ABSTRACT:
A compressed air strainer and drying treatment is provided in which a filter core of the strainer can be used successively without replacement. The strainer includes a strainer main trunk, an admitting pipe stretching into the inside of the main trunk, a water intake apparatus on one side of the top end of the main trunk, and an escape pipe set on the other side of the top end connecting a heat exchanger. An automatic drainer and a manual drainer are coupled to one side of the main trunk. On another side of the main trunk, a check valve is provided and a U-shaped pipeline connects the strainer to the evaporator. The drying treatment is accomplished by splitting the inlet compressed air into many fine streams by filter baffle plates to generate innumerable small bubbles and thereby increase the contacting area between the air and the water. Oil, dirt and contaminants are carried into the air bubble and then are filtered therefrom. The air is then passed through a heat-exchanger to lower the temperature of the air. Condensed water is led back into the strainer via the U-shaped pipeline and a check valve. When the water in the strainer gets to a certain level, the automatic drainer will operate, or by opening the manual drainer, the oil, dirt and contaminants can be drained from the strainer.
