Description

Technical Field

[0001] The invention relates to the technical field of solid waste treatment, and in particular to a plasma waste treatment device. Background Art

[0002] With the acceleration of industrialization and urbanization, the types and quantities of waste are increasing year by year, especially the treatment needs of industrial waste, domestic waste and hazardous waste are becoming more and more urgent. How to achieve the harmlessness, reduction and resource utilization of waste has become a core technical issue in the field of modern waste management. Although traditional waste treatment methods, such as landfill, incineration and physical and chemical treatment, have alleviated the problem of waste accumulation to a certain extent, these methods have many shortcomings, such as land occupation, secondary pollution and low resource utilization. Plasma waste treatment technology has gradually become an important research direction in the field of waste treatment due to its ultra-high temperature, high energy density and high purity of the reaction environment.

[0003] Solid waste is crushed to a suitable particle size, liquid waste needs to be evenly injected by pumping, and waste particles enter the treatment chamber through a conveying device (such as a screw conveyor, a sealed feeder). The plasma generator in the equipment forms plasma in the treatment chamber through arc discharge, electromagnetic induction or microwave excitation. Organic waste undergoes pyrolysis under high temperature conditions to generate small molecule gases, and metals and other inorganic components are melted and cooled to form inert solid residues.

[0004] Plasma treatment relies on high temperatures to decompose and transform waste. When the wet waste has a high water content, most of the energy is used to evaporate the water, rather than for the actual thermal cracking and chemical reaction of the waste. This not only increases the energy consumption of the equipment, but also significantly reduces the efficiency of plasma energy utilization. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] refer to Figure 1-Figure 9 , a plasma waste treatment device, comprising:

[0045] Treatment tank 100;

[0046] A plasma generator 101 is provided on the treatment tank 100, one end of which extends into the treatment tank 100;

[0047] A cover plate 102 is arranged on the top of the treatment tank body 100, and a preheating material box 103 is arranged on the cover plate 102;

[0048] A screening plate 104 is arranged in the preheating material box 103, and a plurality of screening openings 105 are opened on the screening plate 104. An adjusting plate 106 is slidably connected in the screening plate 104, and an adjusting opening 107 communicating with the screening openings 105 is opened on the adjusting plate 106;

[0049] A plurality of preheating pipes 108 are arranged in the preheating material box 103, a preheating channel is formed between every two preheating pipes 108, and an air supply port 109 connected to the preheating channel is opened on the outer wall of the preheating pipe 108;

[0050] The air supply component provided between the preheating pipe 108 and the treatment tank 100 is used to extract the exhaust gas in the treatment tank 100 and transport it to the preheating pipe 108;

[0051] The vibrating screen component is provided between the preheating material box 103 and the screening plate 104, and is used to vibrate the screening plate 104 up and down. The vibrating screen component can move the adjustment plate 106 by a preset distance every time the screening plate 104 is vibrated up and down to a preset number of times, so as to increase the area of ​​the adjustment port 107 communicating with the screening port 105;

[0052] The vibrating screen component can also intermittently open the cover plate 102 when vibrating the screening plate 104 up and down, so as to put the waste materials into the treatment tank 100;

