Description

Eddy flow flash distillation cloth-film formula heat pipe distiller that boils again
(1) technical field
The present invention relates to a kind of vacuum distillation plant, be specifically related to eddy flow flash distillation cloth-film that industries such as a kind of fine chemistry industry, pharmacy, food use formula heat pipe distiller that boils again.
(2) background technology
Distillation is usually used in the separation of each component in liquid-liquid or the liquid-solid mixture as a kind of thermodynamics separating technology.In traditional distillation process technology process, separated material causes its composition to be destroyed owing to being heated for a long time or Yin Gaowen causes chemical reactions such as molecular oxidation even cracking, polymerization; On using, be restricted; As: from vegetable oil and cod-liver oil, extract higher fatty acids, just can not use traditional distillation mode, and adopt mechanical knifing or the vacuum distillation of free falling-film formula; These two kinds of distillation modes are based on evaporating surface and form one deck thin evaporated film; Utilize in the separated material difference of boiling point between two-phase or multiphase, thereby reach the purpose of separation, these two kinds of distilling apparatus are generally used at present.See that from separating effect these two kinds distillation formal cause its materials are thicker at the rete of evaporating surface, heated time is long, evaporating temperature is high and the temperature distributing disproportionation weighing apparatus, be unfavorable for that some are prone to decompose, the separation of the heat sensitive material of oxidation.
Still-process needs the outside that thermal source is provided, and method at present commonly used is that the reduction of the heating agent (as: conduction oil) in chuck temperature release heat is come heat supply at distilling apparatus outer setting electric heater unit or on through distilling apparatus.Though electrical heating is convenient, has increased production cost, and can produce the hot-spot phenomenon, influences distillation procedure and product quality; The conduction oil heat supply belongs to the sensible heat heat supply, and heat flow density is lower, and the working ability of distiller is restricted.
(3) summary of the invention
To above-mentioned defective of the prior art, the invention provides a kind of evaporating surface rete is thin, the material heated time is short, Temperature Distribution is balanced, heat capacity improves, working ability significantly increases eddy flow flash distillation cloth-film formula heat pipe distiller that boils again.
Eddy flow flash distillation cloth-film of the present invention formula heat pipe distiller that boils again comprises an airtight cylinder, and the cylinder upper end is provided with vacuum interface, and the cylinder lower end is provided with the vinasse outlet; In cylinder vacuum interface below alternate two dividing plates with holes that match with barrel bore that are provided with, be provided with filler between two dividing plates; On the sidewall of the cylinder below the dividing plate, be provided with a light fraction outlet; On the madial wall of cylinder below the light fraction outlet, be provided with the annular collecting tank that an opening makes progress, annular collecting tank is fixed on the cylinder madial wall; On the madial wall of cylinder below the annular collecting tank, be provided with a feed nozzle, the direction of feed nozzle setting is the inboard tangential direction of cylinder; Feed nozzle top is provided with a ring baffle with the inboard, and the outer rim on ring baffle top is fixed on the cylinder madial wall, the ring baffle lower end to the inclination of cylinder madial wall direction and with cylinder madial wall retention gap; The outside of the cylinder 1 of an alternate segment distance is provided with the heat pipe heater around cylinder 1 in the ring baffle lower end.
The present invention compared with prior art has the following advantages:
(1) adopt tangential feed, the gas-liquid easy separation, and also the amount of liquid of carrying secretly is less, avoids liquid material to be evaporated gas and directly brings the light fraction outlet into; Material is atomizing and a large amount of fine droplets of formation rapidly, have increased considerably the heating surface area of material, have improved evaporation efficiency.
(2) charging aperture adopts nozzle arrangements, has accelerated the movement velocity of material, makes material move downward and be the very thin membranaceous distiller inwall that is covered with along the rotation of distiller inwall; Form turbulent flow during Flow of Goods and Materials easily, improved heat transfer efficiency; Material is evenly distributed, and has avoided dried wall phenomenon; The material that is prone to fouling in the material can not assembled because of receiving the shearing force effect, avoids producing scale formation at the distiller inwall.
(3) eddy flow flash distillation cloth-film formula heat pipe distiller that boils has again combined the big and effective advantage of thin film evaporation device separates of flashing apparatus evaporability; Single flash can be accomplished the evaporation task that needed flashing apparatus and falling film evaporation equipment to accomplish originally; Reduce equipment investment, improved production capacity.
(4) in the still-process, the material heated time is short, is heated evenly, evaporation rate is fast, avoided occurring coking phenomenon on the evaporating surface, is specially adapted to be prone to decompose, the separation of the heat sensitive material of oxidation.
(5) still-process institute calorific requirement is provided by the heat pipe heater; Heat pipe is to realize conducting heat through heat absorption and exothermic process that internal working medium state variation (liquid-vapour-liquid) causes, promptly utilizes the phase-change heat transfer of working medium, belongs to the latent heat heat supply; Heat flow density is than high 1～2 one magnitude of sensible heat heat supply; Heat capacity increases, and temperature equalization, stable can improve 1～2 times of the evaporability of equipment.
(4) description of drawings
Fig. 1 is eddy flow flash distillation cloth-film of the present invention formula heat pipe distiller structural representation that boils again.
(5) specific embodiment
According to a particular embodiment of the invention detailed description further sets forth the present invention below.
