Device for liquid separation and filtration of compressed gases

Abstract

A device for liquid separation and filtration for drying and cleaning of compressed gases, which is intended, especially, for compressed air and breathing air, and in which the design is such that a centrifugal liquid separation means is located axially upstream of a filter means with a filter cartridge in the tank of the device. In the interior of the tank there is a centrifugal liquid separation means with an assigned separation space and a condensate liquid collection space axially underneath the filter means of the filter cartridge. The bottom of the filter cartridge can form the boundary wall of the separation space of the centrifugal liquid separation means. Between the outside wall of the filter cartridge of the filter means and the inside wall of the tank there is a narrow gap in which the compressed gas, after leaving the centrifugal liquid separation means, rises high along the filter cartridge as far as the opposite entry into the filter means. In this area, further post-separation or fine separation can take place. The axially successively connected arrangement of the centrifugal liquid separation means and the filter means allows a reduction in the diameter of the device and the overall arrangement leads to better operating reliability and to an improved degree of liquid separation.
