Description

Technical Field

[0001] This utility model relates to the field of carbonization equipment technology, and in particular to a gas-carbon cogeneration device specifically designed for high-moisture waste. Background Technology

[0002] The gas-coke cogeneration carbonization furnace is an environmentally friendly biomass pyrolysis equipment that can simultaneously produce biochar and combustible pyrolysis gas. It is a dry distillation process carried out in an oxygen-free or oxygen-deficient environment. The pyrolysis gas is purified and reused as a carbonization heat source, realizing energy recycling and cascade utilization.

[0003] To fully utilize the high-temperature flue gas generated during carbonization, the exhaust flue gas is usually collected, and the raw materials to be carbonized are dried. For example, the existing Chinese utility model patent with publication number CN222160074U, "A Carbonization Furnace Flue Gas Recycling and Reuse Equipment," allows the flue gas generated by the carbonization furnace to be used as fuel to transport to the carbonization furnace and the pulverizing and drying equipment through the setting of flue gas pipelines. However, after the pulverized raw materials are dried, the raw materials will accumulate at the bottom of the pulverizing and drying equipment due to gravity during the transport of the raw materials, forming a dense material layer. This makes it difficult for hot air to penetrate the accumulation area, resulting in uneven heat and mass transfer between the inside and the surface of the material layer. That is, the surface raw materials are prone to over-drying or even coking, while the internal raw materials retain moisture due to insufficient heat contact. Ultimately, this results in large fluctuations in the moisture content and uneven quality of the dried product. At the same time, the accumulated raw materials slow down the movement speed, and some particles remain in the equipment for a long time, which will hinder the full contact between the subsequent raw materials and the hot air, further reducing the drying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a gas-carbon cogeneration device specifically for high-humidity waste, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gas-carbon cogeneration device specifically designed for high-moisture waste includes a carbonization furnace housing and a vertical dryer. Several carbonization chambers are fixedly connected inside the carbonization furnace housing, and several burners are fixedly connected to both sides of the carbonization furnace housing. A first exhaust pipe is fixedly connected to the carbonization furnace housing. The vertical dryer also includes a collection box, and a drying box is fixedly connected to the collection box. A fan is fixedly connected to one side of the drying box and communicates with the drying box cavity. The side of the fan away from the drying box is connected to the first exhaust pipe via a pipeline. A second exhaust pipe is fixedly connected to the pipe. Several bushings are fixedly connected to both sides of the drying chamber. A sieve frame is provided inside the drying chamber. Several first mounting shafts are fixedly connected to both sides of the sieve frame. The first mounting shafts are inserted into one of the bushings. Several flow dividers are provided inside the drying chamber located below the sieve frame. Second mounting shafts are fixedly connected to both sides of the flow dividers. One side of the second mounting shaft is also inserted into one of the bushings. Several first mounting shafts are fixedly connected to one side of the flow divider with side plates.

[0007] As a further preferred embodiment of this utility model, a collection hopper is fixedly connected inside the carbonization furnace box, and a spiral discharger is fixedly connected to the bottom of the collection hopper. The spiral discharger is electrically connected to the controller outside the drying box via a connecting line, thereby discharging the biomass raw materials accumulated in the collection hopper.

[0008] As a further preferred embodiment of this utility model, a feed inlet is provided on the rear side of the drying chamber located above the screen frame. A guide plate is fixedly connected inside the drying chamber between the feed inlet and the screen frame. The guide plate is inclined towards the center of the drying chamber, so that after the external raw material conveying device conveys the raw material to be dried to the guide plate through the feed inlet, it can be buffered by the guide plate and slide down onto several screen frames.

[0009] As a further preferred embodiment of this utility model, a plurality of screen frames are fixedly connected inside the screen frame, and screens are fixedly connected to the screen frames. Thus, through the vibration transmission of the vibrating motor, the side plate, and the first mounting shaft, the biomass raw materials falling onto the screen frames can be shaken apart and fall through the channel between two adjacent screen frames, while also buffering the biomass raw materials and increasing the drying time. A first stud is fixedly connected to one side of the first mounting shaft on one side of the screen frame, providing a foundation for the installation of the side plate. A first compression spring is fitted onto the first mounting shaft located between the screen frame and the drying box.

