Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a device for treating organic waste gas. Background Technology

[0002] With the continuous advancement of industrialization, the amount of organic waste gas emitted during industrial production is constantly increasing. If it is discharged directly without effective purification treatment, it will have a significant impact on the atmospheric environment, ecological security and human health. At present, organic waste gas treatment devices have been widely used in chemical, coating and printing industries, but there are still many problems in the actual use of existing equipment.

[0003] Traditional organic waste gas treatment devices have short residence times and simple flow paths inside the tank during use, making it difficult to form sufficient turbulence and circulation. This results in short contact time or small contact area between the adsorption and purification structures inside the waste gas tank, leading to incomplete capture of particulate matter and organic pollutants in the waste gas. Consequently, the overall purification efficiency of the device is low and the treatment effect is unstable. Summary of the Invention

[0004] This invention intermittently discharges waste gas through two sets of exhaust ports via a collection tank, causing the waste gas to be retained inside the collection tank during the sealing stage. During the retention process, the waste gas is circulated back through the return pipe, which greatly increases the residence time of the waste gas inside the collection tank and improves the adequacy of treatment. At the same time, the repeated flow of waste gas inside the collection tank prolongs the contact time between the waste gas and the baffle plate, allowing the baffle plate to more effectively adsorb and intercept impurities in the waste gas.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an organic waste gas treatment device, comprising a collection tank, an air inlet connected to one side of the collection tank, two sets of exhaust ports connected to the upper end of the collection tank, a partition installed inside the collection tank, a rotating shaft rotatable inside the collection tank, multiple sets of baffles fixedly connected to the outer side of the rotating shaft, two sets of gears B driven by the rotating shaft rotatable at the upper end of the collection tank, two sets of guide tubes installed on the upper end of the inner wall of the collection tank, pistons driven by the two sets of gears B sliding inside the two sets of guide tubes, two sets of guide rails installed inside the partition, and sealing plugs driven by the pistons sliding inside the two sets of guide rails;

[0006] Both sets of guide tubes are connected to a liquid storage tank on one side. A spray pipe is installed at the lower end of the partition. Multiple spray nozzles are arranged on the outside of the spray pipe. One end of both sets of liquid storage tanks is connected to the spray pipe.

[0007] Preferably, a motor is installed at the upper end of the collection tank, the output end of the motor is connected to the rotating shaft, and a gear A is provided at the upper end of the collection tank. The gear A is fixedly connected to the outside of the rotating shaft, and the gear A meshes with two sets of gears B.

[0008] Preferably, one end of each of the two sets of gears B is connected to a reciprocating lead screw, the other end of each of the two sets of reciprocating lead screws passes through the collection tank and extends into the interior of the two sets of guide tubes, and each of the two sets of reciprocating lead screws is connected to two sets of piston ball nut pairs.

[0009] Preferably, two sets of push rods are fixedly connected to the upper ends of the two sets of sealing plugs, and two sets of cleaning blocks are installed at the lower ends of the two sets of guide tubes. The two sets of push rods extend into the interior of the guide tubes through the two sets of cleaning blocks.

[0010] Preferably, one end of each of the two sets of sealing plugs is fixedly connected to a spring, the other end of each of the two sets of springs is connected to a guide rail, and a return pipe is connected to one side of the collection tank.

[0011] Preferably, one side of each of the two sets of guide pipes is connected to a connecting pipe A, and one end of each of the two sets of connecting pipes A passes through the collection tank and extends to the outside of the collection tank to connect with the two sets of liquid storage tanks.

[0012] Preferably, one end of each of the two sets of liquid storage tanks is connected to a connecting pipe B, and the other end of each of the two sets of connecting pipes B passes through the collection tank and the baffle and is connected to the spray pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By intermittently discharging the exhaust gas through two sets of exhaust ports through the collection tank, the exhaust gas is retained inside the collection tank during the sealing stage. During the retention process, the exhaust gas is circulated back through the return pipe, which greatly increases the residence time of the exhaust gas inside the collection tank and improves the adequacy of treatment. At the same time, the exhaust gas flows repeatedly inside the collection tank, prolonging the contact time between the exhaust gas and the baffle plate, so that the baffle plate can more effectively adsorb and intercept impurities in the exhaust gas.

