Description

Technical Field

[0001] This application relates to the field of air-supported membrane equipment, specifically to a dust removal method, system, and equipment for air-supported membrane equipment. Background Technology

[0002] Air-supported membrane structures use special architectural fiber membrane materials as their outer shell. An automated pressurization and fresh air system supports this "shell" to form an architectural space, integrating technologies such as architecture, structural mechanics, new materials science, mechatronics, and automatic control. The air-supported membrane structure relies on the pressure difference between the inside and outside to support the entire structure. Due to the flexibility of the materials, the inherent effectiveness of the structure, and its curved shape, there are no components subjected to bending, torsion, or compression, and no internal frame or beam / column support is required. As atmospheric pressure increases, the oxygen content in the environment increases; therefore, the pressure difference between the inside and outside of the air-supported membrane not only has no adverse effects on the human body but also helps people engage in sports activities or physical labor.

[0003] In recent years, with the increasingly widespread application of air-supported membrane structures in the industrial field, the problem of dust removal inside these structures has become increasingly prominent. Due to the strong sealing of air-supported membrane structures and the low frequency of ventilation, internal air circulation is poor, and dust easily accumulates. Ineffective internal dust removal not only affects the air quality of the working environment but also damages equipment and workpieces, and even endangers the health of workers. Summary of the Invention

[0004] This application provides a dust removal method, system, and device for an air-supported membrane structure, to solve at least one of the technical problems in the background art. The specific solution is as follows:

[0005] In its first part, this application proposes a dust removal method for an air-supported membrane structure, wherein the air-supported membrane structure involves at least a membrane material, an electrostatic dust removal device, a spraying device, and a water supply device connecting each spraying device, wherein the spraying devices are distributed along the seam lines between the membrane materials, and the dust removal method includes: Based on the distribution of the seam lines and the spray device, the internal space of the air film equipment is pre-divided into multiple dust removal zones, so that each dust removal zone involves all seam lines and has a spray device; Dust samples were collected and analyzed in each dust removal zone to obtain the dust composition and the proportion of each component in each dust removal zone, and the temperature and dust concentration in each dust removal zone were monitored in real time. When the dust concentration in any dust removal zone exceeds the preset concentration, analyze the specific gravity of fibrous dust and corrosive dust in that zone, and select the appropriate dust removal solution: If the specific gravity of the fiber dust is greater than the preset first specific gravity, the dust removal scheme includes: detecting the temperature of the dust removal area, and selecting whether to turn on the spray device to perform spray dust removal based on the temperature; If the specific gravity of the corrosive dust is greater than the preset second specific gravity, the dust removal scheme includes: detecting the air flow rate in the dust removal area, and selecting whether to turn on the electrostatic dust removal equipment for electrostatic dust removal based on the air flow rate.

[0006] In some specific embodiments, if the specific gravity of the fiber dust is greater than the first specific gravity, then if the current temperature of the dust removal area is not higher than the preset temperature, the spray device of the dust removal area shall be turned on at least. First, water flow shall be output to the spray device at a preset first water pressure to perform self-cleaning of the spray device, and then water flow shall be output to the spray device at a preset second water pressure lower than the first water pressure to perform spray dust removal. If the specific gravity of the corrosive dust is greater than the second specific gravity, the gas flow between the air film equipment and the external environment is reduced, and if the current air velocity in the dust removal area is not higher than the preset velocity, the electrostatic dust removal equipment is started to perform electrostatic dust removal in the dust removal area, and combined with manual dust removal to complete the removal of corrosive dust in the dust removal area.

[0007] In some specific embodiments, if the specific gravity of the fiber dust does not exceed the first specific gravity and the specific gravity of the corrosive dust does not exceed the second specific gravity, the electrostatic dust removal equipment is first started to perform electrostatic dust removal on the dust removal area. After the electrostatic dust removal is completed, the spray device of the dust removal area is turned on, and water is output to the spray device at a preset second water pressure for spray dust removal.

[0008] In some specific embodiments, the interior of each dust removal zone is scanned by one or more infrared imaging devices to analyze the attenuation of infrared radiation and thus calculate the concentration and particle size distribution of dust. Alternatively, assuming a stable flow field inside the air-film equipment, the dust concentration can be calculated by measuring the changes in vibration frequency caused by dust particles in the gas within each dust removal zone.

