Description

Technical Field

[0001] This utility model belongs to the field of oil fume purification technology, specifically relating to a vertical device for centralized flue purification in residential communities. Background Technology

[0002] In my country, traditional cooking methods primarily involve frying, stir-frying, roasting, and deep-frying. While these methods impart unique flavors to food, they inevitably lead to the production of large amounts of oil fumes and particulate matter at high temperatures. Typically, oil temperatures can reach 230-250℃. In such high-temperature environments, the moisture in food evaporates rapidly, mixing with the oil to form a complex mixture of oil fumes containing various harmful components such as oil fume molecules, particulate matter, and non-methane hydrocarbons. These pollutants not only affect air quality but may also pose potential threats to human health, such as irritating the respiratory tract and exacerbating cardiopulmonary diseases.

[0003] Due to historical factors, many residential buildings directly discharge cooking fumes from households without purification treatment. Even worse, some communities rely solely on exhaust fans to dissipate these fumes. This not only leads to a pervasive, pungent odor of cooking fumes indoors and in hallways, but also severely pollutes outdoor air quality, resulting in a common "greasy nose" appearance on the exterior walls of building kitchens. The emission of cooking fumes from residential communities directly impacts air quality, severely damaging building appearance and the city's image, and also posing significant fire safety hazards.

[0004] Currently, most urban residential communities lack fume purification devices in their public flue systems, resulting in the direct emission of oily fumes into the environment. Even in communities with fume purification equipment, most employ a multi-flue centralized purification method. This method involves adding branch ducts at each flue outlet, then drawing the fumes through a main duct using a high-power centrifugal fan to a centralized large-scale fume purification unit. However, this method has several drawbacks: the equipment occupies significant rooftop space, installation is complex and costly; to ensure ventilation efficiency, high-volume, high-power fans are required, generating considerable noise and vibration, impacting the quality of life for top-floor residents, and incurring high electricity and equipment maintenance costs. Furthermore, improper construction can damage the roof's waterproofing layer, leading to leaks. While a few vertical fume purifiers are available on the market, their purification principle is mostly adsorption filtration. Due to the high viscosity of oily fumes, the filter media needs frequent replacement; otherwise, filter blockage can easily cause poor ventilation in the public flue, resulting in high maintenance costs.

[0005] Therefore, we propose a vertical centralized flue gas purification device for residential communities to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the technical problems existing in the prior art, this utility model proposes a vertical device for centralized flue gas purification in residential communities.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A vertical flue gas purification device for residential communities includes a mounting frame vertically installed on the outlet of the community's centralized flue gas system. The mounting frame is surrounded by a housing. Inside the mounting frame, from bottom to top, are an atomizing component, a dynamic interceptor, a high-voltage electric field component, and an axial flow fan. The dynamic interceptor is inclined and has an oil-water collection component below it for collecting oil-water mixtures. The oil-water collection component has an oil drain port that extends out of the housing housing. The axial flow fan also extends out of the housing housing.

[0009] In a further technical solution, the dynamic interceptor includes a connecting plate and multiple high-speed centrifugal interception components mounted on the connecting plate. The connecting plate is inclinedly arranged within the mounting connection frame. The high-speed centrifugal interception components include a mounting cylinder, a drive motor, and a separation disc. The mounting cylinder is vertically disposed through the connecting plate. The drive motor is mounted at the tail end of the mounting cylinder, and the separation disc is mounted on the output shaft of the drive motor.

[0010] In a further technical solution, the oil-water collection assembly includes an oil receiving ring and an oil receiving box. The oil receiving ring is sleeved on the outside of the separating disc and connected to the connecting plate. A notch is provided below the oil receiving ring. The oil receiving box is connected to the notch of the oil receiving ring and connected to the connecting plate. The oil leakage port is provided on the oil receiving box.

