Description
Technical Field
[0001] This utility model relates to the field of desulfurization tower technology, specifically to a desulfurization tower gas-liquid distributor based on baffle plate enhancement. Background Technology
[0002] A desulfurization tower is a tower-type device used to treat industrial waste gas for desulfurization. Initially, desulfurization towers were most widely used, constructed primarily of granite. Utilizing the principle of water film desulfurization and dust removal, they are also known as granite water film desulfurization and dust collectors or marble water film desulfurization and dust collectors. A demister is installed at the top of the desulfurization tower. Through the collision action of the demister's baffles, the dust, water droplets, and solid particles carried by the flue gas are captured and separated by the demister. A gas-liquid distributor is a gas-liquid distribution device installed at the top of a packed tower. The function of the gas-liquid distributor is to uniformly distribute or redistribute the liquid at the top of the packing or at a certain height.
[0003] In existing gas-liquid distributors, under normal gas-liquid flow rates, the liquid level is between the gas and liquid inlets. Gas enters the cavity through the upper opening and the circular orifice. Due to the sudden decrease in the flow cross-section, the gas velocity suddenly increases, creating a suction effect on the liquid. The liquid enters through two symmetrical tangential inlets at the bottom of the cavity. Through the suction effect of the gas, the liquid undergoes a spiral motion along the vertical axis inside, increasing the turbulence and mixing degree of the fluid. At the end of the cavity, the cross-section at the throat decreases, further increasing the gas-liquid flow velocity and creating a jet effect. Finally, it is ejected from the conical orifice, expanding the distribution area. However, the relatively small volume inside the cavity makes it difficult for all the suctioned liquid to enter the jet pipe.
[0004] The aforementioned gas-liquid distributor has an increased distribution time due to the difficulty of the liquid entering the jet pipe during the movement process, which reduces the effectiveness of the device. Utility Model Content
[0005] This invention proposes a desulfurization tower gas-liquid distributor based on baffle plate enhancement to solve the problem in the prior art that it is difficult for all liquid to enter the inside of the spray pipe.
[0006] The technical solution of this utility model is as follows: A gas-liquid distributor for a desulfurization tower based on baffle plate enhancement, including a connecting box, and further comprising:
[0007] The connecting frame is connected to the upper surface of the connecting box. A connecting housing is installed on the outer side of the connecting frame.

A blade is installed on the outer surface of the first transmission rod. A first bevel gear is installed on the outer end of the first transmission rod. The second transmission rod is rotatably connected to the connecting housing. A second bevel gear is installed on the end of the second transmission rod near the first bevel gear. The first bevel gear meshes with the second bevel gear. The transmission gear is sleeved on the end of the second transmission rod away from the first bevel gear. A movable plate is slidably connected inside the connecting housing. A rack is installed on the lower surface of the movable plate. The transmission gear meshes with the rack. The auxiliary frame is installed on the upper surface of the connecting housing. A movable rod is installed on the upper surface of the movable plate. The movable rod passes through the inside of the connecting housing. One end of the movable rod passing through the connecting housing enters the auxiliary frame. A buffer spring is installed on the upper surface of the movable plate. The movable rod passes through the inside of the buffer spring. The inclined plate is slidably connected to the auxiliary frame. The top end of the movable rod is installed on the lower surface of the inclined plate.
[0008] As a preferred embodiment of the desulfurization tower gas-liquid distributor based on baffle plate enhancement described in this utility model, in order to better transfer liquid, a liquid storage box is connected to the side of the auxiliary frame, and the lower surface of the liquid storage box is connected to the upper surface of the connecting frame.
[0009] As a preferred embodiment of the desulfurization tower gas-liquid distributor based on baffle plate enhancement described in this utility model, in order to accelerate the liquid transfer speed, the lower surface of the auxiliary frame is connected to a drain pipe, the inside of the connecting box is connected to a distribution pipe, and the bottom end of the drain pipe is connected to the distribution pipe located in the middle.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0023] like Figures 1-4As shown, this embodiment proposes a desulfurization tower gas-liquid distributor based on baffle plate enhancement, including a connecting box 1, a connecting frame 2, a connecting box 3, a first transmission rod 4, a blade 5, a first bevel gear 6, a second transmission rod 7, a second bevel gear 8, a transmission gear 9, a moving plate 10, a rack 11, an auxiliary frame 12, a moving rod 13, a buffer spring 14, and an inclined plate 15;
[0024] like Figures 2-4 As shown, the connecting frame 2 is connected to the upper surface of the connecting box 1. A connecting box 3 is installed on the outer side of the connecting frame 2. The first transmission rod 4 is rotatably connected inside the connecting box 3, and the inner end of the first transmission rod 4 is rotatably connected inside the connecting frame 2. A blade 5 is installed on the outer surface of the first transmission rod 4. The blade 5 is driven by the liquid to rotate the first transmission rod 4. The rotation of the first transmission rod 4 drives the first bevel gear 6 to rotate. The rotation of the first bevel gear 6 meshes with the second bevel gear 8 to rotate. The rotation of the second bevel gear 8 drives the second transmission rod 7 to rotate. Through the transmission gear 9, the rack 11 is lifted upward. It should be noted that the second transmission rod 7 is fixed to the top of the connecting box 3, so the rack 11 has enough space to move. The outer end of the first transmission rod 4 is equipped with the first bevel gear 6. The second transmission rod 7 is rotatably connected inside the connecting box 3. The end of the second transmission rod 7 near the first bevel gear 6 is equipped with the second bevel gear 8. The first bevel gear 6 meshes with the second bevel gear 8. The transmission gear 9 is sleeved on the end of the second transmission rod 7 away from the first bevel gear 6. The movable plate 10 is slidably connected inside the connecting box 3. A rack 11 is installed on the lower surface of the movable plate 10. The transmission gear 9 meshes with the rack 11. The auxiliary frame 12 is installed on the upper surface of the connecting box 3. A movable rod 13 is installed on the upper surface of the movable plate 10. The movable rod 13 passes through the inside of the connecting box 3. One end of the movable rod 13 passes through the connecting box 3 and enters the auxiliary frame 12. A buffer spring 14 is installed on the upper surface of the movable plate 10. The movable rod 13 passes through the inside of the buffer spring 14. The inclined plate 15 is slidably connected inside the auxiliary frame 12. The inclined surface of the inclined plate 15 faces backward. When the inclined plate 15 moves upward, it pushes the liquid on the upper surface down, exposes the drain pipe 17, and then the liquid enters the middle set of longer liquid distribution pipes 18 along the drain pipe 17. The top of the movable rod 13 is installed on the lower surface of the inclined plate 15.
