Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a processing device for an instrument gas pipeline gas source. Background Technology

[0002] The micro-heating air dryer in the air compressor station of Shagang Power Plant uses its own air supply for the solenoid valve instrument air source. This instrument air source may contain impurities such as alumina powder, moisture, and solid particles, which will directly enter the instrument air pipeline and easily clog the solenoid valve orifice when supplied to the solenoid valve. This can cause the solenoid valve to malfunction, resulting in slow or sluggish operation of the dryer switching valve, frequent failures, and affect the normal operation of the equipment. Frequent replacements are required, which greatly increases the operating cost. Therefore, we propose a treatment device for the instrument air pipeline air source to solve the above problems.
