Description

Technical Field

[0001] This invention relates to the field of catalytic purification technology for organic waste gas, and in particular to a plasma catalytic purification system for organic waste gas. Background Technology

[0002] The plasma organic waste gas catalytic purification system is an air purification method that combines plasma and catalytic technologies, primarily used to treat organic waste gases. Its basic principle is to generate plasma (i.e., ionized gas) to excite molecules in the waste gas, and then, through a catalytic reaction, convert these organic compounds into harmless substances, ultimately achieving the purpose of purifying the waste gas.

[0003] Currently, since the organic waste gas to be catalytically purified usually contains solid particles, soot, fumes, or other solid components of gaseous pollutants, plasma organic waste gas catalytic purification systems separate these impurities from the gas flow through electric shock (such as electrostatic dust removal, airflow electric shock, etc.). The electrode wires may become carriers of these particles, causing them to adhere to the electrode surface. These adhered impurities affect the conductivity of the electrode wires, thereby weakening the electric field strength of the electrode wires and making the electric shock effect on the organic waste gas poor. Summary of the Invention

[0004] The purpose of this application is to provide a plasma catalytic purification system for organic waste gas, which solves the problems mentioned in the background art.

[0005] In a first aspect, the plasma organic waste gas catalytic purification system provided in this application adopts the following technical solution: it includes an organic waste gas treatment tank, and a medium baffle is provided on the inner side of the organic waste gas treatment tank. The medium baffle divides the inner side of the organic waste gas treatment tank into a discharge treatment zone and a catalytic purification zone. A fixing frame is provided on the inner side of the discharge treatment zone, and a high-voltage electrode is provided on the inner side of the fixing frame. A catalyst storage cylinder is provided on the inner side of the catalytic purification zone. An electrode cleaning assembly is provided on the inner side of the discharge treatment zone. The electrode cleaning assembly includes a dust cleaning assembly, a driving assembly, and a vibration assembly. The dust cleaning assembly is located above the high-voltage electrode, the driving assembly is located on one side of the dust cleaning assembly, and the vibration assembly is located on the dust cleaning assembly.

[0006] Preferably, the dust cleaning assembly includes connecting plates disposed on both sides of the upper surface of the fixed frame, with the two connecting plates positioned corresponding to each other. A dust removal fan is disposed between the two connecting plates, with pulleys at both ends of the dust removal fan. Guide grooves are formed on the connecting plates, and the two pulleys are slidably connected to the guide grooves on the two connecting plates respectively. Lower pressure plates are disposed at both ends of the dust removal fan, and the two lower pressure plates are respectively attached to the upper surface of the two connecting plates. The dust removal fan can clean the dust adhering to the surface of the high-voltage electrode by blowing it away. The pulleys and guide grooves guide and restrict the movement of the dust removal fan, while the lower pressure plates provide auxiliary stabilization for the movement of the dust removal fan.

[0007] Preferably, the drive assembly includes a sinking trough formed on the inner wall of the organic waste gas treatment tank and a servo motor mounted on the organic waste gas treatment tank. A turntable is rotatably mounted at the bottom inner side of the sinking trough, and the output end of the servo motor is connected to the turntable. A first movable plate is provided on one side of the turntable, and the first movable plate is connected to a pressure plate on the dust removal fan. A protrusion is provided on the turntable, and a sliding groove is formed on the side wall of the first movable plate opposite to the turntable. One end of the protrusion on the turntable is inserted into the sliding groove on the first movable plate. Limiting grooves are formed on the upper and lower inner walls of the sinking trough, and limiting plates are provided at both ends of the first movable plate. The two limiting plates are slidably mounted in the two limiting grooves respectively. By configuring the drive assembly, the dust removal fan moves horizontally back and forth along the guide trough, which increases the dust removal range of the high-voltage electrode surface, thereby reducing the number of dust removal fans required for high-voltage electrode surface dust removal and thus reducing the cost of high-voltage electrode surface dust removal.

[0008] Preferably, the vibration assembly includes receiving slots on both sides inside the dust collector fan and two top plates inserted into the dust collector fan. The two top plates pass through the two receiving slots respectively. A set of push plates is provided below each top plate, with multiple push plates in each set. Both sets of push plates are located on the upper surface of the fixed frame. A fixing spring is provided inside the receiving slot, and a first fixing ring is provided on the top plate. The first fixing ring is located inside the receiving slot, and one end of the fixing spring inside the receiving slot is connected to the fixing spring inside the receiving slot. One end of the top plate passes through the dust collector fan, and the end passing through the dust collector fan is located between two adjacent push plates. Two chamfers are provided at one end of the top plate, corresponding to two adjacent push plates. The vibration assembly causes the high-voltage electrode to vibrate at a frequency during air blowing. This not only loosens the firmly attached dust on the high-voltage electrode, making it easier to clean, but also vibrates and cleans areas on the high-voltage electrode that are difficult to clean by air blowing.