[0053] By setting up a preheating box 103, solid waste can be crushed into particles and then placed in the preheating box 103, and the plasma generator 101 is started. The electrodes in the generator are supplied with high-frequency alternating current, direct current or radio frequency electricity through a power supply to form a strong electric field or magnetic field. This electric field accelerates the movement of electrons, causing gas molecules to collide. Under the action of a strong electric field, high-speed moving electrons collide inelastically with gas molecules, and gas molecules are ionized after obtaining sufficient energy to form charged particles (positive ions and electrons). At this time, the gas is converted into a plasma state, and a high-temperature and high-energy-density plasma state is maintained in the discharge zone by continuous power supply. A high temperature gradually forms in the treatment tank 100. Specifically, the air supply component can be started, and the air supply component transports a part of the hot gas in the treatment tank 100 to the preheating pipe 108, and blows it to the preheating channel through the air supply port 109. At this time, the vibrating screen component can be started. Since the waste particles generated when the solid waste is pre-crushed are of different sizes, in the initial state, the regulating port 107 on the regulating plate 106 only overlaps a small part with the screening port 105 to form a small-caliber screen. When the vibrating screen component is working, the screening plate 104 and the regulating plate 106 vibrate up and down, and the particles with a diameter smaller than the overlapping diameter of the screening port 105 and the regulating port 107 in the waste particles will fall into the preheating channel below, while the particles with a larger diameter will be blocked by the screening plate 104. When the particles pass through the preheating channel, the high-temperature gas in the preheating pipe 108 is blown into the preheating channel through the air supply port 109, fully contacting the particles, and quickly heating the surface of the particles. The high-temperature gas can not only effectively evaporate the moisture on the surface of the particles, but also increase the overall temperature of the particles to a certain level, providing thermal support for subsequent high-temperature treatment. When the vibrating screen component is working, the cover 102 can be opened intermittently, and the preheated particles fall into the treatment tank 100 under gravity and directly contact the high-temperature plasma in the treatment tank 100. The high-energy field provided by the plasma quickly decomposes the organic components in the particles into simple gaseous substances, such as hydrogen (H 2) and carbon monoxide (CO), while the inorganic components melt into inert slag under high temperature. The gaseous products can be sent into the preheating pipe 108 by the air supply component to participate in the preheating of the exhaust gas particles. Finally, the exhaust gas treatment system can be connected to the preheating material box 103, and the exhaust gas treatment system purifies the trace harmful components in the gaseous products. The vibrating screen component moves the adjustment plate 106 by a preset distance every time the screening plate 104 is vibrated up and down to a preset number of times, so as to increase the area of ​​the adjustment port 107 connected to the screening port 105, thereby gradually adjusting the screening capacity of the screening plate 104, so that more particles with larger diameters can also pass through the overlapping area of ​​the screening port 105 and the adjustment port 107. This design ensures that during the vibrating screen process, small particles can first fall into the preheating channel for preheating, and as the screening time increases, the gradually enlarged screening port 105 will allow larger particles of waste to pass through, ensuring that all particles can complete the screening and preheating operations in sequence. This dynamically adjusted screening method can not only achieve accurate screening according to the particle size distribution, but also avoid the problem of screen blockage and improve the screening efficiency. In addition, during the movement of the adjustment plate 106, the vibration of the vibrating screen component can avoid the accumulation of particles, further improving the stability and continuity of the system. The preheated particles gradually enter the bottom of the preheating channel through gravity, and finally fall evenly into the treatment tank 100 through the intermittent delivery function of the vibrating screen component. Since the particles have been graded, screened and fully preheated, they can quickly adapt to the high temperature environment of the plasma after entering the treatment tank 100, thereby achieving rapid decomposition or melting, optimizing the processing efficiency and reducing energy consumption. The combination of dynamic screening and adjustment mechanism provides flexibility for the equipment when processing wastes of different particle sizes and characteristics. In addition, allowing the cover plate 102 to be opened intermittently can not only ensure that the particles fall into the treatment tank 100 as needed, but also reduce the loss of high-temperature gas in the treatment tank 100 to a certain extent, thereby effectively preserving the internal heat. This design avoids the problem of heat loss caused by opening the cover 102 normally, and further improves the thermal efficiency and overall energy utilization of the equipment. Through the intermittent operation of the cover 102, the preheated particles can enter the treatment tank 100 in batches and evenly, ensuring the continuity and stability of the plasma high temperature treatment. At the same time, the high temperature environment inside the tank is maintained, which not only reduces the additional energy consumption of the plasma device, but also shortens the time required to treat each batch of waste, and improves the treatment efficiency. It is worth noting that the small particles are preheated first, and the preheating time is sufficient to quickly reach the required temperature. During this process, a part of the hot gas blown out from the preheating pipe 108 may pass through the screening port 105 and the regulating port 107 to enter the top of the screening plate 104. During this process, a part of the hot gas blown out from the preheating pipe 108 will pass through the screening port 105 and the regulating port 107 to enter the top of the screening plate 104 and contact with the unscreened particles.Providing preliminary heating for these particles reduces the heating time after they enter the preheating channel, and improves the overall preheating efficiency. In addition, grading by size makes preheating more targeted. Preheating large particles will not hinder the full heating of small particles, avoiding the situation where heat is concentrated in a certain part and wasted. After the particles are graded, preheating is gradually completed, and there is no need to provide high heat support for all particles at one time. This step-by-step preheating method can reduce the energy consumption of high-temperature heating and reduce operating costs. The graded screening and preheating method can adapt to wastes with different particle distributions, and shows higher adaptability when facing wastes with complex components or large variations in particle size, which expands the application range of the equipment.

