This creation provides a dust filter structure.Including: a fan,As a draught user;A wind chamber,It is a hollow structure device.The connection is fixed at the rear end of the fan.As a guide wind direction,The air guide room is provided with a water link.As filter impurities,A curved sheet body is arranged at the top of the air guide chamber;A spray pipe,On the air guide room,A person who sprays water into a wind guide room.The front end of the spray pipe is provided with a spray head;A water pump motor,As the liquid in the air guide room is pumped out for recycling;When the exhaust pollutants in the livestock house are exhausted by the fan,At this time, the exhaust gas will flow to this end.Since the spray pipe is set in the middle of the air guide chamber,Therefore, the ejected liquid can spray the waste gas and make the dust and dirt fall down.Make the discharge cleaner.It can filter dust and dirt.When dust and dirt fall down,Through the filtering effect of water Lian tablet, impurities are retained on it.The downward flowing liquid is pumped by the pump motor.The water source can be recycled.本創作提供一種粉塵過濾構造,包括:一風扇,作為抽風用者;一導風室,為中空構造裝置,連接固設於風扇後端,作為引導風向排出於外,於導風室內設有水濂片,作為過濾雜質,導風室內部頂端設彎曲片體;一噴水管,設於導風室上,作為向導風室內噴入水液者,噴水管前端設有噴水頭;一抽水馬達,作為將導風室內液體抽出而作循環使用;當畜舍內廢氣污染物經風扇抽出而排出於外,此時該廢氣將往該端處流動,由於導風室中間設噴水管,因此噴出液體可對廢氣噴灑而使粉塵污物往下掉落,使排出較乾淨氣體,達到過濾粉塵污物功效,當粉塵污物往下掉落,經過水濂片過濾功效使雜質滯留於上,往下流動之液體經抽水馬達之抽取,使水源達到循環利用效果。
