[0002] The importance of environmental protection is self-evident at present, especially the pollution caused by industry and enterprises, which has led the country to strictly control it. The denitrification system of thermal power plants continuously cycles from sampling to measurement to adjustment to ensure that the smoke exhaust data meets the standards. No matter which link has problems, it will affect the efficiency of the entire denitrification system.

[0003] During the flue gas collection process, the metal sampling rod is corroded by acid gas, which increases the air resistance in the flue gas flow and even causes blockage, seriously affecting the continuity and stability of flue gas collection, and further distorting the data entering the analytical instrument.

[0004] The patent document with publication number CN203385594U proposes a flue gas sampler liner tube sampling rod. The device includes a soldering rod, a fixing screw sleeve, a locking nut joint and a φ8 polytetrafluoroethylene tube. One end of the φ8 polytetrafluoroethylene tube is inserted into the locking nut joint and clamped. The locking nut joint is screwed into the fixing screw sleeve, and the fixing screw sleeve is fixed inside the soldering rod. The utility model changes the current situation of using only metal rods as sampling rods. It has a simple structure, low air resistance, easy processing and installation, low cost, and can reduce the continuity and stability of sampling in high-temperature flues, high humidity, and high-corrosion conditions. The liner tube sampling rod is ingeniously designed and highly practical, effectively reducing product maintenance costs and correspondingly improving the effective operation of the product.