[0054] As a further solution of the present invention, the air supply component includes a connecting pipe 200 connected to the treatment tank 100, the upper part of the connecting pipe 200 is connected to the preheating pipe 108, and the connecting pipe 200 is provided with an exhaust fan 201, the exhaust end of the exhaust fan 201 is connected to the lower part of the connecting pipe 200, and the air outlet end of the exhaust fan 201 is connected to the upper part of the connecting pipe 200;

[0055] By setting the exhaust fan 201, when in use, the exhaust fan 201 can be used to extract the hot gas in the tank and transport it to the preheating pipe 108 to form a hot air flow, so that the gas temperature in the preheating pipe 108 is maintained at a high level. These hot air flows can effectively heat the waste particles entering the preheating channel, increase their surface temperature, and quickly evaporate the moisture on the surface of the particles, providing the required thermal energy support for subsequent plasma treatment.

[0056] As a further solution of the present invention, the vibrating screen component includes a connecting shaft 300 rotatably connected to the preheating material box 103, a connecting plate 301 is connected to the connecting shaft 300, an arc-shaped slide rail 302 is provided on the connecting plate 301, a support rod 303 is slidably connected to one side of the preheating material box 103, a connecting rod 304 connected to the adjustment plate 106 is slidably connected to the support rod 303, and the top of the connecting rod 304 is slidably connected to the arc-shaped slide rail 302;

[0057] By setting the connecting shaft 300, when in use, the connecting shaft 300 can be rotated. The rotation of the connecting shaft 300 can make the connecting disk 301 rotate. The rotation of the connecting disk 301 can make the connecting rod 304 move up and down along the rotation trajectory of the arc-shaped slide rail 302 through the limiting effect between the arc-shaped slide rail 302 and the connecting rod 304. When the connecting rod 304 moves up and down, it can drive the screening plate 104 to move up and down, thereby achieving the purpose of screening the waste particles.

[0058] As a further solution of the present invention, the vibrating screen component also includes a connecting frame 305 connected to one side of the preheating material box 103, one end of the connecting shaft 300 is rotatably connected to the connecting frame 305, the connecting plate 301 is slidably connected to the connecting shaft 300, one side of the connecting frame 305 is connected to a limiting frame 306, a movable boss 307 is slidably connected to the limiting frame 306, the movable boss 307 is rotatably connected to the connecting shaft 300, the limiting frame 306 is also slidably connected to a top contact table 308, and the top contact table 308 is threadedly connected to a reciprocating screw a309 rotatably connected to the limiting frame 306;

[0059] By setting a reciprocating screw a309, when the screening plate 104 moves up and down to a preset number of times, the reciprocating screw a309 can be rotated to move the top contact platform 308 downward, compress the movable boss 307 and change its position, so that the movable boss 307 drives the connecting plate 301 and the connecting rod 304 to move a distance to the right. The movement of the connecting rod 304 directly drives the adjustment plate 106 to shift, thereby increasing the overlapping area of ​​the adjustment port 107 and the screening port 105. Through this design, the vibrating screen component can dynamically adjust the size of the screening port 105, so that particles of the next diameter can pass through the screening port 105 smoothly, ensuring the flexibility and efficiency of the screening process and achieving the purpose of graded screening. At the same time, it can also effectively reduce the risk of screen blockage.

