Condensing steam turbine device

Abstract

The invention discloses a condensing steam turbine device, which comprises a steam turbine and a condenser, wherein the condenser specifically comprises a condensing chamber and a water collecting tank, the ground of the condensing chamber is of an outward convex arch structure, the top of the condensing chamber is fixedly provided with the condenser, a condensing pipe of the condenser penetratesthrough the condensing chamber and is fixedly arranged at the top end of the inner wall of the condensing chamber, the condensing chamber is fixedly connected with the water collecting tank through awater guide pipe, the bottom of the inner cavity of the water collecting tank is fixedly provided with a circulating water pump, the output end of the circulating water pump penetrates through and extends out of the water collecting tank, and two ends of the inner wall of the water collecting tank close to the top are provided with water level meters, and the condensing steam turbine device has the beneficial effects that the water vapor is efficiently and quickly condensed into water, then a circulation device is used for repeated circulation utilization, and the resources are saved.

Description

technical field [0001] The invention relates to the technical field of steam turbine mechanical equipment, in particular to a condensing steam turbine device. Background technique [0002] From a thermodynamic point of view, in the thermodynamic cycle of a modern large-scale power plant condensing steam turbine unit, the condenser acts as a cooling source, so it is an important part of the thermal cycle of the power plant, and as one of the important auxiliary machines of the condensing steam turbine unit First, its working performance directly affects the thermal economy and safety of the entire unit, among which the vacuum degree of the condenser, the subcooling degree of condensed water and the oxygen content are all very important influencing factors. [0003] First of all, from the perspective of cycle efficiency, the quality of the condenser vacuum, that is, the level of the final parameters of the steam turbine unit, has a very important impact on the cycle efficiency...

AI Technical Summary

Problems solved by technology

In a thermal system without feed water recuperation, every 7°C subcooling of condensed water is equivalent to a 1% reduction in the thermal economy of the unit

At present, many condensing thermal power generation units have the problems of low vacuum degree of condenser and large degree of subcooling of condensed water, which seriously affects the thermal economy and safety of unit operation.