[0009] In some specific embodiments, if the current temperature of the dust removal area is higher than the preset temperature, the gas flow between the air film equipment and the external environment is increased, and all spray devices are turned on to output cold water to each spray device for cooling until the current temperature of the dust removal area is lower than the preset temperature.

[0010] In some specific embodiments, the distance between each dust removal zone and the water supply device increases sequentially, and the second water pressure of the spray device in each dust removal zone is set according to the distance, so that the second water pressure corresponding to the spray device in the dust removal zone that is farther away from the water supply device is greater.

[0011] Part Two, this application proposes a dust removal system for an air-supported membrane device, comprising: The area division unit is used to pre-divide the internal space of the air-supported membrane equipment into multiple dust removal zones based on the distribution of seam lines and spray devices, so that each dust removal zone involves all seam lines and has a spray device; The analysis and monitoring unit is used to collect dust samples from each dust removal zone, analyze the dust composition based on the dust samples, and monitor the temperature and dust concentration of each dust removal zone in real time.

If the specific gravity of the fiber dust is greater than the preset first specific gravity, the dust removal scheme includes: detecting the temperature of the dust removal area, and selecting whether to turn on the spray device to perform spray dust removal based on the temperature; If the specific gravity of the corrosive dust is greater than the preset second specific gravity, the dust removal scheme includes: detecting the air velocity in the dust removal area, and selecting whether to turn on the preset electrostatic dust removal equipment for electrostatic dust removal based on the air velocity.

[0012] In some specific embodiments, the dust removal unit includes: If the specific gravity of the fiber dust is greater than the first specific gravity, then if the current temperature of the dust removal area is not higher than the preset temperature, the spray device of the dust removal area shall be turned on at least. First, water flow shall be output to the spray device at a preset first water pressure to perform self-cleaning of the spray device, and then water flow shall be output to the spray device at a preset second water pressure lower than the first water pressure to perform spray dust removal. If the specific gravity of the corrosive dust is greater than the second specific gravity, the second dust removal unit reduces the gas flow between the air film equipment and the external environment. If the current air velocity in the dust removal area is not higher than the preset velocity, the electrostatic dust removal equipment is activated to perform electrostatic dust removal in the dust removal area, and combined with manual dust removal, the removal of corrosive dust in the dust removal area is completed. In the third dust removal unit, if the specific gravity of fiber dust does not exceed the first specific gravity and the specific gravity of corrosive dust does not exceed the second specific gravity, the electrostatic dust removal equipment is first started to perform electrostatic dust removal on the dust removal area. After the electrostatic dust removal is completed, the spray device of the dust removal area is turned on, and water is output to the spray device at the second water pressure for spray dust removal.

[0013] Part Three, this application proposes an air-supported membrane device for implementing the dust removal method described in any one of Part One, comprising an air-supported membrane body and a ventilation system, a first dust removal system, and a second dust removal system connected to the air-supported membrane body; the first dust removal system includes a water supply device, pipes, and multiple spray devices; the second dust removal system includes an electrostatic dust removal device; The water supply device is connected to each spray device through the pipeline, and is used to output water flow to the spray device at different water pressures; The air-supported membrane body is provided with multiple spliced ​​membrane materials. The air-supported membrane body is fixedly connected to a preset installation surface and forms an internal space with the installation surface. The ventilation system is used to circulate air between the internal space and the external environment. The internal space is divided into multiple dust removal zones according to the seam lines between the membrane materials. Temperature detection devices and dust detection devices are installed in some or all of the dust removal zones. At least a portion of the pipes are detachably connected to the inner wall of the air-supported membrane body via multiple fixing mechanisms; each of the fixing mechanisms is distributed at the joints between the membrane materials; The spraying device is located at the fixed mechanism and is used to spray liquid to achieve dust removal.

[0014] In some specific embodiments, the fixing mechanism includes a first fixing member and a second fixing member fixedly connected to each other; at least a portion of the first fixing member is fixedly connected to the inner wall of the air-supported membrane body; the second fixing member is fixedly disposed on the portion of the first fixing member located on the inner wall of the air-supported membrane body and is detachably fixedly connected to the pipeline; the first fixing member includes a connecting structure, a first plate structure located on the inner wall of the air-supported membrane body, and a second plate structure located on the outer wall of the air-supported membrane body, and the second fixing member is fixedly connected to the first plate structure; a connecting hole is provided through the air-supported membrane body, and the connecting structure is detachably connected to the first plate structure and the second plate structure through the connecting hole.

