Abstract
A drop trap for a gas scrubbing plant, the trap having a plurality of parallel spaced apart corrugated plates forming channels through which gas flows and baffles at the downstream side of the corrugated plates to impart a downward velocity to liquid particles entrained in the gas flowing through the channels. Further baffles may be located at the upstream side of the corrugated plates to deflect the liquid particles downwardly to flow over the corrugated plates as they are separated from the gas as it passes through the channels. A method is also disclosed of rinsing the corrugated plates by intermittently spraying a predetermined quantity of liquid over the upstream side of the plates.
Claims21
An apparatus for purification of a stream of gas, comprising a gas inlet, a gas outlet, and, therebetween, at least one scrubbing stage and at least one drop trap downstream of the said stage for separating the scrubbing liquid from the gas, the drop trap comprising an entry and an exit for the gas and a plurality of vertically spaced corrugated separator plates extending substantially parallel to one another and defining horizontal gas flow passages therebetween which extend from the entry to the exit and through which the gas is required to flow, and flow guide means disposed on the exit of the drop trap substantially outside the separator plates and extending across the latter to transmit a downwardly directed velocity component to the gas flow inside the drop trap at least near its exit.
