Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste incineration, in particular to a waste incinerator capable of improving incineration efficiency. BACKGROUND

[0002] The waste incinerator involved in the present application is an environmental protection equipment commonly used for solid harmless treatment of household garbage, medical waste and the like, which converts waste into ash, waste gas and heat through high-temperature incineration, so as to achieve the purposes of reducing the volume of garbage, disinfection and sterilization and heat energy utilization.

[0003] In the Chinese patent with patent publication number CN211650252U, a waste incinerator with high waste incineration efficiency is disclosed, which comprises a furnace body, a support is welded below the incinerator body, a fan is arranged above the support, one end of the fan is connected with a tuyere cover through a wind pipe penetrating through the incinerator body, an ash plate is arranged at the outer edge of the tuyere cover, an ash door is installed on both sides of the incinerator body through mounting screws, a fastening bolt is sleeved on the outer wall of the mounting screw, a heat insulation interlayer is arranged on the inner wall of the incinerator body, and a bottom plate is clamped above the ash plate in the incinerator body. The device is provided with a heat collecting plate in the incinerator body, and a heat collecting pipe is arranged above the heat collecting plate, so that the device can recycle the heat energy generated by incineration, improve the energy saving property of the device, and improve the heat collecting efficiency.

[0004] However, the device in the above-mentioned reference file still has the following defects in specific use:

[0005] 1. Compared with the device in the above-mentioned reference file, in the actual use process, it is a simple straight falling type feeding. Although the straight falling type feeding method is relatively simple, the garbage can directly fall into the combustion chamber of the incinerator, however, this method will cause uneven distribution of garbage on the grate. Due to the different characteristics of the shape, density and water content of the garbage, direct falling will cause the garbage to accumulate too thick in some areas, while the garbage in some areas is relatively sparse. This uneven distribution will affect the combustion process of the garbage. The garbage area with too thick accumulation cannot be fully combusted due to insufficient oxygen supply, while the sparse area cannot maintain stable combustion state due to too fast heat loss. This uneven combustion state will reduce the overall combustion efficiency, and some garbage cannot be completely combusted, thereby increasing the amount of slag and fly ash produced.

[0006] 2. Meanwhile, compared to the device in the above-mentioned referenced documents that uses a single type of furnace body, the path of the waste from the feed inlet to the combustion chamber in a single incinerator is relatively short, resulting in insufficient preheating residence time of the waste in the furnace. Due to the short residence time, the waste is directly put into the combustion chamber for incineration without being fully preheated. Insufficient preheating will reduce the thermal efficiency of the incinerator, requiring more fuel to maintain the furnace temperature, increasing operating costs. At the same time, incompletely burned waste will produce more harmful gases and particulate matter, increasing the difficulty and cost of flue gas purification, and causing greater pollution to the environment.

[0007] Furthermore, compared to common waste incinerators in existing technologies, their air distribution systems are mostly static fixed air outlets, resulting in a relatively simple gas distribution. In actual operation, the static fixed air outlet air distribution system cannot be flexibly adjusted according to the combustion status of the waste in the furnace and the flame distribution. Specifically, uneven gas distribution will lead to insufficient oxygen supply in some areas, resulting in incomplete combustion of waste, producing black smoke and unburned slag, which reduces combustion efficiency and thermal efficiency. At the same time, local overheating areas will aggravate corrosion and wear inside the furnace, shortening the service life of the incinerator. In addition, incompletely burned waste will also produce more harmful gases and particulate matter, increasing the difficulty of flue gas purification and environmental pressure.

[0008] Therefore, in view of this, the present invention proposes a waste incinerator that can improve incineration efficiency to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides a waste incinerator that can improve incineration efficiency, thereby resolving the technical issues raised in the background section.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a waste incinerator that can improve incineration efficiency, comprising an incinerator body, a support base installed at the bottom of the incinerator body, and a composite processing mechanism arranged inside the incinerator body, wherein the composite processing mechanism adopts multi-stage rotary feeding and composite processing of waste raw materials.