[0027] Example 1 This embodiment provides a dust removal method for an air-supported membrane device. A flowchart of the dust removal method is attached. Figure 1 As shown, the specific solution is as follows: A dust removal method for an air-supported membrane structure, applicable to air-supported membrane structures involving at least membrane materials, electrostatic dust removal equipment, a spraying device, and a water supply device, wherein the spraying device is distributed along the seam lines between the membrane materials, and the dust removal method includes the following steps: 101. Based on the distribution of seam lines and spray devices, the internal space of the air-supported membrane equipment is pre-divided into multiple dust removal zones, so that each dust removal zone covers all seam lines and has a spray device; 102. Collect and analyze dust samples from each dust removal zone to obtain the dust composition and proportion of each component in each dust removal zone, and monitor the temperature and dust concentration in each dust removal zone in real time. 103. When the dust concentration in any dust removal zone exceeds the preset concentration, analyze the specific gravity of fibrous dust and corrosive dust in that dust removal zone, and select the appropriate dust removal scheme: If the specific gravity of the fiber dust is greater than the preset first specific gravity, the dust removal scheme includes: detecting the temperature of the dust removal area, and selecting whether to turn on the spray device for spray dust removal based on the temperature; If the specific gravity of the corrosive dust is greater than the preset second specific gravity, the dust removal scheme includes: detecting the air velocity in the dust removal area, and selecting whether to turn on the electrostatic dust removal equipment for electrostatic dust removal based on the air velocity.

[0028] Specifically, if the specific gravity of the fiber dust is greater than the first specific gravity, then if the current temperature of the dust removal zone is not higher than the preset temperature, the spray device of the dust removal zone shall be turned on at least. First, water flow shall be output to the spray device at a preset first water pressure to perform self-cleaning of the spray device, and then water flow shall be output to the spray device at a preset second water pressure lower than the first water pressure to perform spray dust removal.

[0029] Specifically, if the specific gravity of the corrosive dust is greater than the second specific gravity, the gas flow between the air film equipment and the external environment is reduced, and if the current air velocity in the dust removal area is not higher than the preset velocity, the electrostatic dust removal equipment is started to perform electrostatic dust removal in the dust removal area, and combined with manual dust removal to complete the removal of corrosive dust in the dust removal area.

[0030] If the specific gravity of the fibrous dust does not exceed a preset first specific gravity, and the specific gravity of the corrosive dust does not exceed a preset second specific gravity, the electrostatic precipitator is first activated to perform electrostatic dust removal in the dust removal area. After electrostatic dust removal is completed, the spray device in the dust removal area is activated, and water is output at the second water pressure to the spray device for spray dust removal. Solid dust is removed by the electrostatic precipitator, and non-solid dust is removed by the spray device, improving dust removal quality and reducing subsequent collection processes and collection costs.

[0031] This application addresses the specific dust composition in air-supported membrane equipment by employing suitable dust removal methods. These methods include spray dust removal, electrostatic dust removal, and ventilation filtration dust removal. Electrostatic dust removal utilizes electrostatic adsorption to remove dust particles, offering high removal efficiency and effectiveness for solid particles. Spray dust removal uses liquid to wash the dust-laden airflow, causing dust particles to collide with the liquid film, droplets, or bubbles, resulting in adsorption, agglomeration, and discharge with the liquid. This method is suitable for handling large volumes of dust-laden gas but requires wastewater treatment. Ventilation filtration dust removal, also known as mechanical dust removal, uses mechanical ventilation to expel dust from the air-supported membrane equipment outdoors, while filter media removes airborne dust particles.

[0032] This application divides the internal space of the air-supported membrane structure into multiple dust removal zones for zoned control. Targeted dust removal control is implemented based on the dust concentration and dust removal requirements of each zone, allowing for flexible adjustments based on the actual needs and changes of the air-supported membrane structure. This approach more effectively removes dust from different zones, rationally allocates the operating time and power of the dust removal equipment, improves the overall dust removal efficiency of the air-supported membrane structure, and reduces management complexity, facilitating independent monitoring and adjustment of each zone. Furthermore, as the use and needs of the air-supported membrane structure change, it may be necessary to add or remove dust removal equipment; zoned dust removal control allows for easy expansion or reduction of each zone.

