Claim Text:
1. A method for separation of acid components, dust, and tar from hot gases of gasification systems, comprising the following steps: providing a cyclone and a filter space equipped with filter cartridges within a common vessel, the cyclone and filter space being arranged one on top of the other in the direction of gravity and being separated by a partition configured as a funnel-shaped bottom, wherein a central pipe of the cyclone is passed into the filter space through the funnel shaped bottom, passing the hot gases that exit from gasification, at a temperature above 700° C., with additives, to desulfurization and subsequently to the combined cyclone and filter cartridges in the common vessel, feeding micro-dust from the funnel shaped bottom through feed elements to a down-pipe positioned in the central pipe, the down pipe being smaller in diameter than the central pipe, and drawing off the gases behind the filter cartridges, for further use.
