Dry spray booth is an environmentally friendly coating equipment that treats paint mist by physical filtration (non-water washing). The core principle is that the multi-stage filtration system absorbs paint mist particles. It is suitable for surface spraying operations such as automobiles, furniture, and machinery. Advantages: low energy consumption, convenient maintenance, no wastewater discharge, and suitable for small batch production. Dry spray booth system process: [air intake section] → [equalizing chamber] → [spraying operation area] → [paint mist filtration section] → [waste gas treatment section] → [exhaust section] Optional accessories Activated carbon adsorption device: used for deep treatment of organic waste gas (VOCs) to meet strict environmental protection standards. Intelligent differential pressure monitoring: automatically prompts the blockage status of filter cotton to reduce manual inspection costs. Heat recovery system: recycles exhaust heat to reduce energy consumption. Dry spray booths achieve efficient paint mist treatment through modular design, and the core relies on the coordinated operation of the filtration system and negative pressure exhaust. It has a simple structure and wide adaptability, making it an ideal choice for small and medium-sized painting scenes.
1. Main structural components
Structural module | Functional description |
1. Room structure | Steel structure or assembled box, the inner wall is corrosion-resistant material (such as galvanized sheet), with sealed door, observation window, etc. |
2. Air supply system | It is composed of primary filter, fan, and pressure equalization chamber to provide uniform clean airflow to ensure a stable spraying environment. |
3. Exhaust system | Negative pressure design, equipped with centrifugal fan and paint mist filter box, forced exhaust gas and intercept particulate matter. |
4. Filtration system | Core module, including paint mist filter cotton (primary effect) and high efficiency filter (secondary), captures more than 90% of paint mist. |
5. Lighting system | Explosion-proof LED light strip, providing shadow-free high-brightness lighting to meet the needs of fine spraying. |
6. Control system | Integrated electric control cabinet, adjusts temperature and humidity, wind speed, pressure difference alarm and other functions. |
2. Detailed explanation of core components
1. Paint mist filter cotton (primary effect)
Location: front end of exhaust system or under floor grille.
Material: multi-layer glass fiber or polyester fiber, can absorb particles larger than 10μm.
Replacement cycle: usually replaced every 200-300 hours according to usage.
2. High efficiency filter (secondary)
Function: further filter fine particles (1-10μm) to improve exhaust gas cleanliness.
Type: bag or plate structure, optional activated carbon layer to absorb VOCs.
3. Floor grille
Design: grid-like steel plate or aluminum alloy, supports the workpiece and guides the airflow downward, and collects paint residue with filter cotton.
