Description

Technical Field

[0001] This invention relates to the technical field of chemical catalysis, and more particularly to a single-atom catalytic device. Background Technology

[0002] In the field of chemical catalysis, single-atom catalysis has attracted much attention due to its high activity and high selectivity. Single-atom catalysis is a novel catalytic technology whose core lies in uniformly dispersing metal atoms in an isolated state on a support material, allowing each metal atom to participate in the catalytic reaction as an independent active center. However, in practical applications, traditional catalytic devices often suffer from some problems that limit the effectiveness of single-atom catalysis.

[0003] Chinese utility model patent CN216377624U discloses a wastewater treatment device based on a cobalt-iron bimetallic single-atom catalyst, including a hollow support and a wastewater treatment tank located above the hollow support. The bottom of the wastewater treatment tank is fixedly connected to a support rod via a support plate, and a lifting plate is movably installed inside the hollow support. Although this device can achieve a full reaction between the catalyst and the wastewater, greatly promoting the depth of mixing between the catalyst and the wastewater, material tends to accumulate on the inner wall and bottom of the catalytic reactor during use. This problem not only directly reduces the catalytic efficiency but also significantly increases the difficulty of subsequent cleaning of the catalytic reactor.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a single-atom catalytic device is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a single-atom catalytic device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a single-atom catalytic device, comprising: a catalytic vessel, a catalytic mechanism disposed within the catalytic vessel, and a hot gas pipe disposed within the catalytic vessel;

[0007] The catalytic mechanism includes a motor, a connecting plate disposed at one end of the output shaft of the motor, a plurality of inner wall scrapers disposed on the outer circumference of the connecting plate, a connecting ring disposed at the bottom of the plurality of inner wall scrapers, and a plurality of bottom scrapers disposed on the inner circumference of the connecting ring, with a connecting cylinder provided between the plurality of bottom scrapers.

[0008] One end of the hot gas pipe passes through the catalytic reactor and is rotatably connected to the bottom of the connecting plate. Several through-holes are opened on the outer circumference of the hot gas pipe.

[0009] In a preferred embodiment of this utility model, the motor is fixedly connected to the upper surface of the catalytic reactor, and the top of the connecting plate is rotatably connected to the bottom inner wall of the catalytic reactor.

[0010] In a preferred embodiment of this utility model, one end of the motor output shaft passes through the catalytic reactor and is fixedly connected to the top of the connecting plate.

[0011] In a preferred embodiment of this utility model, one end of each of the plurality of inner wall scrapers is fixedly connected to the outer circumferential wall of the connecting plate, and the outer circumferential wall of the plurality of inner wall scrapers is in close contact with the inner circumferential wall of the catalytic reactor.

[0012] In a preferred embodiment of this utility model, the bottom of each of the plurality of inner wall scrapers is fixedly connected to the outer circumferential wall of the connecting ring, and a stirring plate is fixedly connected to the inner circumferential wall of each of the plurality of inner wall scrapers.

[0013] In a preferred embodiment of this utility model, the inner circumferential wall of the connecting cylinder is rotatably connected to the outer circumferential wall of the hot air pipe.

[0014] In a preferred embodiment of this utility model, one end of each of the plurality of bottom scrapers is fixedly connected to the inner circumferential wall of the connecting ring, and the other end of each of the plurality of bottom scrapers is fixedly connected to the outer circumferential wall of the connecting cylinder.

[0015] In a preferred embodiment of this invention, the bottom of several of the bottom scrapers is in close contact with the bottom inner wall of the catalytic reactor.

[0016] In a preferred embodiment of this invention, the top pipe of the catalytic reactor is connected to a feed hopper.

[0017] In a preferred embodiment of this invention, the bottom pipe of the catalytic reactor is connected to a discharge pipe.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] This invention provides a single-atom catalytic device. By driving a connecting plate and several inner wall scrapers and bottom scrapers on it to rotate via a motor, it not only achieves thorough stirring of the reactants in the catalytic reactor, promoting uniform contact between the single-atom catalyst and the reactants and improving catalytic efficiency, but also allows a hot gas pipe to pass through the catalytic reactor and rotate to connect to the bottom of the connecting plate. Several gas outlets on its outer circumference can uniformly release hot gas into the catalytic reactor, achieving uniform heating of the reactants and further improving the speed and uniformity of the catalytic reaction.

[0020] This invention provides a single-atom catalytic device. The inner wall scraper and the bottom scraper are closely attached to the inner wall and bottom of the catalytic reactor. As the motor rotates, the inner wall scraper and the bottom scraper can effectively scrape off the material attached to the inner wall and bottom of the catalytic reactor, preventing the problem of reduced catalytic efficiency and cleaning difficulties caused by material sticking to the wall. This not only improves the utilization rate of the catalytic reactor, but also reduces the frequency and difficulty of manual cleaning. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] like Figure 1 As shown, a single-atom catalytic device includes: a catalytic vessel 1, a catalytic mechanism 2 disposed within the catalytic vessel 1, and a hot gas pipe 4 disposed within the catalytic vessel 1;

[0027] like Figures 1-2 As shown, the catalytic mechanism 2 includes a motor 201, a connecting plate 202 disposed at one end of the output shaft of the motor 201, a plurality of inner wall scrapers 203 disposed on the outer circumference of the connecting plate 202, a connecting ring 205 disposed at the bottom of the plurality of inner wall scrapers 203, and a plurality of bottom scrapers 206 disposed on the inner circumference of the connecting ring 205, and a connecting cylinder 207 disposed between the plurality of bottom scrapers 206.

