Description

Technical Field

[0001] The utility model relates to the technical field of smoke sampling, in particular to a cyclone type smoke sampling probe. Background Art

[0002] Smoke and dust are solid particles suspended in the gas formed by the heat process of oxidation, sublimation, evaporation and condensation. For example, the flue gas of the converter contains a large amount of extremely fine smoke and dust. In areas with severe desertification, a strong wind will blow up a large smoke and dust storm. Smoke and dust are solid particles emitted during coal burning and industrial production. Its main components are silicon dioxide, aluminum oxide, iron oxide, calcium oxide and unburned carbon particles. There are many types of air pollutants, which can be summarized into two categories according to their form, namely particulate pollutants and harmful gases. Smoke and dust belong to particulate pollutants.

[0003] A new type of smoke sampling device is disclosed in the patent with publication number: CN218847748U. In this solution, sampling is mainly carried out by pumping air through a piston structure. This method of taking and placing is inefficient, and the amount of samples obtained is small, which is inconvenient to use. Utility Model Content
