[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment:

[0033] As Figures 1-6As shown in the figure, an embodiment of the present invention provides a carbon black collection device for furnace method carbon black production, including a furnace body 1, an induced draft fan 2, a filter box 3, a connecting pipe 4, a connecting frame 5, and an exhaust pipe 6. The furnace body 1 is the main equipment for carbon black generation, and its interior is provided with a carbon black generation reaction zone for completing the high-temperature cracking reaction of carbon black. An induced draft fan 2 is installed on the upper part of the furnace body 1. The function of the induced draft fan 2 is to draw out the carbon black gas flow generated in the furnace body 1 and send it into the subsequent collection system to ensure the efficient transportation of the carbon black gas flow. The connecting pipe 4 connects the outlet of the induced draft fan 2 with the inlet of the filter box 3, enabling the carbon black gas flow to smoothly enter the filter box 3 for preliminary filtration and cooling treatment. The outlet of the filter box 3 is connected to the inlet of the connecting frame 5 through another connecting pipe 4, and the connecting frame 5 further filters the carbon black dust. Finally, the exhaust pipe 6 is connected to the top of the connecting frame 5 for discharging the filtered clean gas.

[0034] Next, with reference to Figure 2 , the structure and function of the filter box 3 will be described in detail. A cooling device is provided inside the filter box 3. The cooling device includes a cooling pipe 9, and the cooling pipe 9 surrounds the inner wall of the filter box 3. The cooling medium is cooling water. By the circulating flow of the cooling water in the cooling pipe 9, the temperature of the carbon black gas flow can be effectively reduced, preventing damage to the subsequent filtering equipment by the high-temperature gas flow. A blocking column 7 is fixedly installed in the middle of the filter box 3. Connecting rods 8 are fixedly installed at both ends of the blocking column 7. The function of the connecting rods 8 is to guide the gas flow and prevent the gas flow from directly impacting the inner wall of the filter box 3, thereby improving the filtering efficiency and reducing equipment wear. When the carbon black gas flow enters the filter box 3, first through the action of the blocking column 7 and the connecting rods 8, the gas flow is dispersed and its speed is slowed down. Subsequently, the temperature of the gas flow is reduced under the cooling action of the cooling pipe 9, and then it further enters the connecting frame 5 for fine filtration.

[0035] Furthermore, with reference to Figure 3 , the structure and function of the connecting frame 5 will be described in detail. The connecting frame 5 includes an air inlet frame 13, a filter mesh plate 14, and a fixed frame 12. The air inlet frame 13 is fixedly installed on the outer wall of the furnace body 1, and a fixed frame 12 is fixedly installed on the top. The filter mesh plate 14 is installed inside the top of the fixed frame 12. The material is a high-efficiency composite material, which has excellent filtering performance and high-temperature resistance characteristics. Connecting plates 15 are installed at both ends of the filter mesh plate 14. Groove holes 16 are provided on the inner walls at both ends of the fixed frame 12. The connecting plates 15 are slidably connected to the groove holes 16, and a spring 20 is fixedly installed at one end of the connecting plate 15. The spring 20 is fixedly connected to the fixed frame 12. Through the elastic support of the spring 20, the filter mesh plate 14 can be more firmly installed in the fixed frame 12, and at the same time, it is convenient for the disassembly and replacement of the filter mesh plate 14. When the carbon black gas flow enters the connecting frame 5, through the efficient filtration of the filter mesh plate 14, the carbon black dust is effectively intercepted, and the clean gas is discharged through the exhaust pipe 6.

[0036] Particularly, with reference to Figure 4 andFigure 5 Describe in detail the structure and function of the vibration mechanism. The vibration mechanism is installed on the inner wall of the top of the connection frame 5 and is used to prevent the clogging of the filter mesh plate 14. The vibration mechanism includes a motor 17, which is fixedly installed on the outer wall of the fixed frame 12, and its vibration frequency and intensity are adjustable. The output end of the motor 17 is fixedly installed with a rotating rod 18, and cam 19s are fixedly installed on the outer rings of the front and rear ends of the rotating rod 18. When the motor 17 is started, the rotating rod 18 drives the cam 19s to rotate, and the rotational movement of the cam 19s causes the filter mesh plate 14 to vibrate, thereby effectively preventing the accumulation of carbon black dust on the filter mesh plate 14 and avoiding the clogging problem of the filter mesh plate 14 caused by dust accumulation. By adjusting the vibration frequency and intensity of the motor 17, the vibration effect can be flexibly adjusted according to the actual working conditions to ensure that the filter mesh plate 14 is always in the best working state.

