Abstract
The invention is a contaminant removal system for purifying air. Incoming air is cooled to a cryogenic temperature. A vortex tube further cools the cooled air so as to solidify contaminants therein. A filter system then filters out the solidified contaminants from the air. Use of a vortex tube minimizes the amount of moving parts. This reduces maintenance and concommitant costs involved with operation. The present system has a long life. The vortex tube is relatively inexpensive.
Claims9
A contaminant removal system for purifying air comprising:
- a) a compressor for pressurizing incoming air to a cryogenic temperature;
- b) a radiator for cooling the pressurized air supplied by said compressor;
- c) a primary heat exchanger for further cooling the pressurized air supplied by said radiator;
- d) a vortex tube for further cooling the cooled air supplied by said primary heat exchanger so as to solidify contaminants therein;
- and,
- e) a filter system for filtering out said solidified contaminants from said air.
