Discontinuously operated desublimator having at least one flow disruptor

Abstract

The invention relates to a discontinuously operated desublimator (1) for removing at least one gas component to be desublimated from a gas mixture flow, which desublimator comprises: a housing wall (7); an inlet (2) in the housing wall (7) for supplying the gas mixture flow into the desublimator (1); an outlet (6) in the housing wall (7) for discharging the treated gas mixture flow from the desublimator (1); a desublimation zone (4) with temperature-controllable flow channel walls, wherein the flow channel walls are temperature-controllable in such a way that during a loading process the at least one gas component to be desublimated is desublimated at the flow channel walls and that during a subsequent melting process the at least one gas component desublimated in the loading process melts at the flow channel walls; a gas entry distribution chamber (3), which is located between the inlet (2) and the desublimation zone (4); and a gas exit distribution chamber (5), which is located between the outlet (6) and the desublimation zone (4). According to the invention, a flow disruptor (8) is located in the gas entry distribution chamber (3) for uniformly distributing the gas mixture flow through the flow channels that result from the flow channel walls of the desublimation zone (4), the geometric centre of gravity of which flow disruption has a spacing (AT) from the geometric centre of gravity of the inlet surface (9) in the range of 0.2*D to 10.0*D, preferably in the range of 0.5*D to 3.0*D, wherein D corresponds to the equivalent diameter of a circle having the same area as the inlet surface (9) and the spacing (AT) is measured along the normal vector (nE) of the inlet surface (9). The invention also relates to a method for operating a desublimator (1) according to the invention.
