摘要： Dosing and mixing exhaust gas includes directing exhaust gas towards a periphery of a mixing tube that is configured to direct the exhaust gas to flow around and through the mixing tube to effectively mix and dose exhaust gas within a relatively small area. Some mixing tubes include a slotted region and a non-slotted region. Some mixing tubes include a louvered region and a non-louvered region. Some mixing tubes are offset within a mixing region of a housing.

摘要： An exhaust treatment arrangement includes a mixing assembly disposed between first and second substrates; and an injection mounting location disposed at the mixing assembly. The mixing assembly includes a mixing arrangement configured to direct exhaust flow exiting the first substrate in a swirling configuration, a restricting member defining a restricted passage, and optionally a dispersing member configured to even out the exhaust flow.

摘要： A system for separating a solvent includes a first mixing tank comprising a waste solvent feed and a reactant feed; a first filter comprising a nanofiltration membrane; a distillation column or an evaporator; a condenser or cooler; and a pervaporation membrane. A method for separating a solvent includes mixing a waste solvent with a reactant to cause precipitation or complexing and forming a mixture; filtering the mixture using a nanofiltration membrane and forming a permeate; distilling or evaporating the permeate to form a concentrated solvent; condensing or cooling the concentrated solvent to below a boiling point of solvents in the concentrated solvent; and filtering the concentrated solvent using pervaporation to form a purified solvent. The system and method may be used to separate and purify a solvent without creating thermal degradation products.

摘要： A dosing and mixing arrangement including an exhaust conduit defining a central axis; a mixing conduit positioned within the exhaust conduit; a dispersing arrangement (e.g., a mesh) disposed at the upstream end of the mixing conduit; an injector coupled to the exhaust conduit and configured to direct reactants into the exhaust conduit towards the mesh; and an annular bypass defined between the mixing conduit and the exhaust conduit for allowing exhaust to bypass the upstream end of the mixing conduit and to enter the mixing conduit downstream of the mesh.

摘要： Embodiments herein relate to indoor air quality monitoring systems and related methods. In an embodiment an indoor air quality monitoring system is included having a control circuit, a memory circuit, and a sensor channel interface. The system can be configured to store a model set of data reflecting information on air quality determining features within a physical indoor environment, receive sensor data regarding air quality at discrete points within the physical indoor environment, and evaluate the sensor data regarding air quality and perform operations to generate one or more outputs relating to air quality within the physical indoor environment. Other embodiments are also included herein.

摘要： An aftertreatment device includes flow guides disposed within a dosing conduit. Exhaust enters through a perforated region of the dosing conduit and passes through the flow guides. The flow guides induce swirling or other turbulence to mix injected reactant with the exhaust gas. Various types of flow guides include cantilevered vanes, guide passageways, and louvered openings of a second conduit. Some types of flow guides induce localized mixing to inhibit deposit formation at the doser mounting unit. Other types of flow guides induce mixing downstream of the dosing conduit.
