Abstract
An air drying and purification system for compressed air is disclosed. The system is adapted particularly for use with dental compressors. The system comprises: (a) a centrifugal separator chamber for at least partially drying and purifying cooled compressed air from a compressor by separating moisture and other contaminants from the compressed air, (b) a drying chamber containing a bed of absorbent material for absorbing moisture from the cooled, partially dried and purified compressed air, and (c) an assembly for periodically ventilating the separator and drying chambers. A particular feature of the system is that the compressed air that is vented periodically from the drying chamber is used to cool compressed air at elevated temperatures from the compressor.
Claims17
An air drying and purification system for compressed air from a compressor, comprising:
- (a) a centrifugal separator chamber for at least partially drying and purifying cooled compressed air from the compressor by separating moisture and entrained particulate material and other contaminants from the compressed air, the separator chamber having an inlet for compressed air and an outlet for discharging at least partially dried and purified compressed air;
- (b) a drying chamber for further drying the compressed air, the drying chamber containing an absorbent material for absorbing moisture from the compressed air, the drying chamber having an inlet for introducing compressed air from the separator chamber and an outlet for discharging dried and purified compressed air;
- (c) a one-way valve between the separator chamber and the drying chamber for preventing flow of compressed air from the drying chamber to the separator chamber;
- and
- (d) an assembly for ventilating the chambers to regenerate the absorbent material in the drying chamber and to remove contaminants from the separator chamber, the assembly comprising:
- (i) a vent outlet in the separator chamber;
- (ii) a vent outlet in the drying chamber;
- and
- (iii) a valve assembly for opening and closing the vent outlets.