[0011] In a further technical solution, the atomizing component includes a water pipe and a plurality of atomizing nozzles disposed on the water pipe. The water pipe is located below the connecting plate and is arranged parallel to the connecting plate, and the atomizing nozzles are arranged facing the separation disc.

[0012] In a further technical solution, both ends of the high-voltage electric field component are provided with wind distribution networks, and the high-voltage electric field component includes two sets of high-voltage electric field generators, which are arranged vertically.

[0013] In a further technical solution, an opening is provided on one side of the housing shell, and a matching maintenance door or electrical control box is hinged to the opening.

[0014] In a further technical solution, the top surface of the housing is provided with an extension frame, and a rain cap is provided on the extension frame.

[0015] In a further technical solution, louvers are provided on the outer side of the extended frame.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model has a simple and compact structure and is easy to install. By installing the device vertically on the centralized flue outlet of the community, it does not require occupying the common area of ​​the community owners and avoids leakage problems caused by large-scale damage to the roof waterproof layer.

[0018] 2. This utility model uses a dynamic interceptor and a high-voltage electric field component to purify oil fumes, ensuring efficient purification of oil fumes and making the emitted oil fumes strictly comply with environmental protection regulatory standards. This effectively reduces the pollution of the environment caused by oil fume emissions, which is in line with the concept of green ecology. At the same time, by using a dynamic interceptor and a high-voltage electric field component to purify oil fumes, there is no need to frequently replace the filter material, and the problem of clogging is avoided, thus ensuring smooth exhaust of public flues.

[0019] 3. The axial flow fan used in this utility model has low power, low noise and low vibration during operation, and will not affect the residents on the top floor, thus significantly reducing energy consumption and maintenance costs.

[0020] 4.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figures 1-4 This utility model provides a vertical device for centralized flue gas purification in residential communities, including a mounting frame 1 vertically installed on the outlet of the centralized flue gas in the community. The outer side of the mounting frame 1 is surrounded by a housing shell 2. Inside the mounting frame 1, from bottom to top, atomizing component 3, dynamic interceptor 4, high-voltage electric field component 5, and axial flow fan 6 are installed sequentially. The dynamic interceptor 4 is inclined and has an oil-water collection component 7 for collecting oil-water mixture below it. The oil-water collection component 7 has an oil drain port 8 that extends out of the housing shell 2. The axial flow fan 6 extends out of the housing shell 2.

[0030] This equipment is suitable for both the renovation of old residential areas and the installation of new residential areas. Its workflow for handling oil and fume mixtures in centralized flues within residential areas is as follows:

