[0036] Further, liquid distribution assembly 5 further includes slide 56, two mounting seats 55 are fixedly installed on the inner wall of tank body 1, slide 56 is vertically slidably connected on two mounting seats 55, slide 56 is provided with ball ring, first spray head 54 is hinged with first connecting rod 58, annular chute 57 is arranged on rotating shaft 51, the ball ring of slide 56 is sleeved on rotating shaft 51, ball is arranged in ball ring, ball is slidably connected with annular chute 57, a plurality of first connecting rods 58 are hinged with ball ring, when rotating shaft 51 rotates, slide 56 is driven to reciprocate up and down by the cooperation of annular chute 57 and ball ring, when slide 56 reciprocates up and down, a plurality of first spray heads 54 are driven to swing reciprocally by a plurality of first connecting rods 58, so that a plurality of first spray heads 54 can also swing reciprocally in the process of rotation, thereby the spraying range of first spray head 54 is expanded, the situation that spraying blind area appears in tank body 1 is avoided, the distribution of catalyst in tank body 1 is more uniform, thereby the efficiency of gas-liquid contact is improved.

[0037] In addition, the packing assembly 6 is used to promote gas-liquid contact. The packing assembly 6 includes a material rack 61, which is fixedly connected to the slide 56. Multiple packing strings 62 are fixedly installed on the material rack 61. When the slide 56 moves up and down, the multiple packing strings 62 are driven to move up and down through the material rack 61. A layer of catalyst can be attached to the surface of the packing strings 62, thereby increasing the contact area between the catalyst and the gas.

[0038] In addition, the packing assembly 6 also includes two swing rods 63, which are respectively hinged to two mounting bases 55. The ends of the swing rods 63 away from the mounting bases 55 are fixedly connected to arc-shaped rods 64. Two second connecting rods 65 are hinged to the slide 56, and the ends of the two second connecting rods 65 away from the slide 56 are respectively hinged to the two swing rods 63. The two arc-shaped rods 64 are mirror images of each other. When the two arc-shaped rods 64 move, they drive multiple packing strings 62 to swing. When the slide 56 moves up and down, it drives the two swing rods 63 to swing back and forth through the two second connecting rods 65. During the movement, the two arc-shaped rods 64 can continuously contact multiple packing strings 62, thereby driving multiple packing strings 62 to shake continuously. This allows multiple packing strings 62 to continue to shake during the up and down reciprocating movement, so that the catalyst attached to the surface of the packing strings 62 can come into contact with the gas during the continuous movement, further increasing the contact area between the catalyst and the gas and ensuring the efficiency of gas-liquid contact.

[0039] It is worth noting that when the atomizing component 7 and the liquid distribution component 5 are running, the atomizing component 7 atomizes the catalyst flowing on the inner wall of the tank 1. The atomizing component 7 includes an annular cover 71, which is fixedly connected to the inner wall of the tank 1. An adsorption ring 72 is fixedly connected to the inner side of the annular cover 71. A rebound ring 73 is connected to the bottom of the annular cover 71 through multiple springs. Multiple hammers 76 are fixedly connected to the side of the rebound ring 73 near the annular cover 71. Two sliding shafts 74 are fixedly connected to the rebound ring 73. An arc toothed ring 75 is fixedly connected to the outer wall of the rotating shaft 51. The arc toothed ring 75 has two arc-shaped teeth. When the sliding shaft 74 moves, it slides and contacts the two arc-shaped teeth in turn. Every half turn of the arc toothed ring 75 can first drive the rebound ring 73 to move down through the two sliding shafts 74. The adsorption ring 72 is reset by elastic force. Multiple fine holes are opened on the adsorption ring 72. The catalyst flowing on the inner wall of the tank 1 flows along the annular cover 71 to the adsorption ring 72. The multiple fine holes on the adsorption ring 72 have a certain adsorption capacity. The adsorption ring 72 can adsorb the catalyst flowing on the inner wall of the tank 1. The adsorption ring 72 is made of elastic material. When the rebound ring 73 rebounds and resets, multiple hammers 76 strike the adsorption ring 72 during movement. The adsorption ring 72 vibrates after being impacted, thereby ejecting the catalyst adsorbed inside the adsorption ring 72. The catalyst is shaken out in a mist form. After the catalyst is shaken into a mist form, it can make efficient contact with the gas again, improving the utilization rate of the catalyst. A pipe is set at the bottom of the tank 1 to discharge the catalyst deposited in the tank 1 for recycling.

[0040] It is worth noting that multiple air bladders 77 are connected between the rebound ring 73 and the annular cover 71. Second nozzles 78 are fixedly connected to the air bladders 77 and penetrate the annular cover 71. When the rebound ring 73 rebounds, it squeezes the multiple air bladders 77. After being squeezed, the multiple air bladders 77 eject gas through the multiple second nozzles 78. The multiple second nozzles 78 are aimed above the adsorption ring 72. Therefore, after a mist of catalyst is formed above the adsorption ring 72, the multiple second nozzles 78 eject air, so that multiple fine airflows are formed above the adsorption ring 72, thereby promoting the contact efficiency between the gas and the catalyst.

