Description

Technical Field

[0001] The invention relates to the technical field of odor treatment devices, and in particular to an odor treatment device and method for a sewage station. Background Art

[0002] In the field of environmental engineering, malodorous gases are one of the common problems faced in the water treatment process, especially in sewage treatment plants, industrial wastewater treatment facilities and other places. These malodorous gases mainly come from various complex organic and inorganic chemical reactions, and they often contain sulfides, nitrides, oxygen-containing organic matter and other harmful compounds. This type of odor not only has a serious impact on the surrounding environment, but long-term exposure can also have adverse effects on human health, such as respiratory diseases, nausea, etc. At the same time, volatile organic compounds (VOCs) and components such as hydrogen sulfide and methyl mercaptan in these gases will react secondary with other substances in the atmosphere to form more toxic or irritating products, exacerbating the problem of air pollution.

[0003] In the past few decades of research, a variety of treatment technologies have been developed for odorous gases generated during sewage treatment, including biological filtration, activated carbon adsorption, chemical oxidation, and photocatalytic oxidation. However, these technologies still have many limitations in practical applications:

[0004] (1) High operating costs: Although many advanced odor treatment technologies (such as high-efficiency chemical oxidation systems) have the advantages of good effects and thorough purification, their equipment and operating costs are relatively high. Especially in large-scale sewage treatment plants, the construction and maintenance costs of such systems significantly increase the overall expenditure of the project, limiting their widespread application. Second, the treatment speed is slow: When faced with high-concentration odor, the existing treatment system has a long reaction time and the treatment efficiency is difficult to meet the requirements of industrial production and environmental protection. For example, the biological filter requires a long reaction time to degrade organic pollutants, while the chemical adsorption system has an insufficient reaction rate to large-flow, high-concentration odorous gases and cannot quickly and thoroughly treat the odorous substances.

[0005] (2) Incomplete removal of impurities: Traditional odor treatment equipment mostly uses a single treatment method (such as physical adsorption or chemical reaction), which can only partially remove pollutants in odorous gases during the treatment process, especially particulate matter or toxic organic matter. In these systems, fine particles and volatile organic compounds in odor are difficult to remove in one go, resulting in the quality of the treated gas still not meeting environmental protection standards, low treatment efficiency, and even the need for secondary treatment to remove residual impurities, resulting in additional time and cost waste.

[0006] (3) Complex equipment maintenance: Most of the current odor treatment equipment requires frequent maintenance, especially the activated carbon adsorption device. As the adsorption material becomes saturated, the activated carbon must be replaced or regenerated regularly, otherwise the adsorption efficiency will drop rapidly, affecting the overall treatment effect. In addition, the biofilter is easily affected by changes in the external environment (such as temperature, humidity, etc.), resulting in large fluctuations in its biodegradation efficiency and high difficulty in operation and management.

[0007] (4) Insufficient environmental adaptability: Many existing odor treatment systems show obvious lack of adaptability when facing different pollution sources and changing gas components. For example, the odor components in the sewage treatment process are variable, and some systems can only treat specific types of gases, but are not effective for complex odorous gases (such as hydrogen sulfide and ammonia) with multiple harmful components, and cannot meet the comprehensive pollutant control needs.

[0008] Therefore, although the existing technology provides a variety of odor treatment methods, it still faces many bottlenecks in actual operation, including high cost, low efficiency, incomplete impurity removal and other problems, making it difficult to achieve an efficient, economical and comprehensive treatment solution. Therefore, the field of sewage treatment urgently needs a technology that can efficiently, quickly, low-cost and comprehensively remove harmful components in odor. Summary of the invention

[0009] The purpose of the present invention is to provide a sewage station odor treatment device to solve the problems raised in the above-mentioned background technology.

[0012] Preferably, a mounting groove is provided on the impurity removal box, a rubber ring is installed on the inner wall of the mounting groove, an activated carbon adsorption plate is sleeved on the rubber ring, and the bottom side of the activated carbon adsorption plate is movably mounted on the inner wall of the mounting groove.

[0013] Preferably, the spray mechanism includes a liquid storage tank, which is installed on the deodorizing tank. A liquid pump is installed on the liquid storage tank, and a connecting pipe is installed on the liquid pump. The connecting pipe passes through the top inner wall of the deodorizing tank and is installed with a spray assembly, which is installed in the deodorizing tank.

