Abstract

Disclosed are an axial-flow type self-pressurization gas wave refrigerating device and a refrigerating method thereof. By means of the refrigerating device and the refrigerating method thereof, gas wave expansion refrigeration can be performed, simultaneously, energy of high pressure gas waves can be directly utilized to boost pressure of refrigerated gases, low-temperature medium-pressure refrigerated gases can be obtained through cooling capacity exchange, and usable qualities of the refrigerated gases are greatly improved. According to the refrigerating device and the refrigerating method thereof, compression capacity accompanied by gas wave expansion refrigeration is developed to convert high pressure gas energy into precious pressure energy, consumed energy is not increased, heat exchange during expansion and compression can be reduced, and the refrigeration temperature is low. Besides, pressure energy of high pressure gases is fully used and converted, and the refrigerating device and the refrigerating method thereof are suitable for technical fields of refrigeration, dehydration and purification, condensation of heavy components in gases by natural gas pressure energy of a high pressure gas well, pressure energy utilization and low-temperature copious cooling of industrial waste gases and the like.

Description

technical field [0001] The invention discloses an axial-flow self-pressurized gas wave refrigeration device and a refrigeration method thereof, belonging to the technical field of gas expansion refrigeration. Background technique [0002] Gas expansion refrigeration is a commonly used refrigeration process technology. Improving the efficiency of expansion refrigeration has important economic and social benefits in today's energy shortage. Commonly used equipment for expansion refrigeration includes turbo expanders, heat separators, gas wave refrigerators, and throttle valves. Among them, the gas wave refrigeration machine has a simple structure, low speed, and high refrigeration efficiency. The "gas wave refrigerator", "multi-stage gas wave refrigerator" and "outer circulation dissipative gas wave refrigerator" developed and invented by Dalian University of Technology have obtained national patents. [0003] However, compared with the turbo expander, the gas wave refriger...
