Description
Technical field
The utility model relates to chemical industry equipment field, exactly relates to a kind of Despumation device of acetate production use.
Background technology
Demister is usually used in the drop that rectifying separation of produced device gas is carried secretly, to ensure mass-transfer efficiency, and the operation of compressor after reducing valuable loss of material and improving tower.In acetate is produced, product is by evaporation, and product enters esterification column with gas phase form.Between reactor and esterification column, demister is set, also can reduces liquid foam entrainment, comprise carrying secretly of catalyst etc., reduce corrosion, be conducive to produce.Traditional demister air inlet is single channel, and because effective liquid collection passage is not set, and single channel gas phase is easily to the liquid foam impact having separated, and affects the separation of gas-liquid.Meanwhile, in present the used demister of acetate, often because air-flow is large, the separation of liquid foam is also difficult to not thorough, and catalyst sulfuric acid also is easily carried secretly out, thereby apparatus is caused to corrosion, has affected to produce normally to carry out.
Summary of the invention
For overcoming the deficiencies in the prior art, the Despumation device of a kind of acetate production use that the utility model provides can improve the separative efficiency of demister, can effectively collect, effectively stop carrying secretly of sulfuric acid to isolated drop, be conducive to acetate and normally produce, improve acetate productivity effect.
The technical scheme that the utility model is taked is:
A kind of Despumation device of acetate production use, comprise charging aperture, discharging opening, packing support, enamel filler, filler pressing, upper stack shell, lower stack shell and sewage draining exit, lower stack shell bottom is provided with sewage draining exit, side is provided with charging aperture, the head of upper stack shell is provided with discharging opening, between upper stack shell and lower stack shell, connect through flange, packing support is arranged in lower stack shell, enamel filler is between packing support and filler pressing, between described enamel filler and lower stack shell inwall, be provided with feeder, between hold-down grid and discharging opening, be provided with spiral board assembly.
Further, described feeder is the cannelure being welded on lower stack shell inwall.
Further, described feeder is provided with feeder leakage fluid dram.
Further, described spiral board assembly comprises rotating shaft and tilts to be welded in the many groups rotation blade on rotating shaft.
Again further, described charging aperture is two groups of symmetrical and just right charging apertures, and the centre position of two charging apertures is provided with baffle plate.
Take after above technical scheme, the beneficial effects of the utility model are: on the basis of existing Despumation device, be optimized, between packing layer and cylindrical shell, increase a circular feeder, when reactant mixture material is by filler and spiral board after separating, isolated drop can effectively be collected by feeder, avoid being carried secretly by air-flow, improve the efficiency of collecting; Change single charging aperture of existing demister into symmetry and just right two charging apertures, add a baffle plate in two charging aperture centre positions, mixture stream can make air-flow more stable by two air inlet access arrangements, flow to more concentrated, distribute more evenly, more stable, make the better effects if separating, improved separative efficiency.
Novel demister can effectively reduce carrying secretly of liquid foam, improves the collection utilization to isolated liquid, increases the separative efficiency of demister entirety.Control is carried secretly catalyst sulfuric acid, reduces the corrosion to apparatus, is conducive to the normal production of acetate.
