Film evaporator is a type of evaporator, the wiped film evaporator characteristic is the material flow along the heat pipe wall is membrane fluid and heat transfer and evaporation, the advantages of high heat transfer efficiency, evaporation speed, the material stay time is short, so especially suitable for the evaporation of the thermal sensitive material. In the thin film evaporator selection, must consider various factors:
1, production capacity and operating parameters, including processing, in and out of the concentration, temperature, annual operating hours, etc.;
2, product characteristics, including thermal cbd crystallization equipment sensitive, viscosity and liquidity (in the operating temperature), the hair bubble, solid content, crystallization and orientation, etc.;
3, operating medium: water vapor (pressure), cooling water (temperature), cleaning fluid (solvent), etc.;
4, manufacturing materials selection and surface polishing requirements;
5, site conditions, such as space, climate (outdoor), energy, and the product of cohesion, working platform, etc.
Pervaporation membrane separation process is simple, mild operating condition, a high degree of automation, high safety and its operating process, more suitable for inflammable, explosive dehydration of solvent system.
Inorganic pervaporation membrane separation decarboxylation after extraction device the whole machine adopts modular design, practical and delicate, equipment capacity, easy maintenance. Compared with organic pervaporation membranes, inorganic pervaporation membrane with high flux, high temperature resistant, long service life, low total cost, etc. Our company can design and manufacture according to customer requirements, improve performance, convenient operation, high efficiency and energy saving, etc., and perfect after-sales service, users can rest assured to choose.