[0009] Secondly, the plasma organic waste gas catalytic purification system provided in this application adopts the following technical solution: the upper end face of the organic waste gas treatment tank is provided with a first cover plate and a second cover plate, the first cover plate and the second cover plate are respectively connected to the discharge treatment area and the catalytic purification area inside the organic waste gas treatment tank, and the first cover plate is provided with an impurity filter component.

[0010] Preferably, the impurity filtration assembly includes a connecting seat disposed on a first cover plate and an air duct disposed above the connecting seat. The connecting seat communicates with the discharge processing area. A filter plate is disposed inside the air duct. A slot is provided on the upper end face of the connecting seat. An insert block is provided at one end of the air duct. The insert block is inserted into the slot. Two placement openings are provided on the inner wall of the slot. A second movable plate is disposed inside the placement opening. Two grooves are provided on the insert block. One end of each of the two second movable plates is inserted into the two grooves on the insert block. The connecting seat has two sets of receiving ports, each located on one side of a placement port. Each set contains multiple receiving ports. The second movable plate has multiple push-pull rods, each passing through one set of receiving ports within the connecting seat. A helical spring is installed within each receiving port. A second fixing ring is attached to each push-pull rod, located within the receiving port through which the push-pull rod passes. One end of the helical spring within the receiving port is connected to the second fixing ring. A push-pull handle is located at the end of the push-pull rod away from the second movable plate, and the handle is attached to the outer wall of the connecting seat. The impurity filtration assembly filters impurities in the organic waste gas supplied to the organic waste gas treatment tank, reducing impurity accumulation inside the tank during treatment. Furthermore, the filter plates can be replaced by pulling and lifting, simplifying replacement and improving efficiency.

[0011] Preferably, the high-voltage electrode is spiral-shaped, a flow guide is provided at the top inner side of the first cover plate, a dust discharge port is provided at the bottom inner side of the limiting groove located at the bottom inner side of the settling tank, the dust discharge port is connected to the discharge treatment area, an L-shaped baffle is provided at the bottom inner side of the organic waste gas treatment tank, the L-shaped baffle is located below the dielectric baffle, and the L-shaped baffle and the dielectric baffle form a connecting passage between the discharge treatment area and the catalytic purification area, a heating rod is provided inside the catalyst storage cylinder, a fan pipe perforation is provided on the organic waste gas treatment tank, and a grounding electrode is provided on the lower end face of the fixing frame. The dust discharge port design prevents dust and impurities from accumulating at the bottom of the settling tank, thus avoiding interference with the horizontal reciprocating movement of the first moving plate along the limiting groove. Compared to traditional linear electrodes with a spiral high-voltage electrode, this design better prevents the accumulation of dust and impurities, reducing the difficulty of cleaning and maintenance. The L-shaped baffle design reduces the problem of dust from the bottom of the discharge treatment area drifting into the catalytic purification area and affecting the treatment of organic waste gas in the catalytic purification area. The catalyst storage cylinder is used to store the catalyst for catalytic organic waste gas, and the heating rod is used to heat the catalyst inside the catalyst storage cylinder, thereby improving the catalyst activity and catalytic effect.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By setting up the electrode cleaning component, the dust adhering to the surface of the high-voltage electrode is cleaned by horizontal back-and-forth air blowing and by frequency vibration of the high-voltage electrode. This can avoid the problem that the high-voltage electrode surface is covered with dust when it is electrocuting organic waste gas, which weakens the electric field strength of the high-voltage electrode and results in poor electrocuting effect of organic waste gas.

[0014] 2. By setting the drive components, the dust removal fan can move horizontally back and forth along the guide groove. This can increase the dust removal range of the dust removal fan on the surface of the high voltage electrode, thereby reducing the number of dust removal fans required for dust removal on the surface of the high voltage electrode, and thus reducing the cost of dust removal on the surface of the high voltage electrode.

[0015] 3. By setting up the vibration component, the high-voltage electrode vibrates at a frequency when blown by the wind. This not only loosens the dust that is firmly attached to the high-voltage electrode, making it easier to clean the dust attached to the high-voltage electrode, but also vibrates to clean the corners on the high-voltage electrode that are difficult to clean by the wind.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 This application will be described in further detail below.

