Mixers are disclosed for the processing of one or more materials to be used, for example, in conjunction with injection molding breaker plates. The disclosed embodiments include the use of multiple integral flow channels having non-linear flow paths that vary in their radial, angular, and axial directions. The cross-section of the flow channels can also vary the nature of distributive and dispersive mixing. A method for the design of the mixers is also disclosed. The use of multiple stages of mixing is also disclosed.

An inlet for an SCR device including a tube having an upstream end for receiving exhaust gases and a downstream end terminating in a porous wall. A plurality of openings are spaced around the circumference of the tube adjacent the porous wall and a plurality of vanes are formed at a connection junction adjacent one edge of the opening to form vanes extending inward at an acute angle relative to a plane between the connecting junction and the longitudinal axis of the tube. Preferably, the vanes are concave on the surface extending inward to promote more effective mixing.

A flow control device for mitigating thermal stratification in a mixing tee pipe includes a mixing bowl provided as an empty sphere; a main pipe having a tubular shape, through which a fluid flows, and coupled to the mixing bowl in linkage with the mixing bowl; a branch pipe having a tubular shape, through which a fluid flows, and coupled to the mixing bowl in linkage with the mixing bowl; and a mixing tee pipe having a tubular shape, through which the fluid in the mixing bowl flows, and coupled to the mixing bowl in linkage with the mixing bowl, wherein a fluid introduced from the main pipe and a fluid introduced from the branch pipe are mixed in the mixing bowl and discharged through the mixing tee pipe.

Each minimizing device has a shell, a minimizing basket with multiple filtrating holes, and a minimizing plate with multiple meshes mounted inside the shell. The electrolytic assembly has at least one electrolytic unit. Each electrolytic unit has a tube having an inlet and an outlet, and a cathode and an anode assembled to the tube.

Methods and systems are provided for a urea mixer. In one example, a urea mixer may include a tube for mixing exhaust gas with urea outside of a main exhaust passage.

A vehicle exhaust system includes an upstream exhaust component comprising at least a first catalyst having a first outer dimension, a downstream exhaust component comprising at least a second catalyst having a second outer dimension, and a mixer that connects the upstream and downstream exhaust components. The mixer comprises a first portion associated with an outlet from the first catalyst and a second portion associated with an inlet to the second catalyst. The first portion includes a swirl component having a first length and the second portion includes an additional component having a second length. A connection interface between the first and second portions allows the upstream and downstream exhaust components to be arranged in different positions relative to each other. A combined length of the first and second lengths is adjusted relative to the first and second outer dimensions to achieve a desired position of the upstream and downstream exhaust components relative to each other.
