What is VOCs and where does it come from?
Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility. For example, formaldehyde, which evaporates from paint and releases from materials like resin, has a boiling point of only -19 °C (-2 °F).
VOCs are numerous, varied, and ubiquitous. They include both human-made and naturally occurring chemical compounds. Most scents or odors are of VOCs. Some VOCs are dangerous to human health or cause harm to the environment. Anthropogenic VOCs are regulated by law, especially indoors, where concentrations are the highest. Harmful VOCs typically are not acutely toxic, but have compounding long-term health effects.
VOCs emissions and hazards
1. PM2.5 hazard
2. O3 hazard
3. Direct harm to the human body
Vocs Integrated Treatment Equipment for Industrial Waste Gas This adsorption concentration equipment is a new generation of VOCs treatment equipment, which organically combines the adsorption concentration unit with thermal oxidation unit, mainly applicable to organic wastes of large air volume and low concentration, which can be converted into the ones of small air volume and high concentration after purification by adsorption and desorption. Then to have thermal oxidation treatment, and the heat emitted by the combustion of organic matter is utilized effectively.
