| titleOfInvention | Surface modification combined treatment method of fumed silica |
| abstract | The invention relates to a surface modification combined treatment method of fumed silica, which comprises the following steps: (1) the method comprises the following steps of (1) jointly treating fumed silica by two groups of modification devices, and modifying the fumed silica by using a modifier in a reaction furnace of each group of modification devices to respectively obtain two groups of modified fumed silica and waste gas; (2) and (2) respectively separating the waste gases obtained in the step (1) to obtain unreacted modifiers and byproducts, inputting the byproducts serving as reaction auxiliaries into a reaction furnace of another group of modification devices to participate in modification reaction, and returning the obtained unreacted modifiers to the reaction furnace of the original modification device for reuse. According to the method, two groups of modification devices connected in parallel are arranged, and the types of the modifiers in each group of modification devices are controlled, so that the efficiency of modification reaction is improved mutually, the effects of high efficiency, energy conservation and zero emission are realized, and the method has a good application prospect. |
