Description

Technical Field

[0001] This invention belongs to the field of odor treatment technology, specifically a composite biological deodorization device and method for treating large volumes of high-concentration odorous gases. Background Technology

[0002] Composite biological deodorization equipment is an environmental protection device that integrates physical, chemical, and biological principles, specifically designed to treat large-scale, high-concentration industrial or municipal odorous gases. This type of equipment typically employs a combined "pretreatment + biological treatment" process. The pretreatment section (such as a chemical scrubbing tower or water scrubbing tower) first removes some soluble substances and dust through spray absorption and regulates temperature and humidity. The biological treatment section is the core; the odorous gas is introduced into a biofilter / trickling filter tower filled with organic or inorganic packing material, the surface of which is covered with a acclimated microbial film. As the odorous components pass through, they are adsorbed and absorbed by the biofilm, serving as energy or substrate for microbial metabolism, and ultimately decomposed into harmless products such as carbon dioxide, water, sulfates, and nitrates.

[0003] Existing composite biological deodorization equipment for treating large volumes of high-concentration odorous gases tends to crystallize and accumulate bacteria on the inner wall of the spray mechanism after the liquid containing different bacterial groups is used to treat the odor. Due to the difficulty in disassembling the spray mechanism and the limited internal space, it causes great inconvenience for personnel to clean the crystals and bacteria. If the crystals and bacteria are not cleaned, problems such as system blockage, uneven flow, accelerated corrosion, and shortened lifespan will occur.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figure 1-5 and Figure 7 As shown in the embodiment of the present invention, a composite biological deodorization device for treating large volumes of high-concentration odorous gas includes a treatment cylinder 1. An air inlet pipe 41 is fixedly connected to the outside of the treatment cylinder 1, a liquid inlet pipe 2 is fixedly connected to the top of the treatment cylinder 1, a plurality of liquid injection pipes 3 are fixedly connected to the outside of the liquid inlet pipe 2, and an air outlet pipe 28 is fixedly connected to the surface of the treatment cylinder 1. Switch valves are provided on the air inlet pipe 41, the liquid inlet pipe 2, the liquid injection pipes 3 and the air outlet pipe 28. A connecting rod 4 is fixedly connected to the inner wall of the liquid inlet pipe 2. A pair of symmetrically distributed elastic ropes 5 are fixedly connected to the bottom of the connecting rod 4. The bottom ends of the pair of elastic ropes 5 are fixedly connected to the same scraper ring 6. A nozzle 7 is movably inserted into the bottom end of the liquid inlet pipe 2. A pair of symmetrically distributed winding ropes 15 are fixedly connected between the nozzle 7 and the scraper ring 6. A pair of symmetrically distributed side wall grooves 8 are opened on the inner wall of the liquid inlet pipe 2. An electric push rod 9 is fixedly connected to the inner wall of the side wall groove 8. A limit block 10 is fixedly connected to the telescopic end of the electric push rod 9. A pair of limit grooves 11 that are adapted to the limit block 10 are opened on the outer side of the nozzle 7. A motor 12 is fixedly connected to the inner wall of the processing cylinder 1. A crossbar 13 is fixedly connected to the output end of the motor 12. The same winding rope 14 is fixedly connected between the crossbar 13 and the nozzle 7. A pull-out door 17 is fixedly connected to the side of the processing cylinder 1 by fasteners, specifically bolts. An observation plate 16 is fixedly connected inside the pull-out door 17. The observation plate 16 is made of transparent material. An electric push rod 18 is fixedly connected to the side of the observation plate 16. A receiving cylinder 19 is fixedly connected to the telescopic end of the electric push rod 18. The receiving cylinder 19 has a water filter hole 20. After the receiving cylinder 19 has finished collecting crystals and bacteria, the pull-out door 17 needs to be removed from the processing cylinder 1, and then the receiving cylinder 19 needs to be removed from the processing cylinder 1. Finally, the crystals and bacteria in the receiving cylinder 19 can be cleaned. A collection cylinder 21 is fixedly connected to the bottom of the processing cylinder 1. A collection box 22 is movably inserted inside the collection cylinder 21.

