Description
Technical field
The invention belongs to the assembly on a kind of oil refining plant, specifically, relate in particular to a kind of double-deck distillation tower.
Background technology
An important technology of oil and fat refining is exactly depickling, the depickling of alkali refining method and physics refining method is arranged at present, because alkali refining method oil yield is low and produce too much waste water, waste residue, so the physical refining method is extensively adopted by industry.Physics refining method is exactly the principle lower than oil according to the lipid acid boiling point in the oil, and oil is heated, and adds vapor distillation, lipid acid is sloughed, and oil keeps.But,, be difficult to make processed oil to reach international one-level oil standard without alkali refining for the crude oil of acid value (AV＞6).This problem is the difficult problem that the industry colleague is badly in need of solution always.Double-deck distillation tower is a key component in the oil refining plant.Original old-fashioned extracting tower can only carry out a depickling to crude oil to be handled, and depickling is complete inadequately, tends to make olefiant waste.At present, also do not have a kind of deacid-deodoring combined column can satisfy the requirement of oil and fat refining better, can reach better and save raw-material purpose.
Summary of the invention
The purpose of this invention is to provide a kind of double-deck distillation tower, with solve in the prior art distillation deacidification effect relatively poor, can waste raw-material technological deficiency when producing.
The present invention adopts following technical scheme to realize: a kind of double-deck distillation tower, comprise tower body, and tower body is made up of last tower body and following tower body; Tower body top is provided with vacuum pump interface and oil inlet pipe, and the bottom is provided with oil outlet pipe, and tower body inside is provided with deacidifying device; Said deacidifying device comprises stuffing frame and hanger, and stuffing frame is fixed on tower body inside through support, and the top of stuffing frame is provided with filler, and the below is provided with sparging unit, and the top of filler is provided with oily distribution plate; The oil distribution plate is fixed on the tower body through hanger; Said sparging unit comprises steam inlet pipe and direct steam jet pipe; Said oily distribution plate comprises oily distribution plate housing, oil spill pipe; Oil spill pipe is fixed on the oily distribution plate housing; On oil spill pipe, be provided with the cross V-shaped part, on the edge suitable for reading of oily distribution plate housing, be provided with several V-notch, the bottom of oily distribution plate housing is provided with several oil leaking holes; Tower body inside is provided with two-layer deacidifying device, and the tower body between the two-layer deacidifying device is provided with down vacuum pump interface and oil drain pan, and oil drain pan is provided with down oil pipe.
Preferably be provided with joint flange and following joint flange on the tower body.
Compared with prior art, the invention has the beneficial effects as follows: 1, crude oil injects through oily distribution plate top, smooth outflow after distributing, and it is more even to make oil content join; 2, the setting of double-deck deacidifying device can be carried out double depickling to crude oil and handle, and has improved the output of oil refining, thereby has reached the purpose of avoiding waste of raw materials.
Description of drawings
