Description

Technical Field

[0001] The present invention relates to the field of biological purification of waste gas, and more specifically, to a biological soil deodorization device. Background Art

[0002] Biological soil deodorization is an eco-friendly technology that utilizes natural soil and microorganisms. Microorganisms in the soil (such as bacteria and fungi) decompose the organic matter (such as hydrogen sulfide and ammonia) in the odor gas as "food", and convert it into harmless substances such as carbon dioxide and water, eliminating the malodorous gas through decomposition, adsorption, and conversion.

[0003] Biological soil deodorization filter materials are usually divided into three categories: organic filter materials, inorganic filter materials, and mixed filter materials. Currently, the most commonly used filter materials are the filter materials composed of a combination of mixed filter materials and inorganic filter materials. For example, the prior art (a Chinese invention patent application with the publication number CN117101393A) discloses a pH self-regulating type waste gas biological soil deodorization filter material and its deodorization device. Its deodorization filter material uses a biochar compounded soil filter material (organic) and an inorganic filter material. Although it can achieve the deodorization effect, the organic filter material initially has a relatively high porosity, which provides good conditions for gas transmission and microbial attachment. However, the organic filter material is prone to a decrease in porosity due to microbial reproduction. The biofilm not only covers the surface of the filter material particles but also extends into the particle gaps. With the secretion of microbial metabolites (EPS: extracellular polymeric substances), the original open pores become sticky and narrow, and the air flow resistance rises sharply. In severe cases, the microorganisms will die due to oxygen deficiency and the deodorization will fail. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a biological soil deodorization device.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0010] Further, two staggered turning assemblies are respectively connected to the two groups of bed turning parts. The staggered turning assembly includes a plurality of third gears rotatably connected inside the two rotating discs, internal gear rings fixedly connected in the two movable grooves one and meshing with the plurality of third gears, a plurality of second rods located between the two rotating discs, and a plurality of branch rods two fixedly connected to the outer surfaces of the plurality of second rods. The two ends of the second rod are respectively fixedly connected to the third gears inside the two rotating discs.

[0011] Further, the plurality of second rods are all composed of inner rods and outer rods connected to the outside of the inner rods, and the plurality of branch rods two are fixedly connected to the outside of the outer rods. The two ends of the inner rod are respectively fixedly connected to the adjacent two third gears.

[0012] Further, the outer rod is movably sleeved outside the inner rod, and a targeted loosening assembly is connected inside the inner rod. The targeted loosening assembly includes a movable groove two opened inside the inner rod, a movable rod movably connected inside the inner rod, a slider slidably connected to the inner wall of the movable groove two and fixedly connected to the outer surface of the movable rod, a spring located inside the movable groove two, and a ball rotatably connected to one end of the movable rod. One end of the slider penetrates through the movable groove two and is fixedly connected to the inner wall of the outer rod. A groove is opened on the inner wall of the movable groove one, and a plurality of inclined surface top blocks are integrally formed on the inner wall of the groove. One end of the movable rod sequentially penetrates through the inner rod, the third gear, the rotating disc and enters the groove, and the ball at one end of the movable rod contacts the inner wall of the groove.

[0013] Further, two columns of dead - angle loosening parts are longitudinally arranged inside the housing. The dead - angle loosening part includes three rod bodies three rotatably connected to the inner wall of the housing, two sleeves and multiple branch rod bodies three respectively fixed on the outer surfaces of the three rod bodies three, and multiple inclined support rods fixed on the outer surfaces of the sleeves. A plurality of driving sources three are fixedly connected to one side of the housing, and the output shafts of the plurality of driving sources three penetrate the housing and are respectively fixedly connected to one ends of the multiple rod bodies three.

[0014] Further, the support assembly includes multiple air supply pipes fixedly connected to the lower end of the housing, multiple hollow pipes fixedly connected to the bottom wall of the housing and communicating with the air supply pipes, a support plate fixedly connected to the inner wall of the housing and fixed to the outer surfaces of the multiple hollow pipes, multiple drainage grooves opened inside the support plate, a filter plate fixedly connected to the upper end of the support plate and sleeved outside the multiple hollow pipes, and multiple openings respectively opened on the outer surfaces of the upper ends of the multiple hollow pipes.

