Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, specifically to a hybrid furnace gasification incinerator. Background Technology

[0002] A hybrid gasification incinerator is a waste treatment device that incinerates waste by breaking it down into gas and residue. It combines gasification and incineration technologies, partially gasifying the waste before further processing it through incineration, thereby reducing the volume of waste.

[0003] The existing incinerator incineration process is as follows: first, the furnace door is opened, then the waste to be incinerated is poured into the incinerator for combustion, and then the furnace door is closed to complete the incineration.

[0004] While this method can achieve the incineration of waste, the following problems still exist: open flames are generated during the incineration process, and when the furnace door is opened and waste is poured into the incinerator, the open flames inside the furnace can easily burst out, posing a danger to the workers. Utility Model Content

[0005] This utility model proposes a hybrid furnace gasification incinerator, which solves the safety problems caused by introducing waste into the incinerator in the prior art and improves the practicality of the equipment.

[0006] The technical solution of this utility model is as follows:

[0007] Hybrid gasification incinerator, including a fixed frame,

[0008] A first combustion furnace is fixed on the fixed frame, and a second combustion chamber flue gas purification system for treating flue gas is also provided on the fixed frame. The second combustion chamber flue gas purification system includes a second combustion furnace. The top of the first combustion furnace and the top of the second combustion furnace are connected. A material conveying pipe is provided on the side wall of the first combustion furnace. A feed pipe is provided on the upper side of the material conveying pipe. A material conveying structure for transporting the material in the feed pipe to the first combustion furnace is provided inside the material conveying pipe. A stirring structure for stirring the material in the combustion furnace is provided inside the first combustion furnace.

[0009] Furthermore, the material conveying structure includes a conveying screw, which is disposed inside the material conveying pipe and rotatably connected to the material conveying pipe. A first drive motor is also fixed on the material conveying pipe, and the output shaft of the first drive motor is fixedly connected to the conveying screw.

[0010] Furthermore, a guide hopper is connected to the top of the conveying pipe, a blower is connected to the side wall of the first combustion furnace, and an oxygen supply box is also provided on the fixed frame. The oxygen supply box is connected to the first combustion furnace and the second combustion furnace.

[0011] Furthermore, the stirring structure includes a first stirring blade and a second stirring blade. A first bevel gear is fixed at the bottom of the first combustion furnace. The first bevel gear has a rotating hole, and a first rotating rod is rotatably connected in the rotating hole. A second bevel gear is fixed on the first stirring blade, and a third bevel gear is fixed on the second stirring blade. Both the second and third bevel gears mesh with the first bevel gear.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The working process of this embodiment is as follows: First, the first drive motor is started to drive the conveying screw to rotate. Then, the waste is introduced from the guide hopper into the conveying pipe and guided into the first combustion furnace for combustion by the conveying screw. At this time, the second drive motor is started, and the second and third bevel gears move on the first bevel gear, so that the first and second stirring blades revolve around the central axis of the first bevel gear while rotating on their own axis.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 2-5As shown, this embodiment proposes a hybrid flue gas incinerator, whose structure includes a fixed frame 1, a first combustion furnace 2, and a secondary combustion chamber flue gas purification system mounted on the fixed frame for treating the flue gas. The secondary combustion chamber flue gas purification system includes a second combustion furnace 9, which is fixedly mounted on the fixed frame 1. The top of the first combustion furnace 2 and the top of the second combustion furnace 9 are connected. A conveying pipe 8 is located on the side wall of the first combustion furnace 2, and a feed pipe 82 is located above the conveying pipe 8. A conveying structure is located inside the conveying pipe 8 to transport the material in the feed pipe 82 to the first combustion furnace 2. A stirring structure is located inside the first combustion furnace 2 to stir the material in the combustion furnace. In this embodiment, the first combustion furnace 2 is used to directly burn waste, while the second combustion furnace 9 is used to treat the combustible gases generated during the combustion of waste in the first combustion furnace 2. Incompletely burned gases are also discharged from the first combustion furnace 2. The second combustion furnace 9 performs secondary combustion on these gases, reducing their environmental pollution.

[0028] The stirring structure in this embodiment includes a first stirring blade 2321 and a second stirring blade 2331. A first bevel gear 231 is fixedly disposed at the bottom of the first combustion furnace 2. A rotating hole 2312 is disposed on the first bevel gear 231. A first rotating rod 251 is rotatably disposed in the rotating hole 2312. A second bevel gear 232 is fixedly disposed on the first stirring blade 2321. A third bevel gear 233 is fixedly disposed on the second stirring blade 2331. Both the second bevel gear 232 and the third bevel gear 233 mesh with the first bevel gear 231. A second rotating rod 25 is fixedly disposed between the second bevel gear 232 and the third bevel gear 233. The first rotating rod 251 and the second rotating rod 25 are fixedly connected. This design not only allows the combustion material entering from the transport pipe to be rapidly and evenly distributed in the first combustion furnace 2 under the action of the first stirring blade 2321 and the second stirring blade 2331, preventing the accumulation of combustion material from causing insufficient oxygen supply and incomplete combustion, but also, because the first stirring blade 2321 and the second stirring blade 2331 can simultaneously revolve and rotate, the combustion material in the lower layer will be flipped to the upper layer, which prolongs the contact time of the combustion material with oxygen during the movement, resulting in more complete combustion.

