Embodiment 1

[0021] Embodiment 1: In this embodiment, water vapor is used as the working medium, and the expander (2) adopts a steam turbine (2). The steam turbine (2) and the vapor-liquid separator (4) are evacuated by the vacuum pump (3): the steam generator (1) absorbs heat from the heat source to generate saturated water vapor with a pressure of 4MPa and a temperature of 250°C as the initial state ; After the saturated water vapor expands in the steam turbine (2) and does work to 2kPa and 17.5°C, it becomes exhausted gas containing saturated liquid, and the exhausted gas is divided into two parts: saturated liquid and saturated steam through the vapor-liquid separator (4); wherein the saturated steam After the ejector (11), the compressor (12) and the heat exchanger (13) restore the original state, and the saturated liquid is compressed by the compressed water pump (7) to increase to the initial pressure, and then through the heat exchanger (13) for heat exchange and The initial state ...

Embodiment 2

[0053] Embodiment 2: In this embodiment, water vapor is used as the working medium, the expander (2) adopts the steam turbine (2), and the heat exchange process of the heat pump is introduced on the basis of the embodiment 1. The steam turbine (2) and the vapor-liquid separator (4) are evacuated by the vacuum pump (3); the steam generator (1) absorbs heat from the heat source to generate saturated water vapor with a pressure of 4MPa and a temperature of 250°C as the initial state; After the saturated steam expands in the steam turbine (2) and does work at 2kPa at 17.5°C, it becomes exhaust gas containing saturated liquid, and the exhaust gas passes through the vapor-liquid separator (4) and is divided into two parts: saturated liquid and saturated steam; the saturated steam first Exchange heat with the heat pump (9) to raise the temperature to 80°C, and then restore the initial state through the ejector (11), compressor (12) and heat exchanger (13); the saturated liquid first e...

Embodiment 3

[0083]Embodiment 3: In this embodiment, water vapor is used as the working medium, and the expander (2) adopts a steam turbine (2). The steam turbine (2), evaporator (5), and vapor-liquid separator (4) are evacuated by the vacuum pump (3); the steam generator (1) absorbs heat from the heat source to generate a vacuum chamber with a pressure of 4MPa and a temperature of 250°C. Saturated water vapor is taken as the initial state; after the saturated water vapor expands in the steam turbine (2) and does work to 2kPa and 17.5°C, it becomes exhaust gas containing saturated liquid, and the exhaust gas is divided into saturated liquid and saturated steam through the vapor-liquid separator (4) Two parts; the saturated liquid evaporates into saturated steam at 2kPa and 17.5°C after absorbing heat from the cold source in the evaporator (5); the saturated steam returns to its original state through the ejector (11), and part of the initial saturated steam passes through the compressor (1...

Abstract

The invention is a steam thermal circulation for converting heat energy into useful work, comprising a course: after an expander does work on gaseous working medium in original state, the gaseous working medium becomes lean gas with liquid working medium (i.e. the content y of the liquid working medium in the lean gas is greater than 0), and after the lean gas is processed by steam-liquid conversion, the liquid working medium returns to original pressure by compression pump, and the steam or the lean gas returns to original pressure by a pressure recovery system composed mainly of a jet, and then returns to original temperature by heat pump, steam generator and superheater; and a thermal device for implementing the thermal circulation, comprises the following devices of: steam generator, superheater, expander, reheater, vaccum pump, condenser, evaporator, steam-liquid separator, heat pump, compressor and jet. And the invention has high efficiency, able to reach and exceed 100%, theoretically.

Description

technical field [0001] The present invention relates to a steam power cycle and device, in particular, to a steam power cycle and device for converting thermal energy into useful work. Background technique [0002] In order to convert thermal energy into useful work, thermodynamic cycles that have been proposed or applied include Otto cycle, Diesel cycle, Brayton cycle, Joule cycle, Stirling cycle, Erikson cycle, Carnot cycle, etc., and Rankine cycle belonging to steam power cycle, etc., there are also some mixed cycles such as binary steam cycle, gas-steam cycle, etc., and subsidiary cycles of the above cycles such as reheat cycle, regenerative cycle, etc. The adoption of the above-mentioned thermodynamic cycles has brought the development of mankind into the era of mechanical power and electric power. Due to theoretical limitations, these thermodynamic cycles and the thermal devices using these thermodynamic cycles have the disadvantage of low thermal efficiency, which di...