[0015] Further, a plurality of spray pipes are fixedly connected to the upper end of the housing.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this solution, a material internal turning assembly is provided. The driving source one drives the concave seat to perform a translational movement in the mixed filter material, which can push and loosen the filter material, effectively filling in local dense or low - porosity areas. During the translational movement of the concave seat and the driven translational movement of the rod body one, the transmission part drives the rod body one and the branch rod one to rotate in the mixed filter material. The rotation of the rod body one combined with the cutting and prying actions of the branch rod one can further open small pores, improving the air permeability of the mixed filter material. Moreover, the branch rod one generates a gentle shear on the biofilm attached to the surface of the filter material, prompting the aging or overly thick biofilm to fall off. After the fresh biofilm is exposed, the microbial proliferation is more sufficient, maintaining high activity, extending the service life of the filter material, eliminating blockages caused by microbial activities or mud accumulation, dynamically reshaping the channels through turning and stirring in the mixed filter material layer, redistributing gas and nutrient solution to the entire bed cross - section, improving the overall mass transfer efficiency, and at the same time, the stirring action disperses the possible dry areas or water - rich areas in the bed layer, making the pressure difference more uniform.

[0017] (2) This solution is provided with an interleaved turning component. While the rotating disk drives the first rod to rotate, it can also drive multiple second rods to rotate. Since the third gear in the rotating disk meshes with the internal gear disk, when the multiple second rods rotate, they can also generate self-rotation. The high-frequency local shear generated by the multiple second rods rotating around the first rod in the reverse direction and superimposed on the forward rotation of the first rod forms an interleaved shear effect, which can penetrate into fine pores and pry loose agglomerated particles, improving the crushing effect on the agglomerated filter material. The forward rotation of the first rod provides large-scale pushing and breaking of agglomerations; the reverse self-rotation of the second rods provides small-scale tearing and shearing. The combination of the two greatly improves the overall looseness and air permeability of the filter material layer. The reverse shear force can also prompt the peeling off of the overly thick biofilm, preventing the collapse and blockage of pores by the aging bacterial layer.

[0018] (3) This solution is provided with a targeted loosening component. The second branch rod can not only perform shearing and self-rotation on its rotation trajectory, but also perform axial translation along with the outer rod, accurately scanning the agglomerated lumps at different positions in the bed layer, enabling the second branch rod to swing back and forth near the dead zone, locally strengthening the disturbance. Moreover, the translation function can "level" or "fill" the unevenness on the surface and inside of the filter material bed layer, avoiding the long-term existence of local depressions with accumulated liquid and raised channels.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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.

[0022] Please refer to Figures 1 to 10 , a biological soil deodorization device, including a housing 1, inorganic filter media 3 and mixed filter media 2 located inside the housing 1, two side covers 11 fixedly connected to both sides of the housing 1, a support assembly connected to the lower part inside the housing 1 for supporting the inorganic filter media 3 and for exhausting air, and an in-bed agitation assembly 4 connected inside the housing 1; The in-bed agitation assembly 4 includes a concave seat 42 located inside the housing 1, two sets of bed agitation parts 5 connected to the inner side wall of the concave seat 42, and two sets of transmission parts 44 connected inside the concave seat 42 for driving the bed agitation parts 5 to rotate. The two ends of the concave seat 42 extend out of the housing 1 and are slidably connected to the upper end of the housing 1. A drive part for driving the concave seat 42 to move is connected between the two side covers 11; The bed agitation part 5 includes two first movable grooves 55 symmetrically opened on the inner side wall of the concave seat 42, two rotating discs 52 respectively rotatably connected in the two first movable grooves 55, a first rod 53 with two ends fixedly connected to the two rotating discs 52 respectively, and a plurality of first branch rods 54 fixedly connected to the outer surface of the first rod 53.

