Problems solved by technology

Waste heat in various industries has the characteristics of high temperature, high pressure, and high energy. If it is directly discharged into the atmosphere, a large amount of heat will be wasted, and it will also bring greater pressure to the already serious global greenhouse effect.

Abstract

The invention discloses a waste heat power generation system with a conical rotor. The waste heat power generation system is formed by acting working medium, a heat exchanging device and an electrical system, wherein the acting working medium is organic working medium; the conical rotor can be in a bearing-contained structure or a bearing-free structure; when the conical rotor is in a bearing-container structure, a radial turbine expansion machine produces axial tension FR opposite to a direction of electromagnetism axial force FL produced by the conical rotor of a generator coaxially coupled with the radial turbine expansion machine; the FL adjust with changes of FR and can be fully counteracted; when the conical rotor is in a bearing-free structure, a power winding set and a suspension winding set are embedded into a stator of the generator at the same time and the rotor of the generator and the coaxial radial turbine expansion machine can suspend; and a bearing-free effect can be achieved, and power winding set actions can be considered at the same time. The power generation system is characterized by simple structure, long maintenance period and high efficiency; upon the bearing-free structure, purity of the action working medium of the power generation system can be guaranteed, so service life of the system can be prolonged.

Description

technical field [0001] The invention belongs to the field of waste heat utilization and recovery of a novel waste heat power generation system, in particular to a waste heat power generation system with a conical rotor generator which is suitable for an expander to generate large axial tension and has a bearing or no bearing structure. Background technique [0002] Energy shortage is a global problem, which has attracted people's attention day by day. It is also the main problem restricting the sustainable development of various energy-consuming industries. Waste heat in various industries has the characteristics of high temperature, high pressure, and high energy. If it is directly discharged into the atmosphere, a large amount of heat will be wasted, and it will also bring greater pressure to the already serious global greenhouse effect. Contents of the invention [0003] The purpose of the present invention is to provide a waste heat power generation system with a conic...
