Abstract

The invention discloses a gas cooling system and a gas cooling method, including a compressor, a first heat exchange device, a regenerator, a first cooling tower, and a second heat exchange device, and the first heat exchange device includes at least a first flow channel and the second flow passage, the compressor communicates with the first flow passage, the first flow passage communicates with the first cooling tower; the second flow passage communicates with the regenerator; the second exchange The thermal device at least includes a third channel, a first cavity, a fourth channel and a second cavity, the fluid in the third channel exchanges heat with the fluid in the first cavity, the fluid in the fourth channel exchanges heat with the fluid in the The heat exchange of the fluid in the second cavity, the first cavity can communicate with the second cavity, the regenerator can communicate with the first cavity, and the first cavity can communicate with the second flow channel; The fourth flow channel communicates with the first cooling tower. The invention provides a gas cooling system and a gas cooling method, which can provide low-temperature air required for air separation.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a precooling system in a gas cooling system. Background technique [0002] Air separation (referred to as air separation) technology is mainly used to produce liquid oxygen, liquid nitrogen, liquid argon, helium and other industrially required gases through low-temperature liquefaction of air in the atmosphere. The gas produced is mainly used in steelmaking, coal chemical industry, medical treatment and other industrial and civil occasions. A typical air separation system usually includes air purification, molecular sieve, compressor, pre-cooling system, rectification system and other related supporting systems. [0003] In a typical air separation plant pre-cooling treatment system, the temperature of the high-temperature and high-pressure air from the final compressor reaches about 105°C, and in the first cooling tower, the heat exchange with the normal temperature water (32°C) from ...