[0014] Preferably, the stirring mechanism comprises a driving shaft, which is rotatably mounted on the deodorizing box, and a plurality of stirring rods are equidistantly mounted on the driving shaft in an annular pattern, and the plurality of stirring rods equidistantly mounted in an annular pattern are all rotatably mounted in the deodorizing box.

[0015] Preferably, a support plate is installed on the deodorizing box, a motor is installed on the support plate, and the motor is installed on one end of the driving shaft.

[0016] Preferably, the impurity removal mechanism comprises a filter plate, which is movably mounted on the impurity removal box. Two guide rods are mounted on the inner walls on both sides of the impurity removal box, and scrapers are slidably mounted on the two guide rods, and the scrapers are in contact with the filter plate.

[0017] Preferably, a rotating shaft is rotatably mounted on the inner wall of the impurity removal box, and a plurality of fan blades are equidistantly mounted in a ring on the rotating shaft, and the plurality of fan blades equidistantly mounted in a ring are all compatible with the vacuum pump.

[0018] Preferably, an adapter plate is mounted on one of the blades, a transmission plate is mounted on the scraper, and the adapter plate is in contact with the transmission plate.

[0019] Preferably, a spring is sleeved on the guide rod, one end of the spring is mounted on the bottom inner wall of the debris removal box, and the other end of the spring is mounted on the scraper.

[0020] Preferably, the dust accumulation mechanism includes a limiting groove, the debris removal box is provided with a limiting groove, a dust collection drawer is slidably mounted on the inner wall of the limiting groove, the dust collection drawer is adapted to the scraper, a fixing shaft is mounted on the debris removal box, a locking rod is rotatably mounted on the fixing shaft, and the locking rod is in contact with the outer surface of the dust collection drawer.

[0021] The present invention also includes a method for treating odor in a sewage station, the method comprising the following steps:

[0022] S1. Odor extraction: Start the vacuum pump installed on the impurity removal box, and effectively collect the odor and harmful gases in the air around the sewage station through the connected odor hood and pump them into the impurity removal box. The vacuum pump provides sufficient suction to ensure that the odor is quickly guided into the treatment system to prevent the odor from spreading to the surrounding environment.

[0023] S2. Preliminary filtration: After the odor enters the impurity removal box, it first passes through the filter plate installed inside to filter the larger particles and impurities in the gas. At this time, the scraper installed on the guide rod is in close contact with the filter plate. Under the push of the airflow, the scraper automatically moves with the flow of gas, scraping off the impurities adhering to the surface of the filter plate, effectively preventing the filter plate from being blocked.

[0024] S3. Activated carbon adsorption: The filtered gas is further processed in the impurity removal box through the activated carbon adsorption plate sleeved in the installation slot. The activated carbon adsorption plate relies on its strong adsorption performance to effectively capture volatile organic compounds (VOCs) and other odorous gas components in the odor, ensuring further purification of the odor. The rubber ring fixes the activated carbon adsorption plate to ensure its stability and convenience of replacement.

[0025] S4, spraying of chemicals and decomposition of odor: Start the liquid pump installed on the liquid storage tank, transport the oxidant in the liquid storage tank to the spray assembly through the connecting pipe, and spray it evenly into the deodorization tank. The oxidant is fully in contact with the residual gas in the deodorization tank, and the odor in the gas is decomposed into harmless gas by oxidation-reduction reaction, which improves the thoroughness of odor treatment.

[0026] S5. Bubble breaking and oxidant mixing: Start the motor, drive the drive shaft to rotate through the motor, and then make the stirring rod installed on the drive shaft rotate at high speed in the deodorization box. The stirring rod breaks up the bubbles in the gas to ensure that the gas and the sprayed oxidant are fully mixed. The stirring process not only improves the reaction efficiency of gas and liquid, but also effectively accelerates the decomposition of odor in the gas.

