Shock wave compressor

Abstract

The invention discloses a shock wave compressor and belongs to the technical field of air compression. The shock wave compressor comprises a rotating stamping rotor, a blade diffuser and a pressurization volute. A plurality of gas flow channels are arranged on the edge of the rotating stamping rotor, each gas flow channel is internally provided with a shock wave induction block, the front section of the shock wave induction block is provided with a slope, a plane is positioned at the rear of the slope, and a reflecting curved surface corresponding to the shock wave induction block is positioned in the gas flow channel. The rotating stamping rotor rotates at a high speed to form supersonic air flow, the supersonic air flow generates oblique shock waves at the front end of the slope and forms normal shock waves after multiple reflection through the reflecting curved surface and the slope; the oblique shock waves formed by the supersonic air flow at the front of the reflecting curved surface are subject to interference of the normal shock waves, and a shock wave wall is formed near the normal shock waves. The shock wave wall is utilized to boost gas pressure and reduce air flow speed, so that the compression efficiency is improved, and the high compression ratio is achieved. Besides, the rotating stamping rotor is simple in structure and convenient to process and manufacture.

Description

technical field [0001] The present invention relates to a compressor, more specifically, to a compressor that utilizes shock wave characteristics to increase gas pressure, which can be called a shock wave compressor. Background technique [0002] Traditional compressors usually increase the pressure through the volume change of the working volume, and also increase the pressure through the conversion of kinetic energy and potential energy by increasing the speed. Traditional compressors have low operating efficiency, complex structures, many moving parts, and high maintenance costs. [0003] At present, some new types of compressors have appeared. These compressors use the principle of shock waves to compress air. They are generally called supersonic compressors or shock wave compressors. Compared with traditional compressors, shock wave compressors operate The efficiency is higher, and the shock wave compressor has its incomparable advantages under the condition of high si...
