| titleOfInvention | A waste sulfuric acid treatment device |
| abstract | The utility model relates to a treatment device, in particular to a waste sulfuric acid treatment device. The technical scheme of the utility model is as follows: in the process of industrial production of fluorobenzene and methyl fluorobenzene, the waste sulfuric acid and the stone powder slurry produced in the process of recovering hydrogen fluoride are chemically reacted to obtain gypsum. The advantages and positive effects of adopting the above technical scheme are: harmless treatment of waste sulfuric acid, which not only protects the environment, but also produces economic value. The process is simple, turning waste into treasure. |
