Abstract
The utility model relates to a distribution device for a glass film evaporator, which is positioned above an evaporation surface, and is an annular and horizontally-arranged glass pipeline; the annular diameter of the distribution device is slightly smaller than the round diameter of the evaporation surface; the bottom of the pipeline is uniformly distributed with a plurality of discharge needle holes, commonly a certain included angle is formed between the axis and the evaporation surface, the preferred included angle is larger than 30 degrees but smaller than 60 degrees, and the best included angle is 45 degrees. The distribution device is further provided with a feeding neck part which is integrated with the glass pipeline; the feed liquor enters the glass pipeline of the distribution device, is pressurized, then isotonically ejected from the discharge needle holes in a certain angled needle shape, and uniformly sprayed on the evaporation surface, and flows automatically to form the film, thus forming the film with the uniform thickness on the evaporation surface when roller balls are rolled and calendered at certain rotating speed. The evaporation efficiency of the evaporator can be greatly improved with the film and be never influenced by the rotating speed; and due to no generation of splashing, the separation efficiency is high.
Description
Technical field
The utility model relates to a kind of chemical apparatuses equipment, refers in particular to a kind of thin film evaporator and distribution device thereof.
Background technology
The glass film evaporimeter is when charging, and cloth generally flows freely into, and the roller rest pearl rolls and takes feed liquid to evaporating surface, forms film.But film thickness is subjected to the influence of factors such as viscosity bigger, and when viscosity ratio was big, the uneven film thickness of formation was even, when the feed liquid viscosity hour, flowing velocity is very fast, blank parts can appear in the top of heating surface, influences evaporation efficiency.Also useful centrifugal distribution plate, but its shortcoming is after stirring acceleration, forms feed liquid and splashes, thereby influence vacuum evaporation efficient and carry generation secretly.
The utility model content
The technical problems to be solved in the utility model is the defective that overcomes existing cloth technology, provides a kind of cloth to be evenly distributed, and makes the distribution device of the glass film evaporimeter that evaporation efficiency improves greatly.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The distribution device of glass film evaporimeter is positioned at above the evaporating surface, and it is the glass pipe of annular, horizontal, and the diameter of annular is slightly less than the diameter of evaporating surface circle, uniform several discharging pin holes in the bottom of described pipeline.
Preferred glass pipe is a glass round tube, and distribution device also is provided with the neck of charging, and described neck and glass pipe are one-body molded.About the discharging pin hole, for discharging convenient, its axis generally should with evaporating surface α in a certain angle, described angle α is greater than 0 °, but less than 90 °; Preferred angle α is greater than 30 °, but less than 60 °, best angle α is 45 °.
Feed liquid enters in the glass pipe of distribution device through neck, through pressurization, feed liquid will be via discharging pin hole and the isobaric ejection of needle-like at an angle, and evenly being sprayed onto also flows automatically on the evaporating surface forms film, when the roller pearl rolls calendering with certain rotating speed, promptly on evaporating surface, form the uniform film of thickness.This film greatly improves evaporator evaporation efficient, and it is not influenced by any of rotating speed, because of the nothing generation of splashing, separative efficiency height.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the cross-sectional view of the distribution device of the utility model glass film evaporimeter;
Fig. 2 is the A portion enlarged drawing of the utility model Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the distribution device of glass film evaporimeter is positioned at above the evaporating surface 4, and it is the glass round tube 2 of annular, horizontal, and the diameter of annular is slightly less than the diameter of evaporating surface circle, uniform several discharging pin holes 3 in the bottom of pipeline 2; Distribution device also is provided with the neck 1 of charging, and neck 1 is one-body molded with glass round tube 2; The axis of discharging pin hole 3 and evaporating surface 4 α in a certain angle, preferred angle α are greater than 30 °, but less than 60 °, best angle α is 45 °.
Feed liquid enters in the glass round tube 2 of distribution device through neck 1, through pressurization, feed liquid will be via discharging pin hole 3 and the isobaric ejection of needle-like at an angle, evenly be sprayed onto on the evaporating surface 4 and gravity flow formation film, when roller pearl 5 rolls calendering with certain rotating speed, promptly on evaporating surface 4, form the uniform film of thickness.This film greatly improves evaporator evaporation efficient, and it is not influenced by any of rotating speed, because of the nothing generation of splashing, separative efficiency height.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
