Abstract
A kind of reextraction tower, including tower body, the raffinate outlet at the top of tower body is set and the Extract outlet of tower body bottom is set, tower body top is provided with solvent feed distributor, tower body lower part is provided with static mixer, and mixer outlet connects mixed liquor feed distributor；1-2 layers of random packing are provided in tower body between solvent feed distributor and mixed liquor feed distributor.The utility model mixes distillate and partial solvent first by mixer, come into full contact with distillate with solvent, complete preliminary extraction, the raffinate contact that the solvent and mixed liquor feed distributor sprayed again by the solvent feed distributor of tower top sprays carries out reextraction, further purifies to distillate.The extraction tower of the utility model is produced for waste mineral oil Reclaimed Base Oil, and packing layer may decrease to 1~2 layer, and can be reduced to 0.8~1:1 with oil ratio, save the energy consumption of solvent reclamation；Equipment investment 50% or so is reduced, and improves extraction efficiency and product quality.
Description
Technical field
The utility model belongs to chemical equipment technical field, is suitable for waste mineral oil regeneration production profit more particularly to one kind
The reextraction tower of lubricant base oil.
Background technique
Waste mineral oil regeneration production lube base oil generallys use vacuum distillation and isolates distillate from waste mineral oil,
Distillate obtains lube base oil after removing undesirable components by solvent extraction again.
Solvent extraction is one important process of waste mineral oil reclaimed lubricating oil base oil, is directly related to Reclaimed Base Oil
Quality and economic benefit.Since the viscosity of distillate is relatively high, for the removal effect for guaranteeing undesirable components in distillate, extraction
Deethanizer design it is relatively high, it is general to be not less than 20 meters, and Ta Nei also needs setting at least 4~5 layers of extraction tower filler special, every layer
2.5~3 meters of height of filler again need that redistributor is arranged under packing layer, lead to extract that tower structure is more complicated, high investment, fortune
The quantity of solvent being detained when row is big, increases operating cost.
Summary of the invention
The utility model aim is to deposit in waste mineral oil regeneration extraction process production process for existing extraction tower
Defect, provide that a kind of extraction efficiency is higher, effect of extracting is good, structure is relatively simple, cost relative moderate and energy-efficient
Reextraction tower.
The utility model to achieve the above object, adopts the following technical scheme that
A kind of reextraction tower, including tower body are arranged in the raffinate outlet at the top of the tower body and are arranged in the tower
The Extract of body bottom exports, it is characterised in that: the tower body top is provided with solvent feed distributor, and the tower body lower part is set
It is equipped with mixer, the mixer outlet connects mixed liquor feed distributor；The solvent feed distributor and mixed liquor charging
Filler is provided in tower body between distributor.
It is further characterized by: the mixer is static mixer.
Preferred: the filler is random packing.
The filler is 1-2 layers, and every layer of packed height is 2~3 meters.
The solvent feed distributor and mixed liquor feed distributor are pipe distributor.
The utility model mixes distillate and partial solvent first by mixer, comes into full contact with distillate with solvent,
The preliminary extraction of completion, then the raffinate of solvent feed the distributor solvent sprayed and the ejection of mixed liquor feed distributor by tower top
Liquid contact carries out reextraction, further purifies to distillate.The extraction tower of the utility model is for waste mineral oil regeneration basis
Oil production, packing layer can be reduced to 1~2 layer by 4~5 layers, and can be reduced to 0.8~1:1 by 1.5:1 with oil ratio, save
The energy consumption of solvent reclamation；Equipment investment 50% or so is reduced, and improves extraction efficiency and product quality.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
As shown in Figure 1, a kind of reextraction tower, including tower body 1, the raffinate outlet 2 and setting at 1 top of tower body are set
Extract in tower body bottom exports 3.1 top of tower body is provided with solvent feed distributor 4, and 1 lower part of tower body is provided with static mixed
Clutch 5, the outlet of static mixer 5 connection mixed liquor feed distributor 6；Solvent feed distributor 5 and mixed liquor feed distributor 6
For pipe distributor.1-2 layers of scattered landfill are provided in tower body 1 between solvent feed distributor 5 and mixed liquor feed distributor 6
Material 7, every layer of 7 height of random packing are 2~3 meters.
The mixer of above-mentioned reextraction tower, can also use pipe-line mixer, and the other forms such as eddy mixer are mixed
Clutch.Fillers selection can also using the structured packings such as grid packing, ripple packing, Impulse packing, can also using Pall ring,
The random packings such as cascade ring, Raschig ring.
The preferred static mixer of the utility model, since static mixer is a kind of mixing apparatus for not needing power, pipe
Without moving component in road.Its working principle, exactly allows fluid impact flow various types panel element in pipeline, increases fluid
The velocity gradient of laminar motion forms turbulent flow, and when laminar flow is " segmentation-position is mobile-converges again ", and when turbulent flow, fluid is except upper
It states outside three kinds of situations, violent vortex can be also generated in section direction, has very strong shearing force in fluid, makes fluid into one
Step segmentation mixing, is finally mixed to form required dispersion liquid.The above-mentioned characteristic of static mixer, for distillate and partial solvent
Be sufficiently mixed, tentatively extraction have good effect.
When utility model works, distillate and partial solvent are pumped to respectively in static mixer 5, in the short time rapidly
It is dispersed into micron-sized fine droplet, comes into full contact with distillate with solvent, completes preliminary extraction.Then by setting quiet
The tubular-mix liquid feed distributor 6 of 5 outlet end of state mixer sprays, and raffinate rises from tower bottom, with upper position in tower
The solvent contact of entrance carries out reextraction, further purifies to distillate；Extract produces recycling design from tower bottom, and circulation makes
With.
