[0002] Garbage disposal is a complex and important process that aims to reduce the pollution of garbage to the environment and achieve sustainable use of resources. The commonly used method is incineration, which mainly places the garbage in a high-temperature furnace to fully oxidize the combustible components and use the heat generated for power generation and heating. With the acceleration of urbanization and the improvement of environmental awareness, the future treatment of urban domestic waste will pay more attention to resource utilization, harmlessness and reduction.

[0003] A Chinese patent with publication number CN108980847A discloses a garbage carbonization combustion treatment process, the steps of which include: sending the garbage to the drying grate of the drying chamber; dehydrating and drying the garbage on the drying grate through the rising hot air flow and furnace heat radiation generated when the garbage is burned in the combustion chamber; opening the drying grate to allow the dehydrated and dried garbage to fall onto the carbonization grate of the carbonization chamber, and using the flame temperature and high-temperature flue gas when the garbage is burned in the combustion chamber to perform high-temperature oxygen-deficient carbonization pyrolysis; opening the carbonization grate to allow the carbonized garbage to fall onto the combustion grate of the combustion chamber and burn; the flue gas generated when the garbage is burned in the combustion chamber enters the burnout chamber for secondary combustion; the flue gas after secondary combustion is cooled in the quenching chamber and then sent to the flue gas treatment system; and is discharged after being treated in turn by a dust removal device, an acid removal device and a sulfur removal device; the present invention can solve the technical problems of low garbage treatment efficiency, low degree of automation, and substandard tail gas emissions in existing small-scale garbage treatment equipment.

However, when it is burning, the flue gas is discharged directly according to environmental protection requirements. However, there will inevitably be some unused oxygen in these flue gases, and the subsequent wind ratio cannot be adjusted, otherwise the garbage may not be fully burned. At this time, there will be a certain amount of waste in the oxygen in the flue gas. The continuous reciprocating greatly increases the energy required for garbage combustion, and the efficiency of garbage combustion needs to be improved; therefore, an energy-saving garbage combustion process is proposed to address the above problems.

[0037] 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.

[0038] Embodiment 1

[0039] See also Figure 1 - Fig.11 As shown, an energy-saving garbage combustion process comprises the following steps:

[0040] The first step: sending the garbage into the interior of the incinerator 1, wherein the interior of the incinerator 1 is provided with a drying chamber 2, a No. 1 combustion chamber 3, a No. 2 combustion chamber 4 and a burnout chamber 5 in sequence; the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5 are evenly arranged on the inner circumference of the incinerator 1;

[0041] Step 2: When placing garbage, mainly place the garbage inside the incineration bucket 6, wherein four incineration buckets 6 are provided, and the four incineration buckets 6 are rotatably connected at the bottom of the inner wall of the incinerator 1. When working, the four incineration buckets 6 are respectively arranged inside the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5, and rotate and change positions according to the process steps;

[0042] Step 3: Dry the garbage in the drying chamber 2; burn the garbage in the No. 1 combustion chamber 3 and the No. 2 combustion chamber 4, and completely burn the garbage in the burnout chamber 5;

[0043] Step 4: The smoke generated by the combustion in the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5 is collected by the smoke recirculation fan 7, and then the smoke is respectively introduced into the No. 1 combustion chamber 3 and the burnout chamber 5;

[0044] During operation, in the process of garbage incineration, the garbage first enters the incinerator 1. In this process, the incineration bucket 6 is used to load the garbage, and four incineration buckets 6 are set, which can be rotated inside the incinerator 1, so as to adjust the different incineration buckets 6 to continuously change positions between the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5. The drying stage is carried out first during incineration. In this stage, it is mainly carried out in the drying chamber 2. The moisture in the garbage evaporates rapidly at high temperature, making the garbage drier and convenient for subsequent combustion. The drying temperature is controlled between 60°C and 90°C. As the temperature of the garbage continues to rise, the chemical reaction rate gradually accelerates, and the exothermic reaction front propagates at a certain rate on the material layer. The garbage begins to enter the combustion stage. When it is necessary to enter the combustion stage, the incineration bucket 6 passing through the drying chamber 2 rotates and enters the No. 1 combustion chamber 3 for combustion. The combustibles in the garbage are burned through the No. 1 combustion chamber 3. The combustible materials in the garbage are fully burned. In this stage, the combustible materials in the garbage burn rapidly under high temperature and sufficient oxygen conditions, releasing a large amount of heat energy. At the same time, the organic matter in the garbage will undergo pyrolysis at high temperature to produce combustible gases and volatiles. These substances help to improve the overall combustion efficiency. In order to ensure more complete combustion, it enters the No. 2 combustion chamber 4 after passing through the No. 1 combustion chamber 3. On the basis of the No. 1 combustion chamber 3, the combustible materials in the garbage continue to be burned, and the organic matter that is not completely pyrolyzed is promoted to further decompose. Through continuous combustion reaction, the high temperature environment in the furnace is maintained to provide conditions for the complete combustion and subsequent treatment of the garbage. In the combustion stage, whether it is in the No. 1 combustion chamber 3 or the No. 2 combustion chamber 4, the temperature is usually high, which can reach 850℃-1000℃, to ensure that the garbage can be fully burned. Finally, it enters the burnout chamber 5 to completely burn the incompletely burned garbage. At this stage, most of the combustible materials in the garbage have been burned, leaving only some difficult-to-burn materials. Here, a certain amount of time needs to be guaranteed, controlled within one hour, to ensure that the combustible materials in the garbage are fully burned and reduce the heat loss of the slag. The overall key point is still to set up a flue gas recirculation fan 7, which can recycle the combustion flue gas generated by the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5, and pass it into the No. 1 combustion chamber 3 and the burnout chamber 5 for reuse. This function can ensure that the burnout chamber 5 can further burn the garbage without adding a large amount of air, thereby reducing the thermal loss rate of the slag and improving the efficiency of garbage combustion.

