A method for preparing an insulating product based on wool includes an aeration step inside a device, the device including a chamber and at least one structure capable of generating a turbulent gaseous flow, during the aeration step. A stream of carrier gas is introduced into the chamber and a wool in the form of nodules or flakes is subjected to the turbulent flow of this carrier gas with entrainment in one sense in a direction A and in the opposite sense in a direction B that is the opposite to the direction A so that within the chamber there is at least in one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.

A device may include a chamber configured to aerate a wool suitable for an insulating product; an air jet configured to introduce a turbulent gaseous flow into the chamber and entrain the wool within the chamber an entrainment of the wool in one sense in a direction A, and in a direction B that is the opposite of the direction A, such that within the chamber there is at least one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.

An apparatus for the treatment of powder, grain, paste products or the like has a treatment chamber provided with a loading mouth for at least one powder, grain or similar product and with a discharge mouth for the product; a closing cap for the discharge mouth; and at least one annular manifold, which is obtained in the discharge mouth or in the closing cap and communicates with the outside through an annular outlet channel configured to feed a compressed air flow along an inner surface of the discharge mouth and/or along an outer surface of the closing cap.

A disturbance device has two jet mixers, which are oppositely disposed in the horizontal direction; a mixing chamber, which is connected between the two jet mixers; and mixing pipes, which are connected below the mixing chamber. The mixing pipes comprise: a central pipe, which is a vertical straight pipe; multiple helical pipes, which are wound in multiple layers and provided outside the central pipe, the diameters of the multiple helical pipes gradually increasing from the inner to outer layers, and multiple flow deflector assemblies being provided at intervals in each helical pipe; and an outer sleeve, which is a straight pipe, the outer sleeve being sleeved outside the outermost helical pipe. A continuous gas separation system combines a hydrate-based process and a reverse osmosis process, using the disturbance device, enables continuous gas separation.

A mixing chamber for use in a beverage carbonation system is provided. In one embodiment, the carbonation mixing chamber includes a housing, a fluid inlet pathway, a gas inlet pathway, and an outlet pathway. The housing may have an inner chamber, and the fluid inlet pathway can be configured to extend into the inner chamber of the housing and receive fluid from a fluid source. The gas inlet pathway can be configured to extend into the inner chamber of the housing and can be configured to receive gas from a gas source. The gas inlet pathway can include a plurality of nozzles positioned within the inner chamber and configured to direct gas in a plurality of directions that differ from one another. The outlet pathway can be configured to dispense a mixture of fluid and gas from the inner chamber.

There is provided an oxygenation assembly and an aquaculture diffuser thereof. The diffuser includes a plurality of circumferentially spaced-apart gas injection ports. The diffuser includes a plurality of circumferentially spaced-apart and axially-extending passageways. Each axially-extending passageway aligns with a respective one of the gas injection ports. Each axially-extending passageway is shaped to receive a mixture of water and oxygen-containing gas therethrough. The diffuser includes a plurality of circumferentially spaced-apart and radially outwardly-extending passageways. Each radially-extending passageway is in fluid communication with a respective one of the axially-extending passageways. Each said passageway may include an intensifier or constriction between proximal and distal end portions thereof. The diffuser may include a plurality of circumferentially spaced-apart expansion chambers each positioned between and in fluid communication with a respective said axially-extending passageway and a corresponding respective said radially-extending passageway. The diffuser is shaped to induce a homogeneous ramping turbulent kinetic energy (TKE) dissipation field.