[0029] In this embodiment, the second drive motor 2311 is fixedly installed at the bottom of the first combustion furnace 2. The output shaft of the second drive motor 2311 is fixedly connected to the first rotating rod 251. Several vent holes 2322 are provided on the first stirring blade 2321 and the second stirring blade 2331. By providing vent holes 2322 on the first stirring blade 2321 and the second stirring blade 2331, this embodiment reduces the impact of air resistance on the first stirring blade 2321 and the second stirring blade 2331 during their movement, making the movement of the stirring blades more stable and reliable.

[0030] The material conveying structure in this embodiment includes a conveying screw 84, which is disposed inside and rotatably connected to the conveying pipe 8. A first drive motor 81 is fixedly mounted on the conveying pipe 8, and the output shaft of the first drive motor 81 is fixedly connected to the conveying screw 84. This embodiment uses the conveying screw 84 to transport combustible materials, separating the feed pipe 82 from the first combustion furnace 2. The conveying screw 84 and the conveying pipe 8 separate the open flame in the first combustion furnace 2, allowing operators to transport combustible materials to the first combustion furnace 2 without direct contact with the open flame, thus enhancing safety and reliability.

[0031] In this embodiment, the guide hopper 83 is connected to the top of the conveying pipe 8 to increase the feeding area of ​​the feed inlet, facilitating the entry of the combustible material. The blower 21 is connected to the side wall of the first combustion furnace 2 to increase airflow and improve combustion efficiency. The oxygen supply box 91 is mounted on the fixed frame 1 to provide oxygen for combustion. The oxygen supply box 91 is connected to the first combustion furnace 2 and the second combustion furnace 9. In this embodiment, the blower 21 drives the oxygen supply to flow into the first combustion furnace 2 and the second combustion furnace 9, improving the combustion efficiency of the first combustion furnace 2 and the second combustion furnace 9, resulting in more complete combustion of the combustible material.

[0032] In this embodiment, the bottom of the second combustion furnace 9 is sequentially connected to a cooling box 3, a cyclone box 4, a bag filter box 5, and an activated carbon adsorption box 6. The exhaust pipe 7 is connected to the top of the activated carbon adsorption box 6. Several spray elements 31 are installed inside the cooling box 3. The preferred spray element 31 in the cooling box 3 sprays limestone slurry, which not only neutralizes the acidic gases produced by the first combustion furnace 2 and the second combustion furnace 9, but also effectively and quickly lowers the temperature of the flue gas, facilitating subsequent flue gas treatment. The cyclone box 4 used in this embodiment separates particulate matter mixed in the gas using centrifugal force generated by the rotating airflow. The particulate matter is collected at the bottom of the cyclone box 4, while the separated flue gas is discharged from the top. The bag filter box 5 used in this embodiment captures and collects dust and particles in the flue gas through a filter bag. The cleaned airflow is discharged through the filter bag, thereby reducing air pollution. The activated carbon adsorption box 6 in this embodiment is used to remove volatile organic compounds (VOCs), odorous gases, and other pollutants from the gas. The cyclone box 4, bag filter box 5, and activated carbon adsorption box 6 used in this embodiment are all cyclones in the prior art, and will not be described in detail in this embodiment.

[0033] In this embodiment, the combustion chamber 23 and the flue gas guiding chamber 22 are located within the first combustion furnace 2. The combustion chamber 23 has a cylindrical structure. The flue gas guiding chamber 22 has a frustum-shaped structure, designed to allow more flue gas to accumulate at the top of the flue gas guiding chamber 22, facilitating the entry of flue gas into the second combustion furnace 9. A partition plate 24 is located between the combustion chamber 23 and the flue gas guiding chamber 22, and the partition plate 24 has flue gas guiding holes 241. Since the flue gas generated in the combustion chamber 23 contains fixed combustion materials, these fixed combustion materials will remain on the partition plate 24 after contacting it, while the flue gas will enter the second combustion furnace 9 through the flue gas guiding holes 241. This design of the partition plate 24 can reduce the entry of fixed impurities into the second combustion furnace 9.

[0034] The working process of this embodiment is as follows: First, the first drive motor 81 is started, which drives the conveying screw 84 to rotate. Then, the waste is introduced from the guide hopper 83 into the conveying pipe and then introduced into the first combustion furnace 2 for combustion through the conveying screw 84. At this time, the second drive motor 2311 is started, and the second bevel gear 232 and the third bevel gear 233 move on the first bevel gear 231, so that the first stirring blade 2321 and the second stirring blade 2331 revolve around the central axis of the first bevel gear 231 while rotating on their own axis. At this time, the combustion gas flows into the second combustion furnace 9 under the action of the air pump to continue to be fully combusted. After passing through the cooling box 3 for cooling, the cyclone box 4 for separation, the bag dust collector box 5 for dust removal and the activated carbon adsorption box 6 for filtration, it is finally discharged from the exhaust pipe 7.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
