    摘要： The invention relates to a device for precipitating liquid droplets from a feed gas flow containing said droplets, comprising a residence time tank (1) for preliminarily precipitating part of the liquid droplets from the feed gas flow under the effect of gravity, having an inlet line (2) for the feed gas flow into the residence time tank (1) and a discharge line (3) for the gas flow having reduced liquid droplet content and flowing out of the residence time tank (1), and tangential feeding of same to a centrifugal drop separator (4), wherein the discharge line (3) is disposed in the upper region of the residence time tank (1) and is spaced apart from the inlet line (2) to the extent that the residence time of the gas flow in the residence time tank (1) is a maximum, and having a discharge line (5) for the fluid precipitated in the residence time tank (1) on the floor of same, and wherein an axially symmetrical apparatus having a vertical longitudinal axis and circular cross section, having a jacket and hoods at the upper and lower ends of the jacket, is used as the centrifugal drop separator (4), and wherein a discharge fitting (6) for the liquid precipitated in the centrifugal drop separator (4) is disposed in the region of the bottom hood of the centrifugal drop separator (4), dimensioned such that said fitting is immersed in the liquid standing on the floor of the residence time tank (1) or in a liquid standing in a cup in the interior of the residence time tank (1), and having a gas outlet fitting (7) at the upper end of the centrifugal drop separator (4) for the gas flow further purified in the centrifugal drop separator (4),and wherein both the feeding of the gas flow having reduced liquid droplet content from the residence time tank (1) through the discharge line (3) and the draining of the liquid precipitated in the centrifugal drop separator (4) take place via the line (6) into the residence time tank (1) without the use of pumps and shutoff valves.

    摘要： The invention relates to a method for continuously cleaning a solid mixture, comprising a valuable product that can be sublimated, and components that can be sublimated more easily and with more difficulty, by fractionated sublimation/desublimation in a hot wall tube furnace (1), by supplying the solid mixture together with an inert gas flow, in which the solid mixture is dispersed by way of a dispersing organ (2), at an end of the hot wall tube furnace (1); - heating the dispersed solid mixture in the hot wall tube furnace (1) at a temperature at which the valuable product sublimates, to obtain a gas mixture comprising components that are more difficult to sublimate than the valuable product as solid particles; - passing the gas mixture, comprising components that are more difficult to sublimate than the valuable product as solid particles, over a hot gas filter (3) having a suitable pore size in order to retain the solid particles that sublimate with more difficulty than the valuable product; - cooling the gas mixture, from which the components that are more difficult to sublimate than the valuable product are separated, to a temperature at which the valuable product desublimates and at which the components sublimating more easily than the valuable product do not yet desublimate to obtain a gas mixture comprising the particle-shaped valuable product; and - separating the cleaned, particle-shaped valuable product from the cooled gas mixture.

    摘要： A process is proposed for producing nanoscale organic solid particles proceeding from the corresponding sublimable organic solid as the raw material, - in the form of particles with a mean particle diameter in the range from 1 µm to 10 mm which are dispersed in a carrier gas to obtain a dispersion which is decompressed in a convergent nozzle to which an expansion chamber is attached, and wherein - in the wall of the expansion chamber which comprises the product outlet orifice, orifices are provided in a rotationally symmetric manner about the center axis of the expansion chamber, through which orifices a secondary gas stream is injected, comprising an inert gas carrier and molecules, ions or nanoscale particles which are present in molecular dispersion therein, are different than the raw material and have a mean particle diameter less than the mean particle diameter of the product.
