Description

Technical Field

[0001] The present invention relates to the technical field of biological purification trickling filtration, and in particular to a biological purification device and a use method thereof. Background Art

[0002] The quantity and types of low-concentration organic waste gases emitted from various production processes are increasing day by day. These low-concentration organic waste gases contain a variety of volatile organic compounds (VOCs), which seriously pollute the air and endanger human health and the ecological environment.

[0003] Biotrickling filtration is an environmentally friendly technology that uses microorganisms to degrade organic waste gas. In this method, organic waste gas passes through a tower reactor filled with microbial membranes, which are able to convert harmful organic matter into harmless water and carbon dioxide. Since this process mainly relies on the metabolic activity of microorganisms, the operating conditions are relatively mild, energy consumption is low, and no secondary pollution is generated.

[0004] During the use of the biological dripping tower, microorganisms are reproduced by continuously spraying nutrient solution. The continuous reproduction of internal microorganisms will gradually lead to blockage inside the filler, affecting the purification of exhaust gas. The traditional treatment method is to repeatedly flush the filler with high-pressure water or remove the filler for cleaning. Repeated cleaning of the filler with high-pressure water will cause a waste of water resources. At the same time, removing the filler for cleaning will consume a lot of time, affecting the efficiency of exhaust gas purification. Summary of the invention

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a method for using a biological purification device. Through the method for using the biological purification device, it is possible to scrape off excess biofilm and filter the recycled nutrient solution.

[0035] The water storage tray 202 inside the rotating scraping mechanism 200 cooperates with the rotating assembly 204 to drive the rotating rod 201 to rotate, so that the removing assembly 203 can scrape off the excess biofilm on the surface of the hollow filler 107; The nutrient solution discharged from the water storage tray 202 is filtered through the activated carbon filter cartridge 301 inside the collection and filtering mechanism 300, and the impurities inside are collected at the same time.

[0036] The water storage tray 202 on the surface of the rotating rod 201 inside the rotating scraping mechanism 200 cooperates with the rotating assembly 204 to drive the rotating rod 201 to rotate, so that the rotating rod 201 can drive the hollow filler 107 to rotate through the water outlet pipe 105, so that the hollow filler 107 can cooperate with the removing assembly 203 to remove the excess biofilm on the surface after rotating; The nutrient solution accumulated on the water storage tray 202 is discharged into the activated carbon filter cartridge 301 through the drainage component 302 inside the collection and filtering mechanism 300, so that the activated carbon filter cartridge 301 can filter the nutrient solution accumulated in the water storage tray 202 and collect and adsorb impurities inside the nutrient solution.

[0037] Reference Figures 1 to 4 and Figures 6-8 , which is a second embodiment of the present invention, provides a rotating scraping mechanism 200, through which the excess biofilm can be scraped off to prevent the biofilm from clogging the hollow filler 107.

[0038] The rotary scraping mechanism 200 includes a rotary rod 201, which is fixedly connected to the bottom of the water outlet pipe 105. A water storage tray 202 is sleeved on the top of the surface of the rotary rod 201. A rejection component 203 is provided on the top of the surface of the hollow filler 107. A rotating component 204 is provided on the surface of the rotary rod 201. A limiting component 205 is fixedly connected to the surface of the water storage tray 202. A mounting seat 206 is fixedly connected to the bottom of the surface of the rotary rod 201. A torsion spring 207 is fixedly connected to the bottom of the inner wall of the drip filter tower body 101.

[0039] The rejection assembly 203 includes a first spiral groove 203a, which is opened at the top of the hollow filler 107, and a second spiral groove 203b is opened at the bottom of the hollow filler 107. Both sides of the inner wall of the trickling filter body 101 are fixedly connected with a sliding frame 203c, and both sides of the inside of the first spiral groove 203a and both sides of the inside of the second spiral groove 203b are movably connected with a rejection block 203d, and the rejection block 203d is movably connected to the inside of the sliding frame 203c.

[0040] The rotating component 204 includes a spiral transmission groove 204a, which is opened on the surface of the rotating rod 201. The surface of the rotating rod 201 is provided with a transmission sleeve 204b. Both sides of the transmission sleeve 204b are fixedly connected with guide pins 204c. The guide pins 204c are movably connected to the spiral transmission groove 204a. The bottom of the transmission sleeve 204b is fixedly connected to the top of the water storage tray 202.

