Abstract

The invention discloses a power plant waste steam reutilization device comprising an oxygen remover, a waste steam recycling device, a boiler and a steam turbine. One side of the oxygen remover is connected with a supply water tank, and the other side of the oxygen remover communicates with the boiler. The boiler communicates with the waste steam recycling device, and the waste steam recycling device communicates with a waste steam discharging opening of the oxygen remover through an oxygen remover exhaust pipe. A water inlet port of the oxygen remover is further connected with a waste steam condensation pipe, the waste steam condensation pipe is connected with a condensing engine through a condensing water pump, the other end of the condensing engine is connected with the steam turbine, and the steam turbine communicates with a steam discharging opening of the boiler through a pipe. Targeted to the problem that oxygen removal waste steam and boiler continuous blowdown waste steam aregenerated in the operation process of an existing power plant, through the arranged waste steam recycling device, a plenty of waste steam discharged to the air and generated through the oxygen removerand the boiler continuous blowdown can be recycled and reutilized, the loss of a great amount of heat is avoided, and economic benefits of enterprises are increased.

Description

technical field [0001] The invention relates to the technical field of energy-saving equipment for power plants, in particular to a waste steam recycling device for power plants. Background technique [0002] At present, during the operation of the power plant, there will be deoxygenated exhausted steam and boiler continuous exhaust exhausted steam. First of all, during the operation of the power plant, it is necessary to pass 0.6-0.8Mpa steam into the deaerator to heat the feed water. During the heating process, the partial pressure of the water vapor on the water surface gradually increases, while the partial pressure of other gases gradually decreases, and the gas in the water Continuously separated from the water, a large amount of 0.2-0.3Mpa exhaust steam is discharged to the air through the electric valve of the oxygen removal head, causing a large amount of heat loss and noise pollution. Contents of the invention [0003] The purpose of the present invention is to ...
