Abstract:
A vortex reactor includes a reactor body having first and second ends, with one or more inlet ports coupled to the first end. The reactor is configured to form one or more vortices in a fluid passed into the reactor. The inlet port(s) may be positioned to advance a reactor fluid into the reactor body at an angle tangential to an inner surface of the reactor body, forming a vortex that advances toward the second end along the inner surface of the reactor body. A vortex induction mechanism can be disposed within the reactor to induce or augment a vortex within the reactor. The reactor includes an ultrasound-imparting device configured to generate cavitation bubbles in the reactor fluid. The fluid flow within the reactor concentrates the cavitation bubbles within the vortex, thereby providing beneficial physical and/or chemical effects, while protecting the reactor walls and other reactor components from cavitational erosion.
Abstract:
The invention relates to a cyclone (10) for mechanical separation of particles in suspension in a gas, in particular intended for a fluid catalytic cracking unit, said cyclone comprising the following elements: - a separation chamber (101), - an inlet duct (102) that opens into the chamber (101), - a gas outlet duct (103) located in the upper portion of the chamber (101) and - a particle outlet duct (104) located in the lower portion of the chamber (101), characterized in that each element of the cyclone is made of a ceramic material. The invention also relates to a fluid catalytic cracking unit equipped with at least one cyclone made of ceramic material.
Abstract:
The present invention relates to a system for remediating highly contaminated fine soilusing multiple micro hydrocyclones that includes: a mill adapted to mix contaminated soil with water and to individualizethe soil; a screen adapted to separate the soil introduced from the mill into soil having given particle sizes; a separator adapted to finely separate the soil having particle sizes of less than a given value by particle size from the soil having the given particle sizes separated through the screen; a remediating unit adapted to wash the finely separated soil introduced from the separator by particle size by means of process water for washing; and a filtering unit adapted to separately discharge the soil washed and introduced through the remediating unit and the process water for washing contained in the soil.
Abstract:
A device is disclosed for the separation of liquid-liquid phase and/or a liquid-gas phase where one or more of the phases is suspended in water and has a bubble/drop/particle size in the sub micron and micron area, and/or fine particular organic or inorganic material is present in one or more of the phases. There is also disclosed a method and a use for the device.
Abstract:
The present invention relates to a cyclone dust-collecting apparatus and a vacuum cleaner having the same. The cyclone dust-collecting apparatus includes a casing which has a dust-collecting chamber to collect dust therein, a cyclone unit which has a cyclone chamber enclosed by the dust-collecting chamber in the casing, and a cover which is removably connected to the casing to open and close the casing, and the cyclone unit has a height higher than that of the casing.
Abstract:
A method and apparatus for separating particles preferentially accelerates particles to a rotating collector, which then reliably conveys collected particles to a discharge with minimal re-entrainment of the particles in the fluid stream. The collector minimizes energy transfer to the fluid and maximizes separation under conditions of high particle loading, fine particle content, or both. The separator may be operated in any vertical, horizontal or oblique orientation, or within devices whose orientation varies over time.
Abstract:
Blending methods for adding and uniformly mixing a small fraction of relatively small particles (additives) to a bulk particulate powder of larger size than the additives. In particular, the present invention provides blending methods for adding and uniformly mixing a small percentage of flow/fluidization additives into fine powders, especially fine paint powders. The fine powder and additives are first pre-mixed for macro-scale homogeneity and then further mixed at a micro-scale (such as with a screen mixing process) for micro-scale homogeneity. With these methods, optimum dispersions and maximum functionalities of additives can be obtained and the disadvantages caused by severe agglomerates of additives can be avoided.
