Description
Technical field
The utility model relates to vacuum distillation technique field, in particular a kind of thin based on separate heat pipeFilm evaporator.
Background technology
The full name of thin film evaporator is mechanical agitation type thin film evaporator, is called again thinfilm rotary evaporator. BeA kind of new and effective energy-conservation falling film evaporator. It stops with equipment heat transfer coefficient high (evaporation intensity is large), materialStay the superior performances such as short, applicable range of viscosities of time elasticity wide, operation is large, at chlor-alkali, chemical industry, lightThe industries such as work, food, pharmacy and environmental protection are widely used.
Its operation principle is as follows: material is forced film forming, thermal source by the stirring of rotor upper hanging plate after entering evaporimeterHeat carries out heat exchange through barrel and feed liquid, and liquid film boiling removes deentrainment through catching film device after indirect steam vaporizationDrop after discharge, concentrate is emitted by bottom discharge mouth. Therefore thin film evaporator has following characteristics:
1, have very high heat transfer coefficient, evaporation intensity is large, to water and organic solvent (viscosity is less than 100cp)Deng reaching 50～300kg/m2.h。
2, low-temperature evaporation: because thin film evaporator operates under vacuum, vacuum requires according to evaporant material propertyMatter is determined, greatly reduces the boiling point of material handling, and the low temperature that is therefore particularly suitable for heat sensitive material is concentrated. WithTime can select common material to process concentrated to strong corrosive medium.
3, the time of staying is short: material time of staying in equipment is very short, between several seconds～tens seconds. StopTime changes along with link plate surface groove inclination angle difference. Material, under the propelling movement effect of link plate, is in equipmentSpiral declines and leaves heating cylindrical shell, and material is extruded, and shortens the time of staying, can reduce product and evaporateDecomposition in journey or polymerization, the rate of recovery of raising solvent.
4, save the energy: owing to adopting vacuumizing, reduced material boiling point, before the identical temperature difference of guaranteePut, can utilize low-grade steam, saved the energy. The end effect evaporation of particularly suitable multiple-effect evaporation.
5, easy to operate, for ease of maintenaince maintenance: because rotor-support-foundation system has good stirring action to evaporation material,Equipment surface has minimum surface scale, can process high viscosity, containing particle, thermal sensitivity and easy Jie of crystallizationMatter.
But because its scheme adopting is the scheme of the quick heat exchange vaporization of a small amount of material, when material vaporization, need a large amount ofHeat energy, is limited by the restriction for thermal velocity, and the production capacity of thin film evaporator is restricted, and cannot further carryRise.
