Description

Technical Field

[0001] This utility model relates to the field of solid waste pyrolysis technology, specifically to a solid waste pyrolysis treatment device. Background Technology

[0002] Solid waste refers to solid or semi-solid substances generated in production, daily life, and other activities that have lost their original value or have been discarded even if they have not lost their value. Its harm is mainly reflected in three core aspects: environmental pollution, health threats, and resource waste. Large-scale accumulation of solid waste will occupy arable land and forest land, leading to soil hardening and loss of planting capacity. Heavy metals (such as lead and mercury) and toxic chemicals in waste will seep into the soil, causing soil pollution that is difficult to remediate.

[0003] Solid waste treatment includes pyrolysis, which involves heating solid waste in an oxygen-free or low-oxygen environment to break it down into usable gaseous, liquid, or solid products.

[0004] However, existing solid waste pyrolysis treatment equipment still suffers from low processing efficiency and high energy consumption, and needs further improvement and optimization. Utility Model Content

[0005] The purpose of this invention is to provide a solid waste pyrolysis treatment device that can perform precise zoned treatment of solid waste, thereby significantly improving treatment efficiency and energy utilization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A solid waste pyrolysis treatment device includes a horizontally extending and fan-shaped pyrolysis flow pipe, a circulation drive ring arranged coaxially with the pyrolysis flow pipe, and multiple pyrolysis partition plates fixed on the circulation drive ring. The thermal pyrolysis flow pipe is divided into a drying section, a core thermal pyrolysis section, and a carbonization section from the thermal pyrolysis input end to the thermal pyrolysis output end. Drying heat-conducting pipes are wound around the outer side of the drying section; The pyrolysis flow pipe is fixed on a supporting base plate, and the circulation drive ring is driven to rotate by a motor fixed on the supporting base plate through gear ring transmission.

[0007] Preferably, the drying section is provided with multiple pyrolysis input pipes connected to its interior near the pyrolysis input end, and the drying section is provided with multiple drying exhaust pipes connected to its interior near the core pyrolysis section.

[0008] Explanation: Combustion exhaust gas is introduced into the drying heat pipe, and the residual heat of the combustion exhaust gas is used to heat and dry the solid waste inside the drying section. The water vapor and other gases generated during the heating and drying of the solid waste will be discharged from the drying exhaust pipe.

[0009] Preferably, a hot cracking high-temperature containment shell is provided around the core pyrolysis section, and multiple combustion gas supply pipes are fixed on the side wall of the hot cracking high-temperature containment shell. A combustion nozzle is provided at one end of the combustion gas supply pipe inside the hot cracking high-temperature containment shell. The hot cracking high temperature containment shell has multiple air supply pipes connected to its interior on its lower side, and multiple exhaust pipes connected to its interior on its upper side. The core pyrolysis section is equipped with a pyrolysis liquid discharge pipe connected to its interior, which extends to the outside of the pyrolysis high-temperature containment shell.

[0010] Explanation: The fuel gas is ejected from the combustion nozzle and burned. The combustion flame heats the core pyrolysis section, causing the solid waste to undergo pyrolysis at a certain temperature. The small molecule gases produced by pyrolysis, such as methane, ethane, and liquid oil vapor, will be discharged from the pyrolysis liquid outlet pipe and stored in a tank for easy recycling.

[0011] Preferably, the carbonization section is surrounded by a carbonization insulation shell, and the carbonization insulation shell is provided with a carbonization insulation inlet pipe that communicates with its interior. The carbonization insulation inlet pipe is connected to each exhaust gas outlet pipe. The carbonized insulation shell is equipped with a carbonized insulation output pipe that is connected to its interior. The carbonized insulation output pipe is connected to one end of the drying heat conduction pipe.

[0012] Explanation: The solid residue remaining after the pyrolysis treatment of solid waste will enter the carbonization section for carbonization treatment to generate high-purity carbon black; the high-temperature combustion exhaust gas discharged from the exhaust pipe will then be introduced into the carbonization insulation shell through the carbonization insulation input pipe, and the combustion exhaust gas will exchange heat with the carbonization section to carbonize the solid residue inside the carbonization section.

