A kind of forced circulation spraying evaporator
Technical field
This utility model relates to vaporizer technology field, is specifically related to a kind of forced circulation spraying evaporator.
Background technology
Evaporation is exactly the method with heating, the solution containing fixedness solute is heated to boiling situation, makes partial solvent vaporize and be removed, thus improves the unit operation of solute concentration in solvent.Commercial production is applied evaporation operation have following several occasion:
1. concentrating dilute solution is directly produced product or concentrated solution reprocessing (such as crystallisation by cooling) is produced solid product, the such as concentration of electrolytic caustic soda liquid, the concentration of sugar water solution and the concentration etc. of various fruit juice;
Concentrate solution the most simultaneously and recycling design, the such as concentration of organophosphorus pesticide benzole soln take off benzene, the evaporation etc. of ethanol leachate in Chinese medicine production;
3. in order to obtain pure solvent, such as desalinization etc..
In a word, in the industry such as chemical industry, food industry, pharmacy, evaporation operation is widely used.
The raw material (such as fruit jam, saccharide etc.) bigger for viscosity and the higher raw material of some de-water ratios are (such as Aqueous Solutions of Polyethylene Glycol, initial moisture content is 8%, after needing moisture removal, water content is less than 1%), when concentration is the highest, moisture evaporation separating difficulty is the biggest, when removing with traditional vaporizer, energy consumption is big, evaporation time is long, and operation is loaded down with trivial details, and processing cost is high.
