Description

Technical Field

[0001] This utility model relates to the field of chemical environmental protection equipment technology, and in particular to an acid gas recovery tower. Background Technology

[0002] Acid gas recovery refers to the technology of recycling large quantities of acidic waste liquids or gases generated during industrial production processes. These waste liquids and gases may contain varying concentrations of metal ions and useful acids. Direct discharge not only wastes resources and pollutes the environment but also poses a threat to human health. Acid gas recovery technology can effectively reduce the emission of waste acid, lower the risk of environmental pollution, and conserve resources and energy.

[0003] A search revealed Chinese publication number CN218944703U, which discloses an acid gas recovery tower device. The device includes an inlet pipe connected to a PVC pipe connector at its bottom, a PP circulating water tank connected to the bottom of the PVC pipe connector, a PVC double-handle ball valve connected to one side of the PP circulating water tank via a pipe, and an acid-alkali resistant self-priming magnetic pump connected to one end of the PVC double-handle ball valve via a pipe. The top of the acid-alkali resistant self-priming magnetic pump has a water outlet. Through the design of the acid-alkali resistant self-priming magnetic pump, PVC double-handle ball valve, PVC check valve, filter, inlet pipe, PVC pipe connector, PP circulating water tank, turbine nozzle, and pipe baffle, the acidity of the gas entering the acid mist tower can be significantly reduced. The cleanliness and acidity of the washed water meet the requirements for reuse. The maintenance costs of the acid mist tower and the acid cost are effectively controlled. The device operates stably and does not affect the ventilation effect of the acid mist tower.

[0004] The aforementioned patent states in its specification that "the turbine nozzle 8 is installed vertically downwards, and the dispersion atomization area covers the entire acid mist tower pipeline. The turbine nozzle 8 is located inside the air inlet pipe 5. This structure can significantly reduce the acidity of the gas entering the acid mist tower and the water after washing." However, during use, the spray rate is slow, and some acidic gases fail to neutralize with the alkali solution and are directly discharged into the atmosphere with the exhaust gas, resulting in a reduced recovery effect. Therefore, in order to address the above shortcomings, an acid gas recovery tower is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an acid gas recovery tower, which aims to improve the problem that in the existing technology, some acid gas recovery processes may result in incomplete spraying, leading to a reduction in recovery efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas recovery tower includes a recovery tower, an outlet pipe fixedly connected to the top of the recovery tower, an inlet pipe fixedly connected to the front end of the bottom of the recovery tower, a filter disassembly mechanism slidably connected to the inner wall of the inlet pipe, a water spraying mechanism fixedly connected to the rear side of the recovery tower, the water spraying mechanism including a drive assembly, the front side of the drive assembly fixedly connected to the rear side of the recovery tower, multiple pipe supports fixedly connected inside the drive assembly, multiple water outlet pipes fixedly connected inside the pipe supports, a positioning plate fixedly connected to the outside of the water outlet pipes, a spraying cylinder rotatably connected to the outside of the positioning plate, multiple spray heads fixedly connected to the bottom end of the spraying cylinder, a connecting frame fixedly connected to the inner wall of the spraying cylinder, a column fixedly connected to the middle of the side of the connecting frame near the water outlet pipes, multiple rotating blades fixedly connected to the outside of the column, and multiple filter plates fixedly connected inside the recovery tower.

[0008] Furthermore, the inlet pipe inside the recovery tower is used for acid gas input. Its internal filter disassembly mechanism can perform preliminary filtration of the incoming acid gas and facilitate maintenance and cleaning. The drive component provides power to the whole system, the pipe rack supports the water outlet pipe, which is responsible for water delivery, the positioning plate allows the spray cylinder to rotate flexibly, and multiple spray heads are used to spray water flow to react with the acid gas. The connecting frame and column fix the rotating blades. The water flow impacts the blades, causing the spray cylinder to rotate and expand the spray range. Multiple filter plates inside the recovery tower further filter and purify the mixed gas after the reaction.

[0009] As a further description of the above technical solution:

[0010] The filter disassembly mechanism includes an arc-shaped plate, the outer side of which is slidably connected to the inside of the air intake pipe. A rotating rod is rotatably connected to the inner wall of the arc-shaped plate. A handle is fixedly connected to the side of the rotating rod away from the arc-shaped plate. A transmission plate is fixedly connected to the side of the rotating rod away from the handle. A sliding column is slidably connected to the inner wall of the transmission plate. Limit blocks are fixedly connected to both sides of the sliding column. A rotating plate is fixedly connected to the opposite sides of the two sliding columns. An opening plate is rotatably connected to the opposite ends of the two rotating plates. Two side plates are fixedly connected to both sides of the inner wall of the arc-shaped plate. A reset assembly is fixedly connected to the opposite sides of the multiple side plates. Support plates are fixedly connected to both sides of the opening plate. A filter plate is fixedly connected to the side of the arc-shaped plate away from the handle.

