Abstract
The utility model discloses a liquid collector of a rectification tower and the rectification tower. The liquid collector comprises a liquid collecting tank defined by an inner ring wall, an outer ring wall and a bottom plate, wherein a plurality of openings are formed in the bottom plate; and a plurality of first overflow holes are radially formed in the middle of the inner ring wall. According to the liquid collector, wall flow is collected in the liquid collecting tank and the collected wall flow flows out of the openings in the bottom plate; the collected wall flow flows out of the first overflow holes in the inner ring wall when the height of liquid in the liquid collecting tank reaches that of the first overflow holes; and the collected liquid is uniformly distributed to the whole rectification tower through the openings in the bottom plate and the first overflow holes in the inner ring wall, so that the rectifying efficiency is improved.
Description
Technical field
The utility model relates to a kind of parts of rectifying device of Chemical Manufacture, relates in particular to a kind of rectifying column liquid trap and rectifying column.
Background technology
Rectifying column produces wall stream easily when operation, generally by redistributor is installed in rectifying column wall stream is distributed in the whole tower uniformly, but when tower diameter hour, be not easy to install redistributor, for example diameter just is difficult for installing redistributor less than the rectifying column of 30mm, therefore, and at the bottom of the wall in the rectifying column fails to be convened for lack of a quorum and flows to tower along Ta Bi, so that the liquid backflow amount on the filler greatly reduces, thereby reduced the purity of overhead product.
At the bottom of preventing that the less rectifying column inwall of tower diameter stream from flowing to tower along the tower wall, usually can in tower, one circle baffle plate be installed as liquid trap every a determining deviation, by baffle plate wall stream is directed in the following condiment, thereby increases fluid flow on the filler.But present baffle plate liquid trap only is the up big and down small conically shaped structure of a circle, and it can only enough be directed to wall stream on the filler that is positioned at same orientation, is difficult to Jiang Biliu and is evenly distributed in the whole rectifying column, thereby has reduced the overall performance of rectifying column.
The utility model content
In view of this, the utility model provides a kind of rectifying column liquid trap, by the improvement to the structure of rectifying column liquid trap, existingly wall stream can not be evenly distributed to whole rectifying column and cause the low technical problem of rectifying column performance to solve.
The utility model solves the problems of the technologies described above by following technological means:
Rectifying column liquid trap of the present utility model comprises by internal ring wall, external annulus and base plate enclosing the collecting tank that forms, and is provided with some perforates on the described base plate, and the middle part of described internal ring wall has been disposed radially some the first spout holes.
Further, described internal ring wall and described external annulus are tapered, and the aperture, upper end of described internal ring wall is less than the aperture, lower end, and the aperture, upper end of described external annulus is greater than the aperture, lower end.
Further, the aperture of the perforate on the described base plate is less than the aperture of described the first spout hole.
Corresponding to above-mentioned rectifying column liquid trap, the utility model also provides a kind of rectifying column, comprises tower body, also comprises any one above-mentioned rectifying column liquid trap, and described rectifying column liquid trap is installed in the described tower body removably.
The beneficial effects of the utility model: rectifying column liquid trap of the present utility model, by wall stream is collected in the collecting tank, and the wall stream of collecting will be flowed out by the perforate on the base plate, liquid height in collecting tank reaches the height of the first spout hole, then flowed out by the first spout hole on the internal ring wall, reach the liquid of collecting and to be evenly distributed to whole rectifying column by the first spout hole on the perforate on the base plate and the internal ring wall, and then improved rectification efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of rectifying column liquid trap of the present utility model.
The specific embodiment
Below with reference to accompanying drawing the utility model is elaborated.
Referring to Fig. 1, be the structural representation of an embodiment of rectifying column liquid trap of the present utility model, during implementation, this liquid trap comprises by internal ring wall 1, external annulus 2 and base plate 3 and encloses the collecting tank 4 that forms.During implementation, in the present embodiment this internal ring wall 1 be the aperture, upper end less than the taper in aperture, lower end, and the middle part of this internal ring wall 1 is provided with the first spout hole 11; External annulus 2 is that the aperture, upper end is greater than the taper in aperture, lower end; Be provided with some perforates 31 on the base plate 3.
The rectifying column liquid trap of present embodiment, by wall stream is collected in the collecting tank 4, and the wall stream of collecting will be flowed out by the perforate 31 on the base plate 3, liquid height in collecting tank 4 reaches the height of the first spout hole 11, then flowed out by the first spout hole 11 on the internal ring wall 1, reach the liquid of collecting and to be evenly distributed to whole rectifying column by the first spout hole 11 on the perforate 31 on the base plate 3 and the internal ring wall 1, and then improved rectification efficiency.
Based on the rectifying column liquid trap of above-described embodiment, the utility model also provides a kind of rectifying column, comprises tower body, also comprises the rectifying column liquid trap of embodiment, and it is installed in the described tower body removably.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
