wkFY型廢氣洗滌塔

I. principle and structure:

The equipment itself includes the body, the filling layer, the defogging layer, the circulating sprinkling pipe, and the circulating water tank.

Ii. Scope of application:

Electronic industry, semiconductor manufacturing, PCB manufacturing, LCD manufacturing, steel and metal industry, electroplating and metal surface treatment industry, pickling process, dye, pharmaceutical, chemical industry, deodorization, combustion exhaust gas SO×/NO× removers and other water-soluble air pollutants treatment.

Iii. Exhaust gas washing process:

       噴淋塔內(nèi)填料層作為氣液兩相間接觸構(gòu)件的傳質(zhì)設(shè)備。

       填料塔底部裝有填料支承板，填料以亂堆方式放置在支承板上。填料的上方安裝填料壓板，以防被上升氣流吹動(dòng)。噴淋塔噴淋液從塔頂經(jīng)液體分布器噴淋到填料上，并沿填料表面流下。氣體從塔底送入，經(jīng)氣體分布裝置分布后，與液體呈逆流連續(xù)通過填料層的空隙，在填料表面上，氣液兩相密切接觸進(jìn)行傳質(zhì)。當(dāng)液體沿填料層向下流動(dòng)時(shí)，有時(shí)會(huì)出現(xiàn)壁流現(xiàn)象，壁流效應(yīng)造成氣液兩相在填料層中分布不均，從而使傳質(zhì)效率下降。因此，噴淋塔內(nèi)的填料層分為兩段，中間設(shè)置再分布裝置，經(jīng)重新分布后噴淋到下層填料上
