Description

Technical Field

[0001] This invention relates to the field of electrocatalytic tail gas treatment technology, specifically to a safe and efficient electrocatalytic tail gas absorption and treatment device. Background Technology

[0002] Electrocatalysis technology, with its advantages of high efficiency and environmental friendliness, has been widely used in chemical, pharmaceutical, and fine chemical synthesis fields. However, in actual reaction processes, this technology often produces flammable, toxic, or highly corrosive byproduct gases. Direct emission of these gases not only poses safety hazards but also harms the environment and equipment. Therefore, a dedicated exhaust gas absorption and treatment device is required to render them harmless.

[0003] Traditional exhaust gas treatment methods mainly include direct emission, combustion treatment, and chemical absorption. Direct emission easily causes environmental pollution and poses significant safety hazards; combustion treatment has high energy consumption and is prone to secondary pollution. In recent years, with increasingly stringent environmental protection requirements, chemical absorption has gradually become the mainstream method for exhaust gas treatment. However, traditional chemical absorption methods only rely on simple spraying of absorbent liquid, resulting in short gas-liquid contact time and insufficient contact, leading to low exhaust gas treatment efficiency and low overall efficiency of the treatment device. Furthermore, in traditional devices, the absorbent liquid only flows in localized areas, with a limited spray range and uneven distribution, easily forming treatment dead zones within the tower, failing to achieve uniform distribution of the absorbent liquid, resulting in insufficient gas-liquid contact and consequently poor treatment device performance. In addition, impurities easily adhere to the surface of the internal flow channels, causing scaling and blockage, requiring regular manual cleaning and maintenance, which inconveniences operators and further reduces the ease of use of the treatment device.

[0004] Therefore, it is necessary to invent a safe and efficient electrocatalytic tail gas absorption and treatment device to solve the above problems. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] This embodiment provides a safe and efficient electrocatalytic tail gas absorption and treatment device;

[0032] Please see Figure 1 - Figure 8As shown, the system includes a processing tank 1, a processing trough 2 in the middle of the processing tank 1, a placement trough 3 in the middle of the processing trough 2, an air inlet 4 on the lower side of the processing trough 2, an air outlet 5 on the upper side of the processing trough 2, a filter plate 6 fixed on the lower side of the processing trough 2, a placement sieve frame 7 on the inner wall of the placement trough 3, and several packing materials 8 inside the placement sieve frame 7, a water ring vacuum pump 9 at the upper end of the processing tank 1, an ejector 10 at the upper end of the water ring vacuum pump 9, a circulation pump 11 on one side of the processing tank 1, an inlet pipe 12 at the inlet end of the circulation pump 11, an outlet pipe 13 at the outlet end of the circulation pump 11, a control cabinet 14 in the middle of the processing tank 1, a dilution pipe 15 on one side of the control cabinet 14, and a battery pack 16 on the other side of the processing tank 1. The control cabinet 14 is powered by the battery pack 16, providing power to the entire processing unit. The core components of the device are provided with stable power support to ensure continuous and stable operation of the equipment. The battery pack 16 used for power supply is a lead-acid battery pack 16, which has reliable emergency power supply capability. In the event of a sudden power outage, it can support the system to operate urgently for 15 minutes to ensure that the equipment can complete a safe shutdown operation and avoid equipment damage or exhaust gas leakage due to sudden power outage. At the same time, the control cabinet 14 adopts an explosion-proof design, equipped with an explosion-proof motor and intrinsically safe circuit. Working in coordination with the power supply system of the battery pack 16, it can not only prevent safety hazards caused by circuit faults, but also adjust the equipment operating parameters in real time through PID algorithm to ensure stable and efficient processing flow, further improving the safety and practicality of the device.

