The invention discloses complete equipment for CO2 recycling with a CO2 vaporization and cool recycling device, comprising a CO2 compressor (1), a CO2 drying device (2), a re-boiler (17), a refrigeration compressor (16), a liquefying heat exchanger (4), a liquid storage tank (5) and a carburetor (9). The complete equipment is characterized in that an energy storage tank (10) is installed between the liquid storage tank (5) and the carburetor (9); the pressure of the liquid CO2 in the liquid storage tank (5) is higher than that of the liquid CO2 in the energy storage tank (10); the energy storage tank (10) is connected with the heat exchanger (8); the refrigerating medium in the energy storage tank (10) is circulated between the energy storage tank (10) and the heat exchanger (8) by a circulating pump (11) and a connecting pipeline; the CO2 gas inlet of the heat exchanger (8) is directly communicated with the gas outlet of the re-boiler (17); the gas outlet of the heat exchanger (8) isdirectly communicated with the liquid CO2 inlet of the liquefying heat exchanger (4); and the liquid CO2 directly flows from the liquefying heat exchanger (4) to the re-boiler (17) and is pumped intothe liquid storage tank (5) after impurities are removed. The invention realizes the energy recycle by additionally arranging the energy storage tank and the heat exchanger and remarkably saves the energy.
Description
technical field [0001] The invention relates to a carbon dioxide recycling device, in particular to a carbon dioxide recycling device that utilizes a large amount of cold energy generated during the gasification process of liquefied carbon dioxide as an energy source for liquefying the recovered gaseous carbon dioxide so as to stop the refrigeration compressor to save energy. Specifically, it is a very significant energy-saving effect with CO 2 CO vaporization cold recovery unit 2 Recycling sets. Background technique [0002] As we all know, in the beer preparation process, it is necessary to add carbon dioxide to the beer liquid to ensure its taste. Carbon dioxide can be directly purchased from the market for food-grade liquid carbon dioxide and added to the beer after heating. This is very expensive. On the one hand, a large amount of carbon dioxide will be produced in the beer brewing process, and direct discharge will not only cause waste, but also pollute the environm...
