Description
Technical Field
The utility model relates to the technical field of chemical equipment, in particular to a liquid feeding distribution pipe for a packed tower.
Background
The tower equipment is one of the most important equipment in the production of chemical industry, petrochemical industry, oil refining and the like, wherein the packed tower takes the packing as a basic component for gas-liquid contact and mass transfer, has the advantages of pressure reduction, large flux, high efficiency and the like, and is widely applied. In the operation of a packed column, the initial distribution of liquid has the greatest effect on the performance of the packed column, so the structural design of the liquid feed distribution tubes is of paramount importance. The liquid feed distribution pipes of the packed tower commonly used in industry are various in form, and for towers with larger diameters, a calandria liquid feed pipe is most commonly used; when the diameter of the packed tower is smaller, workers cannot enter the packed tower, and the calandria liquid feeding pipe is difficult to manufacture and install. At present, a liquid feeding pipe with a straight insertion type or an end part made into a bent pipe type is commonly used, and the two structures can lead to uneven liquid spraying and low packing surface contact efficiency, so that the mass transfer efficiency of a packing tower is influenced.
For the above reasons, there is a need for an improvement in the structure of the liquid feed distribution tube of a small diameter packed column.
Disclosure of Invention
The utility model aims to provide a liquid feeding distribution pipe suitable for a packed tower, and solves the technical problems that a calandria liquid feeding pipe is difficult to manufacture and install when the diameter of the packed tower is smaller and workers cannot enter in the background art.
The utility model is mainly solved by the following technical scheme:
the liquid feed distribution pipe for the packed tower is characterized by comprising a liquid feed pipe assembly which is fixed on the side surface of the packed tower and horizontally penetrates into a feed inlet of the packed tower; the liquid inlet pipe assembly comprises a liquid inlet pipe, the end part of the liquid inlet pipe is connected with a bell mouth through a 90-degree elbow, a sealing plate is welded at the end part of the bell mouth, and small holes are formed in the sealing plate.
Preferably, a horizontal sleeve is welded at the side feed port of the packed tower, and the aperture of the horizontal sleeve meets the requirement that the liquid feed pipe assembly can enter the packed tower.
Preferably, the liquid feed pipe assembly extends through a horizontal sleeve into the center of the packed column and is secured to the connection flange cover by a sleeve flange.
Preferably, the diameter of the central through hole of the flange cover for connection is 1.5-2 mm larger than the outer diameter of the liquid feeding pipe.
Preferably, the flare cone angle is 60 °.
Preferably, the sealing plate is fully distributed with uniformly distributed small holes.
When the utility model is used for feeding, liquid enters through the feeding pipe and is uniformly sprayed to the filler through the small holes on the sealing plate at the bottom of the bell mouth, so that the effect of uniform distribution is achieved.
When the liquid feeding distribution pipe needs to be disassembled in the equipment maintenance process, the bolts and nuts are loosened, and the liquid feeding pipe assembly is integrally pulled out from the side face; during installation, the liquid feed pipe assembly is directly stretched into the center of the packing tower from the outside of the equipment through the horizontal sleeve, and bolts and nuts are fastened, so that the installation is convenient and quick.
The size and the number of the small holes on the sealing plate are calculated and determined according to the liquid flow.
The beneficial technical effects of the utility model are as follows:
compared with the prior art, the liquid feeding distribution pipe of the packing tower is reasonable in design, simple in structure and convenient to operate, is particularly suitable for disassembling and assembling the liquid feeding distribution pipe outside conveniently when the diameter of the packing tower is smaller and workers cannot enter the packing tower, and obviously saves time and improves working efficiency obviously.
Drawings
Fig. 1 is a schematic structural view of a liquid feed distribution pipe for a packed column according to an embodiment of the present utility model.
In the figure, 1 is a horizontal sleeve, 2 is a sleeve flange, 3 is a flange cover for connection, 4 is a liquid feeding pipe, 5 is a 90-degree elbow, 6 is a bell mouth, and 7 is a sealing plate.
Description of the embodiments
The utility model will be further described with reference to the drawings and the detailed description.
Examples
A liquid feed distribution pipe structure for a packed tower is shown in figure 1. The device mainly comprises a horizontal sleeve 1, a sleeve flange 2, a flange cover 3 for connection, a liquid feeding pipe 4, a 90-degree elbow 5, a horn mouth 6 and a sealing plate 7.
The end part of the liquid feeding pipe is connected with the 90-degree elbow and the bell mouth, and a sealing plate is welded at the end part of the bell mouth. And (3) opening holes in the side feed inlet positions of the packed tower, and welding a horizontal sleeve, wherein the hole diameter can enable the liquid feed pipe assembly to enter the tower. The liquid feeding pipe extends into the center of the packed tower through the horizontal sleeve and is fixed with the sleeve flange through the flange cover for connection. The diameter of the central through hole of the flange cover for connection is 1.5-2 mm larger than the outer diameter of the liquid feeding pipe; the cone angle of the horn mouth is 60 degrees; the seal plate is provided with a small Kong Manbu. During feeding, liquid enters through the feeding pipe and is uniformly sprayed to the filler through the small holes on the sealing plate at the bottom of the bell mouth, so that the effect of uniform distribution is achieved.