[0011] Furthermore, the composite processing mechanism includes a drive motor installed below the incinerator body. The output shaft of the drive motor is fixedly connected to a connecting shaft. The outer wall of the connecting shaft is uniformly equipped with drive gears. Driven gear rings mesh with the outer sides of the drive gears. Storage bins are installed above the driven gear rings. Layered filter racks are installed on the inner walls of the storage bins. A spiral pipe is provided inside the incinerator body. A furnace bottom component is installed at the bottom of the incinerator body. A cylindrical assembly is installed on the surface of the furnace bottom component.

[0012] Further, the connecting shaft penetrates the surface of the support base, and the connecting shaft is in rotational connection with the surface of the support base.

[0013] By adopting the above technical scheme, the up-and-down penetrating connection mode ensures the stability of the connecting shaft during rotation.

[0014] Further, the storage bin is in the shape of a ring, and an adaptive groove is arranged at the joint position of the storage bin and the connecting shaft, the storage bin and the connecting shaft are in sliding connection through the adaptive groove, and the inside of the storage bin is filled with a heat-sensitive material.

[0015] Further, the layered filter frame is in fixed connection with the uppermost driven gear ring, the layered filter frame is in the shape of a funnel with a wide upper part and a narrow lower part, the upper half of the layered filter frame is a covering surface, and the lower half is a filter screen surface, and the outer wall of the upper half of the layered filter frame is uniformly fixedly connected with a spoiler.

[0016] By adopting the above technical scheme, the rotating spoiler can break the upward flowing hot gas, so that the flow path of the hot gas becomes complex and turbulent, and the contact area and contact time of the hot gas with the garbage and the filter frame itself are increased.

[0017] Further, the spiral pipe is in communication with the feeding port above the incinerator body and the output port below the layered filter frame, and the inner diameter of the spiral pipe and the output port below the layered filter frame is the same as the inner diameter of the feeding port above the incinerator body.

[0018] Further, the spiral pipe is in the form of double layers, and flow guide spikes are uniformly arranged in the interlayer of the spiral pipe, and the flow guide spikes are fixedly connected to the inner side wall of the interlayer in the form of inclined upward.

[0019] By adopting the above technical scheme, the flow guide spikes are fixedly connected to the inner side wall of the interlayer in the form of inclined upward, which can effectively guide the flow direction of the hot gas and avoid the formation of vortex or stagnant area in the interlayer.

[0020] Further, the furnace bottom part is in the shape of a semicircle, an elliptical protrusion is fixedly connected to the middle part of the furnace bottom part, a plurality of cylinder groups are combined to form a cylinder group, the plurality of cylinder groups are located between the side wall of the furnace bottom part and the elliptical protrusion, and the distribution and height of the plurality of cylinder groups are irregular.

[0021] By adopting the above technical scheme, the irregular distribution and height of the plurality of cylinder groups ensure that the garbage does not tightly accumulate on the furnace bottom part, and a certain interval space is maintained between adjacent garbage.

[0022] Further, the outside of the incinerator body is provided with a ventilation module, the inside of the ventilation module is provided with a dynamic ventilation mechanism, the dynamic ventilation mechanism comprises a ventilation pipeline communicated with the inside of the incinerator body, the ventilation pipeline is externally provided with a limiting ring at one end close to the incinerator body, the inside of the limiting ring is uniformly provided with a plurality of ball groups, a connecting spring is arranged between every two adjacent ball groups, the inner side wall of the ventilation pipeline is fixedly connected with a wind distribution disc, and the side wall of the wind distribution disc is fixedly connected with a shunt column.

[0023] Further, the two ends of the connecting spring are fixedly connected with the incinerator body and the limiting ring respectively, the wind distribution disc is composed of a plurality of inclined fan-shaped assemblies, and the outer wall of the shunt column is in the form of a sharp end.

