Systems, methods, and vessels for reducing the stagnation and non-uniform flow or treatment of solid materials and slurries in vessels. The non-uniform flow or treatment that may characterize the storage or treatment of solid materials in process industries is minimized or eliminated by the introduction of liquid to the bottom heads of the vessels, in particular, the introduction of liquids in regions in the bottom heads where friction and compression cause stagnation in the flow of material. The liquid may be introduced by means of one or more nozzles, for example, one or more evenly-spaced nozzles, and the flow of liquid to each nozzle may be individually controlled. Though the systems, methods, and vessels disclosed may be used in the processing of cellulose materials, aspects of the present invention may be used in any process or materials handling industry application where solid materials or slurries are handled in vessels.
A system for improving the movement of material in a vessel, the vessel having an inlet, an outlet, a cylindrical portion having an outer dimension, and a converging transition between the cylindrical portion and the outlet, the system comprising:
A method of treating particulate material in a cylindrical vessel having an interior, an inlet into which particulate material is introduced, and an outlet from which particulate material is discharged, the method comprising:
A digester for treating comminuted cellulosic fibrous material, the digester comprising:
A method of treating comminuted cellulosic fibrous material in a digester, the digester having an interior, an inlet for introducing comminuted cellulosic fibrous material, and an outlet for discharging treated comminuted cellulosic fibrous material, the method comprising:
