Abstract
In a compressed air purification apparatus for motor vehicles, compressed air under static pressure in a pressure conduit (3) is firstly freed of impurities such as hydrocarbon compounds and oil products and subsequently dried. To ensure effective freeing of the compressed air of impurities and water vapour and provide a compressed air purification apparatus which can be used with simple means in motor vehicles, the invention provides for the compressed air being brought, before purification, to such a temperature that the gaseous impurities in the compressed air are condensed and the water present in the compressed air is dissolved as vapour.
Claims15
A method for processing compressed air for one or more pneumatic consumers, wherein the compressed air in a pressure line (3) is firstly purified of contaminants, such as hydrocarbon compounds and oil products, and subsequently dried, characterized in that the compressed air, before the purification for the removal of contaminants, is brought to a temperature (T-Act) which is such that the contaminants present in gaseous form condense and the water mass contained in the compressed air is dissolved as steam.
The method as claimed in one of the preceding claims, characterized in that the compressed air is cooled after the purification and before the drying.
A device for processing compressed air, having a pressure line (3) which conducts compressed air and in which a device (7, 18, 27) for removing contaminants, such as hydrocarbon compounds and oil products, and a drying unit (13) are arranged in series in a throughflow direction (8), characterized in that the pressure line (3), in its portion situated upstream of the device (7, 18, 27) for removing contaminants with respect to the throughflow direction (8), is designed such that the contaminants present in gaseous form condense and the water mass contained in the compressed air is dissolved as steam.
