Abstract
Description
Technical Field
[0001] This utility model relates to the field of distributor technology, specifically a two-stage slotted distributor. Background Technology
[0002] Distributors are important equipment in chemical, petroleum, and environmental protection fields. They are mainly used to uniformly distribute fluids (liquids or gases) into a specific space or equipment to ensure the efficiency and stability of the process.
[0003] The trough distributor mainly consists of a main trough, a secondary trough, a liquid distribution structure, and a support structure. The main trough receives upstream liquid and plays a preliminary role in collection and distribution. It is usually connected to the equipment feed pipe. The secondary trough mainly receives the liquid distributed by the main trough and further distributes it evenly to the packing layer or bed. The liquid distribution structure includes liquid distribution holes, weir plates, or flow guiding devices at the bottom of the trough. Liquid drips through the liquid distribution holes or overflows through the weir plates to form a liquid flow. The support structure is used to fix the trough distributor.
[0004] However, existing tank-type distributors mainly distribute liquid through the distribution holes at the bottom of the tank after receiving the liquid. However, the distribution holes at the bottom of the distributor are not evenly distributed, and their distribution is mainly at the bottom of the tank, which results in uneven liquid distribution.
[0005] To address the problems mentioned above, those skilled in the art have proposed a two-stage slotted distributor. Utility Model Content
[0006] The purpose of this invention is to provide a two-stage slotted distributor to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A two-stage trough-type distributor includes a base plate on which several elongated liquid collection troughs are installed. The length of each liquid collection trough gradually decreases from the middle to both sides. A connecting cavity is formed inside each liquid collection trough, and several connecting holes are formed on the side walls of the liquid collection troughs. A liquid collection chamber is formed at the bottom of the base plate, and several liquid distribution holes are formed between the liquid collection chamber and the connecting cavity, and are arranged at intervals along the liquid collection troughs. Several air risers penetrating the bottom of the base plate are installed inside the connecting cavity. A conveying pipe is connected to the bottom of the base plate, and a disc is installed at the bottom of the conveying pipe.
[0009] As a further embodiment of this utility model: a uniform distribution cavity is provided in the disk body, a uniform distribution platform is installed at the bottom of the uniform distribution cavity, a plurality of flow guide grooves are provided on the surface of the uniform distribution platform, the plurality of flow guide grooves are distributed in a ring at intervals, and the ends of the plurality of flow guide grooves near the axis of the uniform distribution platform are in a connected state, and a plurality of flow guide holes are provided in the flow guide grooves at intervals and extending out of the bottom of the disk body.
[0010] As a further improvement of this utility model, the surface of the guide groove is set as an inclined surface.
[0011] As a further improvement of this utility model: a cone is installed in the middle of the uniform distribution platform, and the cone extends into the conveying pipe.
[0012] As a further improvement of this utility model: several mounting brackets are installed inside the liquid collection tank, and a liquid baffle is installed on the top of the mounting bracket, the liquid baffle being V-shaped.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model installs the device inside a packed tower, and then collects the liquid above through the bottom plate. When the liquid height above the bottom plate is higher than the connecting hole, the liquid above the bottom plate will enter the connecting cavity of the liquid collection tank through the connecting hole, and then be guided into the liquid collection cavity through the liquid distribution hole at the bottom of the liquid collection tank. Then, it is transported to the top center of the plate through the conveying pipe. The liquid transported by the conveying pipe can be separated by the cone at the top of the evenly distributed plate, so that the liquid enters several guide grooves on the evenly distributed platform, and is discharged through the guide holes at the bottom of the guide grooves. Since the several guide holes at the bottom of the plate are evenly distributed, the dripping liquid can be evenly distributed. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] Please see Figures 1-4 A two-stage trough-type distributor includes a base plate 1, on which a plurality of spaced liquid collection troughs 2 are installed. The liquid collection troughs 2 are elongated and their length gradually decreases from the middle to both sides. A connecting cavity 3 is opened in the liquid collection trough 2, and a plurality of connecting holes 5 are opened on the side wall of the liquid collection trough 2. A liquid collection chamber 7 is opened at the bottom of the base plate 1. A liquid distribution hole 4 is opened between the liquid collection chamber 7 and the connecting cavity 3. A plurality of liquid distribution holes 4 are provided and are spaced along the liquid collection trough 2. A plurality of air riser pipes 6 penetrating the bottom of the base plate 1 are installed inside the connecting cavity 3. A conveying pipe 10 is connected to the bottom of the base plate 1, and a disc body 11 is installed at the bottom of the conveying pipe 10.
[0021] In one embodiment, the disk body 11 has a uniform distribution cavity 12, and a uniform distribution platform 13 is installed at the bottom of the uniform distribution cavity 12. The surface of the uniform distribution platform 13 has a plurality of flow guide grooves 14, which are distributed in a ring at intervals. The ends of the flow guide grooves 14 near the axis of the uniform distribution platform 13 are in a connected state. The flow guide grooves 14 are provided with a plurality of flow guide holes 15 that are distributed at intervals and extend out of the bottom of the disk body 11.
[0022] The uniform distribution platform 13 is frustum-shaped, and several guide channels 14 are arranged on the outer wall of the uniform distribution platform 13. The guide channels 14 are channels with a certain depth to facilitate the flow of liquid in the guide channels 14. At the same time, several guide holes 15 in the guide channels 14 are arranged vertically and penetrate the bottom of the disk body 11.
[0023] The liquid entering the disc 11 from the delivery pipe 10 will diffuse from the center of the distribution platform 13 to the surrounding guide channels 14, allowing the liquid to flow to different guide channels 14.
[0024] In one embodiment, the surface of the guide groove 14 is sloped.
[0025] The inclined guide channel 14 allows the liquid entering the guide channel 14 to flow along the surface of the guide channel 14, thereby reducing the resistance to liquid flow.
[0026] In one embodiment, a cone 16 is installed in the middle of the uniform distribution platform 13, and the cone 16 extends into the conveying pipe 10.
[0027] By setting the cone 16, the liquid transported in the delivery pipe 10 can automatically radiate outwards when it enters the disc 11.
[0028] In one embodiment, a plurality of mounting brackets 8 are installed in the liquid collection tank 2, and a liquid baffle 9 is installed on the top of the mounting bracket 8. The liquid baffle 9 is V-shaped.
[0029] The liquid baffle 9 can shield the top of the liquid collection tank 2 to prevent liquid from directly entering the connecting cavity 3 and the riser pipe 6. The V-shaped liquid baffle 9 can collect the dripping liquid in a concentrated manner, reduce the occurrence of liquid splashing, and facilitate the dispersion of the gas discharged from the riser pipe 6 to both sides, making it easier for the gas and liquid to mix.
[0030] The working principle of this utility model is as follows: by installing this device in the packed tower, the liquid above is collected through the bottom plate 1. When the liquid height above the bottom plate 1 is higher than the connecting hole 5, the liquid above the bottom plate 1 will enter the connecting cavity 3 of the liquid collection tank 2 through the connecting hole 5, and then be introduced into the liquid collection cavity 7 through the liquid distribution hole 4 at the bottom of the liquid collection tank 2. Then, it is transported to the top center of the plate body 11 through the conveying pipe 10. The liquid transported by the conveying pipe 10 can be separated by the cone 16 at the top of the evenly distributed plate, so that the liquid enters into several guide grooves 14 on the evenly distributed platform 13, and is discharged through the guide holes 15 at the bottom of the guide grooves 14. Since the several guide holes 15 at the bottom of the plate body 11 are evenly distributed, the dripping liquid can be evenly distributed.
