Industrial workshops utilize various metal forming equipment, with cold forging machines being prominent for high-tonnage press-fitting and shaping of components in hardware, shipbuilding, aerospace, and related sectors. Similar to cold heading processes, cold forging operations generate significant volumes of oil mist. This pervasive mist permeates the workspace, posing direct and indirect health hazards to personnel.
Amidst stringent national environmental regulations, electrostatic oil mist purifiers have emerged as particularly effective solutions for capturing emissions from cold forging machines. These units employ a multi-stage filtration process: initially intercepting large oil droplets and dust particles, followed by charging the finer mist particles via ionization. The charged particles are then captured by positively charged collector plates, ultimately releasing harmless, purified air.
The specific purification process involves two key stages:
1. Pre-Filtration & Gross Particle Capture: Contaminated air laden with oil mist enters the purifier through the inlet and passes through a pre-filter. This stage separates larger oil mist droplets and dust particles, which coalesce and are collected in a dedicated sump.
2. Ionization & Electrostatic Collection: Air containing residual fine oil mist then flows into an ionization section. Here, the particles pass through a high-voltage ion field, acquiring a strong negative charge. This charged aerosol subsequently enters the electrostatic collection chamber. Governed by electrostatic forces, the negatively charged particles are attracted to and captured by positively charged collector plates. The purified air is then exhausted by a blower.
Industrial-grade electrostatic oil mist purifiers for cold forging equipment offer selectable air handling capacities, typically ranging from 600 m³/h to 6000 m³/h per unit. Constructed with stainless steel housings and core filter elements, these systems deliver stable performance. They incorporate fire and explosion-proof safety features and achieve purification efficiencies exceeding 95%.
This technology effectively safeguards worker health by eliminating harmful oil mist exposure within industrial workshops. Furthermore, it aligns with national environmental protection mandates, providing a reliable and efficient solution manufactured by specialized suppliers to meet rigorous industrial demands.