[0031] Example 1: A plasma organic waste gas catalytic purification system includes an organic waste gas treatment tank 1. A medium baffle 14 is provided inside the organic waste gas treatment tank 1, dividing the inner side of the tank into a discharge treatment zone 2 and a catalytic purification zone 3. A fixing frame 4 is provided inside the discharge treatment zone 2, and a high-voltage electrode 5 is provided inside the fixing frame 4. A catalyst storage cylinder 9 is provided inside the catalytic purification zone 3. An electrode cleaning assembly 6 is provided inside the discharge treatment zone 2. The electrode cleaning assembly 6 includes a dust cleaning assembly 61, a driving assembly 62, and a vibration assembly 63. The dust cleaning assembly 61 is positioned above the high-voltage electrode 5, the driving assembly 62 is positioned to one side of the dust cleaning assembly 61, and the vibration assembly 63 is positioned on the dust cleaning assembly 61.

[0032] It should be noted that there are multiple high-voltage electrodes 5, which are arranged sequentially at equal intervals.

[0033] By setting the electrode cleaning component 6, the dust adhering to the surface of the high-voltage electrode 5 is cleaned by horizontal back-and-forth air blowing and by frequency vibration of the high-voltage electrode 5. This avoids the problem that the electric field strength of the high-voltage electrode 5 is weakened due to dust adhering to its surface when the high-voltage electrode 5 is used to electrocute organic waste gas, resulting in poor electrocuting effect.

[0034] The dust cleaning assembly 61 includes connecting plates 611 on both sides of the upper surface of the fixed frame 4. The two connecting plates 611 are positioned opposite each other, and a dust removal fan 612 is disposed between the two connecting plates 611. Pulleys 614 are provided at both ends of the dust removal fan 612. Guide grooves 613 are formed on the connecting plates 611, and the two pulleys 614 are slidably connected within the guide grooves 613 on the two connecting plates 611. Lower pressure plates 615 are provided at both ends of the dust removal fan 612, and the two lower pressure plates 615 are respectively attached to the upper surface of the two connecting plates 611. The dust removal fan 612 can clean the dust adhering to the surface of the high-voltage electrode 5 by blowing air. The pulleys 614 and guide grooves 613 guide and restrict the movement of the dust removal fan 612, and the lower pressure plates 615 provide auxiliary stabilization for the movement of the dust removal fan 612.

[0035] The drive assembly 62 includes a sinkhole 621 formed on the inner wall of the organic waste gas treatment tank 1 and a servo motor 622 mounted on the organic waste gas treatment tank 1. A turntable 623 is rotatably mounted on the bottom inner side of the sinkhole 621. The output end of the servo motor 622 is connected to the turntable 623. A first moving plate 625 is provided on one side of the turntable 623. The first moving plate 625 is connected to a pressure plate 615 on the dust removal fan 612. A protrusion 624 is provided on the turntable 623. A sliding groove 628 is formed on the side wall of the first moving plate 625 opposite to the turntable 623. One end of the protrusion 624 on the turntable 623 is inserted into the sliding groove 628 on the first moving plate 625. Limiting grooves 626 are formed on the upper and lower inner walls of the sinkhole 621. Limiting plates 627 are provided at both ends of the first moving plate 625. The two limiting plates 627 are slidably mounted in the two limiting grooves 626 respectively. By setting the drive component 62, the dust removal fan 612 moves horizontally back and forth along the guide groove 613. This can increase the dust removal range of the dust removal fan 612 on the surface of the high voltage electrode 5, thereby reducing the number of dust removal fans 612 required for dust removal on the surface of the high voltage electrode 5, and thus reducing the cost of dust removal on the surface of the high voltage electrode 5.

[0036] The vibration assembly 63 includes receiving slots 632 opened on both sides inside the dust removal fan 612 and two top plates 633 inserted on the dust removal fan 612. The two top plates 633 pass through the two receiving slots 632 respectively. A set of push plates 631 is provided below each top plate 633. There are multiple push plates 631 in each set. Both sets of push plates 631 are provided on the upper surface of the fixed frame 4. A fixing spring 634 is provided inside the receiving groove 632, and a first fixing ring 635 is provided on the top plate 633. The first fixing ring 635 is located inside the receiving groove 632. One end of the fixing spring 634 inside the receiving groove 632 is connected to the fixing spring 634 inside the receiving groove 632. One end of the top plate 633 passes through the dust removal fan 612 and is located between two adjacent push plates 631. Two chamfers 636 are formed at one end of the top plate 633, and the two chamfers 636 correspond to the two adjacent push plates 631. The vibration component 63 causes the high-voltage electrode 5 to vibrate at a frequency when blown by the air. This not only loosens the dust that is firmly attached to the high-voltage electrode 5, making it easier to clean the dust attached to the high-voltage electrode 5, but also vibrates to clean the dead corners on the high-voltage electrode 5 that are difficult to clean by air blowing.

