[0030] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this disclosure.

[0031] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0032] like Figure 1 and Figure 2 As shown, a ventilation and dust removal device for cleanroom construction according to this application includes multiple components such as a frame 1, a filter 2, an electrostatic adsorption module 3, a desiccant layer 4, and a connector 5.

[0033] The frame 1 of the device provides support and fixation for the overall structure. The frame 1 is the basic framework of the entire device, made of high-strength metal material, designed to withstand the weight of all embedded components, and to ensure the stability and reliability of the device structure throughout operation.

[0034] Installed inside rack 1 is filter 2, which is used to filter larger particles in the incoming air, such as dust and some large debris. This filter 2 adopts a high-efficiency multi-layer filter structure, which can trap larger particles and allow clean, pre-filtered airflow to pass through into the processing area of ​​subsequent components, thereby improving purification efficiency and reducing the pressure on subsequent purification components.

[0035] Located at the rear end of filter 2 is electrostatic adsorption module 3, a crucial component of the device, specifically designed to remove fine particulate pollutants. It utilizes the principle of electrostatic field to generate static charges that capture extremely fine particles suspended in the airflow, effectively aggregating and settling them onto a dielectric surface, playing a central role in air purification.

[0036] A desiccant layer 4 is provided before or after the electrostatic adsorption module 3. This layer uses a special desiccant with strong hygroscopic properties as its material base, which can absorb and lock in moisture carried by the external environment or air that has not been dehumidified by upstream components for a long time. This ensures that the humidity in the passing air is maintained at a relatively low level, protecting the electrostatic adsorption part from performance degradation or failure caused by excessive moisture, and further ensuring the stability and safety of air quality.

[0037] The aforementioned components are joined together into a single structure via a series of connectors 5. The connectors mainly include bolts of different types and a number of fixed plates. These hardware components are used to tightly assemble the entire machine and prevent air leakage at any point, ensuring that each processing step can be carried out smoothly in a strictly closed state and that the various components maintain perfect cooperation.

[0038] To address the practical problems of weakened electrostatic attraction and impaired insulation performance of electrostatic adsorption units caused by high humidity environments, this solution employs a four-stage desiccant layer to control the amount of moisture in the airflow. This pre-dehumidification ensures that the humidity of the air entering the adsorption zone remains within a safe range; simultaneously, it reduces the interference of water molecules on the formation of charged surfaces, effectively improving the operational quality and lifespan of the entire purification system. Ultimately, this innovative design significantly optimizes and resolves the adverse consequences of humid conditions, resulting in a purer, dust-free, reliable, and healthy indoor environment during cleanroom operations.

[0039] Continue to refer to Figure 2 In one embodiment, the filter 2 of the ventilation and dust removal device for cleanroom construction according to this application adopts a multi-layer composite filter structure, including a coarse filter 6, a medium-efficiency filter 7, and a high-efficiency filter 8. This design can more effectively intercept larger dust particles while preventing fine dust from entering the electrostatic adsorption module 3, ensuring that the electrostatic adsorption module 3 operates in a relatively low-humidity working environment, thereby effectively extending its service life. Through this multi-layer filtration structure design, the overall filtration efficiency of the device can be significantly improved, and the air quality requirements during cleanroom construction can be maintained. Specifically, the composite filter consists of three layers: the outermost coarse filter 6 is used to initially capture large dust particles and debris; the second layer is the medium-efficiency filter 7, which is used to further intercept particles between coarse and fine; and the innermost layer is the high-efficiency filter 8, which is specifically designed to provide a final protective barrier for microparticles and submicron-sized particles.

[0040] For example, in a specific application scenario, the aforementioned composite filter structure is installed at the front end of the ventilation duct, directly behind the air inlet. The coarse filter 6 directly covers the entire air inlet, acting as the initial physical barrier. The subsequent medium-efficiency filter 7 is fixedly positioned in an appropriate area immediately downstream of the coarse filter 6, forming a secondary barrier. The high-efficiency filter 8 is placed after both of them, serving as the final treatment component near or integrated into front of the static electroadsorption unit inlet, forming a continuous and rigorous three-stage filtration barrier system.

