| titleOfInvention | Method for preparing small-particle-size lake in continuous-flow microchannel reactor |
| abstract | The invention discloses a method for preparing small-particle-size lake in a continuous flow microchannel reactor, which comprises the following steps of: the method comprises the following steps: preparing aluminum chloride and sodium bicarbonate solution; step two: introducing an aluminum chloride solution and a sodium bicarbonate solution into a microchannel reactor through a metering pump to perform aluminum hydroxide carrier preparation reaction, controlling the flow rate, the molar ratio of aluminum chloride to sodium bicarbonate, the reaction temperature and the residence time of a reaction solution in the microchannel reactor, obtaining an aluminum hydroxide suspension after the reaction is finished, and filtering and washing the aluminum hydroxide suspension to obtain active aluminum hydroxide for later use; step three: preparing a color lake; step four: removing chloride ions from the lake to obtain a lake product with the particle size of less than 1.5 mu m. The invention adjusts and strengthens the mixing effect through mass transfer strengthening of micro-channel equipment and a large number of experiments, thereby preparing the active aluminum hydroxide matrix with small grain diameter, and obtaining the lake with the grain diameter lower than 1 mu m through loading pigment. |