[0033] This application divides the dust removal zone based on the seam lines and spray devices. The membrane material is the main structural material of the air-supported membrane equipment, possessing certain strength and toughness to withstand external forces such as wind and rain, while also exhibiting good thermal insulation properties. The air-supported membrane body has multiple spliced ​​membrane materials, with the connection points between the membrane materials being the seam lines. These seam lines are fixed by multiple seam nodes to achieve the connection between the membrane materials. Spray devices are distributed along the seam lines and located at each seam node. Since the seam nodes require additional fixing mechanisms, modifications to the membrane material are necessary. Installing spray devices at the seam nodes allows for full utilization of the fixing mechanisms to secure the spray devices and pipes, reducing secondary modifications to the membrane material and ensuring the airtightness of the air-supported membrane equipment.

[0034] The seam line can be understood as a long arc, and the seam nodes are multiple points on this arc. When dividing the dust removal zone, it is not done along the seam line itself, but rather by dividing the seam line into multiple parts. Each part of the seam line is connected to form a dust removal zone. For example, the midpoint of each seam node is selected, and midpoints at the same horizontal level or within the same horizontal level range are connected to construct a straight line or polygonal line connecting all the seam lines. The area formed by adjacent straight lines or polygonal lines constitutes a dust removal zone. In this application, it is necessary to ensure that each dust removal zone has a spraying device and covers all the seam lines. In practical applications, the membrane materials of air-supported membrane equipment are mostly of the same structure, and the dust removal zone can be directly divided along the perpendicular line of the seam line on the membrane material. A schematic diagram of the dust removal zone division is attached. Figure 2 As shown. In Figure 2 In the diagram, C1-C5 represent different dust removal zones, and each dust removal zone involves all seam lines.

[0035] In step 102, dust samples from each dust removal zone need to be collected and analyzed to obtain the dust composition and proportion of each component in each zone, as well as the temperature and dust concentration in each zone in real time. The solution in this application obtains the specific composition of the dust by collecting and analyzing dust samples. In practical applications, the various types of dust that may exist inside the air-supported membrane equipment can be known in advance based on the dust sources. After collecting the dust samples, the dust composition can be obtained simply by analyzing the characteristics of each dust particle.

[0036] For example, specialized sampling equipment, such as a dust sampler, is used to collect dust samples from different areas within the air-supported membrane structure. The sampling equipment is ensured to be calibrated to guarantee the accuracy of the measurement results. The collected dust samples are pre-processed, including impurity removal, grinding, and sieving, for subsequent analysis. Chemical analysis methods, such as X-ray diffraction, infrared spectroscopy, and atomic absorption spectroscopy, are used to analyze the composition of the dust samples. These methods can determine the types and contents of various elements in the dust. A particle size analyzer is used to measure the particle size distribution of the dust samples. By measuring the number or mass of dust particles in different size ranges, the proportion of dust particles of various sizes can be determined. The chemical composition and particle size distribution data are compiled into tables or charts for comparison and analysis. By comparing data from different areas and at different time points, the changing trends in the proportion of various types of dust can be understood. Based on the data analysis and comparison results, conclusions are drawn regarding the proportion of various types of dust within the air-supported membrane structure. Based on these conclusions, corresponding control measures can be developed to reduce the emission of certain types of dust or strengthen their treatment. For example, the proportion of dust components can be obtained by calculating the percentage of each component in the total dust content in each dust sample and then taking the average value.

[0037] When the dust concentration in any dust removal zone exceeds a preset concentration, it indicates that dust removal is required for that zone. Dust concentration detection methods include infrared detection, vibration detection, or a dedicated dust detector. A dust detector typically consists of a sampling head, a measuring section, and a display, enabling rapid measurement and display of dust concentration. In some specific embodiments, dust concentration can be measured simultaneously during dust sample collection and analysis; however, this method requires time and cannot meet real-time requirements. In practical applications, dust concentration measurement is not necessary every time. The proposed method can be used continuously after a single dust component measurement, provided the overall environment remains unchanged. Dust concentration detection methods require a certain level of real-time performance, while manual sampling and detection have a certain time delay.

