Description

Technical Field

[0001] This invention relates to the field of hazardous waste treatment technology, specifically to a hazardous waste treatment device. Background Technology

[0002] With industrial development, the amount of hazardous waste emitted during industrial production processes is increasing. It is estimated that the world generates 330 million tons of hazardous waste annually. Hazardous waste is characterized by corrosiveness, reactivity, flammability, toxicity, and infectiousness. Due to the serious pollution and potential impacts caused by hazardous waste, its treatment is becoming increasingly important. Hazardous waste refers to waste that poses a real or potential hazard to human health or the environment, or waste that is listed in the National Hazardous Waste List or identified as having hazardous characteristics according to the national hazardous waste identification standards and methods.

[0003] Hazardous waste disposal methods mainly include physical, physicochemical, and biological methods. Physical methods include: for solid waste (residue), common physical treatment processes include compaction, crushing, and sorting; for liquid waste (liquid waste), common physical treatment processes include: sedimentation, flotation, centrifugation, filtration, and distillation. Physicochemical methods for treating hazardous waste include: for solid waste, thermal treatment (incineration, pyrolysis) and solidification / stabilization; for liquid waste, coagulation, chemical precipitation, acid-base neutralization, oxidation-reduction, adsorption and desorption, ion exchange, and incineration. Biological methods are only applicable to organic waste. For organic solid waste, these include composting and anaerobic fermentation; for organic liquid waste, these include activated sludge and anaerobic digestion.

[0004] Rotary kilns are commonly used for the thermal treatment of hazardous waste. Incineration effectively destroys toxic and harmful hazardous waste, making it the fastest and most effective technology for reducing and rendering hazardous waste harmless. However, when using a rotary kiln to treat hazardous waste, some wastes with high salt content decompose at high temperatures. The decomposed elements recombine at high temperatures to form some low-melting-point salts. These low-melting-point salts are very viscous at high temperatures and can adhere to and bind other substances, forming coke inside the rotary kiln. The formation of coke increases the energy consumption of the rotary kiln combustion. Furthermore, subsequent manual cleaning of the inner wall of the rotary kiln is quite difficult. Therefore, we propose a hazardous waste treatment device. Summary of the Invention

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-17This invention provides a technical solution: a hazardous waste treatment device. This invention addresses the technical problems in the background art by making corresponding improvements, including a rotary kiln 1, a support body 2 installed on one side of the rotary kiln 1 (both the support body 2 and the rotary kiln 1 are fixedly connected to a supporting surface), wherein a feed hopper 3 is fixedly installed on the support body 2, and a conveying pipe 4 is fixedly connected between the feed hopper 3 and the rotary kiln 1. A crushing device 5 is installed on the support body 2, and the discharge end of the crushing device 5 is in communication with the interior of the feed hopper 3. The crushing device 5 in this invention is existing technology. Its main body consists of a crushing zone and a sealed chamber. The sealed chamber is filled with nitrogen. When the oxygen content in the sealed chamber is low, the material is transported to the crushing zone for crushing. Pipes A6 and B7 are fixedly installed on the feed hopper 3. Pipe A6 is used to transport waste with high salt content, and pipe B7 is used to transport substances with high melting points. Pipes C8 and D9 are located below pipes A6 and B7 (both pipes C8 and D9 are fixedly connected to the feed hopper 3). Pipe C... Pipe 8 is used to transport waste containing potassium or sodium, and pipe D9 is used to transport waste with high halogen content. Further explanation is that the coking issue in rotary kiln 1 when processing hazardous waste is mainly due to the following: During the incineration process, hazardous waste decomposes at high temperatures, and the decomposed elements recombine at high temperatures to form some low-melting-point salts. These low-melting-point salts are very viscous at high temperatures and can self-adhere and adhere to other substances, forming coke within rotary kiln 1. This type of coking is difficult to remove. To avoid or reduce this type of coking... The occurrence of coking is generally addressed by incinerating waste containing sodium, potassium, and other components at different times during the feeding process, and by mixing waste with other wastes, such as adding substances with high melting points like lime, before incineration. In order to solve the coking problem, this invention specifically designs the feeding hopper 3. It should be noted that the feeding hopper 3 should also be equipped with inlets for other wastes. Since this is not closely related to this invention, it is not described in detail here.