[0037] In addition, refer to Figure 6 Describe in detail the structure and function of the control system. The control system is used to control the operation of the entire collection device, including the start and stop of the induced draft fan 2, the working time and frequency of the vibration mechanism, etc. The control system includes a central processing unit 21, a sensor module 22, and an execution module 10. The central processing unit 21 is responsible for data processing and instruction sending, the sensor module 22 is responsible for real-time monitoring of the operation status of the collection device, and the execution module 10 is responsible for controlling the operation of devices such as the induced draft fan 2 and the motor 17. Specifically, the central processing unit 21 obtains parameters such as temperature, pressure, and humidity in the filter box 3 and the connection frame 5 through the sensor module 22, and adjusts the operation parameters of the induced draft fan 2 and the motor 17 in real time according to these parameters. For example, when the sensor module 22 detects that the temperature in the filter box 3 is too high, the central processing unit 21 will increase the flow rate of the cooling water and lower the water temperature in the cooling pipe 9; when it detects that there is too much dust accumulation on the filter mesh plate 14, the central processing unit 21 will adjust the vibration frequency and intensity of the motor 17 to increase the vibration effect, thereby effectively cleaning the dust accumulation on the filter mesh plate 14.

[0038] A discharge port is provided at the bottom of the air inlet frame 13, and an electric valve is installed at the discharge port. The electric valve is connected to the control system and can be automatically opened or closed as needed, facilitating the discharge operation of the collected carbon black dust. When the carbon black dust in the air inlet frame 13 reaches a certain amount, the control system will issue an instruction to control the electric valve to open, and the carbon black dust will be discharged through the discharge port for subsequent processing.

[0039] In a specific embodiment, it is assumed that during the production process of furnace black, the temperature of the carbon black generation reaction zone in the furnace body 1 is 1200 °C, and the flow rate of the carbon black gas stream is 1000 m 3 / h. The operator first starts the induced draft fan 2, and the induced draft fan 2 draws out the carbon black gas flow in the furnace body 1 and sends it into the filter box 3 through the connecting pipe 4. Inside the filter box 3, the carbon black gas flow is first dispersed and its speed is reduced by the action of the blocking column 7 and the connecting rod 8, and then enters the cooling area of the cooling pipe 9. The cooling water circulates inside the cooling pipe 9 to reduce the temperature of the carbon black gas flow to about 800 °C, avoiding damage to the subsequent filtering equipment by the high-temperature gas flow. The cooled carbon black gas flow enters the connecting frame 5, and through the efficient filtration of the filter mesh plate 14, the carbon black dust is effectively intercepted, and the clean gas is discharged through the exhaust pipe 6.

[0040] To ensure the efficient operation of the filter mesh plate 14, the operator sets the vibration frequency of the motor 17 to 50 Hz and the vibration intensity to 20 N through the central processor 21 in the control system. After the motor 17 is started, the rotating rod 18 drives the cam 19 to rotate, and the rotational movement of the cam 19 causes the filter mesh plate 14 to vibrate, effectively preventing the accumulation of carbon black dust on the filter mesh plate 14. When the sensor module 22 detects that there is too much dust accumulation on the filter mesh plate 14, the central processor 21 will automatically adjust the vibration frequency and intensity of the motor 17 to increase the vibration effect, thus ensuring that the filter mesh plate 14 is always in the best working state. At the same time, the humidity sensor 11 inside the exhaust pipe 6 monitors the humidity of the discharged gas in real time. When the humidity exceeds the set value, the central processor 21 will adjust the air volume of the induced draft fan 2 to reduce the moisture content and ensure that the cleanliness of the discharged gas meets the environmental protection standards.

[0041] Furthermore, the material of the filter mesh plate 14 is a high-efficiency composite material, which has good high-temperature resistance and filtering performance. During long-term use, the filtering efficiency of the filter mesh plate 14 remains stable and it is not easily damaged. When the filter mesh plate 14 needs to be replaced, the operator only needs to slide the connecting plate 15 out of the slot hole 16, take out the filter mesh plate 14 and replace it with a new one, and the operation is simple and fast. The elastic support of the spring 20 makes the filter mesh plate 14 more firmly installed during the installation process, reducing the loosening problem caused by vibration and ensuring the stable operation of the equipment.