[0024] By adopting the above technical scheme, the outer wall of the shunt column is in the form of a sharp end, so that the airflow can be efficiently divided like a wedge, and the airflow will not be concentrated in a certain area after passing through the wind distribution disc.

[0025] Further, the ventilation module comprises an air inlet pipeline and an air outlet pipeline, and the ventilation pipeline is in communication with the air inlet pipeline in the ventilation module.

[0026] Compared with the prior art, the beneficial effects of the present application are:

[0027] (1) The device adopts multi-stage rotary feeding, in the feeding process, the garbage first enters the first rotary chamber, and is preliminarily preheated by the ascending hot air in the incinerator body, effectively improving the initial temperature of the garbage and enhancing its reaction activity, then the garbage gradually falls to the middle rotary chamber, and realizes full mixing and screening in the rotary process, so that the physical properties of the garbage are more uniform, and finally falls to the combustion chamber, through this multi-stage pretreatment, the combustion efficiency of the garbage entering the combustion chamber is greatly improved, the generation of incomplete combustion products is reduced, and the continuity and stability of the incineration process are ensured.

[0028] Compared with the traditional straight falling type feeding, the device realizes the pretreatment operation of multi-stage rotary feeding and screening, so that the garbage is uniformly dispersed into the combustion chamber, the distribution of the garbage on the grate is optimized, and the spiral form of the feeding prolongs the falling time of the garbage, thereby providing the basis for the preheating of hot gas, which not only ensures that the garbage in each area can obtain sufficient oxygen supply and realize full combustion, but also stabilizes the combustion state, reduces the generation amount of slag and fly ash, and greatly improves the energy utilization efficiency.

[0029] Compared with the traditional straight-through single incinerator, the device divides the incinerator into multiple areas through the introduced structure without affecting the normal use of the combustion chamber inside the incinerator, so that the garbage needs to pass through these areas in turn before entering the combustion chamber, thereby prolonging the residence time of the garbage in the furnace, and through the longer residence time, the garbage can be fully preheated, the water content is reduced, and the pyrolysis of organic matter is promoted, thereby reducing fuel consumption and operating costs.

[0030] More importantly, the spiral pipeline adopts a double-layer structure, and inclined upward flow guide spikes are uniformly installed on the inner side wall of the interlayer. On the one hand, the design of the interlayer fully utilizes the physical characteristics of the upward flow of hot air, introduces part of the hot gas into the interlayer, and forms a circulating flow of heat. This design not only reduces heat loss, but also realizes the reuse of heat energy, thereby reducing the energy consumption of the system. On the other hand, when the hot gas flows through the interlayer, it is guided by the flow guide spikes and flows along the inner side wall of the spiral pipeline, continuing to preheat the raw materials inside the pipeline. This preheating process, combined with the above-mentioned spiral feeding process, can effectively reduce the initial water content of the raw materials and promote the early pyrolysis of organic matter, thereby optimizing the combustion characteristics of the raw materials.

[0031] Among them, the flow guide spikes are fixedly connected to the inner side wall of the interlayer in the form of inclined upward, which can effectively guide the flow direction of the hot gas and avoid the formation of vortex or stagnant area in the interlayer. Moreover, due to the curved shape of the spiral pipeline, the flow path of the hot gas is increased, thereby enhancing the heat exchange efficiency between the hot gas flow and the pipeline wall and further improving the preheating effect.

[0032] More importantly, the driving motor drives the driving gear and the driven gear ring, and then rotates the layered filter frame inside the middle rotating chamber of the incinerator body, providing a basis for the cooperation of the layered filter frame and the spiral pipeline. The rotation of the layered filter frame and the communication design of the spiral pipeline ensure that the garbage raw materials can be evenly distributed when entering the incinerator, avoiding the accumulation of raw materials at the same position. This uniform distribution helps to optimize the combustion process and prevent insufficient oxygen supply or insufficient combustion in local areas due to excessive thickness of raw materials. Moreover, the rotation of the layered filter frame and the coordinated feeding of the spiral pipeline ensure continuous feeding of the garbage raw materials, avoiding the problem of blockage caused by accumulation or jamming of raw materials. In addition, the uniform distribution of garbage can also make the heat distribution in the incinerator more balanced, avoiding local overheating, thereby reducing the thermal stress inside the furnace body, reducing the risk of deformation and damage of the equipment due to local overheating, prolonging the service life of the equipment.

