Explosion-Proof Industrial Dust Collectors at Hongqi Automobile's Lithium Battery Factory

Application Case of Explosion-Proof Industrial Dust Collectors at Hongqi Automobile's Lithium Battery Factory

一、项目背景与挑战

Hongqi Automobile, a representative of high-end automobile manufacturing in China, has been consistently advancing in the field of new energy vehicles in recent years. Its lithium battery factory undertakes the production task of core power batteries. The lithium battery production environment requires extremely high standards of cleanliness and safety. Especially in processes such as electrode preparation, assembly, and electrolyte filling, dust and metal debris can cause risks of short circuits, combustion, or even explosion. Traditional cleaning equipment cannot meet explosion-proof requirements and may generate static sparks, becoming a hidden danger to safe production.

二、防爆工业吸尘器的技术特点与选型依据

The explosion-proof industrial dust collector ultimately selected by the Hongqi lithium battery factory possesses the following core technical characteristics:

The equipment has passed ATEX or national standard GB3836 explosion-proof certification. The motor, switches, and filtration system all adopt explosion-proof structures to avoid electrical sparks and high-temperature surfaces igniting explosive atmospheres.

The dust collector is equipped with a complete static electricity dissipation device: anti-static hoses, conductive wheels, and grounding chains, ensuring timely discharge of static charges during dust transport.

Utilizes HEPA + activated carbon multi-stage filtration, achieving 99.97% filtration efficiency for particles above 0.3μm, and can adsorb electrolyte volatile gases to maintain environmental cleanliness.

Components contacting dust are made of stainless steel or anti-static engineering plastics. The equipment has high overall sealing to prevent dust leakage.

Equipped with functions such as differential pressure monitoring, full bin alarm, and motor overload protection, supporting remote monitoring and data recording.

The selection criteria included: matching explosion-proof rating (suitable for Zone 22/21 areas), adapting air volume and negative pressure parameters to production line needs, material compatibility (resistant to electrolyte corrosion), and compliance with the ISO 50001 energy efficiency standard.
