Including defoamer, gas bladder, scrubber tower, circulating water pump. Carbon dioxide gas from the fermentation tank area by the sugar remover in addition to sugar first into the recovery room set up by the carbon dioxide defoamer, defoamer is further removed through the water shower sugar and foam device, gas storage bag is temporarily stored after the initial purification of the gas, to maintain the fermentation gas source pressure balance and compressor suction pressure stability, the compressor plays a buffer role in avoiding no incoming gas damage to the compressor, the storage bag is connected through the contact switch can send the storage signal to the system control center, the control center automatically control the whole carbon dioxide recovery system start and stop. The gas storage bag can send the gas storage signal to the system control center through the contact switch, and the control center will automatically control the start and stop of the whole carbon dioxide recovery system. The scrubber tower is equipped with stainless steel packing, thus increasing the contact area between gas and water. The water in the scrubber tower passes through the spraying system on the top of the packing system to form a small waterfall, and the carbon dioxide gas passes through the countercurrent, and the water forms a liquid film on the surface of the packing to remove the water-soluble impurities in the fermentation gas, such as alcohol and so on. The circulating pump is used to circulate the washing water in the washing tower to achieve the goal of fully utilizing and saving water, the washing water is in direct contact with carbon dioxide, so it is necessary to use tap water after the washing pre-treatment unit.
