Removing dusts from gases - by subjecting stream of dust-laden gas and atomised liq. to direction change in system of vanes and dampers, maximising mixing (DK 31.3.80)

摘要

A process and appts. comprises subjecting the stream of dust-contg. gas and liq. to a large change in direction, pref. 90 degrees, by means of a system of vanes and of turning dampers by means of which the section of the flow passage can be regulated. The gas and its content of liq. drops are obliged to pass through adjustable openings existing between the turning dampers and the vanes so that it becomes intimately mixed with the wash liq. retained by the guiding vanes. The process and appts. are partic. for dusts coming from a drying installation, the quantity of which per unit of time can vary greatly. The appts. has the necessary flexibility of operation for satisfactory purificn. in all circumstances. It utilises the loss of energy produced by the throttling, necessary when the gas flow has to be reduced, to allow a better washing of the gas to be obtd..