[0011] Furthermore, the arc-shaped plate can slide inside the intake pipe, facilitating installation and disassembly. Rotating the handle drives the rotating rod and transmission plate to rotate. When the transmission plate rotates, the sliding column slides on its inner wall. Limiting blocks on both sides of the sliding column ensure its sliding stability. The sliding column drives the rotating plate to rotate, and the rotation of the rotating plate causes the opening plate to move accordingly. The reset component on the side plate can restore the mechanism to its initial state after operation. The support plates on both sides of the opening plate play a supporting and auxiliary positioning role. The filter plate on the side of the arc-shaped plate away from the handle can perform preliminary filtration of the acid gas entering the intake pipe, removing some impurities and larger particles, ensuring the effectiveness of subsequent acid gas recovery treatment.

[0012] As a further description of the above technical solution:

[0013] The drive assembly includes a water pump, the front side of which is fixedly connected to the side of the recovery tower near the water pump, the input end of which is fixedly connected to a water inlet pipe, and the output end of which is fixedly connected to a transport pipe.

[0014] Furthermore, the water pump of the drive component is fixed on one side of the recovery tower. It draws water from an external water source through the inlet pipe and then uses the transport pipe to deliver the water to subsequent pipe racks, outlet pipes and other components, providing power support for the entire sprinkler mechanism. This ensures that the water can smoothly reach the spray cylinder and spray head, achieving the spray treatment of acid gas in the recovery tower, promoting the reaction between acid gas and water, and thus achieving the purpose of acid gas recovery and purification.

[0015] As a further description of the above technical solution:

[0016] The transport pipe is internally fixedly connected to the outside of the multiple pipe racks, the water outlet pipe is externally rotatably connected to the inside of the spray cylinder, a viewing window is fixedly connected to the top front end of the recovery tower, and a discharge pipe is fixedly connected to the bottom end of the recovery tower.

[0017] Furthermore, the transport pipe is connected to multiple pipe racks, which can stably deliver the water output from the water pump to each outlet pipe, ensuring the water supply for the sprinkler system. The outlet pipe is rotatably connected to the spray cylinder, allowing the spray cylinder to rotate flexibly, which facilitates expanding the spray range and improving the treatment effect of acid gas. The viewing window at the top of the recovery tower allows operators to observe the acid gas recovery and treatment status inside the tank. The discharge pipe at the bottom of the recovery tower is used to discharge the substances that have been treated and precipitated or generated by the reaction, maintaining the working environment inside the recovery tower and ensuring the continuous and stable operation of the acid gas recovery device.

[0018] As a further description of the above technical solution:

[0019] Each of the multiple reset components includes a positioning rod, and the far side of the multiple side plates is fixedly connected to the near side of the multiple positioning rods, and a spring is sleeved on the outside of the positioning rods.

[0020] Furthermore, the positioning rod in the multiple reset components is fixedly connected to the side plate at one end, serving as a support and positioning element. The spring sleeved on the outside of the positioning rod has the characteristic of elastic deformation. When the external force is released, the spring will use its own elastic restoring force to push the side plate and the connected components back to the initial position, thereby enabling the filter disassembly mechanism to return to its original state, ensuring the stability of its structure and the normal operation of the next operation, and facilitating the continuous and stable preliminary filtration of acid gas by the acid gas recovery device.

[0021] As a further description of the above technical solution:

[0022] The positioning rod is slidably connected to the outside of the support plate, and the two opening plates are slidably connected to the front and rear ends of the air intake pipe respectively.

[0023] Furthermore, the positioning rod can slide inside the support plate, allowing the support plate and the connected opening plate to move when force is applied. One end of the two opening plates is slidably connected to the inside of the front and rear ends of the air intake pipe. When the opening plates are moved by operations such as rotating the handle.

[0024] As a further description of the above technical solution:

[0025] The transmission plate has strip-shaped openings at both the front and rear ends. The two sliding columns are slidably connected to the inside of the two strip-shaped openings, and the two limiting blocks are slidably connected to the inside of the strip-shaped openings.

[0026] Furthermore, the strip-shaped opening provides space for the sliding column to slide, while also providing support for the sliding of the limiting block.

[0027] As a further description of the above technical solution:

[0028] The exterior of the two opening plates is slidably connected to the interior of the front and rear ends of the arc-shaped plate, and the far sides of the plurality of support plates are fixedly connected to the near ends of the plurality of springs.

[0029] Furthermore, the two open plates slide within the front and rear ends of the arc-shaped plate, allowing the open plates to move flexibly within the space defined by the arc-shaped plate, while the connection between the multiple support plates and the springs allows the elastic force of the springs to act on the support plates.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, water flows out through multiple outlet pipes and impacts multiple rotating blades, which in turn drive the column to rotate, thereby driving the connecting frame to rotate. This, in turn, drives the spray cylinder to rotate under the support and restriction of the positioning plate, enabling it to drive multiple spray heads to rotate, thereby increasing the spraying range, avoiding uneven mixing, and improving the acid gas recovery effect.