[0041] Using the above structure, the working principle of this case is as follows: gas enters tank 1 through inlet pipe 2. When the gas enters tank 1 through inlet pipe 2, it drives the rotating shaft 51 to rotate via impeller 52. The rotation of shaft 51 drives the liquid pan 53 to rotate, and the liquid pan 53 drives multiple first nozzles 54 to rotate. The catalyst enters the liquid pan 53 through inlet pipe 4. The liquid pan 53 delivers the catalyst to the multiple first nozzles 54 through multiple hoses. During the rotation, the multiple first nozzles 54 spray the catalyst into tank 1. The gas flows from bottom to top inside tank 1, and the spiral guide plate 8 can guide the flow, causing the gas to form a swirling flow. After the gas reaches the top of the tank 1, it is discharged from the gas outlet pipe 3. The gas comes into contact with the catalyst inside the tank 1. When the rotating shaft 51 rotates, it drives the slide 56 to move up and down in a reciprocating motion through the cooperation of the annular inclined groove 57 and the ball ring. When the slide 56 moves up and down in a reciprocating motion, it drives the multiple first nozzles 54 to swing back and forth through multiple first connecting rods 58. This allows the multiple first nozzles 54 to swing back and forth during the rotation, thereby expanding the spray range of the first nozzles 54 and avoiding the occurrence of spray blind spots in the tank 1. This makes the catalyst distribution in the tank 1 more uniform, thereby improving the efficiency of gas-liquid contact.

[0042] A catalyst layer can be attached to the surface of the packing string 62, thereby increasing the contact area between the catalyst and the gas. When the slide 56 moves up and down, it drives multiple packing strings 62 to move up and down through the material rack 61. When the slide 56 moves up and down, it can also drive two swing rods 63 to swing back and forth through two second connecting rods 65. The two swing rods 63 drive two arc rods 64 to swing back and forth. During the movement, the two arc rods 64 can continuously contact multiple packing strings 62, thereby causing multiple packing strings 62 to shake continuously. This allows multiple packing strings 62 to shake continuously during the up and down reciprocating movement, so that the catalyst attached to the surface of the packing string 62 can contact the gas during the continuous movement, further increasing the contact area between the catalyst and the gas and ensuring the efficiency of gas-liquid contact.

[0043] After some catalyst contacts the inner wall of tank 1, it flows downwards along the inner wall. This part of the catalyst has poor contact with the gas. The catalyst flowing along the inner wall of tank 1 flows along the annular cover 71 to the adsorption ring 72. The multiple fine pores on the adsorption ring 72 have a certain adsorption capacity. The adsorption ring 72 can adsorb the catalyst flowing along the inner wall of tank 1. When the rotating shaft 51 rotates, it drives the arc tooth ring 75 to rotate. During the rotation of the arc tooth ring 75, the two arc teeth alternately contact the two sliding shafts 74. The two arc teeth are centrally symmetrically arranged and have arc surfaces and vertical surfaces. During the contact between the sliding shaft 74 and the arc teeth, the sliding shaft 74 first slides down along the arc surface of the arc teeth. At the same time, the two sliding shafts 74 drive the spring ring 73 to move downwards. The multiple springs between the spring ring 73 and the annular cover 71 are stretched. At this time, the multiple springs apply an upward elastic force to the spring ring 73. When the sliding shaft 74 disengages from the arc surface, the spring ring 73 rebounds and resets using the elastic force of multiple springs, and the sliding shaft 74 also resets, allowing the sliding shaft 74 to contact another arc surface again. Every half-turn of the arc tooth ring 75 can first drive the spring ring 73 downward through the two sliding shafts 74, and then the spring ring 73 resets using elastic force. When the spring ring 73 rebounds and resets, the multiple hammers 76 on the spring ring 73 strike the adsorption ring 72. The adsorption ring 72 vibrates after being struck, causing the catalyst adsorbed inside the adsorption ring 72 to be ejected, and the catalyst is shaken out in a mist form, thereby achieving the effect of re-atomizing the catalyst flowing on the inner wall of the tank 1. After the catalyst is shaken into a mist, it can make efficient contact with the gas again, improving the utilization rate of the catalyst. A pipe is provided at the bottom of the tank 1 to discharge the catalyst deposited in the tank 1 for recycling.

[0044] As the rebound ring 73 rebounds, it compresses multiple air bladders 77. After being compressed, the multiple air bladders 77 eject gas through multiple second nozzles 78. The multiple second nozzles 78 are aligned with the adsorption ring 72. Therefore, after a mist of catalyst is formed above the adsorption ring 72, the multiple second nozzles 78 eject air, causing multiple fine airflows to form above the adsorption ring 72, thereby promoting the contact efficiency between the gas and the catalyst.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
