Description

Technical Field

[0001] This utility model relates to the field of NMP treatment technology, specifically to an NMP leakage storage and treatment device that uniformly sprays and absorbs NMP leaks. Background Technology

[0002] NMP is a commonly used organic solvent, widely used in industries such as lithium battery manufacturing, electronic component cleaning, coatings, adhesives, and pharmaceuticals. NMP is a volatile organic compound that will continuously volatilize during the production process. In order to prevent the diffusion of volatile gases, it needs to be recycled before it can be discharged.

[0003] In the prior art, Chinese Patent No. CN222900661U discloses an NMP exhaust gas treatment device, including a recovery tower. The recovery tower has a demister, a packing layer, and a collection chamber arranged inside. A spray assembly is installed on the top surface of the packing layer, and a rotating shaft is located at the center of the spray assembly. A drive motor is also installed at the top of the recovery tower and is connected to the rotating shaft for transmission. An air inlet pipe and a water outlet pipe are also provided on the side wall of the recovery tower. An atomizing assembly is installed on the air inlet pipe, and an exhaust pipe is also provided at the top of the recovery tower. Based on the existing recovery tower, an improvement is made by using a method of mixing and conveying atomized water with exhaust gas instead of the traditional gas-liquid mixing. In this structure, the diffusion range of atomized water is large. Compared with the traditional gas-liquid mixing, atomized water can be mixed into the exhaust gas for synchronous conveying. Therefore, it can contact NMP in the exhaust gas for a longer time, further improving its absorption effect. Moreover, it can be conveyed under negative pressure, eliminating the need for an additional power source and greatly reducing the modification cost.

[0004] The aforementioned treatment device uses an atomizing component on the air inlet pipe to mix and transport exhaust gas instead of the traditional gas-liquid mixing method. However, during use, NMP exhaust gas dissolved in water will generate water droplets that adhere to the inner wall of the device, making it difficult to discharge and requiring regular cleaning by staff, thus reducing the effectiveness of the device. Utility Model Content

[0005] The purpose of this invention is to provide a uniformly sprayed and absorbed NMP leakage storage and treatment device to solve the problem mentioned in the background art that NMP waste gas dissolved in water will produce water droplets that are adsorbed on the inner wall of the device, making it difficult to discharge and requiring regular cleaning by staff, thereby reducing the effectiveness of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniformly sprayed and absorbed NMP leak storage and treatment device, including a stable fixed frame, a treatment box welded to the fixed frame, and an air inlet pipe installed at the bottom of the treatment box, and further including: an air guide plate welded to the inner wall of the treatment box.

[0007] The processing box is fixedly equipped with an inner box, and the inner box is equipped with a self-rotating structure, which uniformly treats the NMP exhaust gas.

[0008] The bottom of the processing box is equipped with drain pipes distributed at equal angles, and the top of the processing box is equipped with an exhaust pipe.

[0009] Preferably, the air guide plate has a through groove in the middle and fixed holes with equal angles at the bottom, and the air guide plate is conical in shape. The through groove and the top of the air intake pipe are interconnected.

[0010] Preferably, the top of the inner box is connected to a top plate, and the top plate has first connecting holes distributed at equal angles; the bottom of the inner box is connected to a bottom plate, and the bottom plate has second connecting holes distributed at equal angles.

[0011] Preferably, the self-rotating structure includes a sleeve that penetrates the top plate, and the inside of the sleeve is connected to a water inlet pipe, and a connecting blade is provided below the water inlet pipe.

[0012] Preferably, a rotating rod is vertically provided inside the inner box, and the bottom of the rotating rod is fixed to a support rod, and the end of the support rod away from the rotating rod is fixed to the inner wall of the processing box.

[0013] Preferably, the outer bearing of the rotating rod is connected to a sleeve rod, and the outer wall of the sleeve rod is fitted with a connecting blade, a base plate and a fixing plate by screws, and a scraper is connected to the side of the fixing plate away from the sleeve rod.

[0014] Preferably, the bottom plate and the inner box are rotatably connected, and the inner box and the top plate are fixed together by screws.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The uniformly sprayed and absorbed NMP leakage storage and treatment device is equipped with a self-rotating structure. The self-rotating structure includes a sleeve that penetrates the top plate, and a water inlet pipe is connected inside the sleeve. A connecting blade is provided below the water inlet pipe. When the water inlet pipe drains water into the inner box, it drives the connecting blade to rotate. The connecting blade drives the sleeve rod to rotate. The rotation effect can be achieved without additional drive equipment, thus achieving the purpose of energy saving.

[0017] Furthermore, a fixing plate is installed on the outer wall of the sleeve rod. As the sleeve rod rotates, the fixing plate will rotate together, and the fixing plate will drive the scraper to rotate. The side of the scraper away from the fixing plate is in contact with the inner wall of the processing box, so that the inner wall of the processing box can be cleaned during the processing.

