APPARATUS FOR TREATING DRAIN OF COMPRESSOR

摘要

PURPOSE:To remove a turbidity component by a natural flowdown system without arranging a rotary driving part at all, by integrating a treatment tank for adsorbing floatable oil or dispersed oil by filtering with a treatment tank for adsorbing emulsified oil by filtering. CONSTITUTION:A first treatment tank 4 is packed with a fibrous substance having good water permeability and having filtering, adsorbing and collecting capacities of floatable oil, dispersed oil or floatable substance rich in olephilicity and having a relatively large particle size while a second treatment tank 7 is packed with a fibrous substance having good water permeability and function for filtering and adsorbing extremely fine oil droplets emulsified with a drain. Only drain water is naturally flowed down to the first treatment tank 4 from a gas-liquid separation filter tank 2. The treated water is naturally flowed down to the second treatment tank 7 to be subjected to final treatment. Further, for the purpose of sound arresting and the prevention of oil droplets from scattering, it is pref. to mount filters to an exhaust tank 3.
