Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.
All industries produce wastewater. Cleaning, cooling and other processes result in industrial wastewater that can be harmful to the environment. Draygon`s Industrial Wastewater Evaporators distill the water from the particulate matter and waste, leaving only a small residue that can easily be disposed of. By reducing the need for storage and expensive hauling of large quantities of industrial wastewater, our industrial wastewater treament systems save money and help protect the environment.
Dürr MEGTEC provides custom-designed atomizing technologies and air pollution control solutions for the non-ferrous metallurgical industry, including aluminum, copper, nickel, zinc, and precious metals producers. Our evaporative gas cooling and conditioning system controls high-temperature furnace and converter off-gases, lowering them to temperatures below other spray technologies without wetting problems.
Evaporative gas cooling and conditioning systems use specially engineered atomizing nozzles that introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates completely while absorbing heat from the gases, which results in free-flowing dust, zero liquid discharge, and minimal or no problems with scale buildup on the walls.
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
The evaporative gas cooling and conditioning system uses a finely atomized water spray to cool EAF, BOF off-gases from over 2,400°F (1,315°C) to as low as 240°F (115°C), protecting ductwork and downstream air pollution control equipment from high temperature and sparks, while providing rapid cooling for dioxin and furan control. By optimizing humidity levels, it helps electrostatic precipitators because the water spray completely evaporates while cooling the gases. There is no free water and no...
