Film evaporator

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 [0001] The invention relates to an evaporator, in particular to a thin film evaporator. Background technique [0002] We know that at present, most of the evaporators used in the chemical, food, pharmaceutical and other industries are single-effect falling film evaporators, which are driven by a motor, and the central rotor drives the scraper and the distributor to rotate, and the material enters the evaporator from the feeding port. , after being evaporated and concentrated by the evaporator, the efficiency is low, and the evaporation efficiency is only 100Kg / m 2 h, and the continuity is not perfect. For large chemical enterprises, this kind of equipment cannot meet the requirements of high-efficiency continuous operation, and the concentration ratio that the single-effect evaporator can achieve is small, so it is not suitable for materials that require high concentration treatment. . Contents of the invention [0003] The technical problem to be solved ...
