Description

Technical Field

[0001] The invention relates to the technical field of carbonization and incineration of garbage, in particular to a high-temperature dry distillation and carbonization incineration device for domestic garbage. Background Art

[0002] Waste incineration is a waste treatment method that achieves reduction, harmlessness and resource utilization by burning waste at high temperatures. During the incineration process, the combustible components in the waste react with oxygen at high temperatures to produce harmless or low-harm substances such as carbon dioxide and water vapor, while releasing heat, which can be used for power generation or heating. The volume of ash after incineration is greatly reduced, which is convenient for subsequent treatment or landfill. However, waste incineration also needs to pay attention to flue gas purification to prevent the emission of harmful substances such as dioxins and ensure the environmental friendliness of the treatment process.

[0003] However, the existing garbage is usually incinerated and carbonized in the same operating environment for multiple stages, and is always in the same chamber from combustion to carbonization. The processing environment in the same chamber cannot meet the optimal conditions for combustion and carbonization at the same time, resulting in limited processing efficiency. For example, combustion requires sufficient oxygen and high temperature, while carbonization may require different temperature and atmosphere conditions. Moreover, when the garbage is put into the combustion chamber, the garbage accumulates due to the rapid feeding, and the accumulated garbage will cause incomplete combustion of the garbage. When the garbage is not burned fully, a large amount of black smoke and harmful gases will be generated, such as dioxins and other highly toxic substances, which are extremely harmful to the environment and human health.

[0004] In addition, the existing garbage incineration carbonization equipment is manually filled with garbage when it is put in, and the operator is required to use tools or manually to put the garbage into the combustion chamber during filling. The internal temperature of the combustion chamber is extremely high when working, and the operator needs to face high temperature roasting and heat radiation, which can easily cause burns, heat stroke and other occupational injuries. At the same time, manual filling requires frequent opening of the feed port, which causes the temperature of the combustion chamber to fluctuate, affecting the pyrolysis gasification efficiency.

[0005] Therefore, a domestic waste high-temperature dry distillation carbonization incineration device is proposed to solve the above problems. Summary of the invention

[0018] Compared with the prior art, the present invention provides a high-temperature dry distillation carbonization incineration device for domestic waste, which has the following beneficial effects:

[0019] 1. Through the design of this scheme, the operator only needs to put the garbage into the decomposition and crushing bin through the transmission equipment for crushing. At the same time, the multifunctional decomposition feeding mechanism can automatically assist the crushing equipment to feed the carbonization incineration chamber combustion chamber. Not only can the crushing equipment and the auxiliary pushing equipment be operated synchronously to reduce the complexity of equipment operation, but also compared with the traditional garbage feeding method, it can reduce the risk of operators being scalded due to careless feeding. At the same time, this scheme adopts one machine for multiple purposes, which can not only crush the garbage but also carbonize and burn the garbage synchronously, increasing the applicability of the equipment while reducing the cumbersomeness of the operator's operation.

[0020] 2. The reciprocating sliding of the push block in the push chamber and the interaction of the buffer spring make the push block slide more linearly and smoothly in the push chamber, such as Figure 5As shown, the pushing block reciprocates to push the shaking plate to swing in the inner wall of the decomposition and crushing bin. When the crushed garbage falls onto the shaking plate, the shaking action of the shaking plate can quickly push the crushed garbage into the dry incineration chamber of the carbonization incineration chamber. Compared with the prior art of directly throwing the garbage, this solution can reduce the high temperature roasting and heat radiation during garbage incineration, which can easily cause occupational injuries such as burns and heat stroke.

