Description

Technical Field

[0001] The present invention relates to the technical field of enameled wire waste gas treatment, and in particular to a waste gas treatment device for thermal baking treatment of ultra-fine special enameled wire paint films and a treatment process thereof. Background Art

[0002] Ultrafine specialty enameled wire, due to its small wire diameter and special insulating paint film, is suitable for scenarios with extremely high electrical performance requirements, limited space, or high-density wiring. During its production process, the heat drying of the paint film is a key step. This process produces waste gas containing organic solvents, paint film volatiles, formaldehyde, benzene, toluene, xylene and other harmful gases. During the heat drying process, the enameled wire is usually continuously passed through the oven. In the factory, large-scale exhaust gas treatment is required to protect the environment and worker health. Ultrafine specialty paints usually use high-quality, low-volatile organic solvents. These solvents are released into the air during the drying process and may contain higher levels than the solvents used in general enameled wire.

[0003] In the prior art, activated carbon adsorption is generally connected to multiple adsorption chambers, each containing multiple layers of activated carbon beds. Typically, after saturating the activated carbon in one chamber with adsorption, the exhaust valve is closed and the desorption valve is opened for desorption. This approach often results in excessive adsorption in the activated carbon layer near the exhaust inlet, while the activated carbon layer farther from the exhaust inlet may not have reached saturation. In particular, ultra-fine specialty paints contain higher solvents than those used in general enameled wires. This can cause the activated carbon layer near the exhaust inlet to reach saturation faster, resulting in greater damage, which in turn reduces its regeneration frequency and shortens its service life.

[0004] In addition, the main component of activated carbon is carbon, which has a high specific surface area and a microporous structure. It is easy to produce debris during use due to factors such as physical wear, adsorption saturation, temperature changes, regeneration process and airflow impact. Therefore, during each maintenance, the staff needs to clean the carbon chips in time to avoid affecting the adsorption effect and avoid carbon chips catching fire at high temperatures after accumulation. However, at present, the activated carbon layer needs to be taken out and cleaned separately during cleaning, and the staff needs to reach into the adsorption cabin to clean it, which is time-consuming and labor-intensive. In addition, when putting the activated carbon layer back, friction and collision may also produce new carbon chips, resulting in poor cleaning effect.

[0005] In view of this, the present invention proposes an exhaust gas processor for thermal baking treatment of ultra-fine special enameled wire paint film and a treatment process thereof to compensate for and improve the deficiencies of the prior art. Summary of the Invention

[0017] The treatment process of the exhaust gas processor for thermal baking treatment of ultra-fine special enameled wire paint film includes the following steps:

[0018] Step 1: Pre-treatment of exhaust gas paint mist capture: First, use a paint mist collector, such as a wet scrubber or dry filter, to remove paint mist particles from the exhaust gas. Then, use an air pump to fill the air with air and mix it with a rotating convex disc to adjust the exhaust gas concentration entering the adsorption box so that the adsorption process is uniform and stable.

[0019] Step 2: Adsorption, desorption and catalytic combustion of activated carbon: The pretreated exhaust gas is sent to the feeding frame. The activated carbon has a large specific surface area and can effectively adsorb harmful gases such as organic solvents contained in the exhaust gas. After adsorption saturation, the adsorbed organic matter is desorbed from the feeding frame by a hot air blower using low wind speed and high hot air to form a high concentration of organic gas, so that the activated carbon can be regenerated, or the activated carbon needs to be replaced when it reaches saturation. Then, the high concentration of organic waste gas desorbed from the feeding frame can be collected through a desorption tube and then treated using catalytic combustion technology. Under the action of the catalyst, the organic matter reacts with oxygen at a lower temperature and is converted into harmless carbon dioxide and water.

[0020] Step 3: Heat recovery and emission: The heat energy generated during the catalytic combustion process can be recovered through a heat exchanger and used to preheat the exhaust gas entering the catalytic combustion device or for other process steps. The treated exhaust gas is discharged into the atmosphere through a chimney. Before discharge, it is necessary to ensure that the pollutant concentration in the exhaust gas is lower than the national or local emission standards.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. For the activated carbon bed that is saturated with adsorption, the multi-layer adsorption beds can be switched layer by layer in a closed manner through the setting of a closed switching mechanism, so that the adsorption bed that is first saturated with adsorption near the exhaust gas inlet can be taken out for desorption, while the adsorption bed that has not yet reached the saturated state can continue to adsorb. In this way, the single-layer extraction and switching of the adsorption bed near the exhaust gas inlet can extend the service life and regeneration times of the adsorption bed, and avoid the situation where the adsorption bed at the exhaust gas inlet is damaged by the introduction of exhaust gas after it is saturated with adsorption. In addition, the setting of the turnover box can concentrate the desorption process and the process of replacing the activated carbon, which can not only timely and accurately desorb and regenerate the activated carbon in the adsorption bed, but also use the turnover box to drive the adsorption bed to change its position while the hot air blower remains stationary, ensuring that the two are relatively independent and operate effectively, which can improve production efficiency, make the adsorption system run continuously, and reduce production interruptions;

