Device suitable for automatically purging sampling tube of demister differential pressure transmitter of desulfurizing absorption tower

The utility model relates to a device suitable for automatically purging a sampling pipe of a differential pressure transmitter of a demister of a desulfurizing absorption tower, which comprises the sampling pipe communicated with the demister of the absorption tower, and the upper end of the sampling pipe is connected with a sampling instrument pipe through a Farad disc structure. A sampling isolation door is arranged on the sampling instrument pipe, the other end of the sampling instrument pipe is connected with a transmitter, a flushing pipe with the other end connected with a flushing water source is connected beside the sampling instrument pipe, and an electromagnetic valve with a timing function is mounted on the flushing pipe. The device can stably operate for a long time, timely and accurately measure the differential pressure of the demister of the absorption tower, ensure safe and stable operation of a desulfurization system, reduce human intervention and avoid risks in a re-dredging process. 本实用新型涉
