A double-layer nozzle double-row tube gas wave refrigerator with built-in drive hydraulic balance

Abstract

A gas wave refrigerator with double-layer nozzles and double-row tubes with built-in driving hydraulic balance belongs to the technical field of pressurized gas expansion refrigeration. In the present invention, the double-layer nozzles installed on the main shaft of the air wave machine shoot air into the corresponding double-row oscillating receiving tubes, so as to achieve the purpose of doubling the number of receiving tubes and increasing the processing capacity. By establishing a hydraulic balance device to counteract, overcome and balance the unfavorable increase of the axial force caused by the axial air intake, the problem of shortening the life of the machine can be effectively solved; the transmission device is embedded in the middle of the machine and It is driven by a motor, which solves the contradiction of being occupied at both ends of the machine; in order to prevent gas mixing and leakage before and after refrigeration, and to improve refrigeration efficiency, this machine not only uses labyrinth seals and spiral seals, but also uses multiple A single-end mechanical seal, the mechanical seal can better adapt to the production conditions of the gas wave refrigerator, and can ensure the long life of the equipment and stable and safe operation.

Description

technical field [0001] The invention relates to a double-layer nozzle double-row tube gas wave refrigerator with built-in driving hydraulic balance, belonging to the technical field of pressure gas expansion refrigeration. Background technique [0002] Since the 1980s, Dalian University of Technology has developed gas wave refrigerators (patent number 89213744.4), multi-stage gas wave refrigerators (96115022. Top-mounted built-in gas wave refrigerator (ZL201410061539.8), a contact sealed inverted gas wave refrigerator (ZL201410119687.0), etc., these gas wave refrigerators have in common that they are driven by motors Or use the pressure difference between the inlet and outlet of the device to make the main shaft and the gas distributor spin, and at a certain rotation speed, the pressure medium gas will be jetted to the oscillating receiving tubes that are closed at each end in the circumferential direction, and the retained gas in the tube will not be affected. Constant exp...
