Anti-mist high-efficient evaporative mixed-flow condensing method and condenser

Abstract

The invention discloses an anti-mist evaporative mixed-flow condensing method and a condenser, the mixed-flow condensing way of arranging an anti-mist region at the upper part, arranging a main condensing region at the middle part and arranging an auxiliary condensing region at the lower part is adopted, exhaust of a steam turbine is respectively sent into a downstream pipe bundle (20) of the main condensing region and the downstream pipe bundle (17) of the anti-mist region by adopting two steam distribution pipelines, and the running is carried out according to the steam and water downstream way; and an upstream pipe bundle (22) of the auxiliary condensing region runs according to the steam and water upstream way. The anti-mist high-efficient evaporative mixed-flow condensing method adopts the high-efficient heat exchange mechanism of latent heat exchange, thereby leading the heat exchange effect to be not affected by the temperature of an environmental dry ball, leading the latent heat of evaporation of water to be great, meeting the heat exchange need by using small circulation quantity, realizing high efficiency, low condensation back pressure and low water consumption, and eliminating the mist phenomenon formed by evaporation of a water film. The heat exchange method and the condenser are applicable to power, petrochemical industry, metallurgy, refrigeration and other fields.

Description

technical field [0001] The invention relates to the technical field of exhaust steam condensation, in particular to an anti-white mist evaporation mixed-flow steam condensation method and a condenser. Background technique [0002] At present, the process of producing electric energy in a condensing power plant is a process of energy conversion, that is, the chemical energy of the fuel converts water into saturated steam through the boiler 1, and the saturated steam becomes superheated steam after being superheated by the heater 2, and the superheated steam in the steam turbine In 3, the expansion works, the heat energy of the steam is converted into mechanical energy, and the mechanical energy is finally converted into electrical energy through the generator 4. The low-pressure saturated steam after expansion work—the exhausted steam is condensed into condensed water through the condenser system 5, and then sent to the condensed water treatment system by the condensed water ...