[0028] One end of the hot gas pipe 4 passes through the catalytic reactor 1 and is rotatably connected to the bottom of the connecting plate 202. Several through-holes 6 are opened on the outer circumference of the hot gas pipe 4. The motor 201 is fixedly connected to the upper surface of the catalytic reactor 1. The top of the connecting plate 202 is rotatably connected to the bottom inner wall of the catalytic reactor 1. One end of the output shaft of the motor 201 passes through the catalytic reactor 1 and is fixedly connected to the top of the connecting plate 202.

[0029] One end of each of the inner wall scrapers 203 is fixedly connected to the outer circumferential wall of the connecting plate 202. The outer circumferential wall of each of the inner wall scrapers 203 is tightly fitted to the inner circumferential wall of the catalytic reactor 1. The bottom of each of the inner wall scrapers 203 is fixedly connected to the outer circumferential wall of the connecting ring 205. A stirring plate 204 is fixedly connected to the inner circumferential wall of each of the inner wall scrapers 203. One end of each of the bottom scrapers 206 is fixedly connected to the inner circumferential wall of the connecting ring 205. The other end of each of the bottom scrapers 206 is fixedly connected to the outer circumferential wall of the connecting cylinder 207. The bottom of each of the bottom scrapers 206 is tightly fitted to the inner bottom wall of the catalytic reactor 1.

[0030] The top pipe of the catalytic reactor 1 is connected to the feed hopper 3, and the bottom pipe of the catalytic reactor 1 is connected to the discharge pipe 5.

[0031] It should be noted that the motor 201 drives the connecting plate 202 and its several inner wall scrapers 203 and stirring plates 204 to rotate, effectively achieving the stirring and mixing of the reactants in the catalytic reactor 1. The inner wall scrapers 203 are in close contact with the inner circumference of the catalytic reactor 1, ensuring uniform distribution of the material in the reactor and improving catalytic efficiency. Simultaneously, the stirring plates 204 further enhance the stirring effect, allowing the single-atom catalyst to contact the reactants more fully, thereby accelerating the catalytic reaction process. Furthermore, the inner wall scrapers 203 and the bottom scraper 206 work together to effectively prevent material deposition on the inner wall and bottom of the catalytic reactor 1 during stirring, and also automatically clean the catalytic reactor 1 after stirring. The bottom of the bottom scraper 206 is in close contact with the bottom inner wall of the catalytic reactor 1, ensuring thorough removal of deposited material and avoiding the problems of decreased catalytic efficiency and difficulty in cleaning the catalytic reactor 1 caused by material deposition. The feed hopper 3 facilitates the addition of reactants; the discharge pipe 5 facilitates the discharge of materials after the catalytic reaction.

[0032] In use, the reactants are added through the feed hopper 3 at the top of the catalytic reactor 1. Then, the motor 201 is started, causing its output shaft to rotate the connecting plate 202. Several inner wall scrapers 203 are fixedly connected to the outer circumference of the connecting plate 202. Therefore, the rotation of the connecting plate 202 causes these inner wall scrapers 203 to rotate together within the catalytic reactor 1. A stirring plate 204 is fixedly connected to the inner circumference of each inner wall scraper 203. Thus, the rotation of the inner wall scrapers 203 also causes the stirring plate 204 to stir within the catalytic reactor 1. The outer circumference of the inner wall scrapers 203 is in close contact with the inner circumference of the catalytic reactor 1. As they rotate, they scrape and stir the reactants within the catalytic reactor 1, ensuring uniform distribution of the materials. The stirring plate 204 further enhances the stirring effect, allowing the single-atom catalyst to come into more complete contact with the reactants. Meanwhile, one end of the hot gas pipe 4 passes through the catalytic reactor 1 and is rotatably connected to the bottom of the connecting plate 202. Several through-holes 6 are formed on the outer circumference of the hot gas pipe 4. Hot gas is evenly released into the catalytic reactor 1 through these outlets 6, providing the necessary heat for the catalytic reaction. During stirring, the inner wall scraper 203 scrapes the inner wall of the catalytic reactor 1 to prevent material from depositing on the inner wall. The bottom scraper 206 is in close contact with the bottom inner wall of the catalytic reactor 1, and as the connecting plate 202 rotates, they scrape the bottom to prevent material from depositing at the bottom. After the catalytic reaction is complete, the material after the catalytic reaction can be easily discharged through the discharge pipe 5 at the bottom of the catalytic reactor 1.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
