A mixing system mixes liquid adhesive and gas to create a solution. The mixing system it a manifold defining an adhesive input that receives the liquid adhesive, a gas input that receives the gas, a mixing chamber in fluid communication with the adhesive and gas inputs, an output that outputs the solution, and an output passage extending from the mixing chamber to the output. The mixing system also includes a rotor that rotates within the mixing chamber about a longitudinal axis so as to mix the solution, a motor that rotates the rotor, and a static mixer positioned within the output passage that statically mixes the solution flowing through the output passage.

An apparatus and process for preparing a water/diesel oil micro-emulsion including a diesel oil feeding unit, an emulsifying composition feeding unit, a water feeding unit, and a mixing tank in fluid communication therewith. A duct extends along main direction (X-X) and presents an inlet opening, outlet nozzle, and a cone shaped septum coaxial with respect to the main direction (X-X) and tapers towards the outlet nozzle. A plurality of holes is in the conical wall of the septum and a plurality of lamellae is arranged in the duct downstream of the septum. The plurality of lamellae creates a plurality of small chambers. Holes and the small chambers delimit a labyrinth passageway for liquid flowing through the duct towards the outlet nozzle. A batch is recirculated through the mixing tank and a conduit including a mixing device and then the fuel micro-emulsion batch is discharged.

A flow-through cavitation device having an elongated housing with an inlet and an outlet. An inner annular body and an outer annular body are concentrically and nestingly disposed in the elongated housing. The outer annular body is fixed relative to the housing and the inner annular body is rotatable about a longitudinal axis of the housing. Each annular body has a plurality of channels that pass therethrough. Rotation of the inner body relative to the outer body provides for selective alignment or misalignment of the plurality of channels to control fluid flow from the inlet to the outlet. The device may have a plurality of pairs of inner and outer annular bodies as described.

Embodiments of a Flow Conditioning System (“FCS”) of this disclosure may be used for homogenizing a fluid containing a gas phase and a liquid phase. In some embodiments the FCS may be applied to a fluid containing hydrocarbons. The FCS may be located where appropriate, including but not limited to subsea. The FCS may be used for homogenizing slug flow. In embodiments, the FCS may be composed of an outer shroud pipe section, into which a concentric perforated smaller pipe is inserted at the top. The inlet slug flow regime is changed at the shroud section whereby the slugs are broken, transitioning to well-mixed flow regimes, such as bubbly flow or continuous churn flow. The bubbly or continuous churn flow that occur in the shroud section are forced to pass through the perforations of the perforated smaller diameter pipe, which promote a more thorough mixing of the phases upstream of devices such as multiphase pumps.

A vehicle exhaust system includes a conduit defining an exhaust gas flow path extending along a center axis, and wherein the conduit includes a doser opening. An exhaust gas aftertreatment component is positioned downstream of the conduit and at least one doser is configured to inject fluid into the conduit through the doser opening. A heating element pre-heats the fluid prior to mixing with exhaust gas. A perforated pipe is positioned within the exhaust gas flow path to surround the fluid injected by the doser.

Provided in the invention is an SCR system urea mixer. The SCR system urea mixer comprises an outer pipe and an inner pipe arranged in the outer pipe. The outer pipe comprises an air inlet cone pipe (11) and an air inlet straight pipe (12) connected with the air inlet cone pipe (11). The inner pipe comprises an air inlet rectifying pipe (21) and a porous pipe (22). The porous pipe (22) is sleeved outside the air inlet rectifying pipe (21). The air inlet rectifying pipe (21) is provided with an airstream rotating mechanism (211), and the airstream rotating mechanism (211) is used for rotating exhaust gas which enters into the air inlet cone pipe (11). A rotating structure and a porous structure are used in the SCR system urea mixer, so that urea and engine exhaust are fully mixed; and the SCR system urea mixer is provided with heat preservation measures to prevent the crystallization of the urea. Moreover, the SCR system urea mixer has no complex connection installation structure, the installation is convenient, the reliability is high, and the versatility is strong. In addition, also provided in the invention is an SCR system which is installed with the SCR system urea mixer.