[0013] Preferably, the gap between the thermal decomposition input end and the thermal decomposition output end forms an external driving space, and the support base plate is provided with a circulating driving mechanism for driving the circulating driving ring to move. The circulating driving mechanism includes two concentrically arranged circulating driving slide rails fixed on the support base plate, and the circulating driving slide rails are concentrically arranged with the circulating driving ring. The two cyclic drive slide rails are located inside and outside the external drive space, respectively; Multiple cyclic drive sliders are slidably connected on the cyclic drive slide rail. A clamping support ring is fixed on the cyclic drive slider. The axis of the clamping support ring extends radially along the cyclic drive ring. A clamping support column is slidably connected inside the clamping support ring. A clamping claw is fixed at one end of the clamping support column near the external drive space. The clamping claw is a C-shaped claw. A clamping drive fixed cylinder is fixed on the clamping support ring. The circumference of the clamping drive fixed cylinder is parallel to the axis of the clamping support ring. A clamping drive sliding cylinder is slidably connected in the clamping drive fixed cylinder. The outer end of the clamping drive sliding cylinder is fixedly connected to the end of the clamping support column away from the clamping claw. The clamping drive fixed cylinder is equipped with a clamping drive rod for driving the clamping drive sliding cylinder to extend and retract.

[0014] Explanation: The cyclic drive slider will move counterclockwise and clockwise periodically along the cyclic drive slide rail. The counterclockwise movement is the driving stroke, and the clockwise movement is the reset stroke. By using the cyclic drive slider to perform the driving stroke and reset stroke repeatedly, the cyclic drive ring, each pyrolysis partition plate, and the solid waste loaded between the pyrolysis partition plates will continuously and intermittently move counterclockwise around the pyrolysis flow pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects: 1. The present invention has a reasonable structural design and its core advantage lies in the combination of precise zoned processing, tiered utilization of heat and dynamic material conveying, which greatly improves processing efficiency and energy utilization. 2. This utility model is easy to operate. It clearly divides the pyrolysis flow pipe into three functional areas: a drying section, a core pyrolysis section, and a carbonization section. Each area is designed with a specific treatment structure to achieve precise adaptation to the entire waste treatment process. 3. The equipment of this utility model constructs a heat circulation system of "core section exhaust gas → carbonization section insulation → drying section heating", realizing the efficient secondary utilization of energy; 4. The circulating drive mechanism of this utility model drives the circulating drive ring and the thermal pyrolysis partition plate to move, so that the waste can be dynamically transported in the fan-shaped thermal pyrolysis flow pipe, effectively avoiding material accumulation.

[0023] Example 2: Based on Example 1, such as Figure 2 As shown, the gap between the thermal decomposition input end 101 and the thermal decomposition output end 102 forms an external driving space 106. The support base plate 13 is provided with a circulating driving mechanism 20 for driving the circulating driving ring 11 to move. The circulating driving mechanism 20 includes two concentrically arranged circulating driving slide rails 21 fixed on the support base plate 13. The circulating driving slide rails 21 and the circulating driving ring 11 are concentrically arranged. The two cyclic drive slide rails 21 are located inside and outside the external drive space 106, respectively; like Figure 5 As shown, multiple circulating drive sliders 22 are slidably connected on the circulating drive slide rail 21. A clamping support ring 23 is fixed on the circulating drive slider 22. The axis of the clamping support ring 23 extends radially along the circulating drive ring 11.

