[0002] Yeast is a single-cell microorganism that has the ability to convert sugar into alcohol and carbon dioxide through anaerobic respiration and glycolysis. Under aerobic conditions, yeast undergoes normal respiration to produce carbon dioxide and water; under anaerobic conditions, yeast undergoes fermentation to produce alcohol and carbon dioxide. Bacteria produce tail gas during respiration. If the tail gas is directly discharged into the environment, it will cause environmental pollution and needs to be collected and treated.

At this time, the exhaust gas is adsorbed by the activated carbon adsorption plate, and then discharged to the outside through the cylinder cover after the adsorption is completed, so that the equipment has the advantages of high exhaust gas treatment efficiency and can effectively prevent exhaust gas from polluting the environment."

[0004] Among them, when replacing the activated carbon adsorption disk of the biological fermentation feed exhaust gas treatment device, the two pulling columns are first moved relatively to move the two second sliding blocks out from the inside of the annular groove, and then the fixing ring is moved upward to take the activated carbon adsorption disk out from the inside of the treatment cylinder.
