Double-layer nozzle and double-row pipe gas wave refrigerator with built-in drive hydraulic balance

Abstract

The invention belongs to the technical field of pressure gas expansion refrigeration, and relates to a double-layer nozzle and double-row pipe gas wave refrigerator with built-in drive hydraulic balance. According to the double-layer nozzle and double-row pipe gas wave refrigerator, double layers of nozzles mounted on a main shaft of the gas wave refrigerator are used for jetting gas into corresponding double rows of vibration receiving pipes so as the achieve the aims of increasing the number of the receiving pipes by one time and increasing the handling capacity. A hydraulic balance device is built for offsetting, overcoming and balancing the disadvantage that the axial force is increased due to axial gas input, and the problem causing shortening of the service life of the refrigerator can be effectively solved. A transmission device is arranged in the middle segment of the refrigerator in an embedded manner and is driven by a motor, and the contradiction that the two ends of the refrigerator are occupied is solved well. In order to prevent gas mixing and outward leaking before and after refrigeration so as to improve the refrigeration efficiency, the refrigerator mainly selectsmultiple single-end-face mechanical seals besides a labyrinth seal and a spiral seal, the mechanical seals can adapt to the production work conditions of the gas wave refrigerator well, and the long service life of equipment and stable and safe operation can be guaranteed.

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 e...
