Isothermal compression type heat engine

Abstract

The invention relates to an isothermal compression type heat engine taking air as a thermodynamic working medium. The heat engine is technically characterized in that an isothermal air compressor is employed to replace a heat insulation air compressor, two engineering links, i.e. air compression and expansion working are performed in different engine components separately so as to substantially improve the heat engine working pressure, and a temperature gradient type heat preservation composite pipe is arranged to efficiently recover and utilize the tail gas waste heat, thereby obviously improving the thermal efficiency of the heat engine. When necessary, the isothermal air compressor and a low-temperature refrigeration instrument are used cooperatively to make toxic and harmful gas components in tail gas automatically condense and liquefy under an artificial low temperature environment and make them separated from clean gas, and then the toxic and harmful gas components are collected to serve as chemical raw materials, thereby realizing zero emission of toxic and harmful substances in engine tail gas and zero pollution.

Description

Technical field [0001] The invention relates to a heat engine, in particular to a process method and device of an isothermal compression heat engine with air as a heat working medium and the heat efficiency is significantly improved. Background technique [0002] At present, the heat engine using air as the heat working medium usually adopts adiabatic compression air compression method; especially the piston type internal combustion engine, for a long time, the two different engineering links of air compression and expansion work in the engine are placed in the same cylinder In the process of air compression, the mechanical work consumed in the engineering process of air compression is large and the working pressure cannot be increased. At the same time, the exhaust heat recovery rate of the heat engine is low, and the utilization efficiency is extremely low. The toxic and harmful substances in the tail gas are discharged into the natural space freely; this leads to low heat engi...
