Embodiment 1

[0026] A way to reduce brewery CO 2 The method of oxygen content in the process of gasification, firstly, the liquid carbon dioxide in the liquid storage tank 1 with a pressure of 1.5-1.8 MPa is first vaporized by the vaporization device 2 to become gaseous carbon dioxide, and then decompressed to 0.6-0.6 by the decompression device 3. 0.9 MPa enters the oxygen removal device 4, and passes through the adsorbent filled in the oxygen removal device (the adsorbent can be an alloy such as manganese), the flow rate of carbon dioxide in the adsorbent is 10-30 m / s, and the carbon dioxide contained in the carbon dioxide gas is absorbed by the adsorbent Oxygen adsorption realizes deoxygenation, and the deoxygenated carbon dioxide gas passes through the filter device 5 to remove dust and odor, and finally the deoxygenated carbon dioxide gas can enter the high-concentration diluter and / or wine filter pipeline for use.

Embodiment 2

[0028] A way to reduce brewery CO 2 A complete set of oxygen content in the gasification process, which includes CO 2 Carburetor 2, decompression device 3 (CO 2 pressure reducing valve), oxygen removal device 4 and filter device 5, such as figure 1 As shown, CO 2 The input of vaporizer 2 is connected to the CO 2 Connected to the output of liquid storage tank 1, CO 2 The output end of the vaporizer 2 is connected to the input end of the decompression device 3, the output end of the decompression device 3 is connected to the input end of the oxygen removal device 4, the output end of the oxygen removal device 4 is connected to the input end of the filter device 5, and the filter device The output end of 5 is connected with the input end of high-concentration diluter 6, and adsorbent is filled in deaeration device 4, such as figure 1 As shown, the adsorbent in the oxygen removal device 4 can be an alloy such as manganese, and the flow rate of carbon dioxide in the adsorbent ...

Abstract

The invention relates to a method and a complete set of equipment for reducing oxygen content in gasification process of CO2 gas of a brewery. The equipment is characterized in that an adsorbent is filled in an oxygen removal device, the adsorbent can adsorb trace oxygen from the carbon dioxide gas during the using process under a normal temperature and pressure state, and the CO2 gas is not affected by the process so as to ensure that the oxygen content in the CO2 gas at the end use end can reach a very low standard. According to the method and the equipment, disclosed by the invention, the different physical and chemical properties of the carbon dioxide and the oxygen in the carbon dioxide are fully utilized, the oxygen removal device can smoothly separate oxygen from the carbon dioxide, the energy consumption is very low, and the emission of the carbon dioxide into an atmosphere can be simultaneously reduced, which is favorable for environmental protection.

Description

technical field [0001] The invention relates to a liquid carbon dioxide application technology, in particular to a method and device for reducing the oxygen content in carbon dioxide gas by using the principle of adsorption due to the high oxygen content after the liquid carbon dioxide gasification process, specifically a method and device for reducing the oxygen content of beer Factory CO 2 A method and a complete set of equipment for oxygen content in a gas gasification process. Background technique [0002] As we all know, during the beer preparation process, carbon dioxide needs to be added to the beer liquid to ensure its taste. The oxygen content in the gas when using carbon dioxide in a brewery determines the freshness period and taste of beer. The higher the oxygen content, the fresher period The shorter it is, the worse the taste. With the improvement of national living standards, breweries have higher and higher requirements for the oxygen content in the process ...
