Abstract

The invention provides a vertical tube outer falling film evaporator. The vertical tube outer falling film evaporator comprises an outer shell, a material inlet channel is arranged at the top of the outer shell in a penetrating manner; a material outlet channel is arranged at the bottom of the outer shell; a distribution disc and a falling film evaporation unit are sequentially arranged in the outer shell in the downward direction of the material inlet channel; the falling film evaporation unit comprises a first tube plate, a second tube plate and at least one single-head heat exchange tube. In the use process of the vertical tube outer falling film evaporator, materials uniformly form a film on the outer surface of the heat exchange tube, so that the phenomena of scaling and blockage caused by evaporation in the heat exchange tube are solved, meanwhile, the flow area of the materials is also increased, and the pressure drop is reduced; in addition, gas channels are arranged between the heat exchange tube bundles in the vertical tube outer falling film evaporator, generated gas can be led out of the tube bundles, and the pressure drop of cold side fluid is further reduced.

Description

Technical field [0001] The present invention belongs to the field of evaporator, and more relates to a falling film evaporator, and more particularly to a vertical tubular filling film evaporator. Background technique [0002] The drowning membrane evaporator is widely used in water or organic solvent solutions in medicine, food, chemicals, light industry, etc., and can be widely used in waste liquid treatment in the above industry. The drowning film is particularly suitable for thermal materials, which can be continuously operated under vacuum low temperature conditions, with high evaporation ability, low energy saving, low operating cost, etc., and ensures that the material is invariant during evaporation. [0003] Currently, there is a common falling film evaporator type with all-in-tube evaporator and horizontal exhaustor, which is mainly based on vertical pipe evaporators. [0004] CN 209790898U discloses a horizontal tube filling film, the horizontal tube reflection film in...
