| titleOfInvention | Device of comprehensive utilization combined process for chemically decomposing waste sulphuric acid and gypsum |
| abstract | The utility model belongs to the technical field of comprehensive utilization of industrial waste sulphuric acid, and in particular relates to a device of a comprehensive utilization combined process for chemically decomposing waste sulphuric acid and gypsum. The device is realized by being combined with the traditional device for co-producing sulphuric acid and cement from gypsum. The device disclosed by the utility model comprises a calcining kiln, a sulphuric acid preparation system and a cement grinding system, wherein the sulphuric acid preparation system is in pipeline connection with the kiln tail of the calcining kiln; the cement grinding system is connected with the kiln head of the calcining kiln; a coal gun and a acid gun I are arranged at the kiln head of the calcining kiln; an acid gun II is arranged at the kiln tail of the calcining kiln. The device disclosed by the utility model is a co-production device for economically recycling and treating waste sulphuric acid, such as alkylation and the like, with the help of a device for preparing sulphuric acid and cement from gypsum; a cracking device is unnecessary to be additionally arranged; a lot of waste sulphuric acid can be treated effectively and rapidly by utilizing existing resources; simultaneously, waste sulphuric acid is turned into wealth, therefore, novel resources are circularly generated; the device disclosed by the utility model is environment-friendly and economic. |