[0024] In practical applications, this utility model is used to... Figure 2 For reference, the circulating drive ring 11 rotates counterclockwise under the drive of the circulating drive mechanism 20. The circulating drive ring 11 then drives each pyrolysis partition plate 12 to move together. The solid waste to be pyrolyzed is loaded between two adjacent pyrolysis partition plates 12. The solid waste is dried, pyrolyzed and carbonized in the drying section 103, the core pyrolysis section 104 and the carbonization section 105 in sequence. Drying process: Solid waste to be pyrolyzed is fed into the drying section 103 through each pyrolysis input pipe 1031 via a spiral solid conveyor. Combustion exhaust gas is introduced into the drying heat conduction pipe 1030, and the waste heat of the combustion exhaust gas is used to heat and dry the solid waste inside the drying section 103. The water vapor and other gases generated by heating and drying the solid waste will be discharged from the drying exhaust pipe 1032. The drying exhaust gas discharged from the drying exhaust pipe 1032 can be treated to render it harmless using existing gas purification equipment. Thermal decomposition treatment: After drying, the solid waste then enters the core pyrolysis section 104, and fuel gas is introduced into each combustion gas supply pipe 1042. The fuel gas is sprayed out from the combustion nozzle 1043 for combustion. The combustion flame heats the core pyrolysis section 104, causing the solid waste to undergo pyrolysis at 550°C. The small molecule gases produced by pyrolysis, such as methane, ethane and liquid oil vapor, will be discharged from the pyrolysis liquid discharge pipe 1040 and stored in tanks for easy recycling. An air conveyor using existing technology continuously supplies air into the hot cracking high-temperature containment shell 1041 through an air conveying pipe 1044 to maintain the complete combustion of the fuel gas; The combustion exhaust gas generated after combustion heating will be discharged from the exhaust pipe 1045; Carbonization treatment: The solid residue remaining after the pyrolysis treatment of solid waste will enter the carbonization section 105 for carbonization treatment to generate high-purity carbon black. The high-temperature combustion exhaust gas discharged from the exhaust pipe 1045 is then input into the interior of the carbonization insulation shell 1051 through the carbonization insulation input pipe 1052. The combustion exhaust gas exchanges heat with the carbonization section 105, thereby carbonizing the solid residue inside the carbonization section 105. After heat exchange inside the carbonized insulation shell 1051, the combustion exhaust gas is finally discharged from the carbonized insulation output pipe 1053 and transported to the drying heat conduction pipe 1030, where the residual heat of the combustion exhaust gas is used for drying. The combustion exhaust gas discharged from the other end of the drying heat pipe 1030 is also treated to be harmless using existing gas purification equipment before being discharged. In the working process of the cyclic drive mechanism 20, the cyclic drive slider 22 is driven by a servo motor of existing technology through gear ring transmission along the cyclic drive slide rail 21. Since the cyclic drive slide rail 21 is an arc shape arranged concentrically with the cyclic drive ring 11, Figure 2 For reference, the cyclically driven slider 22 will move counterclockwise and clockwise periodically along the cyclically driven slide rail 21. The counterclockwise movement is the driving stroke, and the clockwise movement is the reset stroke. At the initial position of the drive stroke, the inner rod of the clamping drive rod 243 retracts, causing the clamping drive sliding cylinder 242, the clamping support column 231 and the clamping claw 232 to move towards the pyrolysis partition plate 12, so that the C-shaped clamping claw 232 engages with the edge of the pyrolysis partition plate 12, thereby causing the circulating drive slider 22 to drive the pyrolysis partition plate 12 together with the circulating drive ring 11 and the other pyrolysis partition plates 12 to move counterclockwise. After the distance between two adjacent pyrolysis partition plates 12 is moved, the cyclic drive slider 22 stops, and the inner rod of the clamping drive rod 243 extends to drive the clamping drive sliding cylinder 242, the clamping support column 231 and the clamping claw 232 to move away from the pyrolysis partition plate 12, so that the C-shaped clamping claw 232 is disengaged from the pyrolysis partition plate 12. Subsequently, the cyclic drive slider 22 moves clockwise to complete the reset stroke, returning to the initial position of the drive stroke, and the cyclic drive slider 22 repeats the above movement process. At the position of the external drive space 106, the cyclic drive slider 22 is used to repeatedly perform the drive stroke and reset stroke, thereby driving the cyclic drive ring 11, each pyrolysis partition plate 12, and the solid waste loaded between the pyrolysis partition plates 12 to continuously and intermittently move counterclockwise around the pyrolysis flow pipe 10.
