Abstract

The invention relates to a vertical permanent-magnet suspension waste-heat power generator which comprises a power generator outer shell, an expander volute, a power generator impeller, a power generator rotating shaft, a stator system, a rotor system, an upper bearing part and a lower bearing part, wherein the expander volute is mounted on the power generator outer shell; the power generator impeller is connected with a power generator rotating shaft; the power generator rotating shaft is connected with a power generator rotor arranged in the rotor system, and supported by the upper bearing part and the lower bearing part; the upper bearing part and the lower bearing part are fixed on the power generator outer shell; a power generator stator arranged in the stator system is fixed on the power generator outer shell; an air gap is formed between the power generator stator and the power generator rotor; and high-temperature steam of waste-heat resources is absorbed by the expander volute, the power generator impeller is pushed to rotate, and then the vertical permanent-magnet suspension waste-heat power generator is driven to generate power. The vertical permanent-magnet suspension waste-heat power generator provided by the invention is reasonable in design, compact in structure and reliable in running; by utilization of the permanent-magnet suspension bearings which are free from oil lubrication, little in abrasion, long in life, and capable of running at high rotating speed, the supporting function is achieved; the vertical permanent-magnet suspension waste-heat power generator is cooled by adopting a cooling water injection mode; the waste-heat resources in a factory can be sufficiently utilized; the environmentally-friendly and energy-saving effects are achieved; and the market application prospect is broad.

Description

technical field [0001] The invention relates to a vertical permanent magnetic levitation waste heat generator, which is mainly used in the field of generators. Background technique [0002] Magnetic suspension bearing is a high-performance bearing that uses the magnetic force generated by permanent magnets or electromagnets to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. Compared with traditional mechanical bearings, it has the advantages of low wear, low energy consumption, high speed, long life, no lubrication and no oil pollution, etc. It is especially suitable for high-speed, vacuum, ultra-clean and other special environments. It is used in energy transportation, military medical treatment , Aerospace and robotics and other high-tech fields have broad application prospects. As a kind of magnetic suspension bearing, the permanent magnetic suspension bearing completely relies on the permanent magnetic force or supe...
