Abstract: The invention relates to a device for humidifying the intake air of internal combustion engines that are equipped with a turbocharger. The device comprises a humidifying unit (14, 16) through which the intake air and humidifying liquid flow and come into contact with one another. The humidifying unit is arranged upstream from the compressor (6) of the turbocharger in the direction of flow of the intake air. A heat exchanger (13, 15), which serves to pre-heat the intake air and through which the atmospheric intake air flows, is located upstream from the humidifying unit in the flow path of the intake air. Said heat exchanger is connected to a liquid circuit (11, 21) with which the humidified intake air that is compressed by the compressor and supplied to the internal combustion engine is cooled by another heat exchanger (9).

Abstract: Described is a mist collector arrangement for gas washers etc. having in gas flow direction a downstream and an upstream mist collector layer. The profiles of the successively arranged rows of the downstream and upstream mist collector layers are positioned oppositely with respect to one another in gas flow direction. In this manner an improved cleaning effect is obtained when periodically rinsing the mist collectors.

Abstract: A uniflow cyclone separator for the removal of solid or liquid particles from a gas stream comprises a housing forming a flow path with a central body from which swirl-generating vanes extend outwardly. The housing is surrounded by a collection chamber and the vanes are formed with collection edges and channels which open through the housing wall into this chamber. Downstream of the swirl-generating vanes are outlet slots which are pitched substantially transverse to the cyclonic stream 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.

Abstract: An apparatus for removing mist from a flow of gas comprises a plurality of partitioning walls and a plurality of trough-shaped separator plates, of generally V-shape, arranged to define a plurality of tortuous rectangular channels through which a gas can flow from a gas inlet portion to a gas outlet portion. Each separator plate comprises a plurality of chevron shaped directing grooves centrally disposed between each pair of partitioning walls and flat run off zones between the chevron shaped directing grooves and the partitioning walls.Each plate comprises a plurality of successive generally planar pieces arranged to form a V-shaped trough.
