Description

Technical Field

[0001] This invention relates to the field of activated carbon production technology, and in particular to a purification device for activated carbon production. Background Technology

[0002] The production of activated carbon generates organic waste gas in a high-temperature environment, which often needs to be treated before being discharged.

[0003] Chinese patent CN119258677A discloses a purification device for activated carbon production, comprising: a purification box, a first baffle, a second baffle, a filtration mechanism, a spraying mechanism, a water collection tank, and a drying mechanism. The purification box has air inlets and outlets on both sides, and a water outlet at the bottom front end. The upper end of the first baffle is fixedly connected to the upper inner surface of the purification box, and the lower end of the second baffle is fixedly connected to the lower inner surface of the purification box. Due to the separation of the purification box by the first and second baffles, the interior of the purification box is divided into three chambers: a filtration chamber, a neutralization chamber, and a drying chamber. The water collection tank is fixedly installed at the bottom of the neutralization chamber.

[0004] After the exhaust gas is treated with sprayed liquid, solid particles will still be dispersed with the airflow and often need to be filtered. However, during continuous air intake treatment, if the airflow is too fast, the exhaust gas may not be completely treated by the sprayed liquid, and if the airflow is too slow, solid particles may block the gas flow at the filter screen. Summary of the Invention

[0005] Based on the technical problems in the background art, the present invention proposes a purification device for activated carbon production.

[0006] This invention proposes a purification device for activated carbon production, comprising a purification channel, an air inlet pipe, an exhaust pipe, and a drain pipe. Both ends of the purification channel are connected to the air inlet pipe via connecting pipes. The exhaust pipe and the drain pipe are located in the middle of the purification channel. Two sets of nozzles are installed inside the purification channel. A filter plate is installed between the nozzles and the exhaust pipe inside the purification channel. One end of the filter plate is fixed to a rotating shaft, and one end of the rotating shaft is rotatably connected to the purification channel via a torsion spring. Under normal conditions, the end of the filter plate away from the rotating shaft is in contact with the inner wall of the purification channel. When the air pressure in the chamber facing the nozzle increases and pushes the filter plate to deflect, the end of the filter plate away from the rotating shaft gradually moves away from the inner wall of the purification channel.

[0007] Preferably, the purification channel is provided with a left channel and a right channel, and a lower channel connects the left channel and the right channel. Both the left channel and the right channel are configured as arc-shaped structures, and the ends of the left channel and the right channel near the lower channel extend vertically downwards. The lower channel is configured as an arc-shaped structure that arches downwards in the middle.

[0008] Preferably, the two sets of nozzles are located at the ends of the left and right channels near the lower channel, respectively, and the two filter plates are respectively set at both ends of the lower channel, with the rotating shaft installed at the top of the lower channel. Under normal conditions, the filter plates are tilted downwards away from the middle of the lower channel.

[0009] Preferably, a collision element is horizontally arranged at the middle position of the lower channel, and the collision element is located between the two filter plates.

[0010] Preferably, two crossbars are fixed at positions corresponding to the collision component on the side wall of the purification channel. A sliding groove is provided on the side of the collision component to slide in contact with the outer wall of the crossbar. Limiting blocks are fixed on both sides of the crossbar on the collision component, and fan blades are fixed at both ends of the bottom of the collision component.

[0011] Preferably, both the left and right channels are provided with movable baffles that move radially in the left and right channels. The baffles are located on the side of the nozzle near the connecting pipe, and one end of the baffle is connected to an electric telescopic rod. The outer wall of the baffle slides in contact with the side of the purification channel.

[0012] Preferably, the baffle has multiple air holes on its side, and a storage box is installed outside the purification channel at a position corresponding to the baffle.

[0013] Preferably, a collision plate is provided between the filter plate and the baffle, and slide rails are installed on the inner walls of both sides of the purification channel at positions corresponding to the collision plate. A slider is fixed at the position corresponding to the collision plate and the slide rail, and the slider slides within the slide rail.

[0014] Preferably, the slide rail is inclined downward toward the middle of the lower channel, and the slide rail is configured as an arc-shaped structure with the middle position arching outward.

[0015] Preferably, an elastic rope is connected between the end of the collision plate near the baffle and the end of the baffle facing the nozzle, and the sliders at both ends of the collision plate are at the bottom of the slide rail, so that the collision plate is kept horizontal.

[0016] The beneficial effects of this invention are as follows: In this invention, the system can simultaneously address the accumulation of solid particles or the increase in air pressure to ensure the effectiveness and continuity of the continuous purification treatment of exhaust gas. It can prevent the filter plate from being blocked for a long time, thus avoiding the impact on the efficiency of continuous air intake purification treatment. Furthermore, by concentrating the solid particles before discharging them with the liquid, it avoids the problem of some solid particles being dispersed with the airflow when discharged directly.

[0017] In this invention, when the air pressure is too high due to filter plate blockage at the nozzle position, or when the filter plate deflects due to excessive accumulation of solid particles, the baffle can be extended to prevent the airflow from flowing directly out of the gap, thereby ensuring the completeness and effectiveness of the exhaust gas purification treatment during the process of clearing the airflow channel; and the baffle and the collision plate work together to effectively improve the purification effect of the exhaust gas.