[0015] 2. When the inside of the collection tank is in a closed environment, water is sprayed through multiple sets of nozzles to fully mix the water mist with the exhaust gas and wet the impurities in the exhaust gas, thereby better capturing particulate matter, soluble impurities and some organic pollutants in the exhaust gas. At the same time, spraying water in a sealed state prevents the gas from avoiding contact with the water source, prolongs the gas-liquid contact time and improves the efficiency of dust reduction and impurity removal.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 5 This invention provides an organic waste gas treatment device, including a collection tank 1, an air inlet 2 connected to one side of the collection tank 1, two sets of exhaust ports 3 connected to the upper end of the collection tank 1, a partition 11 installed inside the collection tank 1, a rotating shaft 5 rotatably installed inside the collection tank 1, multiple sets of baffles 21 fixedly connected to the outside of the rotating shaft 5, two sets of gears B7 driven by the rotating shaft 5 rotatably installed at the upper end of the collection tank 1, two sets of guide tubes 9 installed at the upper end of the inner wall of the collection tank 1, pistons 10 driven by the two sets of gears B7 sliding inside the two sets of guide tubes 9, two sets of guide rails 13 installed inside the partition 11, and sealing plugs 12 driven by the pistons 10 sliding inside the two sets of guide rails 13.

[0024] Both sets of guide pipes 9 are connected to a liquid storage tank 18 on one side. A nozzle 20 is installed at the lower end of the partition plate 11. Multiple nozzles are provided on the outside of the nozzle 20. One end of both sets of liquid storage tanks 18 is connected to the nozzle 20.

[0025] In an optional embodiment, a motor 4 is installed on the upper end of the collection tank 1, the output end of the motor 4 is connected to the rotating shaft 5, and a gear A6 is provided on the upper end of the collection tank 1. The gear A6 is fixedly connected to the outside of the rotating shaft 5, and the gear A6 meshes with two sets of gears B7.

[0026] When using the device, the operator introduces the exhaust gas into the collection tank 1 through the air inlet 2. After the exhaust gas enters the collection tank 1, the operator starts the motor 4. After the motor 4 starts, the motor 4 will drive the rotating shaft 5 to rotate inside the collection tank 1. When the rotating shaft 5 rotates, the rotating shaft 5 will simultaneously drive multiple sets of baffles 21 to rotate inside the collection tank 1. When the multiple sets of baffles 21 rotate, they will cause the exhaust gas to form a vortex inside the collection tank 1. As the multiple sets of baffles 21 gradually rotate, they will come into contact with impurities in the exhaust gas, thereby attaching the impurities in the exhaust gas to the surface of the baffles 21. When the exhaust gas forms a vortex inside the collection tank 1, large pieces of impurities in the exhaust gas will gradually settle towards the bottom of the collection tank 1.

[0027] When the rotating shaft 5 rotates, the rotating shaft 5 will synchronously drive the gear A6 to rotate. When the gear A6 rotates, the gear A6 will synchronously drive the two sets of gears B7 to rotate.

[0028] In an optional embodiment, one end of each of the two sets of gears B7 is connected to a reciprocating screw 8, and the other end of each of the two sets of reciprocating screws 8 passes through the collection tank 1 and extends into the interior of the two sets of guide tubes 9. Both sets of reciprocating screws 8 are connected to the ball nut pairs of the two sets of pistons 10.

[0029] The guide tube 9 has a guide groove inside, and the piston 10 is slidably connected to the guide groove. As described above, when the two sets of gears B7 rotate, the two sets of gears B7 will synchronously drive the two sets of reciprocating screws 8 to rotate inside the guide tube 9. When the reciprocating screws 8 rotate, the reciprocating screws 8 will drive the piston 10 to reciprocate along the guide groove inside the guide tube 9.

[0030] In an optional embodiment, two sets of push rods 15 are fixedly connected to the upper ends of the two sets of sealing plugs 12, and two sets of cleaning blocks 16 are installed at the lower ends of the two sets of guide tubes 9. The two sets of push rods 15 extend into the interior of the guide tubes 9 through the two sets of cleaning blocks 16.

