A mixing and dispensing device and method. In particular, the device used by the applied method reduces the risk of chlorine gas formation while providing a stable, effective and safe disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device includes a highly concentrated disinfectant and dilutes the concentrate through the device while simultaneously mixing the concentrate with a dilute solution of an organic acid. The two diluted solutions are mixed without production of chlorine gas and to a level of safety before being dispensed to produce the stable, effective and safe neutral pH sodium hypochlorite solution disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device can be in the form of a kit for retrofitting into institutions or isolated, remote areas in need thereof or for off the shelf use in the home.

An exhaust line includes a housing having a wall with an opening and a baffle disposed within the opening. In certain embodiments, the exhaust line includes a divider between the wall and baffle that partially defines a mixing chamber for receiving an exhaust and a reducing agent, and partially defines a bypass chamber for receiving another portion of the exhaust. The divider defines an inlet and outlet facing respective upstream and downstream ends. The divider transfers heat from exhaust passing through the bypass chamber to the reducing agent inside the mixing chamber. In other embodiments, the baffle partially defines a first passageway substantially parallel to and offset from a center axis for delivering a portion of the exhaust to the mixing chamber, and a ramped surface partially defining a second passageway transverse to the first passageway for delivering another portion of the exhaust to the mixing chamber.

An exhaust purification system for a ship includes a main path in communication with the outside and a bypass path branched from an intermediate portion of the main path, each serving as a discharge path for an engine installed in the ship. The main path and the bypass path are provided with and opened and closed by respective fluid operated switching valves of a normally open type.

An exhaust treatment device is disclosed. The exhaust treatment device has a compact configuration that includes integrated reactant dosing, reactant mixing and contaminant removal/treatment. The mixing can be achieved at least in part by a swirl structure and contaminant removal can include NO.sub.x reduction.

A fluid mixing unit includes a cylindrical porous body partitioning a container into a first flow space and a second flow space surrounding the first flow space. A first supply port supplies a first fluid to one of the first and second flow spaces. A second supply port provided on one end side of the container in an axial direction of the cylindrical body supplies a second fluid to the other flow space. An outlet for a mixed fluid is provided on the other end side of the container to be open only to the other flow space. Closing members are provided in a plurality of stages along the axial direction to alternately close a right and a left of the other flow space as seen in the axial direction in the other flow space. A meandering flow is formed in the other flow space to create the mixed fluid.

A method for the dynamic inline mixing of a pressurized medium containing a liquid and at least one further liquid or solid constituent in a bioprocess arrangement, the liquid being merged with the at least one further liquid or solid constituent in a predefined volume ratio at an opening point to form a resulting liquid flow, the bioprocess arrangement having a pump arrangement with a first pump, the first pump being arranged in the line of the line arrangement, the first pump being designed as a rotary pump configured for the dynamic inline mixing of the medium, the first pump having a liquid inlet, which during intended operation forms the suction side of the pump, and a liquid outlet, which during intended operation forms the pressure side of the pump, and the medium being conducted through the rotary pump for the purpose of dynamic inline mixing.

A mixing device includes a fluid input portion, suitable for receiving at least one fluid to be mixed, the fluid input portion including at least one fluid input pipe; and a fluid mixing portion, communicated to the fluid input portion, the fluid mixing portion including a fluid mixing pipe, communicated to the at least one fluid input pipe; and a passive shaking deflector, arranged in the fluid mixing pipe; wherein the passive shaking deflector is driven to shake by the fluid to be mixed flowing through the passive shaking deflector. The mixing device is suitable for improving mixing efficiency in pipes without external power.

Mixing systems and methods of making mixed compositions including a first composition and a second composition. The systems and methods incorporate a fluid flow manipulation to manage an undesirable accumulation of a separable ingredient such as particles associated with the first and/or second composition as the mixed composition is further processed and packaged downstream.