[0027] S6. Cleaning the filter plate and collecting impurities: When the odor passes through the impurity removal box, as the fan blades rotate, the adapter plate and the transmission plate are linked to drive the scraper to move up and down along the guide rod to clean the residual impurities on the filter plate. The scraped impurities are pushed into the dust collection drawer by the scraper. The dust collection drawer cooperates with the limit groove through the sliding structure, making the impurity collection more efficient and convenient for subsequent regular cleaning and maintenance.

[0028] S7. Gas emission: The purified gas after the above treatment enters the exhaust hood through the one-way valve installed in the deodorizing box, and is finally discharged to the external environment through the gas outlet net. The exhaust hood ensures the one-way emission of the air flow to prevent the backflow of the purified gas. At the same time, the design of the gas outlet net is compatible with the exhaust hood to further block the residual particles and ensure the cleanliness of the gas emission.

[0029] S8. Equipment inspection and maintenance: Operators should regularly check the status of the rubber ring and activated carbon adsorption plate. When the adsorption effect of the activated carbon adsorption plate weakens, remove the activated carbon adsorption plate in the installation slot and replace it with a new one to ensure that the equipment continues to maintain a good odor adsorption effect. At the same time, regularly clean the dust collection drawer, unlock the locking rod by turning the retaining shaft, and pull out the dust collection drawer for cleaning to avoid impurities accumulating and affecting the operation of the equipment.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Comprehensive multi-level treatment to achieve efficient odor purification: The present invention forms a multi-level odor treatment system by organically combining physical filtration, activated carbon adsorption, chemical oxidation and stirring enhancement. Compared with the single physical or chemical treatment method in the prior art, the present invention significantly improves the treatment speed, purification effect and comprehensiveness of pollutant removal.

[0032] Specifically, the initial filtration of the filter plate can quickly remove larger particles and impurities in the odor, avoid clogging the subsequent treatment module, and ensure the continuous and efficient operation of the equipment. The activated carbon adsorption plate is used to further remove volatile organic compounds (VOCs) in the odor, significantly improving the removal efficiency of harmful components in the odorous gas. The spray mechanism decomposes the residual harmful gas components by spraying chemical oxidants to ensure the thoroughness of odor treatment. Combined with the stirring mechanism to break up the bubbles, the gas and liquid are fully mixed and reacted, which accelerates the decomposition of odor and improves the efficiency of oxidation treatment.

[0033] 2. Improve treatment efficiency and reduce operating costs: In the prior art, efficient odor treatment usually requires expensive equipment and high operating costs. The present invention reduces the overall operating costs through reasonable structural design. The combined use of the vacuum pump and the filter plate achieves fast and efficient odor extraction and filtration, reducing the gas treatment time.

[0034] Specifically, the design of activated carbon adsorption plate and rubber ring simplifies the installation and replacement of adsorption materials, prolongs the service life of the equipment, and reduces the frequency of maintenance. The linkage design of the chemical spray system and the stirring mechanism sprays the oxidant directly into the gas through the spray assembly and quickly decomposes the odor components. The high-speed stirring of the stirring rod ensures the efficient mixing reaction of the oxidant and the odor, avoids unnecessary waste of reagents, and saves reagent costs.

[0035] 3. Automatic impurity cleaning, convenient equipment maintenance: Traditional equipment requires frequent cleaning and maintenance, especially the filter is easily clogged, resulting in reduced equipment processing efficiency. The present invention significantly improves the self-cleaning ability of the equipment and reduces maintenance workload through the automatic impurity cleaning function.

[0036] Specifically, through the linkage design of the scraper and the guide rod, the scraper is driven up and down by the airflow to automatically scrape off the residual impurities on the filter plate, effectively avoiding the accumulation of impurities and blockage problems.

[0037] The combined design of the dust drawer and the limit slot makes the collection of impurities more efficient. The operator only needs to pull out the dust drawer for cleaning regularly, without the need to frequently disassemble and clean the inside of the equipment, thus simplifying maintenance work.

[0038] 4. Comprehensive and thorough odor purification, strong adaptability

[0039] The invention is suitable for treating various odor components, and has a better treatment effect on odor containing complex organic and inorganic pollutants.