[0033] Please refer to it again. Figure 1 - Figure 8 As shown, the placement sieve frame 7 has several sieve holes in the middle. The diameter of the packing material 8 is larger than the diameter of the sieve holes. The outer surface of the placement sieve frame 7 is fixed to the inner wall of the placement trough 3. The water ring vacuum pump 9 is detachably installed at the air outlet 5 by bolts. The water ring vacuum pump 9 is connected to the ejector 10. The ejector 10 has an air outlet at its end. The circulation pump 11 is connected to the lower middle part of the treatment tank 1 through the liquid inlet pipe 12. The liquid inlet of the liquid inlet pipe 12 is located below the filter plate 6. The circulation pump 11 is connected to the upper side of the treatment tank 1 through the liquid outlet pipe 13. The dilution pipe 15 is connected to... The upper side of the treatment tank 1 is connected, and the water ring vacuum pump 9 and the ejector 10 are connected in series at the outlet end 5. It is not for conventional negative pressure suction, but is used as a safe dilution, pressure stabilization and explosion-proof emission unit for the treated exhaust gas. The two form a cooperative exhaust structure. The outlet end 5, the water ring vacuum pump 9 and the ejector 10 adopt a coaxial straight-through and progressively expanding flow channel design, which will not significantly increase the exhaust back pressure and will not cause the vacuum pump to overload. At the same time, it can form a stable micro negative pressure to prevent exhaust gas leakage and meet the requirements for safe treatment and emission of electrocatalytic exhaust gas.

[0034] The specific implementation process is as follows: First, the air inlet 4 at the bottom of the treatment tank 1 is connected to the air outlet of the electrocatalytic device through a connecting pipe. Then, the ejector 10 and the water ring vacuum pump 9 are started to form a negative pressure field on the upper side of the treatment tank 1. At this time, the waste gas generated by the electrocatalysis enters the treatment tank 2 of the treatment tank 1 from the air inlet 4 and floats upward under the action of negative pressure. At the same time, the control cabinet 14 is powered by the battery pack 16 to control the circulation pump 11 to start. The circulation pump 11 draws the absorbent liquid into the inlet pipe 12 and discharges it from the outlet pipe 13. The discharged absorbent liquid is sprinkled onto the placement screen 7 fixed on the inner wall of the placement tank 3 in the middle of the treatment tank 2, and wets the PP Pall ring packing 8 in the screen frame. Under the action of gravity, the absorbent liquid flows downward along the packing 8, and the upward-floating waste gas forms a countercurrent contact with the flowing absorbent liquid. As the core carrier for gas-liquid mass transfer, PP Pall ring packing 8 provides stable adhesion support for the absorbent liquid with its large specific surface area, forming a uniform liquid film. At the same time, it guides the exhaust gas to pass through evenly and extends the gas-liquid contact path, thereby achieving efficient gas-liquid contact and significantly improving the exhaust gas absorption efficiency.

[0035] The exhaust gas treated by the packing material 8 and the absorbent is monitored in real time by an infrared and catalytic combustion dual-mode sensor configured in the control cabinet 14. The control cabinet 14 adjusts the dilution airflow of the dilution pipe 15 through a PID algorithm to ensure that the concentration of the exhaust gas emitted from the upper side of the treatment tank 1 is maintained below the lower explosive limit. The control cabinet 14 adopts an explosion-proof design and is equipped with an explosion-proof motor and intrinsically safe circuit. The lead-acid battery pack 16 used for power supply can support the system's emergency operation for fifteen minutes to ensure safe shutdown of the equipment. After the above series of treatments, the exhaust gas is discharged normally from the opening of the ejector 10 under the continuous negative pressure of the ejector 10 and the water ring vacuum pump 9. At the same time, the absorbent flowing through the packing material 8 falls through the placement screen 7 to the filter plate 6 on the lower side of the treatment tank 2, and re-enters the circulation system after filtration, achieving a highly efficient purification effect. This not only ensures the safe discharge and stable operation of the treatment device, but also effectively improves the efficiency of the device.

[0036] Example 2

[0037] Please see Figure 1 - Figure 8 As shown, the function of evenly distributing the absorbent liquid has been added based on Example 1;

