Abstract
The utility model relates to a short distillation-range film evaporator, which belongs to the field of film evaporators. The short distillation-range film evaporator comprises an evaporator hood; a heat carrier oil inlet is formed on one side of the bottom end; heat carrier oil outlets are formed in the inner part, the middle part and the bottom part; and a spiral draft tube is arranged on the external wall of the evaporator; a galvanic couple tube is arranged in the evaporator and communicated with the outside of the evaporator; a cavity for evaporating raw materials is formed between the evaporator and a cooling hood; a heavy fraction outlet is formed at the bottom end of one side of the evaporator, which is close to the spiral draft tube, and is provided with a baffle; a light fraction outlet is formed at the bottom end of one side close to the cooling hood, and is provided with a baffle; and the spiral draft tube is in a double-layer spiral structure and close to the evaporator hood. According to the utility model, due to adoption of vacuum distillation, the cut liquid can be separated under a middle or low temperature, so that the short distillation-range film evaporator particularly plays a special role for the industry of pharmacy and the like, and can separate the liquid under a relatively low temperature and prevent the materials from being decomposed and oxidative deterioration due to high temperature, thereby being suitable for subdividing of fractions in small scale; and the equipment flexibility is strong.
Description
Technical field
The utility model relates to a kind of short boiling range thin film evaporator, and it belongs to the thin film evaporator field.
Background technology
Thin film evaporator is a kind of type of evaporimeter, and to be feed liquid be membranaceous flowing and conduct heat and evaporate along the heating tube wall characteristics, and advantage is that heat transfer efficiency is high, and evaporation rate is fast, and residence time of material is short, so is particularly suitable for the evaporation of heat-sensitive substance.In organic chemical industry and petroleum industry, answer arts demand often will cut or purify, and compound or fraction thing are carried out rectifying again
by molecular weight distribution fraction liquid.Traditional rectifying column or vacuum distillation tower, since in large scale, complex equipments, and operating difficulties is not suitable for middle-size and small-size production.
Summary of the invention
In view of the defective that prior art exists, the purpose of the utility model is to provide a kind of short boiling range thin film evaporator, available temperature separating liquid of trying one's best low relatively, and avoid material pyrolytic and oxidation deterioration.Control is fit to middle-size and small-size and precision production demand easily, also can repeat cutting for reaching the high precision cutting, and make fraction narrower, has adapted to the demand of product and technology.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: short boiling range thin film evaporator; It has the cooling dome of a setting, the feed(raw material)inlet that is used for medium to be evaporated that in the upper area of cooling dome, is provided with, connects the vacuum orifice of vacuum unit, sees window and coolant outlet; Evaporimeter in the cooling dome is an one by the high pressure flange sealing and fixing, and it is characterized in that: said cooling dome has sandwich; By cooling dome inwall and cooling dome closed front cooling water, the cooling water inlet is arranged at the cooling dome bottom; Said evaporimeter has the evaporimeter cover, and bottom one side has the heat medium oil inlet, and inner middle part has the heat medium oil outlet to the bottom, evaporimeter outer wall design spiral stream guidance tube.Evaporimeter indoor design galvanic couple pipe is connected to outside the evaporimeter.Be the cavity of vaporize before said evaporimeter and the cooling dome, be the heavy fraction outlet near the spiral stream guidance tube one of which side bottom of evaporimeter, and have baffle plate, be that light fraction exports near cooling dome one of which side bottom, and have baffle plate.Said spiral stream guidance tube is the double-layer spiral structure, is close to the evaporimeter cover.
After adopting such scheme; Compared with prior art has following beneficial effect: owing to adopted vacuum distillation; Be cut liquid and make, also can separate under the middle low temperature, especially industries such as pharmacy are had Special Significance; Available temperature separating liquid of trying one's best low relatively, and avoid material pyrolytic and oxidation deterioration.Be suitable on a small scale, subfraction, the equipment flexibility is strong.

The specific embodiment
For understanding short boiling range thin film evaporator in depth, explain as follows in conjunction with Fig. 1:
Short boiling range thin film evaporator; It has the cooling dome 7 of a setting, the feed(raw material)inlet that is used for medium to be evaporated 3 that in the upper area of cooling dome 7, is provided with, connects the vacuum orifice 1 of vacuum unit, sees window 17 and coolant outlet 2; Evaporimeter 15 in the cooling dome 7 is an one by the high pressure flange sealing and fixing, and said cooling dome 7 has sandwich; By cooling dome inwall 5 and cooling dome outer wall 6 sealing cooling waters, cooling water inlet 13 is arranged at cooling dome 7 bottoms; Said evaporimeter 15 has evaporimeter cover 4, and bottom one side has the heat medium oil inlet, and inner middle part has heat medium oil outlet 11 to the bottom, evaporimeter 15 outer walls design spiral stream guidance tube 16.Evaporimeter 15 indoor design galvanic couple pipes 14 are connected to outside the evaporimeter 15.Before said evaporimeter 15 and the cooling dome 7 be the cavity of vaporize, is heavy fraction outlet 12 near the spiral stream guidance tube 16 one of which side bottoms of evaporimeter 15, and has baffle plate, is that light fraction exports 9 near cooling dome 7 one of which side bottoms, and has baffle plate.Said spiral stream guidance tube 16 is the double-layer spiral structure, is close to evaporimeter cover 4.
Raw material directly through the heating body drop film evaporation of the film evaporator that falls, evaporates light fraction.Is to flow into recipient through two paths and steam liquid with steaming surplus liquid; And be split up into the material of acceptance is emitted,, be cut liquid and make owing to adopted vacuum distillation; Also can separate under the middle low temperature; Especially industries such as pharmacy there is Special Significance, available temperature separating liquid of trying one's best low relatively, and avoid material pyrolytic and oxidation deterioration.Be suitable on a small scale, subfraction, the equipment flexibility is strong.
