Description

Technical Field

[0001] This application relates to the field of environmental engineering technology, specifically to a regeneration treatment device for SNCR solid denitrification catalyst. Background Technology

[0002] With increasingly stringent environmental regulations, industrial flue gas denitrification technology has become a key link in air pollution control. Selective non-catalytic reduction (SNCR) technology is widely used due to its advantages such as low cost and simple operation. However, its core solid denitrification catalyst is prone to deactivation due to problems such as ash accumulation, sintering, and poisoning after long-term operation. At present, tens of thousands of tons of waste catalysts are generated globally every year. Traditional landfill or chemical dissolution treatment methods pose the risk of secondary pollution and waste resources seriously.

[0003] However, existing methods of cleaning catalyst surface deposits with acid and alkali solutions produce excessive harmful odors and are inconvenient to remove, which can pollute the environment and, in severe cases, cause respiratory hazards to personnel, greatly reducing safety. To solve these problems, a regeneration treatment device for SNCR solid denitrification catalysts is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a regeneration treatment device for SNCR solid denitrification catalysts, which has advantages such as removing harmful odors and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a regeneration treatment device for SNCR solid denitrification catalyst, comprising a support plate, a sealed box, a clamping mechanism, a spray denitrification mechanism, a purification mechanism, and a ventilation mechanism. The purification mechanism includes fixed boxes fixedly connected to both sides of the sealed box. Concave plates are fixedly connected inside each of the two fixed boxes. There are four sets of concave plates. First support frames are slidably connected inside two sets of concave plates, and second support frames are slidably connected inside the other two sets of concave plates. Activated carbon plates are installed inside each of the two first support frames, and Hanzi purification plates are installed inside each of the two second support frames. Handles are fixedly connected to the tops of both the first and second support frames. There are four handles. Breathable cloth is fitted onto the sides of both fixed boxes. Several iron nails are inserted into the interior of the breathable cloth and the interior of the fixed boxes.

[0006] The above scheme, through the setting of a purification mechanism, allows for the placement of activated carbon plates in two first support frames and Hanzi purification plates in two second support frames, which are used to adsorb and decompose harmful gases generated during the treatment process. Each of the first and second support frames has four handles on its top for easy replacement of purification materials by staff. The sides of the fixed box are covered with breathable cloth, which is fixed to the inside of the fixed box by several iron nails. This ensures gas flow while preventing large particles of impurities from entering the fixed box and affecting the purification effect.

[0007] Furthermore, a sealing box is fixedly connected to the top of the support plate, and a support leg is fixedly connected to the bottom of the support plate. There are four support legs, and a round pad is fixedly connected to the bottom end of each of the four support legs.

[0008] With the above scheme, the support plate serves as the basic load-bearing component of the equipment. The top is fixedly connected to the sealed box, and the bottom is supported by four support legs. The round pads at the bottom of the support legs increase the contact area with the ground, enhance the stability of the equipment, and prevent the catalyst regeneration effect from being affected by shaking during the process.

[0009] Furthermore, the clamping mechanism includes hydraulic cylinders fixedly connected to both sides of the sealing box. Hydraulic rods are fixedly installed inside the two hydraulic cylinders, and clamping plates are fixedly connected to one end of each of the two hydraulic rods. Rubber pads are provided on the surface of each of the two clamping plates.

[0010] With the above scheme, the clamping mechanism is driven by hydraulic cylinders on both sides of the sealed box. The hydraulic rods inside the hydraulic cylinders can be precisely controlled to extend and retract. When the catalyst needs to be processed, the hydraulic rods push the clamping plate. The rubber pads on the surface can not only firmly fix the catalyst, but also avoid damage to the catalyst during the clamping process. It is suitable for solid denitrification catalysts of different specifications and shapes.

[0011] Furthermore, the spray denitrification mechanism includes a liquid storage container fixedly connected to the top of the sealed box, a liquid pump fixedly installed at the bottom of the liquid storage container, a main pipe fixedly connected to the bottom end of each liquid pump, and four secondary pipes fixedly connected to the surface of each main pipe. Spray nozzles are fixedly installed on the surface of each of the four secondary pipes and the surface of the main pipe, making a total of six spray nozzles. An injection pipe is fixedly connected to the top of the liquid storage container, and a sealing plug is snapped into the inside of the injection pipe.

[0012] The above scheme uses a liquid storage container as its core. The liquid injection pipe at the top is used to add the treatment liquid. The sealing plug can prevent liquid evaporation and impurities from entering. The liquid pump draws out the liquid from the storage container, which is then distributed to four auxiliary pipes through the main pipe. Finally, it is evenly sprayed onto the catalyst surface in the sealed box through six nozzles, achieving efficient cleaning and removal of deposits on the catalyst surface and enabling the catalyst to be regenerated.

