This water is then sprayed through the spray pipe 16 and spray head 17 into the upper part of the first biological packing material 11. As the dust-laden gas enters the first grid support 14 and the first biological packing material 11, the foam at the upper part of the first biological packing material 11 filters the dust from the gas, thus facilitating the treatment of the dust-laden gas. The water droplets formed by foam condensation fall into the interior of the washing tower body 1. Then, the dust-laden water at the bottom of the washing tower body 1 flows through the circulating return water pipe 21 into the interior of the wastewater filter box 7. The filter cartridge 25 then filters the impurities inside the water body. The filtered liquid then goes through the circulating water pipe 20 and the circulating water pump 8 for the next cycle of circulation. When replacing and cleaning the filter cartridge 25, the staff removes the locking bolt 19 and the sealing mounting plate 18, and the filter cartridge 25 can be removed from the outer end of the mounting ring 23 for disassembly and cleaning.