[0010] As a further preferred embodiment of this utility model, several sleeve plates are fixedly connected to both sides of the drying chamber located below the sieve frame. Several multi-layered and staggered diversion hoods are arranged inside the drying chamber, with each side of the diversion hood inserted into one of the sleeve plates. The longitudinal cross-section of the diversion hood is triangular, and the inner and outer surfaces of the diversion hood are covered with screens. Flow buffer frames are fixedly connected to the front and rear sides of the diversion hood, and screens are also laid on the flow buffer frames. This buffers the impact of biomass raw materials between the diversion hoods. At the same time, the vibration of the vibration motor enables the diversion hoods to swing left and right, and the flow buffer frames further disperse the biomass raw materials, allowing them to fully contact the hot air inside the drying chamber and improve drying efficiency.

[0011] As a further preferred embodiment of this utility model, a second stud is fixedly connected to one side of the second mounting shaft on one side of the diversion hood, which, together with the first stud, provides multiple mounting bases for the side plate. A second compression spring is fitted onto the second mounting shaft located between the diversion hood and the drying oven.

[0012] As a further preferred embodiment of this utility model, the side plate is inserted and connected to several first studs and second studs and fixed with nuts. A bracket is fixedly connected to one side of the side plate, and a vibration motor is fixedly connected to the bracket. The vibration motor is electrically connected to a controller on the outside of the drying chamber through a connecting wire. Thus, the horizontally placed vibration motor, in conjunction with the side plate, synchronously drives the screen frame and several diversion hoods to vibrate left and right at high frequency in the drying chamber, thereby realizing the dispersal and shaking of biomass raw materials.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the vibrating screen frame and several staggered diversion hoods can break the gravity accumulation of raw materials at the bottom of the equipment, allowing the raw materials to form a uniformly dispersed fluidized state. This ensures that the hot air is in full contact with each particle of raw material, greatly improving the heat and mass transfer efficiency. At the same time, the smooth movement of the raw materials within the equipment can reduce the difference in residence time, thereby reducing energy consumption and increasing the throughput per unit time.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-7 As shown, this utility model provides a gas-carbon cogeneration device specifically for high-moisture waste, including a carbonization furnace body 1 and a vertical dryer 5. Several carbonization chambers 2 are fixedly connected inside the carbonization furnace body 1, and several burners 3 are fixedly connected to both sides of the carbonization furnace body 1. A first exhaust pipe 4 is fixedly connected to the carbonization furnace body 1. The vertical dryer 5 also includes a collection box 26, on which a drying box 6 is fixedly connected. A fan 7 is fixedly connected to one side of the drying box 6 and communicates with the cavity of the drying box 6. The side of the fan 7 away from the drying box 6 is connected to the first exhaust pipe 4 via a pipe. The first exhaust pipe 4... A second exhaust pipe 8 is fixedly connected to the top. Several bushings 11 are fixedly connected to both sides of the drying box 6. A screen frame 10 is provided inside the drying box 6. Several first mounting shafts 12 are fixedly connected to both sides of the screen frame 10. The first mounting shafts 12 are inserted into one of the bushings 11. Several diversion hoods 13 are provided inside the drying box 6 located below the screen frame 10. Second mounting shafts 14 are fixedly connected to both sides of the diversion hoods 13. One side of the second mounting shafts 14 is also inserted into one of the bushings 11. Several first mounting shafts 12 are fixedly connected to one side of the diversion hoods 13 with side plates 15.

[0025] like Figures 2-3As shown, a hopper 16 is fixedly connected inside the carbonization furnace box 1, and a spiral feeder 17 is fixedly connected to the bottom of the hopper 16. The spiral feeder 17 is electrically connected to the controller outside the drying box 6 through a connecting line, so that the biomass raw materials accumulated in the hopper 16 can be discharged.

