This creation provides a kind of improvement construction for filtering dust,Main system includes: a fan as exhausting user； One water Lian piece is installed on the wall of one transmission of what,As impurity screening person； One sink installs what water Lian piece bottom,It is acted on as the aqueous that water Lian piece flows out down is collected； One water pipe,If the what water Lian on piece, which is used as, sprays aqueous user,Nozzle is equipped at the ora terminalis of what water pipe； By said combination,When the dust impurities in animal house are extracted out by fan,Water pipe is equipped with by what water Lian on piece,And nozzle is installed on water pipe,The dust impurities pass through water Lian piece,The aqueous of nozzle ejection will be sprayed for the dust impurities,That is, the dust impurities will be stopped by the aqueous of water Lian piece and nozzle ejection and adhere to what water Lian on piece,Using the aqueous of nozzle ejection by the dust impurities toward the flows of water Lian piece,Sink is installed with by what water Lian piece bottom,Therefore the dust impurities will flow in sink,Making discharge is more clean gas,And the effect of reaching a filtering dust.本創作提供一種過濾粉塵之改良構造，主要係包括：一風扇作為抽風用者；一水濂片裝設於一透空之牆上，作為過濾雜質者；一水槽裝設於水濂片底部，作為收集水濂片往下流出之水液作用；一水管，設於該水濂片上作為噴出水液用者，於水管之端緣處設有噴嘴；藉上述組合，當畜舍內之粉塵雜質被風扇抽出時，由於水濂片上設有水管，而水管上固設有噴嘴，該粉塵雜質經過水濂片，噴嘴噴出之水液將針對該粉塵雜質噴灑，亦即該粉塵雜質將被水濂片及噴嘴噴出之水液所阻擋而附著於水濂片上，利用噴嘴噴出之水液將該粉塵雜質往水濂片之底部流動，由於水濂片底部裝設有水槽，因此該粉塵雜質將流向水槽內，使排出為較乾淨之氣體，而達到一過濾粉塵之功效。
