Abstract:
A mixing apparatus and method uses a disposable assembly including a closed vessel with a rotating shaft supported in the vessel. The shaft has radially extending impellers. The shaft is driven via an external magnetic drive system. The vessel can be cleaned during manufacture and discarded after use.
Abstract:
The invention relates to a mixing apparatus for mixing black liquor from cellulose production with ash from flue gases which is generated on combustion of black liquor. The apparatus, which consists of a cylindrical tank, comprises a stirrer mechanism consisting of a propeller (4) secured on the upper part of a vertical shaft (3), and of radial, vertical baffles (5) secured on the lower part of the shaft (3), and also of stationary, vertical, radial baffles (9) arranged around, and at a distance from, the said baffles (5).
Abstract:
The invention relates to an arrangement and a method for processing organic waste. The invention further relates to use of the method or the arrangement for the processing of organic waste in the form of household waste.
Abstract:
A play dough mixer (10) comprising a mixing vessel (12) having a lower wall (16) and a side wall (18) extending upwardly from the periphery of the circular lower wall (16). A blade (14) is mounted adjacent the lower wall (16) of the mixing vessel (12) for rotation about a rotation axis. The blade (14) comprises a planar member oriented radially with respect to the rotation axis. A drive motor (22) is provided for rotating the blade and one or more longitudinal projections (36) extend inwardly from an inner surface of the side wall (16). Each projection (36) includes a lower face (44) located above and parallel to the lower wall (16) of the mixing vessel (12) such that a gap (46) is defined therebetween. The blade (14) passes through the gaps (46) during rotation.
Abstract:
Disclosed are an oxidation reactor for manufacturing an aromatic carboxylic acid and a method of manufacturing the aromatic carboxylic acid using the oxidation reactor. The oxidation reactor includes a reaction chamber, a stirring shaft disposed along a geometric vertical axis of the reaction chamber, and at least two stirrers, each including stirring blades, each stirring blade having either a curved portion or a bent portion formed on an end of the stirring blade to enable fluid to flow in the reaction chamber while preventing the fluid from remaining in the reaction chamber, and each stirring blade being extended radially along a direction perpendicular to the vertical axis to be rotated.
Abstract:
An aeration system including a frame and an aerator. The aerator may be supported by the frame. The aerator may include an input and an output. The aerator may be configured to rotate with respect to the frame, and upon rotating, receive a first fluid at the input and output the first fluid into a second fluid at the output.
Abstract:
The invention relates to a stirred tank reactor for gas-liquid mass transfer in a slurry. The reactor includes a reactor tank (1) having a first volume (V 1 ), a drive shaft (2) that extends vertically in the reactor tank, a motor (3) for rotating the drive shaft (2), a main impeller (4) which is a downward pumping axial flow impeller attached to the drive shaft (2) to create a main flow pattern in the reactor tank, and a gas inlet (5) arranged to supply gas into the reactor tank (1) to be dispersed to the liquid. The reactor includes a mechanical gas sparging apparatus (6) comprising a dispersion chamber (7) having a second volume (V 2 ) which is substantially smaller than the first volume (V 1 ) of the reactor tank (1), the dispersion chamber being arranged coaxial with the drive shaft (2), and the gas inlet (5) being arranged to feed gas into the dispersion chamber (7), and mixing means (8, 9, 10, 11, 12) arranged within the dispersion chamber (7) for mixing the gas into liquid by dispersing the gas to fine bubbles before the bubbles enter the main flow pattern. The mixing power per unit volume inside the dispersion chamber (7) is significantly larger than the mixing power elsewhere in the reactor.
