Description

Technical Field

[0001] The utility model relates to the technical field of odor treatment devices, in particular to an odor treatment device 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 originate from various complex organic and inorganic chemical reactions, and they often contain sulfides, nitrogen compounds, 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 and nausea. At the same time, volatile organic compounds (VOCs) and components such as hydrogen sulfide and methyl mercaptan in these gases will undergo secondary reactions with other substances in the atmosphere to form more toxic or irritating products, exacerbating the problem of air pollution.

[0003] Over the past few decades, 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 application:

[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 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 impurity removal: Traditional odor treatment equipment often uses a single treatment method (such as physical adsorption or chemical reaction), which can only partially remove pollutants in malodorous gases during the treatment process, especially particulate matter or toxic organic matter. In these systems, fine particles and volatile organic compounds in the odor are difficult to remove in one go, resulting in the treated gas quality still not meeting environmental 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: Current odor treatment equipment often requires frequent maintenance, especially activated carbon adsorption devices. As the adsorption material becomes saturated, the activated carbon must be regularly replaced or regenerated. 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 and humidity), 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 exhibit significant inadequacy in adaptability to different pollution sources and changing gas compositions. For example, the odor composition in sewage treatment varies greatly, and some systems can only treat specific types of gases. They are not very effective for complex odorous gases (such as hydrogen sulfide and ammonia) with multiple harmful components, and therefore cannot meet the needs of comprehensive pollutant control.

[0008] Therefore, while existing technologies offer a variety of odor treatment methods, they still face numerous operational bottlenecks, including high costs, low efficiency, and incomplete impurity removal, making it difficult to achieve an efficient, economical, and comprehensive treatment solution. Therefore, the wastewater treatment industry urgently needs a technology that can efficiently, quickly, and cost-effectively remove harmful components from odor. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Comprehensive multi-level treatment for efficient odor purification: This utility model organically combines physical filtration, activated carbon adsorption, chemical oxidation, and enhanced agitation to form a multi-level odor treatment system. Compared with existing technologies that rely solely on physical or chemical treatment, this utility model significantly improves treatment speed, purification effectiveness, and comprehensive pollutant removal.

[0023] Initial filtration through the filter plate quickly removes larger particles and impurities from the odor, preventing blockage in subsequent treatment modules and ensuring continued efficient operation of the equipment. The activated carbon adsorption plate further removes volatile organic compounds (VOCs) from the odor, significantly improving the removal efficiency of harmful components in malodorous gases. The spray mechanism decomposes residual harmful gas components by spraying chemical oxidants, ensuring thorough odor treatment. Combined with the stirring mechanism to break up bubbles, the gas and liquid are fully mixed and reacted, accelerating odor decomposition and improving oxidation treatment efficiency.

[0024] 2. Improve treatment efficiency and reduce operating costs: In existing technologies, efficient odor treatment typically requires expensive equipment and high operating costs. This utility model reduces overall operating costs through a rational structural design. The combination of the vacuum pump and filter plate achieves fast and efficient odor extraction and filtration, reducing gas treatment time.

[0025] The design of the activated carbon adsorption plate and rubber ring simplifies the installation and replacement of the adsorption material, extending the equipment's service life and reducing maintenance frequency. The integrated chemical spray system and stirring mechanism spray the oxidant directly into the gas through the spray assembly, rapidly decomposing odor components. Combined with the high-speed stirring of the stirring rod, this ensures an efficient mixing reaction between the oxidant and the odor, avoiding unnecessary chemical waste and saving chemical costs.

[0026] 3. Automatic impurity cleaning and convenient equipment maintenance: Traditional equipment requires frequent cleaning and maintenance, especially the filter is prone to clogging, resulting in reduced equipment processing efficiency. The utility model significantly improves the self-cleaning ability of the equipment through the automatic impurity cleaning function and reduces the maintenance workload.

[0027] 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.

[0028] The combined design of the dust collection drawer and the limit slot makes the collection of impurities more efficient. Operators only need to pull out the dust collection drawer for cleaning regularly, without the need to frequently disassemble and clean the inside of the equipment, simplifying maintenance work.

