Embodiment

[0036] The gas demister structure of the present embodiment is as figure 1 and figure 2 as shown,

[0037] The mesh number of the screen 3 is 20 mesh, the material is high-strength polytetrafluoroethylene, and the number of screen modules is 3;

[0038]The surface of the screen is sprayed with a catalyst with a thickness of 0.5 μm to 20 μm;

[0039] The active ingredient of the catalyst is metal palladium particles;

[0040] The particle size of the catalyst component is 50-100nm;

[0041] The weight percentage of the active ingredients of the catalyst in the catalyst layer is 0.01wt% to 0.08wt%;

[0042] The carrier of the active component of the catalyst is α-Al 2 o 3 .

[0043] The support block 1 is welded on the middle inner wall 5 of the upper space of the packing bubble, and the three wire mesh modules are respectively fixed on the support block 1 by fasteners 2, which are Φ12 stainless steel stud bolts.

[0044] The packed bubbling bed gas demister provided by...

Abstract

The invention discloses a gas foam remover for an acetylene hydrogenation type ethylene preparation packing bubbling bed. The gas foam remover comprises a 15-25-mesh screen mesh and a screen mesh mounting part, the screen mesh mounting part is fixed to the inner wall of the upper middle portion of the packing bubbling bed, and the screen mesh is coated with a catalyst and fixed to the screen mesh mounting part. Since the screen mesh coated with the catalyst is arranged on the gas foam remover, escape of solvent volatile components is prevented while trace acetylene in reaction products can be converted completely, and structural simplicity and easiness in mounting are realized.

Description

technical field [0001] The invention belongs to the field of chemical equipment and equipment manufacturing, in particular to a gas demister for producing ethylene packed bubbling bed by hydrogenation of acetylene. Background technique [0002] With the depletion of petroleum resources, the development of coal chemical industry as a raw material chemical process has become an important process to replace the petrochemical route, which has attracted widespread attention and achieved rapid development. [0003] In coal chemical technology, the production of acetylene by using coal as raw material through calcium carbide process has been widely used. Using acetylene as raw material under the action of selective hydrogenation catalyst to produce ethylene products through hydrogenation can further expand the route of coal chemical industry. Moreover, in recent years, the supply of polyvinyl chloride (PVC), the main downstream product of acetylene, has exceeded demand, and the PVC...
