Multipurpose dehydrogenation reaction device

多用途脱氢反应装置

Abstract

The invention discloses a multipurpose dehydrogenation reaction device which comprises a top cover, wherein a reactant inlet is formed in the middle of the top cover, an upper plug and a lower plug at the bottom are arranged on the two sides under the top cover, and the upper plug and the lower plug are fixedly connected through a barrel section; through holes are formed in the upper end and the lower end of the barrel section, a wire mesh demister is arranged between the through holes formed in the upper ends, and a steam input pipe is arranged above the wire mesh demister; the through holes are communicated with a gas riser which is arranged on the wire mesh demister; a catalyst bed is arranged between the lower end of the barrel section. After gas to be dehydrogenated enters a reactor from the reactant inlet, the gas is fully mixed with steam inputted by the steam input pipe, so that partial pressure of reactant is reduced; when a mixture of the reactant and the steam downwards enters the wire mesh demister, gas and liquid are separated by the wire mesh demister, the liquid enters the barrel section, the gas enters a reaction area where a catalyst is supported by a small ceramic sphere, and a product generated by dehydrogenation reaction flows out of an outlet. The multipurpose dehydrogenation reaction device disclosed by the invention has the advantages of low construction cost and simple structure.
多用途脱氢反应装置,包括顶盖,顶盖中间设置有反应物入口,顶盖下方两侧分别设置有上封头与底部的下封头,上封头与下封头通过筒节固连;筒节的上下两端分别设置有通孔,上端的通孔之间设置有丝网除沫器,在丝网除沫器上方设置有蒸汽输入管;通孔与设置在丝网除沫器上的升气管相连通;筒节下端之间设置有触媒床;待脱氢的气体从反应物入口进入反应器后,与蒸汽输入管输入的水蒸气充分混合,降低了反应物的分压,当反应物与水蒸气的混合物向下进入丝网除沫器后,丝网除沫器将气液分离,液体进入筒节,气体进入瓷小球支撑着催化剂的反应区,脱氢反应后的生成物从出口流出;本发明具有造价低廉,结构简单的特点。
