Abstract
The invention relates to a film evaporator which comprises a motor speed reducer, a material distributor, a rotor, a scraping plate, an evaporation tank I, an evaporation tank II and the like, wherein the rotor is driven to rotate through a motor after the rotation speed of the motor is reduced through the speed reducer; the scraping plate is driven to throw and adhere materials to the inner walls of the evaporation tanks so as to form films; the films on the inner walls can be heated through vapor passing through hollow positions between the inner and outer walls of the evaporation tanks, so that separation and concentration of the materials can be achieved. The film evaporator can be widely applied to industries such as chemical engineering, food and medicines, compared with a conventional film evaporator, the film evaporator has the characteristics that the energy consumption is small, the temperature of requested vapor is low, the purification rate is high, and the like, the production period is shortened, the production efficiency is improved, and the product quality is ensured.
Description
Technical field
The present invention relates to a kind of evaporimeter, specifically a kind of thin film evaporator.
Background technology
We know, at present, the evaporimeter great majority applied in the industries such as chemical industry, food, medicine are single-action falling film evaporators, driven by motor, drive scraper plate and distributor to rotate by center rotor, material enters evaporimeter by charge door, discharges after evaporator evaporation is concentrated, inefficiency, evaporation efficiency is only 100Kg/m
2h, and continuity is perfect not, and to large chemical complex, this kind of equipment can not meet the requirement of its high-efficiency and continuous operation, and the cocnentration factor that single effect evaporator can reach is little, is not suitable for the material needing highly enriched process.
Summary of the invention
Technical problem to be solved by this invention overcomes above-mentioned the deficiencies in the prior art, provides that a kind of energy consumption is little, evaporating temperature is low, purification degree is high under negative pressure state thin film evaporator.
The present invention's taked technical scheme that solves the problem is: a kind of thin film evaporator, is provided with motor reducer, material distributor, rotor, scraper plate, evaporator one, evaporator two, vavuum pump connector, steam inlet, steam (vapor) outlet, material inlet, discharging opening, it is characterized in that: rotor upper end is provided with motor reducer, lower end extends in material distributor, material distributor is connected with external vacuum pump by the vavuum pump connector which is provided with, material distributor interior lower end is provided with scraper plate, scraper plate is arranged on rotor, material distributor is provided with material inlet near the upper end of scraper plate, material distributor lower end is fixed with evaporator one and evaporator two successively, two evaporators are equipped with inside and outside two-layer, material distributor inside communicates with the internal layer of evaporator one and evaporator two, and scraper plate is near the inwall upper end of evaporator one, be hollow structure between the inside and outside wall of two evaporators, and outer wall be equipped with steam inlet and steam (vapor) outlet, be provided with discharging opening in the bottom of evaporator two.
The said scraper plate of the present invention has several.
The present invention is owing to taking said structure, scraper plate leaves turbulent area in periphery, so that material can be uniformly distributed on evaporator inwall, vavuum pump connects evaporator internal layer, ensure evaporator internal negative pressure, thus the requirement of vapor (steam) temperature is reduced, decrease energy consumption, evaporating temperature is low also ensure that each composition of material does not produce decomposition better.Meanwhile, compared to conventional evaporator, evaporation intensity of the present invention improves 40-60%, and shorten the heating material time, occupation area of equipment is little, and plant maintenance is simple and convenient.

Be labeled as in figure: 1. motor reducer, 2. material distributor, 3. rotor, 4. evaporate filling one, 5. evaporate filling two, 6. scraper plate, 7. vavuum pump connector, 8. discharging opening, 9. steam inlet, 10. steam (vapor) outlet, 11. material inlets.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As Fig. 1, shown in Fig. 2, the present invention relates to a kind of thin film evaporator, comprise motor reducer 1, material distributor 2, rotor 3, evaporator 1, evaporator 25, scraper plate 6, vavuum pump connector 7, discharging opening 8, steam inlet 9, steam (vapor) outlet 10, material inlet 11, rotor 3 upper end is provided with motor reducer 1, lower end extends in material distributor 2, material distributor 2 is connected with external vacuum pump by the vavuum pump connector 7 which is provided with, material distributor 2 interior lower end is provided with scraper plate 6, scraper plate 6 is arranged on rotor 3, material distributor 2 is provided with material inlet 11 near the upper end of scraper plate 6, material distributor 2 lower end is fixed with evaporator 1 and evaporator 25 successively, two evaporators are equipped with inside and outside two-layer, material distributor 2 inside communicates with the internal layer of evaporator 1 and evaporator 25, and scraper plate 6 is near the inwall upper end of evaporator 1, it is hollow structure between the inside and outside wall of two evaporators, and outer wall is equipped with steam inlet 9 and steam (vapor) outlet 10, discharging opening 8 is provided with in the bottom of evaporator 25.
When the present invention uses, motor drives decelerator, motor reducer output shaft rotor driven rotates, material adds equipment through material inlet, rotor turns drives and is arranged on the rotation of epitrochanterian scraper plate, carry out material distribution, material after distribution enters evaporator one and forms film and be attached to inwall, steam enters evaporator one from steam inlet outer, evaporator one is heated, low boiling point component volatilizees by differential pressure through the discharge of vavuum pump connector after heating, and the material after concentrated enters after evaporator two evaporates again and flows out from discharging opening.And the present invention can realize monitored over time, material inlet place connection traffic metering device, can detect mass flow in real time, and steam inlet place connects the vapor (steam) temperature that temperature measurement device to test flows into evaporator, vavuum pump place arranges vacuumatic measuring device, ensures the negative-pressure vacuum degree of evaporator inside.
The present invention can be widely used in, in the industries such as chemical industry, food, medicine, compared with single-action falling film evaporator, having energy consumption little, required vapor (steam) temperature is low, and evaporation intensity is large, purification rate high, shorten the production cycle, improve production efficiency, ensure that product quality.
