Description

Technical Field

[0001] This utility model relates to the field of zinc oxide desulfurization technology, specifically to a zinc oxide desulfurization tower. Background Technology

[0002] Sulfur dioxide is an air pollutant that has adverse effects on human health and air quality. Zinc oxide, as a desulfurizing agent, can effectively capture and fix sulfur dioxide, converting it into relatively stable zinc sulfate compounds, thereby achieving the purpose of removing sulfur dioxide from the gas. In order to improve air quality and protect public health, zinc oxide desulfurization towers are also one of the more commonly used desulfurization methods.

[0003] The existing zinc oxide desulfurization tower outputs gas from the tower body inlet and then uses a water pump to draw zinc oxide into the spray pipe for desulfurization by spraying.

[0004] Existing zinc oxide desulfurization towers can only spray zinc oxide slurry in a fixed direction, which results in some areas inside the desulfurization tower not being fully covered by the slurry. The fixed spraying position causes the sprayed slurry to impact a specific area inside the desulfurization tower for a long time, and the tower wall, supporting structure and other parts in that area will be subjected to continuous erosion and wear. To address this, we propose a zinc oxide desulfurization tower. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a secondary zinc oxide desulfurization tower that can evenly spray the secondary zinc oxide slurry to all areas of the desulfurization tower, avoid spray dead zones, improve the secondary zinc oxide desulfurization efficiency, extend the service life of the spray pipes and related equipment, and reduce the frequency of equipment maintenance and replacement, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zinc oxide desulfurization tower, including a bottom plate, a slurry pool on the upper surface of the bottom plate, a tower body at the top of the slurry pool, a spray pipe rotatably connected inside the tower body, an air inlet on the outside of the tower body, a protective cover on the outside of the tower body, and a rotating mechanism.

[0007] Rotating mechanism: It includes a gear, a rotating column, and a sector gear. The right end of the spray pipe extending out of the tower body is fixedly connected to the gear. The top of the left inner wall of the protective cover is rotatably connected to the rotating column. The left end of the rotating column is fixedly connected to the sector gear. The sector gear meshes with the gear, which can evenly spray the secondary zinc oxide slurry to all areas of the desulfurization tower, avoid spray dead zones, improve the secondary zinc oxide desulfurization efficiency, extend the service life of the spray pipe and related equipment, and reduce the frequency of equipment maintenance and replacement.

[0008] Furthermore, a microcontroller is installed on the outside of the base plate. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the rotating mechanism also includes a rotating column, a rotating block, a sliding column, and a strip frame. The rotating column is rotatably connected to the middle of the left inner wall of the protective cover. The rotating block is fixedly connected to the left end of the rotating column. The sliding column is rotatably connected to the bottom of the left side of the rotating block. A strip frame is sleeved on the outside of the rotating column. The outside of the sliding column is slidably connected to the inner wall of the strip frame to achieve stable rotation.

[0010] Furthermore, it also includes a motor, which is located on the right side of the protective cover. The left end of the motor's output shaft is fixedly connected to the right end of the rotating column, and the input end of the motor is electrically connected to the output end of the microcontroller to provide rotation drive.

[0011] Furthermore, a rotary joint is fixedly connected to the connection port extending from the left end of the spray pipe to the outside of the tower body. A connecting pipe is fixedly connected to the rotating end of the rotary joint, and the bottom end of the connecting pipe is connected to the inside of the slurry tank to realize the rotation of the spray pipe.

[0012] Furthermore, a water pump is connected in series with the outside of the connecting pipe, and the input end of the water pump is electrically connected to the output end of the microcontroller to ensure a sufficient supply of zinc oxide.

[0013] Furthermore, a demister is provided at the upper part of the tower body, and the demister is provided with evenly distributed corrugated plates to block moisture in the treated gas.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This zinc oxide desulfurization tower has the following advantages:

[0015] The motor drives the rotating column to rotate, causing the sliding column to slide within the strip frame, which in turn drives the rotating column to start rotating, causing the sector gear to swing back and forth. Through the meshing gears, the spray pipe rotates and sprays. The spray pipe can spray zinc oxide slurry in multiple directions, ensuring that no area inside the desulfurization tower is not fully covered by the slurry. The rotating spray pipe also reduces the erosion and wear on the inner wall of the tower, extending the service life of the zinc oxide desulfurization tower. Attached Figure Description