[0037] The implementation principle of this application embodiment is as follows:

[0038] When it is necessary to clean the dust adhering to the surface of the high-voltage electrode 5, the servo motor 622 and the dust removal fan 612 are started. The servo motor 622 drives the turntable 623 and the protrusion 624 on the turntable 623 to rotate. During the rotation, the protrusion 624 pushes the first moving plate 625 to move horizontally back and forth along the limiting groove 626. The first moving plate 625 drives the dust removal fan 612 to move. The dust adhering to the high-voltage electrode 5 is blown away by the dust removal fan 612. During the movement of the dust removal fan 612, when the chamfer 636 of the top plate 633 of the dust removal fan 612 presses against the push plate 631 on the upper end face of the fixed frame 4, the push plate 631 makes the dust removal fan 612 move by pressing against the push plate 631 on the upper end face of the fixed frame 4 through the chamfer 636 on the top plate 633. The top plate 633 has an upward thrust. As the top plate 633 continues to move, it will move upward. During the upward movement, the first fixing ring 635 on the top plate 633 squeezes the fixing spring 634 inside the receiving groove 632 through which the top plate 633 passes. When the top plate 633 is misaligned with the push plate 631, the fixing spring 634 pushes the top plate 633 to strike the fixing frame 4. The fixing frame 4 vibrates due to the strike. The vibration of the fixing frame 4 causes the high-voltage electrode 5 set on it to vibrate. During the vibration, the high-voltage electrode 5 can loosen and shake off the dust and impurities attached to it. In the above manner, the fixing frame 4 vibrates at a frequency, thereby vibrating and cleaning the dust on the high-voltage electrode 5.

[0039] Example 2: A plasma organic waste gas catalytic purification system, wherein the upper end face of the organic waste gas treatment tank 1 is provided with a first cover plate 11 and a second cover plate 12, the first cover plate 11 and the second cover plate 12 are respectively connected to the discharge treatment zone 2 and the catalytic purification zone 3 inside the organic waste gas treatment tank 1, and an impurity filter component 7 is provided on the first cover plate 11.

[0040] The impurity filtration assembly 7 includes a connecting seat 71 disposed on the first cover plate 11 and an air duct 72 disposed above the connecting seat 71. The connecting seat 71 communicates with the discharge processing area 2. A filter plate 713 is disposed inside the air duct 72. A slot 73 is opened on the upper end face of the connecting seat 71. An insert block 74 is disposed at one end of the air duct 72. The insert block 74 is inserted into the slot 73. Two placement openings 75 are opened on the inner wall of the slot 73. A second movable plate 77 is disposed inside the placement opening 75. Two grooves 76 are opened on the insert block 74. One end of each of the two second movable plates 77 is inserted into the two grooves 76 on the insert block 74. The connecting seat 71 has two sets of receiving ports 78, which are located on one side of the two placement ports 75. Each set of receiving ports 78 has multiple ports. The second movable plate 77 is provided with multiple push-pull rods 79, which pass through one set of receiving ports 78 in the connecting seat 71. A helical spring 710 is provided in the receiving port 78. A second fixing ring 711 is provided on the push-pull rod 79. The second fixing ring 711 is located in the receiving port 78 through which the push-pull rod 79 passes. One end of the helical spring 710 in the receiving port 78 is connected to the second fixing ring 711 in the receiving port 78. A push-pull handle 712 is provided at the end of the push-pull rod 79 away from the second movable plate 77. The push-pull handle 712 is attached to the outer wall of the connecting seat 71. The impurity filtration component 7 can filter impurities in the organic waste gas delivered to the inside of the organic waste gas treatment tank 1, thereby reducing the accumulation of impurities inside the organic waste gas treatment tank 1 during the treatment of organic waste gas. Moreover, the filter plate 713 can be replaced by pulling and lifting, which reduces the difficulty and complexity of replacing the filter plate 713 and effectively improves the replacement efficiency of the filter plate 713.

