The invention has the beneficial effects that:
1. the alkali metal slag is fully combusted and then digested by water, so that the alkali metal slag can be digested more thoroughly, and dangerous safety accidents of explosion can be avoided.
2. The arrangement of the slag removal device ensures that the incompletely combusted alkali metal slag is continuously combusted for a period of time, thereby ensuring the conversion rate of the alkali metal into oxide.
3. The digestion tank is in a negative pressure environment, so that toxic particles generated can be well prevented from being emitted into the air, and the effect of protecting the environment is achieved.
