Abstract

The invention discloses a radial-flow type fluidic pressure wave supercharger, which can realize the energy exchange between the high pressure gas and the low pressure gas by running the pressure wave, avoid loss of mixed and diffused energy and has the advantages of high isentropic efficiency, low rotating speed, operability with liquid, sufficient exhaust and on the like. For adopting a pressure oscillating tube channel with variable rectangular cross-section, the incidence loss and the flowing loss of the jet flow are reduced; the channel is a bending flow channel arranged along the radial radiation, the process of expanding and compressing is strengthened and the sufficient discharge of the compressed gas is accelerated by using the centrifugal force; pressure balancing holes are arranged in the machine, so that the performance is kept balanced at the different pressure ratios; a pressure expanding flow guider is arranged at a compressed gas outlet in order to transform the dynamic energy of the gas flow effectively. The radial-flow type fluidic pressure wave supercharger can fully utilize the pressure energy in the production process and the pressure energy in the stratums of natural gas, thereby providing an efficient device selection for utilizing the pressure energy sources effectively.

Description

technical field [0001] The radial jet air wave supercharger of the invention 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. The axial-flow jet booster also has the disadvantage that compressed gas is difficult to exhaust, and its axial dimension is relatively long. Contents of the invention [0003] The invention provides a high-efficiency, low-speed, li...
