Universal/scrubber/precipitator for scrubbing smoke

Abstract

A universal/scrubber/precipitator comprises at least one, or a plurality of rolls or circular cylinders concentric and rotatable in one direction about their common axis. The rolls are perforate with perforations less each in span than the span supported by the surface tension of the liquid in a liquid bath in which the drums are partially immersed. Each roll has a plurality of cups at least one each 180 degrees about the roll, extending from one axial end to the other. The rolls are sealed at their ends to prevent leakage of smoke, and also at the top of a main deceleration chamber having a plurality of deceleration chambers and a plurality of deflectors, and a condensation chamber. Smoke is propelled from the inlet deceleration chamber through the perforations, and then to the other deceleration chambers, as the roll rotates, the cups being faced to pick up liquid from the liquid bath and spill or discharge liquid as they reach the top, and ascending water curtains are formed as the liquid is splashed against buffers on each side of the roll. Therefore, the smoke and any other particles are forced to pass through the perforations of all the drums to the interior of the innermost drum and from there through the perforations of all the drums to the outermost drum and into the outlet deceleration chamber. Thus, the smoke is washed and cleaned as it passes through the wetted perforations. The perforations should have less of a span than will be supported by the surface tension of the liquid, so that the perforations are closed with liquid if they are opened by the passage of smoke.
