The invention provides an opposite expansion wave superposition type self-driven supercharger and belongs to supercharging devices in the refrigerating and heating field. The supercharger makes use of an opposite expansion wave superposition mechanism, makes efficient use of heat energy and pressure energy of driving fluid, improves supercharging performance and has the self-driven characteristic. According to the supercharger, a main machine body is connected with an upper machine body and a lower machine body through flanges, the main machine body comprises a shell and an expansion wave superposition pipe revolving drum, a plurality of high-pressure driving liquid inlets distributed circumferentially and evenly and a plurality of low-pressure expansion fluid outlets distributed circumferentially and evenly are formed in the shell in a centering mode, expansion wave superposition pipes are circumferentially and evenly distributed on the expansion wave superposition pipe revolving drum, and skew surface transition square holes are formed in the centering position of the expansion wave superposition pipe revolving drum. The upper machine body and the lower machine body are symmetrically arranged relative to the main machine body and are each provided with a plurality of detachable nozzle combinations circumferentially and evenly distributed, and each detachable nozzle combination is composed of a supercharging fluid nozzle and a lower-pressure driven fluid nozzle. Through middle skew surface transition inlets, the revolving drum is driven to revolve, no driving machine is needed, sealing is good, and maintenance is easy. Low-temperature fluid expanded secondarily is discharged through the low-pressure expansion fluid outlets, and a temperature drop is large. Supercharging airflow is discharged through the supercharging fluid nozzles at two ends, and the supercharging effect is good.

Description

technical field [0001] The invention relates to a superimposed self-driven supercharger of opposite expansion waves, which belongs to refrigeration and supercharging devices that meet the requirements of refrigeration, heat pump and other fields. Background technique [0002] At present, the gas pressurization and refrigeration devices used in refrigeration, heat pump and other fields mainly include conventional air wave superchargers. [0003] Conventional air wave superchargers use high-pressure driven airflow to exchange energy through direct contact with low-pressure airflow, and use unsteady air waves to achieve gas boosting purposes, with high efficiency. The ordinary air wave supercharger described in the invention patents CN201210081062.0 and CN20121081102.1 utilizes the primary shock wave action of the high-pressure air flow to perform supercharging, which can achieve a higher supercharging ratio, but its expansion ratio is insufficient, resulting in latent heat of ...