[0013] Furthermore, a drain pipe is fixedly connected to the side of the sealed box, and a solenoid valve is fixedly installed on the surface of the drain pipe.

[0014] With the above solution, the drain pipe installed on the side of the sealed box is connected to an external waste liquid collection device. The solenoid valve can precisely control the timing of the drain according to the processing progress, and promptly discharge the waste liquid generated during the processing to prevent the waste liquid from accumulating in the sealed box and affecting the processing effect.

[0015] Furthermore, a sealing door is movably connected to the side of the sealed box via a hinge, and a transparent glass is provided on the side of the sealing door. Magnetic blocks are provided on both the side of the sealed box and the side of the sealing door, and there are two sets of magnetic blocks. A handle is fixedly connected to the side of the sealing door, and a sealing gasket is provided on the side of the sealing door.

[0016] With the above solution, the sealing door on the side of the sealed box opens and closes via hinges, and the transparent glass allows staff to observe the catalyst processing status inside the box in real time. Two sets of magnetic blocks attract each other and act as a sealing gasket to ensure the sealing of the door when closed, preventing the leakage of harmful gases. The handle makes it easy for staff to open and close the sealing door.

[0017] Furthermore, the ventilation mechanism includes a bellows fixedly connected to the side of the sealed box. A drive motor is fixedly mounted on the side of the bellows via a mounting plate. A bearing is fixedly connected to the side of the bellows. A rotating shaft is rotatably connected inside the bearing. One end of the rotating shaft is fixedly connected to the output shaft of the drive motor. Six fan blades are fixedly connected to the surface of the rotating shaft.

[0018] The above scheme provides installation space for the fan blades in the ventilation mechanism. The drive motor drives the six fan blades to rotate at high speed through the shaft, which accelerates the air circulation in the sealed box, allowing the harmful gases generated during the treatment process to enter the purification mechanism more quickly. At the same time, it helps the treatment liquid to be evenly distributed and dried quickly on the catalyst surface.

[0019] Furthermore, the inner bottom of the sealed box is provided with a slope, and the surface of the slope is covered with a layer of hydrophobic material.

[0020] The above solution, with its sloped bottom and hydrophobic material, allows the waste liquid generated during the process to flow quickly to the drain pipe, preventing waste liquid from remaining inside the box, ensuring the cleanliness of the inside of the sealed box, and improving the efficiency and quality of catalyst regeneration.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This regeneration equipment for SNCR solid denitrification catalyst, through the setting of a purification mechanism, can install activated carbon plates in two first support frames and Hanzi purification plates in two second support frames to adsorb and decompose harmful gases generated during the treatment process. The top of both the first and second support frames is equipped with four handles to facilitate the replacement of purification materials by the staff. The side of the fixed box is covered with a breathable cloth, which is fixed to the inside of the fixed box by several iron nails. While ensuring gas circulation, it prevents large particulate impurities from entering the fixed box and affecting the purification effect. Attached Figure Description

[0027] Please see Figure 1 and Figure 3 The spray denitrification mechanism 4 includes a liquid storage container 401 fixedly connected to the top of the sealed box 2. A liquid pump 402 is fixedly installed at the bottom of the liquid storage container 401. A main pipe 403 is fixedly connected to the bottom of each of the liquid pumps 402.

To prevent liquid evaporation and impurities from entering, the liquid pump 402 extracts the liquid from the storage container 401, which is then diverted through the main pipe 403 to four auxiliary pipes 404.

[0028] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6A sealing door 10 is movably connected to the side of the sealed box 2 via a hinge. A transparent glass 11 is provided on the side of the sealing door 10. Magnetic blocks 13 are provided on both the side of the sealed box 2 and the side of the sealing door 10; there are two sets of magnetic blocks 13. A handle 12 is fixedly connected to the side of the sealing door 10, and a sealing gasket 16 is provided on the side of the sealing door 10. The sealing door 10 on the side of the sealed box 2 opens and closes via a hinge. The transparent glass 11 allows staff to observe the catalyst processing status inside the box in real time.

