TW201724133A - Air respirator dryer including a pipe set, and an upper cover and a lower cover for covering the pipe set - Google Patents

Abstract

An air respirator dryer is communicated with an oil reservoir of a large transformer. The air respirator dryer is provided with a pipe set, and an upper cover and a lower cover for covering the pipe set. A weight sensing device is installed above the lower cover. A heating device is installed below the upper cover. When the weight sensing device detects that the weight of a desiccant arranged in the pipe set is increased due to absorption of water in the air, the weight sensing device enables the heating device to heat the desiccant, so as to remove the water absorbed by the desiccant. After evaporating, the water is condensed on an inner wall of an outer pipe and flows outward from the lower cover, so as to ensure that the desiccant can be repeatedly and normally used.