[0023] 2. Through the arrangement of the fixed block and the disc base, the fixed block is disengaged from the fan switch during each rotation of the disc base, and the fixed block is connected to the fan switch each time the disc base completes its rotation, so that the hot air blower is turned off when the flip box rotates and turned on when it is stationary, thereby avoiding turbulent air flow inside the flip box that causes the desorbed activated carbon to adsorb the organic solvent, and reducing the flipping resistance of the flip box. The disc base can assist the fixed block in moving accurately, increase the contact area between the flip box and the adsorption box, ensure the stability of the flipping of the flip box, and prevent the gas in the adsorption box from leaking into the air during the switching of the adsorption bed, thereby ensuring the stable operation of the equipment.

[0024] 3. By shaking the rotating plate, the second spring and the double grooves of the bevel in the anti-accumulation mechanism, maintenance personnel can scrape the bottom carbon chips to the exit position through the scraper when opening the door for maintenance, and then clean up the carbon chips concentrated at the exit, reducing cleaning time. There is no need for employees to reach into the adsorption cabin to clean the debris deep in the adsorption box. The arc design of the arc brush plate is convenient for collecting carbon chips, and the trapezoidal slopes on both sides of the top of the bottom plate can be used to collect the debris on the slope of the bottom plate with the arc brush plate. As the adsorption bed switches, the debris falls into the adsorption box, which is conducive to centralized collection. The double grooves with beveled edges make it possible for the second spring to shake off the carbon dust produced on the carbon bed each time the box door is opened, and a portion of the carbon dust is scraped off by the scraper at the same time. When the box door is closed, the two scrapers pass through the opening toward the edge of the V-shaped groove of the box door and approach each other. The scrapers transition from the outer transverse grooves of the double grooves with beveled edges along the V-shaped groove. Finally, the scrapers on both sides approach each other and run parallel without contacting the rotating plate and the bottom inner surface of the adsorption box, preventing the carbon dust from being pushed to the corner of the adsorption box. The box door can then be opened again to centrally scrape away the debris, effectively removing the accumulated carbon dust and keeping the bed clean and breathable.

[0025] 4. By setting up the anti-slip cone and trapezoidal block, when the trapezoidal block contacts the activated carbon during the process of replacing new activated carbon, the same spacing gaps can be squeezed between the two blocks, and they can be evenly arranged to prevent the activated carbon from sticking to each other and accumulating and catching fire. The anti-slip cone is used to increase the friction on the activated carbon, so that after the pressure strip fits the top of the activated carbon, the activated carbon remains stable and not easy to slip off, making it easier to push and pull the loading frame as a whole to replace the activated carbon, thereby improving the replacement efficiency. At the same time, it is beneficial for the second spring to shake off the carbon chips, so that there will be no more friction and collision between the activated carbons.

[0061] Embodiment 2 of the present invention

[0062] The treatment process of the exhaust gas processor for thermal baking treatment of ultra-fine special enameled wire paint film includes the following steps:

[0063] Step 1: Pre-treatment of exhaust gas paint mist capture: First, a paint mist collector, such as a wet scrubber or dry filter, is used to remove paint mist particles from the exhaust gas. Then, air is pumped in through the air pump 3 and mixed with the rotating convex disc 4 to adjust the exhaust gas concentration entering the adsorption box 1 so that the adsorption process is uniform and stable.

[0064] Step 2: Adsorption, desorption and catalytic combustion of activated carbon: The pretreated exhaust gas is fed into the feeding frame 64. The activated carbon has a large specific surface area and can effectively adsorb harmful gases such as organic solvents contained in the exhaust gas. After adsorption saturation, the hot air blower 514 uses a low wind speed and high hot air method to desorb the adsorbed organic matter from the feeding frame 64 to form a high-concentration organic gas, so that the activated carbon can be regenerated. Or the activated carbon needs to be replaced when it reaches saturation. Then, the high-concentration organic exhaust gas desorbed from the feeding frame 64 can be collected through the desorption pipe 52 and then treated using catalytic combustion technology. Under the action of the catalyst, the organic matter reacts with oxygen at a lower temperature and is converted into harmless carbon dioxide and water.

[0065] Step 3: Heat recovery and emission: The heat energy generated during the catalytic combustion process can be recovered through a heat exchanger and used to preheat the exhaust gas entering the catalytic combustion device or for other process steps. The treated exhaust gas is discharged into the atmosphere through a chimney. Before discharge, it is necessary to ensure that the pollutant concentration in the exhaust gas is lower than the national or local emission standards.

