Description
Technical field
The utility model relates to a kind of chemical industry equipment, is specifically related to a kind of falling film evaporation device of liquid material.
Background technology
The concentration process that often relates to reactant liquor or extract in chemical industry, medical product research, production, this concentration process normally carries out in a kind of evaporimeter, and falling film evaporation device is considered to an efficient evaporation concentration device.The efficiency of utilization of this type of falling film evaporator and production efficiency depend on the film forming situation of solution to be concentrated on falling film evaporator tubulation inwall.Film forming is more even, and the thermal efficiency is just higher.The uniformity of film forming depends mainly on again the structure of filming device, has reported various types of falling film evaporation devices, all in the structure of filming device, improves.But existing filming device all adopts a substandard cloth film or two substandard cloth films, actual conditions are the effects due to liquid cohesive force, the liquid of film forming can reassemble into drop and drip along tubulation middle part in descending process, thereby affects the efficiency of film forming, thereby has reduced the thermal efficiency and production efficiency.
Summary of the invention
Not enough based on prior art, the utility model object is to provide a kind of can further improve into film uniformity, thereby further improves a kind of falling film evaporation device of the thermal efficiency and production efficiency.
For realizing the utility model object, falling film evaporation device described in the utility model comprises by the connected upper cover of flange, lower cover, body, forms cylindrical shell.Upper cover upper end is provided with charging aperture, and bottom connects distributing disc; Body one side being positioned under distributing disc is provided with vaporium, and vaporium is connected with steam inlet, and lower cover top one side is provided with exhaust outlet, lower cover top opposite side is provided with bleeding point, and lower cover bottom is provided with discharging opening.Distributing disc is provided with a plurality of chargings aperture, and each lower end, charging aperture connects a distribution head, and this is also key component of the present invention.This distribution head is cylindrical, by top cover, upper cylinder, lower prop three parts, be socketed to form, the diameter of top cover slightly larger in diameter each charging aperture on distributing disc wherein, the diameter of upper cylinder is slightly less than the internal diameter of tubulation, the diameter of lower prop is slightly less than again cylinder, the real cylinder of upper cylinder, lower prop is hollow cylinder.Hollow tubulation is placed on outside distribution head, isometric with distribution head.
The external wall of upper prop has equally distributed three S type guiding gutters, and lower prop middle part and lower end are respectively connected with a distribution grid.On each distribution grid, be uniformly distributed four flow-guiding mouths.Flow-guiding mouth on upper and lower distribution grid becomes 45 degree to intersect, and in the middle of distribution head upper cover, opens charging aperture, and charging aperture bottom outwards has three flow-guiding mouths that are mutually 120 degree, and flow-guiding mouth is corresponding with three S type guiding gutters on upper cylinder.
In body, be longitudinally evenly distributed with nozzle for flow dismounting plate, nozzle for flow dismounting plate the right and left is alternately distributed.The area of each nozzle for flow dismounting plate is 1/2 to 2/3 of the interior sectional area of tubulation.
Body lower end is connected with centrum, and centrum is positioned at lower cover.
When liquid to be concentrated enters after the charging aperture on distribution head top cover, descending along the S type guiding gutter of upper cylinder.Because upper cylinder is real cylinder, outer wall is close to tubulation inwall, and lower flowing liquid can only be descending along tubulation inwall film forming, thereby reaches the first substandard cloth film.If have a small amount of liquid along inner tubal wall with interior lower, can drip on first distribution grid.Complete herein the second substandard cloth film.Same liquid that could not film forming at first distribution grid place completes cloth film for the third time on the 3rd distribution grid.By three substandard cloth films, just greatly having improved descending liquid becomes film uniformity.Nozzle for flow dismounting plate is alternately distributed along tubulation the right and left, and the heating steam that makes to enter falling film evaporation device is descending by the descending S of the becoming type of straight line split flow, has extended the arrhea time of steam between vaporising device tubulation and the time of contact of tubulation outer wall, has improved efficiency of utilization.
Research shows, adopts this falling film evaporation device, can improve the thermal efficiency more than 10%, enhances productivity more than 15%.
