| titleOfInvention | Manufacturing method of ferrous sulfate based on sludge |
| abstract | In the acid treatment process for galvanizing pipes, the wastewater generated after the acid treatment is subjected to alkali treatment and then sludged. The present invention relates to a method for producing ferrous sulfate having high quality by heating and stirring to a predetermined temperature, wherein ferrous sulfate based on sludge produced by treating waste acid and wastewater, which are by-products generated for plating metal materials such as iron, as raw materials In the method for producing, the sludge and waste acid and sulfuric acid is added to the first reactor 10 and then heated using a pressurized steam, while stirring using a stirrer 18, while maximizing the particles with pressure air In this case, the generated gas is separated into the gas cleaner 14, and the semi-finished product generated at this time is unstable, and thus, the second reactor 12. After adding iron and sulfuric acid to the semi-finished product, it is heated using a pressurized steam as in the first reactor 10 and stirred using an agitator 18 to maximize the particles with pressure air. The gas and the like are separated by the gas cleaner 14, and the produced product is characterized in that the ferrous sulfate is obtained by removing impurities using the filtration device 16. |