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 This embodiment provides a technical solution: a zinc oxide desulfurization tower, including a base plate 1, a slurry pool 2 on the upper surface of the base plate 1, a tower body 3 at the top of the slurry pool 2, a spray pipe 4 rotatably connected inside the tower body 3, an air inlet 5 on the outside of the tower body 3, a protective cover 6 on the outside of the tower body 3, and a rotating mechanism 7. A microcontroller 13 is installed outside the base plate 1, with its input terminal electrically connected to an external power source. A rotary joint 9 is fixedly connected to the left end of the spray pipe 4 at the connection port outside the tower body 3. A connecting pipe 10 is fixedly connected to the rotating end of the rotary joint 9. The bottom end of the connecting pipe 10 is connected to the inside of the slurry pool 2. A water pump 11 is connected in series outside the connecting pipe 10, with its input terminal electrically connected to the output terminal of the microcontroller 13. A demister 12 is installed at the upper inside of the tower body 3, and the demister 12 has uniformly distributed waveforms inside. When using the zinc oxide desulfurization tower, the zinc oxide solution is added into the slurry tank 2, and the exhaust port is connected to the air inlet 5 so that the gas to be desulfurized is discharged into the tower body 3 through the air inlet 5. Under the control of the microcontroller 13, the water pump 11 and the motor 8 start to run. The water pump 11 draws the zinc oxide solution into the spray pipe 4. The desulfurized gas automatically floats up and contacts the demister 12. The corrugated plate in the demister 12 blocks the liquid in the gas. The treated gas is discharged through the upper outlet, and the blocked liquid falls into the slurry tank 2. When the gas with droplets flows through the demister, the gas can change its flow direction relatively smoothly due to its own fluidity and move forward along the channel set by the demister. However, the droplets have relatively large inertia and cannot change their direction as quickly as the gas when the flow direction changes.

[0024] Rotating mechanism 7 includes a gear 71, a rotating column 72, and a sector gear 73. The right end of the spray pipe 4 extending from the tower body 3 is fixedly connected to the gear 71. The top of the left inner wall of the protective cover 6 is rotatably connected to the rotating column 72, and the left end of the rotating column 72 is fixedly connected to the sector gear 73, which meshes with the gear 71. The rotating mechanism 7 also includes a rotating column 74, a rotating block 75, a sliding column 76, and a strip frame 77. The middle of the left inner wall of the protective cover 6 is rotatably connected to the rotating column 74, and the left end of the rotating column 74 is fixedly connected to the rotating block 75. The bottom left side of the rotating block 75 is rotatably connected to the sliding column 76. The rotating column 72 is fitted with a strip frame 77. The outer side of column 76 is slidably connected to the inner wall of strip frame 77. It also includes motor 8, which is located on the right side of protective cover 6. The left end of the output shaft of motor 8 is fixedly connected to the right end of rotating column 74. The input end of motor 8 is electrically connected to the output end of microcontroller 13. When motor 8 starts to run, the output shaft will drive rotating column 74 to start rotating, so that the rotating block 75 at the left end of rotating column 74 drives the sliding column 76 on the left side to slide inside strip frame 77, thereby driving rotating column 72 to rotate, so that sector gear 73 starts to swing. Through meshing gear 71, spray pipe 4 starts to rotate during spraying, so that zinc oxide is fully mixed with the gas to be desulfurized.

[0025] The working principle of the zinc oxide desulfurization tower provided by this utility model is as follows: When using the zinc oxide desulfurization tower, zinc oxide solution is added into the slurry tank 2. The exhaust port is connected to the air inlet 5 so that the gas to be desulfurized is discharged into the tower body 3 through the air inlet 5. Under the control of the microcontroller 13, the water pump 11 and the motor 8 start to operate. The water pump 11 draws the zinc oxide solution into the spray pipe 4 and sprays it out through the nozzles on the spray pipe 4. The motor 8 starts to operate, and the output shaft drives the rotating column 74 to start rotating. The rotating block 75 at the left end of the rotating column 74 drives the sliding column 76 on the left side to slide inside the strip frame 77, thereby driving the rotating column. Rotation 72 causes the sector gear 73 to begin oscillating. Through the meshing gear 71, the spray pipe 4 begins to rotate during the spraying process, allowing the zinc oxide to be fully mixed with the gas to be desulfurized. The desulfurized gas automatically floats up and contacts the demister 12. When the gas containing mist flows through the demister 12 at a certain speed, due to the inertial impact of the gas, the mist collides with the corrugated plate and the droplets are agglomerated. When the droplets are so large that their own weight exceeds the resultant force of the gas's upward force and the liquid's surface tension, the droplets are separated from the surface of the corrugated plate. The treated gas is discharged through the outlet at the top of the tower body 3, and the blocked liquid falls into the interior of the slurry pool 2.

[0026] It is worth noting that the microcontroller 13, water pump 11 and motor 8 disclosed in the above embodiments can be selected as EFR32MG12 for microcontroller 13 and D180M-0160030B-E for motor 8. The microcontroller 13 controls the operation of water pump 11 and motor 8 using methods commonly used in the prior art.
