Embodiment 1
[0038] Preparation of solid-liquid mixture:
[0039] Put cotton and crop straw into an oven at a mass ratio of 5:1, dry at a temperature of 60°C for 2 hours, put them into a pulverizer after drying, and mix them to obtain a mixed material. The hydrochloric acid of % is dropped in the beaker as 1:10 by mass ratio, stirs 30min with the rotating speed of 120r / min with stirring device, leaves standstill 5h after stirring and makes solid-liquid mixture;
[0040] Preparation of reaction slurry:
[0041] Place the above beaker in a resistance heating mantle, add dropwise a sodium hydroxide solution with a mass fraction of 20% of the solid-liquid mixture and a mass fraction of 8% into the beaker, raise the temperature of the heating mantle to 80°C after the dropwise addition, and heat at a constant temperature for 60 minutes to prepare Reaction slurry, the reaction slurry and silicon dioxide powder are put into the reactor in a mass ratio of 50:1;

Embodiment 2
[0053] Preparation of solid-liquid mixture:
[0054] Put cotton and crop straw into an oven at a mass ratio of 5:1, dry for 2.5 hours at a temperature of 65°C, put them into a pulverizer after drying, and mix them to obtain a mixed material. The hydrochloric acid of 7.5% is dropped in the beaker as 1:10 by mass ratio, stirs 35min with the rotating speed of 135r / min with stirring device, leaves standstill 5.5h after stirring and makes solid-liquid mixture;
[0055] Preparation of reaction slurry:
[0056] Place the above beaker in a resistance heating mantle, add dropwise a sodium hydroxide solution with a mass fraction of 22.5% of the solid-liquid mixture and a mass fraction of 10% into the beaker, raise the temperature of the heating mantle to 90°C after the dropwise addition, and heat at a constant temperature for 70 minutes. Reaction slurry, the reaction slurry and silicon dioxide powder are put into the reactor in a mass ratio of 50:1;

Embodiment 3
[0068] Preparation of solid-liquid mixture:
[0069] Put cotton and crop straw into an oven at a mass ratio of 5:1, dry for 3 hours at a temperature of 70°C, put them into a pulverizer after drying, and mix them to obtain a mixed material. The hydrochloric acid of % is dropped in the beaker as 1:10 by mass ratio, stirs 40min with the rotating speed of 150r / min with stirring device, leaves standstill 6h after stirring and makes solid-liquid mixture;
[0070] Preparation of reaction slurry:
[0071]Place the above beaker in a resistance heating mantle, add dropwise a sodium hydroxide solution with a mass fraction of 25% of the solid-liquid mixture and a mass fraction of 12% into the beaker, raise the temperature of the heating mantle to 100°C after the dropwise addition, and heat at a constant temperature for 80 minutes to prepare Reaction slurry, the reaction slurry and silicon dioxide powder are put into the reactor in a mass ratio of 50:1;
