摘要:
The present invention provides apparatuses and methods for continuously separating particles of interest from a heterogenous particle population. the heterogeneity can be based on, for example, magnetic susceptibility, particle size, thermal diffusion, phase solubility, and combinations of the preceding. Based on the heterogeneity, a separation force capable of exploiting the separand (i.e., particles subject to the separation process) is provided. The various embodiments of the present invention preferably employ an annular separation channel, appropriate separation force and flow compartments. In a first embodiment, an annular separation channel having semi-permeable inner and outer cylindrical walls is used to generate lateral convection forces. In a second embodiment of the present invention, an annular separation chanel having heat conductive inner and outer cylindrical walls is used to generate thermal diffusion forces. In a third embodiment, an annular separation channel having non-permeable inner and outer cylindrical walls is used to generate a solubility difference separation force based on solubility coefficient differences between phases of flow compartments. In a fourth embodiment, an annular separation channel having electrically conductive inner and outer cylindrical walls is used to generate an electrophoretic separation force. In a fifth embodiment, an annular separation channel having electrically conductive inner and outer cylindrical walls is used to generate a dielectrophoretic separation force. Yet other embodiments of the present invention provide for the combination of separation forces including lateral convection, thermal diffusion, solubility difference, electrophoretic, dielectrophoretic, and magnetic separation forces.

摘要:
Die Erfindung bezieht sich auf ein Verfahren zur Abscheidung von Feinstpartikeln aus dem Abgas von Brennkraftmaschinen. Zur Abscheidung von Rußpartikeln bedient man sich gewöhnlicher Filter, welche die negative Eigenschaft haben, daß sie durch Drosselwirkung zu einem spürbaren Mehrverbrauch an Treibstoff führen. Demgegenüber werden Rußpartikel erfindungsgemäß filterlos abgeschieden. Die Abscheidung erfolgt dabei durch Nutzbarmachung der Effekte der Thermophorese, der Konvektion, und der Diffusion, oder durch eine Kombination dieser drei Effekte. Der Drosselverlust bei dieser Art der Abscheidung ist wesentlich geringer. Die Oxidation der abgeschiedenen Rußpartikel erfolgt durch NO 2 , welches in einem vorgeschalteten Katalysator (2) durch katalytische Oxidation von NO mittels des im Abgas enthaltenen Restsauerstoffes entsteht.
摘要:
A system for separating constituents from a base material (20) using RF energy which is coupled to a reaction chamber (18) by way of a windowless transmission line (12). By eliminating the need for a window, traditional limitations placed on the maximum power delivered to the resonating cavity (34) are eliminated. Thus, the only practical limitation on the RF energy which can be delivered to the resonating cavity (34) the ability of the RF energy source (10) to produce that energy and the ability of the resonating cavity (34) to manage that energy.
