[0002] Yali Pear Vinegar is a new type of fruit vinegar made from Yangxin Yali Pear using modern biotechnology. The production process of Yali Pear Vinegar mainly involves two microbial metabolism stages: alcohol fermentation and acetic acid fermentation. These two links may produce a small amount of waste gas. The waste gas generated during the production of Yali Pear Vinegar mainly includes carbon dioxide in the alcohol fermentation stage and volatile organic compounds and trace organic acid droplets in the acetic acid fermentation stage. Although these waste gases are not highly toxic, they need to be reasonably treated to control odor, concentration and environmental compliance.

[0003] The existing methods for treating waste gas generated by duck pear vinegar production are mostly through condensation and filtration, but the waste gas of duck pear vinegar is usually acidic, and the condensed water generated during condensation is usually acidic. The condensed water remains in the condenser after condensation. If the condensed water is not treated in time, it will cause the condenser to corrode and form scale, etc., causing the condenser to be blocked, affecting the condensation effect and affecting the service life of the condenser.

A fan can be installed separately on the outside to blow air to the first heat sink 18 and the second heat sink 26 to dissipate heat, so as to achieve a better heat dissipation effect and ensure the cooling effect of the first refrigeration fin 17 and the second refrigeration fin 25. The colder water in the water tank 5 is sprayed, which can achieve a certain condensation effect while spraying, and the colder water can better cool the connecting pipe 10 to ensure the condensation effect of the connecting pipe 10.

[0046] When it is necessary to discharge the condensed water, the first electric valve 15 is started so that the condensed water flows between the first electric valve 15 and the second electric valve 16. Then the first electric valve 15 is closed and the second electric valve 16 is opened to discharge the condensed water. In this way, the condensed water can be discharged and purified at the same time, thereby improving the overall work efficiency.