[0041] The limiting assembly 205 includes a limiting block 205a, which is fixedly connected to the surface of the water storage tray 202. A plurality of limiting blocks 205a are provided and are distributed in a circular shape with equal distances. The inner wall of the inner wall of the drip filter body 101 is provided with a limiting groove 205b. A plurality of limiting grooves 205b are provided and are distributed in a circular shape with equal distances. The limiting block 205a is movably connected to the limiting groove 205b.

[0042] Specifically, as the amount of nutrient solution accumulated in the water storage tray 202 increases, the overall weight will also increase. At this time, the water storage tray 202 will move downward and drive the limit block 205a to move inside the limit groove 205b, so that the cooperation between the limit block 205a and the limit groove 205b can keep the water storage tray 202 moving up and down stably. In the process of the water storage tray 202 moving downward, it will drive the transmission sleeve 204b to move downward on the surface of the rotating rod 201, so that the transmission sleeve 204b can move downward inside the spiral transmission groove 204a by driving the guide pin 204c, so that the spiral transmission groove 204a can drive the rotating rod 201 to rotate, and the rotating rod 201 can drive the water outlet pipe 105 to rotate.

[0043] When the rotating rod 201 drives the hollow filler 107 to rotate through the water outlet pipe 105, the removal block 203d inside the sliding frame 203c can remove the biofilm inside the first spiral groove 203a and the second spiral groove 203b, so that the biofilm on the surface of the hollow filler 107 can reproduce to the position after the biofilm is removed, thereby preventing the biofilm from growing inside the hollow filler 107 and clogging the hollow filler 107.

[0044] Furthermore, when excess nutrient solution flows downward, it will be continuously collected by the water storage tray 202. As the weight of the nutrient solution collected by the water storage tray 202 increases, the limit block 205a will be driven to move downward inside the limit groove 205b. In the process of the water storage tray 202 moving downward, the transmission sleeve 204b can be driven to move downward, so that after the transmission sleeve 204b moves downward, it can drive the guide pin 204c to move downward inside the spiral transmission groove 204a, so that the coordinated use of the guide pin 204c and the spiral transmission groove 204a can drive the rotating rod 201 to rotate, so that after the rotating rod 201 rotates, it can drive the water outlet pipe 105 to rotate.

[0045] When the outlet pipe 105 rotates, the hollow filler 107 is driven to rotate, and when the hollow filler 107 rotates, the first spiral groove 203a and the second spiral groove 203b are driven to rotate. When the hollow filler 107 rotates, the rejection block 203d inside the first spiral groove 203a and the second spiral groove 203b will follow the path of the first spiral groove 203a and the second spiral groove 203b and move outward inside the sliding frame 203c. In the process of the rejection block 203d moving outward inside the sliding frame 203c, the biofilm inside the first spiral groove 203a and the second spiral groove 203b will be removed, so that the removed biofilm flows downward along with the flowing nutrient solution, and the biofilm on the hollow filler 107 will reproduce toward the position where the biofilm is removed, thereby preventing the biofilm from growing inside the hollow filler 107 and clogging the hollow filler 107.

[0046] It should be noted that the path lengths of the first spiral groove 203a and the second spiral groove 203b are different. The path length of the first spiral groove 203a is longer than that of the second spiral groove 203b, so that the removal block 203d removes a larger area of ​​biofilm on the top when removing the biofilm on the surface of the hollow filler 107, because the nutrient solution will first contact the top of the hollow filler 107, making the biofilm reproduction rate on the top of the hollow filler 107 greater than the reproduction rate of the biofilm on the bottom.

[0047] Reference Figures 1 to 5 , which is the third embodiment of the present invention, provides a collecting and filtering mechanism 300, through which the nutrient solution is filtered and the internal impurities are collected.

[0048] The collecting and filtering mechanism 300 includes an activated carbon filter cartridge 301, which is fixedly mounted on the top of the mounting seat 206. A plurality of activated carbon filter cartridges 301 are arranged and are distributed equidistantly in a ring shape. A drainage assembly 302 is provided on the top of the water storage tray 202. The interior of the activated carbon filter cartridge 301 is movably connected to a scraping assembly 303, and the top of the surface of the activated carbon filter cartridge 301 is movably connected to an extension trigger assembly 304.