[0041] In one embodiment, the electrostatic adsorption module 3 of the ventilation and dust removal device in the cleanroom construction process of this application is provided with multiple ionization plates 9 and collection plates 10, forming several sets of electrostatic fields. Each ionization plate 9 carries a negative high voltage to attract positively charged particles and fix them on the collection plate 10, thereby achieving efficient capture of airborne particles. To ensure the long-term stable operation of the device, a periodic cleaning mechanism 11 is also provided inside the module to prevent the electrostatic adsorption effect from being reduced due to excessive moisture accumulation, ensuring the long-lasting and reliable effect of electrostatic adsorption.

[0042] To further improve air purification efficiency and reduce cleaning frequency, ionization plates 9 are installed on one side of the ventilation airflow channel to maximize the contact area with airborne particles. Simultaneously, each ionization plate 9 is paired with a collection plate 10, and the distance between them is optimized to ensure that the electrostatic field covers the entire airflow cross-section, ensuring efficient dust and impurity capture. An appropriate gap is maintained between the collection plate 10 and the ionization plate 9 to provide sufficiently strong electrostatic attraction without interfering with airflow. These components are compactly integrated into the static adsorption module, maintaining both high efficiency and space-saving design. Furthermore, for convenient maintenance, a periodic cleaning mechanism 11 is integrated into one end of the electrostatic adsorption module 3, facilitating easy access to cleaning tools or replacement of consumables. This design simplifies daily maintenance procedures and reduces the technical requirements on users.

[0043] For example, the ionization plate 9 and the collection plate 10 can be made of metal and coated with a protective layer with good corrosion resistance. These plates can be installed horizontally or vertically in the ventilation duct, depending on the installation conditions and the required airflow. The periodic cleaning mechanism 11 includes an automated cleaning brush system that can move to various locations at preset time intervals to remove accumulated dirt and ensure long-term performance stability. Meanwhile, all electrical connections are designed to be waterproof and interference-resistant to ensure safe and stable operation under high-voltage conditions.

[0044] In one embodiment, the desiccant layer 4 of the ventilation and dust removal device in the cleanroom construction process of this application is filled with a certain amount of calcium chloride 12, which serves as a highly hygroscopic material. The desiccant layer 4 is positioned at a specific location inside the ventilation and dust removal device to ensure that the airflow can fully contact and absorb moisture from the air. The desiccant layer 4 not only has the characteristics of rapid and large-capacity absorption of moisture from the air, but also possesses self-desorption and regeneration capabilities, automatically removing absorbed moisture and restoring its adsorption capacity under certain conditions. This characteristic enables the system to maintain stable operation under varying humidity conditions. Simultaneously, the effective placement of the desiccant layer 4 further enhances the insulation performance and electrostatic efficiency of the static adsorption module and reduces surface condensation.

[0045] Specifically, this device can be installed in the middle or end of the airflow path to effectively dry the air, ensuring that the exhaust air meets high cleanliness standards. For example, in one embodiment, the desiccant layer 4 can be installed on the inner wall of the air duct using fasteners or slots, ensuring its secure fixation and preventing displacement. Calcium chloride 12 is uniformly filled in a breathable but dust-proof mesh bag or container for easy maintenance or replacement. Furthermore, by controlling the airflow speed and temperature conditions, the calcium chloride 12 can efficiently complete the moisture absorption and desorption process, maintaining the long-term stable dehumidification and purification effect of the equipment.

[0046] In one embodiment, the connector 5 of the ventilation and dust removal device in the cleanroom construction process of this application is made of high-strength stainless steel and protected by an anti-corrosion coating. The connector 5 is located at a critical interface of the entire device and is mainly used to securely connect various modules and components together. The design of the connector 5 fully considers the requirements of the operating environment, maintaining stable performance even in high-temperature and humid environments. The stainless steel material used in the connector 5 has high strength and tensile properties, effectively resisting the effects of external pressure and its own weight.

[0047] To enhance corrosion resistance, the surface of connector 5 is treated with a special anti-corrosion coating technology. This process ensures that even long-term exposure to humid and hot environments will not cause deformation or corrosion, guaranteeing that the physical and mechanical properties of connector 5 are unaffected by environmental factors. Specifically, a uniform and dense anti-corrosion film is formed through a combination of sandblasting and electroplating techniques, enhancing the barrier effect against corrosive media.

[0048] In addition, to eliminate potential assembly errors and further ensure the entire assembly is airtight, a fixing clamp 13 is installed next to the connector 5. This device is mainly responsible for applying additional locking torque to important nodes during assembly. The fixing clamp 13 contains a series of spring elements and adjusting nuts. When the torque needs to be adjusted, the corresponding parts can be rotated. During installation, the connector 5 is first inserted into the predetermined position, and then the fixing clamp 13 is fastened. The fastening screws are manually tightened until the required torque value is reached, thus ensuring that the connector 5 fits tightly and will not loosen or leak due to vibration or temperature changes.