[0066] The complete usage steps and working principle of the above embodiment are as follows:

[0067] In the initial state: the adsorption bed 68 is located inside the adsorption box 1, the fixed block 510 and the fan switch 57 are in a mutually engaged state, the first spring 613 is in a compressed state, the third spring 620 and the second spring 616 are in a naturally relaxed state, the adjustment plate 63 is at the topmost position on the feeding frame 64, the box door 2 is in a closed state, and the two scrapers 621 are in a state of moving away from each other.

[0068] Main technical support: Silicone membrane 521 has high air permeability and corrosion resistance, which can effectively prevent the invasion of moisture and particles. This membrane can achieve ventilation from the outside to the inside through tiny channels, but will not produce reverse ventilation due to internal airflow pressure.

[0069] During use, whenever the activated carbon inside the adsorption bed 68 closest to the air inlet of the adsorption box 1 is saturated with adsorption, the cylinder 59 is activated by the external control system to push the lifting frame 512 downward, so that the main electromagnet 511 and the sub-electromagnet 69 are tightly attracted, and then the adsorption bed 68 is moved upward as a whole and enters the inside of the flip box 51 from the initial state. The valve of the adsorption box 1 is opened when the main electromagnet 511 is adsorbed, and is closed after the adsorption bed 68 enters the flip box 51 to prevent continuous leakage of gas. At this time, the multiple adsorption beds 68 arranged inside the adsorption box 1 can be pushed forward one grid as a whole by the squeezing force of the first spring 613 on the squeezing plate 62, that is, the adsorption bed 68 originally in the second position becomes the first, and at this time the fixed block 510 and The fan switches 57 are connected to each other, so the hot air blower 514 is in the starting state. By setting a silicone membrane 521 in the middle of the air inlet 58, ventilation can be maintained while preventing gas leakage in the flip box 51. There is also a wind shield 520 that can be blown by the air flow when the hot air blower 514 is turned on, and the air inlet 58 is rotated to open. When the hot air blower 514 is turned off, the wind shield 520 also remains vertically attached to the flip box 51 to further prevent leakage, and blows hot air to the adsorption bed 68 to heat and desorb the saturated activated carbon in the adsorption bed 68. The hot air carries a high concentration of organic gas into the desorption tube 52, and the concentration of the gas is detected by the concentration detector 54. If the concentration is lower than the normal value, a warning is issued, and the staff needs to open the corresponding refueling door 55 to remove the adsorption gas. The bed 68 is taken out and the internal activated carbon is replaced. If the concentration detected by the concentration detector 54 remains within the normal range, the external control system starts the servo motor 522 to drive the gear 523 to rotate, so that the gear 523 moves along the teeth 524. Since the teeth 524 are evenly arranged along the semicircular arc of the semicircular groove 526, the rotating sleeve 518 will rotate 180 degrees as the gear 523 moves, and then the rotating sleeve 518 drives the flip box 51 to flip 180 degrees as a whole. During the flipping process, the fixed block 510 and the fan switch 57 are separated from each other, so the hot air blower 514 is in the off state, avoiding the turbulence of the air flow inside the flip box 51 so that the desorbed activated carbon is adsorbed to the organic solvent, and reducing the flipping resistance of the flip box 51. After the flip box 51 is flipped The fixed block 510 is connected to another fan switch 57, so that the hot air blower 514 is restored to the on state, which is convenient for the next desorption. After the flip box 51 is flipped, the adsorption bed 68 will be moved to the opposite side of the guide plate 516, that is, from the position closest to the air inlet of the adsorption box 1 to the position farthest from the air inlet of the adsorption box 1. At this time, the cylinder 59 is used again to push the adsorption bed 68 downward, so that the desorbed and regenerated adsorption bed 68 passes through the two extrusion plates 62 in turn, and the first spring 613 is compressed to move the extrusion plate 62 toward the second partition 61. The adsorption bed 68 that was originally closest to the air inlet of the adsorption box 1 is now at the last one, and this reciprocating process continuously extracts the carbon layer from the head of the activated carbon layer, and continuously replenishes the regenerated or replaced carbon layer from the tail after desorption.By replacing the carbon layers one by one in this way, the adsorption and desorption process can be continuously and effectively carried out, ensuring that each layer of the adsorption bed 68 is in an adsorption saturation state and can desorb in time after reaching the saturation state, effectively reducing the damage degree of the activated carbon after each adsorption;

[0070] Please refer to the above working process Figures 1 to 6 .

