Modification can improve its adsorption performance for certain pollutants; it can also endow it with catalytic properties and enhance its removal capacity for specific substances; and it can be used to prepare activated carbon from waste rice husks.

[0034] Specifically, in the modified rice husk biochar regeneration fluidized bed reactor, separator 201 achieves efficient separation by working in conjunction with tank 1.

[0037] Working Principle: The integrated fluidized bed reactor based on modified rice husk biochar is a highly efficient device for the degradation of multiple organic pollutants, including Acid Red and Malachite Green. Tank 1 serves as the main load-bearing structure of the entire device, with reaction tank 3 firmly fixed to its inner wall. Reaction tank 3 is the core reaction area of ​​the entire device, where key pollutant degradation reactions take place. The activated carbon is prepared from waste rice husks through a process that modifies it to enhance its degradation efficiency for organic pollutants. The waste rice husks are first carbonized under specific conditions, and then pyrolyzed at high temperature to remove volatiles, thus producing high-performance activated carbon with stronger adsorption capacity for Acid Red and Malachite Green. In addition to its degradation capabilities, the top of the outer wall of the reaction tank 3 is fixedly connected to a conduit 4, which guides some of the gas and liquid generated during the reaction in the reaction tank 3 to other areas of the tank body 1 for subsequent treatment. A perforated pipe 5 is fixedly connected to the bottom of the outer wall of the tank body 1, and a filter screen 6 is fixedly connected to the bottom of the outer wall of the perforated pipe 5. The perforated pipe 5 is mainly used to introduce the gas required for the reaction into the tank body 1, while the filter screen 6 effectively prevents solid impurities from entering the perforated pipe 5, ensuring smooth gas delivery. Feed pipes 7 are fixedly connected to both the front and rear of the outer wall of the tank body 1. Through the feed pipes 7, wastewater containing various organic pollutants such as acid red and malachite green is introduced into the device. This wastewater will react with the modified rice husk biochar inside the device to achieve the degradation of organic pollutants. A slag discharge pipe 8 is fixedly connected to the bottom of the outer wall of tank 1. After the reaction is completed, the remaining solid waste and other substances in the device can be discharged through the slag discharge pipe 8. A connecting pipe 9 is connected to the top of the outer wall of tank 1. The connecting pipe 9 is fixedly connected to the top of the outer wall of conduit 4, so that the substances drawn out of the reaction tank 3 through conduit 4 can be further distributed or processed in tank 1 through the connecting pipe 9. An air inlet pipe 2 10 is fixedly connected to the four sides of the outer wall of reaction tank 3. Air inlet holes 11 are opened at equal intervals on the outer wall of air inlet pipe 2 10. Air inlet pipe 2 10 is mainly used to accurately deliver specific gases into reaction tank 3. These gases enter reaction tank 3 evenly through air inlet holes 11 and come into full contact with the modified rice husk biochar and organic pollutant wastewater in reaction tank 3, promoting the reaction. The introduced gas participates in the oxidative degradation reaction of organic pollutants, providing the necessary environmental conditions for the biochar regeneration process. A ventilation pipe 12 is installed on the left side of the outer wall of the tank 1. A rotating shaft 14 is rotatably connected to the middle of the inner wall of the ventilation pipe 12. A fan blade 15 is fixedly connected to the bottom of the outer wall of the rotating shaft 14. When the rotating shaft 14 rotates, the fan blade 15 rotates accordingly, generating airflow and realizing the flow of gas in the ventilation pipe 12, providing a good gas exchange environment inside the device. At the same time, stirring blades 13 are fixedly connected to the four sides of the outer wall of the rotating shaft 14. The stirring blades 13 can stir the substances in the ventilation pipe 12 during the rotation of the rotating shaft 14, enhancing the mixing effect between the gas and other substances. A vent pipe 16 is fixedly connected to the four sides of the outer wall of the ventilation pipe 12.Ventilation pipe 16 guides the gas in ventilation pipe 12 to other parts of the device to meet the gas requirements of different areas. A fixing bracket 17 is fixedly connected to the bottom of the outer wall of ventilation pipe 12. Fixing bracket 17 is fixedly connected to the bottom left side of tank body 1, stabilizing ventilation pipe 12 and ensuring its stability during device operation. After the modified rice husk biochar becomes saturated, it can be regenerated through a regeneration process to achieve efficient and cyclical operation of the device.

[0038] In the integrated fluidized bed reactor device for regeneration based on modified rice husk biochar, the separator 201 plays a crucial separation role. It is fixedly connected to the tank 1 and works in conjunction with the tank to achieve efficient separation. A funnel 202, fixedly connected to the top of the outer wall of the separator 201, is mainly used to guide the mixture to be separated into the separator 201. When the mixture containing ash and other substances flows through the funnel 202, the flow rate is slowed down and the distribution becomes more uniform under the guidance of the funnel's shape, preparing for the subsequent separation process within the separator 201. The exhaust pipe 203, connected to the top of the outer wall of bucket 202, plays a crucial role in discharging the separated gas. After separation is completed inside separator 201, the lighter gas components flow upward and exit separator 201 through exhaust pipe 203, entering subsequent gas processing stages or being directly discharged. The rotating pipe 204, fixedly connected to the middle of the inner wall of separator 201, is one of the core components for achieving efficient separation. When the mixture flows into separator 201, due to the centrifugal force generated by the upward rotation, different components in the mixture flow will have different motion trajectories due to density differences. Under centrifugal force, denser ash particles are thrown towards the inner wall of separator 201, while lighter gas and other suspended fine particles move near the central area of ​​rotating tube 204. An inlet pipe 205 connected to one side of the outer wall of separator 201 is used to introduce a specific gas into separator 201. The introduction of this gas further assists the separation process, making it easier for ash particles to settle and separate. A valve 207 installed at the bottom of the outer wall of inlet pipe 205 allows for flexible control of the gas flow rate and timing. Operators can adjust the flow rate and timing based on the conditions within separator 201. In terms of actual separation, the gas flow rate of the inlet pipe 205 is precisely controlled by adjusting valve 207 to achieve the best separation effect. The ash discharge pipe 206 installed at the bottom of the outer wall of separator 201 is used to remove the ash that settles at the bottom of separator 201 after separation. Under the action of centrifugal force of rotating pipe 204 and with the assistance of gas introduced through inlet pipe 205, the ash particles gradually settle to the bottom of separator 201 and are discharged through ash discharge pipe 206. Ash discharge pipe 206 can be connected to ash collection device for centralized treatment or recycling of the separated ash.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
