金屬共軛環(huán)

金屬共軛環(huán)揉合了環(huán)形和鞍形填料的優(yōu)點(diǎn)，采用共軛曲線(xiàn)肋片結構，兩端外卷邊及合適的長(cháng)徑比、填料間或填料與塔壁間均為點(diǎn)接觸，不會(huì )產(chǎn)生疊套、孔隙均勻、阻力小，亂堆時(shí)取定向排列，幫有規整填料的特點(diǎn)，有較好的流體力學(xué)和傳質(zhì)性能。

金屬共軛環(huán)

產(chǎn)品介紹

金屬共軛環(huán)揉合了環(huán)形和鞍形填料的優(yōu)點(diǎn)，采用共軛曲線(xiàn)肋片結構，兩端外卷邊及合適的長(cháng)徑比、填料間或填料與塔壁間均為點(diǎn)接觸，不會(huì )產(chǎn)生疊套、孔隙均勻、阻力小，亂堆時(shí)取定向排列，幫有規整填料的特點(diǎn)，有較好的流體力學(xué)和傳質(zhì)性能。

產(chǎn)品特點(diǎn)

在塔內堆放時(shí)發(fā)生沿軸向重疊套合現象；其內肋結構呈共軛形狀，在塔內時(shí)很均勻，故使液體在填料表面上的分布也均勻；相鄰填料的內肋與表面接觸的點(diǎn)數多，可以加劇液體的聚散和表面更新；這些特點(diǎn)使共軛環(huán)對流體的阻力小，而提供氣，液相接觸的表面大，從而已改善了填料的流體力學(xué)和傳質(zhì)性能。所以共軛環(huán)填料是一種通量大、壓降低、傳質(zhì)效率高、操作彈性大的填料。
