China Multi Effect Falling Film Evaporator Falling Film Evaporator with Two or Three Effects Falling Film, Find details about China Evaporator, Falling Film Evaporator from Multi Effect Falling Film Evaporator Falling Film Evaporator with Two or Three Effects Falling Film
| Product Name | Multi Effect Falling Film Evaporator Falling film evaporator with Two or Three Effects Falling Film |
| Flow mode | Form a uniform film and flow from top to bottom |
| Process flow form | Downstream (parallel flow), countercurrent, mixed flow and advection |
| Feature | The equipment operates continuously under vacuum and low temperature conditions. It has high evaporation capacity, energy saving and consumption reduction, low operation cost, and can ensure the invariance of materials in the evaporation process. |
| Application | Falling film evaporator is widely used in the evaporation, concentration and concentration of water or organic solvent solution in medicine, food, chemical industry, light industry and other industries, and can be widely used in the waste liquid treatment of the above industries. It is especially suitable for heat sensitive materials. |
Main Characteristic
1.1 Heating time will be no more than 6 minutes. due to this heat sensitive material suit for short heating time, after four times continuing feeding and discharging in the plant will reach the requirement you want.
1.2. Tight construction, combining the production processing program. The equipment including preheating, realize both preheating and concentration two processing step by once. so that save energy and in case of dirty product, also decrease the occupied area of the plant.
1.3. Suit for material higher concentration and viscosity.
1.4. Saving heating steam. 0.1 MPa showed on the Pressure gauge.
1.5. Easy to clean, at site cleaning by washing liquid without dismantle.
1.6. Easy to operate, run at site.
1.7. Will not lose material.
Theory
Raw material will be distributed evenly in every evaporating pipe, at the function of gravity, flow downward form a membrane in the inner wall of evaporator. At the same time, heating steam will heat exchanged, so liquid membrane will evaporating under mostly any pressure, run in the same direction of secondary steam, so that accelerated liquid membrane flow speed, increase the effect of heat exchange and film formation, shorten the heating time, so it suit for heat sensitive material concentrated to a higher concentration. In order to insure the wet state of film formation and improve heat exchange effect, in premise of fixed heat exchange area, increase the heat exchange length is the best way, this also why falling film is long and thin.