[0049] The drainage assembly 302 includes a drainage groove 302a, which is opened at the top of the inner wall of the water storage tray 202. There are several drainage grooves 302a and they are distributed in a circular shape with equal distances. The drainage grooves 302a correspond to the activated carbon filter cartridge 301. A fixed shaft 302b is fixedly connected to the inner side of the inner wall of the drainage groove 302a, and a sealing plate 302c is movably connected to the surface of the fixed shaft 302b. The sealing plate 302c is movably connected to the drainage groove 302a, and a top rod 302d is fixedly connected to the bottom of the inner wall of the activated carbon filter cartridge 301, and the top of the top rod 302d is movably connected to the sealing plate 302c.

[0050] The scraping assembly 303 includes a scraping ring 303a, a spring 303b is fixedly connected to the bottom of the inner wall of the activated carbon filter cartridge 301, a connecting frame 303c is fixedly installed inside the scraping ring 303a, the bottom of the connecting frame 303c is fixedly connected to the top of the spring 303b, and a trigger rod 303d is fixedly connected to the outer side of the top of the connecting frame 303c, and the trigger rod 303d is movably connected to the bottom of the water storage tray 202.

[0051] The extension trigger assembly 304 includes an extension ring 304a, which is movably connected to the top of the activated carbon filter cartridge 301, and the inner wall of the extension ring 304a is fixedly connected to a fixed block 304b, and the bottom of the fixed block 304b is fixedly connected to a waterproof trigger switch 304c, and the top of the surface of the drip filter tower body 101 is fixedly connected to a warning light 304d, and the waterproof trigger switch 304c is electrically connected to the warning light 304d.

[0052] Specifically, when the top rod 302d pushes the sealing plate 302c upward, the nutrient solution on the water storage tray 202 will enter the activated carbon filter cartridge 301 through the drainage groove 302a, so that the activated carbon filter cartridge 301 can adsorb and filter the impurities in the nutrient solution.

[0053] At the same time, the descent of the water storage tray 202 will drive the trigger rod 303d to move downward, so that after the trigger rod 303d moves downward, it can drive the scraper ring 303a to move downward through the connecting frame 303c. When the water storage tray 202 moves upward, the spring 303b at the bottom of the connecting frame 303c will drive the scraper ring 303a to move upward through its own elastic force, so that the scraper ring 303a can scrape impurities on the inner wall of the activated carbon filter cartridge 301 during the up and down movement.

[0054] When too much impurities accumulate on the scraper ring 303a, it will contact the waterproof trigger switch 304c on the fixed block 304b, so that the waterproof trigger switch 304c can start the prompt light 304d. After the prompt light 304d is on, it can remind the operator to clean the impurities inside the activated carbon filter cartridge 301. At the same time, the extension ring 304a can effectively prevent the impurities on the scraper ring 303a from being too much and higher than the activated carbon filter cartridge 301 and falling off.

[0055] Furthermore, during the rotation of the rotating rod 201, the mounting seat 206 will be driven to rotate, so that the mounting seat 206 can drive the activated carbon filter cartridge 301 to rotate, so that after the activated carbon filter cartridge 301 rotates, the range of contact between itself and the nutrient solution can be increased, so that the activated carbon filter cartridge 301 can better adsorb other substances inside the nutrient solution, and at the same time, the torsion spring 207 will be driven to rotate through the mounting seat 206 to generate torque.

[0056] When the water storage tray 202 moves downward a certain distance, the activated carbon filter cartridge 301 will rotate to the bottom of the sealing plate 302c. As the water storage tray 202 continues to move downward, the push rod 302d inside the activated carbon filter cartridge 301 will lift up the sealing plate 302c inside the drainage groove 302a, so that the sealing plate 302c will rotate along the fixed shaft 302b, thereby releasing the seal of the drainage groove 302a, allowing the nutrient solution accumulated on the water storage tray 202 to flow downward through the drainage groove 302a.

[0057] At this time, the activated carbon filter cartridge 301 is located at the bottom of the drainage trough 302a, and the nutrient solution flowing downward will continuously enter the activated carbon filter cartridge 301, so that the hydraulic pressure entering the activated carbon filter cartridge 301 can be filtered by the activated carbon filter cartridge 301, and the impurities in the nutrient solution entering the activated carbon filter cartridge 301 are collected, preventing the nutrient solution carrying impurities from being sucked into the circulating water pump 104 again.

