Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalytic devices, and in particular to a multi-layer structure catalytic efficiency enhancement device. Background Technology
[0002] Sulfuric acid, as a strong acid and multifunctional chemical raw material, plays an irreplaceable core role in industry, agriculture, scientific research, and environmental protection. Its strong acidity enables sulfuric acid to participate efficiently in neutralization, hydrolysis, and esterification reactions. For example, in fertilizer production, it reacts with phosphate rock powder to produce soluble phosphate fertilizers such as superphosphate, providing key nutrients for agriculture. In petroleum refining, it is used as a desulfurizing agent to remove sulfides from crude oil, reducing sulfur content to meet environmental standards. In metal processing, it is used as a pickling solution to remove oxide scale from metal surfaces, providing a clean base for subsequent coating or electroplating.
[0003] Sulfuric acid catalyst layer catalysis is a core step in sulfuric acid production, accelerating the oxidation of sulfur dioxide to sulfur trioxide through the action of a catalyst. However, with increasingly stringent requirements for efficiency, environmental protection, and cost control in industrial production, traditional sulfuric acid catalysis technology has gradually revealed many limitations. In the traditional sulfuric acid catalysis process, the contact between the catalyst and the reactants is not uniform enough, resulting in a slow reaction rate and difficulty in further improving the conversion rate. Especially in large-scale industrial production, the inefficient catalytic process directly restricts production efficiency and capacity, thus presenting certain drawbacks. Therefore, it is necessary to improve the catalytic efficiency.
[0004] Therefore, in order to solve the above problems, this application provides a multilayer structure catalytic efficiency enhancement device. Utility Model Content
[0005] This invention addresses the technical problems existing in the prior art by providing a multi-layer structure catalytic efficiency enhancement device.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-layer structure catalytic efficiency improvement device includes a homogenization cylinder. An external gear ring is fixedly installed on the top inner side of the homogenization cylinder. A stirring motor is installed on the top of the homogenization cylinder. The output shaft of the stirring motor passes through the external gear ring and is then installed on a support frame. A first gear is installed at each of the three corners at the top of the support frame. A fixed shaft is installed at the bottom of the first gear. A second gear is installed at the bottom of the fixed shaft, which passes through the support frame. A third gear is installed at the bottom of the support frame and close to the three second gears. A connecting rod is installed at the bottom of the third gear. A stirring rod is installed at the bottom of the connecting rod away from the third gear. Multiple sets of stirring blades are installed on the outer ring surface of the stirring rod. A catalytic chamber is installed at the bottom of the homogenization cylinder. A fixed pipe is installed at one end of the bottom inner wall of the catalytic chamber. Several component flow pipes are installed at equal intervals on the outside of the fixed pipe.
[0007] Preferably, the external gear ring meshes with the three sets of first gears, and when the stirring motor drives the support frame to rotate, the three sets of first gears rotate synchronously outside the external gear ring.
[0008] Preferably, the outer ring surface of the fixed shaft is rotatably connected to the interior of the support frame, and the second gear and the third gear mesh with each other.
[0009] Preferably, the top of the third gear is rotatably connected to the bottom of the support frame, and the bottom of the third gear is fixedly connected to the connecting rod.
[0010] Preferably, an air pump is installed at one end of the external part of the catalytic converter, and the output end of the air pump extends into the interior of the catalytic converter and is connected to a fixed pipe. Several sets of air outlet holes are opened on the diversion pipe.
[0011] Preferably, a feed inlet is installed at one top end of the homogenizing cylinder, a discharge outlet is installed at the bottom inner side of the homogenizing cylinder, the homogenizing cylinder is connected to the catalytic box through the discharge outlet, and a discharge outlet is installed at the outer end of the catalytic box away from the gas pump.
[0012] Preferably, exhaust ports are symmetrically provided on both sides of the top end of the catalytic converter.
[0013] The beneficial effects of this utility model are as follows: This multi-layer structure catalytic efficiency enhancement device uses a stirring motor to drive the support frame to rotate, which simultaneously drives the three sets of stirring rods and stirring blades at the bottom to stir and homogenize the internal materials. The first gear rotates synchronously along the outer gear ring, which drives the second gear to rotate through the fixed shaft. Since the second gear and the third gear mesh with each other, they synchronously drive the third gear to rotate. When the third gear rotates, it drives the single set of stirring rods and stirring blades to rotate through the connecting rod. Thus, while the three sets of stirring rods rotate along the support frame, the individual stirring rods rotate synchronously along the connecting rod, thereby increasing the stirring and homogenization efficiency. The gas pump injects gas into the fixed pipe and into the distribution pipe. The micropore design of the gas outlet allows the gas to be released in the form of microbubbles, increasing the gas-liquid contact area and avoiding side reactions caused by excessively high local concentrations. It is easy to operate and effectively improves its catalytic efficiency. Attached Figure Description

[0024] Example
[0025] A multi-layer structure catalytic efficiency enhancement device, referring to Figure 1 - Figure 5 The system includes a homogenizing cylinder 1, an outer gear ring 2 fixedly installed on the top inner side of the homogenizing cylinder 1, a stirring motor 3 installed on the top of the homogenizing cylinder 1, a support frame 4 installed after the output shaft of the stirring motor 3 passes through the outer gear ring 2, a first gear 5 is installed at each of the three corners of the top of the support frame 4, a fixed shaft 6 is installed at the bottom of the first gear 5, a second gear 7 is installed after the bottom of the fixed shaft 6 passes through the support frame 4, a third gear 8 is installed at the bottom of the support frame 4 and close to the three second gears 7, a connecting rod 9 is installed at the bottom of the third gear 8, a stirring rod 10 is installed at the bottom of the connecting rod 9 away from the third gear 8, multiple sets of stirring blades 11 are installed on the outer ring surface of the stirring rod 10, a catalytic box 12 is installed at the bottom of the homogenizing cylinder 1, a fixed pipe 13 is installed at one end of the bottom inner wall of the catalytic box 12, and several component flow pipes 14 are installed at equal intervals on the outside of the fixed pipe 13.