[0040] Specifically, by efficiently removing volatile organic compounds (VOCs) through activated carbon adsorption plates, the problem of low removal rate of organic pollutants by traditional treatment equipment is solved. The oxidant spray system and the stirring mechanism are used in combination to treat a variety of odor components, including hydrogen sulfide, methyl mercaptan, etc., and decompose them into harmless gases through oxidation reactions. In addition, the treatment steps in the present invention can be flexibly adjusted according to the concentration, composition and environmental conditions of the odor in the sewage station, and have strong adaptability, ensuring that efficient purification effects can be maintained in different application environments.

[0041] 5. Modular design, easy to expand and apply

[0042] The present invention adopts a modular design concept, so that each functional module of the equipment (such as filtration module, adsorption module, oxidation module) works independently and can be easily disassembled and replaced. Compared with the overall integrated design of traditional equipment, modular design has the following advantages.

[0043] When the equipment needs to be expanded or replaced, it does not need to be dismantled as a whole, but only the modules need to be replaced, which greatly improves the maintainability and service life of the equipment. The independence of each module ensures the flexibility of the system, and users can adjust the system according to actual needs to meet different odor treatment needs.

[0044] 6. Efficient spray reaction, enhanced gas-liquid contact

[0045] The innovative point of the coordination between the spray mechanism and the stirring mechanism of the present invention is to use the stirring rod to disperse the bubbles, thereby enhancing the contact area and reaction speed between the gas and the liquid oxidant. This design effectively overcomes the problem of insufficient gas-liquid contact in traditional equipment.

[0046] Specifically, the gas and the oxidant spray are in contact at the same time, and the stirring effect is used to make the oxidant quickly and evenly distributed in the gas, thereby improving the reaction efficiency. This gas-liquid enhanced mixing mode can not only accelerate the decomposition of odor, but also reduce the amount of reagents used, achieving fast and efficient odor removal, while reducing the consumption of reagents and operating costs.

[0047] 7. Airflow control during the whole process to prevent secondary pollution

[0048] The one-way valve and exhaust hood design of the present invention ensure the one-way flow of the gas flow, avoid the backflow of the treated gas, and prevent secondary pollution.

[0049] After the gas enters the exhaust hood, a one-way valve is used to control the direction of the airflow to ensure that the treated purified gas can be safely discharged into the atmosphere, avoiding the risk of secondary pollution caused by the backflow of untreated gas. The design of the air outlet network further filters the residual particulate matter to ensure that the cleanliness of the exhaust gas meets environmental standards and meets the requirements of air quality around the sewage station.

[0063] In order to facilitate the deodorization of the gas exploded on the liquid surface in the deodorizing tank 1, a spray mechanism is arranged, including a liquid storage tank 3, the liquid storage tank 3 is installed on the deodorizing tank 1, a liquid extraction pump 31 is installed on the liquid storage tank 3, a connecting pipe 32 is installed on the liquid extraction pump 31, the connecting pipe 32 passes through the top inner wall of the deodorizing tank 1 and is installed with a spray assembly 33, the spray assembly 33 is installed in the deodorizing tank 1, when some bubbles are not dispersed and exploded on the liquid surface of the liquid in the deodorizing tank 1, the switch on the liquid extraction pump 31 is started, and the liquid extraction pump 31 is used to extract the oxidant in the liquid storage tank 3 and discharge it into the connecting pipe 32, and then it is sprayed onto the liquid surface in the deodorizing tank 1 through the spray assembly 33 on the connecting pipe 32, so that the gas exploded on the liquid surface in the deodorizing tank 1 can be oxidized to remove the odor.

[0064] In order to facilitate the rapid dispersion of the bubbles discharged from the exhaust hood 25 so that they can fully react with the oxidant in the deodorizing box 1, a stirring mechanism is arranged, including a driving shaft 4, which is rotatably mounted on the deodorizing box 1, and a plurality of stirring rods 41 are equidistantly mounted in a circle on the driving shaft 4, and the plurality of stirring rods 41 equidistantly mounted in a circle are all rotatably mounted in the deodorizing box 1, a supporting plate 43 is mounted on the deodorizing box 1, and a motor 42 is mounted on the supporting plate 43, and the motor 42 is mounted on one end of the driving shaft 4, and the driving shaft 4 is driven by the motor 42 to rotate, and the driving shaft 4 drives the stirring rod 41 to rotate in the deodorizing box 1, so that the bubbles discharged from the exhaust hood 25 can be quickly dispersed, so that they can fully react with the liquid medicine in the deodorizing box 1.

