[0022] By adopting the above technical solution, the large impurity filter 5 filters the larger impurities carried by the gas and cleans them again through the bag filter 2. Before entering the filter barrel 7 below, the activated carbon adsorption plate 13 on the inner side of the filter barrel 7 removes the odor in the gas, and then the floating impurities are removed through the fine fiber layer 8, ensuring that the discharged gas meets higher standards.
