DEVICE FOR PRECIPITATING LIQUID DROPLETS FROM A FEED GAS FLOW CONTAINING SAID DROPLETS AND HAVING A LIQUID CONTENT OF 101 LIQUID/M³ OF FEED GAS

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.