[0018] Furthermore, a second connecting hole is provided on the bottom plate, so that water will fall from the second connecting hole and come into contact with the rising exhaust gas. The connecting blade drives the sleeve to rotate, and the sleeve drives the bottom plate to rotate, so that the water falls in a downward spraying form. This allows the water to come into better contact with and dissolve the exhaust gas, increases the contact area, and thus makes the dissolution effect of the exhaust gas better.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6This utility model provides the following technical solution: a uniformly sprayed and absorbed NMP leakage storage and treatment device, including a stable fixed frame 1, a treatment box 2 welded to the fixed frame 1, and an air inlet pipe 3 installed at the bottom of the treatment box 2; it also includes: an air guide plate 4 welded to the inner wall of the treatment box 2, a through groove 5 opened in the middle of the interior of the air guide plate 4, and fixed holes 6 evenly distributed at the bottom of the air guide plate 4, and the air guide plate 4 is conical in shape; the through groove 5 and the top of the air inlet pipe 3 are interconnected; an inner box 7 is fixedly installed inside the treatment box 2, and a self-rotating structure is provided inside the inner box 7; through self-rotation... The structure uniformly treats NMP exhaust gas. The self-rotating structure includes a sleeve 10 that penetrates the top plate 8, and an inlet pipe 11 is connected inside the sleeve 10. A connecting blade 15 is provided below the inlet pipe 11. A rotating rod 12 is vertically provided inside the inner box 7. The bottom of the rotating rod 12 is fixed to a support rod 13, and the end of the support rod 13 away from the rotating rod 12 is fixed to the inner wall of the treatment box 2. A sleeve rod 14 is connected to the outer side of the rotating rod 12 by a bearing. A connecting blade 15, a bottom plate 16, and a fixing plate 18 are installed on the outer wall of the sleeve rod 14 by screws. A scraper 19 is connected to the side of the fixing plate 18 away from the sleeve rod 14.

[0028] In use, NMP exhaust gas can be introduced into the treatment chamber 2 through the inlet pipe 3. An air guide plate 4 is installed inside the treatment chamber 2, and a through groove 5 in the middle of the air guide plate 4 is connected to the top of the inlet pipe 3. Therefore, the NMP exhaust gas entering through the inlet pipe 3 will flow upward through the through groove 5 into the treatment chamber 2. Simultaneously with the exhaust gas introduction, the external water supply device is turned on, allowing water to enter through the water inlet pipe 11. The outlet end of the water inlet pipe 11 is located inside the inner casing 7, and a connecting blade 15 is installed below the water inlet pipe 11. 15 is fixed to the outer wall of the sleeve rod 14, so when the water inlet pipe 11 drains water into the inner box 7, it will drive the connecting blade 15 to rotate. The connecting blade 15 drives the sleeve rod 14 to rotate, so that the rotation effect can be achieved without additional drive equipment, thereby reducing energy consumption. As the sleeve rod 14 rotates, it will drive the fixing plate 18 to rotate together, and the fixing plate 18 will drive the scraper 19 to rotate. The side of the scraper 19 away from the fixing plate 18 is in contact with the inner wall of the processing box 2, so that the inner wall of the processing box 2 can be cleaned during the processing.

[0029] Example 2: Figure 3 and Figure 5 As shown, based on Example 1, the effect of uniformly spraying water is also disclosed, and its specific structure is as follows:

[0030] The bottom of the processing box 2 is provided with drain pipes 20 distributed at equal angles, and the top of the processing box 2 is provided with exhaust pipes 21.

The bottom of the inner box 7 is connected to a bottom plate 16, and the bottom plate 16 is provided with second connecting holes 17 distributed at equal angles. The bottom plate 16 and the inner box 7 are rotatably connected, and the inner box 7 and the top plate 8 are fixed together by screws.

[0031] During the water delivery process in the inlet pipe 11, the connecting blade 15 is driven to rotate. At the same time, a second connecting hole 17 is provided on the bottom plate 16, so that water will fall from the second connecting hole 17 and come into contact with the rising exhaust gas. The connecting blade 15 drives the sleeve rod 14 to rotate, and the sleeve rod 14 drives the bottom plate 16 to rotate, so that the water will fall in a downward spraying form, so that the water and exhaust gas can come into better contact and dissolve, increasing the contact area and thus improving the dissolution effect of the exhaust gas. The water droplets produced by dissolution are adsorbed on the inner wall of the treatment box 2 and will be scraped off by the scraper 19 and drip down. Since the air guide plate 4 is conical and a fixing hole 6 is provided at the bottom of the air guide plate 4, the dissolved water will flow out through the fixing hole 6 and finally be discharged outward from the drain pipe 20. A first connecting hole 9 is provided on the top plate 8, so that the dissolved gas will continue to rise through the first connecting hole 9 and finally be discharged from the exhaust pipe 21.