[0023] In the existing technology, the existing composite biological deodorization equipment for treating large volumes of high-concentration odorous gas uses liquid containing different bacterial groups to treat the odorous gas. However, after the liquid treats the odorous gas, it is easy for crystals and bacterial groups to form on the inner wall of the spray mechanism. Since the spray mechanism is difficult to disassemble and the internal space is insufficient, it causes great inconvenience to personnel when cleaning the crystals and bacterial groups. If the crystals and bacterial groups are not cleaned, problems such as system blockage, uneven flow, accelerated corrosion and shortened life will occur. The present invention is used in the following steps: Step 1: Connect the external high-pressure water injection device to the inlet pipe 2, then inject water into the inlet pipe 2, and according to the type of odorous water, inject liquid containing different bacterial groups into the inlet pipe 2 through the injection pipe 3 to mix with the water. Finally, the mixed liquid will be sprayed downward from the nozzle 7. Then, the odorous gas is injected into the treatment cylinder 1 through the air inlet pipe 41. The mixed liquid of water and liquid containing different bacterial groups is used to degrade and reduce dust in the odorous gas. Step 2: After treating the odor, when cleaning the crystals and bacteria attached to the inner wall of the liquid inlet pipe 2, the electric push rod 9 needs to be activated to pull the limiting block 10 back into the limiting groove 11 until the limiting block 10 is separated from the limiting groove 11, so as to release the limiting effect of the limiting block 10 on the nozzle 7. Start motor 12, so that its output end drives the crossbar 13 to rotate and wind up the winding rope 14. Under the pull of the winding rope 14, the nozzle 7 and all its mechanisms will move down. At the same time, the elastic rope 5 will be stretched, so that the scraper ring 6 moves down inside the liquid inlet pipe 2 to scrape off the crystals and bacteria attached to the inner wall of the liquid inlet pipe 2. Step 3: Before scraping off the crystals and bacteria, the electric push rod 18 needs to be activated so that its telescopic end pushes the receiving cylinder 19 to move directly below the nozzle 7, and uses it to collect the scraped crystals and bacteria. Step 4: After pulling the scraper ring 6 to the outlet near the bottom of the liquid inlet pipe 2, the output end of motor 12 drives the crossbar 13 to reverse, and the winding rope 14 is unwound. At the same time, under the action of the elastic rope 5, the scraper ring 6 and all its mechanisms are moved upward and reset, thus completing one cleaning of the inner wall of the liquid inlet pipe 2. Finally, repeat the above steps to clean the inner wall of the liquid inlet pipe 2 multiple times. During the cleaning process, water can be injected into the liquid inlet pipe 2 to rinse the crystals and bacteria adhering to the liquid inlet pipe 2 and the scraper ring 6 and all the mechanical surfaces on the scraper ring 6. This not only optimizes the cleaning effect, but also speeds up the entry of crystals and bacteria into the receiving cylinder 19. Step 5: After the mixture of water, crystals and bacteria enters the receiving cylinder 19, the water will be removed from the filter hole 20 and temporarily stored in the collection box 22.

[0024] In summary, when using this invention, firstly, the electric push rod 9 is activated to release the limit on the nozzle 7. Then, the motor 12 is activated, and the nozzle 7 is pulled downwards via the winding rope 14. Simultaneously, the scraper ring 6, connected to it, scrapes the inner wall of the liquid inlet pipe 2 under the guidance of the elastic rope 5. Before cleaning, the receiving cylinder 19 is pushed below the nozzle 7 to collect the scraped material. After scraping is completed, the motor 12 reverses, and the elastic rope 5 pulls the scraper ring 6 back to its original position. This operation can be repeated or supplemented with water rinsing to enhance cleaning. This invention achieves online mechanical self-cleaning without... The need to disassemble the pipes greatly reduces maintenance difficulty, time, and safety risks; the cleaning process is automatic and thorough, with the scraper ring 6 completely removing the deposits on the inner wall, and the flushing can optimize the cleaning effect and accelerate the discharge of dirt; the collection and separation of dirt is achieved, and the scraped solid crystals, bacterial sludge, and liquid are effectively separated through the receiving cylinder 19 with filter holes and the collection box 22, which facilitates subsequent processing. Overall, this invention fundamentally solves the maintenance problems of scaling and biofilm growth on the inner wall of the spray mechanism, ensuring the uniformity of spraying and the long-term stable operation of the system.

[0025] like Figure 7 As shown, a filter plate 23 is movably inserted inside the collection box 22. A pair of plug-in blocks 24 are fixedly connected to the outer side of the filter plate 23. A pair of plug-in slots 25 adapted to the plug-in blocks 24 are opened on the inner wall of the collection box 22. A water outlet pipe 27 is fixedly connected to the outer side of the collection box 22. A water outlet valve is provided on the water outlet pipe 27. The wastewater entering the collection box 22 is filtered through the filter plate 23 to improve the cleanliness of the wastewater and reduce the subsequent wastewater treatment steps.

[0026] like Figure 7As shown, the filter plate 23 is equipped with a sensor and a controller inside, and a fault light 26 is fixedly connected to the outside of the collection box 22. When the water flow through the filter plate 23 is greatly reduced due to foreign objects and sludge clogging the filter plate 23, the fault light 26 will light up to remind personnel to clean the foreign objects and sludge on the filter plate 23 in time.

[0027] like Figure 5 As shown, a sealing ring 29 is fixedly connected to the inner wall of the liquid inlet pipe 2. The inner wall of the sealing ring 29 is tightly fitted to the outer side of the nozzle 7. The sealing ring 29 can improve the sealing performance at the connection between the liquid inlet pipe 2 and the nozzle 7, and prevent water leakage at the connection.

[0028] like Figure 6 As shown, circular blocks 30 are rotatably connected to the outer sides of the collection cylinder 21 via rotating shafts. A second circular block 31 is fixedly connected to the bottom of each circular block 30 via a fixing block. In the initial state, the side of the second circular block 31 abuts against the collection box 22. During use, the circular blocks 30 are rotated downwards, rotating the circular blocks 30 and all its mechanisms to... Figure 1 At the position in the middle, the circular block 31 abuts against the collection box 22 to limit the collection box 22 and make it difficult for it to move out of the collection cylinder 21.

