In an axial jet mill, an internal structure having a cylindrical outer surface is positioned within a housing to establish a raceway for the circulating movement of gas and solid material while maintaining the gas and solid material in close proximity to the outlets of gas nozzles distributed around the perimeter of the raceway. Solid material enters the jet mill though a bottom wall of the housing and passes into the raceway though gaps between the bottom of the internal structure and a bottom wall of the housing. Particles and gas exit the jet mill though a central outlet in the housing located above the internal structure.

A device and method for preparing a nano-fragmented product. A polysaccharide slurry is circulated in a polysaccharide supply path (3) via a chamber (2). Specifically, using a pump (8), the polysaccharide slurry in a tank (7) is circulated in a circulation path (9) which is formed using a vinyl hose, a rubber hose or the like. On the other hand, another slurry than the polysaccharide slurry is circulated through a second fluid medium supply path (4) as another circulation path via the chamber (2). Specifically, using a pump (11), the slurry other than the polysaccharide slurry in a tank (10) is caused to pass through a heat exchanger (12) and a plunger (13) and thereby circulate in the other circulation path. The slurry other than the polysaccharide slurry circulated in the second fluid medium supply path (4) is orifice-injected against the polysaccharide slurry circulated in the polysaccharide slurry supply path (3) and flowing through the chamber (2).

The present invention discloses a device for pulverization and explosion suppression of low carbon gas hydrate (LCGH). A feeding chamber connects with a pulverizing chamber, and the chambers communicate through a feed port. A pulverizing air pipe and the feeding chamber communicate through a feeding air pipe; two ends of a venturi connect with an entrainment chamber and a disperser respectively; and a gas-solid separation membrane (GSSM) is disposed on a discharging port and used for preventing LCGH powder from entering the entrainment chamber from the pulverizing chamber. When an explosion is triggered, the GSSM is opened to make the LCGH powder enter the entrainment chamber. The device can store and pulverize the LCGH and spray LCGH powder to achieve combustion and explosion suppression.

The inlet apertures (2, 4) are configured along the full height of a side wall of the cylinder-like housing (1), moreover, the first inlet aperture (2) is oriented at a lesser angle relative to the radius of the housing (1) than at least two secondary apertures (4) and is opposed to the latter in terms of the direction of delivery of the energy carrier about the axis of the housing. Vortex generators (3) are disposed next to the secondary inlet apertures (4).

A spiral jet mill for comminuting and classifying grinding material, including at least one process chamber, wherein this at least one process chamber is enclosed by a housing, at least one grinding material feeding, which leads into the at least one process chamber, at least two grinding nozzles, a fine material outlet, which is radially enclosed by a separator wheel, wherein at least one discharge nozzle is assigned to the process chamber.

The proposed multifunctional hydrodynamic vortex type reactor includesa housing having curvilinear inner sidewalls,a base attached to the housing, an inverse taper narrowing downward and attached to the top of housing,a supporting tube passing at least through the housing and base,a set of washers tapered downward and mounted on an outer surface of the supporting tube such that outer upper edges of the set of washers and the inner sidewalls form predetermined gaps therebetween, anda number of inlets tangentially attached to the base for introducing, under external pressure, a solid substance and a liquid (or a suspension of their mixture) thereinto, forming a circulating flow therein. The flow forms a high speed bypassing cavitation zone and, changing its direction at the inverse taper, forms a vortex cavitation zone, providing for mixing and grinding the substance up to nanoscale sizes. Methods for intensifying cavitation are also provided.

Various wear resistance designs may be applied to a reactor configured to facilitate chemical reactions, and/or comminution using shockwaves created in a supersonic gaseous vortex. The reactor may include a rigid chamber having a substantially circular cross-section. A first gas inlet may be configured to introduce a high-velocity gas stream into the chamber. A first replaceable wear part may be disposed in the chamber to absorb wear impact caused by the gas stream. In some implementations, the first replaceable wear part may be a cylindrical rod continuously fed into the chamber. In some implementations, the first replaceable wear part may be coated with, or composed of, a catalytic material, and/or may be electrically isolated from the rest of the reactor. In some implementations, a second gas inlet may be disposed to steer the gas stream to a desired area within the chamber to even out the wear impact.

An appliance is disclosed for the size-reduction and drying of waste material. An essentially funnel-shaped vessel has a cylindrical attachment, on which at least two air inlets for introducing compressed air (L) are arranged in a manner distributed over a periphery of the cylindrical attachment, with an exit opening for size-reduced material (G) on a base of the funnel-like vessel.