[0049] For example, in a typical engineering application scenario, connector 5 is installed between the end of the duct and the HEPA filter 2. In this process, the high-strength stainless steel connector 5 is first connected to the flanges on both sides using screws; then, after positioning and adjusting, a special tool is used to accurately place the fixing clip 13 in the designated position, and sufficient clamping force is applied to achieve a sealing effect. This effectively ensures pressure balance and purification quality within the airflow channel.

[0050] In one embodiment, the volume ratio of the desiccant layer 4 to the internal space of the frame 1 in the ventilation and dust removal device of the cleanroom construction process of this application is greater than or equal to 1:5. This ratio is chosen to optimize the residence time of air in the desiccant layer 4, ensuring sufficient drying and effective humidity control. This feature solves the problem of electrostatic adsorption caused by high humidity and enhances the safety and reliability of the entire ventilation and dust removal device.

[0051] Specifically, the desiccant layer 4 is located in a specific area within the frame 1 to process the pre-filtered airflow. The size and structure of the frame 1 determine the specific layout of the installation location. Typically, the desiccant layer 4 is located after the fan and before the dust removal module. This arrangement allows the airflow to remain in this location for a longer period, resulting in optimal dehumidification. Furthermore, the desiccant material can be flexibly selected according to different applications, such as highly efficient moisture-absorbing materials like silica gel and activated alumina. This selection not only considers the effective adsorption of moisture from the air but also the ease of replacement and maintenance.

[0052] To meet the aforementioned requirements, in practical operation, a larger desiccant container can be used, or the usable volume of rack 1 can be shortened, thereby increasing the proportion of the total space occupied by the desiccant layer 4. For example, the installation space for the desiccant can be expanded by adding multi-layered desiccant assemblies or arranging certain auxiliary components more compactly. These measures help maintain a longer path and sufficient residence time for air as it passes through the desiccant layer 4, ensuring that effective dehumidification continues.

[0053] Continue to refer to Figure 2 In one embodiment, a humidity sensor 14 is added between the electrostatic adsorption module 3 and the desiccant layer 4 of the ventilation and dust removal device in the cleanroom construction process of this application. The electrostatic adsorption module 3 is mainly responsible for removing particulate matter from the air, while the desiccant layer 4 is used to reduce relative humidity and prevent problems caused by excessive humidity during electrostatic adsorption. When the device is working, the electrostatic adsorption module 3 may be affected by changes in ambient humidity, especially in high humidity environments, which may lead to a decrease in adsorption performance. Therefore, installing a humidity sensor 14 between the electrostatic adsorption module 3 and the desiccant layer 4 can monitor changes in the nearby relative humidity.

[0054] The humidity sensor controller 14 consists of components such as a humidity sensing element, a processing circuit, and a heating element 15. The controller is installed in a pipe or channel between the output end of the static adsorption module and the input end of the desiccant layer 4. Specifically, the humidity sensor controller 14 is securely installed using a fixing clip 13 or other suitable fasteners to ensure detection accuracy and response speed. Once the controller detects that the relative humidity in the nearby air is too high, it triggers a preset threshold to activate the heating element 15. The heating element 15 is then tightly attached to the desiccant layer 4 and is evenly distributed on its surface or embedded within it.

[0055] For example, the heating element 15 is a resistive heating element, which can quickly reach the operating temperature within the set temperature range after the controller issues a command, thereby heating the desiccant layer 4 and causing the adsorbed water vapor to be released from the drying material and carried away by the extraction system. This design allows the device to restore the humidity conditions required for normal operation in a short time, preventing potential negative impacts on the static adsorption effect.

[0056] In one embodiment, the surface of the electrostatic adsorption module 3 of the ventilation and dust removal device in the cleanroom construction process of this application is coated with a hydrophobic and oil-resistant coating 16. The hydrophobic and oil-resistant coating 16 can be, for example, a fluorocarbon resin coating, a siloxane coating, a nano-silica coating, or a fluoropolymer coating. This special coating effectively inhibits moisture deposition on the surface of the electrostatic adsorption module 3 even in humid environments. Therefore, in high-humidity environments, there is no problem of decreased insulation performance due to moisture accumulation. Simultaneously, this special hydrophobic and oil-resistant coating significantly reduces the probability of contaminants adhering to the electrostatic adsorption module 3. Since contaminant particles are less likely to adhere, this not only facilitates regular cleaning and maintenance but also helps ensure the equipment remains in good operating condition for a long time. Through improvements to this technical feature, the ability of the ventilation and dust removal device to adapt to complex construction environments and the reliability of the equipment are further enhanced.