[0029] 4. Comprehensive and thorough odor purification with strong adaptability

[0030] The utility model is suitable for treating various odor components, and has a better treatment effect on odor containing complex organic and inorganic pollutants.

[0031] Specifically, by efficiently removing volatile organic compounds (VOCs) through activated carbon adsorption plates, the low removal rate of organic pollutants in traditional treatment equipment is resolved. The oxidant spray system, in conjunction with the stirring mechanism, can treat a variety of malodorous components, including hydrogen sulfide and methyl mercaptan, and decompose them into harmless gases through oxidation reactions. Furthermore, the treatment steps in this utility model can be flexibly adjusted based on the concentration, composition, and environmental conditions of the sewage station odor, demonstrating strong adaptability and ensuring efficient purification results in different application environments.

[0032] 5. Modular design, easy to expand and apply

[0033] This utility model adopts a modular design concept, allowing each functional module of the device (such as the filtration module, adsorption module, and oxidation module) to operate independently and be easily disassembled and replaced. Compared with the overall integrated design of traditional equipment, the modular design has the following advantages.

[0034] When the equipment needs to be expanded or replaced, it can be replaced by replacing specific modules without having to dismantle the entire system, greatly improving the equipment's maintainability and service life. The independence of each module ensures system flexibility, allowing users to customize the system to meet different odor treatment requirements.

[0035] 6. Efficient spray reaction, enhanced gas-liquid contact

[0036] The innovative coordination of the spray mechanism and stirring mechanism in this utility model utilizes a stirring rod to disperse bubbles, thereby increasing the contact area and reaction speed between the gas and liquid oxidant. This design effectively overcomes the problem of insufficient gas-liquid contact in traditional equipment.

[0037] Specifically, by simultaneously contacting the gas and oxidant spray, the stirring effect allows the oxidant to be quickly and evenly distributed throughout the gas, improving reaction efficiency. This enhanced gas-liquid mixing mode not only accelerates odor decomposition but also reduces the amount of reagents used, achieving rapid and efficient odor removal while reducing reagent consumption and operating costs.

[0038] 7. Airflow control during the whole process to prevent secondary pollution

[0039] The one-way valve and exhaust hood design of the utility model ensure the one-way flow of the airflow, avoid the backflow of the treated gas, and prevent secondary pollution.

[0040] After the gas enters the exhaust hood, a one-way valve controls the direction of the airflow, ensuring that the treated, purified gas can be safely discharged into the atmosphere, avoiding the risk of secondary contamination caused by the backflow of untreated gas. The exhaust screen design further filters out residual particulate matter, ensuring that the exhaust gas is clean and meets environmental standards, meeting air quality requirements around the sewage station.

[0052] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] Example 1: Please refer to Figure 1-10 The utility model provides a technical solution: a sewage station odor treatment device includes a deodorizing box 1, a deodorizing mechanism, a spraying mechanism and a stirring mechanism are installed on the deodorizing mechanism, a debris removal mechanism and a dust accumulation mechanism are installed on the deodorizing mechanism, and the debris removal mechanism and the dust accumulation mechanism are adapted to each other. The deodorizing mechanism includes a debris removal box 2, which is installed on the deodorizing box 1, an air pump 21 is installed on the upper surface of the debris removal box 2, an odor hood 22 is installed on the air pump 21, an air intake pipe 23 is installed on the bottom side of the debris removal box 2, a one-way valve 24 is installed on the inner wall of the bottom side of the deodorizing box 1, an exhaust hood 25 is installed on the one-way valve 24, the exhaust hood 25 is installed in the deodorizing box 1, and one end of the air intake pipe 23 passes through The inner wall of the bottom side of the deodorizing box 1 is installed on the one-way valve 24, and an air outlet net 26 is provided on the upper side of the deodorizing box 1, and the air outlet net 26 is adapted to the exhaust hood 25. A mounting groove 28 is provided on the deodorizing box 2, and a rubber ring 29 is installed on the inner wall of the mounting groove 28. An activated carbon adsorption plate 27 is sleeved on the rubber ring 29. The bottom side of the activated carbon adsorption plate 27 is movably installed on the inner wall of the mounting groove 28. The filtered odor is adsorbed by the activated carbon adsorption plate 27 on the deodorizing box 2, so that part of the odor can be removed conveniently. The adsorbed odor is discharged into the oxidant in the deodorizing box 1 through the exhaust hood 25 on the air inlet pipe 23 to react, so that the remaining odor can be removed.

