Abstract
The utility model discloses a kind of internal-circulation type membrane molecular distiller, form primarily of dispersive element, vacuum chamber, liquid distribution trough, evaporating surface, circulation pipe, body, cryosurface and axial-flow pump, described dispersive element has vacuum chamber, vacuum chamber is arranged on liquid distribution trough, liquid distribution trough has evaporating surface, cryosurface is arranged on top on the right side of body, circulation pipe is arranged in the middle of body, is provided with axial-flow pump below circulation pipe.The beneficial effects of the utility model are: operating cost is low, and the evaporation rate improving mixed liquor is high, and distillation efficiency is high.
Description
Technical field
The utility model belongs to distillation technique field, is specifically related to a kind of internal-circulation type membrane molecular distiller.
Background technology
During the work of tradition falling-film still, feed liquid is entered by feed pipe, forms the liquid film upgraded continuously under gravity, and in seconds heated after distributor distribution along evaporating surface.Light component is overflowed by liquid surface and is flown to cryosurface, is flowed out after cryosurface is condensed into liquid by light fraction outlet, and remaining liquid is exported by heavy constituent and flows out.The separative efficiency of this type of molecular still is far above stationary molecular still, shortcoming is that the material on evaporating surface is subject to the impact of flow and viscosity and is difficult to be formed uniform liquid film, and liquid easily produces channel in decline process, even rollover phenomenon can be there is, the entrainment produced splashes on cryosurface sometimes, causes separating effect to decline.In addition, the liquid film relying on gravity to flow downward generally is in laminar condition, and mass transfer and heat transfer efficiency are all not high, cause distillation efficiency to decline.
Utility model content
The purpose of this utility model is to provide a kind of internal-circulation type membrane molecular distiller, to solve the deficiency existed in such scheme.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of internal-circulation type membrane molecular distiller, form primarily of dispersive element, vacuum chamber, liquid distribution trough, evaporating surface, circulation pipe, body, cryosurface and axial-flow pump, described dispersive element has vacuum chamber, vacuum chamber is arranged on liquid distribution trough, liquid distribution trough has evaporating surface, cryosurface is arranged on top on the right side of body, circulation pipe is arranged in the middle of body, is provided with axial-flow pump below circulation pipe.
Immediately below described body, centre position is provided with raffinate outlet.
The beneficial effects of the utility model are: operating cost is low, and the evaporation rate improving mixed liquor is high, and distillation efficiency is high.