[0032] 2. In this utility model, the rotating plate rotates around the pin inside the opening plate under the drive of the sliding column, causing the opening plate to slide until it slides away from the inner wall of the air intake pipe. During the sliding of the opening plate, it will drive the two support plates to slide and stretch the spring, allowing the spring to store elastic potential energy. Then, the support plates will give the opening plate a force in the opposite direction to reset it. After that, the arc plate can be removed, so that the grip can be replaced and repaired, thereby extending its service life. Attached Figure Description

A spring 4112 is sleeved on the outside of the positioning rod 4111, allowing the spring 4112 to be evenly stressed. Support plates 412 are fixedly connected to the left and right sides of the open plate 49, driving the two connected support plates 412 through the open plate 49. Synchronous sliding: The far sides of multiple support plates 412 are respectively fixedly connected to the near ends of multiple springs 4112. During the sliding process, the support plates 412 stretch the springs 4112, allowing the springs 4112 to store elastic potential energy, and then give the support plates 412 a force in the opposite direction to reset. The external slidable connection of the positioning rod 4111 is slidably connected to the inside of the support plate 412, providing support for the support plate 412, so that the support plate 412 can slide stably on the positioning rod 4111.

The top front end of the recovery tower 1 is fixedly connected to the viewing window 5, which allows the operator to observe the internal situation of the recovery tower 1.

[0049] Specifically, recovery tower 1 is used to contain and treat acid gas. The top of recovery tower 1 is connected to an outlet pipe 2 for discharging the treated gas, and the bottom front end is connected to an inlet pipe 3, which is the channel for acid gas to enter recovery tower 1. The inner wall of inlet pipe 3 is equipped with a filter disassembly mechanism 4 for quick disassembly. An arc-shaped plate 41 slides smoothly within inlet pipe 3, and its inner wall is rotatably connected to a rotating rod 42, ensuring stable rotation of the rotating rod 42. One side of the rotating rod 42 has a handle 43 for easy gripping and rotation by the operator, while the other side is connected to a transmission plate 44, which drives the plate to rotate and transmit power. The transmission plate 44 has rectangular slotted openings 45 at both ends, and a sliding column 46 is slidably connected to its inner wall. The sliding column 46 transmits force when the transmission plate 44 rotates. Limiting blocks 47 on both sides of the sliding column 46 prevent it from dislodging from the slotted openings 45, ensuring stable sliding within the openings. The sliding column 46 drives the rotating plate 48 to rotate. The movable plate 48 is rotatably connected to the open plate 49 via a pin, causing the open plate 49 to move linearly. The open plate 49 slides inside the front and rear ends of the arc plate 41 and the air inlet pipe 3, respectively, to realize the connection and fixation between the filter disassembly mechanism 4 and the air inlet pipe 3. Multiple side plates 410 are fixed on the left and right sides of the inner wall of the arc plate 41. The side plates 410 support the reset assembly 411. The positioning rod 4111 of the reset assembly 411 is fixed on the side plate 410, and a spring 4112 is sleeved on the outside to make it evenly stressed.

[0050] Reference Figure 1 , Figure 5 and Figure 6 A water spraying mechanism 6 is fixedly connected to the rear side of the recovery tower 1 for spraying treatment liquid into the recovery tower 1 to treat acid gas. The water spraying mechanism 6 includes a drive assembly 61, which provides power to the water spraying mechanism 6. The front side of the drive assembly 61 is fixedly connected to the rear side of the recovery tower 1 to provide power support for water spraying. The drive assembly 61 includes a water pump 611, which provides power for liquid transportation. The front side of the water pump 611 is fixedly connected to the side of the recovery tower 1 near the water pump 611 and is fixed by welding. To ensure that the water pump 611 can be stably installed on the recovery tower 1, the input end of the water pump 611 is fixedly connected to the water inlet pipe 612, which introduces the treatment liquid. The output end of the water pump 611 is fixedly connected to the transport pipe 613, which transports the treatment liquid to the subsequent components. The inside of the transport pipe 613 is fixedly connected to the outside of multiple pipe supports 62 and is fixed by welding process to ensure the stability of the pipe supports 62. The inside of the drive assembly 61 is fixedly connected to multiple pipe supports 62 to provide installation support for the pipe supports 62.

