| titleOfInvention | Method for preparing aerogel by supercritical drying method and device for supercritical drying |
| abstract | The present invention relates to a method for preparing aerogel by supercritical drying method and an apparatus for supercritical drying. The method comprises the following steps: placing the wet gel containing the solvent in a drying kettle; carrying a functional modifier with the supercritical drying fluid; and after uniformly dispersing the fluid by using a uniform distributor, performing supercritical drying on the wet gel, and then discharging the fluid to obtain the aerogel. The device comprises: a circulating fluid storage tank for storing supercritical drying fluid, a chemical reagent storage tank for storing functional modifier, a pressure pump for sending the fluid into the chemical reagent storage tank, at least one drying kettle with a fluid inlet, at least one separation kettle, a recovery tank, a compression pump and a condenser which are sequentially communicated with each other, wherein the condenser is also communicated with the circulating fluid storage tank in a fluid mode; the fluid inlet of the drying kettle is provided with a uniform distributor. The method and the device have high drying efficiency, can ensure that the pore structure of the aerogel is uniformly distributed, and can directly prepare the functional aerogel. |
