Volatile organic compounds broadly refer to the general name of volatile organic compounds with a melting point below room temperature and a boiling point of 50-260oC. VOCs refer to hydrocarbons, ketones, alcohols, phenols, Organic compounds such as aldehydes.
The spray tower is widely used in the industrial waste gas treatment and purification industry. It can effectively remove dust, adhesive substances and some waste gas components. It has solved the waste gas problem for many factories for many years. However, due to the continuous requirements of environmental protection and people's quality of life In many cases, the spray tower can no longer meet the needs of environmental protection. The upgrade of the spray tower is imperative. The special deodorant for the spray tower becomes a simple and low-cost way to upgrade the spray tower.
Preventive technology based on improving process technology and updating operating equipment is the best choice to achieve VOCs reduction. In the petrochemical industry, crude oil extraction, oil storage, transportation, distribution and other production links are prone to evaporative loss of oil or solvent, which is an important source of VOCs emissions. Evaporative emission control technologies for VOCs include floating roof tank technology, steam recovery, and gas recovery at gas stations.
The adsorption method is a purification method that uses the molecular attractive force and chemical bond existing on the solid surface to adsorb VOCs components on the porous solid surface, thereby separating the VOCs from the exhaust gas. The condensing method uses the property that VOCs have different saturated vapor pressures at different temperatures, and adopts a method of reducing temperature, increasing pressure, or both reducing temperature and increasing pressure to condense VOCs in a vapor state and then separate them from exhaust gas. The condensing method is often used as a pre-purification treatment for other methods to handle high-concentration organic gases.
The special deodorant for the spray tower
uses the international advanced plant extraction technology to extract effective ingredients from the roots, stems, leaves and flowers and fruits of more than 300 plants, which produces a huge force under the action of high-energy rays and improves the activity of plant fluids. It can react with various harmful, odorous molecules to polymerize, replace, replace, and absorb chemical reactions quickly. The product is neutral, non-toxic, non-flammable, non-corrosive, and non-secondary pollution. It is effective in removing waste gas, odor, and odor. Environmentally friendly products.
According to the principle of VOCs generation in the atmosphere and the physical and chemical properties of VOCs, its control technology can be divided into two categories, process control and end control. Process control is aimed at the generation process of VOCs, which reduces the generation of VOCs from the principle of VOCs, which is generally achieved through process upgrading, technological transformation and leakage control. The end control is based on the chemical characteristics of VOCs, focusing on the treatment of VOCs exhaust gas, using combustion, decomposition and other methods to control VOCs emissions.
The plant extract quickly decomposes various odor molecules in the air, and the decomposed products are harmless substances, such as water, oxygen, nitrogen, etc., and will not cause secondary pollution. Plant extracts are characterized by rapidly decomposing and eliminating odorous molecules in the air, rather than masking odors.
