Case Study of Xi'an Runlai RL-E200Ex Explosion-Proof Hydrogen Analysis System in Lithium Energy Industry

I. Industry Background

During the production of new energy lithium-ion batteries, processes such as electrolytic hydrogen production, cell formation, aging testing, and energy storage PACKing continuously generate hydrogen gas. Hydrogen has a wide explosion limit and spreads quickly, making it a high-risk hazard. Additionally, lithium battery workshops are characterized by dust, electrolyte vapor, and significant temperature and humidity fluctuations. Conventional hydrogen detection equipment often suffers from insufficient explosion-proof ratings, poor interference resistance, inaccurate data, and frequent false alarms or missed detections. These issues not only affect production yield but also pose serious safety risks, failing to meet safety inspection requirements and intelligent production standards.

II. Product Introduction (RL-E200Ex Explosion-Proof Hydrogen Analysis System)

Xi'an Runlai's RL-E200Ex is an explosion-proof online hydrogen analysis system specifically designed for flammable and explosive environments such as lithium batteries and hydrogen production. It is suitable for hydrogen monitoring throughout the entire lithium battery production process, with the following core advantages:

• High-level Explosion Protection, Compliance: Meets ExdⅡCT6 high explosion-proof standards, eliminating the risk of electric sparks and fully complying with lithium battery workshop explosion-proof requirements, successfully passing safety inspections.
• Stable and Highly Interference-resistant: Utilizes high-precision thermal conductivity sensors, supports full-range hydrogen detection, and is equipped with a constant temperature and pressure system, effectively resisting interference from workshop dust, electrolyte vapor, temperature and humidity, ensuring fast data acquisition and response.
• Complete Pretreatment, Strong Adaptability: Comes with multi-stage dust, water, and oil removal pretreatment, eliminating the need for additional equipment modifications, and can be directly installed and used at multiple points such as hydrogen production stations, battery formation workshops, and energy storage compartments.
• Intelligent Linkage, Easy Maintenance: Supports 4-20mA and RS485 data transmission, seamlessly integrating with factory DCS and MES control systems for real-time monitoring, audible and visual alarms for exceeding limits, and interlocking ventilation shutdowns; includes built-in data storage and traceability features to meet the needs of digital and intelligent factory management.
