Wiped film evaporator is also popular as scraped film evaporator, falling film evaporator or thin film evaporator, it is specially desiged to evaporate, condense, decolor, trip, react, degas, deodorant the materials with high heating-sensitive and easy to oxidate.
You could use wiped film evaporator in medical, pesticide, oil and fatty chemical industry, fine chemical industry, commodity chemical industry, biology chemical industry,etc.
Wiped Film Evaporator Working Principle:
1.Material through the upward side of heating zone radial direction come into evaporator, then through distributing device distribute into heating surface of evaporator, and the rotating film scraped device let feedstock material into uniform liquid film, finally spiral push downward. During this process, rotating film scraped device promise continuously and uniformly letting the liquid film do high speed turbulence flow, and prevent liquid film coking and scaling during heating process, so as to improve overall coefficient. Light component through evaporation form steam so as to go up, then through gas liquid separator arrived into condenser, heavy component is discharged from the cone of evaporator bottom.
2.Unique distributing device not only could distribute the material to inner surface of evaporator uniformly, prevent material splashing in evaporator and sprinkle in steam flow, but also could prevent new charging material flash at this place, great help to remove the foaming, and let the material only evaporate along heating surface.
3.Centrifugal separator is customerized to scraped film evaporator according to material characteristics, separate the liquid drop which is contained in rise steam, and let it back to distributing device.
What can you do using wiped film evaporator:
1.Scraped film evaporator is widely used in heat exchange project, especially for heat sensitive material (short time) heat exchange, scraped film device is benefits for heat exchange, and through different scraped film device design, it could do complex products distillation.
2.Scraped film evaporator is good used for the purpose of evaporation & concentration, desolventizing, stripping, reaction, degassing, deodorant , etc., and have got excellent efficient in the below area:
1)Traditional Chinese medicine and western medicine: Antibiotics, sugar solution, tripterygium wildordii vines, astragalus root, etc. Methyl imidazole and single acrylic amine intermediates, etc.
2)Light food: fruit juice, gravy, pigment, essence, spices, enzymes, lactic acid, xylose, starch sugar, potassium sorbate.
3)Grease chemical: eggs phosphorus esters, VE, cod liver oil, oleic acid, glycerol, fatty acids, waste lubricating oil, alkyl indican, alcohol ether sulfate, etc.
4)Synthetic resin: polyamide resin, epoxy resin, paraformaldehyde, PPS (sebacic acid polypropylene ester), PBT, formic acid allyl ester.
5)Synthetic fiber: PTA, DMT, carbon fiber, polyethylene tetrahydrofuran, polyether polyol, etc.
6)Petrochemical: TDI, MDI, trimethyl hydroquinone, trimethylolpropane, sodium hydroxide, etc.
7)Biological pesticide: acetochlor, c grass amine, chlorpyrifos, furan phenol, widely consumed spirit, such as herbicides, pesticides, herbicides, in addition to mites agent.
8)Waste water: inorganic salt waste water, etc.
The advantages and your benefits of wiped film evaporator:
1.Small pressure losing.
2.Big diathermanous coefficient, high evaporating efficiency.
3.Low evaporating temperature.
4.Short heating time.
5.Strong adaptability, easy to operate.
Hope these infomations could help you to get a new highly effective evaporatorwhen you evaporate, condense, decolor, trip, react, degas, deodorant the materials with high heating-sensitive and easy to oxidate.Wiped film evaporator customize is provided, welcome contact with TOPTION to communicate your actual needs during research or produce.
