Description
Technical field
This utility model relates to a kind of spin device, particularly to spin device in a kind of tower.
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, conventional stripper tower
Interior bucket is fixed, grease liquid after tower top sprays at the easy skewness of filling surface or become thread or walk short circuit,
The actually active theoretical cam curve making filler is reduced to about 60%；2, in order to there be enough contact exchange times, conventional vapour
Stripper must improve packed height, conventional packed height 5000～10000mm, and packed height is the highest, and the pressure drop of whole tower is more
Greatly, need to improve heating-up temperature at the bottom of tower to make free fatty vaporize, but when the vapourizing temperature of free fatty is more than 240 DEG C
Molecular cleavage can occur, produce unpleasant abnormal flavour, cause product defective.
Stripping packed tower should reduce tower packing height, keeps stripping separating effect again, if inside stripping packed tower
The liquid stream that rotatable words flow down from top of tower will be cut and dispersed into countless fine by atwirl filler metal silk screen
Drop, is formed vaporific, have greatly expanded the surface area of liquid, increases with the water vapour contact surface sprayed into from bottom, liquid middle reaches
Being easier to evaporation from fatty acid and dissolve in water vapour, the most vaporific ester liquid is covered with completely, and filling surface does not stay any dead angle, pole
Improve greatly the efficiency of filler, thus reach being completely separated of free fatty and grease.Packed tower internal rotating needs to drive
The device that dynamic tower internals rotates.Stripping packed tower is typically water vapour under being drawn of top vacuum and ramps up, and tower domestic demand is protected
Hold certain vacuum, and traditional machine driving sealing leakiness gas, this will have a strong impact on separation efficiency and product quality.Cause
This needs spin device in a kind of novel tower.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, it is provided that spin device in a kind of novel tower.Tool
Having the advantage saved the energy, there is not leakage problem, the technology that stripper efficiency is low, deacidification effect is poor solving routine is asked
Topic.
This utility model provides spin device in a kind of Novel tower, it include tower body, upper support frame, lower bracing frame, in
Mandrel, driving means；

Driving means includes impeller, steam jet；Impeller endoporus along the circumferential direction with flange, by bolt by flange with
Central shaft is connected；Steam jet is positioned at below impeller, sprays into steam and can make wheel rotation, and impeller drives central axis, thus
Tower inner core is driven to rotate；This utility model utilizes the water vapour that inherently can spray into be used as power and rotates bucket in tower thus drive and fill out
Material rotates, and more effectively utilizes steam, finishes the water vapour after merit and ascend into packing layer under being drawn of top vacuum pump,
Contact with ester liquid, rise together with free-fat azeotropic acid outside removal tower；And traditional machine driving sealing leakiness gas, impact
Separation efficiency and product quality.
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 85%-90% of a diameter of tower body diameter of impeller.