[0023] Both sides of the concave seat 42 are provided with drag-reducing inclined surfaces 421 (to reduce the drag of the concave seat 42 when translating in the mixed filter material 2). The driving part includes a guide rod with both ends fixedly connected to the two side covers 11 respectively, a lead screw 41 rotatably connected between the two side covers 11, and a first driving source 43 fixedly connected to one side of one of the side covers 11. The output shaft of the first driving source 43 penetrates through the side cover 11 and is fixedly connected to one end of the lead screw 41. One end of the concave seat 42 is screwed outside the lead screw 41 and the other end is movably sleeved outside the guide rod.

[0024] The transmission part 44 includes a first synchronous pulley 442 and a second synchronous pulley 443 rotatably connected inside the concave seat 42, a synchronous belt 444 connecting the first synchronous pulley 442 and the second synchronous pulley 443, a first gear 445 rotatably connected inside the concave seat 42, and a second gear 51 meshing with the first gear 445. The first gear 445 is fixedly connected to one side of the second synchronous pulley 443. The second gear 51 is fixedly connected to one side of the rotating disc 52. Two synchronous second driving sources 441 are fixedly connected to both sides of the concave seat 42 respectively. The output shafts of the two second driving sources 441 penetrate into the concave seat 42 and are respectively fixedly connected to the two first synchronous pulleys 442.

[0025] The support assembly includes multiple air supply pipes 15 fixedly connected to the lower end of the housing 1, multiple hollow pipes 13 fixedly connected to the bottom wall of the housing 1 and communicating with the air supply pipes 15, a support plate 10 fixedly connected to the inner wall of the housing 1 and fixedly connected to the outer surfaces of the multiple hollow pipes 13, multiple drainage grooves 101 opened inside the support plate 10, a filter plate 9 fixedly connected to the upper end of the support plate 10 and sleeved outside the multiple hollow pipes 13, multiple openings 14 respectively opened on the outer surfaces of the upper ends of the multiple hollow pipes 13. The inorganic filter material 3 is located above the filter plate 9. The mixed filter material 2 is located above the inorganic filter material 3. A water storage cavity 12 is formed between the inner bottom of the housing 1 and the support plate 10. Multiple drain ports 16 communicating with the water storage cavity 12 are opened at the bottom of the housing 1. Multiple spray pipes 17 are fixedly connected to the upper end of the housing 1.

[0026] By adopting the above technical solution, the malodorous gas is conveyed into the air supply pipe 15, enters the hollow pipe 13 from the air supply pipe 15, and is discharged from a plurality of openings 14 on the hollow pipe 13. One end of the hollow pipe 13 provided with the plurality of openings 14 is located inside the inorganic filter material 3. After the gas is discharged from the openings 14, it enters the mixed filter material 2 from the pores of the inorganic filter material 3, and is discharged from the housing 1 after being purified by the biological treatment of the mixed filter material 2. The nutrient solution is regularly sprayed into the mixed filter material 2 through the spray pipe 17 to provide nutrients for the microorganisms in the mixed filter material 2. The liquid flows to the support plate 10 after passing through the mixed filter material 2, the inorganic filter material 3 and the filter plate 9, and flows into the water storage cavity 12 from the drainage groove 101 inside the support plate 10, and finally is discharged from the drainage port 16. The two driving sources two 441 are regularly controlled to work synchronously (multiple driving sources in this application are all composed of power structures such as motors and reducers, and controlling the two driving sources two 441 to work synchronously also belongs to a mature technology in the prior art. For example, the errors of the two motors can be adjusted in real time through the PID algorithm, PLC combined with a synchronous driver or other methods, which will not be elaborated here). When the two driving sources two 441 work, they drive the two synchronous pulleys one 442 to rotate. The rotation of the two synchronous pulleys one 442 drives the two synchronous pulleys two 443 to rotate through the synchronous belt 444. The rotation of the two synchronous pulleys two 443 drives the gear one 445 to rotate. The rotation of the gear one 445 drives the gear two 51 to rotate. When the gear two 51 rotates, it drives the rotating disk 52, the rod body one 53 and the branch rod one 54 to rotate, so that the rod body one 53 and the plurality of branch rods one 54 can stir in the mixed filter material 2. While the rod body one 53 rotates, the driving source one 43 is controlled to work to drive the lead screw 41 to rotate. The rotation of the lead screw 41 drives the concave seat 42 to move. When the concave seat 42 moves, it can drive the rod body one 53 and the plurality of branch rods one 54 to translate in the mixed filter material 2. The rotation of the rod body one 53 combined with the cutting and prying actions of the branch rod one 54 can further open the fine pores, improve the air permeability of the mixed filter material 2, and the branch rod one 54 produces a gentle shear on the biofilm attached to the surface of the filter material, prompting the aging or overly thick biofilm to fall off. After the fresh biofilm is exposed, the microorganisms proliferate more fully, maintaining high activity, extending the service life of the filter material, eliminating blockages caused by microbial activities or mud accumulation. By flipping and stirring the mixed filter material 2 layer, the channels can be dynamically reshaped, enabling the gas and nutrient solution to be redistributed to the entire layer cross-section, improving the overall mass transfer efficiency. At the same time, the stirring action breaks up the possible dry areas or water-rich areas in the bed layer, making the pressure difference more uniform.

