Description

Technical Field

[0001] The utility model relates to the technical field of waste incineration equipment, in particular to an incinerator for high-humidity waste. Background Technique

[0002] With the acceleration of the urbanization process and the expansion of agricultural production, high-humidity waste (such as wet garbage, straw, etc.) has increasingly become an important environmental problem. In traditional treatment methods, these high-humidity wastes are usually piled up in the fields waiting for natural decomposition or directly burned in the open air. However, these methods have obvious defects. Open-air burning not only releases a large amount of harmful gases and dust, seriously affecting air quality, but also poses a fire hazard. Piling treatment is prone to the corruption of waste and the breeding of germs, bringing potential risks to the environment and public health.

[0003] In recent years, with the improvement of environmental awareness and the strict implementation of relevant laws and regulations, traditional waste treatment methods have been gradually restricted. In order to effectively solve the problem of high-humidity waste treatment, incineration technology, as a common treatment method, has been widely used. For example, the patent with the publication number CN106171848B discloses a garbage incinerator, but there are often many challenges in the incineration process for treating high-humidity waste. Especially for high-water-content media such as wet garbage and straw, the evaporation of water consumes a large amount of heat during the incineration process, thereby reducing the temperature of the incinerator, resulting in incomplete combustion and low efficiency. In addition, a large amount of dust and residues may be generated during the incineration process, and an effective collection and treatment mechanism is required to reduce the impact on the environment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] The present utility model provides a technical solution: a high-humidity waste incinerator, as shown in the accompanying Figure 2As shown in the figure, it includes an incinerator body 1. A feed hopper 2 is provided on the left side of the incinerator body 1. Inside the incinerator body 1, there are multiple groups of grate mechanisms 3. An inclined plate 4 is arranged at the upper end of the grate mechanism 3. At the bottom right side of the incinerator body 1, there is a rotary incinerator 5. A blower 6 is provided at the upper end of the rotary incinerator 5. A wind guiding plate 7 is arranged at the lower end of the blower 6. A screw conveyor mechanism 8 is provided at the bottom of the incinerator body 1. An ignition furnace 9 is arranged at the lower end of the grate mechanism 3. A residue collection tank 10 is provided on the right side of the rotary incinerator 5. Multiple dust collection mechanisms 11 are arranged at the lower end of the grate mechanism 3. A smoke outlet 12 is provided at the upper end of the rotary incinerator 5.

[0032] The incinerator body 1 is the main structure of the entire wet waste incinerator, which houses and supports all other components. The feed hopper 2 is located on the left side of the incinerator body 1 and is used to load wet waste and other materials to be incinerated. The grate mechanism 3 is arranged inside the incinerator body 1 and is a platform composed of a series of metal plates or other refractory materials, which is used to support the wet waste materials. These grates can be movable or fixed, allowing air to flow from below to assist combustion. The inclined plate 4 is located at the upper end of the grate mechanism 3 and is inclined at an angle of 30°, which is used to guide the hot air flow at the lower end to the position of the feed port, increasing the temperature at the upper end, enabling the wet waste to quickly dehydrate and burn, thus promoting more efficient combustion. The rotary incinerator 5 is located at the bottom right side of the incinerator body 1, which is used to ensure uniform combustion and can better control the combustion process and ash discharge. The blower 6 is provided at the upper end of the rotary incinerator 5 and is used to supply an appropriate amount of air into the incinerator. Oxygen is an essential factor in the combustion process. The blower 6 ensures that there is enough oxidant in the combustion process, making the combustion more efficient and complete. The wind guiding plate 7 is located at the lower end of the blower 6, and its function is to guide the air blown by the blower 6 to specific areas, optimizing the air flow path, improving the thermal efficiency, and ensuring that the air can flow to the parts in the furnace that need it, thereby improving the combustion effect. The screw conveyor mechanism 8 is provided at the bottom of the incinerator body 1 and is a device for transporting materials in a horizontal or inclined direction. It usually consists of a spiral blade and a rotating shaft, which is used to remove the ash. The ignition furnace 9 is arranged at the lower end of the grate mechanism 3 and is a device used to ignite the materials in the furnace. It is used as an auxiliary ignition during the incineration process to ensure a continuous and stable combustion process. The residue collection tank 10 is provided on the right side of the rotary incinerator 5 and is used to collect the remaining residues and unburned materials after combustion for further treatment or disposal as waste. The dust collection mechanism 11 is arranged at the lower end of the grate mechanism 3 and is an opening in the incinerator for discharging the ash generated during combustion. The accumulated ash can be removed regularly or continuously during the operation of the incinerator to ensure the combustion efficiency. The smoke outlet 12 is provided at the upper end of the rotary incinerator 5 and is used to discharge the flue gas generated during combustion.

