The second purpose of the utility model is to provide a tubular liquid distributor for packed tower to existing technical current situation, will set up side by side the liquid distribution pipe change into cross arrangement, wholly be "rice" style of calligraphy, the distribution covers than higher, and the cloth liquid is more even.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a tubular liquid distributor for packed tower, includes feed liquor pipe, liquid distribution groove and a plurality of liquid distribution pipe, the liquid distribution groove is the ring form cell body, feed liquor pipe and liquid distribution groove intercommunication, and the downside of every liquid distribution pipe all is equipped with quantity, the unanimous distribution hole in aperture, and adjacent distribution hole interval is the same, and the one end of whole liquid distribution pipe evenly sets up and the other end assembles arbitrary department on the liquid distribution groove axis along the interior circumference of liquid distribution groove, and whole liquid distribution pipe wholly is "rice" style of calligraphy, sets up liquid distribution pipe department and all is equipped with the overflow hole in the interior circumference of liquid distribution groove.
Furthermore, the convergence position of all the liquid distribution pipes is positioned below the central point of the liquid distribution groove, so that each liquid distribution pipe is inclined by 5-10 degrees.
Furthermore, the liquid distribution pipe is in a continuous wavy line shape,
further, the distribution holes are arranged on two sides of the wave crest or the wave trough of the liquid distribution pipe.
Further, the liquid inlet of the distribution hole is higher than the inner wall of the liquid distribution pipe.
The utility model has the advantages that:
1. compared with the prior art, the tubular liquid distributor for the packed tower changes the linear type of the liquid distribution groove into the annular type, prolongs the length of the liquid distribution groove, has larger distribution volume, changes the liquid distribution pipes arranged side by side into the crossed type, has a meter-shaped whole body, has higher distribution coverage ratio and more uniform liquid distribution;
2. the liquid inlet time and the liquid distribution speed of the front half part and the rear half part of the traditional liquid distribution pipe are different, so that the liquid distribution amount and the liquid distribution speed of the front half part are larger than those of the rear half part, and when the liquid distribution pipe is in an inclined state, the gravity potential energy makes up the liquid inlet time difference and the pressure difference, so that the liquid distribution amount and the liquid distribution speed of the front half part and the rear half part are balanced;
3. the liquid distribution pipe is in a continuous wavy line shape, so that the length of the pipeline is increased, and the pipeline has more distribution hole arrangement surfaces;
4. the distribution hole arrangement surfaces are designed on the two sides of the wave crest or the wave trough of the liquid distribution pipe, so that the sediment falls into the wave trough, thereby avoiding blocking the distribution holes and reducing the maintenance time of equipment;
5. the liquid inlet of the distribution holes is higher than the inner wall of the liquid distribution pipe, so that the distribution holes can block sediments, and the distribution holes are prevented from being blocked.

Detailed Description
Please refer to fig. 1, a tubular liquid distributor for a packed tower includes a liquid inlet pipe 4, a liquid distribution tank 1 and a plurality of liquid distribution pipes 2, the liquid distribution tank 1 is a circular ring-shaped tank body, the liquid inlet pipe 4 is communicated with the liquid distribution tank 1, the lower side of each liquid distribution pipe 2 is provided with distribution holes 5 with the same number and aperture, the distance between the adjacent distribution holes 5 is the same, one end of all the liquid distribution pipes 2 is uniformly arranged along the inner circumference of the liquid distribution tank 1, and the other end is converged to any position on the axis of the liquid distribution tank 1, the whole liquid distribution pipe 2 is in a shape like a Chinese character 'mi', and the positions of the inner circumference of the liquid distribution tank 2 where the liquid distribution pipes 2 are arranged are provided with overflow holes.
Specifically, the working process is as follows: the liquid phase is guided into the liquid distribution groove 1 through the liquid inlet pipe 4, is evenly distributed into all the liquid distribution pipes 2 through the overflow holes 3, and is distributed through the distribution holes 5.
Above-mentioned technical scheme changes liquid distribution groove 1 into the annular by the linear type, has prolonged the length of liquid distribution groove 1, makes it have bigger distribution volume, changes the liquid distribution pipe 2 that sets up side by side into alternately setting, wholly is "rice" style of calligraphy, and the distribution is covered than higher, and it is more even to distribute liquid. Because the liquid distribution groove 1 is annular, auxiliary equipment such as the liquid inlet pipe 4, the liquid level meter and the like can be installed at any position along the circumference of the liquid distribution groove, and the construction operation is quicker.
Referring to fig. 2, the convergence of all the liquid distribution pipes 2 is located below the central point of the liquid distribution tank 1, so that each liquid distribution pipe 2 is inclined by 5-10 °. Preferably, each liquid distribution conduit 2 is inclined at 6 °.
The first half of traditional liquid distribution pipe 2 is different with the feed liquor time, the pressure homogeneous phase of the latter half, makes its first half of cloth liquid measure, cloth liquid speed be greater than the latter half, and when liquid distribution pipe 2 was the tilt state, gravitational potential energy remedied feed liquor time difference and pressure differential to balanced first half and the first half of cloth liquid measure and cloth liquid speed of latter half.
Referring to fig. 3, the liquid distribution pipe 2 is in a continuous wavy line shape, so that the length of the liquid distribution pipe 2 is increased, and the liquid distribution pipe has more distribution hole arrangement surfaces.
Preferably, the distribution holes 5 are arranged on both sides of the wave crest or wave trough of the liquid distribution pipe 2. The distribution holes 5 are arranged on the two sides of the wave crest or the wave trough of the liquid distribution pipe, so that the sediment falls into the wave trough, the distribution holes 5 are prevented from being blocked, and the equipment maintenance time is shortened.
Preferably, the liquid inlet of the distribution holes 5 is higher than the inner wall of the liquid distribution pipe 2, so that the distribution holes 5 themselves can block the deposits, thereby avoiding clogging of the distribution holes 5.
Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
