Abstract
The utility model pertains to a fractionating tower used for producing essential oil of eucalyptus. A full condenser on the top of a falling film tower and a reflux distributor at the upper part of the tower are provided with a condensation return passage with a heat exchange area being 60-70 percent of a heating area; namely, the tube plate tray is evenly provided with a condensation passage tube bundle which is the same direction as that of the air flow direction of the tower; the pipe distribution area of the tube bundle is 40 percent of the tray area. The utility model keeps the original process conditions, reduces the volatilization of gamma-terpinene and p-cymene, improves the relative volatility of each component in the eucalyptus crude oil, leads the cineole content after one fractionation to reach over 80 percent with high resolution and low cost, thus avoiding the material consumption caused by additional devices and achieving good effects in the production.
Description
Technical field
The utility model belongs to the separation column of producing eucalyptus leaf essential oil.
Background technology
Cineole is important ring monoterpene oxide compound, 176 ℃ of boiling points, and normal temperature for colourless liquid, has the refrigerant fragrance of the camphoraceous intensive of class down.Have analgesic, antibacterial and anti-inflammation functions.Cineole content is about 60% in the eucalyptus oil that obtains behind steam distillation with eucalyptus leaves.Eucalyptus oil is as material outlet, and the content of cineole need reach more than 80%.Usually use and rise the membrane type separation column and once obtain cineole pure fevergum oil more than 80%.The phase weak point because Eucalyptus maideni is become a useful person, timber is good, the oil yield height, having replaced pure fevergum since the end of the eighties becomes the important source material that Yunnan produces eucalyptus oil.With Eucalyptus maideni distillatory folium eucalypti crude oil, α-Pai Xi content is obviously more on the low side than ethereal blue eucalyptus, and γ-Song Youxi and Paracymene obviously increase, these structural similitudies, molecular weight is close and boiling point differs very little plant chemical ingredient, in fractionation process, change along with molar fraction in the gas-liquid component, the relative volatility difference of each composition is too little, formed near azeotropic system, one time fractionation cineole content can only reach about 76%, is difficult to once obtain the eucalyptus oil of cineole content more than 80%.
Reduce that the content of γ terpinene and Paracymene once reaches more than 80% cineole content in the essential oil, or increase stage number and separation column is increased to minimum more than 1.5 times, be about to original 6 Mi Tajie be increased to more than 15 meters, become the equipment of bulky complex; Or with some section firpenes of the slow many amputation of super large reflux ratio, the time will prolong about one times, increase energy consumption and reduce efficient, also reduced flavouring essence quality.Before this, simple method is the essential oil that the first time, fractionation obtained is carried out fractionation once more or to convert with manually the fractionated high-content essential oil of pure fevergum being oozed.
Technology contents
The purpose of this utility model is intended to adapt to the continuous growth of eucalyptus leaf essential oil demand, a kind of existing equipment that do not change substantially is provided, reduce the volatile quantity of γ-Song Youxi and Paracymene by fractionation flow process, improve the relative concentration of cineole in the straight-bar fevergum crude oil, realize once promptly reaching the qualified product of cineole desired concn content in essential oil.
The utility model is realized in the following manner:
It is 60～70% condensing reflux path 10 6 of falling film heating device 101 that one joint heat interchanging area is set between cat head tubulation complete condenser 103 and distribution of reflux device 104, the condensation channel heat-exchanging tube bundle 106-4 consistent with the gas flow of tower promptly evenly is set on the tube sheet tower tray, and the stringing area of tube bank 106-4 is 40% of a tower tray 106-6 area.
And be provided with return line 106-5 at tube sheet tower tray 106-6 center.
When described tower diameter is 600mm, heat-exchanging tube bundle 106-4
32 number of tubes is the 150-220 root, and the length of pipe is (1～1.2) with the ratio of tower diameter simultaneously: 1.
The arrangement mode of described tube bank 106-4 on tube sheet tower tray 106-6 is equilateral triangle, square, or circular concentric.
In with upper type, because generally latus rectum will obviously increase less than 15% left and right sides packing tower pressure drop of tower diameter passage, so stringing area of the present utility model is not less than 40% of tray area.Secondly, heat interchanging area can maximum total resistance and the pressure drop of minimizing tower body between the 50-70% of heating-surface area, avoids energy consumption to raise.Once more, the condensing reflux passage is too short, and effectively transducing reduces the heat motion of gas molecules of γ-Song Youxi and Paracymene; The condensing reflux passage is long, with undercooling, also takes to unnecessary branch subconstiuent at the bottom of the tower, thus we this condensing reflux passage length is controlled at and tower diameter than between 1: 1～1.2.
As the applied separation column of the utility model, the recycle pump that is arranged at the bottom of the separation column still is transported to the film dispenser that places on the still with the eucalyptus oil of still, eucalyptus oil is flowed down to heating evaporation on the duct wall in the coupled thin-film evaporator with film like equably, constantly the mass transfer heat exchange is up up to cat head in the tower body filler for vaporized gas, the horizontal pipe bundle condenser of cat head all is condensed into liquid with gas, be transported in the reflux splitter a part of the derivation as product through collection; A part of thrust-augmenting nozzle is to the distribution of reflux device.This unit capacity is big, and control of reflux ratio can be near quantitatively control, and operation is simple and reliable, realizes control automatically easily.
The utility model has been obtained good effect with its outstanding advantage in the processing of eucalyptus oil essential oil.Facts have proved: this device has kept original processing condition substantially, r-terpinene and Paracymene are easy to the enrichment that is liquefied in this process, reduced γ-Song Youxi greatly and to the volatilization of Paracymene, big portion γ-Song Youxi, p-cymene hydrocarbon are enriched in the pin oil, improved the relative volatility of each component in the straight-bar fevergum crude oil, make a fractionation as a result cineole content all between 80～83%, improve the content of cineole in essential oil effectively, guaranteed the first-time qualification rate of eucalyptus leaf essential oil.Improved eucalyptus oil separation column efficient, reduced cost and energy consumption, the material of having avoided facility investment to cause expends.