[0031] When a mixture of oil and fumes needs to be discharged from the centralized flue of the residential area, the axial flow fan 6 immediately starts. The oil and fumes enter the equipment from the outlet of the centralized flue, first passing through the atomizing component 3. The water mist sprayed by the atomizing component 3 comes into contact with the oil and fumes, which not only cools the mixture but also, through the principle of inertial impaction, causes most of the oil and fume particles to tightly combine with water mist molecules and condensate, forming growth nuclei. Under the action of the viscosity and surface tension of liquid water, these growth nuclei can more effectively adsorb nearby particulate matter, grease, water vapor and other solid and liquid phase substances, thus forming larger aggregates, greatly increasing the probability of successful interception by the dynamic interceptor 4. Next, the oil and fumes continue to rise and enter the dynamic interception area. Here, most of the oil and fumes are effectively intercepted by the dynamic interceptor 4, forming an oil-water mixture of oil droplets, water droplets and impurities. Because the dynamic interceptor 4 adopts an inclined design, typically installed at a 30° angle, the intercepted oil-water mixture is thrown out under centrifugal force and collected by the oil-water collection component 7 below, preventing the oil-water mixture from falling back into the flue. Finally, it is periodically discharged from the outer casing 2 through the oil drain 8 for subsequent processing. Afterwards, the oil fume mixture that is not intercepted by the dynamic interceptor 4 continues to rise and enters the high-voltage electric field purification stage. Here, the high-voltage electric field component 5 utilizes a high-voltage electric field to deeply purify the oil fumes through ionization, decomposition, adsorption, and carbonization processes, ensuring that the oil fumes do not leak out and further improving the purification effect. Finally, the air, after undergoing multiple purification processes, is safely discharged into the atmosphere by the axial flow fan 6. Compared to traditional oil fume purification technologies, this equipment has a simple and compact structure and is easy to install. By installing the equipment vertically on the centralized flue outlet of the community, it does not occupy the common area of ​​the community residents and avoids leakage problems caused by large-scale damage to the roof waterproofing layer. This equipment purifies oil fumes through a dynamic interceptor 4 and a high-voltage electric field component 5, ensuring highly efficient purification and guaranteeing that emissions strictly comply with environmental regulations. This effectively reduces environmental pollution from oil fume emissions, aligning with green ecological principles. Furthermore, the use of the dynamic interceptor 4 and high-voltage electric field component 5 eliminates the need for frequent filter replacements and avoids clogging issues, ensuring smooth exhaust from public flues. In addition, the axial flow fan 6 used in this equipment has low power consumption, resulting in low noise and vibration during operation, minimizing impact on top-floor residents and significantly reducing energy consumption and maintenance costs. Notably, the atomizing component 3 not only provides water mist for the oil fume purification process but also washes the dynamic interceptor 4, effectively extending the equipment's maintenance cycle and significantly reducing cleaning frequency and operating costs, providing an economical and efficient solution to the oil fume treatment problem.

[0032] In one specific implementation, see Figure 1 , Figure 3 and Figure 4The dynamic interceptor 4 includes a connecting plate 401 and multiple high-speed centrifugal interception components mounted on the connecting plate 401. The connecting plate 401 is inclinedly disposed within the mounting and connecting frame 1. The high-speed centrifugal interception components include a mounting cylinder 402, a drive motor 403, and a separation disk 404. The mounting cylinder 402 is vertically disposed through the connecting plate 401. The drive motor 403 is mounted at the tail end of the mounting cylinder 402. The separation disk 404 is mounted on the output shaft of the drive motor 403.

[0033] As a core component of the equipment, the dynamic interceptor 4 plays a crucial role in oil fume purification. Specifically, during operation, the separation disc 404, driven by the drive motor 403, utilizes principles such as dynamic mechanical shielding, physical centrifugal removal, and eddy current effect. Through high-speed rotation, it generates an intercepting motion that violently collides with particulate matter in the oil fume mixture. This process intercepts a large amount of solid and liquid substances such as particulate matter and water vapor in the oil fume mixture, which are then separated by centrifugation and collected by the oil-water collection component 7 below. Finally, the oil is periodically discharged from the outer shell 2 of the housing through the oil drain 8 for subsequent processing.

[0034] In one specific implementation, see Figure 4 The oil-water collection assembly 7 includes an oil receiving ring 701 and an oil receiving box 702. The oil receiving ring 701 is sleeved on the outside of the separating disc 404 and connected to the connecting plate 401. A notch is provided below the oil receiving ring 701. The oil receiving box 702 is connected to the notch of the oil receiving ring 701 and is connected to the connecting plate 401. The oil leakage port 8 is provided on the oil receiving box 702.

[0035] The oil-water collection assembly 7, through the cooperation of the oil receiving ring 701 and the oil receiving box 702, ensures that during the operation of the dynamic interceptor 4, the oil-water mixture separated by centrifugal force from the separating disc 404 is thrown into the oil receiving ring 701. Under the action of gravity, the oil-water mixture slides down the inner wall of the oil receiving ring 701 and flows into the oil receiving box 702 through the lower notch, completing the unified collection of the oil-water mixture. Finally, the oil-water mixture can be periodically discharged from the outer shell 2 of the tank through the oil drain port 8 on the oil receiving box 702, reducing the difficulty of subsequent treatment.

