Description

Technical Field

[0001] This invention relates to the field of wastewater purification technology, and in particular to a multi-layer fluidized bed desulfurization wastewater chlorine removal adsorption tower. Background Technology

[0002] The multi-layer fluidized bed desulfurization wastewater chlorine removal adsorption tower is a device that utilizes fluidization technology to achieve efficient adsorption and removal of chloride ions from desulfurization wastewater in a multi-layer bed structure.

[0003] Fluidized bed adsorption towers contain multiple fluidized beds filled with adsorption packing material. This packing material has a limited lifespan and needs to be replaced periodically. In existing technologies, adsorption towers do not have the function of quickly removing the packing material from each fluidized bed layer. The packing material must be removed layer by layer. This process is not only time-consuming and labor-intensive, increasing the time cost of equipment downtime maintenance, but also may cause component wear or seal failure due to frequent disassembly and installation of the fluidized bed structure, thereby affecting the overall stability and reliability of the equipment.

[0004] Therefore, a multi-layer fluidized bed desulfurization wastewater chlorine removal adsorption tower needs to be designed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer fluidized bed desulfurization wastewater dechlorination adsorption tower.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-layer fluidized bed desulfurization wastewater chlorine removal adsorption tower includes a purification tower with an inlet pipe and an outlet pipe. The inlet pipe is located below the outlet pipe. The purification tower is equipped with a fluidizing assembly consisting of three fluidizing structures arranged in a straight line along the height of the purification tower. Each fluidizing structure includes a water tank. The inlet pipe is connected to the lower water tank via a first corrugated pipe, and the outlet pipe is connected to the upper water tank via a second corrugated pipe. Adjacent water tanks are connected by pipe fittings.

[0007] Each of the water tanks is equipped with a flipping component on its bottom surface and a moving component on its side surface. The purification tower is equipped with a driving component and a time-delay reset component.

[0008] As a preferred embodiment of the present invention, the pipe fitting includes a connecting pipe and two third corrugated pipes. The connecting pipe has a U-shaped structure, and the two third corrugated pipes are respectively connected to both ends of the connecting pipe. The two third corrugated pipes are respectively connected to two adjacent water tanks.

[0009] As a preferred embodiment of the present invention, the fluidization structure further includes two guide rods, two guide blocks, and two first springs. The two guide rods are fixed inside the purification tower, and the two guide blocks are respectively fixed on both sides of the water tank. The two guide blocks are slidably sleeved on the two guide rods. One end of each of the two first springs is connected to the water tank, and the other end of each of the two first springs is connected to the inner wall of the purification tower. The bottom surface of the water tank is open, and each water tank is filled with packing material.

[0010] As a preferred embodiment of the present invention, the flipping assembly includes several rotating shafts, all of which are rotatably mounted on a water tank. A gear is fixedly fitted at the end of each rotating shaft, and a blade is fixedly fitted on each rotating shaft. The blades are located at the bottom opening of the water tank. The flipping assembly also includes two baffles, both of which are fixed inside the water tank.

[0011] As a preferred embodiment of the present invention, the moving component includes a slide rail and several racks. The slide rail is fixed to the side of the water tank, and a slide block is slidably disposed on the slide rail. The several racks respectively mesh with several gears, one of the racks is fixed on the slide block, and a crossbar is fixed together on the several racks. The crossbar passes through the purification tower and is slidably connected to the purification tower.

[0012] As a preferred embodiment of the present invention, each of the racks is fitted to the side of the water tank.

[0013] As a preferred embodiment of the present invention, the driving assembly includes a first vertical plate and a second vertical plate. The first vertical plate is arranged on one side of the purification tower. Three top rods are fixed to the side of the first vertical plate. Each top rod passes through the purification tower and is slidably connected to the purification tower. The three top rods are respectively positioned opposite several water tanks. The second vertical plate is fixed to one end of several crossbars located outside the purification tower. A connecting rod is fixed to the side of the first vertical plate. The end of the connecting rod away from the first vertical plate is positioned opposite the second vertical plate.

[0014] As a preferred embodiment of the present invention, the first vertical plate is positioned directly opposite the eccentric wheel.

[0015] As a preferred embodiment of the present invention, the purification tower is provided with a delayed reset assembly, the delayed reset assembly including a sealing cylinder, the sealing cylinder being fixed to the tower body of the purification tower by a fixing rod, the sealing cylinder containing oil, a sliding plug being slidably disposed inside the sealing cylinder, the sliding plug having a through hole, a moving rod being fixed to the side of the sliding plug, the end of the moving rod away from the sliding plug extending to the outside of the sealing cylinder, the sliding plug and the sealing cylinder being connected by a second spring, and the end of the moving rod located outside the sealing cylinder being connected to a second vertical plate by an installation rod.

[0016] As a preferred embodiment of the present invention, the purification tower is provided with an inspection door.

