AI Technical Summary
In natural gas purification stations, the manual purging of flue gas sampling pipes is labor-intensive, resulting in frequent and cumbersome sampling operations.
Design a flue gas sampling device. By setting a first electric valve on the flue gas sampling pipe and a second electric valve on the purging branch, and using a timing device to control the opening and closing of the electric valves, the automatic timed backflushing and intermittent sampling of the flue gas sampling pipe can be realized, reducing manual operation.
It has enabled automated sampling and cleaning of flue gas analyzers, reduced manual operation, improved work efficiency, and ensured the accuracy of analysis results.
