Abstract

The invention discloses a wave rotor and a rotary thermal separator. The wave rotor comprises a rotor inner cylinder and a rotor outer cylinder, the rotor inner cylinder and the rotor outer cylinder are both cylinders with two open ends, the rotor inner cylinder and the rotor outer cylinder are coaxially and fixedly arranged, and at least two layers of annular cavities are formed between the rotor inner cylinder and the rotor outer cylinder in the radial direction of the rotor inner cylinder. A plurality of oscillation air passages which are arranged along the axial direction of the annular cavity are arranged in each layer of annular cavity, and the plurality of oscillation air passages in the same layer of annular cavity are distributed along the circumferential direction of the layer of annular cavity. The rotary thermal separator comprises the wave rotor. According to the multi-stage thermal separator, the problem that an existing multi-stage thermal separator adopting a single-layer channel wave rotor is low in system efficiency can be effectively solved.

Description

technical field [0001] The invention belongs to the field of gas jet technology, and more specifically relates to a wave rotor and a rotary heat separator. Background technique [0002] Rotary heat separator is a kind of refrigeration equipment close to isentropic decompression, which is mainly composed of nozzle, wave rotor and rotary distributor. The high-energy gas is sprayed into the oscillation tube of the wave rotor through the nozzle, and the existing gas in the oscillation tube is compressed and heated up, and the temperature rise can be as high as about 500°C. The heat generated by compression is transferred from the outer surface of the oscillating tube by natural convection or forced convection. Since the machine is equipped with a rotary distributor, the injection of gas is intermittent. When the gas in the oscillating tube is compressed and heated up, the air intake stops, the gas in the oscillating tube changes its flow direction, undergoes adiabatic expansio...