[0057] In a specific example, the electrostatic adsorption module 3 adopts a fully enclosed structure, with the entire outer surface coated with the hydrophobic and oil-resistant coating. This coating can be uniformly applied across the entire outer surface of the electrostatic adsorption module 3 using a spraying process, ensuring consistent coating thickness. Specifically, during manufacturing, a coating solution with ideal hydrophobic and oil-resistant properties is first prepared; then, the electrostatic adsorption module 3 is placed in a dedicated coating chamber, and a precisely controlled spray gun is used for omnidirectional spraying until a uniform coating is achieved. For example, a material containing fluorocarbon segment polymers can be selected as one of the main components to formulate the solution, providing the required hydrophobicity and oil resistance. Finally, the component with the wet coating is cured under suitable temperature conditions to ultimately form a robust and durable hydrophobic and oil-resistant coating.

[0058] In one embodiment, the desiccant layer 4 of the ventilation and dust removal device in the cleanroom construction process of this application uses modified zeolite molecular sieves as the main material. This desiccant layer 4 is positioned along the critical path of the device to ensure that the passing air can fully contact the material and exert its adsorption effect. Modified zeolite molecular sieves, due to their unique microstructure and chemical properties, possess excellent adsorption performance and high selectivity, particularly excelling in treating trace small molecules in the air. These small molecules include, but are not limited to, carbon dioxide. Through the effective use of this desiccant layer 4, not only can the humidity of the cleanroom air be effectively controlled, but other pollutants can also be removed, improving indoor air quality.

[0059] Specifically, the modified zeolite molecular sieve is prepared from special zeolite materials, possessing numerous surface active sites and high porosity, thus exhibiting strong adsorption capacity. Furthermore, the molecular sieve itself contains special functional groups, significantly enhancing its selectivity for gases. To better utilize the modified zeolite molecular sieve, it is positioned inside the device after the air inlet and before the high-efficiency filter unit, ensuring further purification of the air flowing through this layer. Through this configuration, the desiccant layer 4 can efficiently adsorb moisture and other harmful gases during air passage, ensuring air quality and making the cleanroom air fresher and more pleasant.

[0060] In one embodiment, a plate-shaped modified zeolite molecular sieve of suitable size can be selected as the desiccant layer 4 and fixed in a predetermined position within the device frame. This position is typically located after the pre-filter 2 and before the HEPA filter 2 to form an effective airflow path. The fixing method can be clips, screws, or a dedicated bracket to ensure structural stability and reliability. When air enters the device, after primary filtration by the pre-filter 2, it directly contacts the surface of the desiccant layer 4. Excess moisture and fine particulate matter are removed through the physical adsorption of the molecular sieve, ultimately achieving the desired purification effect.

[0061] In one embodiment, such as Figure 3 As shown, to better prevent short circuit hazards caused by high humidity on the surface of the electrostatic adsorption module 3, an independent grounding terminal 17 is added to the frame 1 and connected to the building's foundation metal grid via a wire. This independent grounding terminal 17, as an additional safety measure, not only provides reliable electrical safety protection but also effectively enhances the system's stability and anti-interference performance. Anti-static measures are crucial during cleanroom construction, especially in high-humidity environments; therefore, this design has significant practical value.

[0062] Specifically, a suitable location for installing the independent grounding terminal 17 can be determined first, for example, choosing a location away from major electrical components but close to the edge. Subsequently, this terminal is connected to the basic metal mesh network inside the building using high-quality wires to form a low-resistance grounding path, ensuring that the entire unit can still operate stably when encountering humidity changes.