[0038] In some specific embodiments, the interior of each dust removal zone is scanned using one or more infrared imaging devices to analyze the attenuation of infrared radiation and thus calculate the dust concentration and particle size distribution. When dust particles are present in the gas, they absorb and scatter infrared radiation, leading to energy attenuation. By using a highly sensitive infrared imager to scan the interior of the air-film device, the attenuation of infrared radiation can be observed, thereby calculating the dust concentration and particle size distribution.

[0039] In some specific embodiments, under the premise of stable internal flow field of the air-film device, the dust concentration is calculated by measuring the change in vibration frequency caused by dust particles in the gas of each dust removal zone. When dust particles are present in the gas, the interaction between the particles and gas molecules will generate a certain vibration frequency, and the change in this frequency can be detected by a specific sensor. By measuring this frequency change, the dust concentration can be calculated. The dust concentration detection scheme of this application needs to be applicable to online and real-time monitoring, and have the ability to detect quickly and with high precision.

[0040] This application requires targeted dust removal based on specific dust components. For example, corrosive dust must be prevented from leaking into the external environment, and spray dust removal cannot be used, as corrosive dust dissolved in water and adhering to specific structures may cause corrosion to the equipment. Therefore, it is necessary to understand the specific composition of corrosive dust in order to select appropriate protective measures and cleaning methods. This application employs different adaptive dust removal methods for corrosive dust and fibrous dust. Fiber dust easily clogs spray devices, and this problem needs to be addressed appropriately.

[0041] There are several reasons for the generation of fibrous dust within air-supported membrane structures. During the processing, transportation, and use of fibrous materials, physical or chemical actions such as mechanical friction, cutting, tearing, and collision cause the fibrous materials to break or decompose into fine dust particles. Additionally, the raw materials used in some scenarios may themselves contain a certain amount of fibrous dust, such as natural fibers like cotton and wool in the textile industry. Fibrous dust mainly includes: natural fibers (e.g., cotton, wool, flax); man-made fibers (e.g., polyester, nylon, glass fiber); and textile fibers (e.g., fabrics, carpets, curtains). Fiber dust is primarily generated in industrial production processes such as textiles, furniture making, printing, spraying, and chemical fiber production. Large amounts of fibrous dust are generated during the processing, transportation, and use of fibrous materials. For example, the processing of natural fibers like cotton, wool, and flax in the textile industry generates a large amount of fine fibrous dust; the processing of wood and fabrics in furniture making also generates fibrous dust; and the pigments and coating materials used in printing and spraying processes produce fibrous dust.

[0042] When the dust concentration in any dust removal zone exceeds a preset concentration, analyze whether the specific gravity of the fiber dust in that zone is greater than a preset first specific gravity. Specific gravity is the average proportion of fiber dust in the dust sample. The first specific gravity can be set according to the actual application scenario, as the generation rate of fiber dust may vary in different application scenarios. If so, detect the current temperature of the dust removal zone. If the current temperature of the dust removal zone is not higher than a preset temperature, at least turn on the spray device of that dust removal zone. First, output water at a preset first water pressure to the spray device for self-cleaning, and then output water at a preset second water pressure lower than the first water pressure to the spray device for dust removal.

[0043] When starting the spray system for dust removal, the internal temperature of the air-supported membrane equipment must be considered. Direct contact between water mist and high-temperature gas will generate water vapor, reducing the water mist's adsorption capacity and resulting in poor dust removal efficiency. Therefore, dust removal needs to be carried out under suitable temperature conditions. In some specific embodiments, if the current temperature of the dust removal area is higher than a preset temperature, the operating power of the ventilation system within the air-supported membrane equipment is increased to increase airflow, and all spray systems are activated, outputting cold water to each spray system for cooling until the current temperature of the dust removal area is lower than the preset temperature. Furthermore, the cooling system inside the air-supported membrane equipment, such as an air conditioner, can be upgraded to achieve rapid cooling.

