Abstract
Description
Technical Field
[0001] This invention relates to the field of pyrolysis equipment technology, and in particular to a pyrolysis equipment for preparing combustible gases from organic waste liquid. Background Technology
[0002] Pyrolysis refers to the process by which solid waste is decomposed into substances such as fuel gas and fuel oil under anaerobic or oxygen-deficient conditions at high temperatures. Many inorganic and organic substances will undergo decomposition reactions when heated to a certain degree. Pyrolysis equipment is an important piece of equipment in the field of waste treatment. It decomposes organic substances by heating them to high temperatures under anaerobic or oxygen-deficient conditions. Pyrolysis equipment can not only effectively transform waste, but also realize the recycling and reuse of resources.
[0003] In existing technologies, organic waste liquid will naturally deposit due to gravity during the pyrolysis process, resulting in only the surface layer of waste liquid being able to contact the hot wall. This limits the pyrolysis reaction to a local area, causing low heat transfer efficiency and uneven pyrolysis rate.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0032] The pyrolysis device for preparing combustible gas from organic waste liquid disclosed in this invention is mainly applied to scenarios in which, due to gravity-induced natural deposition, only the surface layer of waste liquid can contact the hot wall, resulting in uneven heating.
[0033] Reference Figures 1-7 A pyrolysis device for preparing combustible gas from organic waste liquid includes an inner cylinder 1;
[0034] Outer cylinder 2 is fixedly connected to the outside of inner cylinder 1;
[0035] Liquid inlet pipe 7 is located at the top of the inner cylinder 1;
[0036] Valve 8 is installed on the inlet pipe 7;
[0037] Liquid outlet pipe 9 is located at the bottom of the inner cylinder 1;
[0038] Valve 210 is installed on the liquid outlet pipe 9;
[0039] Partition plate 4, both partition plates 4 are fixedly connected to the inner wall of the inner cylinder 1;
[0040] The operation module 5 is located on the inner cylinder 1. The operation module 5 includes multiple sliding chambers 501, which are fixedly connected to the bottom inner wall of the inner cylinder 1 and the top of the two partition plates 4. Multiple piston parts 507 are slidably connected to the inner walls of the multiple sliding chambers 501. A sliding part 508 is fixedly connected to one side of each piston part 507. A push plate part 506 is fixedly connected to the end of each sliding part 508 away from the piston part 507. The operation module 5 continuously agitates the waste liquid and pushes the waste liquid towards the high-temperature inner wall of the inner cylinder 1.
[0041] Reference Figure 1 , Figure 3 and Figure 4 The working module 5 also includes a rotating rod 502, and a rotating hole is provided at the bottom of the inner cylinder 1. The rotating rod 502 is rotatably connected in the rotating hole. Multiple winding wheels 509 are fixedly connected at equal intervals to the outside of the rotating rod 502. Multiple winding ropes 510 are wrapped around the outside of the multiple winding wheels 509. The ends of the multiple winding ropes 510 away from the winding wheels 509 are fixedly connected to one side of the corresponding piston component 507. Springs 511 are wrapped around the outside of the multiple winding ropes 510. One end of the multiple springs 511 is fixedly connected to the corresponding piston component 507. The ends of the multiple springs 511 away from the piston component 507 are fixedly connected to the inner wall of the corresponding sliding chamber 501.
[0042] Reference Figure 1 , Figure 3 and Figure 4 Each of the multiple sliding chambers 501 has a fixed ring frame 503 fixedly connected to its top. Each of the multiple fixed ring frames 503 has multiple slots equidistantly spaced around its circumference. Each of the multiple slots has a fixed mounting sleeve 504 fixedly connected to its inner wall. Each of the multiple mounting sleeves 504 has a sliding rod 505 slidably connected to its inner wall. Each of the multiple sliding rods 505 is fixedly connected to one side of the corresponding push plate 506.
[0043] Reference Figure 1 , Figure 5 and Figure 6 The lower end of the rotating rod 502 is fixedly connected to a gear 515, and the bottom of the inner cylinder 1 is fixedly connected to a rotating frame 512. A swinging member 513 is movably connected to the rotating frame 512. A toothed ring 516 is fixedly connected to one side of the swinging member 513. The toothed ring 516 meshes with the gear 515.
[0044] Reference Figure 1 , Figure 5 and Figure 6 The swing member 513 has a sliding groove, and a sliding connector 519 is slidably connected in the sliding groove.
[0045] Reference Figure 1 , Figure 5 and Figure 6A drive motor 514 is fixedly connected to the bottom of the inner cylinder 1. A rotating disk 517 is fixedly connected to the output end of the drive motor 514. A thin rod is fixedly connected to the top of the rotating disk 517. A connecting rod 518 is movably connected to the outside of the thin rod, and the end of the connecting rod 518 away from the rotating disk 517 is movably connected to the sliding connector 519.