[0025] like Figure 3As shown, the side of the auxiliary frame 12 is connected to the liquid storage box 16. The lower surface of the liquid storage box 16 is connected to the upper surface of the connecting frame 2. In the initial state, both the liquid storage box 16 and the auxiliary frame 12 contain liquid. The lower surface of the auxiliary frame 12 is connected to the drain pipe 17. After the inclined plate 15 moves upward, the drain pipe 17 can evenly discharge the liquid in the auxiliary frame 12 into the longer distribution pipe 18. It should be noted that the drain pipe 17 can only assist in draining the distribution pipes 18 located in the middle because the distribution pipes 18 located in the middle are longer and their front ends are far from the connecting box 1, so they need to be drained. The connecting box 1 is connected to the distribution pipe 18 inside, and the bottom end of the drain pipe 17 is connected to the distribution pipe 18 located in the middle.
[0026] like Figure 1 As shown, a tower body 19 is provided on the outer surface of the connecting box 1 and the liquid separator 18. A baffle plate 20 is installed inside the tower body 19. An air inlet pipe 21 is connected to the outer surface of the tower body 19. An air outlet pipe 22 is connected to the top of the tower body 19. The interior of the baffle plate 20 consists of a throat, a contraction section and a diffusion section. The baffle plate 20 can be used to change the direction of fluid flow or reduce the fluid velocity.
[0027] In this embodiment, initially, the liquid exists within the auxiliary frame 12 and the storage box 16. When the liquid is extracted, the liquid in the storage box 16 moves downward along the inside of the connecting frame 2 into the connecting box 1. The downward flow of the liquid in the storage box 16 pushes the blade 5 to rotate. The rotation of the blade 5 drives the first transmission rod 4 to rotate, which in turn drives the first bevel gear 6 to rotate. The rotation of the first bevel gear 6 drives the second bevel gear 8 to rotate, which in turn drives the second transmission rod 7 to rotate. The rotation of the second transmission rod 7 drives the transmission gear 9 to rotate, and the rotation of the transmission gear 9 meshes with the rack 11 and drives... As it moves upward, the rack 11 moves upward, causing the moving plate 10 to move upward. The moving plate 10 moves upward along the inside of the connecting box 3. The moving plate 10 moves upward, causing the moving rod 13 to move upward. The moving plate 10 moves upward, compressing the buffer spring 14. The moving rod 13 moves upward, causing the inclined plate 15 to move upward. The inclined plate 15 moves upward, exposing the drain pipe 17, so that the liquid in the auxiliary frame 12 enters the liquid distribution pipe 18 along the drain pipe 17. At the same time, the connecting box 1 distributes some of the liquid into the liquid distribution pipe 18, and then discharges it through the liquid distribution pipe 18 to spray the inside of the tower body 19.
[0028] After the liquid in the connecting frame 2 has drained, the buffer spring 14 rebounds, causing the moving plate 10 to move downward along the connecting box 3. The downward movement of the moving plate 10 causes the moving rod 13 to move downward, and the downward movement of the moving rod 13 causes the inclined plate 15 to move downward, thus resetting the inclined plate 15. The downward movement of the moving plate 10 causes the rack 11 to move downward, and the downward movement of the rack 11 causes the transmission gear 9 to reverse. The reverse movement of the transmission gear 9 causes the second transmission rod 7 to rotate, and the rotation of the second transmission rod 7 causes the second bevel gear 8 to rotate. The rotation of the second bevel gear 8 causes the first bevel gear 6 to rotate, and the rotation of the first bevel gear 6 causes the first transmission rod 4 to rotate, thus restoring the blade 5 to its initial position.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