[0045] Furthermore, in the second step, the air volume and air pressure inside the drying chamber 2 and the second combustion chamber 4 are adjusted as needed through a manual control program. In the third step, a stirring assembly is provided inside the drying chamber 2, and the combustible materials of the garbage inside the first combustion chamber 3 are rapidly burned under high temperature and sufficient oxygen conditions, releasing a large amount of heat energy. The garbage inside the second combustion chamber 4 continues to burn the combustible materials in the garbage on the basis of the first combustion chamber 3, and promotes the further decomposition of the organic matter that is not completely pyrolyzed.

[0046] During operation, a manual control program is set up, which can be manually adjusted during the burning of garbage, and is used to adjust the air volume and air pressure inside the drying chamber 2 and the No. 2 combustion chamber 4, so that the garbage can be fully dried inside the drying chamber 2 and fully burned in the No. 2 combustion chamber 4. The stirring component is set inside the drying chamber 2, which is used to stir the garbage during drying. At the same time, the combustible material of the garbage inside the No. 1 combustion chamber 3 burns rapidly under high temperature and sufficient oxygen conditions, releasing a large amount of heat energy. The No. 1 combustion chamber 3 is adjacent to the drying chamber 2. The heat can be fully used for drying the garbage, and there is no need to increase more heat during drying, thereby saving heat energy. The garbage inside the No. 2 combustion chamber 4 continues to burn the combustible material in the garbage on the basis of the No. 1 combustion chamber 3, and promotes further decomposition of organic matter that is not completely pyrolyzed, thereby improving the combustion efficiency.

[0047] Furthermore, a transmission column 8 is fixedly connected to the surface of the incineration bucket 6, and the bottom end of the transmission column 8 is rotatably connected to the bottom of the inner wall of the incinerator 1. Four incineration buckets 6 are evenly arranged on the surface circumference of the transmission column 8. A support isolation plate 9 is fixedly connected to the inner wall of the incinerator 1. The top of the transmission column 8 passes through the support isolation plate 9 and extends to the top of the support isolation plate 9. One end of the transmission column 8 located at the top of the support isolation plate 9 is fixedly connected to a transmission shaft 10. An external motor barrel 11 is fixedly connected to the top of the incinerator 1. An upper motor 12 is fixedly connected to the interior of the external motor barrel 11, and the output shaft of the upper motor 12 is fixedly connected to the top of the transmission shaft 10 through a coupling.

[0048] During operation, the transmission column 8 is fixed on the surface of the incineration bucket 6 and can rotate on the surface of the supporting isolation plate 9 and the bottom of the inner wall of the incinerator 1. The four incineration buckets 6 are all fixed on the transmission column 8, and the incineration buckets 6 are driven to rotate by the transmission column 8. At the same time, the supporting isolation plate 9 is arranged on the top of the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5, and separates the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5 from the top of the incinerator 1, so that there is a buffer area between the top of the inner wall of the incinerator 1 and the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5, and an external motor cylinder 11 is fixed on the top of the incinerator 1, and an upper motor 12 is installed and supported inside the external motor cylinder 11. The output shaft of the upper motor 12 is fixedly connected to the bottom end of the transmission shaft 10 through a coupling, so that when the upper motor 12 is working, it can drive the transmission shaft 10 to start rotating through the output shaft. The bottom end of the transmission shaft 10 is fixedly connected to the top of the transmission column 8, so that after the transmission shaft 10 rotates, it can drive the transmission column 8 to start rotating, thereby providing energy for adjusting the rotation of the incineration bucket 6. The overall function of the four incineration buckets 6 rotating in the drying chamber 2, the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5 is realized. The position of the incineration bucket 6 can be adjusted according to the process, and one process can be completed before transferring to the next process. Combined with the existing garbage burning, the garbage is always put into the incinerator 1 for incineration, and then garbage is continuously added. After the internal garbage is burned out, it will slowly accumulate. Some of the accumulated garbage may not be completely burned. The method of rotating and adjusting the incineration bucket 6 solves the problem of inconvenient transportation of the combustion position, which leads to the accumulation of garbage and inability to burn completely due to the addition of garbage. Different garbage burning processes can be cyclically carried out, which improves the adaptability of garbage burning.

