A smelter in Sihui, Guangdong is mainly engaged in non-ferrous metal smelting. The company has a copper smelting furnace. The flue gas produced during smelting is harmful to the human body. At the same time, the dust produced by smelting contains toxic and harmful metal oxides such as Pb, Cu, and Zn, and also contains some combustibles. Among them, the ZnO content reaches 30%, so the dust dew point is very low and it is very easy to condense in the air.
Although the company has been equipped with dust removal equipment before, with the country advocating sustainable development and strict environmental protection of enterprises, the bag dust collector installed by the company has been difficult to meet the requirements of environmental protection. After comparing with many environmental protection companies, the person in charge of the company finally chose "Mingfeng Environmental Protection". After investigating the on-site environment, "Mingfeng Environmental Protection" finally chose "desulfurization tower + wet electrostatic equipment".
Features of wet electrostatic dust and mist remover:
1. High efficiency: Under appropriate temperature conditions, the denitrification efficiency can reach 80% or even more than 90%.
2. Strong adaptability: It has a high removal rate for low-concentration to medium-high-concentration NOx flue gas.
3. Dust removal efficiency: The removal rate of PM2.5~PM10 fine dust and aerosol particles is 85%~93%.
4. Demisting efficiency: The removal rate of acid mist and droplets is 85%~97%.
5. Heavy metal removal efficiency: Hg, As and other heavy metal vapors can be condensed in the droplets and removed together, with a removal rate of 75%.
6. Low water consumption: The flushing water can be collected by a water collection tray and recycled through membrane filtration or directly used as water for the desulfurization tower process.
7. Device availability: The availability relative to the desulfurization (denitrification) operation time is not less than 95%.
8. Device service life: The service life of the main equipment is generally designed to be 25~30 years.
For the exhaust gas caused by the emission of PM2.5 (including SO3 acid mist, fly ash particles, gypsum particles, sulfuric acid crystals, fine droplets, and other pollutants) after wet flue gas desulfurization (denitrification), etc.
Applicable to the treatment of desulfurization exhaust gas from smelting furnaces, biomass boiler tail gas, drying furnace exhaust gas, acid mist exhaust gas, power plant coal-fired boilers, non-ferrous metallurgical furnaces, glass production furnaces, cement production furnaces, chemical production lines, textile production lines, and other industries.