[0044] Because fibrous dust easily clogs the nozzles of spray dust suppression systems, affecting the spraying effect, this application uses water pressure control to first perform self-cleaning to remove dust from the nozzles before dust suppression. In practical applications, a higher water pressure is first used to clean the dust clogging the nozzles, and then normal water pressure is used for spray dust suppression. Therefore, the first water pressure will be greater than the second water pressure, which needs to be set according to the pressure required by the specific spraying device. The first water pressure should be at least 20% higher than the second water pressure.

[0045] Corrosive dust mainly originates from various industrial production and processing processes within a space, such as chemical reactions, metal smelting, casting, and pharmaceutical manufacturing. The dust generated during these production and processing processes contains corrosive substances, such as acids, alkalis, and salts, which can irritate or corrode human skin, respiratory system, and eyes.

[0046] In this application, when the dust concentration in any dust removal zone exceeds a preset concentration, the specific gravity of corrosive dust in that dust removal zone is analyzed to determine if it is greater than a preset second specific gravity. If so, it is necessary to ensure the stability of the flow field in the dust removal zone, reducing the flow of corrosive dust to other dust removal zones while also preventing corrosive dust from remaining in the external environment. This can be achieved by reducing the power of the ventilation system to decrease the gas flow between the air film equipment and the external environment. Furthermore, when the current air velocity in the dust removal zone is not higher than a preset velocity, a preset electrostatic precipitator is activated to perform electrostatic dust removal in that zone, combined with manual dust removal to complete the removal of corrosive dust.

[0047] When removing corrosive dust, a closed-loop cleaning system should be adopted to minimize the leakage of corrosive dust from the air-film equipment and its impact on the external environment. Therefore, it is necessary to reduce gas exchange within the air-film equipment. Furthermore, to ensure efficient dust removal during electrostatic precipitators, it is crucial to maintain a stable airflow field, thus requiring a reduction in the operating power of the ventilation system. Additionally, since corrosive dust, when mixed with mist, may fall onto the surface of the equipment and cause corrosion, spray dust removal is not suitable. Electrostatic precipitators can reduce the corrosive effects of corrosive dust on the air-film equipment. Electrostatic precipitators utilize the principle of electrostatic adsorption to remove dust particles from the air. A high-voltage electric field charges the dust particles, causing them to adhere to the collection plate. A rapping device then shakes the adsorbed dust particles off and collects them. Electrostatic precipitators can efficiently remove dust and harmful substances from the air, providing stable purification results and low maintenance costs.

[0048] In this application, the spray devices are distributed along the seams. To ensure sufficient water pressure, the location of the water supply devices needs to be rationally set. In some specific embodiments, the water supply device is located at one end of the seam line. The pipeline includes a main pipeline and branch pipelines, with the branch pipelines distributed along the seam line. The main pipeline is located at the break points of each seam line and connects to each branch pipeline. The water supply device is located on the centerline of the main pipeline to ensure sufficient water pressure for the edge spray devices. In some specific embodiments, the distance between each dust removal zone and the water supply device increases sequentially. The second water pressure of the spray devices in each dust removal zone is set according to the distance, so that the second water pressure corresponding to the spray devices in the dust removal zone farther away from the water supply device is greater. The greater the second water pressure, the greater the water supply pressure of the water supply device. (See Appendix...) Figure 2 In the process, the distance between C1-C5 and the water supply device increases sequentially. Therefore, the water supply pressure to the dust removal zone C5 should be significantly greater than that to the dust removal zone C1.

[0049] This embodiment provides a dust removal method for air-supported membrane equipment, which integrates multiple dust removal schemes, fully considers factors such as dust composition and concentration, and adopts the most suitable dust removal scheme to achieve intelligent zoned dust removal, significantly improving dust removal efficiency, reducing energy consumption and costs, reducing secondary pollution, and improving the safety and flexibility of dust removal. It can better adapt to changes and needs in production processes and is suitable for various air-supported membrane equipment application scenarios.

