Abstract

An axial-flow type jet flow gas wave pressure supercharger relies on operation of pressure wave to achieve energy exchange between high-pressure gas and low-pressure gas, avoids mixed diffusion energy loss and has the advantages of being high in isentropic efficiency, low in rotation speed, capable of working with fluid and the like. A pressure oscillation tube channel with variable rectangular cross section is adopted to reduce incident loss and flow loss of jet flows. A pressure equalizing port is arranged in the pressure supercharger so that performance of different pressure ratios is balanced. A pressure expansion fluid director is arranged at the position of a compression fluid outlet to effectively convert air flow kinetic energy. The axial-flow type jet flow gas wave pressure supercharger can fully utilize pressure energy in the production process and stratal pressure energy such as natural gas and can serve as an efficient device for effectively utilizing the pressure energy.

Description

technical field [0001] The invention discloses an axial-flow jet gas wave supercharger, which belongs to the technical field of realizing supercharging by gas jet flow. Background technique [0002] The comprehensive utilization of gas pressure energy has important economic and social benefits. In terms of using high-pressure gas expansion to do work to compress low-pressure gas, commonly used equipment includes expander-compressor units, turbochargers and ejectors. Turbines and turbochargers rely on impellers to transfer energy, have complex structures, high rotation speeds and are difficult to operate with liquid. Although the injector has the characteristics of no rotating parts and simple structure, its efficiency is very low, only more than ten percent. Contents of the invention [0003] The invention provides a high-efficiency, low-speed and liquid-carrying gas jet supercharging device-an axial-flow jet gas wave supercharger. [0004] In the supercharger of the pr...