[0033] When the blower 6 is working, the generated air is guided by the wind guiding plate 7 and moves upward along the inclined plate 4 towards the upper part of the furnace body, forming the effect of hot gas rising. This design utilizes the thermodynamic principle that hot air rises and cold air sinks, thereby forming a natural heat convection cycle inside the incinerator. Optimization of temperature control: By controlling the wind force of the blower 6 and adjusting the angle of the wind guiding plate 7, the temperature and air flow direction inside the rotary incinerator 5 can be finely regulated to adapt to different combustion requirements and material characteristics. This is very important for ensuring safe and stable operating conditions and meeting environmental protection emission standards.

[0034] The grate mechanism 3 includes a fixed grate 31 and a movable grate 32. A plurality of connecting rods 33 are fixed to the lower end of the movable grate 32. A push rod 34 is clamped to the lower end of the connecting rod 33. A cylinder 35 is fixedly connected to the left side of the push rod 34. A connecting grate 36 is provided between each group of grate mechanisms 3; the fixed grate 31 and the movable grate 32 are arranged in a stepped manner in groups of two. A scraping block 311 is provided at the right bottom of the fixed grate 31, and through ventilation holes 312 are provided on the surface of the fixed grate 31.

[0035] The fixed grate 31 and the movable grate 32 are used to support and hold the position of the material to be burned. The fixed grate 31 is fixed in position, while the movable grate 32 can move, which is achieved through the mechanical action of the connecting rod 33 and the push rod 34. This design allows the material to be agitated during the combustion process, exposing more fresh surfaces to promote more complete combustion. The connecting rod 33 connects the movable grate 32 to the push rod 34, and the push rod 34 is driven by the cylinder 35, enabling the movable grate 32 to move back and forth, thereby allowing materials such as wet garbage to be turned over, ensuring uniform combustion, and reducing the possibility of blockage and incomplete combustion in the furnace. The connecting grate 36 is located between each group of grate mechanisms 3, used to support the heat load of the upper grate mechanism, and also plays a role in heat transfer and heat equalization, contributing to the temperature balance and consistency of the entire combustion process. Stepped setting: The fixed grate 31 and the movable grate 32 are arranged in a stepped manner in groups of two, and this structure helps to promote more effective air circulation and heat energy utilization. When the hot gas rises, it passes through different levels of grates, which can better dry and preheat the material, thereby improving the overall combustion efficiency.

[0036] The combined use of the movable grate and the fixed grate not only improves the combustion efficiency but also reduces the frequency of manual intervention. The cylinder-controlled push rod - movable grate system provides reliable mechanical agitation, ensuring continuous and uniform combustion. The stepped structure and the design of the ventilation holes further optimize the thermal efficiency and combustion adequacy. The self-cleaning function of the scraping block and the air supply / temperature control function of the ventilation holes both enhance the operational stability and durability of the equipment.

