陶瓷拉西環(huán)

拉西環(huán)具有優(yōu)異的耐酸耐熱性能，能耐除氫氟酸以外的各種無(wú)機酸、有機酸及有機溶劑腐蝕，可在各種高溫場(chǎng)合使用，應用范圍十分廣泛

產(chǎn)品描述

產(chǎn)品概述：

拉西環(huán)是塔歷史上最早的、具有固定幾何形狀的環(huán)形填料，其特點(diǎn)是：填料環(huán)的外徑與高度相等，結構簡(jiǎn)單，價(jià)廉，但存在液體分布不均勻和嚴重的壁流溝流現象等據點(diǎn)。現在一般用耐腐蝕的陶瓷拉西環(huán)在制酸工業(yè)中使用。拉西環(huán)填料于1914年由拉西（F. Rashching）發(fā)明，為外徑與高度相等的圓環(huán)。拉西環(huán)填料的氣液分布較差，傳質(zhì)效率低，阻力大，通量小，目前工業(yè)上已較少應用。它的形狀簡(jiǎn)單，其高度與直徑尺寸相等。大尺寸的拉西環(huán)（100mm以上）一般采用整砌方式規則填充，76mm尺寸以下的拉西環(huán)一般采用亂堆方式裝填，

產(chǎn)品特點(diǎn)：

拉西環(huán)具有優(yōu)異的耐酸耐熱性能，能耐除氫氟酸以外的各種無(wú)機酸、有機酸及有機溶劑腐蝕，可在各種高溫場(chǎng)合使用，應用范圍十分廣泛，

適用范圍：

可用于化工、冶金、煤氣、環(huán)保等行業(yè)的干燥塔、吸收塔、冷卻塔、洗滌塔、再生塔等。
