Description

Technical Field

[0001] The utility model relates to the technical field of smoke and fume sampling devices, in particular to a smoke and fume sampling device with a replaceable pitot tube. Background Art

[0002] The main sources of air pollution are the random emission of factory exhaust and the burning of large amounts of fuel. Harmful gases include carbon monoxide, nitrogen dioxide, sulfur dioxide, etc., and greenhouse gases include carbon dioxide, methane, nitrous oxide, etc. It is urgent to study the emission of gases at the source to control the emission of harmful gases. However, in actual industrial production, the exhaust gas is generally high temperature and accompanied by a large amount of dust. If accurate gas analysis is to be performed, the smoke must be purified and dusted, which places high demands on the smoke sampling system.

[0003] According to the national standard GB / T16157-1996. The smoke and flue gas tester needs to use a sampling tube to extract the smoke, flue gas, flow rate, smoke temperature and other data in the sample flue to participate in the calculation of the tester. The pitot tube units of the existing smoke and flue gas sampling tubes are welded to the sampling tube body and cannot be disassembled and replaced. During use, the pitot tube may be accidentally damaged or bent, resulting in inaccurate pitot tube test data, which in turn causes deviations in the smoke and flue gas tester data. Only by purchasing a new sampling tube or cutting the pitot tube and re-welding it for repair, the cost of use is high and the maintenance process is cumbersome.

[0004] Therefore, it is necessary to provide a replaceable structure of the Pitot tube in the smoke and flue gas sampling tube to solve the above technical problems. Utility Model Content
