A kind of low temperature heat energy machine

Abstract

A low-temperature heat energy machine includes a generator, a steam turbine, a heat energy collector, an evaporator, a condenser, a compression absorption heat pump, and a double-effect absorption heat pump. The compression absorption heat pump operates ， The low-temperature heat source energy is absorbed by the heat energy harvester, so that the low-temperature heat source generates high-level heat energy. The compression absorption heat pump drives the double-effect absorption heat pump to amplify and double the heat energy, and sends it to the evaporator to generate high-pressure gas that enters the steam turbine to expand and perform work. The steam turbine drives the generator to generate electricity. output. After the work done by the steam turbine, the low-pressure gas enters the condenser through the regenerator to be condensed into liquid, and the liquid passes through the regenerator through the solution pump and enters the evaporator for circulation. The gas in the condenser returns to the double-effect absorption heat pump cycle through the pipeline. The invention reduces the dependence of human beings on fossil fuels, is clean, environment-friendly, reduces emissions, can effectively curb global warming, and prolongs the life spans of human beings and the earth.

Description

technical field [0001] The invention relates to the technical field of resources and the environment, in particular to a low-temperature thermal energy machine which enables a low-temperature heat source to generate electric energy following the cycle principle of "Rankine" and "Carnot". Background technique [0002] At present, the vast majority of my country's electric energy is obtained by consuming raw materials and fuels. Other solar energy and wind energy have no continuity and mobility and are inconvenient to use. Therefore, my country's energy situation is still severe. Nearly 60-65% of industrial energy is converted into waste heat resources, of which low-temperature waste heat below 350 °C accounts for about 60% of the total waste heat, which is often accompanied by a large amount of low-temperature waste heat discharge, which cannot be realized by current technology Effective recycling. The invention follows the "Carnot" cycle principle to absorb heat from low-temp...