[0041] The high-voltage electrode 5 is spiral-shaped. A flow guide shroud 110 is provided at the top inner side of the first cover plate 11. A dust discharge port 8 is provided at the bottom inner side of the limiting groove 626 located at the bottom inner side of the sinking trough 621. The dust discharge port 8 is connected to the discharge treatment area 2. An L-shaped baffle 10 is provided at the bottom inner side of the organic waste gas treatment tank 1. The L-shaped baffle 10 is located below the dielectric baffle 14. The L-shaped baffle 10 and the dielectric baffle 14 form a connecting passage between the discharge treatment area 2 and the catalytic purification area 3. A heating rod 91 is provided inside the catalyst storage cylinder 9. A fan pipe perforation 13 is provided on the organic waste gas treatment tank 1. A grounding electrode 15 is provided on the lower end face of the fixing frame 4.

[0042] It should be noted that the catalyst storage cylinder 9 is made of honeycomb ceramic material, and the surface of the catalyst storage cylinder 9 is coated with a ternary oxide coating.

[0043] The dust outlet 8 prevents dust and impurities from accumulating at the bottom of the sink trough 621, thus avoiding interference with the horizontal reciprocating movement of the first moving plate 625 along the limiting groove 626. Compared to the traditional spiral high-voltage electrode 5 with a linear electrode, this design better prevents the accumulation of dust and impurities, reducing the difficulty of cleaning and maintenance. The L-shaped baffle 10 reduces the problem of dust drifting into the catalytic purification zone 3 from the bottom of the discharge treatment zone 2 and affecting the treatment of organic waste gas in the catalytic purification zone 3. The catalyst storage cylinder 9 is used to store the catalyst for catalytic organic waste gas, and the heating rod 91 is used to heat the catalyst inside the catalyst storage cylinder 9, thereby improving the activity and catalytic effect of the catalyst.

[0044] The implementation principle of this application embodiment is as follows:

[0045] When the filter plate 713 inside the duct 72 becomes heavily clogged, it needs to be replaced. When the filter plate 713 needs to be replaced, the second moving plate 77 is pulled by the push-pull handle 712. During the pulling process, the push-pull rod 79 connected to the push-pull handle 712 moves. During the movement, the second fixing ring 711 on the push-pull rod 79 compresses the spiral spring 710 in the receiving port 78 through which the push-pull rod 79 passes. When the second moving plate 77 inserted inside the groove 76 is pulled out and stored inside the placement port 75, the duct 72 is lifted and taken out. Then, the duct 72 with the new filter plate 713 is connected to the connecting seat 71 in the above manner.

[0046] Working principle of this invention:

[0047] When it is necessary to clean the dust adhering to the surface of the high-voltage electrode 5, the servo motor 622 and the dust removal fan 612 are started. The servo motor 622 drives the turntable 623 and the protrusion 624 on the turntable 623 to rotate. During the rotation, the protrusion 624 pushes the first moving plate 625 to move horizontally back and forth along the limiting groove 626. The first moving plate 625 drives the dust removal fan 612 to move. The dust adhering to the high-voltage electrode 5 is blown away by the dust removal fan 612 as it moves. When the chamfer 636 of the top plate 633 on the dust collector fan 612 presses against the push plate 631 on the upper end face of the fixed frame 4, the push plate 631 exerts an upward thrust on the top plate 633 through the chamfer 636. As the top plate 633 continues to move, it will move upward. During the upward movement, the first fixing ring 635 on the top plate 633 compresses the fixing spring 634 inside the receiving groove 632 through which the top plate 633 passes. When the top plate 633 and the push plate 631 are misaligned, the fixing spring 634 pushes the top plate 633. Plate 633 strikes the mounting bracket 4, causing the bracket 4 to vibrate. This vibration causes the high-voltage electrode 5 mounted on it to vibrate, loosening and dislodging dust and impurities adhering to the electrode 5. The mounting bracket 4 vibrates at a specific frequency in this manner, thus cleaning the dust from the high-voltage electrode 5. When the filter plate 713 inside the duct 72 becomes heavily clogged, it needs to be replaced. To replace the filter plate 713, the second movable part is pulled using the push-pull handle 712. During the pulling process, the push-pull rod 79 connected to the push-pull handle 712 moves. During the movement of the push-pull rod 79, the second fixing ring 711 on the push-pull rod 79 compresses the helical spring 710 in the receiving port 78 through which the push-pull rod 79 passes. When the second moving plate 77 inserted in the groove 76 is pulled out and stored in the placement port 75, the air duct 72 is lifted and taken out. Then, the air duct 72 with the new filter plate 713 is connected to the connecting seat 71 in the above manner.
