Paint mist purification machine catalog 123456 catalog 123456 paint mist purification machine, commonly known as, the process purpose of this technology equipment is to purify the over-spray mist in the painting process of workpieces as much as possible. The significance of the paint mist purification machine is to achieve internal and external environmental protection purposes. It protects the physical and mental health of operating employees and reduces public nuisances. The paint mist purification machine is one of the essential devices in the spray painting and coating production line process.
The paint mist purification machine uses paint mist filtration material as the core component. Spray painting exhaust passes through multiple layers of gradually denser flame-retardant glass fiber material. Paint mist particles are intercepted, collided with, and absorbed by these materials, eventually being accommodated within them and gradually weathering into a powdered form, thereby achieving the purpose of purifying paint mist.

Scope of application: This device can be widely used for the purification treatment of low-concentration organic exhaust gas produced in industries such as petroleum, chemical, rubber, paint, coating, furniture, home appliances, and printing. It can handle various types of organic substances including benzene compounds, ketones, esters, alcohols, ethers, and alkanes. This equipment consists of an oil mist absorption section, gas-liquid separation section, centrifugal separation section, high-efficiency filtration section, low-temperature plasma purification section, and activated carbon adsorption deodorization section. When the oil mist purification unit is in operation, the paint mist first enters the atomization absorption section, where waste engine oil atomization absorbs paint mist molecules, reducing the concentration of benzene-containing exhaust gases; after absorption, the paint mist exhaust then enters the gas-liquid separation section, where oil molecules and paint mist molecules are separated from the gas-liquid separator through inertial collision and turbulent collision. Subsequently, under the high-speed rotation of the fan impeller, the centrifugal force continuously changes the flow rate and direction of the paint mist, causing it to collide, compress, and coalesce on the impeller. The coagulated paint mist forms micro-particles and is thrown onto the inner wall of the box by centrifugal force, flowing out through the liquid leakage pipe.
After centrifugal separation, most of the paint mist molecule particles have been removed. The escaped molecules then enter the ultra-fine sponge filtration section, where the larger specific surface area of the ultra-fine sponge strongly retains oil and paint mist molecules. After the paint mist molecules and oil mist molecules have been basically removed through the first four levels of purification, they then enter the plasma purification zone and deodorization zone, where micron and sub-micron level molecules are degraded, sterilized, disinfected, and deodorized before emitting completely clean gas.
Currently, the coatings used in spraying still primarily use solvents. Organic solvents such as benzene, toluene, and xylene (collectively referred to as "three benzenes") directly volatilize from the surface of the paint film and the paint mist into the workshop air. At the same time, tiny paint mist droplets form dust after solvent evaporation, which also disperses in the workshop air. The three benzenes belong to highly toxic solvents. During operations, they are released into the workshop air, and workers inhale them through their respiratory systems, potentially causing acute and chronic poisoning. They mainly harm the central nervous system and hematopoietic system. Short-term inhalation of high concentrations (1500 mg/m³) of benzene vapor can lead to aplastic anemia; frequent inhalation of low concentrations of benzene vapor can cause nausea, vomiting, confusion, and other neurological symptoms, with some cases leading to neurasthenia syndrome. Toluene has a stronger toxicity to the central nervous system than benzene but has less effect on the hematopoietic system. Reports indicate that long-term exposure to benzene concentrations of 188 μg/m³ can cause noticeable subjective symptoms. The chronic hazards of toluene are smaller than those of benzene, but at concentrations of 43-1300 mg/m³, poisoning symptoms may appear. When the three benzenes are mixed together, they can irritate the eyes and nasal mucosa, and the neurological symptoms become more severe. As described above, the hazards of paint mist to workers cannot be ignored.
Under high pressure, paints are atomized into fine particles, but during spray gun application, not all the paint reaches the spray surface. These paint particles form with the airflow. To improve the working environment of workers inside the workshop and meet environmental protection requirements, it is necessary to treat the paint mist for standard emissions. The SCGF-type oil mist purification machine produced by Sci-Tech Environmental Protection Company is designed based on the most practical paint mist purification technologies currently available domestically and internationally, making it the ideal equipment for paint mist purification.