[0065] The method for treating odor in a sewage station using the device described in this embodiment comprises the following steps:

[0066] S1. Odor extraction: Start the vacuum pump 21 installed on the impurity removal box 2, and effectively collect the odor and harmful gases in the air around the sewage station through the connected odor hood 22 and pump them into the impurity removal box 2. The vacuum pump 21 provides sufficient suction to ensure that the odor is quickly guided into the treatment system to prevent the odor from spreading to the surrounding environment.

[0067] S2. Preliminary filtration: After the odor enters the impurity removal box 2, it first passes through the filter plate 5 installed inside to perform preliminary filtration on larger particles and impurities in the gas. At this time, the scraper 51 slidably mounted on the guide rod 52 is in close contact with the filter plate 5. Under the push of the airflow, the scraper 51 automatically moves with the flow of the gas, scraping off the impurities adhering to the surface of the filter plate 5, effectively preventing the filter plate from being blocked.

[0068] S3, activated carbon adsorption: The filtered gas is further processed in the impurity removal box 2 through the activated carbon adsorption plate 27 sleeved in the mounting groove 28. The activated carbon adsorption plate 27 relies on its strong adsorption performance to effectively capture volatile organic compounds VOCs and other malodorous gas components in the odor, ensuring further purification of the odor. The rubber ring 29 fixes the activated carbon adsorption plate 27 to ensure its stability and convenience of replacement.

[0069] S4, spraying of reagents and decomposition of odor: Start the liquid pump 31 installed on the liquid storage tank 3, transport the oxidant in the liquid storage tank 3 to the spray assembly 33 through the connecting pipe 32, and spray it evenly into the deodorizing tank 1. The oxidant is fully in contact with the residual gas in the deodorizing tank 1, and the odor in the gas is decomposed into harmless gas by oxidation-reduction reaction, thereby improving the thoroughness of odor treatment.

[0070] S5, breaking up the bubbles and mixing with the oxidant: start the motor 42, drive the drive shaft 4 to rotate through the motor 42, and then make the stirring rod 41 installed on the drive shaft 4 rotate at a high speed in the deodorizing box 1. The stirring rod 41 breaks up the bubbles in the gas to ensure that the gas and the sprayed oxidant are fully mixed. The stirring process not only improves the reaction efficiency of the gas and the liquid, but also effectively accelerates the decomposition of the odor in the gas.

[0071] S6, filter plate cleaning and impurity collection: When the odor passes through the impurity removal box 2, as the fan blade 54 rotates, the adapter plate 55 and the transmission plate 56 are linked to drive the scraper 51 to move up and down along the guide rod 52 to clean the residual impurities on the filter plate 5. The scraped impurities are pushed into the dust collection drawer 61 by the scraper 51. The dust collection drawer 61 cooperates with the limit groove 6 through the sliding structure, making the impurity collection more efficient and convenient for subsequent regular cleaning and maintenance.

[0072] S7, gas discharge: The purified gas after the above treatment enters the exhaust hood 25 through the one-way valve 24 installed in the deodorizing box 1, and is finally discharged to the external environment through the gas outlet net 26. The exhaust hood 25 ensures the one-way discharge of the air flow to prevent the backflow of the purified gas. At the same time, the design of the gas outlet net 26 is compatible with the exhaust hood 25, further blocking the residual particles and ensuring the cleanliness of the gas discharge.

[0073] S8, Equipment inspection and maintenance: The operator regularly checks the status of the rubber ring 29 and the activated carbon adsorption plate 27. When the adsorption effect of the activated carbon adsorption plate 27 weakens, the activated carbon adsorption plate 27 in the installation slot 28 is removed and replaced with a new adsorption plate to ensure that the equipment continues to maintain a good odor adsorption effect. At the same time, the dust collection drawer 61 is cleaned regularly, and the locking rod 63 is unlocked by rotating the retaining shaft 62, and the dust collection drawer 61 is pulled out for cleaning to prevent impurities from accumulating and affecting the operation of the equipment.