[0039] Furthermore, the present invention provides baffles 10 on one side of pipes A 6, B 7, C 8, and D 9, and force-bearing components 11 are also provided on the baffles 10. As a further limitation of the present invention, the force-bearing components 11 include connecting seats 111 fixedly installed on the baffles 10, and rollers 112 rotatably connected to the inner wall of the connecting seats 111 are rotatably installed on the connecting seats 111. A slot 113 is provided on one side of the connecting seats 111, and a telescopic column 114 slidably connected to the inner wall of the connecting seats 114 is provided inside the slot 113. Limiting seats 115 are fixedly installed on both sides of pipes A 6, B 7, C 8, and D 9, and guide columns 116 are fixedly installed on the limiting seats 115. Seat bodies 116 slidably connected to the guide columns 116 are fixedly installed on both sides of the baffles 10. 17. A return spring 118 is also connected between the seat 117 and the limiting seat 115. A tube 6, B tube 7, C tube 8 and D tube 9 are each provided with a snap-fit ​​groove 16 that is slidably connected to the end of the telescopic column 114. The snap-fit ​​groove 16 is composed of an output area 161, an upward tilting area 162, a snap-fit ​​area 163, a reciprocating area 164 and multiple guide blocks 165. One guide block 165 is located at the intersection of the output area 161 and the upward tilting area 162, and another guide block 165 is located at the intersection of the upward tilting area 162 and the snap-fit ​​area 163. To further explain, in the initial state, multiple baffles 10 are located at the outlet positions of A tube 6, B tube 7, C tube 8 and D tube 9, that is, they obstruct the discharge of A tube 6, B tube 7, C tube 8 and D tube 9.

[0040] Further explanation: The present invention includes a drive disc frame 12 and a drive disc frame 2 13 arranged parallel to each other inside the feed hopper 3. Drive disc frame 12 is located above drive disc frame 2 13, corresponding to pipes A 6 and B 7, and drive disc frame 2 13 corresponds to pipes C 8 and D 9. Both drive disc frames 12 and 2 13 are equipped with functional members 14. Further description: the functional member 14 in the present invention includes an arc-shaped protrusion 141 fixedly installed on drive disc frame 12, and multiple arc-shaped protrusions 141 are installed at equal angles on drive disc frame 12. For ease of description, the present invention... Two arc-shaped protrusions 141 are installed on the frame 12, and the angle difference between the two arc-shaped protrusions 141 is 60°. To further explain, in this invention, the angle difference between tube A 6 and tube B 7 is 90°, wherein the rollers 112 on tube A 6 and tube B 7 are located on the movement trajectory of the arc-shaped protrusions 141. Two arc-shaped protrusions 142 are fixedly installed on the drive disc frame 13, and the angle difference between the two arc-shaped protrusions 142 is 60°. To further explain, in this invention, the angle difference between tube C 8 and tube D 9 is 90°, wherein the rollers 112 on tube C 8 and tube D 9 are located on the movement trajectory of the arc-shaped protrusions 142.

[0041] The feeding hopper 3 is equipped with a power component 15, which controls the drive disc frame 12 or drive disc frame 2 13 to perform directional movements. As a further limitation of the present invention, the power component 15 includes a servo motor 151 fixedly installed on the feeding hopper 3, and a rotating shaft 152 is fixedly installed on the output end of the servo motor 151. A force-applying disc 153 (located above drive disc frame 12, which is located above drive disc frame 2 13) is slidably installed on the rotating shaft 152 and slidably connected to its inner wall. An actuating sleeve 154 is fixedly installed on one side of the force-applying disc 153, and an actuating block 155 is fixedly installed on the actuating sleeve 154. A force-receiving block 121 is fixedly installed on drive disc frame 12. Furthermore, a force-receiving block 131 is fixedly installed on the drive disc frame 13, wherein a force-receiving block 121 is located above the force-receiving block 131, and an action block 155 is located above the force-receiving block 121. Multiple arc-shaped magnet blocks 156 are fixedly installed on the side of the force-applying disc 153 away from the action sleeve 154. A fixed sleeve 17 is fixedly installed on the inner wall of the feed hopper 3, and a magnetic disc 171 rotatably connected to the fixed sleeve 17 is rotatably installed on the fixed sleeve 17. A telescopic rod 172 is installed on the magnetic disc 171, and the end of the telescopic rod 172 is connected to one side of the force-applying disc 153. An arc-shaped electromagnet assembly 173 is installed on the magnetic disc 171, and the arc-shaped electromagnet assembly 173 generates a repulsive force on the arc-shaped magnet blocks 156 when energized.