[0027] Such as Figure 6 and Figure 7As shown in the figure, two staggered turning components 6 are respectively connected to the two groups of bed turning parts 5, and the staggered turning component 6 includes a plurality of third gears 61 rotatably connected inside the two rotating discs 52, an internal gear ring 64 fixedly connected in the two first moving grooves 55 and meshing with the plurality of third gears 61, a plurality of second rods 62 located between the two rotating discs 52, and a plurality of branch rods 63 fixedly connected to the outer surfaces of the plurality of second rods 62, and the two ends of the second rod 62 are respectively fixedly connected to the third gears 61 inside the two rotating discs 52.

[0028] The plurality of second rods 62 are all composed of an inner rod 621 and an outer rod 622 connected to the outside of the inner rod 621, and the plurality of branch rods 63 are fixedly connected to the outside of the outer rod 622, and the two ends of the inner rod 621 are respectively fixedly connected to the adjacent two third gears 61.

[0029] By adopting the above technical solution, when the second gear 51 drives the rotating disc 52 to rotate, the third gear 61 inside the rotating disc 52 can rotate along with the rotating disc 52. Since the third gear 61 meshes with the internal gear ring 64, when the rotating disc 52 rotates, the third gear 61 can rotate self - rotatably inside the rotating disc 52. When the third gear 61 rotates self - rotatably, it can drive the second rod 62 and the plurality of branch rods 63 to rotate self - rotatably, and the rotating directions of the second rod 62 and the plurality of branch rods 63 are opposite to the rotating direction of the first rod 53. The reverse self - rotation of the plurality of second rods 62 around the first rod 53 is superimposed on the forward rotation of the first rod 53 to generate high - frequency local shear, forming an interleaved shear effect, which can penetrate into fine pores and pry agglomerated particles, improving the crushing effect on the agglomerated filter material. The forward rotation of the first rod 53 provides large - scale extrusion and breaks up agglomerates; the reverse self - rotation of the second rod 62 provides small - scale tearing and shearing. The combination of the two greatly improves the overall looseness and air permeability of the filter material layer. The reverse shear force can also promote the peeling of the overly thick biofilm and prevent the collapse and blockage of pores by the aging bacterial layer.

[0030] As Figures 6 - 9 shown, the outer rod 622 is movably sleeved outside the inner rod 621, and a targeted loosening component 7 is connected inside the inner rod 621. The targeted loosening component 7 includes a second moving groove 71 opened inside the inner rod 621, a moving rod 73 movably connected inside the inner rod 621, a slider 74 slidably connected to the inner wall of the second moving groove 71 and fixedly connected to the outer surface of the moving rod 73, a spring 75 located inside the second moving groove 71, and a ball 72 rotatably connected to one end of the moving rod 73. One end of the slider 74 passes through the second moving groove 71 and is fixedly connected to the inner wall of the outer rod 622. A groove 76 is opened on the inner wall of the first moving groove 55, and a plurality of inclined surface top blocks 77 are integrally formed on the inner wall of the groove 76. One end of the moving rod 73 sequentially passes through the inner rod 621, the third gear 61, the rotating disc 52 and enters the groove 76, and the ball 72 at one end of the moving rod 73 is in contact with the inner wall of the groove 76.

