Embodiment Construction

[0019] In order to realize the objectives, technical solutions and advantages of the embodiments of the present invention more clearly, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. The idea of ​​the present invention is to use the working fluid returned to the boiler 1 to cool the steam output by the steam turbine 2 and to heat the working fluid returned to the boiler 1 at the same time. Therefore, based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] In this embodiment, the superheater steam outlet of the boiler 1 is connected to the working ...

Abstract

A self-heat-absorption type heat exchanger combination belongs to the field of thermoelectric technology of a heat exchanger combination, is a combination of two heat exchangers and a refrigerator and is used for thermal power generation, nuclear power generation and exhaust steam heat power generation with media in closed circulation. According to the self-heat-absorption type heat exchanger combination, a working medium before a circulating pump absorbs the heat of a working medium behind the circulating pump to achieve absorption and reutilization of waste heat and improve the heat utilization rate; an external cold source is only used for cooling the last heat exchanger and carries away a little heat, the deposition of river water dirt is reduced to avoid cleaning of a steam condenser, and a low-temperature heater and a high-temperature heater are omitted; and the heat-electricity conversion efficiency is greatly improved.

Description

technical field [0001] The invention relates to a thermoelectric conversion device, in particular to a self-absorbing thermoelectric conversion device in which two or more heat exchangers and a cold pump are combined. Background technique [0002] The thermal power and nuclear power plants in use now use river water or cooling towers to provide low-temperature heat sources for steam turbines, dissipating a lot of heat energy, which is also the main reason why the efficiency cannot be improved, and causes thermal pollution, and consumes a lot of fuel and wastes a lot of energy. water resources. At the same time, the condenser needs to be shut down regularly to clean it. Contents of the invention [0003] The invention proposes a combination of self-absorbing heat exchangers aiming at the two major problems of waste and pollution in thermal power plants, nuclear power plants and waste heat power plants. [0004] The technical scheme adopted in the present invention is: ...
