Abstract
The utility model provides a film evaporator, relates to evaporation equipment, and it includes the barrel and sets up feed inlet, the discharge gate at the barrel both ends, last steam inlet and the steam outlet of being equipped with of cylinder side wall, feed inlet below is equipped with the dispersion impeller, and support rib plate fixes on the barrel inner wall for the dispersion impeller, and the dispersion impeller below is equipped with distribution dish, well distribution dish and distribution dish down in proper order, goes up distribution dish, well distribution dish and is equipped with through -hole, well through -hole down in the quotation of distribution dish and through -hole down, and go up through -hole, well through -hole and diameter of hole is different down, and relative stagger, is equipped with the tube sheet below the lower distribution dish, the interior expanded joint heating pipe of tube sheet. This device adopts that the through -hole is not of uniform size, wrongly mutually go up the position in, distribution dish down, and it is more even to make the liquid material distribute before the film forming, and film effects is better, and the effect is more ideal during the evaporation, the conical head that the barrel low head adopted is difficult for causing the discharge gate to block up, consequently can obtain more high -quality material, brings huge income for the evaporation cause.
Description
technical field:
The utility model relates to evaporation equipment, is specifically related to a kind of thin film evaporator.
background technology:
At present, in industries such as medicine, food processing, chemical industry, metallurgy, the demand of evaporation equipment is constantly expanded, also more and more higher to the requirement of evaporation effect, existing great majority are all at use thin film evaporator, fouling, blocking and existing thin film evaporator is large to the resistance of fluid, easily causes dispersion impeller and distributing disc fouling in evaporimeter, the phenomenon of blocking occur, once will cause liquid material skewness, film-formation result is not good, and evaporation effect also reduces thereupon greatly.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and a kind of thin film evaporator is provided, its structure is simple, it is easy for installation to process, employing hole size differs, three distributing discs of lead to the hole site staggered relative, liquid material can be made to be evenly distributed, better effects if during liquid material film forming, and then reach more preferably evaporation effect, be easy to large-scale promotion application.
In order to solve the problem existing for background technology, the utility model adopts following technical scheme: comprise cylindrical shell and the charging aperture, the discharging opening that are arranged on cylindrical shell both ends, cylinder lateral wall is provided with steam inlet and steam (vapor) outlet, the lower end of charging aperture extend in cylindrical shell, dispersion impeller is provided with below charging aperture, dispersion impeller bearing rib is fixed on cylinder inboard wall, the upper distributing disc be welded on bearing rib is provided with below dispersion impeller, middle distributing disc and lower distributing disc is provided with successively below upper distributing disc, upper distributing disc, middle distributing disc is fixedly connected with by distance sink tube with lower distributing disc, upper distributing disc, the card of middle distributing disc and lower distributing disc is provided with through hole, middle through hole and lower through-hole, upper through hole, middle through hole is different with lower through-hole diameter, and relative misalignment arrangement, tube sheet is provided with below lower distributing disc, tube sheet support member is fixed on cylindrical shell, expanded joint heating tube in tube sheet.
The card of described dispersion impeller there is multiple through hole.
Through-hole alignment heating tube on described lower distributing disc.
What the low head of described cylindrical shell adopted is conical head.
The utility model is reasonable in design, structure is simple, easy to operate, three, the upper, middle and lower distributing disc adopted, can not produce and affect the not good phenomenon of liquid material film-formation result because of through hole blocking, hole size in three distributing disc cards differs, position relative misalignment, can make like this that liquid material distributes before film forming evenly, and then reach more preferably evaporation effect; The conical head that cylindrical shell low head adopts, such head design can not cause discharging opening to block.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Fig. 2 is distributing disc through hole relative position schematic diagram.
detailed description of the invention:
With reference to each figure, the utility model specifically adopts following embodiment: comprise cylindrical shell 11 and the charging aperture 1, the discharging opening 13 that are arranged on cylindrical shell 11 both ends, cylindrical shell 11 sidewall is provided with steam inlet 5 and steam (vapor) outlet 12, the lower end of charging aperture 1 extend in cylindrical shell 11, dispersion impeller 2 is provided with below charging aperture 1, dispersion impeller 2 bearing rib is fixed on cylindrical shell 11 inwall, the upper distributing disc 8 be welded on bearing rib is provided with below dispersion impeller 2, middle distributing disc 9 and lower distributing disc 10 is provided with successively below upper distributing disc 8, upper distributing disc 8, middle distributing disc 9 is fixedly connected with by distance sink tube 3 with lower distributing disc 10, upper distributing disc 8, the card of middle distributing disc 9 and lower distributing disc 10 is provided with through hole 16, middle through hole 15 and lower through-hole 14, upper through hole 16, middle through hole 15 is different with lower through-hole 14 diameter, and relative misalignment arrangement, tube sheet 4 is provided with below lower distributing disc 10, tube sheet 4 support member is fixed on cylindrical shell 11, expanded joint heating tube 6 in tube sheet 4.The card of described dispersion impeller 2 there is multiple through hole.Through hole 14 on described lower distributing disc 10 aims at heating tube 6.What the low head of described cylindrical shell 11 adopted is conical head 7.
Liquid material enters from the charging aperture 1 of cylindrical shell 11, successively through dispersion impeller 2, upper distributing disc 8, middle distributing disc 9 and lower distributing disc 10, heating tube 6 is distributed to fast after liquid material is evenly distributed by dispersion impeller 2 and three distributing discs, and form film-form at the tube wall of heating tube 6, flow downward under gravity, when steam enters from steam inlet 5, can contact with the liquid material of film forming, and the moisture evaporated in liquid material, steam after utilization is discharged from steam (vapor) outlet 12, liquid material after evaporation is along sliding to conical head 7 under barrel, then be directly slipped to discharging opening 13 along the cone wall of conical head 7 to discharge, such cone wall can not cause the accumulation of discharging opening 13, discharge high-quality material, complete evaporation process.
This apparatus structure is simple, process easy for installation, have employed distributing disc 8, middle distributing disc 9 and lower distributing disc 10, and the hole size in three distributing disc cards differs, is staggeredly located, liquid material not only can not be caused to block the phenomenon of through hole, but also distribute before liquid material film forming can be made evenly, and then liquid material film-formation result is good, more preferably evaporation effect will be reached, for evaporation cause brings huge income.