[0017] The present invention has the following beneficial effects: 1. By setting up structures such as moving components and driving components, when it is necessary to replace the packing, the motor is started to drive the eccentric wheel to rotate, which can make the water tank vibrate. At the same time, the blades are controlled to rotate and open, and the packing in the water tank can quickly fall to the bottom of the purification tower, realizing the rapid collection and replacement of the packing. The operation is convenient and improves work efficiency. 2. By setting an eccentric wheel, the first vertical plate vibrates. The vibration is transmitted to several water tanks through several push rods, which in turn causes the water tanks to vibrate. The vibration of the water tanks helps the packing material to fall downward through several open blades, thus avoiding the accumulation and blockage of the packing material. 3. By setting a delayed reset component, the damping effect generated by the oil and the through hole is used to prevent the second vertical plate from resetting immediately, but to reset slowly. Under the action of the eccentric wheel, the connecting rod pushes the second vertical plate at a high frequency to keep it in a specific position, keeping the blade open and facilitating the continuous falling of the packing, thus further optimizing the packing replacement process.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: This example describes a multi-layer fluidized bed desulfurization wastewater chlorine removal adsorption tower, as disclosed in this example. Figure 1-8 The system includes a purification tower 1, which is equipped with an inlet pipe 13 and an outlet pipe 14. The inlet pipe 13 is used for water supply, and the outlet pipe 14 is used for drainage. The inlet pipe 13 is located below the outlet pipe 14. The purification tower 1 is equipped with a fluidization assembly, which consists of three fluidization structures arranged in a straight line along the height of the purification tower 1. Each fluidization structure includes a water tank 2. The inlet pipe 13 is connected to the lower water tank 2 via a first corrugated pipe 131, and the outlet pipe 14 is connected to the upper water tank 2 via a second corrugated pipe 141. Adjacent water tanks 2 are connected by pipe fittings, including connecting pipes 2. 4. Two third corrugated pipes 241 are connected to the two ends of the connecting pipe 24. The two third corrugated pipes 241 are connected to the two adjacent water tanks 2. During purification, wastewater enters the lower water tank 2 through the inlet pipe 13. After the lower water tank 2 is full, it enters the middle water tank 2 through the corresponding connecting pipe 24. After the middle water tank 2 is full, it enters the upper water tank 2 through the corresponding connecting pipe 24. Finally, it flows out through the drain pipe. Each water tank 2 is equipped with packing material. During the flow of wastewater in the water tank 2, it comes into full contact with the packing material. The packing material adsorbs the pollutants in the wastewater, realizing the fluidization effect.

[0022] The fluidization structure also includes two guide rods 21, two guide blocks 22, and two first springs 23. The two guide rods 21 are fixed inside the purification tower 1. The two guide blocks 22 are fixed on both sides of the water tank 2, and each guide block 22 is slidably fitted onto the two guide rods 21. The arrangement of the two guide rods 21 and the two guide blocks 22 together provides constraint for the movement of the water tank 2. One end of each of the two first springs 23 is connected to the water tank 2, and the other end of each of the two first springs 23 is connected to the inner wall of the purification tower 1. The two first springs 23 are used for the vibration of the water tank 2. The bottom surface of the water tank 2 has an open structure, and a tilting assembly is provided on the bottom surface of the water tank 2. The tilting assembly includes several rotating shafts 31, which are rotatably mounted on the water tank 2. A gear 311 is fixedly fitted at the end of each rotating shaft 31, and a blade 32 is fixedly fitted on each rotating shaft 31. The blades 32 are located at the bottom opening of the water tank 2. Figure 6 As shown, when two adjacent blades 32 are in contact with each other, several blades 32 form a closed state, that is, several blades 32 together block the bottom opening of the water tank 2. At this time, the water flow and the packing cannot leave the water tank 2. When several blades 32 are in a vertical state, several blades 32 form an open state, as shown. Figure 7 As shown, there is a gap between two adjacent blades 32 at this time, and the packing can fall out of the water tank 2 through the gap. The flipping assembly also includes two baffles 33, both of which are fixed inside the water tank 2. When several blades 32 rotate to the closed state, the blades 32 at both ends contact the two baffles 33 respectively. The purpose of this design is to ensure the sealing effect of several blades 32 in the closed state on the water tank 2.