[0071] Furthermore, when replacing the activated carbon in the adsorption bed 68, the worker can pull out the loading frame 64 in the adsorption bed 68, lay it flat on the ground, and then place the new activated carbon in the interlayer of the loading frame 64 in sequence, and then rotate the threaded rod 67 to move the adjustment plate 63 downward from the initial state, thereby driving the layer 610 of each layer to move downward. The bottom of the trapezoidal block 611 on the layer 610 is set to a trapezoidal shape, and the spacing distance of the layer 610 matches the size of the activated carbon. When it comes into contact with the activated carbon, it can be squeezed to both sides so that the placed activated carbon is spaced apart from each other. There are gaps, and they are evenly distributed. The anti-slip cone 612 is used to increase the friction on the activated carbon, so that after the pressure strip 610 is attached to the top of the activated carbon, the activated carbon is not easy to slip off. At this time, the loading frame 64 can be lifted up from the flat state, and the activated carbon is evenly and firmly arranged on the loading frame 64. Then the loading frame 64 is returned to the adsorption bed 68. On the one hand, the activated carbon is placed quickly and stably, and it is not easy to accidentally touch and drop the activated carbon during the loading process. On the other hand, the evenly and spaced activated carbon can effectively absorb organic solvents in the exhaust gas and prevent the activated carbon from sticking to each other and accumulating and catching fire.

[0072] Furthermore, during the desorption and replacement process of the adsorption bed 68, the activated carbon therein will drop carbon dust onto the surface of the bottom plate 515 due to factors such as heating and collision. During the flipping process of the flip box 51, since the arc-shaped brush plate 519 is slidably connected to the outer wall of the rotating sleeve 518, when it rotates through the air inlet 58, the arc-shaped brush plate 519 will not immediately rotate with the rotating sleeve 518 due to inertia, and the bottom plate 515 is fixedly connected to the rotating sleeve 518 and will move synchronously with the rotating sleeve 518. Therefore, each time the flip box 51 is flipped, the bottom plate 515 will slide at the bottom of the arc-shaped brush plate 519, and the carbon dust on the surface of the bottom plate 515 can be swept away by the top edge of the bottom plate 515. The arc-shaped design of the arc-shaped brush plate 519 facilitates the collection of carbon dust, and Both sides of the top of the bottom plate 515 are set to be trapezoidal slopes, so that the carbon dust located at the top edge of the bottom plate 515 can easily fall into the adsorption box 1 when entering the adsorption box 1 along with the adsorption bed 68, thereby preventing the accumulation of carbon dust inside the flip box 51. Then, during each maintenance, by opening the box door 2, the second push rod 618, the first push rod 65 and the support plate 619 can be driven to move toward the box door 2, and a pair of scrapers 621 located on the support plate 619 slide along the vertical groove edges of the beveled double groove 614 on the upper and lower sides of the beveled double groove 614 respectively, and in the sliding process, the top scraper 621 continuously squeezes the multiple rotating plates 615 to compress the second spring 616. After the top scraper 621 passes the rotating plate 615, the second spring 616 passes The rotating plate 615 will be reset by itself, and part of the elastic force of the second spring 616 will be transmitted to the leak plate 617. Under the continuous action of multiple second springs 616, the leak plate 617 will vibrate slightly, and then the leak plate 617 will drive the activated carbon in the multiple adsorption beds 68 on the top to vibrate synchronously, shaking off the excess carbon chips, so that the debris in the flip box 51 and the adsorption bed 68 will fall on the bottom inner surface of the adsorption box 1. When the scraper 621 at the bottom moves toward the box door 2, it can scrape all the debris to a position close to the box door 2, which is convenient for the staff to clean. There is no need to clean the adsorption bed 68 separately or lean into the interior of the adsorption box 1, saving cleaning time. In addition, since the second push rod 618 is rotatably connected to the first push rod 65 and the box door 2, Therefore, when the box door 2 is opened and rotated outward by the staff, the adsorption bed 68 can rotate accordingly without hindering the movement of the first push rod 65. If the carbon dust cannot be completely cleaned by scraping once, the box door 2 can be closed. Similarly, the support plate 619 is pushed to move away from the box door 2. At this time, the two scrapers 621 approach each other along the edges of the V-shaped grooves of the beveled double grooves 614 until they slide to the middle of the beveled double grooves 614 and slide horizontally. At this time, the two scrapers 621 do not contact the rotating plate 615 and the bottom inner surface of the adsorption box 1 to prevent movement obstruction or pushing the carbon dust to the corner of the adsorption box 1, which is inconvenient to clean. When the two scrapers 621 reach the corner of the adsorption box 1, the two scrapers 621 are reset by the third spring 620, and the box door 2 is also completely closed.The door 2 can be opened again for cleaning to increase the cleaning effect;