[0026] Reference Figure 1 - Figure 5 The outer gear ring 2 meshes with the three sets of first gears 5. When the stirring motor 3 drives the support frame 4 to rotate, the three sets of first gears 5 rotate synchronously outside the outer gear ring 2. The outer ring surface of the fixed shaft 6 is rotatably connected to the inside of the support frame 4. The second gear 7 and the third gear 8 mesh with each other. The top of the third gear 8 is rotatably connected to the bottom of the support frame 4, and the bottom of the third gear 8 is fixedly connected to the connecting rod 9. When the stirring motor 3 drives the support frame 4 to rotate, it synchronously drives the three sets of stirring rods 10 and stirring blades 11 at the bottom to stir and homogenize the internal material. The first gear 5 rotates synchronously along the outer gear ring 2 and drives the second gear 7 to rotate through the fixed shaft 6. Since the second gear 7 and the third gear 8 mesh with each other and synchronously drive the third gear 8 to rotate, the third gear 8 rotates through the connecting rod 9 and drives the single set of stirring rods 10 and stirring blades 11 to rotate. Thus, while the three sets of stirring rods 10 rotate along the support frame 4, the single stirring rod 10 rotates synchronously along the connecting rod 9, thereby increasing the efficiency of stirring and homogenization.
[0027] Reference Figure 1 - Figure 3A gas pump 15 is installed at one end of the catalytic converter 12, and the output end of the gas pump 15 extends into the interior of the catalytic converter 12 and is connected to the fixed pipe 13. Exhaust holes 1201 are symmetrically opened on both sides of the top end of the catalytic converter 12. Several sets of gas outlet holes 1401 are opened on the diversion pipe 14. The gas pump 15 injects gas into the fixed pipe 13 and enters the interior of the diversion pipe 14. The micropore design of the gas outlet hole 1401 allows the gas to be released in the form of microbubbles, increasing the gas-liquid contact area and promoting the rate of catalytic reaction. At the same time, it avoids side reactions caused by excessive local concentration. The exhaust hole 1201 at the top of the catalytic converter 12 is used to maintain the pressure balance inside the converter and discharge reaction byproducts. The exhaust hole 1201 is collected and processed by connecting to external equipment.
[0028] Reference Figure 1 - Figure 3 The homogenizing cylinder 1 has a feed inlet 16 installed at one end of its top and a discharge outlet 17 installed at the bottom of its inner side. The homogenizing cylinder 1 is connected to the catalytic tank 12 through the discharge outlet 17. The catalytic tank 12 has an outlet 18 installed at the outer end away from the air pump 15. The material enters the homogenizing cylinder 1 from the feed inlet 16, is homogenized by the stirring blades 11, and then flows into the catalytic tank 12 through the discharge outlet 17. After the catalytic reaction is completed, the material is discharged from the discharge outlet 18. Solenoid valves are installed on the outside of both the discharge outlet 17 and the discharge outlet 18 to facilitate the control of the discharge.
[0029] The implementation principle of the multi-layer structure catalytic efficiency enhancement device in this application embodiment is as follows: When the device is used, when the stirring motor 3 drives the support frame 4 to rotate, it synchronously drives the three sets of stirring rods 10 and stirring blades 11 at the bottom to stir and homogenize the internal material. Simultaneously, the first gear 5 rotates along the outer gear ring 2, driving the second gear 7 to rotate via the fixed shaft 6. Since the second gear 7 and the third gear 8 mesh with each other, they synchronously drive the third gear 8 to rotate. When the third gear 8 rotates, it drives the individual stirring rods 10 and stirring blades 11 to rotate via the connecting rod 9. Thus, while the three sets of stirring rods 10 rotate along the support frame 4, each individual stirring rod 10 rotates synchronously along the connecting rod 9, thereby increasing the stirring efficiency. The material enters the homogenization cylinder 1 through the feed inlet 16, is homogenized by the stirring blades 11, and then flows into the catalytic tank 12 through the discharge port 17. The gas pump 15 injects gas into the fixed pipe 13 and into the inside of the diversion pipe 14. The micropore design of the gas outlet 1401 allows the gas to be released in the form of microbubbles, increasing the gas-liquid contact area and improving the gas utilization rate, thus promoting the rate of catalytic reaction. At the same time, it avoids side reactions caused by excessively high local concentrations. The exhaust port 1201 at the top of the catalytic tank 12 is used to maintain the pressure balance inside the tank and discharge the reaction byproducts. The exhaust port 1201 is connected to external equipment for collection and treatment. After the catalytic reaction is completed, the material is discharged from the discharge port 18. The operation is convenient and effectively improves its catalytic efficiency.
