The invention discloses a hydro-
thermal treatment device and method for preparing high-
peptization large-pore-volume pseudo-
boehmite powder, relates to the field of preparation of pseudo-
boehmite powder, and solves the problems that an existing hydro-
thermal treatment device for preparing the high-
peptization large-pore-volume pseudo-
boehmite powder is tedious in operation and prone to deviation during pH value adjustment. Comprising a reaction kettle body, a detection device and a dropwise adding device, a driving motor is fixedly connected to the reaction kettle body, according to the hydro-
thermal treatment device for preparing the high-peptizing large-pore-volume pseudo-boehmite powder, by arranging the detection device and the dropwise adding device,
ammonia water can be intermittently and uniformly sprayed into
slurry when the pH value is adjusted, and the stirring speed is increased; the pH value at the moment is obtained through the detection of the stirring, mixing and detecting device, the
ammonia water is in a non-adding state at the moment, when the pH value does not reach a specified value, the dropwise adding device continues to intermittently add the
ammonia water, and when the pH value reaches the specified value, dropwise adding and detecting are stopped immediately, so that the detection is more accurate, and the working efficiency is improved.