[0042] Further, when incinerating low-melting-point, high-salt hazardous waste in batches, the incineration volume needs to be strictly controlled. Simultaneously, a certain amount of high-melting-point substances such as lime needs to be added. Only when the combined materials reach a certain content can the coking rate be effectively reduced. Therefore, this invention addresses this by slidably installing a rubber disc 18 inside the feed hopper 3, which is slidably connected to its inner wall. A connecting shaft 181 is fixedly installed on one side of the rubber disc 18. Positioning columns 182 are rotatably connected to the connecting shaft 181 near both ends. A connecting sleeve 183 is fixedly installed on the inner wall of the feed hopper 3, and the ends of the positioning columns 182 are located inside the connecting sleeve 183 and slidably connected to its inner wall. The ends of the positioning columns 182 are flush with the top inner wall of the connecting sleeve 183. A spring body 184 is connected between the feed chamber 3 and a button body 185 is installed at the bottom of the connecting sleeve 183. A touch button 186 is fixedly installed on the inner wall of the feed chamber 3. The touch button 186 is connected to the servo motor 151 by an electrical signal. The touch button 186 is located on the movement trajectory of one end of the connecting shaft 181. A drive motor 187 is installed outside the feed chamber 3. The output end of the drive motor 187 passes through the feed chamber 3 and extends into its interior. The button body 185 is connected to the drive motor 187 by an electrical signal. The end of the connecting shaft 181 is a protrusion 188. The output end of the drive motor 187 is provided with a groove 189 that matches the protrusion 188 of the connecting shaft 181. It should be noted that the servo motor 151 in this invention is controlled by a central control device.

[0043] Specifically, when staff need to process waste with high salt content, the arc-shaped electromagnet assembly 173 is energized via the central control system, with a current of M (the other current is represented by N, where N is greater than M). The energized arc-shaped electromagnet assembly 173 generates a repulsive force on the arc-shaped magnet block 156. Under the action of the telescopic rod 172, the force-applying disc 153 and its actuating sleeve 154 are positioned on the rotating shaft 152. Specifically, the actuating block 155 on the actuating sleeve 154 moves towards the force-receiving block 121 (initially, the actuating block 155 is above the force-receiving block 121). When the arc-shaped electromagnet assembly 173 is energized (with a current of M), the actuating block 155 moves onto the trajectory of the force-receiving block 121. When the actuating block 155 rotates with the actuating sleeve 154, it acts on the force-receiving block 121. Simultaneously, the servo motor 151 starts, and its output drives the rotating shaft 152 to rotate. During the rotation of the rotating shaft 152, the force-applying disk 153 and the actuating sleeve 154 are slidably connected on the rotating shaft 152, causing the force-applying disk 153 and the actuating sleeve 154 to rotate with the rotating shaft 152 (and under the action of the telescopic rod 172, the magnetic disk 171 rotates on the fixed sleeve 17). When the actuating block 155 on the actuating sleeve 154 rotates with the actuating sleeve 154, it acts on the force-receiving block 121. The force-receiving block 121 is acted upon, causing the drive disc frame 12 to rotate inside the feed bin 3, driving... Two arc-shaped protrusions 141 on the tray 12 move synchronously. During rotation, the arc-shaped protrusion 141 closer to pipe A 6 acts on the roller 112 corresponding to pipe A 6. The roller 112, under the force of the arc-shaped protrusion 141 and the action of the connecting seat 111, drives the baffle 10 to move outward (i.e., the outlet of pipe A 6 opens). At this time, waste material in pipe A 6 enters the feed hopper 3. During the movement of the baffle 10, the seats 117 on both sides stretch the return spring 118. When the protruding area of ​​one of the arc-shaped protrusions 141 acts on the roller 112, the telescopic column 114 on it is located at the end of the output area 161. When the protruding area of ​​one of the arc-shaped protrusions 141 no longer acts on the roller 112... Under the action of the return spring 118, the telescopic column 114 enters and is confined within the locking area 163. Furthermore, one guide block 165 is located at the intersection of the output area 161 and the upwardly inclined area 162. One side of this guide block 165 is a right-angled surface (i.e., the side closer to the end of the output area 161), and the other side is an inclined surface (i.e., the side away from the end of the output area 161). The other guide block 165 is located at the intersection of the upwardly inclined area 162 and the locking area 163. The side closer to the locking area 163 is a right-angled surface, and the side away from the locking area 163 is an inclined surface. Furthermore, when the servo motor 151 starts, it rotates 90° (the angle difference between the two arc-shaped protrusions 141 is 60°). After the servo motor 151 rotates 90°...The roller 112 corresponding to pipe A 6 is located between two arc-shaped protrusions 141. At this time, the baffle 10 corresponding to pipe A 6 no longer obstructs its outlet, and the material flows out. Meanwhile, the baffle 10 corresponding to pipe B 7 still obstructs its outlet, and the waste in pipe A 6 enters the feed hopper 3.