[0038] Please refer to it again. Figure 1 - Figure 8As shown, a fixing frame 17 is fixed to the liquid outlet end of the liquid outlet pipe 13. A support frame 18 is rotatably connected to the outer surface of the fixing frame 17. A frame groove 19 is opened in the middle of the support frame 18. Several through holes 20 are opened at the lower end of the frame groove 19. An impeller 21 is fixed to the upper inner wall of the frame groove 19. Several spray pipes 22 are fixed to the lower side of the support frame 18. Several spray holes 23 are opened in the middle of each spray pipe 22. The inner wall of the fixing frame 17 is fixed to the liquid outlet end of the liquid outlet pipe 13. The cross-section of the fixing frame 17 is circular. The outer surface of the fixing frame 17 is rotatably connected to the frame groove 19. The wall and the support frame 19 have an I-shaped cross-section. The impeller 21 is fixed to the upper side of the support frame 19 at its opposite end. The impeller 21 is arranged in a ring. Several spray pipes 22 are fixed to the lower side of the support frame 18. The spray pipes 22 are all inclined. Several spray holes 23 are inserted through the lower side of the spray pipes 22. The rotating support frame 18 and the spray pipes 22 work together to form the core structure for uniform distribution of the absorbent liquid, ensuring that the absorbent liquid can fully cover the 8 layers of packing. The support frame 18 rotates stably under the drive of the impeller 21. Several through holes 20 opened in the middle can allow some of the absorbent liquid to be distributed. The absorbent liquid is sprayed directly onto the packing material 8 placed in the middle of the screen frame 7, achieving uniform wetting of the packing material 8 in the middle. The remaining absorbent liquid flows along the flow channel of the support frame 18 into the spray pipe 22 that is tightly connected to it. The spray pipe 22 rotates synchronously with the support frame 18, and through several spray holes 23 opened in the pipe body, the absorbent liquid is evenly sprayed to the edge area of ​​the packing material 8 layer, completely eliminating dead corners in liquid distribution. The rotational movement of the two and the flow of the absorbent liquid are perfectly coordinated, which not only ensures the uniformity of the absorbent liquid spraying, but also uses the impact force of rotation to fully wet the surface of the absorbent liquid and the packing material 8. The partial contact improves the gas-liquid mass transfer efficiency and interacts with the stirring action of the stirring frame 28 below to prevent the absorbent liquid from accumulating and scaling on the surface of the packing 8, further ensuring the tail gas treatment effect and providing strong support for the stable and efficient operation of the device. After the absorbent liquid flows out from the outlet pipe 13, it directly impacts the impeller 21. The liquid flow drives the impeller 21 and the support frame 18 to rotate as a whole, realizing the rotating liquid distribution function. The support frame 18 adopts a lightweight and low inertia structure design. The hydraulic power provided by the circulating pump 11 is sufficient to stably drive the entire linkage structure to operate reliably.

[0039] The specific implementation process is as follows: The absorbent liquid is drawn into the inlet pipe 12 by the circulating pump 11 and discharged from the outlet pipe 13. The discharged absorbent liquid impacts the impeller 21 set below the outlet pipe 13. Due to the fluid momentum transfer, the impeller 21 is driven to rotate synchronously with the flow of absorbent liquid. The rotating impeller 21 drives the support frame 18 fixed on its opposite side. Under the stable support of the fixed frame 17 at the outlet end of the outlet pipe 13 and the limiting effect of the frame groove 19 in the middle of the support frame 18, the stable rotation is achieved. The stable rotating support frame 18 first sprays a portion of the absorbent liquid evenly onto the packing 8 placed in the middle of the screen frame 7 through several through holes 20 in its middle. The remaining absorbent liquid flows into the spray pipe 22 connected to it, and then is sprayed onto the surface of the remaining packing 8 through several spray holes 23 in the spray pipe 22. The support frame 18 and the spray pipe 22 rotate together, which can evenly distribute the absorbent liquid throughout the entire packing layer 8, achieving the effect of uniform distribution of absorbent liquid, effectively avoiding the impact of dead corners on the treatment effect, and thus significantly improving the performance of the treatment device.

[0040] Example 3

[0041] Please see Figure 1 - Figure 8 As shown, an automatic agitation and cleaning function has been added based on Embodiment 1;