[0021] 3. This solution can be set up to feed in the decomposition and crushing bin while cooperating with the rotation of the drying and combustion disk, so that garbage can be prevented from piling up during the feeding process. The rotation of the drying and combustion disk can evenly spread the garbage put in the decomposition and crushing bin in cooperation with the multifunctional decomposition and feeding mechanism in the drying and incineration chamber. At the same time, the rotation of the stirring rod can reduce the accumulation of garbage. The accumulation of garbage will cause incomplete combustion. When the garbage is not burned fully, a large amount of black smoke and harmful gases will be generated, such as dioxins and other highly toxic substances. These substances are extremely harmful to the environment and human health. In this solution, the garbage can be evenly spread to reduce the incomplete combustion of garbage, thereby reducing the generation of toxic and harmful substances. The oxygen distribution under the dynamic flow field can be controlled to avoid the re-synthesis of dioxins caused by local hypoxia, and the dioxin emission concentration can be stably lower than 0.1ng TEQ / Nm3

[0022] 4. This scheme can achieve the connection between the drying and incineration chamber and the carbonization chamber by setting a pulling guide tube. When the garbage in the drying and incineration chamber is evenly dried, the garbage is incinerated according to the combustion control. The garbage after preliminary incineration slides downward through the guide tube to drive the arc shovel plate to contact the garbage. Through the rotation of the drying combustion disk, the incinerated garbage can be pushed by the arc shovel plate to flow into the carbonization chamber through the middle of the drying combustion disk for carbonization. The scheme uses staged treatment. Because the temperature of the incineration chamber rises to above 100°C in the secondary combustion chamber, excessive oxygen is introduced to ensure that the combustible gas is fully burned and the residual organic matter and dioxins are completely decomposed. The temperature of the carbonization chamber is controlled at 400-600°C, and the organic matter is pyrolyzed into carbon slag and combustible gas in an oxygen-deficient environment to avoid the synthesis of dioxin precursors. At the same time, when the garbage is carbonized in this scheme, the residual heat generated by the carbonization can be transferred to the drying and incineration chamber through the heat conduction of the drying combustion disk to induce the garbage, thereby reducing energy consumption.

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.

[0036] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0037] First embodiment

[0038] Please refer to Figures 1 to 8 As shown:

[0039] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a high-temperature dry distillation carbonization incineration device for domestic waste, including a carbonization incineration chamber 1, a secondary combustion chamber 11 is installed above the carbonization incineration chamber 1, a primary purification device 12 is arranged on one side of the carbonization incineration chamber 1, a quenching chamber adsorption device 13 is arranged on the side of the primary purification device 12 away from the carbonization incineration chamber 1, a decomposition and crushing bin 14 is fixedly connected to the middle of the carbonization incineration chamber 1, and also includes a multifunctional decomposition feeding mechanism 2 and a multi-stage intelligent adjustment mechanism 3;

[0040] The multifunctional decomposition and feeding mechanism 2 is arranged on the decomposition and crushing bin 14, and the multifunctional decomposition and feeding mechanism 2 is used for automatic feeding during the initial crushing of the garbage;

[0041] The multi-stage intelligent regulating mechanism 3 is arranged in the carbonization incineration chamber 1, and the multi-stage intelligent regulating mechanism 3 is used for isolating and carbonizing the garbage after dry combustion;

[0042] The carbonization incineration chamber 1 is fixedly connected to the bottom of the secondary combustion chamber 11, the secondary combustion chamber 11 is fixedly connected to the primary purification device 12 through a pipeline, the primary purification device 12 is fixedly connected to the quench chamber adsorption device 13 through a pipeline, the inner wall of the secondary combustion chamber 11 is composed of multi-layer heat insulation materials, and a plasma arc device is installed in the middle of the secondary combustion chamber 11, and the power is adjustable;

[0043] Specifically, Figure 5 and Figure 6 As shown, the first transmission gear 21 is rotatably connected to both sides of the decomposition and crushing bin 14, a motor is installed on one side of the decomposition and crushing bin 14, and the motor drive shaft is fixedly connected to the middle of the first transmission gear 21 on one side of the decomposition and crushing bin 14, the tooth surface of the first transmission gear 21 is meshed with the second transmission gear 22, the middle part of the second transmission gear 22 is rotatably connected to the decomposition and crushing bin 14, and the first transmission gear 21 and the second transmission gear 22 are respectively fixed to the crushing shaft at the middle of a side away from the motor;

[0044] The crushing end face of the crushing shaft is made of special steel, and the surface is specially treated for corrosion resistance to extend its service life.