[0060] As a further solution of the present invention, the vibrating screen component also includes a gear a400 rotatably connected to the connecting shaft 300, the gear a400 is an incomplete gear, a reciprocating screw b401 is rotatably connected to the connecting frame 305, a gear b402 adapted to the gear a400 is connected to the reciprocating screw b401, a rack 403 slidably connected to the connecting frame 305 is threadedly connected to the reciprocating screw b401, and a gear c404 meshing with the rack 403 is connected to the reciprocating screw a309;

[0061] By setting the gear a400, when the connecting shaft 300 rotates, the gear b402 can be rotated through the gear a400. When the gear b402 rotates, the rack 403 can slide through the reciprocating screw b401. When the rack 403 is engaged with the gear c404 on the reciprocating screw a309, the reciprocating screw a309 can be rotated, so that the top contact platform 308 can press the moving boss 307 downward to change the position of the moving boss 307.

[0062] As a further solution of the present invention, a ratchet mechanism 405 is provided between the gear c404 and the reciprocating screw a309;

[0063] By setting the ratchet mechanism 405, when the connecting shaft 300 has not rotated one circle, the reciprocating screw b401 can be rotated a preset number of times through the gear a400 and the gear b402, and the rack 403 can be moved a certain distance. Every time the rack 403 passes through the gear c404, the gear c404 can be rotated and the reciprocating screw a309 can be rotated through the ratchet mechanism 405, and the position of the top contact platform 308 can be displaced downward. When the rack 403b moves to the extreme position along the reciprocating screw b401, the rack 403 starts to move back to the original position. When it passes through the gear c404 again, the gear c404 rotates and the reciprocating screw a309 does not rotate, thereby achieving the purpose of adjusting the caliber size of the screening port 105 after the screening plate 104 moves up and down multiple times. The caliber of the screening port 105 is adjusted after multiple vibration cycles, so that the particulate matter in the preheating box 103 can be fully screened. In specific applications, the pitch of the reciprocating screw b401 can be selected as needed to control the specific number of "multiple times" mentioned above.

[0064] As a further solution of the present invention, a reset disk 406 is rotatably connected to one side of the connection disk 301, and a spring a407 is connected between the reset disk 406 and the connection frame 305;

[0065] By setting the spring a407, the spring a407 can be compressed after the connection disk 301 is displaced. After the reciprocating screw a309 rotates to move the top contact table 308 downward to the limit position, the reciprocating screw a309 continues to rotate, allowing the top contact table 308 to gradually return upward. At this time, the spring a407 releases potential energy to allow the connection disk 301 to gradually return to its original position, ready for the next waste treatment work.

[0066] As a further solution of the present invention, a plurality of rotating shafts 500 are rotatably connected to the cover plate 102, a baffle 501 is connected to the rotating shaft 500, a chain transmission mechanism a502 is provided between every two adjacent rotating shafts 500, and a spring b503 is provided between the rotating shaft 500 and the cover plate 102;

[0067] By setting a baffle 501, the setting of multiple baffles 501 can close the cover plate 102. When the cover plate 102 is opened to release the preheated particles, one of the rotating shafts 500 can be rotated to allow the multiple rotating shafts 500 and the baffle 501 to rotate synchronously through the chain transmission mechanism a502 to form a material drop channel, and the preheated particles can fall into the treatment tank body 100.

[0068] As a further solution of the present invention, a gear d504 is rotatably connected to the connecting frame 305, and a chain transmission mechanism b505 is provided between the gear d504 and one of the rotating shafts 500;

[0069] By setting the gear d504, the gear d504 can rotate a preset angle every time the connecting shaft 300 rotates one circle, and the rotating shaft 500 can rotate a preset angle through the chain transmission mechanism b505, thereby achieving the purpose of intermittent opening and closing of the cover 102.
