Problems solved by technology

As a result, a large amount of low-temperature heat energy may be discharged to the environment during the condensation process, and since the latent heat of vaporization of the working fluid is much higher than the specific heat capacity, the thermal efficiency of this method is low

Abstract

The invention discloses a system for driving a liquid working medium to act through steam pressure belong to the technical field of steam turbines, and provides a new system for driving the liquid working medium to act with the steam pressure as power to effectively improve the heat efficiency. The system comprises an acting device, and further comprises a guide channel; the guide channel includes a steam cavity and a liquid cavity communicated with each other; the steam cavity is positioned above the liquid cavity; the guide channel is provided with a working medium inlet communicated with the steam cavity, and a working medium outlet communicated with the liquid cavity; the acting device is connected with the working medium outlet; and a cooling device for cooling the working medium is arranged between the working medium inlet and the working medium outlet in the guide channel. As the process of converting high-temperature and high-pressure steam from a gas state to liquid is before acting of the high-temperature and high-pressure steam, the vaporization latent heat of the gas-state steam working medium is not discharged in the environment, the total heat efficiency can be greatly improved, and the acting device is effectively protected.

Description

technical field [0001] The invention relates to the technical field of steam engines, in particular to a system for driving a liquid working medium to do work through vapor pressure. Background technique [0002] So far, most of the devices for doing work or generating electricity have achieved the purpose of doing work or generating electricity by forming high-temperature and high-pressure gas, and then expanding the high-temperature and high-pressure gas. There are generally two ways to form high-temperature and high-pressure gas: one is to make combustible fuel react with oxygen in the air, and directly form high-temperature and high-pressure gas through combustion; the other is to heat the liquid working medium by burning the fuel, such as Water evaporates the liquid working medium to form high-temperature and high-pressure gas, such as internal combustion engines, gas turbines, steam engines, etc. [0003] Among them, by heating the liquid working medium, the liquid wo...