[0045] Further, an eccentric column 23 is fixedly connected to an eccentric part of one side of the first transmission gear 21 away from the decomposition and crushing bin 14, and a push plate 24 is rotatably connected to one end of the eccentric column 23 away from the second transmission gear 22, and a swing arm 25 is rotatably connected to one end of the push plate 24 away from the eccentric column 23, and a support plate 201 is rotatably connected to one end of the swing arm 25, and a crank 27 is rotatably connected to the other end of the swing arm 25; a push block 28 is rotatably connected to one end of the crank 27 away from the swing arm 25, and a push chamber 26 is fixedly connected to the one side of the decomposition and crushing bin 14 away from the carbonization and incineration chamber 1, and the outer surface of the push block 28 is slidably connected to the push chamber 26, and one end of the support plate 201 is fixed on the decomposition and crushing bin 14, and the other end of the support plate 201 is fixedly connected to the upper surface of the push chamber 26;

[0046] In this solution, the second transmission gear 22 rotates, and the eccentric column 23 rotates eccentrically around the middle of the second transmission gear 22 to drive the push plate 24 to reciprocate and push the swing arm 25 to swing back and forth on the support plate 201. The reciprocating swing of the swing arm 25 drives the crank 27 to drive the push block 28 to reciprocate in the push chamber 26.

[0047] Furthermore, a buffer spring 29 is symmetrically arranged in the pushing chamber 26, one end of the buffer spring 29 is fixedly connected to the pushing block 28, and the other end of the buffer spring 29 is fixedly connected to the pushing chamber 26. The decomposition and crushing chamber 14 is rotatably connected to a shaking plate 202 near the bottom of the crushing shaft. The shaking plate 202 is arranged at the connection between the pushing chamber 26 and the decomposition and crushing chamber 14, and is used for auxiliary feeding of the crushed garbage;

[0048] The push block 28 slides back and forth in the push chamber 26 and the interaction of the buffer spring 29 makes the push block 28 slide more linearly and smoothly in the push chamber 26. Figure 5 As shown, the pushing block 28 reciprocates to push the shaking plate 202 to swing in the inner wall of the decomposition and crushing bin 14. When the crushed garbage falls onto the shaking plate 202, the shaking action of the shaking plate 202 can quickly push the crushed garbage into the drying incineration chamber 1 of the carbonization incineration chamber 1. Compared with the prior art of directly putting the garbage into the drying chamber 1, this solution can reduce the high temperature roasting and heat radiation during garbage incineration, which can easily cause burns, heat stroke and other occupational injuries.

[0049] Compared with the existing garbage incineration equipment, a separate device is needed to crush the garbage before incineration, and then the operator puts the crushed garbage back into the combustion chamber for combustion, which not only wastes energy but also poses a risk of burns to the operator if the operator is not careful in feeding the garbage in the incineration chamber close to the incineration equipment. Under the design of this scheme, the operator only needs to put the garbage into the decomposition and crushing bin 14 through the transmission equipment for crushing, and the multifunctional decomposition feeding mechanism 2 can automatically assist the crushing equipment to feed the carbonization incineration chamber 1 combustion chamber, which can not only synchronize the crushing equipment with the auxiliary pushing equipment to reduce the complexity of equipment operation, but also reduce the risk of operators being scalded due to careless feeding compared with traditional garbage feeding methods. At the same time, this scheme adopts a one-machine-multi-purpose machine, which can not only crush the garbage but also carbonize and burn the garbage simultaneously, which increases the applicability of the equipment while reducing the tediousness of the operator's operation.

[0050] Specifically, Figure 4 and Figure 7As shown, the outer surface of the drying combustion disk 31 is rotatably connected to the inner wall of the carbonization incineration chamber 1, and a protective cover 32 is fixedly connected to the upper surface of the outer edge of the drying combustion disk 31. The drying combustion disk 31 is evenly provided with teeth 33 on one side close to the protective cover 32. The tooth surface of the teeth 33 is meshed with bevel teeth 34. A stirring rod 35 is fixedly connected to the middle of the bevel teeth 34. One end of the stirring rod 35 is rotatably connected to the inner wall of the carbonization incineration chamber 1, and the other end of the stirring rod 35 is rotated on the upper surface of the drying combustion disk 31. A linkage cylinder 37 is slidably connected to the middle of the drying combustion disk 31.

