An open pressurized stirred tank reactor and a method for mixing gas and grout with each other

摘要

An apparatus for processing a slurry with a high solids content or with solids of high specific gravity and a gas fed into it, whereby the apparatus (1) comprises at least one open vertical reactor (2), consisting of two nested pipes, an inner tube and an outer tube (4,5), in which the inner tube is provided with a downdraft mixer and elements (17) to intensify the gas supply, characterized in that it is fixed to The lower section of the vertical reactor is a cylindrical horizontal reactor (3), which is provided with radial mixers (7) that fluidize the solids and produce a flow of circulation from the horizontal reactor to the outer tube (5) of the vertical reactor.
