of the steam turbine, turning it into condensed water and discharging it to greatly reduce Small volume, forming a negative pressure at the end of the steam turbine to greatly increase the pressure difference between the front and back of the steam turbine. This technology of increasing the pressure difference of the steam turbine wastes a lot of water resources, and the latent heat of the exhaust steam of the steam turbine cannot be utilized, wasting a lot of heat energy. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steam turbine v...