[0033] The upper half layer of the layered filter frame is a cover surface, the lower half layer is a filter screen surface, and the outer wall of the upper half layer has a spoiler. First, the spoiler in the upper half layer can break the upward flowing hot gas, making the flow path of the hot gas complex and turbulent, increasing the contact area and contact time of the hot gas with the garbage and the filter frame itself, which helps to improve the heat exchange efficiency, so that the heat in the hot gas is more fully transferred to the garbage, preheating the garbage and further improving the combustion effect. Second, the filter screen surface of the lower half layer can preliminarily screen and filter the transported garbage, intercepting some larger garbage blocks or impurities in the upper layer, and allowing smaller and more easily combustible garbage particles to pass through into the lower layer for combustion. This can make the size of the garbage particles entering the combustion chamber more uniform, which is beneficial to subsequent stable combustion and full reaction.

[0034] Especially important is that the device introduces a semicircular arc-shaped furnace bottom piece at the bottom of the incinerator body, and introduces a plurality of irregularly distributed cylinders in the middle position. First, the irregular distribution and height design of the plurality of cylinder groups ensure that the garbage will not be tightly stacked on the furnace bottom piece, and a certain interval space is maintained between adjacent garbage. This design makes the garbage more evenly distributed during the incineration process, avoiding local accumulation or sparse phenomenon, thereby optimizing the combustion process. Second, the interval space between adjacent garbage also provides a channel for the hot gas flow, allowing the hot gas flow to flow more smoothly, enhancing the heat exchange efficiency between the hot gas flow and the garbage. Smooth hot gas flow can ensure that the garbage is in full contact with the hot gas flow, thereby improving the combustion efficiency and reducing the generation of unburned substances.

[0035] (2) The device realizes the irregular rotation of the introduced ventilation pipeline under the action of wind pressure by the combined use of the limiting ring, the ball shaft and the spring, which promotes the combustion-supporting air to flow into the furnace in different directions and speeds, creating a turbulent flow field. This turbulent flow strengthens the mixing degree of the combustion-supporting air and the garbage, increases the contact area and frequency of the gas-solid two-phase, and thus helps the garbage to burn more quickly and fully, thereby improving the overall combustion efficiency.

[0036] Among them, the strong turbulent effect makes the flow of combustion-supporting air in the furnace more complex and disordered, which breaks the boundary layer limitation under the traditional laminar flow state, making the heat exchange between the high-temperature flue gas and the garbage and the furnace wall more sufficient, improving the heat transfer efficiency and helping to improve the thermal efficiency, so that the heat energy generated by garbage incineration can be more efficiently utilized.

[0037] Compared with the traditional static fixed tuyere air distribution system, the gas distribution is single, which causes uneven distribution of oxygen in the furnace, the ventilation pipeline in the device uniformly distributes the combustion air by forming a turbulent flow, eliminates the oxygen distribution dead angle, ensures sufficient combustion of the garbage, greatly improves the combustion efficiency, and secondly, optimizes the combustion air distribution, makes the temperature field in the furnace tend to be uniform, effectively reduces the local overheating phenomenon, reduces the thermal shock and chemical corrosion of the equipment, prolongs the service life of the key parts inside the incinerator, reduces the equipment maintenance cost and shutdown maintenance frequency.

[0038] The outer wall of the flow dividing column is in the form of a sharp end, which can effectively divide the airflow like a wedge, so that the airflow is not concentrated in a certain area after passing through the air distribution disc, but is dispersed in multiple directions, making the airflow distribution more uniform, avoiding the situation of local airflow being too strong or too weak, and providing a clear guiding path for the divided airflow, so that the airflow flows to the interval of the air distribution disc according to the designed direction.

