The "heart" of lithium battery production contains combustible dust such as graphite and electrode materials. While these materials provide the energy to the battery, they also pose significant safety risks. When the dust mixes with air and reaches the explosive limit, even a small amount of static electricity or a spark can trigger serious consequences. How do we define safety red lines and keep risks within safe limits? Dust explosion-proof zones (zones 20, 21, and 22) are internationally recognized safety standards. A compliant and professional explosion-proof dust collector is the final guardian of this red line.
Dust explosion prevention zones assign clear risk labels to different areas based on the frequency and concentration of dust. This is the starting point for all safety protection measures.
Zone 20 (High-Risk Zone): Areas where combustible dust clouds are continuously or persistently present during normal operation.
▶ Typical Scenarios: Inside grinding mills, inside powder silos.
Zone 21 (Medium-Risk Zone): Areas where combustible dust clouds may occasionally appear during normal operation.
▶ Typical Scenarios: Near feeding ports, conveyor pipe interfaces, and dust collector unloading points.
Zone 22 (Low-Risk Zone): Areas where dust clouds are unlikely to appear during normal operation, and may only exist briefly under abnormal circumstances.
▶ Typical Scenarios: Corners of the workshop far from dust sources, and the external perimeter of equipment.
Moland’s View: Regardless of the risk level, as long as combustible dust is present, explosion-proof equipment with the corresponding protection level must be installed in accordance with safety standards such as <GB 15577>. This is not only a mandatory compliance requirement but also the bottom line of responsibility for safe production by enterprises.
Ordinary dust collectors are essentially "naked" in the face of explosion-proof zones. A professional explosion-proof dust collector provides enterprises with comprehensive safety assurance through systematic design:
Precise matching, explosion-proof at the source: zones 20/21/22 have different risk characteristics. Some measures can be used to eliminate the ignition source at its root. These measures include electrical components, monitoring instruments, and control measures of corresponding explosion-proof levels.
Strict concentration control, eliminating conditions: By employing techniques such as high-efficiency filtration and pre-coating passivation, we continuously control the concentration of environmental dust to below the explosion limit. This fundamentally eliminates the conditions for an explosion to occur.
Compliance guarantee, stable production: Meeting national mandatory standards and safety and environmental assessment requirements is a "passport" for smooth production. Its high reliability further reduces unplanned downtime and ensures efficient and continuous production.
Cost Reduction and Efficiency Improvement, Multiple Benefits in One Go: While eliminating safety accidents, it effectively recovers valuable raw materials, reduces equipment wear, and achieves a triple improvement in "safety, environmental protection, and efficiency."
Understanding the key to dust control in the lithium battery industry, Moland has dedicated itself to creating a professional explosion-proof dust removal system, providing comprehensive protection for your safe production.
