Problems solved by technology
[0003] Traditional waste heat power generation usually uses the combination of an expander and a generator to generate power, with a low degree of integration, and the traditional expander is driven by gears, which will cause gear wear and bearing wear, and the power transmission to the generator is carried out by the coupling. And there is an oil pump, which requires the application of a bearing lubrication system. The system efficiency is low, the maintenance cost is high, and it is not easy to use

The invention discloses a novel magnetic suspension waste heat turbine generator. The generator comprises a fan cover, a shell and an end cover. The generator is characterized in that a turbine is arranged in the fan cover; a permanent magnet motor ring, two magnetic suspension bearings and a rotating shaft are arranged in the shell; a wiring end is arranged at the top of the end cover; each magnetic suspension bearing comprises a stator magnetic conductive ring, a rotor magnetic conductive ring, a permanent magnet ring, a stator lamination layer and a rotor lamination layer; the permanent magnet motor ring comprises a stator, a rotor and a coil, wherein the coil is wound on the inner wall of the stator. According to the novel magnetic suspension waste heat turbine generator, the magnetic suspension bearings are adopted to replace a traditional bearing mode. The novel magnetic suspension waste heat turbine generator is characterized in that gear-free direct drive is achieved, equivalent, gear abrasion and bearing abrasion are avoided, coupling loss is avoided, an oil pump and a bearing lubricating system are avoided, and therefore, the system has the advantages of improved efficiency, prolonged service life, reduced maintenance cost and high cost performance in the life cycle.
Description
technical field [0001] The invention relates to the technical field of waste heat power generation equipment, in particular to a novel magnetic levitation waste heat turbine generator. Background technique [0002] Every year, 20 million hectares of forests disappear from the earth, and more than 13 billion tons of carbon dioxide are emitted into the atmosphere every year, a large part of which is industrial waste gas. Organic rankine cycle power generation technology (ORC, Organic Rankine Cycle) can efficiently recover medium and low temperature waste heat resources (below 350 ℃, low pressure or normal pressure) which is of great significance for improving my country's energy utilization rate, energy conservation and emission reduction, and environmental protection. [0003] Traditional waste heat power generation usually uses the combination of an expander and a generator to generate power. The degree of integration is low, and the traditional expander is driven by gears, ...