[0058] At the same time, the water storage tray 202 will push the trigger rod 303d downward when it starts to move downward, so that the trigger rod 303d can drive the scraper ring 303a to move downward through the connecting frame 303c when it moves downward. When the connecting frame 303c drives the scraper ring 303a to move downward, the spring 303b will be squeezed. When the scraper ring 303a moves, it will scrape away impurities and excess biofilm on the inner wall of the activated carbon filter cartridge 301 to avoid clogging the activated carbon filter cartridge 301.

[0059] When the nutrient solution on the water storage tray 202 is discharged through the drainage groove 302a, the overall weight of the water storage tray 202 is reduced, so that the torsion spring 207 can drive the rotating rod 201 to rotate in the opposite direction through the torque, so that the rotating rod 201 can drive the guide pin 204c inside the transmission sleeve 204b to move upward through the spiral transmission groove 204a, so that the guide pin 204c drives the water storage tray 202 to move upward through the transmission sleeve 204b. When the water storage tray 202 moves upward, the spring 303b at the bottom of the connecting frame 303c will drive the scraper ring 303a to reset through its own elastic force, so that the scraper ring 303a can scrape the impurities for the second time, and when the scraper ring 303a moves upward and scrapes away too many impurities, it will contact the waterproof trigger switch 304c on the fixed block 304b, so that the waterproof trigger switch 304c can control the switch of the prompt light 304d to prompt the operator to clean the impurities, and the fixed block 304b will drive the extension ring 304a to move upward to increase the height of the activated carbon filter cartridge 301 to prevent impurities from falling above the activated carbon filter cartridge 301.

[0060] The remaining structure is the same as that of Example 2.

[0061] Reference Figures 1 to 8, which is the fourth embodiment of the present invention, is different from the third embodiment in that: a biological purification device.

[0062] When in use, a certain amount of nutrient solution is first injected into the trickling filter body 101 so that the nutrient solution reaches an amount that can be circulated after the circulating water pump 104 is started. Then the circulating water pump 104 is started, so that the circulating water pump 104 injects the nutrient solution into the outlet pipe 105 through the rotary joint 110 inside the bracket 109, so that the nutrient solution inside the outlet pipe 105 can flow out through the outlet hole 108 and cover the hollow filler 107, so that a biofilm grows on the surface of the hollow filler 107, and excess nutrient solution will continue to flow downward.

[0063] The waste gas is then injected into the inside of the trickling filter body 101 through the air inlet pipe 102 . When the waste gas passes through the hollow filler 107 , it will be purified by the surface biofilm and discharged through the air outlet pipe 103 .

[0064] During the downward flow of excess nutrient solution, it will be continuously collected by the water storage tray 202. As the weight of the nutrient solution collected by the water storage tray 202 increases, the limit block 205a will be driven to move downward inside the limit groove 205b. During the downward movement of the water storage tray 202, the transmission sleeve 204b can be driven to move downward. After the transmission sleeve 204b moves downward, it can drive the guide pin 204c to move downward inside the spiral transmission groove 204a. The coordinated use of the guide pin 204c and the spiral transmission groove 204a can drive the rotating rod 201 to rotate, and after the rotating rod 201 rotates, it can drive the water outlet pipe 105 to rotate.

[0065] When the outlet pipe 105 rotates, the hollow filler 107 is driven to rotate, and when the hollow filler 107 rotates, the first spiral groove 203a and the second spiral groove 203b are driven to rotate. When the hollow filler 107 rotates, the rejection block 203d inside the first spiral groove 203a and the second spiral groove 203b will follow the path of the first spiral groove 203a and the second spiral groove 203b and move outward inside the sliding frame 203c. In the process of the rejection block 203d moving outward inside the sliding frame 203c, the biofilm inside the first spiral groove 203a and the second spiral groove 203b will be removed, so that the removed biofilm flows downward along with the flowing nutrient solution, and the biofilm on the hollow filler 107 will reproduce toward the position where the biofilm is removed, thereby preventing the biofilm from growing inside the hollow filler 107 and clogging the hollow filler 107.

[0066] At the same time, during the rotation of the rotating rod 201, the mounting seat 206 will be driven to rotate, so that the mounting seat 206 can drive the activated carbon filter cartridge 301 to rotate, so that after the activated carbon filter cartridge 301 rotates, it can increase the range of contact between itself and the nutrient solution, so that the activated carbon filter cartridge 301 can better absorb other substances inside the nutrient solution, and at the same time, the torsion spring 207 will be driven to rotate through the mounting seat 206 to generate torque.

