Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , this embodiment provides a technical solution: an organic waste gas treatment device with biological packing, including a treatment tank 1;

[0020] Treatment tank 1: At the lower end inside it, there are two support mesh plates 1-2 arranged in parallel. Between the two support mesh plates 1-2, there is a biological filler layer 3. The biological filler layer 3 is a ceramsite biological filler layer. Organic waste gas and air pass through the lower support mesh plate 1-2 and enter the interior of the gaps in the biological filler layer 3. Microorganisms growing on the surface of the biological filler layer 3 decompose the organic matter in the waste gas into inorganic substances, and then the gas passes through the upper support mesh plate 1-2 and continues to flow upward. On the left side of the treatment tank 1, there is a blower 4. At the lower end inside the treatment tank 1, there is an annular air pipe 5. The air outlet end of the blower 4 extends into the interior of the treatment tank 1 and is communicated with the interior of the annular air pipe 5. Aeration discs 6 are arranged at the air outlet holes on the outer arc surface of the annular air pipe 5. Air and organic waste gas enter the interior of the blower 4 through two air inlet chambers, and then are output to the interior of the annular air pipe 5, and then are dispersed and flow into the interior of the treatment tank 1 through the aeration discs 6. The air inlet end of the blower 4 is provided with a mixing seat 9. At the front end of the mixing seat 9, there are two air inlet chambers. Connect the external organic waste gas pipe to the air inlet chamber at the lower side of the front surface of the mixing seat 9, and connect the upper air inlet chamber to the external air pipeline. The blower 4 sucks air from the mixing seat 9. Inside the mixing seat 9, there is a sliding connection with a baffle 10. On the left side surface of the treatment tank 1, there is a control switch group 15. The input end of the blower 4 is electrically connected to the output end of the control switch group 15. The input end of the control switch group 15 is electrically connected to an external power supply. Inside the sliding holes on the upper surface of the mixing seat 9, there are sliding connections with sliding columns 11. The lower ends of the sliding columns 11 are fixedly connected to the upper surface of the baffle 10. Between the upper ends of the two sliding columns 11, there is a support seat 12. In the middle of the support seat 12, there is a threaded connection with a lead screw 13. The lower end of the lead screw 13 is rotatably connected to the circular hole on the upper surface of the mixing seat 9. The lead screw 13 drives the baffle 10 to move downward through the support seat 12 and the sliding columns 11. The lower end of the baffle 10 gradually covers the lower air inlet chamber, thereby reducing the intake volume of organic waste gas and increasing the intake volume of air, providing more oxygen for microorganisms, and facilitating the high-quality treatment of high-concentration organic waste gas. The upper end of the lead screw 13 is provided with a handwheel 14. Rotate the handwheel 14, and the handwheel 14 drives the lead screw 13 to rotate. On the left end of the treatment tank 1, there is a nutrient solution pump 16. In the middle of the treatment tank 1, there is an annular water pipe 17. The liquid outlet pipe of the nutrient solution pump 16 extends into the interior of the treatment tank 1 and is communicated with the interior of the annular water pipe 17. The input end of the nutrient solution pump 16 is electrically connected to the output end of the control switch group 15. At the liquid outlet holes on the lower surface of the annular water pipe 17, there are atomizing nozzles 18. Connect the liquid suction end of the nutrient solution pump 16 to the nutrient solution. The nutrient solution pump 16 pumps the nutrient solution into the interior of the annular water pipe 17, and then atomizes and sprays it through the atomizing nozzles 18, and then passes through the upper support mesh plate 1-2 and flows to the surface of the biological filler layer 3, providing nutrients for the growth of microorganisms. The excess nutrient solution passes through the upper and lower support mesh plates 1-2 and enters the interior of the treatment tank 1. At the upper end inside the treatment tank 1, there is a support mesh plate 2-19. On the upper surface of the support mesh plate 2-19, there is an activated carbon layer 20. The gas passes upward through the support mesh plate 2-19 and the activated carbon layer 20 and is discharged to the outside.The activated carbon layer 20 adsorbs the organic substances in the waste gas, so as to achieve the purpose of purifying the waste gas. An overflow pipe 7 is provided at the lower end of the treatment tank 1. The lowest point of the outer arc surface at the upper end of the overflow pipe 7 is higher than the upper surface of the aeration disc 6. A valve 8 is provided in the middle of the overflow pipe 7. As the nutrient solution accumulates, the liquid level of the nutrient solution is higher than the overflow pipe 7, and the nutrient solution is discharged to the outside through the overflow pipe 7. Furthermore, the aeration disc 6 will be immersed in the interior of the nutrient solution. The nutrient solution wets the organic waste gas and air, facilitates the growth of microorganisms by carrying nutrients and the treatment of organic substances. When cleaning is required, the valve 8 can be opened, and the liquid inside the treatment tank 1 flows out from the front end of the valve 8 through the overflow pipe 7, facilitating the complete discharge of the liquid.