[0023] Each water tank 2 has a movable component on its side for driving several blades 32 to rotate. The movable component includes a slide rail 41 and several racks 43. The slide rail 41 is fixed to the side of the water tank 2, and a slide block 42 is slidably mounted on the slide rail 41. Several racks 43 mesh with several gears 311 respectively. One rack 43 is fixed on the slide block 42. A crossbar 44 is fixed to several racks 43. The crossbar 44 passes through the purification tower 1 and is slidably connected to the purification tower 1. When the crossbar 44 moves, it drives several racks 43 to move. When several racks 43 move, they drive several gears 311 to rotate, thereby controlling several rotating shafts 31 to flip. The purification tower 1 is equipped with a drive assembly, which includes a first vertical plate 52 and a second vertical plate 53. The first vertical plate 52 is arranged on one side of the purification tower 1 and is positioned directly opposite the eccentric wheel 12. Three push rods 51 are fixed to the side of the first vertical plate 52. Each push rod 51 passes through the purification tower 1 and is slidably connected to the purification tower 1. The three push rods 51 are respectively positioned directly opposite several water tanks 2. The second vertical plate 53 is fixed to one end of several crossbars 44 located outside the purification tower 1. A connecting rod 54 is fixed to the side of the first vertical plate 52, and the end of the connecting rod 54 away from the first vertical plate 52 is positioned directly opposite the second vertical plate 53.

[0024] When the packing material in each water tank 2 needs to be replaced, the staff first empties the water in the purification tower 1, then starts the motor 11. When the motor 11 runs, it drives the eccentric wheel 12 to rotate. As the eccentric wheel 12 rotates, it continuously pushes the first vertical plate 52 to move. When the first vertical plate 52 moves, it drives several top rods 51 on it to move. When the top rods 51 move, they push the corresponding water tank 2. At the same time, with the elastic force of the first spring 23, several water tanks 2 vibrate. In addition, when the first vertical plate 52 moves, it also drives the connecting rod 54 to move, which in turn drives the second vertical plate 53 to move. When the second vertical plate 53 moves, it drives several horizontal bars 44 to move. Several racks 43 on the horizontal bars 44 move accordingly, thereby controlling several rotating shafts 31 to rotate. When the rotating shafts 31 rotate, they drive the blades 32 to rotate, causing the blades 32 to rotate from a closed state to an open state. In this case, the packing material in the water tank 2 will fall down through the gap between the blades 32 and finally fall to the bottom of the purification tower 1, realizing the rapid collection of the packing material and facilitating its replacement.

[0025] In addition, under the action of the eccentric wheel 12, the first vertical plate 52 vibrates. The vibration is transmitted to the water tanks 2 through the push rods 51, which in turn causes the water tanks 2 to vibrate. The vibration of the water tanks 2 helps the packing material to fall down through the open blades 32, thus avoiding the accumulation and blockage of the packing material.

[0026] It is worth noting that the arrangement of the first corrugated pipe 131, the second corrugated pipe 141 and the third corrugated pipe 241 facilitates the vibration of the water tank 2 and avoids the arrangement of rigid pipes affecting the vibration of the water tank 2.

[0027] Example 2: Based on Example 1, this example discloses a multi-layer fluidized bed desulfurization wastewater chlorine removal adsorption tower, such as... Figure 8 As shown, a delayed reset assembly is provided on the purification tower 1. The delayed reset assembly includes a sealing cylinder 61, which is fixed to the tower body of the purification tower 1 by a fixing rod 611. Oil is stored inside the sealing cylinder 61, and a sliding plug 62 is slidably disposed inside the sealing cylinder 61. The sliding plug 62 has a through hole 621 and is immersed in the oil. A moving rod 64 is fixed to the side of the sliding plug 62, and the end of the moving rod 64 away from the sliding plug 62 extends to the outside of the sealing cylinder 61. The sliding plug 62 and the sealing cylinder 61 are connected by a second spring 63. The sealing cylinder 61 has a hole adapted to the moving rod 64, and the moving rod 64 is slidably connected in the hole. The end of the moving rod 64 located outside the sealing cylinder 61 is connected to the second vertical plate 53 by a mounting rod 65. When the second vertical plate 53 moves, the second vertical plate 53 can drive the moving rod 64 to move through the mounting rod 65. When the moving rod 64 moves, it drives the sliding plug 62 to move, so that the sliding plug 62... Moving in the oil, the slide plug 62 has a through hole 621. During the movement of the slide plug 62, the oil will pass through the through hole 621. The through hole 621 allows the slide plug 62 to move inside the sealing cylinder 61. The oil and the through hole 621 cooperate to provide damping for the movement of the slide plug 62. When the first vertical plate 52 drives the connecting rod 54 away from the second vertical plate 53, the damping effect prevents the second vertical plate 53 from immediately following the connecting rod 54 to reset, but to reset slowly. Because the second vertical plate 53 resets slowly, and the first vertical plate 52 and the connecting rod 54 rotate rapidly under the action of the eccentric wheel 12, the connecting rod 54 will push the second vertical plate 53 at a high frequency, so that the second vertical plate 53 will only reset with a small amplitude, thus keeping the second vertical plate 53 in a specific position. In this case, the positions of several racks 43 and several gears 311 are also fixed, and finally the several blades 32 are kept open to facilitate the continuous falling of the packing.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