[0054] 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, which is installed on the deodorizing tank 1, and a liquid extraction pump 31 is installed on the liquid storage tank 3, and 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 equipped with a spray assembly 33, which is installed in the deodorizing tank 1. When some bubbles are not broken up 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.

[0055] In order to facilitate the rapid breakup 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 drive shaft 4, which is rotatably mounted on the deodorizing box 1, and a plurality of stirring rods 41 are equidistantly mounted in a ring on the drive shaft 4, and the plurality of stirring rods 41 equidistantly mounted in a ring are all rotatably mounted in the deodorizing box 1, a support plate 43 is mounted on the deodorizing box 1, and a motor 42 is mounted on the support plate 43, and the motor 42 is mounted on one end of the drive shaft 4, and the drive shaft 4 is driven to rotate by the motor 42, and the drive 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 and conveniently broken up so that they can fully react with the liquid medicine in the deodorizing box 1.

[0056] The method for treating odor in a sewage station using the device described in this embodiment includes the following steps:

[0057] S1. Odor Extraction: Start the vacuum pump 21 installed on the impurity removal box 2. The connected odor hood 22 effectively collects odor and harmful gases in the air surrounding the sewage station and draws 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 and prevents the odor from spreading to the surrounding environment.

[0058] S2. Preliminary Filtration: After entering the impurity removal chamber 2, the odor first passes through the internally mounted filter plate 5, where it undergoes a preliminary filtration process to remove larger particles and impurities. At this point, a scraper 51, slidably mounted on a guide rod 52, comes into close contact with the filter plate 5. Driven by the airflow, the scraper 51 automatically moves with the flow of gas, scraping off impurities adhering to the surface of the filter plate 5 and effectively preventing clogging.

[0059] S3. Activated Carbon Adsorption: The filtered gas is further processed within the impurity removal chamber 2 by an activated carbon adsorption plate 27 mounted in a mounting slot 28. The activated carbon adsorption plate 27, with its powerful adsorption properties, effectively captures volatile organic compounds (VOCs) and other malodorous gas components in the odor, ensuring further purification. A rubber ring 29 secures the activated carbon adsorption plate 27, ensuring stability and easy replacement.

[0060] S4. Spraying the Agent and Decomposing Odors: Activate the liquid pump 31 mounted on the liquid storage tank 3, transferring the oxidant from the tank 3 to the spray assembly 33 via the connecting pipe 32. The oxidant is then evenly sprayed into the interior of the deodorizing tank 1. The oxidant fully contacts the residual gas in the deodorizing tank 1, decomposing the odor into harmless gases through a redox reaction, thus ensuring thorough odor treatment.

[0061] S5. Bubble Breakup and Oxidant Mixing: Motor 42 is activated, driving drive shaft 4, which in turn causes a stirring rod 41 mounted on drive shaft 4 to rotate at high speed within deodorizing chamber 1. Stirring rod 41 breaks up bubbles in the gas, ensuring thorough mixing of the gas and the sprayed oxidant. This stirring process not only improves the reaction efficiency between the gas and liquid but also effectively accelerates the decomposition of odors in the gas.

[0062] S6. Filter Plate Cleaning and Impurity Collection: As the odor passes through the impurity removal box 2, the fan blades 54 rotate, and the adapter plate 55 and the transmission plate 56 work in tandem, driving the scraper 51 up and down along the guide rod 52 to clean any remaining impurities on the filter plate 5. The scraped impurities are pushed into the dust drawer 61 by the scraper 51. The dust drawer 61, through its sliding structure, cooperates with the retaining groove 6, making impurity collection more efficient and facilitating subsequent regular cleaning and maintenance.