[0074] Embodiment 2: On the basis of embodiment 1, in order to facilitate the removal of dust and impurities in the odor, a cleaning mechanism is arranged, including a filter plate 5, the filter plate 5 is movably mounted on the cleaning box 2, two guide rods 52 are mounted on the inner walls of both sides of the cleaning box 2, scrapers 51 are slidably mounted on the two guide rods 52, the scrapers 51 are in contact with the filter plate 5, a rotating shaft 53 is rotatably mounted on the inner wall of the cleaning box 2, a plurality of fan blades 54 are equidistantly mounted on the rotating shaft 53, the plurality of fan blades 54 are equidistantly mounted in an annular manner, and all of them are adapted to the vacuum pump 21, one of which An adapter plate 55 is installed on the fan blade 54, a transmission plate 56 is installed on the scraper 51, the adapter plate 55 is in contact with the transmission plate 56, a spring 57 is sleeved on the guide rod 52, one end of the spring 57 is installed on the bottom inner wall of the dust removal box 2, and the other end of the spring 57 is installed on the scraper 51.

The gas drawn into the dust collecting box 2 by the vacuum pump 21 will be filtered by the filter plate 5. At the same time, the gas blown into the dust collecting box 2 drives the fan blade 54 on the rotating shaft 53 to rotate. The fan blade 54 drives the adapter plate 55 to rotate. The adapter plate 55 drives the transmission plate 56 to move downward. The transmission plate 56 drives the scraper 51 on the guide rod 52 to move downward on the filter plate 5. The scraper 51 drives the spring 57 to squeeze. When the adapter plate 55 is separated from the transmission plate 56, the spring 57 is used to The restoring force of the spring 57 drives the scraper 51 to move upward on the filter plate 5, so that the residual impurities on the fan blades 54 can be easily removed to prevent the filter holes on the fan blades 54 from being blocked by excessive impurities. At the same time, the impurities cleaned from the filter plate 5 by the scraper 51 will fall into the dust drawer 61. After the dust and impurities in the dust drawer 61 are fully collected, the locking rod 63 on the retaining shaft 62 can be rotated to release the restraint on the dust drawer 61, so that the dust drawer 61 can be easily pulled out for cleaning, which is convenient for subsequent use. The remaining features are the same as those in Example 1.

[0075] The working principle is as follows: when purifying the odor from the sewage station, first start the switch on the vacuum pump 21, use the vacuum pump 21 to draw the odor from the sewage station into the impurity removal box 2 through the odor hood 22, and filter it through the filter plate 5 on the impurity removal box 2.

When the adapter plate 55 is separated from the transmission plate 56, the restoring force of the spring 57 is used to drive the scraper 51 to move upward on the filter plate 5, so that the residual impurities on the fan blades 54 can be easily removed to prevent the filter holes on the fan blades 54 from being blocked by excessive impurities. At the same time, the impurities cleaned by the scraper 51 on the filter plate 5 will fall into the dust drawer 61. After the dust and impurities in the dust drawer 61 are fully collected, the locking rod 63 on the retaining shaft 62 can be rotated to release the restraint on the dust drawer 61, so that the dust drawer 61 can be easily pulled out for cleaning, which is convenient for subsequent In use, the filtered odor is adsorbed by the activated carbon adsorption plate 27 on the impurity removal box 2, so that part of the odor can be removed conveniently. The adsorbed odor is discharged into the oxidant in the deodorization box 1 through the exhaust hood 25 on the air inlet pipe 23 to react, so that the remaining odor can be removed. At the same time, the switch of the motor 42 on the support plate 43 is started, and the motor 42 is used to drive the drive shaft 4 to rotate, and the drive shaft 4 drives the stirring rod 41 to rotate in the deodorization box 1, so that the bubbles discharged from the exhaust hood 25 can be quickly dispersed, so that it can fully react with the air in the deodorization box 1. The liquid medicine reacts fully. When some bubbles are not dispersed and explode on the liquid surface in the deodorizing tank 1, the switch on the liquid pump 31 is started, and the oxidant in the liquid storage tank 3 is extracted and discharged into the connecting pipe 32 by the liquid pump 31, and then sprayed onto the liquid surface in the deodorizing tank 1 through the spray assembly 33 on the connecting pipe 32, so that the gas exploded on the liquid surface in the deodorizing tank 1 can be oxidized to remove the odor. After the above steps, not only the odor in the air can be removed quickly and conveniently, but also the impurities in the air can be removed to avoid pollution to the surrounding environment.

