Abstract: A droplet separator for removing drops of liquid from a gas stream comprises a stack of corrugated plates each of which is generally planar but has a plurality of corrugations formed by alternating crests and troughs of given wavelength and amplitude. The troughs of adjacent plates register with one another to define flow passages for the gas stream extending generally in a flow direction between the inlet and outlet sides of the stack. The crests of adjacent plates contact one another between the flow passages and each of the flow passages is formed with at least two bends in the plate plane effecting direction change in the gas flowing therethrough. The corrugations are all of trapezoidal cross section.

Abstract: An apparatus for the separation of liquid droplets or fine-particulate solids from a gas stream entraining same in which a plurality of geometrically identical separator plates define flow passages between them for the gas. The plates are formed with corrugations and the crests or troughs of the corrugations are provided with phase-separating chambers open in the direction of the oncoming gas stream. The gas stream entering the gaps at the inlet sides of the phase-separating chambers precipitates the liquid or solids which are conducted downwardly along chambers formed by the phase-separating chambers which are oriented vertically. According to the invention, the successive corrugations (i.e. successive crests or troughs) of each separator plate in the direction of flow are provided with decreasing heights (measured perpendicularly to a median plane through the plate) and the successive corrugations are of decreasing width in the direction of flow of the gas.

Abstract: A washing tower for the washing of gases containing particulates comprises a packed bed through which the gases pass upwardly and jets for spraying water into the gas as it rises within the tower. A preferably chevron-shaped coarse droplet separator is provided above the spray nozzles and the bed and consists of upper and lower arrays of oppositely inclined plates. Further spray nozzles are provided above the coarse separator and above these spray nozzles is disposed a fine-particle separator of the baffle type through which the gas is deflected in opposite directions and with passages of smaller width than those of the coarse particle separator. The gas emerges from the upper end of the tower.