[0063] In yet another embodiment, such as Figure 4As shown, the connecting parts of the ventilation and dust removal device in the cleanroom construction process of this application employ a self-locking anti-loosening design 18 at the nut position. This design ensures that the connection will not easily come loose even under long-term vibration. The self-locking anti-loosening structure, through specific design and material selection, effectively prevents relative movement between the nut and the screw in a vibrating environment. For example, in some common application scenarios, such as the vibration environment of a construction site, this design has significant advantages. Furthermore, a sealing strip 19 is installed at the joint to achieve waterproof and dustproof sealing. The sealing strip 19 is typically made of elastic rubber or other high-performance sealing materials, possessing excellent resilience and weather resistance, ensuring a tight fit between components without noticeable gaps, thereby ensuring that the external environment does not affect the internal static electricity level. The combined effect of these designs places the entire ventilation and dust removal system in a highly stable working environment, avoiding interference from external conditions.

[0064] Specifically, in implementation, the self-locking anti-loosening design 18 can be achieved using nylon inserts, star-shaped washers, or other similar techniques. Connectors 5 are installed at key locations in the ventilation system requiring fixation and sealing, while sealing strips 19 wrap around the joints of these key locations, forming an effective sealing band. For example, during assembly, first ensure all connectors 5 are tightened to the specified pre-tightening torque, then carefully check the position of each sealing strip 19 to ensure a good sealing effect and guarantee the overall stability of the system.

[0065] In one embodiment, an adjustable louvered air vent 20 is installed at the side opening of the frame 1 in a ventilation and dust removal device for cleanroom construction according to this application. By adjusting the air intake angle and flow rate, this design ensures that the airflow, after being filtered through fresh, dry air, can smoothly reach the target area, and that it has undergone rigorous dust and moisture removal treatment in the process. The adjustable louvered air vent 20 can not only adapt to different application requirements, but also avoid the adverse effects of high humidity environments on aseptic operations. This setup optimizes the indoor working environment and significantly improves work efficiency and quality.

[0066] Specifically, the adjustable louvered air vent 20 is installed at the side opening of the frame 1, allowing adjustment of the blade opening angle and the overall flow parameters of the device according to actual needs. The blades have a wide adjustment range to adapt to different air intake requirements. The adjustable louvered air vent 20 is robust and durable, possessing high airtightness and corrosion resistance, enabling stable operation for extended periods in various complex environments. Furthermore, by precisely controlling the airflow direction and speed, this device ensures that air is adequately prepared before entering the purification system, thereby achieving ideal working environment indicators.

[0067] For example, the angle of the louver blades can be changed using a drive mechanism such as a stepper motor or a manual knob. The stepper motor receives signals from the control system and precisely adjusts the opening and closing degree of the blades, thereby controlling the direction and flow rate of airflow. This technical solution improves the operational flexibility of the equipment and facilitates automated adjustments based on real-time monitoring data. Furthermore, environmental monitoring sensors can be integrated to provide real-time feedback on air quality and humidity parameters, further optimizing the equipment's operating status.

[0068] In actual operation, when this device is in use, its components work closely together to ensure that the air quality in the cleanroom always meets strict cleanliness standards. First, air enters the ventilation and dust removal device from the external environment. The frame 1, as the supporting and fixing framework of the entire system, plays a fundamental role in stabilizing each functional module, ensuring the reliability and safety of the overall structure of the device. Then, the airflow enters the device and passes through filter 2. Filter 2 plays a crucial initial barrier role here, capturing larger particulate matter and impurities in the air through a fine fiber mesh or other media materials, thus initially purifying the air. After the initial filtration, the airflow, containing fewer large dust particles but still damp and possibly containing fine dust particles, continues to flow downwards and reaches the electrostatic adsorption module 3. This module uses high voltage to generate corona discharge, forming a strong and stable electrostatic field inside. This causes small particles in the air passing through to become charged and collide with the positive and negative plates, thus being captured and removed.

[0069] To ensure the longevity of the electrostatic adsorption effect and prevent damage to the electrical insulation performance of the module itself, the desiccant layer 4 plays an indispensable and important auxiliary role in the entire process. Since the presence of moisture not only poses a risk of condensation but may also weaken the electrostatic force and even shorten the module's lifespan, the desiccant layer 4, located after filter 2 or before or after the electrostatic adsorption module 3, utilizes its strong moisture absorption capacity to continuously lock in excess water molecules carried in the airflow and convert them into a solid state, thereby maintaining a low air humidity and preventing the aforementioned adverse conditions.

[0070] The specific embodiments described above further illustrate the purpose, technical solutions, and beneficial effects of the embodiments of this disclosure. It should be understood that the above descriptions are merely specific embodiments of the embodiments of this disclosure and are not intended to limit the scope of protection of the embodiments of this disclosure.