[0037] The screw conveyor mechanism 8 includes a conveying pipe body 81. A conveying motor 82 is fixed to the left side of the conveying pipe body 81. A screw blade 83 is fixed on the output shaft of the conveying motor 82. An ash discharge cavity 84 is arranged at the bottom of the conveying pipe body 81. The dust collection mechanism 11 penetrates into the interior of the conveying pipe body 81. The conveying pipe body 81 is a long cylindrical structure made of high-temperature resistant materials and is used to accommodate and guide the conveying path of materials. The conveying motor 82 fixed to the left side of the conveying pipe body 81 is the power source of the screw conveyor mechanism. According to the design requirements, the conveying motor 82 can rotate forward or backward to control the rotation direction of the screw blade 83 and discharge the ashes through its spiral shape. Ash discharge cavity 84: An ash discharge cavity 84 is arranged at the bottom of the conveying pipe body 81, which is a cavity for discharging ashes.

[0038] The dust collection mechanism 11 includes a collection hopper 111 arranged at the lower end of the grate mechanism 3. A conveying channel 112 is fixed to the lower end of the collection hopper 111. An ash outlet 113 is arranged at the lower end of the conveying channel 112, and the ash outlet 113 penetrates into the interior of the conveying pipe body 81. The collection hopper 111 is located at the lower end of the grate mechanism 3 and is a container for capturing and accumulating the ashes generated during the incineration process. The opening usually faces upward so that the ashes and dust can naturally fall during the combustion process. A conveying channel 112 is fixed to the lower end of the collection hopper 111, which is an intermediate structure connecting the collection hopper 111 and the ash outlet 113. An ash outlet 113 is arranged at the lower end of the conveying channel 112, which is an opening for discharging the accumulated ashes. The ash outlet 113 can be further designed with a valve so that the operator can control the discharge time and amount of the ashes. The ash outlet is used to achieve the automatic conveying and discharge of the ashes.

[0039] The wet waste incinerator of the present invention realizes the efficient combustion and treatment of wet waste and other wastes through the following steps:

[0040] 1. Feeding: The high-humidity medium enters the incinerator through the feeding hopper 2 located on the left side of the incinerator body.

[0041] 2. Material movement and preliminary combustion: After the high-humidity medium entering the incinerator reaches the grate mechanism 3, the push rod 34 drives the movable grate 32 to move horizontally back and forth. When the movable grate 32 extends, the waste on the upper surface of the fixed grate is pushed onto the upper surface of another movable grate 32 below, and when the movable grate 32 retracts, the waste on the upper surface of the movable grate 32 is scraped off by the fixed grate 31 above. This is repeated, and the waste is gradually dispersed and conveyed obliquely downward along the grate. During this process, the flame in the bottom ignition furnace continuously ignites the wet waste on the left grate, causing it to burn preliminarily.

[0042] 3. Step-by-step Combustion and Heat Utilization: The wet waste burns step by step downward in the incinerator and is fully burned during this process. The rotary incinerator set at the right bottom can not only burn out the wet waste and reduce residues, but also drive the hot air to the wet waste that starts burning at the leftmost side through the design of the blower and the inclined plate, improving the heating efficiency. The combination of the blower and the wind guiding plate provides an appropriate amount of air for combustion and ensures the effective circulation of the hot air flow, thereby improving the combustion efficiency.

[0043] 4. Ash and Residue Disposal: The ash generated during the combustion process falls through the ventilation holes 312 of the grate mechanism 3 and is collected in the dust collection mechanism 11. The dust collection mechanism 11 discharges the ash through the conveying channel and the ash outlet, and the ash outlet penetrates into the conveying pipe body of the screw conveying mechanism to achieve continuous disposal of the ash.

[0044] 5. Exhaust Gas Emission: A smoke outlet is provided on the upper right side of the incinerator body for discharging the flue gas generated by combustion.

[0045] Through the above design and working process, the wet waste incinerator of the present invention can efficiently process wet waste with a high water content, fully utilize the heat generated by combustion, improve the combustion efficiency, and achieve environmental protection treatment of ash and exhaust gas.

[0046] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