[0051] Among them, the stirring rod 35 is fixedly connected to the motor drive shaft, and the motor drives the stirring rod 35 to drive the drying combustion disk 31 to rotate on the inner wall of the carbonization incineration chamber 1 through the bevel teeth 34. At the same time, the drying combustion disk 31 can rotate and stir the garbage through the stirring rod 35 to quickly dry the garbage.

[0052] The present solution is provided with a mechanism that allows feeding into the decomposition and crushing bin 14 while cooperating with the rotation of the drying and combustion disc 31, so that garbage accumulation can be avoided during the feeding process. The garbage fed into the decomposition and crushing bin 14 in cooperation with the multifunctional decomposition and feeding mechanism 2 can be evenly laid in the drying and incineration chamber by the rotation of the drying and combustion disc 31. At the same time, the rotation of the stirring rod 35 can reduce the accumulation of garbage. Garbage accumulation can cause incomplete combustion. When the garbage is not burned completely, a large amount of black smoke and harmful gases, such as dioxins and other highly toxic substances, will be generated. These substances are extremely harmful to the environment and human health. In the present solution, the even laying of garbage can reduce the occurrence of incomplete combustion of garbage, thereby reducing the generation of toxic and harmful substances. The oxygen distribution under the dynamic flow field can be controlled to avoid the resynthesis of dioxins caused by local hypoxia.

[0053] Further, if Figure 7 and Figure 8 As shown, a guide cylinder 38 is arranged above the linkage cylinder 37, and the guide cylinder 38 is fixedly connected to the secondary combustion chamber 11. The upper surface of the linkage cylinder 37 is symmetrically fixedly connected with a curved shovel plate 36, and the curved shovel plate 36 is set to a curved shovel shape, which is used to push and separate the garbage for preliminary incineration. The end of the linkage cylinder 37 away from the guide cylinder 38 is fixedly connected to a connecting plate 39, and the end of the connecting plate 39 away from the linkage cylinder 37 is fixedly connected to a telescopic cylinder;

[0054] The carbonization and incineration chamber 1 is provided with a drying and incineration chamber and a carbonization chamber. The drying and incineration chamber is connected with the decomposition and crushing chamber 14. The drying and incineration chamber and the carbonization chamber can be connected and separated by sliding the guide tube 38.

[0055] Among them, this scheme can realize the connection between the drying and incineration chamber and the carbonization chamber by setting a pulling guide tube 38. When the garbage in the drying and incineration chamber is evenly dried, the garbage is incinerated according to the combustion control. The garbage after preliminary incineration slides downward through the guide tube 38, driving the arc shovel plate 36 to contact the garbage. Through the rotation of the drying and combustion disk 31, the incinerated garbage can flow into the carbonization chamber through the middle of the drying and combustion disk 31 under the push of the arc shovel plate 36 for carbonization. The scheme is processed in stages due to the incineration chamber When the temperature rises to above 1100°C, excess oxygen is introduced to ensure that the combustible gas is fully burned and the residual organic matter and dioxins are completely decomposed. The temperature of the carbonization chamber is controlled at 400-600°C, and the organic matter is pyrolyzed into carbon slag and combustible gases CO, H2, CH4, etc. in an oxygen-deficient environment to avoid the synthesis of dioxin precursors such as chlorobenzene. At the same time, when the garbage is carbonized in this scheme, the residual heat generated by the carbonization can be transferred to the dry incineration chamber through the dry combustion disk 31 to induce the garbage, thereby reducing energy consumption.

