Embodiment 1
[0021] The volume of the reactor is 25m³, the volume of the silo is 3m³, 1.5 tons of aluminum scraps are fed into the single kettle, 16.8 tons of 8wt% hydrochloric acid, and the output of the single kettle is 13 tons. Add 1 / 4 first, and after 30 minutes, the temperature will rise to 75°C, and the temperature will not continue to rise, and white water vapor will overflow from the vent. After maintaining the temperature for 20 minutes, continue to add dilute hydrochloric acid to the reactor, observe the temperature change during the dosing process, and adjust the feeding speed. After the temperature rises to 90°C, add a small amount of dilute hydrochloric acid to maintain the temperature for reaction , A small amount of overflow liquid flows from the reactor overflow port into the circulation storage tank, through the overflow port, it can prevent the tank from leaking. After the hydrochloric acid is added, slowly add the feed liquid from the circulation storage tank to the react...
Embodiment 2
[0023] The volume of the reactor is 35m³, the volume of the silo is 5m³, 3 tons of aluminum chips are fed into the single kettle, 25.6 tons of 10wt% hydrochloric acid, and the output of the single kettle is 15 tons. Add 1 / 3 first, and after 20 minutes, the temperature will rise to 80°C, and the temperature will not continue to rise, and white water vapor will overflow from the vent. After maintaining the temperature for 15 minutes, continue to add dilute hydrochloric acid to the reactor, observe the temperature change during the dosing process, and adjust the feeding speed. After the temperature rises to 100°C, add a small amount of dilute hydrochloric acid to maintain the temperature for reaction , A small amount of overflow liquid flows from the reactor overflow port into the circulation storage tank, through the overflow port, it can prevent the tank from leaking. After the hydrochloric acid is added, slowly add the feed liquid from the circulation storage tank to the reacto...
Embodiment 3
[0025] The volume of the reactor is 30m³, the volume of the silo is 3m³, 2 tons of aluminum chips are fed into the single kettle, 20.5 tons of 9wt% hydrochloric acid, and the output of the single kettle is 14.5 tons. Add 1 / 6, and after 35 minutes, the temperature rises to 70°C. After the temperature does not continue to rise, white water vapor will overflow from the vent. After maintaining the temperature for 30 minutes, continue to add dilute hydrochloric acid to the reaction kettle. During the dosing process, pay attention to observe the temperature change and adjust the feeding speed. After the temperature rises to 97°C, add a small amount of dilute hydrochloric acid to maintain the temperature for reaction , A small amount of overflow liquid flows from the reactor overflow port into the circulation storage tank, through the overflow port, it can prevent the tank from leaking. After the hydrochloric acid is added, slowly add the feed liquid from the circulation storage tank ...
