Upgrade overview
This energy-efficiency upgrade for an environmental-protection fan addresses applications containing dust and flammable or explosive gases, dusts or vapours. It replaces the existing equipment with a smart fan featuring an integrated explosion-proof design and intelligent control modules, helping the enterprise operate more safely and with lower carbon emissions.
For this application, Wolong combines explosion-proof permanent-magnet motors, explosion-proof impellers and an intelligent control system into an energy-saving solution. The result is a safe, efficient explosion-proof upgrade that integrates environmental protection, energy saving and safety, helping customers develop new quality productive forces.
Customer pain points
1. High energy cost: The electrical energy consumed during fan operation exceeded the expected or acceptable range, increasing energy cost.
2. Failure to meet production-safety standards: The fan had been in service for a long time, and its technical performance, safety and economic performance could no longer meet current production requirements or safety standards.
3. Poor equipment performance: Actual environmental conditions and loading differed from the original design assumptions. Oversized equipment for the load reduced fan performance and increased energy consumption.
4. Inadequate explosion protection: The exhaust gas handled by the fan contains dust, requiring specialised explosion-protection measures to keep equipment operating safely.
5. Low level of intelligence: The equipment operated at full frequency, with no scope for adjustment.
Energy-saving performance
The upgraded smart fan can switch between manual and automatic operation, has autonomous control capability, adapts to operating conditions and remains in its high-efficiency range for extended periods, substantially reducing energy consumption. Under the same operating conditions, energy savings reached 47% compared with the original fan equipment. The fan’s integrated explosion-proof design also safeguards safe production.
Explosion-proof fan applications
Explosion-proof fans are used primarily in environments containing flammable or explosive gases, dusts or vapours. They support air circulation, reduce explosion risk and protect people and equipment.
1. Coal mining and mining: In underground coal mines, drifts and tunnels, explosion-proof fans provide ventilation, reduce methane accumulation and explosion risk, and help keep working environments safe.
2. Oil and gas: In oil and gas extraction, processing, separation and storage, explosion-proof fans maintain air circulation and prevent accumulation of flammable or explosive gases.
3. Chemical industry: Chemical production and storage may generate toxic, flammable or explosive gases or dusts. Explosion-proof fans provide ventilation to help ensure production safety.
4. Pharmaceutical and food industries: Specific areas such as solvent-recovery zones and dust-treatment areas may also require explosion-proof fans to safeguard air quality and safety.
5. Special industrial environments: In dust-explosion hazard zones, spray booths and similar sites, explosion-proof fans maintain air circulation and help prevent dust or flammable-gas accumulation.
