Abstract: The invention relates to a centrifugal droplet separator for separating liquid droplets from a feed gas flow containing said droplets, having a vertical longitudinal axis and a circular cross-section, having a shell (1) and hoods (2) on the upper and lower ends of the shell (1), having a tangential supply (3) of the feed gas flow containing the liquid droplets on the shell (1) and having 10 outlet socket (4) for the liquid separated in the centrifugal droplet separator in the region of the lower hood (2) and having a gas outlet socket (7) for the gas flow purified in the centrifugal droplet separator in the region of the lower hood (2), which is characterized in that there are two, three or more inlet openings (9) arranged symmetrically on the circumference of the upper hood (2) for a tangential 15 supply of flushing fluid in the same direction as the supply of the feed gas flow containing the liquid droplets.

Abstract: 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.

Abstract: The invention relates to a method for producing chlorine by gas phase oxidation of hydrogen chloride on a heterogeneous, particulate catalyzer in a fluidized-bed reactor, obtaining a product gas mixture that is freed of any carried catalyzer particles in cyclones (1) disposed in the upper region of the fluidized-bed reactor, comprising a cylindrical upper part (2) having a tangential or spiral inlet (3) for the product gas mixture and narrowing at the lower end thereof via a conical part (4) into a cyclone downpipe (5), and a central immersion pipe (6) in the upper region of the cyclone (1) for diverting the product gas mixture freed of the carried catalyzer particles, characterized in that one to seven cascades of two to five cyclones each connected in series are used, wherein the cyclones (1) of each cascade, except for the cyclone (1) first permeated, which is designed that approximately 90 to 99% by weight of the carried catalyst particles are precipitated, each comprise a trickle valve (7) at the lower end of the cyclone downpipe (5) comprising an angled pipe terminator (8) and a loose flap valve (9) suspended at an angle α to the vertical, wherein the angle α and the weight of the flap valve (9) are designed so that the torque of the flap valve (9) based on the diameter of the outlet opening out of the angled pipe terminator (8) is in the range of 2 to 300 N/m
