Description
Technical field
The invention belongs to evaporator device technical fields, are heated evenly more particularly to one kind, and evaporation intensity is big, prevent from tying
Burnt luwa evaporator.
Background technology
The full name of thin film evaporator is mechanical agitation type thin film evaporator, also known as thinfilm rotary evaporator.It is a kind of
New and effective energy saving falling film evaporator.The range of viscosities that it is higher with equipment heat transfer coefficient, residence time of material is shorter, applicable
The superior performances such as wide, operation elasticity is big, obtain widely in industries such as chlor-alkali, chemical industry, light industry, food, pharmacy and environmental protection
Using.
Its operation principle is as follows：Material enters after evaporator forces film forming, heat from heat source by the agitation of rotor upper scraping plate
Heat exchange is carried out through barrel and feed liquid, liquid film boiling is discharged after indirect steam vaporization after catching drop of the diaphragm except deentrainment,
Concentrate is released by bottom discharge mouth.Therefore thin film evaporator has the characteristics that：
With very high heat transfer coefficient, evaporation intensity is big, to water and organic solvent（Viscosity is less than 100cp）Etc. reach 50~
300kg/m2.h。
Low-temperature evaporation：Since thin film evaporator operates under vacuum, vacuum level requirements are determined according to evaporation material properties, greatly
The big boiling point for reducing processing material, therefore it is particularly suitable for the low temperature concentration of heat sensitive material.Common material can be selected simultaneously
To handle the concentration to strong corrosive medium.
Residence time is short：Material residence time in equipment is shorter, between more than ten seconds~tens seconds.Residence time with
Hanging plate surface groove inclination angle is different and changes.Material is helically lowered away from heating under the push effect of hanging plate in equipment
Cylinder, material are squeezed out, and the residence time is shortened, it is possible to reduce decomposition or polymerization of the product in evaporation process improve solvent
The rate of recovery.
It is energy saving：Due to using vacuumizing, material boiling point is reduced, it, can be under the premise of ensureing the identical temperature difference
Using low-grade steam, the energy has been saved.The end effect of particularly suitable multiple-effect evaporation is evaporated.
It is easy to operate, for ease of maintenaince maintain：Since rotor-support-foundation system has good stirring action, equipment surface to evaporation material
With minimum surface scale, high viscosity can be handled, containing particle, thermal sensitivity and the medium easily crystallized.
But luwa evaporator feeding manner in the prior art, frequently with top feed, material is flowed from top down,
Causing material to concentrate on, top heated time is longer, and material is easy dry and hard.And the type of flow of material from the top down can also be made
At the uneven of each spot temperature of evaporator, the loss of thermal energy is caused.
Invention content
Present invention aims at uneven, easily dry and hard defect is heated for existing luwa evaporator, provide one kind by
Hot uniform, residence time of material is shorter, evaporation intensity is big, the luwa evaporator of slagging prevention.
The present invention to achieve the above object, adopts the following technical scheme that：
A kind of luwa evaporator, including evaporation cylinder, the transmission shaft of motor-driven rotation being arranged in the evaporative cylinder body are scraped
Plate, the scraper plate are connected to by scraper plate support on the transmission shaft, it is characterised in that：Different location is set in the evaporative cylinder body
Multiple feed distributors are equipped with, material sprays to the evaporation cylinder inboard wall through multiple feed distributors.
It is further characterized by：Multiple feed distributor settings are again on the transmission shaft；The transmission shaft and into
Expect that distributor is hollow, and is interconnected, cavity of the material through the transmission shaft and feed distributor, from the one of feed distributor
End sprays to the evaporation cylinder inboard wall.
Further：The feed distributor interval setting.
Further：Material inlet is located at the evaporation cylinder lower part, is connected with the bottom of the transmission shaft.
Preferably：The material inlet is connected with the transmission shaft by rotary joint.
Further：It is provided with umbrella shape distributor below each feed distributor.
Preferably：The umbrella shape distributor is two, is separately positioned in the scraper plate support below the feed distributor.
Two adjacent umbrella shape distributors mutually stagger.
It is provided with demister above the transmission shaft.
It is provided with filler and collecting tank below the demister.
There are multiple heating agent chucks on the evaporation cylinder.
Material of the present invention is used as material channel by hollow transmission shaft and feed distributor, material from evaporation cylinder not
It is sprayed with position so that the offer of material no longer concentrates on the top of evaporation cylinder, and material is more uniformly spread, material stop
Time also effectively shortens, slagging prevention.And the heating agent chuck of different location corresponds to the material spout of different location respectively so that each
The load of a heating agent chuck is more average, to ensure to evaporate cylinder each position temperature uniformity, effectively save
The consumption of the energy improves the evaporation efficiency and production capacity of equipment.