[0031] When the piston 10 moves to the lower end inside the guide tube 9, the piston 10 will contact the two sets of push rods 15. As the piston 10 continues to descend, the piston 10 will squeeze the two sets of push rods 15 to move synchronously.

[0032] In an optional embodiment, one end of each of the two sets of sealing plugs 12 is fixedly connected to a spring 14, and the other end of each of the two sets of springs 14 is connected to a guide rail 13. A return pipe 22 is connected to one side of the collection tank 1.

[0033] Initially, because the partition 11 is sealed by two sets of sealing plugs 12, exhaust gas cannot enter the upper part through the partition 11 and be discharged through the two sets of exhaust ports 3. As mentioned above, when the two sets of push rods 15 move downward, they will simultaneously push the sealing plugs 12 down along the guide rail 13. When the sealing plugs 12 descend, they will simultaneously squeeze the spring 14. After the two sets of sealing plugs 12 descend along the guide rail 13, they no longer seal the partition 11, and exhaust gas will enter the upper part of the partition 11 through the partition 11 and be transported to the next filtration stage through the two sets of exhaust ports 3. As the reciprocating screw 8 continues to drive the piston 10 to move, the piston 10 will gradually disengage from the two sets of push rods 15. When the squeezing force of the piston 10 on the two sets of push rods 15 disappears, the sealing plugs 12 will rise and reset along the guide rail 13 by the force of the spring 14. After the sealing plugs 12 reset, the seal... The seal 12 will seal the partition 11 again. When the partition 11 is sealed, the exhaust gas inside the collection tank 1 will be retained and continuously refluxed inside the collection tank 1 through the return pipe 22. When the device is used, the exhaust gas will be discharged intermittently, thereby increasing the residence time of the exhaust gas inside the collection tank 1 and increasing the contact time between the baffle 21 and the exhaust gas. This allows the multiple baffles 21 to better adhere the impurities in the exhaust gas to the surface. Thus, the exhaust gas is discharged intermittently through the two exhaust ports 3 of the collection tank 1, so that the exhaust gas is retained inside the collection tank 1 during the sealing stage. During the retention process, the exhaust gas circulates back through the return pipe 22, which greatly increases the residence time of the exhaust gas inside the collection tank 1 and improves the treatment adequacy. At the same time, the exhaust gas flows repeatedly inside the collection tank 1, prolonging the contact time between the exhaust gas and the baffle 21, so that the baffle 21 can more fully adsorb and intercept the impurities in the exhaust gas.

[0034] When the two sets of push rods 15 rise and reset, the two sets of push rods 15 will re-enter the guide tube 9 through the two sets of cleaning blocks 16. When the two sets of push rods 15 pass through the cleaning blocks 16, the cleaning blocks 16 will clean the dust and impurities on the outside of the push rods 15 to prevent dust from entering the guide tube 9 and affecting the reciprocating screw 8.

[0035] In an optional embodiment, each of the two sets of guide pipes 9 is connected to a connecting pipe A17 on one side, and one end of each of the two sets of connecting pipes A17 passes through the collection tank 1 and extends to the outside of the collection tank 1 to connect with the two sets of liquid storage tanks 18.

[0036] Both sets of liquid storage tanks 18 contain water. As mentioned above, when the piston 10 is driven to rise and reset by the reciprocating screw 8, as the piston 10 rises, the piston 10 will squeeze the gas into the connecting pipe A17. After the gas enters the connecting pipe A17, the connecting pipe A17 will transport the gas to the liquid storage tank 18.

[0037] In an optional embodiment, one end of each of the two sets of liquid storage tanks 18 is connected to a connecting pipe B19, and the other end of each of the two sets of connecting pipes B19 passes through the collection tank 1 and the partition 11 and is connected to the spray pipe 20.