[0050] Example 2 This embodiment provides an air-supported membrane device for implementing the dust removal method in Embodiment 1. The structure of the air-supported membrane device is shown in the attached instruction manual. Figure 2-4 As shown, the specific solution is as follows: An air-supported membrane device includes an air-supported membrane body B1 and a ventilation system B2, a first dust removal system B3, and a second dust removal system B4 connected to the air-supported membrane body B1, as shown in the attached figure. Figure 5 As shown; the first dust removal system B3 includes a water supply device 2, pipes 4, and multiple spray devices 3; the second dust removal system B4 includes an electrostatic dust removal device; the water supply device 2 is connected to each spray device 3 through pipes 4, and is used to output water flow to the spray devices 3 at different water pressures; the air-supported membrane body B1 is provided with multiple spliced ​​membrane materials 11, the air-supported membrane body B1 is fixedly connected to the preset installation surface and forms an internal space with the installation surface, the ventilation system B2 is used to circulate air between the internal space and the external environment; the internal space is divided into multiple dust removal zones according to the splicing lines between the membrane materials 11, and some or all of the dust removal zones are provided with temperature detection devices and dust detection devices; at least some of the pipes 4 are detachably connected to the inner wall of the air-supported membrane body B1 through multiple fixing mechanisms; each fixing mechanism is distributed at the connection between the membrane materials 11; the spray devices 3 are located at the fixing mechanisms and are used to spray liquid to achieve dust removal.

[0051] For example, the air-supported membrane structure B1 is constructed from multiple parts, including membrane material 11, a support system, a control system, and an anchoring system. Membrane material 11 is the main structural material of the air-supported membrane equipment, possessing certain strength and toughness to withstand external forces such as wind and rain, while also having good thermal insulation properties. Multiple interconnected membrane materials 11 are provided on the air-supported membrane structure B1. The connection points between membrane materials 11 are seams, which are fixed by multiple seam nodes to achieve the connection between the membrane materials 11. The support system, as the skeleton structure of the air-supported membrane equipment, can use steel cables, rigging, or other structures to fix and support the membrane materials 11. The ventilation system B2 includes air inlets, exhaust outlets, and fans, used to regulate the freshness and temperature of the indoor air, and also serves as ventilation. The control system connects a series of electrical devices for controlling the operation and safety monitoring of the air-supported membrane equipment. The anchoring system, including ground anchors and embedded parts, is used to fix the air-supported membrane equipment to the ground, preventing it from being blown away or moved by the wind.

[0052] Since the air-supported membrane equipment uses membrane material 11 as the main structural material, the splicing and fixing of membrane materials 11 need to have certain sealing performance, stability, and durability. First, the seams must have good sealing performance to prevent air leakage. Special sealants or sealing strips are generally used as sealing materials to ensure the stability and safety of the air-supported membrane equipment. Second, the seams need to have sufficient strength and stability to withstand various loads and stresses experienced by the air-supported membrane equipment during use. This includes natural factors such as wind load, snow load, and earthquakes, as well as human factors such as personnel activities and equipment facilities. Third, the seams should have good durability and maintainability to ensure the service life and long-term performance of the air-supported membrane equipment. The design must consider factors such as the corrosion resistance and self-cleaning properties of the materials, as well as subsequent maintenance and repair requirements. In addition, the design of the seams must also consider engineering costs and construction feasibility. While ensuring the performance of the air-supported membrane equipment, the lowest possible cost and simplest process node design should be selected to improve the cost-effectiveness and construction efficiency of the project.

[0053] In some specific embodiments, the joints between the membrane materials 11 form an arc, and multiple fixing mechanisms are evenly distributed along each arc, with each fixing mechanism connected to a spraying device 3. In this application, the spraying device 3 and the fixing mechanisms are distributed at each seam node along the seam line, as shown in the attached... Figure 2 In this design, the location of the spray device 3 is the seam node. The seam line can be understood as a long arc, and the seam nodes are multiple points along this arc. In some embodiments, a pressure plate and stainless steel bolts are provided at the seam node. Each pressure plate contacts the membrane material 11 via a rubber pad, and the stainless steel bolts penetrate the edges of the two membrane materials 11 to be connected. The two pressure plates achieve a fixed connection between the membrane materials 11. Furthermore, a waterproof membrane is provided on the outer surface of the seam node to ensure its airtightness.

[0054] In some specific embodiments, the water supply device 2 includes a water storage device and a booster pump. Since air-supported membrane devices generally have a certain height, the water supply device 2 needs to deliver water to each spraying device 3, using the booster pump to provide sufficient water pressure to meet the spraying needs of the high-altitude spraying devices 3. Furthermore, dust removal using spray also requires a certain water pressure. For example, to ensure dust removal effectiveness, high-pressure spray dust removal can be used. A high-pressure plunger pump pressurizes purified water, which is then sprayed out at high speed through a precision microporous atomizing nozzle, producing ultrafine mist particles of 5-15 μm. These ultrafine mist particles adsorb dust in the air and fall due to gravity, thus purifying the air environment.