[0063] S7. Gas Emission: After the above treatment, the purified gas enters the exhaust hood 25 through the one-way valve 24 installed in the deodorizer 1 and is ultimately discharged to the outside environment through the gas outlet mesh 26. The exhaust hood 25 ensures one-way gas discharge, preventing the backflow of purified gas. Furthermore, the gas outlet mesh 26 is designed to match the exhaust hood 25, further blocking any residual particulate matter and ensuring the cleanliness of the gas discharge.

[0064] S8. Equipment Inspection and Maintenance: Operators should regularly check the condition of the rubber ring 29 and activated carbon adsorption plate 27. If the adsorption effect of the activated carbon adsorption plate 27 weakens, remove the activated carbon adsorption plate 27 from the mounting slot 28 and replace it with a new one to ensure continued good odor adsorption. Also, regularly clean the dust collection drawer 61. Unlock the locking lever 63 by rotating the retaining shaft 62, then remove the dust collection drawer 61 for cleaning to prevent impurities from accumulating and affecting equipment operation.

[0065] Example 2: On the basis of Example 1, in order to facilitate the removal of dust and impurities in the odor, a cleaning mechanism is arranged, including a filter plate 5, which 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 on the rotating shaft 53. The plurality of fan blades 54 are all adapted to the air pump 21. One of them is 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 dust accumulation mechanism includes a limit groove 6, a limit groove 6 is provided on the dust removal box 2, and a dust collection drawer 61 is slidably installed on the inner wall of the limit groove 6. The dust collection drawer 61 is adapted to the scraper 51, and a retaining shaft 62 is installed on the dust removal box 2. The locking rod 63 contacts the outer surface of the dust collection drawer 61, and the gas drawn into the dust removal 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 removal box 2 drives the fan blade 54 on the rotating shaft 53 to rotate, and the fan blade 54 drives the adapter plate 55 to rotate, and the adapter plate 55 drives the transmission plate 56 to move downward, and the transmission plate 56 drives the scraper 51 on the guide rod 52 to move downward on the filter plate 5, and the scraper 51 drives the spring 57 to squeeze, and when the adapter plate 55 is separated from the transmission plate 56, the spring 57 is used to squeeze. The restoring force of the spring 57 drives the scraper 51 to move upward on the filter plate 5, thereby conveniently removing residual impurities on the fan blades 54 and preventing excessive clogging of the filter holes on the fan blades 54 by impurities. At the same time, the impurities cleaned by the scraper 51 on the filter plate 5 will fall into the dust collection drawer 61. After the dust and impurities in the dust collection drawer 61 are fully collected, the locking rod 63 on the retaining shaft 62 can be rotated to release the restraint on the dust collection drawer 61, so that the dust collection drawer 61 can be conveniently pulled out for cleaning, which is convenient for subsequent use. The remaining features are the same as those in Example 1.

[0066] The working principle is as follows: when purifying the odor of the sewage station, first start the switch on the vacuum pump 21, use the vacuum pump 21 to draw the odor of 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. At the same time, the gas blown into the impurity removal box 2 drives the fan blades 54 on the rotating shaft 53 to rotate, and the fan blades 54 drive the adapter plate 55 to rotate, and the adapter plate 55 drives the transmission plate 56 to move downward, and the transmission plate 56 drives the scraper 51 on the guide rod 52 to move downward on the filter plate 5, and the scraper 51 drives the spring 57 to squeeze, and then the filter plate 57 is pressed. 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 too many impurities. At the same time, the impurities cleaned by the scraper 51 on the filter plate 5 will fall into the dust collection drawer 61. After the dust and impurities in the dust collection drawer 61 are fully collected, the locking rod 63 on the retaining shaft 62 can be rotated to release the restraint on the dust collection drawer 61, so that the dust collection 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 broken up, so that they can fully react with the oxidant in the deodorization box 1. The liquid medicine reacts fully. When some bubbles are not broken up 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 is sprayed onto the liquid surface in the deodorizing tank 1 through the spray assembly 33 on the connecting pipe 32, thereby facilitating the oxidation reaction of the gas that exploded on the liquid surface in the deodorizing tank 1 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.

[0067] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
