Abstract:
1. A device configured to disperse a substance in a liquid, comprising: at least one dispersing chamber comprising: at least one rotatable impeller which is arranged in the at least one dispersing chamber and includes vanes, each of which extends from a base, the at least one rotatable impeller being configured to, during rotation, accumulate the liquid fed into the at least one dispersing chamber and set the liquid into motion in the at least one dispersing chamber in the form of a liquid ring within which is formed a plurality of cavities of varying respective volumes each limited by the liquid ring, wherein the rotatable impeller and the at least one dispersing chamber are configured so that, when the rotatable impeller is in rotation, the distance between the base of each vane of the rotatable impeller and the peripheral wall of the at least one dispersing chamber changes recurrently in order to vary the volume of each cavity; and wherein the at least one substance inlet and the outlet are configured such that the rotation of the at least one rotatable impeller causes the substance to be sucked in through the at least one substance inlet into the inside of the at least one dispersing chamber and to be expelled together with liquid from the liquid ring through the at least one outlet after the substance has been wetted with the liquid of the liquid ring.
