Steam turbine condenser based on process number transformable structure design

Abstract

The application belongs to the field of steam turbine condensers, and discloses a steam turbine condenser based on process number variable structure design, which comprises a horizontal shell and a plurality of heat exchange tube bundles; the left and right sides of the horizontal shell are respectively fixedly provided with a left mounting cylinder and a right mounting cylinder; in use, the cooling water flow change is directly converted into air pressure driving force through the air pressure adjusting mechanism, without an additional power source, so that the process number is automatically adapted; the structure is simple and the response is rapid; through the linkage cooperation of the actuator and the sealing assembly, the opening and closing of the outer circle heat exchange tube are switched, the cooling water flow demand under different loads of the steam turbine is adapted, the cooling water flows through the inner circle heat exchange tube to maintain high flow rate to prevent fouling when the load is high, all the heat exchange tubes are opened to recover waste heat by using the maximum heat exchange area and avoid cavitation when the load is low, and the operation stability and heat exchange efficiency of the condenser are significantly improved.