An internal rotating shaft 1404 is connected, one end of which is fixedly connected to the output shaft of the drive motor 1402. Fan blades 1405, consisting of six blades, are fixedly connected to the surface of the rotating shaft 1404. The air box 1401 in the ventilation mechanism 14 provides installation space for the fan blades 1405. The drive motor 1402 drives the six fan blades 1405 to rotate at high speed through the rotating shaft 1404, accelerating the air circulation inside the sealed box 2. This allows harmful gases generated during the treatment process to enter the purification mechanism 5 more quickly, while also helping the treatment liquid to be evenly distributed and dried quickly on the catalyst surface. A slope 15 is provided at the bottom of the sealed box 2, and a layer of hydrophobic material is laid on the surface of the slope 15. The slope 15 at the bottom of the sealed box 2, combined with the hydrophobic material, allows the waste liquid generated during the treatment process to flow quickly to the drain pipe 6, preventing waste liquid from remaining inside the box, ensuring the cleanliness of the inside of the sealed box 2, and improving the efficiency and quality of catalyst regeneration treatment.

[0029] In this embodiment, a regeneration device for an SNCR solid denitrification catalyst is described. It should be noted that by setting a purification mechanism 5, activated carbon plates 504 are installed in two first support frames 503, and Hanzi purification plates 506 are installed in two second support frames 505. These are used to adsorb and decompose harmful gases generated during the treatment process. Each of the first and second support frames 503 has four handles 507 at its top for easy replacement of purification materials. A breathable cloth 508 is fitted onto the side of the fixed box 501, and is secured to the inside of the fixed box 501 by several iron nails 509. This ensures gas flow while preventing large particles of impurities from entering the fixed box 501 and affecting the purification effect.

[0030] The working principle of the above embodiment is as follows: First, the SNCR solid denitrification catalyst to be regenerated is placed in the sealed box 2. The clamping mechanism 3 is activated, and the hydraulic cylinders 301 on both sides of the sealed box 2 drive the hydraulic rods 302 to extend, which moves the clamping plate 303 with rubber pads 304 on its surface towards the center. The rubber pads 304 are tightly attached to the catalyst, and the catalyst is firmly fixed by a stable clamping force to prevent the catalyst from shifting during the process. Then, the operator holds the handle 12 to close the sealed door 10, and then locks the sealed door 10 with the magnetism of the magnetic block 13. Next, the operator adds a suitable treatment liquid through the injection pipe 406 at the top of the liquid storage container 401, and uses a sealed... The injection pipe 406 is sealed by the plug 407. Then, the spray denitrification mechanism 4 is activated. The liquid pump 402 at the bottom of the storage container 401 starts, drawing out the treatment liquid. This liquid is then diverted through the main pipe 403 to four auxiliary pipes 404, and finally sprayed evenly as a mist onto the catalyst surface inside the sealed box 2 through six nozzles 405. The treatment liquid reacts with the accumulated dust and poisoned substances on the catalyst surface, gradually achieving the cleaning and regeneration of the catalyst. During this process, the ventilation mechanism 14 plays a role. The drive motor 1402 inside the side air box 1401 of the sealed box 2 starts, driving the rotating shaft 1404 to rotate. This causes the six fan blades 1405 fixed to the surface of the rotating shaft 1404 to rotate at high speed, accelerating the rotation of the sealed box. The airflow within the sealed chamber 2 serves two purposes. First, it helps the treatment liquid distribute more evenly on the catalyst surface, accelerating the reaction process. Second, it causes harmful gases generated during the treatment process to flow rapidly to the purification mechanisms 5 on both sides of the sealed chamber 2. In the purification mechanisms 5, the air containing harmful gases first passes through the activated carbon plate 504 within the first support frame 503. The activated carbon plate 504, with its abundant pore structure and strong adsorption capacity, adsorbs some of the harmful gases and impurities. Subsequently, the air continues to pass through the Hanzi purification plate 506 within the second support frame 505. The Hanzi purification plate 506 further decomposes and adsorbs the remaining harmful gases. After this double purification, the air passes through the breathable cloth 5. 08. Next, the impurities in the gas are filtered out, and clean air can be discharged afterward, effectively preventing the leakage of harmful gases from causing harm to the environment and personnel. During the catalyst treatment, real-time observation can be carried out through the transparent glass 11. After the catalyst treatment is completed, the solenoid valve 7 on the surface of the drain pipe 6 is opened. Since the bottom of the sealed box 2 is set with a slope 15 and the surface is covered with a hydrophobic material, the waste liquid generated during the treatment flows quickly along the slope 15 to the drain pipe 6 under the action of gravity, and is discharged to the external waste liquid collection device through the drain pipe 6. Finally, all mechanisms are closed, and the operator opens the sealed door 10 through the handle 12 to take out the regenerated catalyst, thus completing the entire regeneration process.