[0049] Further, the stirring assembly includes a built-in motor cylinder 13, the built-in motor cylinder 13 is fixed on the top of the supporting isolation plate 9, the built-in motor cylinder 13 is fixedly connected to the inside of the built-in motor cylinder 13, the output shaft of the built-in motor 14 is fixedly connected to an electric telescopic rod 15 through a coupling, one end of the electric telescopic rod 15 passes through the supporting isolation plate 9 and extends to the inside of the drying chamber 2, and the end of the electric telescopic rod 15 located inside the drying chamber 2 is fixedly connected to a spiral stirring blade 16;

[0050] When working, the built-in motor cylinder 13 is a part of the stirring assembly, which is fixed on the top of the supporting isolation plate 9 and is used to install and support the built-in motor 14. When the built-in motor 14 is working, the electric telescopic rod 15 starts to rotate through the output shaft. The electric telescopic rod 15 can be extended and retracted inside the drying chamber 2. When drying is required, the electric telescopic rod 15 drives the spiral stirring blades to move downward and move to the inside of the incineration bucket 6 at the bottom of the drying chamber 2. The rotation of the electric telescopic rod 15 drives the spiral stirring blades to rotate, stir the garbage, and then stir the garbage in the incineration bucket 6 in the drying chamber 2, increase the heating area of ​​the garbage, speed up the drying, solve the problem that it takes more time to dry when there is a lot of garbage, and improve the drying efficiency. After drying is completed, the electric telescopic rod 15 moves the spiral stirring blades 16 upward and separates them from the incineration bucket 6, which also avoids the problem that the spiral stirring blades 16 affect the rotation of the incineration bucket 6.

[0051] Furthermore, a smoke collecting box 17 is fixedly connected to the top of the inner wall of the No. 2 combustion chamber 4, and the smoke recirculation fan 7 is fixed to the bottom of the inner wall of the smoke collecting box 17. The top and bottom of the smoke collecting box are respectively connected with an L-shaped smoke recovery pipe 18 and a smoke recovery riser 19, and the number of the L-shaped smoke recovery pipes 18 is set to two, and the two smoke recovery pipes respectively penetrate the supporting isolation plate 9 and extend to the interior of the No. 1 combustion chamber 3 and the burnout chamber 5, and the smoke recovery riser 19 extends to the interior of the No. 2 combustion chamber 4. The bottom ends of the L-shaped smoke recovery pipe 18 and the smoke recovery riser 19 are both connected with an air suction hopper 20, and both sides of the surface of the smoke recirculation fan 7 are connected with air guide hoses 21, and the number of the air guide hoses 21 is set to two, and one end of the two air guide hoses 21 respectively penetrates the smoke collecting box 17 and extends to the interior of the No. 1 combustion chamber 3 and the burnout chamber 5;

[0052] During operation, the smoke collecting box 17 is arranged inside the second combustion chamber 4 and at the bottom of the supporting isolation plate 9. The interior is used to install and support the smoke recirculation fan 7. The top of the smoke collecting box 17 is connected to two L-shaped smoke recovery pipes 18. One end of the two L-shaped smoke recovery pipes 18 respectively penetrates to the top of the first combustion chamber 3 and the burnout chamber 5. The bottom of the smoke collecting box 17 is connected to the smoke recovery riser 19. The bottom ends of the L-shaped smoke recovery pipe 18 and the smoke recovery riser 19 are both connected to the suction hopper 20. The flue gas generated in the No. 1 combustion chamber 3, the No. 2 combustion chamber 4 and the burnout chamber 5 in the incinerator 1 is sucked in and passed into the interior of the flue gas collecting box 17. The flue gas entering the flue gas collecting box 17 is processed by the flue gas recirculation fan 7 and then introduced into the interior of the No. 1 combustion chamber 3 and the burnout chamber 5 by the air guide hose 21, thereby making full use of the combustion-supporting gas in the flue gas and eliminating the need for a large amount of supplementary air, thereby achieving the effect of adjusting the secondary air ratio, reducing the amount of secondary air entering the furnace, reducing the work of the secondary fan, and achieving the effect of energy saving.
