| titleOfInvention | Nano calcium carbonate pressurized carbonation and surface modification integrated reaction kettle and application |
| abstract | The invention discloses a nano calcium carbonate pressurized carbonation and surface modification integrated reaction kettle and application thereof 2 And a modifier delivery conduit; a stirring shaft is arranged in the main reaction kettle, a main reaction kettle motor is arranged above the stirring shaft, the main reaction kettle motor is arranged at the top of the reaction kettle, and a main reaction kettle stirrer is arranged on the stirring shaft; the slurry inlet pipeline is arranged at the middle upper part of the main reaction kettle, the slurry discharge pipeline is arranged at the bottom of the main reaction kettle, and the CO is 2 And the modifier conveying pipeline extends from the main reaction kettle to the lower part of the stirrer. The invention carries out the carbonation reaction and the surface modification of the nano calcium carbonate in one reaction kettle, and the slurry does not need to be pumped to other reaction kettles, thereby effectively controlling the unreacted calcium hydroxide suspension to enter a surface modification system, improving the product quality, simplifying the flow, improving the production efficiency of the calcium carbonate and reducing the equipment cost. |