[0042] Please refer to it again. Figure 1 - Figure 8As shown, a fixing ring 24 is fixed to the outer surface of the support frame 18. Several fixing plates 25 are fixed to the outer side of the fixing ring 24. Rotating rods 26 are rotatably connected to the other side of each fixing plate 25. A limit plate 27 is fixed to one side of each rotating rod 26. Several agitators 28 are fixed to the middle of each rotating rod 26. A gear 29 is fixed to the upper end of each rotating rod 26. Several gears 29 are meshed with a gear ring 30. The inner wall of the fixing ring 24 is fixed to the outer surface of the support frame 18. The cross-section of the fixing ring 24 is circular. Several fixing plates 25 are fixed to the middle of the outer side of the fixing ring 24 at their near ends. Several fixing plates 25 and several spray pipes 22 are staggered. Several fixing plates 25 are rotatably connected to the outer surface of several rotating rods 26 on their away sides. The upper end of each rotating rod 26 is fixed to the middle of each gear 29. The outer surface of each gear 29 is rotatably connected to the upper surface of each fixed plate 25. The outer surface of each limiting disc 27 is rotatably connected to the lower surface of each fixed plate 25. Several gears 29 mesh with a gear ring 30, the outer side of which is fixed to the upper inner wall of the processing tank 1. Several agitators 28 are fixed to the middle of each rotating rod 26. The cross-section of each agitator 28 is cross-shaped. Driven by the rotating rod 26, the rotating agitator 28 achieves a composite motion of synchronous revolution and rotation. This motion mode enables it to perform all-round, no-dead-angle agitation of the packing 8 placed on the screen frame 7. The agitator 28 revolves around the central axis of the fixed ring 24 with the rotating rod 26, covering the entire packing. The agitator 28 extends the transverse range of the packing layer 8, and its own rotation allows it to penetrate deep into the gaps between the packing layers 8, breaking up the dense layer formed by the packing layer 8. This prevents the absorbent from remaining on the surface of the packing layer 8 for too long, which could lead to scale buildup. During the agitation process, the agitator 28 does not damage the packing layer 8. It can gently scrape away the scale and impurities adhering to the surface of the packing layer 8, and also slightly rotate the packing layer 8, fully exposing the previously obscured surface of the packing layer 8 so that it can come into efficient contact with the absorbent sprayed by the spray pipe 22, further improving the gas-liquid mass transfer efficiency. In addition, the rotation of the agitator 28 can also accelerate the flow of the absorbent, promote the full reaction between the absorbent and the exhaust gas, reduce the local saturation of the absorbent, and extend the service life of the absorbent. Its operation requires no additional power, relying on the impact of the absorbent on the blades. The linkage mechanism driven by impeller 21 can realize automatic agitation. It works in coordination with the power supply system of control cabinet 14 to ensure stable operation of the equipment, completely eliminate the tedious operation of regular cleaning of packing 8 by staff, greatly reduce equipment maintenance costs, and further improve the ease of use and operational stability of the treatment device. After the absorbent flows out of the outlet pipe 13, it directly impacts the impeller 21. The flow of liquid drives the impeller 21 and support frame 18 to rotate as a whole, realizing the rotational liquid distribution function. The support frame 18, fixed ring 24, fixed plate 25, rotating rod 26 and agitator 28 all adopt a lightweight and low inertia structure design. The gear 29 and gear ring 30 are low-resistance meshing transmissions. The hydraulic power provided by the circulating pump 11 is sufficient to stably drive the entire linkage structure to operate reliably.

[0043] The specific implementation process is as follows: The absorbent liquid is drawn into the inlet pipe 12 by the circulating pump 11 and discharged from the outlet pipe 13. The discharged absorbent liquid impacts the impeller 21 located below the outlet pipe 13. Due to the transfer of fluid momentum, the impeller 21 rotates synchronously with the flow of absorbent liquid. The rotating impeller 21 drives its fixed support frame 18 to rotate together. The rotating support frame 18 then drives the fixed ring 24 fixed on its outer side to rotate. The rotating fixed ring 24 drives several fixed plates 25 fixed on its outer side to rotate synchronously. The rotating fixed plate 25 drives the rotating rod 26 rotatably connected to its other side to revolve around the central axis of the fixed ring 24. At the same time, under the stable support of the limiting plate 27, the rotating rod 26 drives the gear 29 to revolve synchronously. The revolving gear 29 meshes with the gear ring 30 fixed on the upper side of the treatment tank 1, and rotates during the revolution. The rotating gear 29 drives several agitators 28 fixed on the lower side of the rotating rod 26 through the rotating rod 26 fixed in the middle. The agitators 28 rotate while revolving with the rotating rod 26. The agitators 28 adopt a low-speed, gentle combined revolution and rotation motion, which does not violently stir the packing layer 8. Its main function is to slightly loosen and clean the impurities and scale attached to the surface of the packing 8. It will not damage the stable liquid film formed on the surface of the packing 8 and the normal gas-liquid mass transfer channel. While ensuring sufficient gas-liquid contact and maintaining a high mass transfer efficiency, it avoids clogging of the packing layer 8. This is different from the traditional static packing tower 8. It is an optimized design that takes into account both mass transfer effect and anti-clogging function, and does not violate the conventional design principles of absorption devices in this field. The rotating agitator 28 continuously agitates the packing 8, achieving automatic agitation and cleaning. It can automatically clean the scale generated on the packing 8, eliminating the need for regular manual cleaning by staff, thus effectively improving the ease of use of the treatment device.
