Problems solved by technology

But usually the wave rotor does not consider the efficiency of expansion and refrigeration, nor does it return and compress the expanded low-pressure gas, so it cannot produce medium-pressure refrigerant gas

Abstract

A radial flow type self-pressurization air wave refrigerating device and a refrigerating method thereof can pressurize refrigerated air by using effective energy of high-pressure air directly during air wave expansion refrigeration, obtain low-temperature middle-pressure refrigerating air through cooling capacity exchange and greatly improve usable quality. The radial flow type self-pressurization air wave refrigerating device and the refrigerating method develop compression capacity along with the air wave expansion refrigeration, and high-pressure air energy is converted into precious pressure energy. Energy is not consumed too much, heat exchange in an expansion and compression process can be reduced, and the refrigeration temperature is lower. The centrifugal pressure difference is also utilized tactfully, low-pressure air energy can flow back by itself, and an extra driving flow fan is not required. By means of the radial flow type self-pressurization air wave refrigerating device and the refrigerating method, the pressure energy of the high-pressure air can be fully utilized and converted, natural gas pressure energy of a high-pressure gas well is suitable for being used for refrigerating, heavy components are dehydrated and purified and condensed, and the radial flow type self-pressurization air wave refrigerating device and the refrigerating method are applicable to the technical fields of pressure energy utilization of industrial waste gas and low-temperature copious cooling 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...
