Description

Technical Field

[0001] The utility model relates to the technical field of liquid oxygen separation, and specifically relates to a liquid oxygen separation device. Background Technique

[0002] Liquid oxygen has a high energy density and a relatively high combustion efficiency, and is an important fuel in aeroengines. Through cryogenic air separation technology, oxygen in the air can be separated and liquefied into liquid oxygen to provide a stable fuel supply for aeroengines. The use of liquid oxygen can improve the thrust and combustion efficiency of the engine, thereby improving the performance and range of the aircraft. For this reason, a liquid oxygen separation device is proposed.

[0003] The existing Chinese utility model patent with the reference publication number of CN217876770U discloses a liquid oxygen evaporation and condensation heat exchange device for air separation, belonging to the technical field of condensation heat exchange. In this technical solution, it includes a vertical condenser. Inside the vertical condenser, there is a rotatable vertical heat exchange component. At the top of one end of the vertical condenser, there is a rotating mechanism for rotating the vertical heat exchange component; inside the vertical condenser, there is a horizontal scraper for cleaning scale, and at the other end of the vertical condenser, there is a lifting mechanism for lifting the horizontal scraper. The vertical heat exchange component includes a collection box, and a collection box is fixed at the bottom of the collection box, and a plurality of dispersion tubes are arranged at the bottom of the collection box. Through the rotating mechanism of the utility model, the dispersion tubes can be rotated, so that the dispersion tubes can be in full contact with the substances inside the vertical condenser, improving the heat exchange efficiency. Through the setting of the lifting mechanism and the horizontal scraper, it is prevented that the liquid film adheres to the outside of the dispersion tubes, ensuring the long-term heat exchange efficiency of the dispersion tubes.

[0004] Based on the retrieval of the above patent and the discovery of the equipment in the existing technology, it is found that due to technical reasons, the purification effect of liquid oxygen is not ideal after separation, and when separating liquid oxygen, heating is required, and the heating time of the compressor is limited, resulting in insufficient heating of liquid oxygen. The existence of these problems affects the use of the device. Content of the Utility Model
