Description
Technical field
This utility model relates to device in a kind of rotatable tower, built-in particularly to a kind of rotatable tower for stripper
Put.
Background technology
Fatty acid ester is of many uses.Such as, biodiesel (a kind of alternative fuel) comprises ester (such as fatty acid methyl ester, fat
Fat acetoacetic ester etc.).The ester of some low-molecular-weights is volatile, has pleasant abnormal smells from the patient, and this makes them useful as virtue
Pastil or flavoring agent.Fatty acid ester is used also as the solvent of lacquer, paint, varnish etc..Ester is also used as in resin and plastics
Softening agent, plasticizer, fire retardant and the additive in gasoline and oil.Additionally, ester can be in polymer, thin film, weaving
The manufacture of product, dyestuff and medicine uses.Therefore, fatty acid ester is highly useful in this day and age.
Fatty acid ester can extract from oil.But the power consumption of this method is high and expensive.Further, frequent cracking base oil
In long chain hydrocarbon to produce the method that less monomer is poor efficiency.Then to be used as raw material more complicated to manufacture for these monomers
Speciality chemical.This method of cracking gasoline or oil is environmentally harmful.Due to these parent materials cost with
Oil price is linked up with, and the growth along with oil price is also increased by the cost therefore preparing these fatty acid esters.
Owing to oil extraction exists the risk of environmental disruption, therefore the now widely used method of the production of fatty acid ester is
Utilize the fatty acid monomer and alkylol (such as methanol, ethanol, isopropanol, butanol, isooctanol etc.) ester extracted from vegetable and animals oils
Change, then make through the operation such as deacidification, deodorize.Such as conventional fatty acid methyl ester, ten tetracosanoic acid isopropyl esters, 16 stearic acid isopropyls
Ester, different monooctyl ester, butyl oleate, different monooctyl ester etc. can be made by the method.
After fatty acid and alkylol esterification terminate, the most a small amount of free fatty exists, and free fatty can be serious
Affect the storage stability of grease and use quality, the problem such as low in tapinoma-odour, smoke point.Therefore the content of free fatty is subject to
Strict control, especially for the skin care item of contact human skin, be used for adding in high-end lubricating oil oleate etc., its trip
Require less than 0.1% from content of fatty acid.So deacidification is one of the most crucial technique in process of production, free fatty
De-unclean, directly affect the quality of ester product, it is impossible to be applied in downstream product.
At present, lipin deacidifying technique both domestic and external chemical deacidification method from original alkali refining develops into the thing of rectification under vacuum
Reason deacidification method.The outstanding advantages of physical deacidification method is: concise in technology, and without waste water, oil yield is high, good product quality.Physics takes off
Acid system utilizes the boiling point of free fatty to carry out deacidification less than the boiling point of fatty acid ester, and its nucleus equipment is stripping packed tower, oil
Ester liquid enters from top of tower, and grease liquid moves down in the effect of gravity, and water vapour sprays into from tower bottom, taking out at top vacuum
Under drawing, water vapour ramps up.Water vapour and grease liquid continue through the space of packing layer in adverse current, contact at filling surface, oil
Free fatty in ester liquid is issued to boiling point, vaporization at high temperature, high vacuum state and fuses azeotropic with water vapour, flows to tower top
After condensation outside removal system, reach deacidification purpose；The grease that boiling point is high continues the product after moving down as deacidification.
In order to effectively remove the free acid in product, vehicle repair major not only wants surface to be fully contacted, and frequency of exposure is more
Many, free fatty is more easily separated from grease.But existing physical deacidification law technology there is problems in that
1, in conventional stripper tower, bucket is fixed, and grease liquid easily divides at filling surface after tower top sprays into
Cloth is uneven or becomes thread or walks short circuit, makes the actually active theoretical cam curve of filler be reduced to about 60%；
2, in order to there be enough contact exchange times, conventional stripper must improve packed height, and conventional filler is high
Degree 5000～10000mm, packed height is the highest, and the pressure drop of whole tower is the biggest, needs to improve heating-up temperature at the bottom of tower and makes free fat
Fat acid vaporizes, but when the vapourizing temperature of free fatty is more than 240 DEG C, molecular cleavage can occur, and produces unpleasant abnormal flavour, causes
Product is defective.
So tower packing height should be reduced, keep stripping separating effect again, a kind of novel stripping need to be developed and fill out
Material Ta Tanei device.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, it is provided that a kind of in the rotatable tower of stripper
Device.There is rotatable advantage, solve the technical problem that stripper efficiency is low, deacidification effect is poor of routine.
This utility model provides a kind of device in the rotatable tower of stripper, is positioned at inside tower body, and it includes
Bracing frame, lower bracing frame, central shaft and tower inner core；
Upper support frame and lower bracing frame are provided with the centre bore supporting with central shaft, extended stabilizer centered by centre bore,
Leg end is weldingly connected with tower body；Central shaft is connected by ball bearing with upper support frame and lower bracing frame；
Tower inner core includes cylinder, middle packing material metal gauze, the cover plate for sealing, the base plate for support；
Described cover plate and base plate are annular perforated plate, and percent opening is 40%-66%, preferably 50%-60%；Its endoporus and outer shroud along
Circumferencial direction is with flange；By bolt, cover plate is connected with central shaft and cylinder with the flange of base plate, thus by whole tower
Bucket connects on center shaft；In tower, bucket is between upper support frame and lower bracing frame.In tower of the present utility model, bucket can rotate,
The liquid stream flowed down from top of tower is cut and dispersed into countless fine droplets by atwirl filler metal silk screen, is formed vaporific,
Have greatly expanded the surface area of liquid, increase with the water vapour contact surface sprayed into from bottom, in liquid, free fatty is easier to
Evaporating and dissolve in water vapour, the most vaporific ester liquid is completely covered, and filling surface does not stay any dead angle, greatly improves filler
Efficiency, thus reach being completely separated of free fatty and grease.The cover plate of the present invention and base plate are annular perforated plate, perforate
Rate is 40%-66%, preferably 50%-60%, and percent opening is the least, affects the flowing of material, and percent opening is too big, affects the steady of device
Solidity.
The bolt being connected between cylinder with cover plate or base plate is no less than 8.
Upper support frame, the leg of lower bracing frame are 3-6 root.
The blade of impeller is 8-12 leaf.
A diameter of 0.6 meter-2 meters of tower body.The 95%-97% of a diameter of tower body diameter of tower inner core.The diameter of tower inner core is little
In tower body diameter, it is meant that there is gap in tower between bucket and tower body, such that it is able to bucket can rotate in tower body in realizing tower.Seam
Gap can not be the least, the least if in tower bucket rock and may bump against tower body thus produce danger；Gap can not be too big, too greatly
The material that top sprays into directly may fall from gap, and does not has the cutting of filled metal gauze, atomization, thus results in and water
Steam is insufficient contact, thus causes free fatty not separate completely, causes product quality defective.This utility model controls
The 95%-97% of a diameter of tower body diameter of tower inner core, gap both will not too small also will not be excessive, product deacidification effect is good, produce
Quality is high.
In tower, bucket packed height is 2500-3500mm.
