Advanced Electrostatic Painting Line With Oil Curtain Circulation Purification System For Engineering Machinery

Equipment Description:

When the mobile oil curtain spray booth starts working, fresh air is sucked into the spray painting operation area from the front of the spray booth. When spraying paint, the airflow evenly surrounds the workpiece, so that the oversprayed paint mist will not splash, and the spray booth forms a negative pressure state to ensure that the oversprayed paint mist will not fly out of the spray booth. The oversprayed paint mist is sucked into the oil belly paint mist purifier under the action of negative pressure, first intercepted by the second flow oil film, and a small amount of paint mist is separated by the oil separator to meet the national standard emission requirements. The oil curtain spray booth can meet the requirements of temperature, humidity, light intensity, air cleanliness, etc. for painting operations. It can limit and treat the paint mist and organic waste gas generated during the spraying operation before discharging. It is an environmentally friendly coating equipment. The mobile oil curtain spray booth is an environmentally friendly spraying equipment that combines the oil film adsorption paint mist technology with the movable structure. It is suitable for surface coating in the fields of automotive parts, engineering machinery, etc. In 2025, mainstream equipment will achieve a paint mist capture rate of ≥99% through the oil curtain circulation purification system and modular design, while supporting rapid disassembly and site switching, meeting efficient production and strict environmental protection requirements (in compliance with ISO 14001 standards).

1. Technical comparison with traditional oil curtain rooms

2. Application scenarios and advantages

Scenario: Batch spraying of automotive sheet metal parts
Coating of agricultural machinery and rail transit parts
Core advantages: Zero site transformation: Rapid deployment, adapting to temporary or leased factories; Ultra-low emissions: Oil curtain adsorption + nano-catalysis dual-stage purification; Cost reduction and efficiency improvement: Waste oil regeneration technology reduces the cost of consumables by more than 50%.
Through dynamic oil film control and IoT upgrades, mobile oil curtain spray booths have become the core solution for green painting in 2025, taking into account both efficient production and sustainable development needs.

Main structures and components:

1. Core structure and functional components

1. Mobile frame system
Material: lightweight aluminum alloy + galvanized steel composite structure, corrosion-resistant and strong load-bearing capacity (load ≥ 500kg/m²).
Moving mode: universal wheel + hydraulic lifting device, supports manual/electric translation, suitable for uneven ground.
2. Oil curtain circulation system
Oil curtain generation module: Oil tank: stainless steel, volume 200-500L (oil content adjustable).
Oil pump: variable frequency control of oil film thickness (0.1-0.3mm), uniform coverage of paint mist capture surface.
Oil purification: centrifugal separator: separate paint residue and waste oil, recycling rate ≥ 80%.
Nanocatalytic purification: new technology added in 2025, degrading VOCs in oil and extending oil change cycle by 3 times.
3. Paint mist capture structure
Oil curtain wall: inclined multi-stage oil curtain design, paint mist adsorption efficiency ≥ 99%.
Post-filtration: G4 filter cotton + activated carbon layer (spare), to cope with high-concentration spraying conditions.
4. Air supply and exhaust system
Centrifugal fan: air volume 10000-25000m³/h, static pressure ≥ 800Pa.
Air flow guidance: bottom air supply + top exhaust, forming laminar flow to reduce paint mist escape.
5. Intelligent control system
Oil film monitoring: infrared sensor detects the uniformity of oil curtain in real time and automatically adjusts the speed of oil pump.
IoT management: supports mobile phone APP remote monitoring of oil volume, energy consumption and fault alarm (upgrade function in 2025)