[0021] The working principle of an organic waste gas treatment device with biological fillers provided by the utility model is as follows: During use, connect the external organic waste gas pipe to the air inlet cavity at the lower side of the front surface of the mixing seat 9, and connect the upper air inlet cavity to the external air pipeline. Adjust the control switch group 15, and the blower 4 sucks air from the mixing seat 9. Air and organic waste gas enter the interior of the blower 4 through the two air inlet cavities, and then are output to the interior of the annular air pipe 5, and then are dispersed and flow into the interior of the treatment tank 1 through the aeration disc 6. The organic waste gas and air pass through the lower support mesh plate 1 and enter the interior of the gaps of the biological filler layer 3. Microorganisms growing on the surface of the biological filler layer 3 decompose the organic matter in the waste gas into inorganic substances, and then the gas continues to flow upward through the upper support mesh plate 1, passes through the support mesh plate 2 and the activated carbon layer 20 upward and is discharged to the outside. The activated carbon layer 20 adsorbs the organic matter in the waste gas, so as to achieve the purpose of purifying the waste gas. And during use, according to the growth requirements of microorganisms and the concentration of organic waste gas, the sizes of the air flow channels of the two can be adjusted. When adjusting, rotate the handwheel 14, the handwheel 14 drives the lead screw 13 to rotate, and the lead screw 13 drives the baffle 10 to move downward through the support seat 12 and the sliding column 11. The lower end of the baffle 10 gradually covers the lower air inlet cavity, so as to reduce the intake of organic waste gas and increase the intake of air, which can provide more oxygen for microorganisms and dilute at the same time, facilitating the high-quality treatment of high-concentration organic waste gas. And during use, connect the liquid suction end of the nutrient solution pump 16 to the nutrient solution. The nutrient solution pump 16 pumps the nutrient solution into the interior of the annular water pipe 17, and then sprays it out atomized through the atomizing nozzle 18, and then passes through the upper support mesh plate 1 and flows to the surface of the biological filler layer 3 to provide nutrients for the growth of microorganisms. The excess nutrient solution passes through the upper and lower support mesh plates 1 and enters the interior of the treatment tank 1. As the nutrient solution accumulates, the liquid level of the nutrient solution is higher than the overflow pipe 7, and the nutrient solution is discharged to the outside through the overflow pipe 7. Furthermore, the aeration disc 6 will be immersed in the nutrient solution. The nutrient solution wets the organic waste gas and air, carries nutrients to facilitate the growth of microorganisms and the treatment of organic matter. When cleaning is required, the valve 8 can be opened, and the liquid inside the treatment tank 1 flows out from the front end of the valve 8 through the overflow pipe 7, facilitating the complete discharge of the liquid.

[0022] It should be noted that the blower 4 and the nutrient solution pump 16 disclosed in the above embodiments can be freely configured according to the actual application scenarios. The blower 4 can be a blower with the model HRB-210-D1, and the nutrient solution pump 16 can be a high-pressure diaphragm pump with the model DP-125. The control switch group 15 is provided with switch buttons corresponding to the blower 4 and the nutrient solution pump 16 one by one for controlling their switching operations.
