Description

Technical Field

[0001] This utility model relates to the technical field of liquid distribution devices, specifically a distribution box and a liquid distributor. Background Technology

[0002] In the petrochemical industry, the basic function of tower equipment is to provide sufficient contact between the gas and liquid phases, enabling rapid and efficient mass and heat transfer processes. During this process, the tower internals provide the contact sites for mass and heat transfer between the gas and liquid phases. The tower internals determine the levels of some key technical and economic indicators, such as the yield of chemical products and their energy consumption.

[0003] As a type of tower internal, the function of a liquid distributor is to uniformly distribute liquid. Currently existing conventional distributors, such as trough-type liquid distributors, all involve the liquid first entering the primary trough, then being proportionally distributed to various secondary troughs, and finally flowing out through the liquid guide pipe. The problems with conventional distributors are: 1. The spray points are sparsely distributed, and the liquid cannot be evenly distributed on the packing layer, resulting in excessive or insufficient liquid in local areas. This uneven distribution will reduce mass transfer efficiency and may lead to the scale-up effect of the packed tower; 2. Under small liquid volume conditions, the operation flexibility is often small, and it is difficult to adapt to flow fluctuations.

[0004] Patent application number 202411528508.9 discloses a small-volume three-stage distributor, including several primary main tanks, several secondary branch tanks, and several distribution boxes. The primary main tanks are located below the secondary branch tanks, and each secondary branch tank has several evenly spaced distribution boxes at its bottom. Each distribution box has several spray holes at its bottom. Each secondary branch tank has a connecting pipe corresponding to one of the distribution boxes above it, and the lower end of the connecting pipe is connected to the corresponding distribution box. Each distribution box has several spray holes at its bottom. While the distribution box in patent application number 202411528508.9 can increase the number of spray points and improve operational flexibility, it has the following drawbacks: 1. The spray holes on the distribution box are prone to clogging; 2. The distribution box does not have a flow rate self-adaptive function. When the flow rate is high, the liquid will overflow from the top of the distribution box, and the spray holes will not be able to achieve uniform distribution. Utility Model Content

[0005] The main purpose of this invention is to provide a distribution box and liquid distributor to solve the problems of easy clogging of the distribution box and liquid overflow from the top of the distribution box when the flow rate is large in the prior art.

[0006] To achieve the above objectives, this utility model provides a distribution box, including a liquid collection box with an open top, a plurality of vertically arranged strip-shaped liquid outlets evenly distributed on the side of the liquid collection box, and a liquid guide plate fixedly connected to the bottom of the liquid collection box at a position opposite to the liquid outlet.

[0007] Furthermore, the outlet is V-shaped with a larger opening at the top and a smaller opening at the bottom.

[0008] Furthermore, the collection box is a square box with four outlets located at the four corners of the collection box.

[0009] Furthermore, a portion of the top of the liquid guide plate is fixedly connected to the liquid collection box, while the other portion extends to the outside of the liquid collection box.

[0010] Furthermore, the liquid guide plate is shaped like a right trapezoid, with the shorter waist of the right trapezoid fixedly connected to the liquid collection box, and the upper base of the right trapezoid located inside the lower base.

[0011] This utility model also provides a liquid distributor, including a primary tank, a secondary tank and a liquid guide pipe arranged sequentially along the liquid flow direction, and the aforementioned distribution box; the bottom of the liquid guide pipe is fixedly connected to the liquid collection box via a connecting frame.

[0012] Furthermore, the connecting frame includes two L-shaped frames, the top of which is fixedly connected to the liquid guide tube, and the bottom of which is fixedly connected to the liquid collection box by a bolt and nut assembly.

[0013] This invention, by setting up a liquid collection box, a liquid guide plate, and a vertically arranged strip-shaped liquid outlet, can increase the number of spray points, make the spraying more uniform, and increase the operational flexibility. Moreover, the vertical strip-shaped liquid outlet is less prone to clogging than the spray hole.

[0014] This invention features a V-shaped outlet, which allows for faster drainage when the flow rate is high and the liquid level in the collection box is high. This provides a flow rate self-adaptive function, preventing material accumulation in the collection box even with a high flow rate, thus avoiding liquid overflow from the top of the distribution box. Furthermore, the V-shaped outlet is less prone to clogging.

[0015] This invention, through the design of a liquid guiding plate, actively guides the flow of liquid, avoiding localized liquid accumulation or deviation, and overcomes the limitations of traditional gravity-fed flow. Attached Figure Description

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example 1 like Figures 1 to 3 As shown, a distribution box includes a liquid collection box 1 with an opening at the top. The liquid collection box 1 is a square box. Four vertically arranged strip-shaped liquid outlets 2 are evenly distributed on the side of the liquid collection box 1. The four liquid outlets 2 are located at the four corners of the liquid collection box 1. A liquid guide plate 3 is fixedly connected to the bottom of the liquid collection box 1 at the position opposite to the liquid outlets 2.

[0020] The shape of the liquid outlet 2 is a V-shape with a large opening at the top and a small opening at the bottom.

[0021] The top part of the liquid guide plate 3 is fixedly connected to the liquid collection box 1, and the other part extends to the outside of the liquid collection box 1.

[0022] The liquid guide plate 3 is in the shape of a right trapezoid. The shorter waist of the right trapezoid is fixedly connected to the liquid collection box 1, and the upper base of the right trapezoid is located inside the lower base.

[0023] After the liquid enters the collection box 1, it flows to the four outlets 2, and then flows from the outlets 2 to the guide plate 3, and finally flows out from the bottom end of the guide plate 3, thus distributing the liquid.

[0024] Example 2 like Figure 4 and Figure 5 As shown, a distributor, specifically a tank-type liquid distributor, includes a primary tank 4, a secondary tank 5, and a liquid guide pipe 6 arranged sequentially along the liquid flow direction, and also includes the distribution box in Embodiment 1; the bottom of the liquid guide pipe 6 is fixedly connected to the liquid collection box 1 through a connecting frame.

[0025] like Figure 3 As shown, the connecting frame includes two L-shaped frames 7. The top of the L-shaped frame 7 is fixedly connected to the liquid guide tube 6, and the bottom is fixedly connected to the liquid collection box 1 through the bolt and nut assembly 8.

[0026] In a conventional distributor, each liquid guide tube 6 is a spray point. In this embodiment, the distribution box is connected to the liquid guide tube 6, and each liquid guide plate 3 on the distribution box is a spray point, thereby increasing the number of spray points to 4 times the original number. This results in a smaller distance between adjacent spray points, more uniform spraying, and increased operational flexibility.

[0027] The above embodiments, by setting up a liquid collection box, a liquid guide plate, and a vertically arranged strip-shaped liquid outlet, can increase the number of rinsing points, make the spraying more uniform, and increase the operational flexibility. Moreover, the vertical strip-shaped liquid outlet is less prone to clogging than the spray hole.

[0028] The above embodiment sets the outlet in a V shape, so that when the flow rate is large and the liquid level in the collection box is high, the discharge speed of the outlet is faster; thus, it has a flow rate adaptive function. Even if the flow rate is large, the liquid collection box is not easy to accumulate, so there will be no problem of liquid overflowing from the top of the distribution box; and the V-shaped outlet is also less likely to be blocked.

[0029] The above embodiments, through the design of the liquid guiding plate, actively guide the liquid flow direction, avoid local liquid accumulation or deviation, and overcome the limitations of traditional gravity flow.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
