An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.

Apparatus and method for mixing reductant in an exhaust gas flow using virtual interception. Embodiments include an exhaust gas and reductant mixer comprising a body, a first flow device, and a reductant entry port. The body defines an exhaust gas flow path having a central portion. The first flow device swirls the exhaust gas in a circumferential direction with respect to the gas flow path. The reductant entry port introduces the reductant into the gas flow path at a location downstream from the first flow device and in an introduction direction (1) offset from the central portion, and (2) opposite the circumferential direction.

A static mixer for mixing fluid flow in a pipeline includes a body having a plurality of slots through the body, the slots being angled with respect to an axis passing through a center of the body. A plurality of arms extends from an outer edge of the body towards a center of the body, each arm having a flat surface on a first side of the body and angled sides along at least a portion thereof extending to a second side of the body. The plurality of slots includes at least one concentric ring of slots.

A system, method, and apparatus for oxygenation of a source of water, to increase the dissolved oxygen content of water. Aspects of the present invention harnesses and directs the power of water flowing through the system to extract oxygen present in air, rather than relying on the injection of gas or using other mechanical means. The water oxygenator is formed as an elongate cylindrical tube having a water inlet at a first end, a water outlet at a second end, and an air inlet proximal to the first end. The elongate cylindrical tube has an outer sidewall defining a mixing chamber within an interior cavity of the water oxygenator. The mixing chamber includes a plurality of baffles that are disposed in a spaced apart relation along a longitudinal length of the interior cavity.

One aspect of the invention relates to a method comprising a single-stage conversion of an atmospheric pollutant, such as NO, NO.sub.2 and/or SO.sub.x in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO.sub.2.sup.0), wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

The present application provides a dispensing nozzle assembly for mixing a first fluid and a second fluid. The dispensing nozzle assembly may include a target assembly with a number of fins and a number of channels and a static mixer positioned about the fins.

A mixing device and a vapor compression system incorporating a mixing device are provided. The vapor compression system includes a suction line, at least two compressors, and at least one mixing device that is predominantly open (e.g., i.e., include at least a certain percentage, such as seventy percent (70%), of voids/openings). The suction line is used for transferring a working fluid made up of a mixture of a refrigerant and an oil. The suction line includes at least one inlet (e.g., for receiving the working fluid) and at least one outlet (e.g., for distributing the working fluid). The vapor compression system include a first compressor fluidly connected to a first outlet and a second compressor fluidly connected to a second outlet. At least one mixing device is disposed within the suction line (e.g., to increase an internal turbulence of the working fluid).

A fluid processing system includes a fluid processing unit and a tubing arrangement providing fluid flow to and from the fluid processing unit. The tubing arrangement includes one or more flow cells and the fluid processing unit is selected from a unit comprising a single use tangential flow filtration mobile skid and a unit comprising a device for chromatographic separation. Each one of the flow cells includes a body having an inlet and an outlet and a fluid flow channel extending from the inlet to the outlet of the body.

A mixer duct for mixing of a turbulent flow includes an inlet, an outlet in fluid communication with the inlet, and at least one static mixer element located between the inlet and the outlet. The at least one static mixer element includes at least two at least substantially coplanar plate-like segments spaced apart by a substantially longitudinal gap. Each segment is attached to a duct wall and comprises at least two free edges, with one free edge being a leading edge and the other free edge adjacent to the longitudinal gap. The at least two segments are inclined relative to a duct axis so that their leading edge is oriented up-stream in the mixer duct and substantially perpendicular to a direction of a main fluid flow.

A device to be installed in a pipeline, characterized by at least one static mixer and at least one pre-mixer arranged in a sleeve, wherein said at least one static mixer is characterized by: a body having a plurality of slots through the body, said slots having one or more sides that are angled with respect to an axis passing through a center of the body; a plurality of arms extending from an outer edge of the body towards a center of the body, wherein the plurality of slots comprising at least one concentric ring of slots.
