Description

Destilling tower washing section withdrawing oil distribution apparatus
Technical field
The present invention relates to a kind of vacuum distillation plant, be specifically related to a kind of destilling tower washing section withdrawing oil distribution apparatus in petrochemical industry production.
Background technology
Extract at waste lubricant oil regeneration in the production process of lube base oil, first waste lubricating oil removes mechanical admixture, most water by sedimentation, then isolates remaining moisture through atmospheric distillation tower; The material removing mechanical admixture and moisture enters one-level destilling tower, isolates light diesel fuel; Material after one-level distillation enters the decompression distillation of secondary distillation tower, isolates distillate and vinasse, and distillate becomes lube base oil through refining, and sell as product after mediation, vinasse is as fuel.Filler condensation segment, padding washing section is provided with from top to bottom in secondary distillation tower.In order to ensure the rectifying quality of secondary distillation tower, must to the withdrawing oil of filler condensation segment, padding washing section spray proper temperature and flow.At present, conventional method respectively arranges a withdrawing oil distributor above filler condensation segment, padding washing section.Owing to being provided with two withdrawing oil distributors, must arranging two covers independently withdrawing oil heating and temperature control system, holding vessel, conveyance conduit separately, cause that the manufacturing expense of device increases, thermal losses rising, delivery pump quantity and power consumption be corresponding increase also.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of destilling tower washing section withdrawing oil distribution apparatus of oneself's supply is provided, rectifying quality can be improved, reduce production cost.
For achieving the above object, destilling tower washing section withdrawing oil distribution apparatus of the present invention, comprise destilling tower, also comprise withdrawing oil distributor, described withdrawing oil distributor is fixed on destilling tower on the inwall of upper end; Filler condensation segment is provided with below withdrawing oil distributor; Parallel to each otherly below filler condensation segment be provided with polylith flow distribution plate, described flow distribution plate is fixed on the sidewall of destilling tower; Flow distribution plate is provided with elongated slot, and by being arranged at, bolt in elongated slot is corresponding to be respectively fixed on polylith flow distribution plate multiple " L, " shape long slab, and the upper surface of flow distribution plate is not less than the upper surface of " L " shape long slab; Destilling tower inwall below " L " shape long slab is provided with the annular collecting tank of an opening upwards, is fixed on destilling tower inwall outside annular collecting tank, annular collecting tank inside upper part with " L, the two ends of shape long slab connect; What destilling tower sidewall and annular collecting tank surrounded is spatially provided with oil-out; Padding washing section is provided with below annular collecting tank.
Parallel clearance between described flow distribution plate and " L " shape long slab is 5 ~ 8mm.
Between described flow distribution plate and " L " shape long slab, difference in height is adjustable.
Described flow distribution plate is with a jagged lower surface.
The present invention compared with prior art has the following advantages:
(1) withdrawing oil needed for padding washing section is shunted by flow distribution plate and is obtained outside " L " shape long slab, realizes oneself's supply in padding washing section withdrawing oil tower, no longer needs to arrange separately withdrawing oil feed system, reduce equipment investment;
(2) reduce a set of withdrawing oil feed system, simplify production operation flow process, reduce production run expense, improve the reliability of plant running;
(3) between flow distribution plate and " L " shape long slab, difference in height is adjustable, by difference in height between adjustment long slab and flow distribution plate, can adjust the flow of withdrawing oil needed for padding washing section neatly.
(4) jagged lower surface on flow distribution plate, makes padding washing section withdrawing oil be uniformly distributed, improves clean result.
(5) padding washing section possesses the double action of washing and rectifying simultaneously, improves rectification efficiency.
