Shock wave collision dual-supercharging-type wave pressure supercharger

Abstract

The invention discloses a shock wave collision dual-supercharging-type wave pressure supercharger, and belongs to the technical field of refrigeration and evaporation. According to the wave pressure supercharger, a shock wave and transmission shock wave dual-supercharging mechanism is utilized, and the high-pressure ratio of compressed gas is increased. A main machine body, an upper machine body and a lower machine body are connected through dual-end loose flanges. The main machine body comprises a main machine body shell and a rotary drum, the middle symmetric position of the main machine body shell is provided with supercharging gas outlets distributed evenly and circumferentially, shock wave collision tubes are evenly distributed on the rotary drum circumferentially, and the middle symmetric position of the rotary drum is provided with a square hole outwards. The upper machine body and the lower machine body are symmetrically arranged relative to the main machine body and are each provided with a detachable nozzle distribution disc, wherein high-pressure driving fluid nozzles and low-pressure expansion fluid nozzle outlets are distributed on the nozzle distribution disc periodically and circumferentially. According to the wave pressure supercharger, by the adoption of the shock wave collision principle, the gas supercharging effect is greatly improved due to a middle isosceles trapezoid supercharging fluid outlet, the temperature increasing effect is remarkable, the pressure reduction and temperature decrease effects are obvious due to two-side low-pressure expansion fluid outlet gas, the gas hot separation speed is high, the effect is good, the machine body size is small, and the wave pressure supercharger is portable and easy to maintain.

Description

technical field [0001] The invention relates to a shock wave collision double boost type gas wave supercharger, which belongs to a supercharging device that provides high-pressure gas that meets requirements for fields such as refrigeration and evaporation. Background technique [0002] At present, the gas supercharging devices used in the field of refrigeration and evaporation mainly include compressors, ejectors and conventional gas wave superchargers. [0003] The compressor rotates through a high-speed turbine to convert the kinetic energy into the pressure energy of the gas, so as to achieve the purpose of gas boosting. Since the pressurization effect of the compressor is greatly affected by the type of medium, such as when compressing water vapor, the efficiency of the compressor becomes very low, and the vacuum water vapor compressor has a large size in the evaporation field. The ejector ejects the low-pressure airflow through the high-pressure driving airflow, and ...
