Demand for Industrial Dust Collectors in Various Processes of Battery Manufacturing Plants and HIPOW Solutions
Battery manufacturing is a highly precise industry with extremely stringent requirements for the production environment. From electrode preparation to cell assembly, nearly every process generates different types of dust, smoke, and exhaust gases. These pollutants not only endanger employee health and affect product yield but also pose serious explosion risks. Therefore, efficient and reliable industrial dust collection and fume purification systems are indispensable "lifeline" equipment for modern battery production lines. As an industry leader, HIPOW's explosion-proof dust collection solutions have been successfully applied in global top-tier battery manufacturing plants, including BYD and CATL.
I. Dust Collection and Purification Requirements for Core Processes in Battery Manufacturing
The battery production process is complex, with main pollution sources and dust collector requirements as follows:
1. Electrode Preparation Process (Mixing, Coating, Calendering, Slitting)
◦ Pollution Sources: Dust from positive and negative active materials (such as lithium cobalt oxide, lithium iron phosphate, graphite, carbon black, etc.). This type of dust has fine particle size, large specific surface area, and is highly flammable and explosive.
◦ Requirements: Efficient source capture and centralized dust collection are needed during feeding, mixing, and transportation to prevent dust dispersion. HIPOW's explosion-proof centralized dust collection system ensures dust concentration in this area remains far below the lower explosion limit.
2. Electrode Sheet Process (Die-Cutting, Laser Cutting)
◦ Pollution Sources: Metal debris from cutting, coating dust, and high-temperature fumes and aerosols generated by laser cutting.
◦ Requirements: High-negative-pressure, high-temperature-resistant fume purifiers are needed to instantly capture fumes at the generation point, preventing them from condensing and adhering to equipment or cell surfaces, which could affect insulation and safety. HIPOW's laser fume purifiers are specifically designed for this purpose.
3. Cell Assembly Process (Winding/Stacking, Welding)
◦ Pollution Sources: Metal oxide fumes (containing nickel, aluminum, copper, etc.) generated by ultrasonic welding and laser welding. These sub-micron fumes are toxic and may cause short circuits.
◦ Requirements: Point-to-point fume purification equipment with flexible extraction arms or workbenches is required to ensure clean welding stations, protect operators' respiratory health, and maintain internal cleanliness of the cells.
4. Electrolyte Filling and Formation Process
◦ Pollution Sources: Organic exhaust gases (VOCs) volatilized from the electrolyte. Electrolyte solvents are flammable.
◦ Requirements: Although primarily treating VOCs, the connected ventilation systems must have explosion-proof and fire-resistant functions to prevent any spark risks. HIPOW can provide integrated explosion-proof ventilation solutions.
II. Core Importance of Dust Collection and Purification Systems in Battery Plants
1. Safety and Explosion Prevention—The Primary Lifeline: Battery material dust (especially anode graphite) has an extremely low minimum ignition energy (MIE). When mixed with air to a certain concentration, it can cause severe explosions upon encountering static electricity, open flames, or high temperatures. Professional industrial dust collectors are the first and most critical line of defense against dust explosions.
2. Ensuring Product Yield and Consistency: Micro-dust adhering to electrode sheets or cell surfaces can lead to internal short circuits, high self-discharge rates, capacity degradation, and other issues. A clean production environment is a fundamental prerequisite for manufacturing high-performance, high-safety, and long-life batteries.
3. Fulfilling Environmental and Occupational Health Responsibilities: Effectively collecting harmful dust and fumes during production ensures compliance with emission standards and provides a safe working environment for employees, meeting national standards such as "Occupational Exposure Limits for Hazardous Factors in the Workplace" and ISO 14001.
4. Protecting Precision Equipment and Reducing Maintenance Costs: Preventing dust from infiltrating expensive laser equipment, optical inspection systems, robot joints, etc., reduces equipment failures and extends service life.
III. Explosion-Proof Design and Core Requirements for Dust Collectors in the Battery Industry
Given the特殊性 of battery production, dust collectors must adhere to strict design specifications:
1. Explosion-Proof Design and Certification: The dust collector body must comply with ATEX (European standard) or GB 3836 (Chinese national standard) explosion-proof standards, typically requiring Zone 21/22 explosion-proof ratings. The body adopts explosion-proof structural design to withstand internal explosion pressure without permanent deformation.
2. Explosion Venting and Isolation Devices: Must be equipped with explosion venting panels to safely direct pressure outdoors in case of an explosion. Inlet and outlet vents should have explosion isolation valves to prevent flames and pressure from propagating to the workshop pipeline network.
3. Static Electricity and Grounding Control: Filter materials should use anti-static materials (such as anti-static coated filter cartridges). All components (filter cartridges, hoppers, ducts) must be equipotentially bonded and reliably grounded, ensuring static resistance is less than 100Ω to彻底 eliminate static spark risks.
4. Monitoring and Interlock Protection: Integrated temperature sensors, differential pressure sensors, spark detection, and extinguishing systems. Upon detecting abnormal temperature rises or sparks, alarms are triggered immediately, and sprinkler extinguishing systems are activated, while safety interlock shutdowns with production line equipment are initiated.
5. Fire Protection Integration: Can integrate fire sprinkler or inert gas (such as nitrogen) injection systems for active fire suppression.
6. High-Efficiency Filtration and Leakage Prevention: Uses high-efficiency coated PTFE filter cartridges with filtration efficiency exceeding 99.99%, ensuring ultra-fine dust does not escape. Sealed structures prevent dust leakage during non-operational states.
IV. HIPOW: Explosion-Proof Dust Collection Expert Serving Global Top Battery Manufacturers
HIPOW deeply understands the stringent demands of the battery manufacturing industry. Its products and solutions have successfully served multiple production bases of BYD and CATL, becoming a trusted environmental safety partner in their supply chains.
• At BYD's Plant: HIPOW provided large-scale centralized explosion-proof dust collection systems for its electrode workshop, covering the entire process from raw material feeding to electrode sheet slitting. The system adopts modular explosion-proof design, equipped with complete spark detection and explosion venting isolation measures, ensuring production safety in this high-risk area while achieving low-energy operation through constant differential pressure control.
• At CATL's Plant: For its highly automated die-cutting and welding stations, HIPOW deployed dozens of high-negative-pressure explosion-proof laser fume purifiers and welding fume purification workbenches. These devices have CE/ATEX explosion-proof certifications, and precise source capture effectively ensures cell cleanliness, providing strong support for the high consistency of CATL's products.
The core advantage of HIPOW's products lies in the fact that they are not merely dust collection equipment but a systematic solution deeply integrated with battery processes, centered on safety and explosion prevention, while balancing energy efficiency and intelligent management. From risk assessment and solution design to installation, commissioning, and ongoing services, HIPOW builds a solid safety and quality barrier for battery manufacturers.
In summary, in the era of large-scale battery manufacturing moving toward TWh, industrial dust collection and fume purification systems have evolved from auxiliary equipment to critical infrastructure for core safety assurance and quality control. Choosing a partner like HIPOW, with mature explosion-proof technology, profound industry experience, and validation from leading customers, is an inevitable choice for battery manufacturers building modern, intelligent, and safe factories.