[0044] The material falls onto the rubber disc 18, which obstructs the material. Simultaneously, the rubber disc 18 descends under gravity. During this descent, if the connecting shaft 181 on the rubber disc 18 moves to the touch button 186 (and applies force to the touch button 186), it indicates that the high-salt waste has reached a certain level, requiring the addition of high-melting-point substances such as lime. The touch button 186 sends a signal to the servo motor 151, which then rotates another 90°, thus driving the process. As the tray 12 continues to rotate, the second arc-shaped protrusion 141 first acts on the roller 112 corresponding to tube A 6. The roller 112, under the force, drives the baffle 10 to move outwards. At this time, the end of the telescopic column 114 on it moves from the locking area 163 to the reciprocating area 164. Under the action of the return spring 118, the baffle 10 returns to its initial position, thus obstructing the outlet of tube A 6. The first arc-shaped protrusion 141 then acts on the roller 112 corresponding to tube B 7. 12. The same action as above: the outlet of pipe B7 opens, and the material enters the feed hopper 3 from within. The rubber disc 18 descends. When the end of the positioning column 182 touches the button body 185, the servo motor 151 starts first, rotating 180° to return to the initial state. The second arc-shaped protrusion 141 acts on the roller 112 corresponding to pipe B7 during the movement. The specific process is the same as the closing action of the outlet of pipe A6. At this time, the outlets of both pipe A6 and pipe B7 are closed, and then the drive motor... When 187 is started, further, when the end of the positioning column 182 touches the button body 185, one end (i.e., the protrusion) of the connecting shaft 181 moves into the groove 189 of the output end of the drive motor 187, and the drive motor 187 rotates 90°, so that the rubber disc 18 rotates 90° in the feed bin 3 (the area in which the rubber disc 18 rotates in the feed bin 3 has an inner diameter larger than the inner diameter of the rubber disc 18), that is, it no longer obstructs the material, and the mixed material enters the rotary kiln 1 for incineration.

[0045] If the staff needs to process waste containing sodium, potassium, or other components, or waste with high halogen content, the current flow of the arc-shaped electromagnet group 173 is increased (i.e., the current flow is N). The action block 155 on the action sleeve 154 leaves the area of ​​the first force block 121 and enters the area of ​​the second force block 131. The servo motor 151 starts 90°, and its output end drives the rotating shaft 152 to rotate. The action block acts on the second force block 131, and the force block 131 is subjected to the action force to drive the second drive plate frame 13 to rotate. When the second drive plate frame 13 rotates, the two arc-shaped protrusions 142 on it move synchronously with it. The specific operation is the same as the movement of the first drive plate frame 12. Thus, through the structural design of the present invention, the coking rate of the rotary kiln 1 is effectively reduced.