[0051] Multiple outlet pipes 63 are fixedly connected inside the pipe rack 62. These outlet pipes 63 transport the treated liquid to the spray cylinder 65. A positioning plate 64 is fixedly connected to the outside of each outlet pipe 63 via welding, providing stable support for the positioning plate 64. The spray cylinder 65 is rotatably connected to the outside of the positioning plate 64, providing support for it. Multiple spray heads 66 are fixedly connected to the bottom of the spray cylinder 65, spraying the treated liquid into the recovery tower 1 in a mist form. A connecting frame 67 is fixedly connected to the inner wall of the spray cylinder 65 via welding. The connecting frame 67 is supported by a column 68 fixedly connected to the middle of the side of the connecting frame 67 near the outlet pipe 63. The column 68 is fixedly connected by welding, thus providing support for the column 68. Multiple rotating blades 69 are fixedly connected to the outside of the column 68. The rotating blades 69 drive the column 68 to rotate under the impact of water flow. The rotational force is then transmitted to the spraying cylinder 65 through the connecting frame 67. Multiple filter plates 610 are fixedly connected inside the recovery tower 1. The filter plates 610 further filter the acid gas. The bottom end of the recovery tower 1 is fixedly connected to the discharge pipe 7, which is used to discharge the treated liquid.

[0052] Specifically, the water spraying mechanism 6 at the rear of the recovery tower 1 sprays treatment liquid into the recovery tower 1 to treat acid gas. The power for the water spraying mechanism 6 is provided by the drive assembly 61, which is fixed to the rear of the recovery tower 1. The water pump 611 in the drive assembly 61 is securely installed on the side of the recovery tower 1 closest to itself by welding, providing power for liquid transportation. The input end of the water pump 611 is connected to the inlet pipe 612 to introduce the treatment liquid, and the output end is connected to the transport pipe 613. The transport pipe 613 transports the treatment liquid to subsequent components. Multiple pipe supports 62 are fixed to the outside of the transport pipe 613 by welding. Multiple outlet pipes 63 are fixed inside the pipe supports 62. The outlet pipes 63 are responsible for transporting the treatment liquid to the spray cylinder 65. A positioning plate 64 is welded to the outside of the outlet pipe 63. The positioning plate 64 is rotatably connected to the spray cylinder 65 to provide support. Multiple spray heads 66 are fixed at the bottom of the spray cylinder 65, which can spray the treated liquid into the recovery tower 1 in the form of a spray. A connecting frame 67 is welded to the inner wall of the spray cylinder 65. A column 68 is welded to the middle of the connecting frame 67 near the outlet pipe 63. Multiple rotating blades 69 are fixed to the outside of the column 68. The water flow impacts the rotating blades 69, causing the column 68 to rotate. The rotational force is then transmitted to the spray cylinder 65 through the connecting frame 67. In addition, multiple filter plates 610 are fixed inside the recovery tower 1 to further filter the acid gas. A discharge pipe 7 is fixed at the bottom of the recovery tower 1 for discharging the treated liquid.

[0053] Working principle: First, acid gas is introduced into the recovery tower 1 through the inlet pipe 3. Simultaneously, the acid gas undergoes preliminary filtration through the filter plate 413. By gripping the handle 43 and applying rotational force, the rotating rod 42 rotates, which in turn rotates the transmission plate 44. This causes the two sliding columns 46 to slide towards each other, thereby causing the rotating plate 48 to slide. Then, the two opening plates 49 slide. Furthermore, the rotating plate 48, driven by the sliding columns 46, rotates around the pin inside the opening plate 49, causing the opening plate 49 to slide until it slides away from the inner wall of the inlet pipe 3. During the sliding of the opening plate 49, the two support plates 412 will slide and stretch the spring 4112, allowing the spring 4112 to store elastic potential energy. Then, the support plates 412 will apply a force in the opposite direction to the opening plate 49 to reset it. After that, the arc plate 41 can be removed to replace and repair the handle 43, thereby extending its service life. Conversely, when the force on the rotating rod 42 is released, the spring 4112 will reset and transmit the reset force to the opening plate 49, allowing the opening plate 49 to reset and slide into the interior of the intake pipe 3 to engage, thus completing the installation.

[0054] Then, the acid gas enters the interior of the recovery tower 1. At this time, the water pump 611 is started, so that the water inlet pipe 612 can draw water in and transport it through the transport pipe 613. Then it is transported to multiple pipe racks 62 and flows out through multiple water outlet pipes 63, impacting multiple rotating blades 69. The multiple rotating blades 69 can drive the column 68 to rotate, thereby driving the connecting frame 67 to rotate, which in turn drives the spray cylinder 65 to rotate under the support and restriction of the positioning plate 64. This allows it to drive multiple spray heads 66 to rotate, thereby increasing the spraying range and avoiding uneven mixing, thus improving the acid gas recovery effect. After the acid gas reacts with the alkaline water, it falls onto the filter plate 610 and will fall to the bottom of the recovery tower 1 over time. Then, by opening the valve on the discharge pipe 7, the turbid water inside the recovery tower 1 is discharged.
