Abstract
The invention relates to an efficient continuous thin film evaporator. The evaporator comprises a motor reducer, a material distribution device, a rotor, a scraper blade, an evaporation tank I, an evaporation tank II, etc. After being slowed down by the motor reducer, motor rotates to drive the rotor to rotate, the rotation of the rotor drives the scraper blade to throw materials at the inner walls of the evaporation tanks to form thin films; when steam passes through the hollow space between the outer walls and the inner walls of the evaporation tanks, the thin films on the inner walls are heated, and the separation and concentration of the material are achieved. The efficient continuous thin film evaporator can be widely used in industries such as chemical engineering, food, medicines and the like. Compared with a conventional thin film evaporator, the efficient continuous thin film evaporator has the characteristics of small energy consumption, low required steam temperature, high purification rate, shortened production cycle and the like, improves production efficiency, and ensures product quality.
Description
Technical field
The present invention relates to a kind of evaporimeter, specifically a kind of high-efficiency and continuous thin film evaporator.
Background technology
We know, at present, the evaporimeter great majority of using in the industries such as chemical industry, food, medicine are single-action falling film evaporators, by motor-driven, drive scraper plate and distributor rotation by center rotor, material enters evaporimeter by charge door, discharges after evaporator evaporation is concentrated, inefficiency, evaporation efficiency are only 100Kg/m
2H, and continuity is perfect not, and to large chemical complex, this kind equipment can not satisfy 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 that needs highly enriched processing.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of energy consumption is little, evaporating temperature is low, the high high-efficiency and continuous thin film evaporator of purification degree under negative pressure state.
the present invention addresses the above problem the technical scheme of taking: a kind of high-efficiency and continuous thin film evaporator, be provided with motor reducer, the material distributor, rotor, scraper plate, evaporator one, evaporator two, the vavuum pump connector, the steam inlet, steam (vapor) outlet, material inlet, discharging opening, it is characterized in that: the rotor upper end is provided with motor reducer, the lower end extends in the material distributor, the 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, the 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, the material distributor is inner to communicate with the internal layer of evaporator one and evaporator two, and scraper plate is near the inwall upper end of evaporator one, it is hollow structure between the inside and outside wall of two evaporators, and be equipped with steam inlet and steam (vapor) outlet on outer wall, bottom at evaporator two is provided with discharging opening.
The said scraper plate of the present invention has several.
The present invention is owing to taking said structure, scraper plate has reserved turbulent area in the periphery, so that material can be uniformly distributed on the evaporator inwall, vavuum pump connects the evaporator internal layer, guarantee the evaporator internal negative pressure, thereby the requirement to vapor (steam) temperature reduces, and has reduced energy consumption, and evaporating temperature is low has guaranteed better that also each composition of material does not produce decomposition.Simultaneously, than conventional evaporator, evaporation intensity of the present invention has improved 40-60%, has shortened the heating material time, and occupation area of equipment is little, and plant maintenance is simple and convenient.