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application;

[0055] It should be noted that the structure and working principle of the above-mentioned incinerator body 1, supporting base 11, ventilation module 12 and other devices belong to the prior art, and will not be described here. EMBODIMENT

[0056] Please refer to Figure 1 and Figure 2 A garbage incinerator capable of improving incineration efficiency is shown, which comprises an incinerator body 1, a supporting base 11 installed at the bottom of the incinerator body 1, a composite processing mechanism 2 arranged inside the incinerator body 1, a multi-section rotary feeding, and a composite processing of garbage raw materials.

[0057] It should be noted that the ventilation module 12 comprises an air inlet pipe and an air outlet pipe, and the ventilation pipe 31 is in communication with the air inlet pipe in the ventilation module 12.

[0058] Please refer to Figures 2 to 8 The composite processing mechanism 2 comprises a driving motor 21 installed below the incinerator body 1, a connecting shaft 22 fixedly connected to the output shaft end of the driving motor 21, driving gears 23 uniformly installed on the outer wall of the connecting shaft 22, driven gear rings 24 engaged with the outside of the driving gears 23, storage bins 25 installed above the driven gear rings 24, layered filter frames 26 installed on the inner wall of the storage bins 25, a spiral pipe 28 arranged inside the incinerator body 1, a furnace bottom 210 installed at the bottom of the incinerator body 1, and a cylindrical group 211 installed on the surface of the furnace bottom 210.

[0059] It should be noted that the connecting shaft 22 penetrates the surface of the support base 11 up and down, the connecting shaft 22 is rotatably connected with the surface of the support base 11, the driven gear ring 24 is rotatably connected with the incinerator body 1, the storage bin 25 is in the shape of a ring, an adaptive slot is formed at the joint position of the storage bin 25 and the connecting shaft 22, the storage bin 25 and the connecting shaft 22 are slidably connected through the adaptive slot, the inside of the storage bin 25 is filled with a heat-sensitive material, the layered filter frame 26 is fixedly connected with the uppermost driven gear ring 24, the layered filter frame 26 is in the shape of a funnel with a wide top and a narrow bottom, the upper half of the layered filter frame 26 is a cover surface and the lower half is a filter surface, the outer wall of the upper half of the layered filter frame 26 is uniformly fixedly connected with a spoiler 27, the spiral pipe 28 is in communication with the feed inlet above the incinerator body 1 and the output port below the layered filter frame 26, respectively, and the inner diameter of the spiral pipe 28 and the output port below the layered filter frame 26 is the same as the inner diameter of the feed inlet above the incinerator body 1, the spiral pipe 28 is in a double-layer form, the interlayer of the spiral pipe 28 is uniformly provided with a flow guide spike 29, the flow guide spike 29 is fixedly connected to the inner side wall of the interlayer in an upwardly inclined manner, the furnace bottom part 210 is in the shape of a semicircle, the middle part of the furnace bottom part 210 is fixedly connected with an oval protrusion, the cylindrical group 211 is composed of a plurality of cylindrical protrusions, the plurality of cylindrical groups 211 are located between the side wall of the furnace bottom part 210 and the oval protrusion, and the distribution and height of the plurality of cylindrical groups 211 are irregular.

[0060] Specifically, when the incinerator body 1 is in use, the driving motor 21 is started to operate as well, since the driving motor 21 is rotatably connected with the connecting shaft 22, when the output end of the driving motor 21 rotates, the connecting shaft 22 and the driving gear 23 will rotate synchronously, and then the driving gear 23 will drive the driven gear ring 24 to rotate synchronously.