10. A method for treating odor in a sewage station, characterized in that: The method comprises the following steps: S1. Odor extraction: Start the vacuum pump (21) installed on the impurity removal box (2), and effectively collect the odor and harmful gases in the air around the sewage station through the connected odor hood (22) and draw them into the impurity removal box (2). The vacuum pump (21) provides sufficient suction to ensure that the odor is quickly guided into the treatment system to prevent the odor from spreading to the surrounding environment. S2, preliminary filtration: After the odor enters the impurity removal box (2), it first passes through the filter plate (5) installed inside to perform preliminary filtration on larger particles and impurities in the gas. At this time, the scraper (51) slidably mounted on the guide rod (52) is in close contact with the filter plate (5). Under the push of the airflow, the scraper (51) automatically moves with the flow of the gas, scraping off the impurities adhering to the surface of the filter plate (5), effectively preventing the filter plate from being blocked. S3, activated carbon adsorption: The filtered gas is further processed in the impurity removal box (2) through an activated carbon adsorption plate (27) sleeved in the mounting groove (28). The activated carbon adsorption plate (27) relies on its strong adsorption performance to effectively capture volatile organic compounds (VOCs) and other malodorous gas components in the odor, ensuring further purification of the odor. The rubber ring (29) fixes the activated carbon adsorption plate (27) to ensure its stability and convenience of replacement. S4, spraying of reagents and decomposition of odors: Start the liquid pump (31) installed on the liquid storage tank (3), transport the oxidant in the liquid storage tank (3) to the spray assembly (33) through the connecting pipe (32), and spray it evenly into the deodorizing tank (1). The oxidant fully contacts the residual gas in the deodorizing tank (1), and decomposes the odor in the gas into harmless gas by oxidation-reduction reaction, thereby improving the thoroughness of odor treatment. S5, breaking up the bubbles and mixing with the oxidant: starting the motor (42), driving the drive shaft (4) to rotate through the motor (42), thereby causing the stirring rod (41) installed on the drive shaft (4) to rotate at a high speed in the deodorizing box (1). The stirring rod (41) breaks up the bubbles in the gas to ensure that the gas and the sprayed oxidant are fully mixed. The stirring process not only improves the reaction efficiency of the gas and the liquid, but also effectively accelerates the decomposition of the odor in the gas. S6, filter plate cleaning and impurity collection: When the odor passes through the impurity removal box (2), as the fan blade (54) rotates, the adapter plate (55) and the transmission plate (56) are linked to drive the scraper (51) to move up and down along the guide rod (52) to clean the residual impurities on the filter plate (5). The scraped impurities are pushed into the dust collection drawer (61) by the scraper (51). The dust collection drawer (61) cooperates with the limit groove (6) through the sliding structure, making the impurity collection more efficient and facilitating the subsequent regular cleaning and maintenance. S7, gas discharge: The purified gas after the above treatment enters the exhaust hood (25) through the one-way valve (24) installed in the deodorizing box (1), and is finally discharged to the external environment through the gas outlet net (26). The exhaust hood (25) ensures the one-way discharge of the air flow to prevent the backflow of the purified gas. At the same time, the design of the gas outlet net (26) is compatible with the exhaust hood (25), further blocking the residual particulate matter and ensuring the cleanliness of the gas discharge. S8. Equipment inspection and maintenance: The operator shall regularly check the status of the rubber ring (29) and the activated carbon adsorption plate (27). When the adsorption effect of the activated carbon adsorption plate (27) weakens, the activated carbon adsorption plate (27) in the installation slot (28) shall be removed and replaced with a new adsorption plate to ensure that the equipment continues to maintain a good odor adsorption effect. At the same time, the dust collection drawer (61) shall be cleaned regularly, and the locking rod (63) shall be unlocked by rotating the retaining shaft (62), and the dust collection drawer (61) shall be pulled out for cleaning to avoid the accumulation of impurities affecting the operation of the equipment.
