High purity reagent production line structured packing device. The device is installed inside the rectifying tower as the internal accessories of the distillation column, and is cylindrical. It is composed of many pieces of stainless steel 316L mesh. It is made up of three wire mesh hoops. Each piece of wire mesh is pressed into corrugated shape. The angle of the corrugation is circular. The inclination angle is 45 degrees. The adjacent two corrugated wires have opposite directions. When the packing device is installed in the distillation tower, the filler on the upper and lower plates is staggered 90 degrees. In the process of using, enter the filler material by steam from the tower bottom rising and uniform material, steam in the rising process of continuous evaporation condensation heat exchange, condensate through the arc angle of structured packing dispersed to flow under the tower kettle, and falling film formed in the filler layer, the condensed liquid drops and materials steam rising full contact, vapor-liquid exchange thoroughly, to ensure the separation of impurities completely, improve the quality and stability of products.

高纯试剂生产线规整填料装置
本技术属于高纯试剂产品生产线精馏工艺
,涉及一种高纯试剂生产线规整填料装置。
技术介绍
高纯试剂产品生产使用的原料是工业级原料,工业级原料经过前处理后,再通过精馏塔精馏将处理过的原料中的杂质彻底分离去除后,得到的就是高纯试剂产品。在生产过程中,常用的精馏塔可以分为两大类,为板式塔和填料塔。板式塔虽然应用比较广泛,但其塔径大,能耗高,塔效率相对较低,散堆填料塔主要是压降较大,塔体不宜过高,这些塔对于痕量杂质的分离不够彻底,稳定性也比较差。使生产出来的高纯试剂产品质量低且非常不稳定,产品时好时坏,无法满足我国高领域方面的需要。这就是我国的高纯试剂产品的生产瓶颈,从而导致我国的高纯试剂产品在这一领域的缺失,被国外产品所垄断。
技术实现思路
