Abstract
A kind of baffle-less roll daubing type thin-membrane short-range distiller is characterized in that evaporating surface at distiller is to not establishing any liquid-blocking device between the condensing surface; Set up up and down cross section liquid blocking disk, make gas molecule can unhinderedly enter interior cooler, thereby improved distillation efficiency, can prevent that again drop from carrying secretly and polluted product.The present invention simplifies the structure, and has improved benefit, has saved expense, is applicable to chemical industry, high sensible heat in the pharmaceuticals industry, the separation and purification of higher boiling and high viscosity class material.The present invention is used for the refining and distilling of VE (200T/), yield per unit area 45kg/hm
2Heat dissipation 230kcal/hkg, vacuum 10Pa, yield surpasses 96%.
Description
The invention belongs to vacuum molecular distillation equipment.
Roll daubing type book film short-distance distiller is to use the gas molecule mean free path under different vacuum conditions, a kind of separation equipment that the different principle of its stroke is made.Be applicable to the separation of high sensible heat material, higher boiling and high viscosity substance, mainly contain two kinds of the WFE formula of Japan and the roll daubing types of West Germany LEYBOLD-HERAEUS GMBH at present, structure is similar substantially.Because of stroke distance from the evaporating surface to the condensing surface of the product indirect steam of this kind distiller is tens millimeters only, for preventing entrained drip polluted product purity in the product indirect steam, so all behind the roller that is provided with vertical retaining liquid/gas separator-promptly rolling dauber between evaporating surface and the condensing surface, vertical baffle is housed, separate to reach vapour-liquid, improve the purpose of separation accuracy.Practice shows, in still-process, the existence that vertically keeps off liquid/gas separator has increased the collision opportunity between the indirect steam gas molecule, makes the indirect steam capacity of returns increase, cause secondary cycle to handle the increase of liquid measure, thereby reduced the benefit of roll daubing type book film short-distance distiller.And mainly being, the entrained drip problem produces splash droplet institute extremely owing to roll the dauber two ends.The existence of vertical baffle also makes portion gas molecule stroke strengthen, thereby has increased the equipment vacuum requirements.
The objective of the invention is at deficiency of the prior art, a kind of improvement project is proposed, make that the indirect steam gas molecule in the molecular still can be with the fastest speed, under than the low vacuum condition continuously, seldom running foul of each other, ground is direct to be arrived condensing surface and is condensed into liquid rapidly, and eliminate drop and pollute, make distiller keep optimum state continuously.
The present invention is a kind of baffle-less roll daubing type book film short-distance distiller, and it is by variable speed drive 1, rotary distributing device 2, interior cooler 3, rolls dauber 4, heating jacket 5 and collecting tank 6 and constitute; Variable speed drive 1 is with rotary distributing device 2 and roll dauber 4 and link; The outside is a heating jacket 5, and the centre is interior cooler 3; Roll dauber 4 between heating jacket 5 and interior cooler 3, it is characterized in that the top and bottom of rolling dauber 4 are respectively arranged with cross section liquid blocking disk 7 and following cross section liquid blocking disk 8; At evaporating surface to no any vertical liquid-blocking device between the condensing surface.
The present invention is described in detail below in conjunction with accompanying drawing.
Figure one is a structure principle chart of the present invention.
Figure two is a kind of cross section liquid blocking disk schematic diagram of the present invention.
Wherein 1 is variable speed drive, and 2 is rotary distributing device, and 3 is interior cooler, and 4 for rolling dauber, and 5 is heating jacket, and 6 is collecting tank, and 7 and 8 are respectively upper and lower cross section liquid blocking disk.
When heating jacket 5 temperature of baffle-less roll daubing type book film short-distance distiller reach the predetermined work temperature, start vacuum system, make vacustat at desired conditions, open the charging valve, crude liquid is entered in the distiller from liquor inlet a; Start variable speed drive 1 simultaneously, make distributing device 2, up and down cross section liquid blocking disk 7 and 8 and roll dauber 4 and begin simultaneously to rotate by certain speed.Under the effect of distributing device 2, the crude liquid that enters distiller intersperses among on the evaporating surface of heating jacket 5 equably, and dirty along wall, forms uniform liquid book film, heat absorption evaporation, cooler 3 in being advanced in the gas of generation; Unevaporated liquid continues dirty, enters collecting tank 6 at last and discharges distiller.The gas heat release of cooler 3 condenses into liquid in entering, and c flows out by the fraction outlet.Roll dauber 4 in rotary course, constantly clear up wall, make feed liquid on evaporating surface, constantly form new liquid film, produce product indirect steam continuously.Since the present invention at evaporating surface to not establishing any liquid-blocking device between the condensing surface, make gas molecule can unhinderedly enter interior cooler and arrive condensing surface, thereby it is more reasonable on the structure, the characteristics that also more meet molecular clock, thereby improved the benefit of roll daubing type distiller greatly, realized purpose of the present invention.
When crude liquid arrives evaporating surface, because the initial liquid film that forms is thicker, and roll dauber 4 in rotary course, also rotation thereupon of the roller on it, under the action of centrifugal force that the roller rotation produces, the roller end forms the drop that splashes easily.Liquid also easily rolling the thicker liquid film of dauber lower end formation, can produce the drop that splashes equally in dirty process.If these drops are brought into interior cooler, just can polluted product purity.The present invention is respectively equipped with cross section liquid blocking disk 7 and following cross section liquid blocking disk 8 at the two ends of rolling dauber 4.Last cross section liquid blocking disk 7 is a L shaped cross section disk, be contained in distributing device 2 the lower edge, roll dauber upper end inboard or directly and distributing device 2 be designed to one, shown in figure two; Following cross section liquid blocking disk 8 is the T section disk, be contained in and roll inboard, dauber lower end, the cross section liquid blocking disk rotates with rolling dauber up and down, its effect is when rolling dauber 4 two ends when having drop to splash, the cross section liquid blocking disk can block and make droplet congregating on its outer surface up and down, the drop that the centrifugal force that produces when utilizing liquid blocking disk to rotate will be assembled gets rid of to get back to and rolls on dauber and the evaporating surface, thereby has overcome drop polluted product purity problem.
The invention has the advantages that the structure of both having simplified roll daubing type book film short-distance distiller, improved again the separation benefit, and can reduce device fabrication, maintenance and cost of use. Be adapted at the high sensible heat of separation and purification in chemical industry, the pharmaceuticals industry, higher boiling and high viscosity class material. Deodorization such as raw materials such as cosmetics, spices; Vitamin A, E's is refining etc.
The present invention is applied in the refining and distilling of vitamin E (200T/), heating surface (area) (HS 1.1m2, the distillation ability can reach 50kg/h, and yield per unit area is 45kg/h.m2; Per kilogram vitamin E distillation heat dissipation is down to 230kcal/h, vacuum 10Pa, and yield surpasses 96%; The finished product first-time qualification rate is more than 90%, realized carrying out under than the rough vacuum condition purpose of molecular clock, and indices all is higher than domestic and international same category of device. The VE product content that produces meets China and British Pharmacopoeia standard, and outward appearance look and other indices all reach the export trade standard.
