INJECTOR SPRAY PROTECTOR
A vehicle exhaust system includes an injector assembly having an injector mount configured to mount an injector to an exhaust component. The injector mount includes a spray opening surrounding a spray axis. An injector housing extends from an inlet end that receives exhaust gases to an outlet end. The inlet end defines a planar area that is transverse to the spray axis. A spray protector extends axially from the injector mount to break the planar area. A vehicle exhaust component assembly comprising a mixer with the injector assembly and a method for injecting a fluid into an exhaust component using the injector assembly are also disclosed.
Dispensing system for mixture of two components and static mixing nozzle therefor
Dispensing system for dispensing a mixture of a first component and a second component, the dispensing system comprising: (i) a dispensing gun comprising an inlet body with a first passage for feeding in the first component under pressure and a second passage for feeding in the second component under pressure, the first and second passages respectively comprising a closable first outlet and a closable second outlet, which may be operable by means of a handle or trigger of the dispensing gun; (ii) a static mixing nozzle, detachably connectable to the outlets of the body and provided for mixing and dispensing the components, the static mixing nozzle comprising a first section containing a first chamber and a second chamber for conducting the first and second component respectively and a second section, subsequent to the first section (in forwards flow direction), containing a mixing chamber with static mixing elements which promote mixing the first and second components and conducting the mixture to a nozzle tip serving as an outlet for the mixture. According to the invention, at least one of the first and second chambers of the static mixing nozzle contains a series of static backflow prevention elements, arranged for hindering backflow of the respective component within the respective chamber.
Systems and methods for mixing exhaust gases and reductant in an aftertreatment system
A multi-stage mixer includes a multi-stage mixer inlet, a multi-stage mixer outlet, a first flow device, and a second flow device. The multi-stage mixer inlet is configured to receive exhaust gas. The multi-stage mixer outlet is configured to provide the exhaust gas to a catalyst. The first flow device is configured to receive the exhaust gas from the multi-stage mixer inlet and to receive reductant such that the reductant is partially mixed with the exhaust gas within the first flow device. The first flow device includes a plurality of main vanes and a plurality of main vane apertures. The plurality of main vane apertures is interspaced between the plurality of main vanes. The plurality of main vane apertures is configured to receive the exhaust gas and to cooperate with the plurality of main vanes to provide the exhaust gas from the first flow device with a swirl flow.
Mixing Device
A mixer assembly comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The tubular housing defines a longitudinal axis along which exhaust enters the housing. The reductant inlet is positioned on a first side of the tubular housing. An upstream element covers approximately one-half of the cross sectional area of the enhaust gas inlet and is positioned upstream of the reductant inlet. An upstream surface of the upstream mixing element directs exhaust gas flow transversly toward the reductant inlet. A downstream mixing element along with the upstream mixing element at least partially defines a reductant receiving duct in which injected reductant and exhaust gas mix.
Plural component spray gun system
A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.
Water processing apparatus
A water processing system is provided for processing or conditioning water to be distributed to a downstream function or system. The system includes a water processor with a conditioning element disposed inside a housing between an inlet and outlet of the housing. The conditioning element includes a series of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plates may have different configurations of apertures. Optionally, a mixer injector introduces a gas, in the form of gas bubbles, into the water flow upstream of the water processor. The injector introduces additional gas volume in the form of relatively large bubbles, which are subsequently split into smaller bubbles (including nano-bubbles) in the water processor.
PLURAL COMPONENT SPRAY GUN SYSTEM
A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.
STATIC MIXER RESISTANT TO HEAT, CORROSION AND DISSOLUTION
The present disclosure relates to a mixer device having a housing including at least first and second adjacent mixing cells (2, 3), each cell (2, 3) including a fluid inlet opening (21, 31) and a fluid outlet opening (22, 32), the inlet opening being offset from the outlet opening so that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell via a connecting channel.
