Abstract
The invention discloses a molecular distiller. The molecular distiller comprises a motor, a barrel body, a heating jacket, and a condenser and a film scraping device, wherein a liquid inlet is formed in the side wall of the barrel body; the heating jacket is located on the outer side of the barrel body; the condenser and the film scraping device are arranged in the middle of the barrel body; the film scraping device is driven by the motor and is arranged in the barrel body to be close to a barrel wall; a distillate collection groove is formed under the condenser; residual liquid collection grooves are formed in the two sides of the distillate collection groove; the molecular distiller is characterized in that a half pipe is arranged on the inner wall of the barrel body at the upper end of the film scraping device; a plurality of small holes are formed in the bottom of the half pipe; and the liquid inlet is communicated with the half pipe. According to the improved molecular distiller provided by the invention, the half pipe is arranged on the inner wall of the barrel body and the small holes are formed in the bottom of the half pipe, so that materials can be uniformly distributed and the separation efficiency is effectively improved.
Description
Technical field
The invention belongs to chemical separating apparatus field, specifically a kind of molecular still.
Background technology
Molecular clock also claims short-path distillation, is a kind of liquid-liquid isolation technics of carrying out in high vacuum conditions.Have vapo(u)rizing temperature low, system vacuum is high, and material heated time is short, separation degree high; And separation process is irreversible, bubbling phenomenon of not seething with excitement.Be specially adapted to be separated higher boiling, thermal sensitivity and easily oxidized material, be widely used in pharmacy, the fields such as food flavor.
Molecular still is the key equipment of molecular distillation technique, is mainly divided into: falling-film still, wiped-film still centrifugal molecular distillator.Scraped film type is a kind of molecular still form most widely used at present, and it is the effective improvement to falling-film still, is the intervention of blade applicator with the maximum difference of falling film type.It is even that feed liquid is spread to thickness by blade applicator on evaporating surface, the eddy current liquid film upgraded continuously, and greatly strengthen mass-and heat-transfer efficiency and effectively control thickness of liquid film, uniformity and residence time of material, distillation efficiency is significantly improved, and thermal decomposition significantly reduces.But the ubiquitous problem of wiped-film still is material skewness on evaporation wall at present, this is because material enters from evaporimeter side, evaporation wall is thrown to through liquid distribution trough, then material helically moves downward in the effect of Action of Gravity Field and rotating scraped film device, just evaporation wall is thrown to because material stops very short time on distributor, the material causing the second half to throw to evaporation wall reduces, and can not make full use of evaporating surface, separative efficiency is low.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of molecular still of improvement, material being evenly distributed, effectively improving separative efficiency.
The present invention is by the following technical solutions:
A kind of molecular still, comprise motor, sidewall is provided with the cylindrical shell of inlet, is positioned at the heating jacket outside described cylindrical shell, is positioned at the condenser in the middle of cylindrical shell and blade applicator, described blade applicator is driven by motor and is located in cylindrical shell near barrel, be provided with distillate feeder below described condenser, described distillate feeder both sides are provided with raffinate feeder, are provided with semicanal at the cylinder inboard wall of described blade applicator upper end, multiple aperture is provided with, described inlet and semicanal UNICOM bottom described semicanal.
Described molecular still is connected with degas system by inlet, and described degas system is connected with stoste holding vessel.
Advantageous Effects of the present invention: molecular still of the present invention is provided with semicanal at cylinder inboard wall, the stoste entered from inlet is gathered, by the aperture bottom semicanal, liquid is faced down along evaporation wall and stay, under the effect of blade applicator, material is evenly distributed, improves separative efficiency.Its heat time in distiller can be shortened after liquid in head tank is carried out preheating, improve distillation efficiency.Be that material is first degassed before entering distiller by degas system, and then ensure the condition of high vacuum degree in distiller.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further described, but protection scope of the present invention is not limited thereto.
As depicted in figs. 1 and 2: a kind of molecular still, comprise motor 1, sidewall is provided with the cylindrical shell 2 of inlet 3, be positioned at the heating jacket 4 outside described cylindrical shell 2, be positioned at the condenser 5 in the middle of cylindrical shell 2 and blade applicator 6, described blade applicator 6 is driven by motor 1 and is located in cylindrical shell 2 near barrel, distillate feeder 7 is provided with below described condenser 5, described distillate feeder 7 both sides are provided with raffinate feeder 8, semicanal 9 is provided with at cylindrical shell 2 inwall of described blade applicator 6 upper end, multiple aperture 10 is provided with, described inlet 3 and semicanal 9 UNICOM bottom described semicanal 9.
Described molecular still is connected with degas system 11 by inlet 3, and described degas system 11 is connected with stoste holding vessel 12.
Advantageous Effects of the present invention: molecular still of the present invention is provided with semicanal at cylinder inboard wall, the stoste entered from inlet is gathered, by the aperture bottom semicanal, liquid is faced down along evaporation wall and stay, under the effect of blade applicator, material is evenly distributed, improves separative efficiency.Its heat time in distiller can be shortened after liquid in head tank is carried out preheating, improve distillation efficiency.Be that material is first degassed before entering distiller by degas system, and then ensure the condition of high vacuum degree in distiller
The course of work: open condenser 5, simultaneously by heating jacket 4 pairs of barrel heating, feed liquid enters in the semicanal 9 in distiller under vacuum conditions, make liquid dirty along inwall by the aperture 10 under semicanal 9, utilize the rotation of blade applicator 6, on inwall, liquid is launched into film rapidly simultaneously, and move downward and fully contact with evaporating surface, heated wall constantly heats makes more volatile composition (distillation) gather very near built-in condenser 5 surface of distance, light component material is collected by distillate feeder 7, not volatile composition (heavy constituent material) returns in the process on liquid film surface and flows out from raffinate feeder 8 simultaneously, thus by light component and heavy constituent separating substances, the distillation separated is flowed out by distillate outlet.
Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, and to not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
