Technical Field

[0001] The utility model relates to the technical field of cold energy recovery, in particular to a cold energy recovery device inside and outside a carbon dioxide system. Background Art

[0002] Carbon dioxide is an important compound and one of the important substances in nature. Carbon dioxide is a colorless and odorless gas at room temperature and pressure. At a standard atmospheric pressure, its sublimation temperature is -78.5℃, its critical temperature is 31.1℃, its supercritical pressure is 7.4MPa, and its relative molecular mass is 44.01. When pressurized below the critical temperature, carbon dioxide gas can be liquefied into colorless liquid carbon dioxide. Carbon dioxide is a valuable resource that can be used and has been listed as one of the most friendly gases to humans by the World Organization. Industrial-grade liquid carbon dioxide is mainly used in carbon dioxide gas shielded welding, carbon dioxide fire extinguishing equipment, petrochemical industry, biochemical industry, oil extraction, etc. Food-grade liquid carbon dioxide is mainly used in beverage and beer additives, tobacco puffing, food preservation, carbon dioxide supercritical extraction, etc.
