Electric generating unit

Abstract

The invention relates to a unit for using intermediate-low temperature exhaust heat to generate electricity, comprising an intermediate-low temperature heat source, a generator, an absorber, a turbine, an electric generator, a solution pump and a connecting pipeline, wherein the connecting pipeline is communicated with the generator, the absorber, the turbine and the solution pump; the solution pump is connected with the generator and the absorber, delivers working substances from the absorber to the generator and sprays out the working substances by a spraying device in the generator; the generator is connected with the medium-low temperature heat source and heats mixing working substances by using the heat of the intermediate-low temperature heat source; the mixing working substances are heated to generate high-pressure steam for pushing the turbine to do work and drive the electric generator to generate electricity; and the steam after doing work on the turbine enters the absorber through the connected pipeline, and the evaporated solution in the generator also enters the absorber, cooled by cooling water in the absorber and delivered to the generator through the solution pump.The unit is energy-saving and environment-friendly, has simple structure and is easy to form modular production.

Description

【Technical field】 [0001] The invention relates to the field of power supply, in particular to a unit for generating electricity using medium and low temperature waste heat. 【Background technique】 [0002] At present, my country's energy utilization level is only 30%, and the rest is discharged into the environment in the form of medium and low temperature waste heat, which not only causes a huge waste of energy, but also brings a large amount of pollutant discharge. Therefore, with the depletion of fossil fuels and the severe environmental problems, the recovery and utilization technology of medium and low temperature waste heat has become an important topic in the field of energy conservation. [0003] At present, there is no such form of waste heat generator set, and the existing environmentally friendly generator sets mainly include solar thermal generator sets, air energy generator sets, and the like. However, these units have the following disadvantages: [0004] 1. T...
