For non-corrosive industrial waste gas, ordinary filter materials can be used, and for corrosive industrial waste gas, corrosion-resistant filter materials can be used.

使用时，先打开水泵 9,位于壳体 1内腔的叶轮 2下方的两喷液头 10向上 喷水； 当工业废气进入壳体前腔时， 由于气流风压及喷液头喷水的作用力，使叶 轮 2旋转，喷出的水在旋转叶轮 2的作用下形成水雾，废气中的污染颗粒与水雾 混合、碰撞并在离心力作用下被甩到壳体 1内腔的筒状过滤器 6上。当旋转气流 进入螺旋导流器 5时与螺旋导流器 5发生碰撞，污染颗粒也被甩向壳体内腔的筒 状过滤器 6上，污染颗粒和气流中的异味被筒状过滤器 6吸附，水流渗过筒状过 滤器滤芯的空隙流向水箱 8， 而净化过的气流继续吹向壳体排气口排出。 In use, the water pump 9 is first opened, and the two liquid discharge heads 10 located below the impeller 2 in the inner cavity of the casing 1 are upwardly When the industrial waste gas enters the front cavity of the casing, the impeller 2 rotates due to the air flow pressure and the action of the water sprayed by the liquid spray head, and the sprayed water forms a water mist under the action of the rotary impeller 2, and the waste gas The contaminated particles are mixed with the water mist, collide, and are sucked onto the cylindrical filter 6 of the inner cavity of the casing 1 by centrifugal force. When the swirling airflow enters the spiral deflector 5, it collides with the spiral deflector 5, and the contaminated particles are also impinged on the cylindrical filter 6 of the inner cavity of the casing, and the odor of the contaminated particles and the airflow is adsorbed by the cylindrical filter 6. The water flows through the gap of the cylindrical filter element to the water tank 8, and the purified air stream continues to be blown toward the casing exhaust port.
