Industrial automotive spray painting equipment

Automotive paint booth equipment is a closed or semi closed device designed specifically for automotive painting operations. By accurately controlling temperature, humidity, air cleanliness, and airflow direction, it provides a dust-free and stable environment for the painting process. At the same time, it efficiently processes paint mist and exhaust gas, ensuring uniform coating quality, high glossiness, and safeguarding the health and safety of operators.
It is divided into two types: dry and wet. Dry type uses multi-layer filter cotton as the core, while wet type uses water curtain or water spin technology to absorb paint mist and adapt to different process requirements.

Efficient purification: The two-stage filtration system (coarse efficiency+precision filtration) can capture dust particles with a diameter greater than 4 microns, with a purification efficiency of over 98%, ensuring clean air in the working environment.

Uniform air supply: Adopting an upward air supply and downward exhaust mode, the airflow forms a vertical air curtain at a speed of 0.3-0.5 meters per second, avoiding paint mist from staying in the operator's breathing zone and improving the uniformity of spraying.

Energy saving and environmental protection: Infrared heating technology accelerates the curing of paint film and reduces drying time; Heat exchangers recover waste heat and reduce energy consumption; Water curtain treatment of paint mist reduces exhaust emissions.

Safe and reliable: Explosion proof lighting fixtures, explosion-proof electrical appliances, and pressure relief devices ensure safe operations, sealed structures prevent paint dust accumulation, and comply with industrial safety standards.

Easy to operate: Modular design supports quick assembly and maintenance, automated control system simplifies the operation process, and reduces the need for manual intervention.

Automotive paint booth equipmentworking principle

Spray painting stage: After being purified by the primary filter, the external air is sent into the static pressure chamber on the roof by the fan, and then further purified by the top filter cotton. It flows vertically downwards at a speed of 0.3-0.5 meters per second to form an air curtain that wraps around the workpiece. The paint mist flows through the bottom water curtain and is absorbed before being discharged.

Drying stage: The infrared heater rapidly raises the temperature inside the room to 40-60 ℃, accelerating the curing of the paint film. The heat exchanger recovers waste heat for preheating the fresh air, forming an energy cycle.

Waste gas treatment: Wet equipment captures paint mist through a water curtain, while dry equipment relies on activated carbon or catalytic combustion technology to decompose organic matter, ensuring emissions meet standards.

Application fields:

Furniture manufacturing: suitable for surface spraying of wooden, metal, and plastic furniture, meeting the uniform spraying requirements of irregular furniture and complex curved surfaces.

Industrial coating: provides a dust-free spraying environment for mechanical equipment and metal structures, ensuring coating quality and durability.

Car maintenance: Solve the problem of insufficient sheet metal spraying stations in 4S stores and repair shops, and support body repair and repainting.

Heavy Machinery: Handling ultra long workpieces such as excavator booms and wind turbine towers, breaking through the size limitations of fixed paint booths.

Aerospace: Meet the cleanliness requirements for special primer spraying on aviation aluminum materials, ensuring stable coating performance.

Precautions for use:

1. Ventilation and airflow control: Ensure the normal operation of the air supply and exhaust system, maintain micro positive pressure and directional airflow (usually from top to bottom), prevent paint mist from overflowing, and ensure even spraying.

2. Maintenance of filtration system: Regularly check and replace the top cotton, floor cotton, and paint mist filters to avoid blockages that affect air flow and purification efficiency.

3. Temperature and humidity management: The spraying environment temperature should be controlled at 20-28 ℃, with a relative humidity of 40% -70%, to ensure the quality of the paint film.

4. Fire and explosion safety: Open flames are strictly prohibited in the paint booth, and electrical equipment must be explosion-proof; Install combustible gas (LEL) alarm device, and automatically interlock and shut down when the exhaust gas concentration exceeds the limit.

5. Linkage of exhaust gas treatment: Spray painting exhaust gas must be effectively treated (such as zeolite wheel+RTO/CO) to ensure standard emissions, and the treatment equipment should be regularly maintained.

6. Operating standards: Operators should wear protective equipment, clean the workpiece before spraying, and operate according to process parameters (spray gun pressure, distance, gun speed) to improve coating quality and efficiency.
