The introduction of the falling film evaporator
The film evaporator units is made up of the evaporator, the vapor-liquid separator, preheater three parts and a dump separator.
Thin film evaporator is used for concentration dilute solution from Chinese and Western pharmaceutical,food, light industry, petroleum, chemical, environmental protection and so on.
the equipment has the character of large production capacity, high efficiency and short heating time, which more suitable for thermal sensitive raw materials in vacuum conditions.
Separation technology is one of the three major technologies in chemical production, and the quality of the separation process has a great impact on product quality, efficiency, consumption and benefits. High-efficient rotary thin film evaporator is a kind of equipment conducting the separation based on the volatility of different materials, with high heat transfer coefficient, low evaporation temperature, short material remain time, high thermal efficiency, and high evaporation intensity. It is widely used for evaporation, condensation, desolventization, purification, stripping, degasification and deodorzation in petrochemical, fine chemical, pesticide, food, pharmaceutical, and biological chemical industries.
Main Features of the falling film evaporator :
1) Material: the part touched with the raw material is stainless steel
2) Type: sliding scrapper
3) Evaporation area: 0.8 - 18M2
4) Evaporation rate: 100 - 2160 Kg/h
5) Degree of vacuum: 60KPa
Various specifications available according to per customer's requirements.
Application of the falling film evaporator
it is widely applied in heat exchange engineering. Especially to thermo-sensitive materials in short heat-exchanging time, WFE makes for heat exchanging and distilling to complex products by different designs.
It has been used in the following field by evaporating for concentration, solvent doffing, vapor extraction, reaction, off-gas and deodorization, etc. which achieves good effect:Medicines: antibiotics, sugar solution, tripterygium, radix astragali and other Chinese herbs; methylimidazole, mono-nitrilamine and other intermediates.
Light and food industry: fruit juice, meat liquor, pigment, essence, spice, enzymatic products, lactic acid, xylose, cotn sweetener and potassium sorbate, etc.
Lipid and daily chemicals: lecithin, VE, fish liver oil, oleic acid, glycerol, fatty acid, waste lubricant, alkyl-amylose glycoside and ether-alcohol sulphate, etc.
Composed resin: polyamide resins, epoxies resins, polyoxymethylene (POM), PPS, PBT, propylene formic acid ester.
Composed fiber: PTA, DMT, carbon fiber, poly-tetrahydrofuran and polyether of polyhydric alcohols, etc.
Petrochemicals: TDI, MDI, trimethyl-hydroquinone, trioxylmethyl propane and sodium hydroxide, etc.
Pesticide: herbicides such as acetochlor, proprochlor, chlorpyrifos, furan powder, and cartentrazone etc. insecticides, weedicides and acaricides.
Wastewater: wastewater contains abio-salts.