[0056] The specific implementation process of the above embodiment is as follows:

[0057] First, the operator transfers the sorted garbage to the crushing port above the decomposition and crushing bin 14 through the transmission mechanism. At this time, the operator starts the driving motor installed on the decomposition and crushing bin 14 to rotate. The rotation of the motor can drive the crushing shaft in the decomposition and crushing bin 14 to crush the garbage. At the same time, the first transmission gear 21 and the second transmission gear 22 are mutually meshed and transmitted. In this scheme, the second transmission gear 22 rotates, and the eccentric column 23 rotates eccentrically around the middle of the second transmission gear 22 to drive the push plate 24 to reciprocate and push the swing arm 25 to swing back and forth on the support plate 201. The reciprocating swing of the swing arm 25 drives the crank 27 to drive the push block 28 to reciprocate in the push chamber 26. The reciprocating sliding of the push block 28 in the push chamber 26 and the interaction of the buffer spring 29 make the push block 28 more linear and stable when sliding in the push chamber 26, such as Figure 5 As shown, the pushing block 28 reciprocates to push the shaking plate 202 to swing in the inner wall of the decomposition and crushing bin 14. When the crushed garbage falls onto the shaking plate 202, the swinging action of the shaking plate 202 can quickly push the crushed garbage into the drying incineration chamber of the carbonization incineration chamber 1; the multifunctional decomposition feeding mechanism 2 can automatically assist the crushing equipment to feed the carbonization incineration chamber 1 combustion chamber, which can not only synchronize the crushing equipment with the auxiliary pushing equipment and reduce the complexity of equipment operation, but also reduce the risk of operators being scalded due to careless loading compared to traditional garbage loading methods. At the same time, this solution adopts a one-machine-multi-purpose machine, which can not only crush the garbage but also carbonize and burn the garbage simultaneously, increasing the applicability of the equipment while reducing the complexity of the operator's operation.

[0058] Furthermore, due to the synchronous start-up of the equipment, the driving motor connected to the stirring rod 35 rotates synchronously at this time, and the rotation of the stirring rod 35 can synchronously drive the bevel teeth 34 to drive the drying and combustion disk 31 to rotate. At this time, the garbage pushed by the multifunctional decomposition feeding mechanism 2 is continuously and evenly laid in the drying and incineration chamber of the drying and combustion disk 31 under the rotation of the drying and combustion disk 31. At the same time, the rotation and stirring action of the stirring rod 35 can reduce the uneven dry combustion caused by local accumulation of garbage, thereby reducing the generation of toxic and harmful substances. The oxygen distribution under the dynamic flow field is controllable to avoid the re-synthesis of dioxins caused by local hypoxia, and the dioxin emission concentration can be stably lower than 0.1ng TEQ / Nm 3 ;

[0059] Furthermore, by setting a pulling guide tube 38, the connection between the drying and incineration chamber and the carbonization chamber can be achieved. When the garbage in the drying and incineration chamber is evenly dried, the garbage is incinerated according to the combustion control. The garbage after preliminary incineration slides downward through the guide tube 38, driving the arc shovel plate 36 to contact the garbage. Through the rotation of the drying and combustion disk 31, the incinerated garbage can flow into the carbonization chamber through the middle of the drying and combustion disk 31 under the push of the arc shovel plate 36 for carbonization. The scheme is processed in stages due to the incineration room temperature. The temperature rises to above 1100°C, and excessive oxygen is introduced to ensure that the combustible gas is fully burned and the residual organic matter and dioxins are completely decomposed. The temperature of the carbonization chamber is controlled at 400-600°C, and the organic matter is pyrolyzed into carbon slag and combustible gases CO, H2, CH4, etc. in an oxygen-deficient environment to avoid the synthesis of dioxin precursors such as chlorobenzene. At the same time, when the garbage is carbonized in this scheme, the residual heat generated by the carbonization can be transferred to the dry incineration chamber through the dry combustion disk 31 to induce the garbage, thereby reducing energy consumption;

[0060] The gas generated by incineration and carbonization passes through the secondary combustion chamber 11 for secondary combustion. A plasma arc device is installed in the middle of the secondary combustion chamber 11, and the power is adjustable to further reduce the generation of harmful substances and tar. The gas after secondary full combustion in the secondary combustion chamber 11 passes through the primary purification device 12 for preliminary purification. During the purification, dioxins and heavy metals can be removed and particulate matter can be captured through bag dust removal and activated carbon adsorption. The emission concentration is ≤10mg / m 3 At this time, the gas that has undergone multi-stage purification is quickly cooled to below 200° C. through the quenching tower of the quenching chamber adsorption device 13 to prevent dioxin from being resynthesized.