[0038] When the gas enters the storage tank 18, it forces a small amount of water into the connecting pipe B19. Once inside the connecting pipe B19, the water is transported to the nozzle 20 and sprayed outwards through multiple nozzles. At this time, the piston 10 is located at the upper end of the guide pipe 9, and the reset of the two sets of sealing plugs 12 seals the inside of the collection tank 1. Therefore, the water is sprayed outwards in a closed state inside the partition 11, allowing the water to fully contact the impurities in the exhaust gas, further reducing the impurities in the exhaust gas. Thus, when the inside of the collection tank 1 is in a closed environment, water is sprayed through multiple nozzles, allowing the water mist to fully mix with the exhaust gas and wetting the impurities in the exhaust gas. This better captures particulate matter, soluble impurities, and some organic pollutants in the exhaust gas. At the same time, spraying water in a sealed state prevents the gas from avoiding contact with the water source, prolonging the gas-liquid contact time and improving dust reduction and impurity removal efficiency.

[0039] Working principle: When using the device, the operator introduces the exhaust gas into the collection tank 1 through the air inlet 2. After the exhaust gas enters the collection tank 1, the operator starts the motor 4. After the motor 4 starts, it drives the rotating shaft 5 to rotate inside the collection tank 1. When the rotating shaft 5 rotates, it will simultaneously drive multiple sets of baffles 21 to rotate inside the collection tank 1. When the multiple sets of baffles 21 rotate, they will cause the exhaust gas to form a vortex inside the collection tank 1. As the multiple sets of baffles 21 rotate, they will come into contact with impurities in the exhaust gas, thereby adhering the impurities in the exhaust gas to the surface of the baffles 21. When the exhaust gas forms a vortex inside the collection tank 1, large impurities in the exhaust gas will gradually settle to the bottom of the collection tank 1.

[0040] When the rotating shaft 5 rotates, the rotating shaft 5 will synchronously drive the gear A6 to rotate. When the gear A6 rotates, the gear A6 will synchronously drive the two sets of gears B7 to rotate. When the two sets of gears B7 rotate, the two sets of gears B7 will synchronously drive the two sets of reciprocating screws 8 to rotate inside the guide tube 9. When the reciprocating screws 8 rotate, the reciprocating screws 8 will drive the piston 10 to reciprocate along the guide groove inside the guide tube 9. When the piston 10 moves to the lower end inside the guide tube 9, the piston 10 will contact the two sets of push rods 15. Then, as the piston 10 continues to descend, the piston 10 will squeeze the two sets of push rods 15 to move synchronously.

[0041] When the two sets of push rods 15 move downwards, they simultaneously push the sealing plugs 12 down along the guide rail 13. As the sealing plugs 12 descend, they simultaneously compress the spring 14. After the two sets of sealing plugs 12 descend along the guide rail 13, they no longer seal the partition 11. Therefore, exhaust gas passes through the partition 11 and enters its upper part, and is then transported to the next filtration stage through the two exhaust ports 3. As the reciprocating screw 8 continues to drive the piston 10, it continues to move. Piston 10 will gradually disengage from the two sets of push rods 15. When the squeezing force of piston 10 on the two sets of push rods 15 disappears, the sealing plug 12 will rise and reset along the guide rail 13 by the force of spring 14. After the sealing plug 12 resets, it will seal the partition 11 again. When the partition 11 is sealed, the exhaust gas inside the collection tank 1 will be retained and continuously flow back inside the collection tank 1 through the return pipe 22. Thus, when the device is used, the exhaust gas will be intermittently discharged to the outside.

[0042] When piston 10 is driven to rise and reset by reciprocating screw 8, as piston 10 rises, piston 10 will squeeze gas into the connecting pipe A17. After the gas enters the connecting pipe A17, the connecting pipe A17 will transport the gas to the liquid storage tank 18. After the gas enters the liquid storage tank 18, the gas will squeeze a small amount of water into the connecting pipe B19. After the water enters the connecting pipe B19, the connecting pipe B19 will transport the water to the nozzle 20 and spray it outward through multiple nozzles. At this time, piston 10 is located at the upper end of the guide pipe 9, and the reset of the two sets of sealing plugs 12 will seal the inside of the collection tank 1. Therefore, the water is sprayed outward in a closed state inside the partition 11.