[0029] like Figure 6 and Figure 8 As shown, the side of the second circular block 31 is coated with a magnetic coating 32, and the outer sides of the collection box 22 and the collection cylinder 21 are coated with a magnetic coating 33 that is magnetically connected to the magnetic coating 32. The circular block 30 and all its mechanisms are rotated to... Figure 1 After the magnetic coating 32 is in the middle position, it will be magnetically connected to the magnetic coating 33, thereby improving the stability of the connection between the round block 31 and the collection box 22.

[0030] like Figure 4 As shown, a pair of limiting rings 34 are fixedly connected to the crossbar 13. One end of the second winding rope 14 is located between the pair of limiting rings 34. The limiting rings 34 can ensure that the second winding rope 14 is wound up in a fixed area on the crossbar 13, so that it remains neat.

[0031] like Figure 2 and Figure 7 As shown, a sealing layer one is fixedly connected to the outer side of the collection box 22, and a sealing layer two is fixedly connected to the outer side of the pull-out door 17. The outer side of the sealing layer one is tightly fitted to the inner wall of the collection cylinder 21. The sealing layer one can improve the sealing performance at the connection between the collection cylinder 21 and the collection box 22. The outer side of the sealing layer two is tightly fitted to the inner wall of the processing cylinder 1. The sealing layer two can improve the sealing performance between the processing cylinder 1 and the pull-out door 17.

[0032] Example 2: Figure 9-10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a second motor 35 is fixedly connected to the inner bottom wall of the receiving cylinder 19, a first scraper 36 is fixedly connected to the output end of the second motor 35, a second scraper 37 is fixedly connected to a pair of sides of the first scraper 36, the side of the second scraper 37 away from the first scraper 36 abuts against the inner wall of the receiving cylinder 19, and the bottom of the first scraper 36 abuts against the inner bottom wall of the receiving cylinder 19; A pair of scrapers 37 are fixedly connected to the same ring 38. A micro air pump is installed inside the ring 38. A rubber inflation ring 39 is fixedly connected to the inner wall of the ring 38. The air outlet of the micro air pump is connected to the rubber inflation ring 39. An electric push rod 40 is fixedly connected to the inner top wall of the scraper 37, and the telescopic end of the electric push rod 40 is fixedly connected to the top of the ring 38.

[0033] The present invention is used in the following steps: Step 1: As crystals and bacteria continuously enter and accumulate in the receiving cylinder 19, motor 2 35 can be started, causing its output end to drive scraper 1 36 and scraper 2 37 to rotate together in the receiving cylinder 19. Scraper 1 36 is used to push away the crystals and bacteria accumulated on the bottom wall of the receiving cylinder 19, and scraper 2 37 is used to push away the crystals and bacteria attached to the inner side wall of the receiving cylinder 19, so that the water in the crystals and bacteria can smoothly pass through the filter water hole 20 and be removed from the receiving cylinder 19. Step 2: When separating the water from the crystals and bacteria, a micro air pump can be started to inflate the rubber air ring 39, causing it to expand and move towards the central opening to fill it, thus forming a solid circular object. Then, the electric push rod 3 40 is started, and its telescopic end pushes the circular ring 38 and the rubber air ring 39 downwards. The two of them squeeze the crystals and bacteria accumulated in the receiving cylinder 19 downwards to squeeze out the water and accelerate the separation of the two from the water.

[0034] In summary, when the scraped crystals and bacterial sludge accumulate in the receiving cylinder 19, the second motor 35 is started to drive the first scraper 36 and the second scraper 37 to rotate, scraping away the dirt accumulated at the bottom and inner wall and pushing it towards the center, promoting the rapid filtration of water from the filter holes 20. Subsequently, the micro air pump is started to inflate the rubber air ring 39, sealing the central opening to form a compaction head. Then, the electric push rod 40 is started to push the ring 38 and the rubber air ring 39 downward, mechanically squeezing the dirt for further powerful dehydration. Therefore, this invention significantly accelerates the solid-liquid separation speed and improves the dehydration efficiency through the dual action of rotational scraping and mechanical squeezing. The rotating scraper can effectively prevent dirt from hardening and accumulating at the bottom and inner wall of the receiving cylinder 19, avoiding the clogging of the filter holes 20, ensuring smooth drainage and the effective volume of the receiving cylinder 19.

This method employs the aforementioned composite biological deodorization equipment for treating large volumes of high-concentration odorous gases and includes the following steps: S1: Inject the liquid containing different bacterial groups for treating odor into the inlet pipe 2, mix it with water, and spray it into the odor to purify the odor. S2: Rewind the crossbar 13 to move the scraper ring 6 down inside the inlet pipe 2 to scrape away the crystals and bacteria on the inner wall of the inlet pipe 2; S3: Move the receiving cylinder 19 directly below the nozzle 7 and use the receiving cylinder 19 to collect the scraped crystals and bacteria.