Detailed Implementation

[0020] Example 1: Refer to Figures 1-8A purification device for activated carbon production includes a purification channel 1, an air inlet pipe 3, an exhaust pipe 7, and a liquid drain pipe 8. Both ends of the purification channel 1 are connected to the air inlet pipe 3 by connecting pipes 2. The exhaust pipe 7 and the liquid drain pipe 8 are located in the middle of the purification channel 1. Two sets of nozzles 4 are installed inside the purification channel 1, positioned between the connecting pipes 2 and the exhaust pipe 7. Each nozzle 4 is connected to a liquid injection pipe 5. A filter plate 6 is installed inside the purification channel 1 between the nozzles 4 and the exhaust pipe 7. A rotating shaft 9 is fixed to one end of the filter plate 6. One end of the filter plate 6 is rotatably connected to the purification channel 1 via a torsion spring. An installation groove is provided inside the purification channel 1 at a position corresponding to the rotating shaft 9. The rotating shaft 9 rotates within the installation groove to ensure a relatively tight and sealed fit. The opening of the installation groove allows the filter plate 6 to move within a certain angle range. Under normal conditions, the end of the filter plate 6 away from the rotating shaft 9 is in contact with the inner wall of the purification channel 1. When the air pressure in the chamber facing the nozzle 4 increases, causing the filter plate 6 to deflect, the end of the filter plate 6 away from the rotating shaft 9 gradually moves away from the purification channel 1. The waste gas to be treated enters the purification channel 1 from the inlet pipe 3 through two connecting pipes 2 at both ends. The waste gas is then sprayed with treatment liquid through the nozzle 4 to purify the waste gas. After contacting the treatment liquid, the waste gas passes through the filter plate 6 and is discharged from the middle of the purification channel 1. Wastewater is led out from the drain pipe 8 and dispersed into the purification channel 1 to avoid clogging of the filter plate 6, which would prevent the continuous treatment from being affected by the complete inability to enter the air. When one of the filter plates 6 becomes clogged due to excessive solid particles on the side close to the nozzle 4, the filter plate 6 will be deflected towards the purification channel 1, so that the end of the filter plate 6 away from the rotating shaft 9 gradually moves away from the inner wall of the purification channel 1. This allows the solid particles on the filter plate 6 to flow out from the gap and be discharged with the liquid. On the one hand, this avoids the filter plate 6 from being clogged for a long time, which would affect the efficiency of continuous air intake purification. On the other hand, by concentrating the solid particles before they are discharged with the liquid, it avoids some solid particles being dispersed with the airflow when discharged directly, thereby improving the effectiveness and treatment effect of continuous treatment of waste gas from activated carbon production.

[0021] In this invention, the purification channel 1 is provided with a left channel 101 and a right channel 102, and a lower channel 103 connects the left channel 101 and the right channel 102. The ends of the left channel 101 and the right channel 102 away from the lower channel 103 are connected to the connecting pipe 2. The exhaust pipe 7 is located at the middle position of the top of the lower channel 103, and the drain pipe 8 is located at the middle position of the bottom of the lower channel 103. Both the left channel 101 and the right channel 102 are configured with an arc-shaped structure. The ends of channels 102 near the lower channel 103 extend vertically downwards. The lower channel 103 is designed as an arc-shaped structure that arches downwards in the middle. The two sets of nozzles 4 are located at the ends of the left channel 101 and the right channel 102 near the lower channel 103, respectively. Through the arc-shaped bending structure of the left channel 101, the lower channel 103, and the right channel 102, the airflow is deflected and its impact force is reduced around the nozzle 4, preventing the incoming airflow from being too fast and not fully contacting the treatment liquid, thus ensuring... To ensure effective gas purification, two filter plates 6 are positioned at both ends of the lower channel 103, with the rotating shaft 9 installed at the top of the lower channel 103. Under normal conditions, the filter plates 6 are tilted downwards away from the center of the lower channel 103, and the end of the filter plate 6 away from the rotating shaft 9 is in contact with the inner wall of the purification channel 1. After the gas comes into contact with the treatment liquid sprayed from the nozzle 4, it passes through the filter plates 6 and flows out. The remaining solid particles concentrate at the top of the filter plates 6. Due to the tilted top surface of the filter plates 6 under normal conditions, the solid particles are mainly concentrated on the side of the filter plates 6 away from the rotating shaft 9, thus ensuring unobstructed flow in most areas of the filter plates 6. Furthermore, the concentration of solid particles allows the accumulation of a certain amount of fixed particles to open the gap in the filter plates 6 away from the rotating shaft 9 under gravity, causing the concentrated solid particles to clump together and flow out with the liquid. This allows for simultaneous clearing operations to address the accumulation of solid particles or increases in gas pressure, ensuring the effectiveness and continuity of continuous waste gas purification.

[0022] In this invention, a collision element 10 is horizontally arranged in the middle of the lower channel 103. The collision element 10 is located between two filter plates 6. When the filter plate 6 deflects due to the weight of accumulated solid particles or due to the blockage of the air intake direction causing an increase in air pressure, the filter plate 6 will collide with the end of the collision element 10 after deflecting to a certain extent, so as to improve the effect of clearing solid particles above the filter plate 6 when the filter plate 6 rotates to open the notch.