[0026] like Figure 3 , Figures 5-6 As shown, a feed inlet 9 is provided on the rear side of the drying chamber 6 located above the screen frame 10. A guide plate 27 is fixedly connected inside the drying chamber 6 between the feed inlet 9 and the screen frame 10. The guide plate 27 is inclined towards the center of the drying chamber 6, so that after the external raw material conveying device conveys the raw material to be dried through the feed inlet 9 to the guide plate 27, it can be buffered by the guide plate 27 and slide onto several screen frames 18. Several screen frames 18 are fixedly connected inside the screen frame 10, and screens are fixedly connected to the screen frames 18. Thus, through the vibration transmission of the vibration motor 25, the side plate 15, and the first mounting shaft 12, the biomass raw materials falling onto the screen frame 18 can be shaken apart and fall through the channel between two adjacent screen frames 18, while also buffering the biomass raw materials and increasing the drying time. The first mounting shaft 12 on one side of the screen frame 10 is fixedly connected to a first stud 19, providing a foundation for the installation of the side plate 15. The first mounting shaft 12 located between the screen frame 10 and the drying box 6 is fitted with a first compression spring 20.

[0027] like Figures 3-4 , Figure 7As shown, several sleeve plates 28 are fixedly connected to both sides of the drying chamber 6 located below the screen frame 10. Several multi-layered and staggered diversion hoods 13 are arranged inside the drying chamber 6, with each diversion hood 13 inserted into one of the sleeve plates 28 on each side. The longitudinal cross-section of the diversion hood 13 is triangular, and the inner and outer surfaces of the diversion hood 13 are covered with screens. Slow-flow frames 21 are fixedly connected to the front and rear sides of the diversion hood 13, and screens are also laid on the slow-flow frames 21. This buffers the impact of the biomass raw material between the diversion hoods 13. Simultaneously, the vibration of the vibration motor 25 enables the diversion hood 13 to swing left and right, and the slow-flow frames 21 further disperse the biomass raw material, allowing it to fully contact the hot air inside the drying chamber 6, improving drying efficiency and diverting the flow. A second stud 22 is fixedly connected to one side of the second mounting shaft 14 on one side of the cover 13. Together with the first stud 19, it provides multiple mounting bases for the side plate 15. The second mounting shaft 14, located between the diversion cover 13 and the drying chamber 6, is fitted with a second compression spring 23. The side plate 15 is inserted and connected to several first studs 19 and second studs 22 and fixed with nuts. A bracket 24 is fixedly connected to one side of the side plate 15. A vibration motor 25 is fixedly connected to the bracket 24. The vibration motor 25 is electrically connected to the controller outside the drying chamber 6 through a connecting wire. Thus, the horizontally placed vibration motor 25, together with the side plate 15, synchronously drives the screen frame 10 and several diversion covers 13 to vibrate left and right at high frequency in the drying chamber 6, thereby realizing the dispersal and shaking of biomass raw materials.

[0028] It should be noted that this utility model is a gas-coke cogeneration device specifically designed for high-moisture waste. When drying the pulverized biomass raw material, the raw material is first fed into the drying chamber 6 through the inlet 9 via a feeding device. Then, after being buffered and guided by the guide plate 27, it falls onto the screens of several screen frames 18 of the screen frame 10. At this time, the vibrating motor 25 runs continuously, and its vibration is transmitted to the side plate 15 through the bracket 24, and then synchronously transmitted to the first mounting shaft 12 and the second mounting shaft 14, causing the screen frame 10 and the diversion hood 13 to vibrate at high frequency left and right within the bushing 11. Combined with the elastic buffering of the first compression spring 20 and the second compression spring 23, the screen frame 10 and the diversion hood 13 maintain stable vibration. In the dynamic state, the vibrating screen frame 18 shakes the raw material apart, while the multi-layered staggered diversion hood 13 forms an impact buffer for the falling raw material. Its triangular structure and the screens on the inner and outer surfaces, together with the screen barrier of the slow-flow frame 21, further break up the raw material clumps, so that the raw material forms a uniform fluidized state. Simultaneously, the carbonization chamber 2 in the carbonization furnace box 1 performs carbonization under the action of the burner 3. The high-temperature flue gas generated in the carbonization furnace box 1 is discharged through the first exhaust pipe 4 and drawn into the drying box 6 by the fan 7. The hot flue gas fully contacts the dispersed raw material in the drying box 6, quickly removing the moisture from the raw material. The dried raw material falls into the collection box 26 for collection and can then be sent to the carbonization chamber 2 for carbonization.
