Abstract
The invention relates to a method for manufacturing a thin-layer multi-turn-surface evaporator. According to the method, conical evaporation surfaces are adopted, materials are uniformly distributed on the upper conical evaporation surface, and liquid flows downwards along the conical surface under the action of gravity, turns to enter the lower conical evaporation surface when flowing to the position close to the inner wall surface of the evaporator, flows downwards along the conical surface under the action of gravity, and turns to enter the next set of evaporation surfaces after flowing to a center distribution pipe and being gathered and redistributed; the process is repeated in this way till concentrated liquid at the kettle bottom is drained.
Description
Technical field
The invention belongs to the field such as separation process and environmental conservation.The present invention uses cone-shaped evaporating surface, and material is under gravity
Flow downward along the cone conical surface, form thin layer liquid film, to liquid film heating and under vacuum or normal heating state, in liquid
Volatile components is evaporated.Through repeatedly rolling over face evaporation, obtain the concentrated solution material that volatile components is the lowest.
Background technology
It is high viscosity liquid, high solids content suspension, high saline solns and high concentration liquid etc. that the present invention processes liquid, needs
Except the volatile component such as most of moisture, solvent in liquid, the most conventional technique has vacuum still distillation method and thin film evaporation
Method.Film evaporation method can use continuous operation mode, but either falling film type still rises membrane type, all has that energy consumption is high, equipment is multiple
Miscellaneous, auxiliary equipment is more, takes up space relatively big, moisture content and low-boiling point material is difficult to purify to less than 0.5%.Vacuum autoclave is steamed
The method that evaporates typically uses discontinuous operation pattern, uses chuck heating, agitator agitation material mode.The advantage of vacuum distillation method is
The intermittently operated time can control according to material degree of purification, it is possible to ensureing the water content of product, this technique is the most widely used
Method.The subject matter that this technique exists is, owing to unit heat transfer area, flat evaporator area are the least, to cause stirring greatly merit
Rate, high heat consumption；Owing to disengagement area is little, evaporation time is long, to the reaction of oxidation reaction, molecular chain rupture or contracting easily occur
Close reaction and thermal sensitivity biological material etc., often have a strong impact on product quality；Additionally the operation in gap is also difficult in adapt to advise greatly
Mould continuous prodution, the requirement of Stabilization Control.
Present invention flow principles based on high viscosity liquid, Mass and heat transfer are theoretical and distill principle, use ultrathin fluid layer technology,
Invent thin layer many folding surface technologies and the device of high volume pneumatization, thus realized ultrathin evaporation, augmentation of heat transfer, reduced
The time of staying, it is greatly increased unit volume disengagement area ratio, improves product quality, it is achieved the continuous and steady operation of process and product
Quality controls accuracy, and disposal ability is greatly improved.
