Technical field
A kind of slurry concentration technique field is the utility model is related to, more particularly to multiple-effect falling film is evaporated in vacuo condenser and set
It is standby.
Background technology
Evaporation is that the solution containing fixedness solute is heated under the conditions of boiling, makes partial solvent gasification for steam
Unit operates.Because solvent gasification needs substantial amounts of latent heat, therefore evaporation is the very high unit operation of an energy consumption.Multiple-effect evaporation
It is one of the most frequently used operating unit of process industrial, the indirect steam that preceding 1st effective evaporator vaporizes is passed through latter effect by multiple-effect evaporation
Heating steam of the heating chamber of evaporator as rear 1st effective evaporator, multiple-effect evaporation take full advantage of the vaporization of each effect indirect steam
Latent heat, it is a kind of evaporation operation of relative energy-conservation.
Downward film evaporator, elementary cell generally comprise heater and separator, and coordinate follow-up condenser to use, and are
Material liquid enters at the top of evaporator, is flowed downward with Action of Gravity Field along tube wall.Its operation principle is that falling film evaporation is to expect
Liquid adds from falling film evaporator heating chamber upper tube box, through liquid distribution and film formation device, is evenly distributed in each heat exchanger tube, and edge
Heat transfer tube wall flows down in uniformly membranaceous.During flowing down, by shell side heating medium heating vaporization, caused steam and liquid phase
The common separation chamber for entering evaporator, through being sufficiently separated, steam condenses vapour-liquid into condenser（Single-action operates）Or enter next
Evaporator is imitated as heating medium, so as to realize that multiple-effect operates, liquid phase is then discharged by separation chamber.
It is as follows using process：Material liquid is added by heating chamber top, downward along tube wall film-like after distributor is distributed
Flowing, gas-liquid mixture are discharged into separation chamber by heating bottom of the tube, complete liquid and are discharged by separation chamber bottom.Design and operate this
Planting the main points of evaporator is：Feed liquid is formed uniform liquid film in heating inside pipe wall as possible, and indirect steam can not be allowed by pipe
Scurry out at end.
Downward film evaporator can be used for evaporation viscosity larger（0.05~0.45Pas）, the higher solution of concentration, it is but uncomfortable
In the processing easily solution of crystallization and easy fouling, because to form uniform liquid film in distributor more difficult for this solution, conduct heat
Coefficient is not also high.
