Abstract
The utility model provides a flue gas analyzer with sampling and reverse blowing, which relates to the technical field of flue gas analyzers, and comprises a flue gas analyzer and a reverse blowing structure, an inner detection cylinder is arranged in a sampling outer cylinder, the reverse blowing structure is sleeved at the upper port of the inner detection cylinder, an outer air exhaust structure is sleeved at the upper part of the reverse blowing structure, and the outer air exhaust structure is sleeved at the lower part of the reverse blowing structure. The outer air exhaust structure and the reverse blowing structure are detachably connected, a detection probe is mounted in the inner detection cylinder, a mounting plate is arranged at the lower end of the inner detection cylinder, a connecting wire is arranged at the lower end of the detection probe, and the connecting wire is electrically connected with a central processing unit in the flue gas analyzer. According to the utility model, a flue gas sample can be conveniently and quickly collected to enter the inner detection cylinder for accurate analysis, and back-blowing treatment can be carried out after analysis is completed, so that smoke dust adhered in the sampling process can be blown away and scraped, and the back-blowing structure and the outer air exhaust structure can be independently dismounted for cleaning or overhauling and maintaining, and the device is safer and more durable.
