Abstract

The invention relates to an expansion machine based on the rotation volume type. The expansion machine based on rotation volume type mainly comprises a shell, a shell end cover A, an auxiliary driving wheel, a shell end cover B, a dynamic wheel, a combined seal B, a main driving wheel end cover, a main driving wheel, a main driving wheel end cover A, a combined seal A, an exhaust port A, an auxiliary driving wheel groove, an air inlet B, an exhaust port B, a main driving wheel protrusion and an air inlet A. A timing device, the main driving wheel protrusion and the auxiliary driving wheel commonly form the sealed element volume surrounding the main driving wheel. Inverted-Y-shaped synchronous gear driving the main driving wheel and the timing device to rotate synchronously are arranged outside the shell. The main driving wheel is provided with the two air inlets and the two exhaust ports. The timing device is provided with two air ports, when the air ports of the timing device are overlapped with the air inlets of the main driving wheel, high-temperature and high-pressure gas enters the element volume, and the time of the suction process of the high-temperature and high-pressure gas working medium is relatively short.

Description

technical field [0001] The invention relates to the field of expanders, in particular to an expander based on a rotary volumetric type. Background technique [0002] Since the 19th century, many scholars have been constantly developing and supplementing the research on expanders. At present, expanders have been widely used in power generation in power plants, waste heat recovery and power machinery, and industrial low-temperature waste heat power generation. At the same time, many different types of expanders have been produced, such as piston expanders, turbo expanders, and scroll expanders. Among them, the turbo expander and the piston expander have the longest history. They were mainly the key equipment for obtaining low temperature before. Unless the technology of piston expander and turbo expander is developed rapidly, there are also such types of expanders on the market, which are mainly used for (1) natural gas pipeline pressure difference power generation, (2) Natu...
