Description
Technical Field
[0001] The utility model relates to the technical field of flue gas analysis instruments, in particular to a smoke sampling tube docking structure. Background Art
[0002] The smoke and flue gas tester uses the Pitot tube isokinetic sampling weight method to capture particulate matter in the pipeline, and uses the constant potential electrolysis method to qualitatively and quantitatively determine harmful gases. The main functions of the smoke and flue gas tester are smoke sampling and flue gas analysis.
[0003] Taking the existing YLB-3330D large-flow, low-concentration smoke and flue gas tester as an example, when sampling oil smoke, it is equipped with a YLB-L08 oil smoke sampling tube (or sampling gun), and the head of the sampling tube needs to be installed with an oil smoke filter cartridge; when sampling smoke, it is equipped with a YLB-L01 multi-function sampling tube, and the head of the sampling tube needs to be installed with a sampling hook and a No. 3 filter cartridge; when sampling low-concentration smoke, it is equipped with a YLB-L04 sampling tube, and the head of the sampling tube needs to be installed with a low-concentration sampling head and heating; and when analyzing smoke, it is mainly equipped with a YLB-L11 smoke preprocessor or a YLB-L14 smoke sampling tube; therefore, different sampling tubes need to be replaced for use in different scenarios, and the function of a single sampling tube is relatively single, and a large number of them is inconvenient to carry.
