The invention pertains to a spray/gas mixer, comprising: a main body having a circumferential wall with a first longitudinal axis (A) and extending from a first end to a second end, the first end defining an inlet opening, the second end defining an outlet opening; a divider baffle inside the interior; a swirl duct within the interior along a second longitudinal axis (B), having one end adjacent to the wall and a second end extending to the divider baffle; an injector orifice at the first end of the swirl duct; a swirl promoting means; and a restrictor arrangement. The swirl promoting means is arranged between the divider baffle and the restrictor arrangement, such that gas passing through the swirl promoting means is swirled around the first longitudinal axis (A) before passing through the restrictor. The restrictor arrangement is disposed between the swirl promoting means and the second end, forcing gas reaching it from an upstream side away from a peripheral region of the interior towards a center axis of the main body.

The present invention is a composting bioreactor system that continually receives biodegradable solid wastes, waste waters and exhaust gases, automatically recycles the biodegradable wastes into nutrients and heat energy, and automatically supplies the nutrients and heat into an integrated hydroponic or aquaponic system. This invention together with integrated food growing system may be installed onsite such as balconies, backyards and premises of restaurants and food factories etc. therefore may lead to zero mileage targets both for recycling wastes and for supplying foods. This invention integrates composting process and aquaponic technology together and may establish a closed-loop recirculation of both water and gases therefore upgrades aquaponics into compoponics. A compoponic system has both soil and soilless growing beds and mimics nature recirculating nutrients, carbon and energy among human being, animals, microorganisms and plants by way of photosynthesis, slow burning by cellular respiration and burning by combustion.

A vehicle exhaust system includes an inlet module configured to receive engine exhaust gas and a mixer housing defining an internal cavity that receives engine exhaust gas from the inlet module. An injection component is positioned within the internal cavity and has a fluid inlet and a fluid outlet to direct injected fluid into the internal cavity to mix with the engine exhaust gas. The injection component defines an injection axis and includes an inner structure defining an inner gas flow path and an outer structure defining an outer gas flow path that is between the inner and outer structures and radially outward of the inner gas flow path to improve mixing at the fluid outlet. An outlet module is configured to direct a mixture of engine exhaust gas and fluid to a downstream exhaust component.

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.

A vehicle exhaust component assembly includes an inlet module configured to receive engine exhaust gas, a mixer housing defining an internal cavity that receives engine exhaust gas from the inlet module, and an injection component defining an injection axis and positioned within the internal cavity. The injection component has a fluid inlet and a fluid outlet to direct injected fluid into the internal cavity to mix with the engine exhaust gas. The injection component comprises at least a first curved sheet and a second curved sheet that cooperate with each other to surround the injection axis, wherein the second curved sheet is offset from the first curved sheet by a radial gap to create a swirling gas flow within the injection component to mix with fluid injected via the fluid inlet. An outlet module directs a mixture of engine exhaust gas and fluid to a downstream exhaust component.

An apparatus for aftertreatment of exhaust gas includes a housing configured to define an inner cavity; an exhaust inlet arranged to the housing for entering exhaust gas flow to the inner cavity; a mixer unit arranged in the inner cavity to dispense a reactant to the exhaust gas flow; a mixing device, located downstream of the mixer unit, to evenly mix the reactant to the exhaust gas flow. The mixing device includes: a toroidal cylinder to receive the exhaust gas flow from the mixer unit via a solid tubular element, wherein the solid tubular element is in a centric manner to a first base of the toroidal cylinder for guiding the exhaust gas flow led into the toroidal cylinder to swirl inside the toroidal cylinder; and an exhaust outlet arranged to a curved side of the toroidal cylinder, to exit the exhaust gas flow from the mixing device.

The present invention provides a carbon dioxide supplier capable of forming a swirl flow of a mixture gas and evenly distributing the mixture gas through porous grating hole of a catalyst for catalyst combustion to maintain uniform temperature throughout the entire volume of the catalyst to maintain stable combustion of carbon. The carbon dioxide supplier comprises: a mixture gas supply unit supplying a mixture gas of air and fuel; a combustion unit combusting the mixture gas supplied from the mixture gas supply unit; and a swirl forming unit 40 extending between the mixture gas supply unit 30 and the combustion unit 50 in anteroposterior direction, the swirl forming unit 40 swirl-flowing the mixture gas introduced into a rear portion thereof from the mixture gas supply unit 30 to the combustion unit 50 provided at a front portion thereof.

A mixing device may define a mixing chamber including a vortex mixing portion, a primary gas path along which a first gas stream moves to the vortex mixing portion, and a secondary gas path along which a second gas stream moves to the vortex mixing portion. The mixing device may have a mixer body, an outer gas guide positioned in the mixer body to guide the second gas stream to the vortex mixing portion, and an inner gas guide at least partially positioned in the mixer body to guide the first gas stream to the vortex mixing portion. A portion of the inner gas guide may be positioned in the outer gas guide to form an annular gap between the gas guides to define the secondary gas path about the primary gas path to create a vortex of the first and second gas streams in the vortex mixing portion.