[0046] In a specific application scenario, the drive motor 514 is started to rotate the rotating disk 517. This, via the connecting rod 518, causes the sliding connecting piece 519 to slide within the sliding slot on the swinging piece 513. This forces the swinging piece to drive the gear ring 516 to swing back and forth. Through the meshing of the gear ring 516 and the gear 515, the rotating rod 502 is driven to rotate back and forth. At this time, the winding wheel 509 is driven by the rotating rod 502, continuously tightening and loosening the winding rope 510. This causes the piston 507 to slide back and forth under the elastic action of the spring 511, driving the pusher through the sliding piece 508. Plate 506 continuously agitates the organic waste liquid and pushes it towards the high-temperature inner wall of the inner cylinder 1, achieving dynamic stirring and pushing of the organic waste liquid during the pyrolysis process. This allows the organic waste liquid to circulate during pyrolysis, enhancing heat transfer efficiency. At the same time, it can prevent the waste liquid from forming a low-temperature accumulation layer due to gravity deposition. By continuously pushing the waste liquid towards the high-temperature inner wall, it ensures that most of the waste liquid has multiple contacts with the heat source, which not only accelerates the pyrolysis reaction and shortens the overall pyrolysis time, but also reduces coking or carbonization caused by local overheating through homogenized heating, thereby improving the pyrolysis speed and production stability.
[0047] Reference Figure 1 , Figure 2 and Figure 7 An auxiliary module 6 is provided on the inner wall of the outer cylinder 2, and the auxiliary module 6 includes a mounting ring frame 601. Multiple mounting holes are equidistantly provided on the mounting ring frame 601. A rotating shaft 602 is rotatably connected in each of the multiple mounting holes, and a fan blade 603 is fixedly connected to the bottom end of each of the multiple rotating shafts 602.
[0048] Reference Figure 1 , Figure 2 and Figure 7 The auxiliary module 6 also includes a rotating ring frame 605, which is located above the mounting ring frame 601. The rotating ring frame 605 is movably connected to the inner wall of the outer cylinder 2. A gear ring 606 is fixedly connected to the rotating ring frame 605, and a gear 604 is fixedly connected to the top of each of the multiple rotating shafts 602. The multiple gears 604 mesh with the gear ring 606.
[0049] Reference Figure 1 , Figure 2 and Figure 7 A general-purpose motor 607 is fixedly connected to the inner wall of the outer cylinder 2, and a gear 608 is fixedly connected to the output end of the general-purpose motor 607. The gear 608 meshes with the gear ring 606.
[0050] Reference Figure 1 and Figure 2 The outer cylinder 2 has a fixing hole, and a heating tube 3 is fixedly connected in the fixing hole. The top of the inner cylinder 1 has a round hole, and an air outlet pipe 11 is fixedly connected in the round hole. A valve 12 is installed on the air outlet pipe 11.
[0051] In specific application scenarios, the general-purpose motor 607 is started to rotate the gear 608. Through the meshing of the gear 608 and the gear ring 606, the rotating ring frame 605 is driven to rotate. Then, through the meshing of the gear ring 606 with the gear 604, the rotating shaft 602 is driven to rotate. Through the fan blades 603, some of the high-temperature gas at the bottom of the outer cylinder 2 is pumped to the top, so that the outer cylinder 2 forms a longitudinal temperature gradient from top to bottom. This allows the organic waste liquid to undergo step-by-step heating and pyrolysis during the gravity fall, which not only achieves the step-by-step decomposition of components with different boiling points, but also reduces heat loss.
[0052] Working principle: Keep valves 10 and 12 closed, open valve 8 to send organic waste liquid into the inner cylinder 1 through the inlet pipe 7. The organic waste liquid falls under gravity, and the descent speed is slowed by the partition plate 4 to ensure the heating time of the organic waste liquid in each stage in the inner cylinder 1. At the same time, high-temperature gas is sent into the outer cylinder 2 through the heating pipe 3 to heat and pyrolyze the organic waste liquid in the inner cylinder 1. Start the drive motor 514 to rotate the rotating disk 517, which drives the sliding connecting rod 518. The receiving part 519 slides into the sliding groove on the swinging part 513, forcing the swinging part to drive the gear ring 516 to swing back and forth. Through the meshing of the gear ring 516 and the gear 515, the rotating rod 502 is driven to rotate back and forth. At this time, the winding wheel 509 is driven by the rotating rod 502 to continuously tighten and loosen the winding rope 510, causing the piston part 507 to slide back and forth under the elastic action of the spring 511. Through the sliding part 508, the push plate part 506 continuously agitates the organic waste liquid and pushes it towards the high temperature of the inner cylinder 1. The inner wall dynamically stirs and propels the organic waste liquid during pyrolysis, ensuring its circulation and enhancing heat transfer efficiency. It also prevents the formation of a low-temperature deposit due to gravity sedimentation. By continuously pushing the waste liquid towards the high-temperature inner wall, it ensures that most of the waste liquid makes multiple contacts with the heat source, accelerating the pyrolysis reaction, shortening the overall pyrolysis time, and reducing coking or carbonization caused by localized overheating through homogenized heating, thus improving pyrolysis speed and production stability. The system starts the general-purpose motor 607 and rotates the gear 608. The meshing of gear 3 608 and gear ring 2 606 drives the rotating ring frame 605 to rotate, which in turn drives gear 2 604 to rotate through gear ring 2 606, causing the rotating shaft 602 to rotate. The fan blades 603 draw some of the high-temperature gas from the bottom of the outer cylinder 2 to the top, creating a longitudinal temperature gradient from top to bottom in the outer cylinder 2. This allows the organic waste liquid to undergo stepwise heating and pyrolysis during gravity fall, achieving the stepwise decomposition of components with different boiling points and reducing heat loss. The produced combustible gas is collected through the gas outlet pipe 11.
