Rectification tower is a kind by the rectification equipment with hep people, that fractionating tower, whether is their action same? What principle to rely on to have the job respectively? The answer is in in content.
Rectification tower is the unit of contact of fluid of tower type steam that has rectification, include to have board type tower and filling tower two kinds of main types. Be entered from tower bottom when steam and with drop after fluid has refluent contact, drop in fluid easy volatilize group branch begins to be transferred to the middle of steam ceaselessly, and in steam difficult volatilize constituent falls downward ceaselessly the move in fluid. When steam approachs cat head more, its are easy volatilize constituent concentration is higher; And drop fluid nears tower end more, its are difficult volatilize constituent exceeds rich volume, achieve the goal with detached constituent. Fractionating tower also is to undertake rectification works likewise, but it is with the mixture at rectification fractional distillation commonly organic in all boil content, in all boil content is met in its interior first be heated rises to fractional distillation paragraph, high-test continues to rise. Because cat head is in,be agreed by the after conducting heat temperature of content of low boiling point and content of low boiling point, so content of low boiling point is come out by fractional distillation, and content of higher boiling point reachs relevant boiling point because of doing not have and circumfluence plays half part to fractional column, after waiting for content of low boiling point to be given by complete heat up in a steamer, content of higher boiling point in succession by fractional distillation, the heat up in a steamer that is content of high boiling point next goes out, bottom is residual after.
