Furniture Spray Painting, Automobile Spray Painting, Hardware Spray Painting
A large amount of paint mist dust (containing resins, pigments, solvents and other components) is generated during the spray painting process, with extremely fine particle sizes (0.1-10μm) and medium concentrations (300-1500mg/m³); paint mist is highly viscous, flammable and explosive, and is accompanied by the emission of volatile organic compounds (VOCs); the operating environment is mostly closed spray booths, but there is still a risk of paint mist diffusion; the concentration and diffusion range of paint mist generated by different spray painting processes (such as electrostatic spray painting and air spray painting) are different.
The solvents in paint mist are flammable and explosive substances. When mixed with air to reach the explosive concentration limit, they can easily cause fires or explosions when exposed to ignition sources;
Inhalation of paint mist can cause respiratory inflammation and poisoning, and long-term exposure may induce blood diseases or cancer; skin contact is likely to cause allergies;
Excessive emission of paint mist and leakage of VOCs will cause air pollution, facing strict environmental penalties;
The diffusion of paint mist will pollute the surface of workpieces to be processed, leading to problems such as uneven spray painting and sagging, and reducing product qualification rate.
Integrated Paint Mist Purification + VOCs Adsorption Solution
An integrated purification solution of "pretreatment + paint mist purification + VOCs adsorption" is adopted. First, pretreatment is used to remove large-grained impurities in the paint mist, then special paint mist purifiers are used to purify fine particle paint mist, and finally activated carbon adsorption devices are used to treat VOCs, realizing the coordinated purification of paint mist and waste gas; the operating area adopts a fully closed spray booth design to ensure that paint mist does not diffuse.
Water curtain cabinets or pump-less water curtains, which use water curtains to capture large-grained paint mist, reducing the load of subsequent purification equipment;
Honeycomb activated carbon paint mist purifiers, selecting activated carbon filter materials with high adsorption capacity, removing both paint mist and part of VOCs, and the filter materials can be replaced or regenerated regularly;
If the environmental protection requirements are high, photocatalytic oxidation equipment is matched to further decompose residual VOCs;
The spray booth is equipped with an efficient ventilation system to ensure a negative pressure environment in the booth and avoid paint mist escape; the pipelines are made of anti-adhesive materials and cleaned regularly to avoid paint mist blockage.
The filtration precision of the paint mist purifier must be ≥0.1μm, the filtration efficiency ≥99.9%, and at the same time, it must be matched with VOCs treatment devices to ensure that waste gas emissions meet the standards;
The interior of the equipment must adopt anti-adhesion coatings, and the pipelines are made of large-diameter and smooth materials to avoid paint mist adhesion and blockage;
Equipped with explosion-proof motors, fans and static elimination devices, and combustible gas concentration monitors are set in the spray booth, which automatically shut down and alarm when exceeding the standard;
Adjust the equipment specifications according to the spray painting process (electrostatic spray painting/air spray painting) and workpiece size. Large workpiece spray booths select large-air-volume purification systems, and small workpieces can select mobile spray painting purification equipment.

Answer: It can be judged in two ways: ① Third-party testing: Entrust a qualified environmental protection testing agency to test the dust concentration at the equipment outlet to ensure compliance with relevant standards such as the "Integrated Emission Standard of Air Pollutants" (GB 16297-1996); ② Equipment monitoring: Select equipment equipped with dust concentration monitors to view the real-time dust concentration data at the outlet and intuitively judge the purification effect.
Answer: The maintenance cost of dust removal equipment is relatively low, mainly including three parts: ① Accessory replacement: Filter materials (filter bags, filter cartridges) are the main wearing parts. The replacement cycle depends on the working conditions (generally 3-12 months). The replacement cost of high-quality filter materials accounts for about 5%-10% of the total equipment price; ② Energy consumption cost: The fan operates with electricity. Our equipment adopts high-efficiency and energy-saving fans, and the energy consumption is 15%-20% lower than the industry average; ③ Labor cost: Daily cleaning of accumulated dust and equipment inspection are simple operations that do not require special personnel on duty, resulting in low labor costs.
Answer: We ensure safety through "triple protection": ① Equipment explosion protection: Select motors, fans and electrical components with explosion-proof grades meeting industry standards, and the equipment shell adopts an explosion-proof design; ② Explosion suppression: Equipped with explosion vents, flame arresters and explosion suppression devices. Explosion vents can release pressure in an instant during an explosion, flame arresters prevent the spread of explosion flames, and explosion suppression devices can quickly extinguish explosion flames; ③ Monitoring and early warning: Equipped with dust concentration, temperature and pressure monitors to monitor the equipment operation status in real time. When parameters are abnormal, it automatically warns and shuts down to avoid danger.
Answer: The installation cycle depends on the project scale. Small-scale decentralized equipment (such as mobile welding fume purifiers) is simple to install and can be completed in 1-2 days; the installation cycle of large-scale central dust collection systems is about 7-30 days. We will communicate with customers in advance to formulate a reasonable installation plan, and try to choose production gaps and holidays for installation to reduce the impact on normal production; for large-scale projects, phased installation and commissioning can be adopted to ensure the normal operation of some production lines.
Answer: Universal use is not recommended. The dust working conditions (concentration, particle size, physical and chemical properties) of different industries are quite different. For example, heavy metal dust in metal processing, flammable and explosive dust in the chemical industry, and ultra-fine dust in the electronics industry have completely different requirements for equipment filtration precision, explosion-proof performance and material. Universal equipment cannot accurately adapt to working conditions, which may lead to substandard purification effects, equipment damage and even safety accidents. We recommend customizing exclusive equipment according to the specific industry working conditions.
Answer: If a fault occurs in the equipment, it can be handled in the following steps: ① Emergency shutdown: In case of serious faults (such as abnormal noise, peculiar smell, dust leakage), immediately cut off the equipment power supply to avoid expanding the fault; ② Contact after-sales service: Call our 24-hour after-sales hotline to explain the fault phenomenon, equipment model, working conditions and other information; ③ On-site processing: Technical personnel from nearby service outlets will arrive at the scene within 2-8 hours to troubleshoot and repair; ④ Emergency support: For key production links, we can provide temporary backup equipment to ensure uninterrupted production.