[0031] By adopting the above technical solution, when the rotating disk 52 drives the third gear 61 to rotate, the ball 72 can move in the groove 76. When the ball 72 contacts the inclined surface top block 77, the inclined surface top block 77 can apply a force to the ball 72, causing the ball 72 and the movable rod 73 to move in the direction of the spring 75. The movable rod 73 moves in the inner rod body 621 in the direction of the spring 75 and compresses the spring 75. When the movable rod 73 moves, it drives the outer rod body 622 to move outside the inner rod body 621 through the slider 74. After the ball 72 separates from the inclined surface top block 77, the spring 75 pushes the movable rod 73 to move back to its original position. To sum up, the rotation of the rotating disk 52 can not only drive the outer rod body 622 and the second branch rod 63 to rotate, but also enable the outer rod body 622 and the second branch rod 63 to perform axial translation, accurately scan the agglomerated lumps at different positions in the bed layer, enable the second branch rod 63 to swing back and forth near the dead zone, locally strengthen the disturbance, and the translation function can "level" or "fill" the unevenness on the surface and inside of the filter media bed layer, avoiding the long-term existence of local depressions with accumulated liquid and raised channels.

[0032] As Figure 3 shown, two columns of dead zone loosening parts 8 are also longitudinally arranged inside the housing 1, and the dead zone loosening part 8 includes three third rods 81 rotatably connected to the inner wall of the housing 1, two sleeves 84 and a plurality of third branch rods 83 respectively fixed on the outer surfaces of the three third rods 81, and a plurality of inclined support rods 85 fixed on the outer surface of the sleeve 84. A plurality of third driving sources 82 are also fixed on one side of the housing 1, and the output shafts of the plurality of third driving sources 82 penetrate the housing 1 and are respectively fixed to one ends of the plurality of third rods 81.

[0033] By adopting the above technical solution, the operation of the third driving source 82 can drive the third rod 81 to rotate, and the rotation of the third rod 81 drives the plurality of third branch rods 83 and the plurality of inclined support rods 85 to rotate. By rotating the plurality of third branch rods 83 and the plurality of inclined support rods 85, the filter media at the edge of the inner wall of the housing 1 can be agitated, avoiding the occurrence of dead zones in the filter media at the edge of the inner wall of the housing 1 and making the filter media looser more evenly.

[0034] Usage method: The malodorous gas is transported into the air supply pipe 15, enters the hollow pipe 13 from the air supply pipe 15, and is discharged from multiple openings 14 on the hollow pipe 13. One end of the hollow pipe 13 provided with multiple openings 14 is located inside the inorganic filter material 3. After the gas is discharged from the openings 14, it enters the mixed filter material 2 from the pores of the inorganic filter material 3, and is discharged from the housing 1 after being purified by the biological treatment of the mixed filter material 2. The nutrient solution is regularly sprayed into the mixed filter material 2 through the spray pipe 17 to provide nutrients for the microorganisms in the mixed filter material 2. The liquid flows to the support plate 10 after passing through the mixed filter material 2, the inorganic filter material 3 and the filter plate 9, and flows into the water storage cavity 12 from the drainage groove 101 inside the support plate 10, and is finally discharged from the drainage port 16. The driving part can drive the concave seat 42 to translate in the mixed filter material 2, and the transmission part 44 can drive the bed turnover part 5 to work. When the driving rod body one 53 and the branch rod one 54 rotate in the mixed filter material 2, when the gear two 51 drives the rotating disk 52 to rotate, the gear three 61 inside the rotating disk 52 can rotate along with the rotating disk 52. When the rotating disk 52 rotates, the gear three 61 can rotate self - rotatably inside the rotating disk 52, and when the gear three 61 rotates self - rotatably, it can drive the rod body two 62 and multiple branch rods two 63 to rotate self - rotatably, and the rotating directions of the rod body two 62 and multiple branch rods two 63 are opposite to the rotating direction of the rod body one 53. The reverse self - rotation of multiple rod bodies two 62 around the rod body one 53 is superimposed on the forward rotation of the rod body one 53 to generate high - frequency local shear.

[0035] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.
