The stabilizing plate 213 is combined with the tank cover 21 and the waterproof pump 71 by conventional methods. When the waterproof pump 71 operates, the sedimentation water accumulated in the cavity B is suctioned, and the connecting pipe 73 transports the sedimentation water to the shunt pipe 74 and then flows into the interior of the shunt ring 75. The water in the shunt ring 75 sprays out from the spray nozzles 751, and the mist beads adsorb the large particulate impurities of the soot to form mist bead clusters and settle. There is a dust reduction design for the large particulate dust impurities mixed in the smoke-containing air during ventilation and air change. A blocking plate 22 is provided inside the water storage tank 2, and the blocking plate 22 blocks the mist bead clusters carried by the air flow.
