Description

Technical Field

[0001] The utility model belongs to the technical field of liquid distributors in separation towers, and in particular relates to a tube grid type liquid distributor in a tower. Background Art

[0002] Separation towers are primarily packed towers. Liquid entering the tower needs to be evenly distributed across its cross-section. The structure or device that performs this liquid distribution is called a liquid distributor. Liquid distributors play a vital role in various chemical production units, including chemical reactions, distillation, and absorption. The effectiveness of liquid distribution significantly impacts the effectiveness of chemical reactions, the efficiency of distillation and absorption towers, and directly determines the purity and yield of chemical products.

[0003] Traditional tubular liquid distributors spray the liquid to be treated into the tower in a dotted pattern through distribution pipes installed at the top or inside the tower. However, this dotted distribution method often leads to uneven liquid distribution within the tower, forming localized "dry" or "wet" zones, which in turn shortens the service life of the packing layer.

[0004] In order to solve the above problems, the industry continues to explore and optimize the design of liquid distributors, such as adjusting the layout of the distribution pipe, changing the aperture and shape of the liquid outlet, etc., but these methods are still difficult to fundamentally solve the problem of uneven liquid distribution.

[0005] Based on the above problems, the utility model proposes a tube grid type liquid distributor in a tower. Utility Model Content

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a tube grid type liquid distributor in a tower.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] A tube grid type liquid distributor in a tower, comprising:

[0009] connecting pipe;

[0010] A plurality of liquid distribution pipes are evenly and parallelly arranged on the connecting pipe, and each of the liquid distribution pipes is connected to the connecting pipe;

[0011] A plurality of liquid outlet holes are arranged at equal intervals on the liquid distribution pipe;

[0012] At least one grid bar is arranged below the liquid distribution pipe and directly facing the liquid outlet.

[0013] Furthermore, the liquid distribution pipe is provided with a plurality of rows of liquid outlet holes along its length direction, and grid bars are correspondingly provided below each row of liquid outlet holes.

[0014] Furthermore, each of the grating bars is provided with a plurality of liquid separation parts for guiding liquid splashing.

[0015] Furthermore, two ends of the grid bar are connected to two ends of the liquid distribution pipe through an adjustable component.

[0016] Furthermore, the shape of the grid bars is a flat strip or a cylindrical strip.

[0017] Furthermore, both ends of the connecting pipe are closed, and the middle portion of the liquid distribution pipe is connected to the connecting pipe.

[0018] Furthermore, the diameter of the connecting pipe is greater than or equal to the diameter of the liquid distribution pipe.

[0019] Furthermore, the shape of the liquid outlet is one of circular, elliptical, and V-shaped.

[0020] The utility model provides a tube grid type tower liquid distributor with the following beneficial effects:

[0021] Compared with the existing technology, the utility model improves the traditional tubular liquid distributor. A grid bar that can achieve secondary distribution of the liquid is set under the liquid distribution pipe. The grid bar can receive the liquid falling from the liquid outlet and make the liquid splash and disperse on it, thereby realizing secondary distribution of the liquid and transforming the point-like liquid distribution into surface-like liquid distribution to improve the uniformity of the liquid in the tower.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention and to be able to implement it, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] The utility model provides a tube grid type liquid distributor in a tower, specifically Figure 1-3 As shown, the tower comprises a connecting pipe 1, multiple liquid distribution pipes 2, multiple liquid outlet holes 3, and at least one grating 4. Multiple liquid distribution pipes 2 are evenly and parallelly arranged on the connecting pipe 1, and each liquid distribution pipe 2 is connected to the connecting pipe 1. Multiple liquid outlet holes 3 are evenly spaced on the liquid distribution pipe 2. At least one grating 4 is arranged below the liquid distribution pipe 2 and directly opposite the liquid outlet holes 3. The grating is configured to receive liquid falling from the liquid outlet holes and splash and disperse the liquid on it, thereby achieving secondary distribution of the liquid, transforming the point-like liquid distribution into a surface-like liquid distribution, and improving the uniformity of the liquid within the tower.

[0030] In this embodiment, in order to achieve uniform distribution of liquid at multiple levels, the liquid distribution pipe 2 is provided with multiple liquid discharge holes 3 along its length direction, and a grid bar 4 is correspondingly provided below each liquid discharge hole 3 .

[0031] Furthermore, the bars under different rows of liquid outlets may have different structures or layouts to meet the liquid distribution requirements of different areas.

[0032] In order to further enhance the splashing effect and distribution uniformity of the liquid, each grid bar 4 is provided with a plurality of liquid separation parts for guiding the splashing of the liquid.

[0033] As a preferred embodiment, the liquid separation member may be a protrusion for guiding liquid splashing;

[0034] As a preferred embodiment, the liquid separation member may be a groove for guiding liquid splashing;

[0035] As a preference, the liquid separation member may also be a perforation for guiding liquid splashing.

[0036] In order to facilitate adjustment of the distance between the grid bars and the liquid distribution pipe according to actual needs, thereby optimizing the splashing and distribution effects of the liquid, the two ends of the grid bars 4 are connected to the two ends of the liquid distribution pipe 2 through adjustable components.

[0037] As a preference, the adjustable component 5 is a manual telescopic rod or an electric telescopic rod.

[0038] Specifically, both ends of the connecting pipe 1 are closed, the middle of the liquid distribution pipe 2 is connected to the connecting pipe 1, and both ends of the liquid distribution pipe 2 are also sealed to facilitate liquid storage.

[0039] Specifically, the diameter of the connecting pipe 1 is greater than or equal to the diameter of the liquid distribution pipe 2 .

[0040] Specifically, the shape of the liquid outlet 3 is one of circular, elliptical, and V-shaped.

[0041] When the utility model is working, the liquid material enters the tubular liquid distributor from the liquid inlet of the connecting pipe, and the liquid level gradually rises to the position of the liquid outlet. The liquid sprays or drips onto the grid bars below through the liquid outlet. When the liquid is sprayed out from the liquid outlet and contacts the grid bars below, the liquid will splash and diffuse on the surface of the grid bars due to the blocking and dispersing effect of the grid bars. The splashed liquid continues to fall under the action of gravity, but due to the dispersing effect of the grid bars, the liquid no longer falls in a point form, but is distributed in a surface form. In this way, the liquid that may have been concentrated below the liquid outlet is effectively dispersed to a wider area, realizing the conversion from point distribution to surface distribution. Through the secondary distribution effect of the grid bars, the distribution of the liquid in the tower or container becomes more uniform. This helps to reduce the phenomenon of local over-wetting or over-drying and improve the overall treatment effect.

[0042] The above-described embodiments are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention fall within the protection scope of the present invention.
