Abstract
The invention relates to a cloth device for a glass film evaporator. The cloth device is arranged on an evaporation surface and is an annular and horizontal glass pipeline, the diameter of the annular part is slightly less than the diameter of the circle of the evaporation surface, a plurality of discharging pin holes are uniformly distributed at the bottom of the pipeline, and a certain included angle is generally kept between the axis of the pipeline and the evaporation surface, the included angle is bigger than 30 degrees preferably and is smaller than 60 degrees, and the optimal included angle is 45 degrees. The cloth device is also provided with a feeding neck, the neck and the glass pipeline are integrated; feed liquid enters into the glass pipeline of the cloth device by virtue of the neck, forcing is carried out, the feed liquid is acicularly sprayed under constant pressure in certain angle by virtue of the discharging pin holes, is uniformly sprayed onto the evaporation surface and automatically flows into a thin film, and an uniform thin film is formed on the evaporation surface when roller beads roll and calendar at a certain rotating speed. The thin film can ensure the evaporation efficiency of an evaporator to be greatly improved, the evaporator can not be influenced by the rotating speed, and no splashing is caused, thus the separation efficiency is high.
Description
Technical field
The present invention relates to a kind of chemical apparatuses equipment, refer 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.
Summary of the invention
The technical problem to be solved in the present invention 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 invention 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 invention, and constitutes the part of specification, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the cross-sectional view of the distribution device of glass film evaporimeter of the present invention;
Fig. 2 is the A portion enlarged drawing of Fig. 1 of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Embodiment 1
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 the preferred embodiments of the present invention, be not limited to the present invention, although the present invention 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.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