[0061] Since the layered filter frame 26 located in the middle area of the incinerator body 1 is fixedly connected with the uppermost driven gear ring 24, the layered filter frame 26 will also rotate synchronously when the driving motor 21 is started, since the spiral pipe 28 is in communication with the feed inlet above the incinerator body 1 and the output port below the layered filter frame 26, respectively, and the inner diameter of the spiral pipe 28 and the output port below the layered filter frame 26 is the same as the inner diameter of the feed inlet above the incinerator body 1, the layered filter frame 26 rotating will ensure that the spiral pipe 28 feeding from above and the spiral pipe 28 discharging from below can guarantee the uniform distribution of the raw materials immediately, avoiding the accumulation of raw materials at the same position.

[0062] When the hot gas inside the incinerator body 1 flows upward and encounters the spoiler 27 kept rotating, the spoiler 27 changes the flow direction and speed distribution of the gas flow under the action of rotation, and then makes the gas flow form a vortex trend. These vortexes make the flow path of the hot gas become complex and turbulent, and are no longer a simple straight upward, thereby increasing the residence time and flow path length of the hot gas near the layered filter frame 26;

[0063] Due to the introduction of the spiral pipe 28 inside the incinerator body 1, and the spiral pipe 28 is designed in a double-layer form, when the incinerator body 1 is running, the hot air generated by the bottom combustion chamber will naturally enter the interlayer of the spiral pipe 28 due to the principle of hot air rising, and form an upward flow in the interlayer, starting the heat circulation process, reducing the heat loss to the surrounding environment. The hot gas stream entering the interlayer will encounter the flow guide spikes 29 uniformly installed on the inner side wall of the interlayer during the flow process, and the flow direction of the hot gas stream will be changed by relying on the flow guide spikes 29 and the shape of the spiral pipe 28, so that the hot gas stream continues to flow along the inner side wall of the spiral pipe 28, which makes the hot gas stream closer to the raw materials in the pipe, creating conditions for preheating the raw materials. Embodiment

[0064] Based on Embodiment 1, please refer to Figures 9 to 11 As shown in the figure, the incinerator body 1 is externally mounted with a ventilation module 12, and the ventilation module 12 is internally provided with a dynamic ventilation mechanism 3, which includes a ventilation pipe 31 communicated with the inside of the incinerator body 1. The end of the ventilation pipe 31 close to the incinerator body 1 is externally mounted with a limiting ring 32, and the limiting ring 32 is internally uniformly mounted with a plurality of ball groups 33. A connecting spring 34 is mounted between every two adjacent ball groups 33. The inner side wall of the ventilation pipe 31 is fixedly connected with a wind distribution disc 35, and the side wall of the wind distribution disc 35 is fixedly connected with a shunt column 36.

[0065] It should be noted that the two ends of the connecting spring 34 are fixedly connected with the incinerator body 1 and the limiting ring 32 respectively, the wind distribution disc 35 is composed of a plurality of fan-shaped inclined assemblies, and the outer wall of the shunt column 36 is in the form of a sharp tip.

[0066] Specifically, when the external wind force continuously flows from the ventilation duct 31, due to the characteristics of the airflow itself, the wind pressure in each direction cannot be completely consistent, and in the fluid, the flow rate is small, the pressure is small, and the flow rate is slow, the pressure is large, the airflow speed inside the ventilation duct 31 is unevenly distributed, which will cause the wind pressure in each direction to be different, and this imbalance of wind pressure will generate different directions and sizes of force on the inside of the ventilation duct 31, and because the limiting ring 32 and the ventilation duct 31 are connected through multiple ball shafts, the ball shafts can reduce the friction when the ventilation duct 31 rotates, so that it can be more flexible in the limiting ring 32. Rotate, at the same time, the connecting spring 34 introduced between the incinerator body 1 and the limiting ring 32 also provides elastic support, so when the force generated by the wind pressure makes the ventilation duct 31 deviate from the initial position, the connecting spring 34 will generate the corresponding elastic force to try to restore the ventilation duct 31 to its original position, but due to the continuous change of the wind pressure and the irregular direction, the ventilation duct 31 cannot be stabilized in a fixed position under the joint action of the wind pressure and the elastic force of the connecting spring 34, thereby generating irregular changes.

[0067] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
