The content of crude benzol reclaimed water can be substantially reduced, and then reduces debenzolizing tower heat consumption, improves product quality and production efficiency, reduces
Labor intensity.
In order to achieve the above object, the present invention is realized using following technical scheme：
One kind coalescence crude benzol oil water separator, including cylinder and the coalescer in cylinder, ring-shaped liquid distributor pipe
And drainage duct；Feed(raw material)inlet is set in the middle part of the cylinder, feed(raw material)inlet is in charge of with ring-shaped liquid and is connected；Coalescer is located at annular liquid
Below body distributor pipe；Cylinder top sets crude benzol outlet and separation water out, and separation water out connects the upper end of drainage duct, draining
Cylinder body bottom space is stretched into the lower end of conduit after passing through coalescer.
Sleeve is set in the coalescer, drainage duct is passed through from sleeve.
Top cover is set at the top of the cylinder, top cover is detachably connected with cylinder, and diffusion mouth is set on top cover；Cylinder body bottom, which is set, to be put
Eat dishes without rice or wine and base.
The coalescer is made of hydrophilic oleophobic material, is fixed on by fixing device in cylinder.
A kind of method of work for coalescing crude benzol oil water separator, comprises the following steps；
1) after the crude benzol through debenzolizing tower overhead extraction is condensed through crude benzol condensate cooler, coalescence crude benzol is entered by feed(raw material)inlet
In oil water separator, subsequently into ring-shaped liquid distributor pipe, sprayed downwards from each fluid jetting head, the uniform flow in cylinder
It is dynamic, inner barrel is entered with laminar condition；
2) coalescer is made up of hydrophilic oleophobic material, and the small water droplet in crude benzol is first on the coalescing medium surface of coalescer
Soak and adsorb, then other small water droplets and the droplet collision first adsorbed and aggregation, make the drop being adsorbed on coalescing medium not
Disconnected increase, when increasing to a certain extent, the drag force of fluid removes the drop of coalescence from coalescing medium surface；It is continuous to occur
Wetting absorption, collision, aggregation and removing, enable dispersed phase-water and continuous phase-crude benzol to rely on gravitational separation, and then reach two
The effect of phase separation；
3) water of coalescence enters cylinder body bottom space, and continues reliance on gravity and be layered, and the water of bottom is led by draining
Pipe is discharged by separation water out；The upper strata crude benzol clarified by gravity is exported by the crude benzol on cylinder top and discharged.
Compared with prior art, the beneficial effects of the invention are as follows：
The operation principle of the present invention is the small water droplet after debenzolizing tower in crude benzol is attracted to coalescer surface, forms flood
Depart from coalescer after drop, then separated by gravity with crude benzol；The present invention can substantially reduce the content of crude benzol reclaimed water, and then drop
Low debenzolizing tower heat consumption, improves product quality and production efficiency, and reduces labor intensity.