[0036] In one specific implementation, see Figure 3 The atomizing component 3 includes a water pipe 301 and a plurality of atomizing nozzles 302 disposed on the water pipe 301. The water pipe 301 is located below the connecting plate 401 and is arranged parallel to the connecting plate 401. The atomizing nozzles 302 are arranged toward the separation plate 404.

[0037] By connecting water pipe 301 to tap water pipe 301, during the oil fume purification process, multiple atomizing nozzles 302 work simultaneously to convert the water in water pipe 301 into water mist. This water mist fully contacts and combines with the oil fume mixture, effectively reducing the temperature of the oil fume and increasing the probability of it being intercepted by the dynamic interceptor 4 by forming a larger atomized mixture, thereby improving the oil fume purification effect. Furthermore, the atomizing nozzles 302 are aimed at the separation disc 404, and while spraying water mist, they also clean the separation disc 404, effectively reducing the adhesion of oil fume to the separation disc 404. This reduces the frequency of equipment cleaning, lowers maintenance costs, and ensures the long-term cleanliness and efficient operation of the equipment.

[0038] In one specific implementation, see Figure 1 Both ends of the high-voltage electric field component 5 are provided with wind distribution nets 9. The high-voltage electric field component 5 includes two sets of high-voltage electric field generators, which are arranged vertically.

[0039] By installing air distribution nets 9 at both ends of the high-voltage electric field component 5, precise control and optimization of airflow are achieved. Specifically, the front-end air distribution net 9 first contacts the airflow entering the high-voltage electric field component 5, effectively regulating the airflow distribution and ensuring that the airflow entering the high-voltage electric field component 5 is uniform and stable. This lays a solid foundation for the uniform capture and efficient purification of oil fume particles by the high-voltage electric field component 5. The rear-end air distribution net 9 plays a role in stabilizing the airflow output. At the outlet of the high-voltage electric field component 5, the airflow may experience unstable phenomena such as eddies or backflow due to the electric field. The rear air distribution net 9 effectively reduces these eddies and backflows, ensuring smooth airflow output. In addition, the high-voltage electric field component 5 employs two sets of high-voltage electric field generators to achieve a dual purification mechanism, ensuring that oil fume particles are fully charged and effectively adsorbed during the purification process, thereby effectively improving the purification effect. Moreover, by dispersing the load pressure of a single high-voltage electric field generator, the performance degradation or failure risk caused by prolonged high-load operation is effectively avoided, improving the user experience.

[0040] In one specific implementation, see Figures 1-3 The outer shell 2 of the box has an opening on one side, and a matching maintenance door 13 is hinged to the opening.

[0041] The presence of the access door 13 greatly facilitates the daily maintenance and troubleshooting of the equipment. Workers can easily access the internal components by simply opening the access door 13, without disassembling the entire outer casing 2, to perform necessary inspections, repairs, or replacements, thus significantly reducing maintenance difficulty and time costs. Furthermore, by installing the electrical control components inside the access door 13, it not only fulfills its basic maintenance access function but also serves as an electrical control box. This not only meets the basic needs of equipment maintenance but also effectively improves the space utilization of the equipment, making the overall layout more compact and tidy.

[0042] In one specific implementation, see Figures 1-3 The top surface of the outer shell 2 of the box is provided with an extension frame 10, and the extension frame 10 is provided with a rain cap 11.

[0043] The rain cap 11 features a conical design that allows for rapid drainage, providing an effective rain barrier for the equipment and preventing rainwater from seeping into the interior. This protects internal components from moisture and corrosion, ensuring the long-term stable operation of the equipment.

[0044] In one specific implementation, see Figure 2 and Figure 3 The outer side of the extended frame 10 is provided with louvers 12.

[0045] The design of the louver 12 not only serves as a channel for equipment exhaust, meeting the actual needs of equipment exhaust, but also enhances the overall aesthetics and visual effect of the equipment.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