[0067] When the water storage tray 202 moves downward a certain distance, the activated carbon filter cartridge 301 will rotate to the bottom of the sealing plate 302c. As the water storage tray 202 continues to move downward, the push rod 302d inside the activated carbon filter cartridge 301 will lift up the sealing plate 302c inside the drainage groove 302a, so that the sealing plate 302c will rotate along the fixed shaft 302b, thereby releasing the seal of the drainage groove 302a, allowing the nutrient solution accumulated on the water storage tray 202 to flow downward through the drainage groove 302a.

[0068] At this time, the activated carbon filter cartridge 301 is located at the bottom of the drainage trough 302a, and the nutrient solution flowing downward will continuously enter the activated carbon filter cartridge 301, so that the hydraulic pressure entering the activated carbon filter cartridge 301 can be filtered by the activated carbon filter cartridge 301, and the impurities in the nutrient solution entering the activated carbon filter cartridge 301 are collected, preventing the nutrient solution carrying impurities from being sucked into the circulating water pump 104 again.

[0069] At the same time, the water storage tray 202 will push the trigger rod 303d downward when it starts to move downward, so that the trigger rod 303d can drive the scraper ring 303a to move downward through the connecting frame 303c when it moves downward. When the connecting frame 303c drives the scraper ring 303a to move downward, the spring 303b will be squeezed. When the scraper ring 303a moves, it will scrape away impurities and excess biofilm on the inner wall of the activated carbon filter cartridge 301 to avoid clogging the activated carbon filter cartridge 301.

[0070] When the nutrient solution on the water storage tray 202 is discharged through the drainage groove 302a, the overall weight of the water storage tray 202 will be reduced, so that the torsion spring 207 can drive the rotating rod 201 to rotate in the opposite direction through the torque. When the rotating rod 201 rotates in the opposite direction, it will drive the guide pin 204c inside the transmission sleeve 204b to move upward through the spiral transmission groove 204a, so that the guide pin 204c drives the water storage tray 202 to move upward through the transmission sleeve 204b.

[0071] After the rotating rod 201 rotates in the opposite direction, it can drive the water outlet pipe 105 to rotate again, so that when the water outlet pipe 105 rotates, it will drive the hollow filler 107 to rotate, and when the hollow filler 107 rotates, it will drive the first spiral groove 203a and the second spiral groove 203b to rotate. When the hollow filler 107 rotates, the rejection block 203d inside the first spiral groove 203a and the second spiral groove 203b will follow the path of the first spiral groove 203a and the second spiral groove 203b and move inward inside the sliding frame 203c. In the process of the rejection block 203d moving inward inside the sliding frame 203c, the biofilm inside the first spiral groove 203a and the second spiral groove 203b will be rejected again, and the biofilm will reproduce toward the position where the biofilm is rejected, thereby preventing the biofilm from growing inside the hollow filler 107 and clogging the hollow filler 107.

[0072] When the water storage tray 202 moves upward, the spring 303b at the bottom of the connecting frame 303c will drive the scraper ring 303a to reset through its own elastic force, so that the scraper ring 303a can scrape the impurities for the second time, and when the scraper ring 303a moves upward and scrapes away too many impurities, it will contact the waterproof trigger switch 304c on the fixed block 304b, so that the waterproof trigger switch 304c can control the switch of the prompt light 304d to prompt the operator to clean the impurities, and the fixed block 304b will drive the extension ring 304a to move upward to increase the height of the activated carbon filter cartridge 301 to prevent impurities from falling above the activated carbon filter cartridge 301.

[0073] When the exhaust gas is injected into the inside of the trickling filter body 101 through the air intake pipe 102, the spoiler B will be driven to rotate, causing the rotating ring A to rotate inside the limiting ring C, so that the rotating spoiler B can continuously disperse the exhaust gas entering the inside of the trickling filter body 101, so that the dispersed exhaust gas can contact the hollow filler 107 more evenly, thereby increasing the purification efficiency of the biofilm on the hollow filler 107 for the exhaust gas.

[0074] In summary, the removal component 203 inside the rotating scraping mechanism 200 is used to remove excess biofilm to prevent the biofilm from growing inside the hollow filler 107 and clogging the hollow filler 107. At the same time, the activated carbon filter cartridge 301 inside the collecting and filtering mechanism 300 can filter the nutrient solution.