[0055] The connection relationship between the fixing mechanism and the spraying device 3 is shown in the attached figure. Figure 3 As shown. In some specific embodiments, the fixing mechanism includes a first fixing member 51 and a second fixing member 52 that are fixedly connected to each other; at least a portion of the first fixing member 51 is fixedly connected to the inner wall of the air-supported membrane body B1; the second fixing member 52 is fixedly disposed on the portion of the first fixing member 51 located on the inner wall of the air-supported membrane body B1, and is detachably fixedly connected to the pipe 4. The fixing mechanism is used to fix the pipe 4 and the air-supported membrane body B1. The pipe 4 can be fixed by means of some fixing devices such as fixing hooks, while the fixing on the air-supported membrane body B1 is relatively cumbersome. On the one hand, it is necessary to consider the degree of fixation of the fixing mechanism on the air-supported membrane body B1, and on the other hand, it is also necessary to consider the degree of influence of the fixing mechanism on the air-supported membrane body B1.

[0056] The fixing mechanism is divided into two fixing components. The first fixing component 51 is responsible for connecting the air-supported membrane body B1, and the second fixing component 52 is responsible for fixing the connecting pipe 4. A transitional connection is achieved through these two intermediate mechanisms, reducing the impact on the air-supported membrane body B1. In some specific embodiments, the first fixing component 51 includes a connecting structure 513, a first plate structure 511 located on the inner wall of the air-supported membrane body B1, and a second plate structure 512 located on the outer wall of the air-supported membrane body B1. The second fixing component 52 is fixedly connected to the first plate structure 511. A connecting hole is provided through the air-supported membrane body B1, and the connecting structure 513 detachably connects to the first plate structure 511 and the second plate structure 512 through the connecting hole. The structure of the first fixing component 51 is shown in the attached figure. Figure 4 As shown. Connection holes are made on the air-supported membrane body B1 to achieve two fixations, minimizing damage to the air-supported membrane body B1. The first plate structure 511 and / or the second plate structure 512 can be made of aluminum pressure plates. Aluminum pressure plates are rolled materials made of aluminum sheets, undergoing multiple processing and heat treatments during manufacturing. They possess advantages such as light weight, high strength, corrosion resistance, and good thermal conductivity, meeting diverse application requirements.

[0057] Regarding the spray device 3, appropriate nozzles can be selected according to actual needs, or spraying can be achieved by opening holes in the pipe 4. In some specific embodiments, multiple holes are opened in the pipe 4, and the holes constitute the spray device 3. In some specific embodiments, the spray device 3 includes a connecting part 31 and a spray head 32, with the connecting part connecting the pipe 4 and the spray head 32; the spray head 32 is used to spray liquid in the form of a mist. The spray device 3 atomizes water into tiny droplets, increasing the amount of dust particles in the air, and relying on the adsorption effect of the water mist to settle the dust particles, thereby achieving the dust removal effect. In some specific embodiments, the spray device 3 also includes a valve assembly, which connects to the spray head and / or the connecting part, and is used to adjust the water output of the spray head. The spray device 3 can be connected to an automatic control device to automatically adjust the spray volume and water pressure according to the dust concentration and environmental parameters to maintain the cleanliness of the internal environment.

[0058] In some specific embodiments, the pipe 4 includes a main pipe 41 and multiple branch pipes 42. The main pipe 41 connects to the water supply device 2 located outside the internal space and passes through the air-supported membrane body B1. Each branch pipe 42 connects to the main pipe 41, and one branch pipe 42 is distributed at the connection point between each membrane material 11. The distribution of the pipes 4 is shown in the attached figure. Figure 1 As shown, the spray device 3 is integrated on the branch pipe 42.

If the current air velocity in the dust removal area is not higher than the preset velocity, the electrostatic dust removal equipment is started to perform electrostatic dust removal in the dust removal area, and combined with manual dust removal, the removal of corrosive dust in the dust removal area is completed.