[0023] In this invention, two crossbars 11 are fixed at positions corresponding to the collision member 10 on the side wall of the purification channel 1. A sliding groove is provided on the side of the collision member 10 to slide in contact with the outer wall of the crossbars 11. Limiting blocks 111 are fixed on both sides of the crossbars 11, allowing the collision member 10 to remain horizontal and move horizontally via the two crossbars 11. Symmetrically arranged fan blades 12 are fixed at both ends of the bottom of the collision member 10, causing the collision member 10 to move according to the difference in airflow through the filter plates 6 at both ends. Under normal conditions, the airflow intensity at both ends is almost the same. Under the combined action of the blowing force in the middle and the suction force of the exhaust pipe 7 in the middle position, the collision member 10 is pushed to the middle position by the wind force at both ends. When the filter plate 6 on one side is blocked, the airflow intensity through the filter plate 6 will decrease, while the blowing force on the other end of the collision member 10 remains unchanged. Thus, under the difference in airflow intensity through the filter plate 6, the collision member 10 will move towards the blocked end of the filter plate 6, so that the filter plate 6 will collide with the actively moving collision member 10 to clear the blockage when it deflects by a small amount. Furthermore, when the filter plate 6 continues to deflect, it can also push the collision member 10 to move, thus ensuring the effectiveness of solid particle discharge.

[0024] In this invention, movable baffles 13 are provided in both the left channel 101 and the right channel 102. The baffles 13 move radially in the left channel 101 and the right channel 102. The baffles 13 and the nozzles 4 are located on opposite sides of the purification channel 1, with the baffles 13 positioned on the side of the nozzles 4 closest to the connecting pipe 2. An electric telescopic rod 14 is connected to the end of the baffles 13 away from the nozzles 4. The outer edge of the baffles 13 slides in contact with the side of the purification channel 1. During use, the extension and retraction of the baffles 13 can control the flow area of ​​the corresponding channel at that position. The more the baffles 13 extend inward, the more gas flows. The smaller the channel and the closer it is to the nozzle 4, the greater the air pressure at the nozzle 4 when the filter plate 6 is blocked, causing excessive air pressure. The filter plate 6 will deflect to clear the blockage, thus extending the baffle 13 to prevent the airflow from rushing out from a position far from the nozzle 4 without fully contacting the treatment liquid. When the filter plate 6 deflects due to excessive accumulation of solid particles, the air pressure at the nozzle 4 will suddenly decrease because the gap is opened. Therefore, when the air pressure is too low, the baffle 13 also needs to extend to prevent the airflow from flowing directly out from the gap. This ensures the completeness and effectiveness of the exhaust gas purification treatment during the process of clearing the airflow channel.

[0025] In this invention, multiple air holes are provided on the side of the baffle 13. A storage box 15 is installed outside the purification channel 1 at a position corresponding to the baffle 13. The air holes on the baffle 13 can prevent complete blockage of the airflow. Furthermore, the baffle 13 is positioned in the direction of the nozzle 4 toward the connecting pipe 2, which ensures that the airflow passing through the air holes can also come into contact with the treatment liquid.

[0026] Example 2: Refer to Figures 1-8A purification device for activated carbon production, based on Example 1, includes a collision plate 16 between the filter plate 6 and the baffle 13. Slide rails 17 are installed on the inner walls of both sides of the purification channel 1 at positions corresponding to the collision plate 16. Slider blocks are fixed at positions corresponding to the collision plate 16 and slide rails 17, and these sliders slide within the slide rails 17. The slide rails 17 are inclined downwards towards the middle of the lower channel 103 and are designed as an arc-shaped structure with the middle position arched outwards. An elastic rope 18 connects the end of the collision plate 16 near the baffle 13 to the end of the baffle 13 facing the nozzle 4. Under normal conditions, the baffle 13 is in a contracted state away from the nozzle 4, at which point the gas flow area corresponding to the baffle 13 is at its maximum, and the sliders at both ends of the collision plate 16 are at the bottom of the slide rails 17, while the collision plate 16 remains horizontal. After the airflow enters and passes through the area of ​​nozzle 4, a portion of the airflow or treatment liquid in the middle position impacts the top of the collision plate 16 and moves in the opposite direction, thereby improving the contact treatment effect between the airflow and the treatment liquid. When the baffle 13 extends inward close to the nozzle 4 to reduce the gas flow area, the collision plate 16 is pulled so that the slider moves upward along the slide rail 17. The collision plate 16 gradually tilts and moves outward close to the baffle 13. The collision plate 16 tilts downward towards the lower channel 103 and gradually becomes more vertical. This causes a portion of the airflow passing through the air hole to impact the inclined surface of the collision plate 16 and flow back towards the nozzle 4, thereby ensuring the contact effect between the airflow and the treatment liquid when the air pressure is too high. Thus, the combined operation of the baffle 13 and the collision plate 16 effectively improves the purification treatment effect of the exhaust gas.
