Description

Technical Field

[0002] Exhaust gas is the gas discharged during the combustion of mineral fuels, industrial production, combustion of garbage and industrial waste, and automobile driving. The composition of exhaust gas is very complex. Some of it is toxic and harmful gas that endangers people's health. It must be treated and can only be discharged after meeting the national emission standards. In order to detect whether the exhaust gas to be discharged meets the standards, it is necessary to collect and test it; the existing exhaust gas detection and collection devices have certain disadvantages when used. After a round of exhaust gas collection is completed, impurities are still attached to the inside of the collection box, which affects the gas detection results of the next collection. In order to improve the accuracy of the detection, it is usually necessary to collect in multiple places to compare the results. Multiple collection operations are cumbersome and time-consuming. For this reason, we propose an adjustable exhaust gas detection and collection device. Utility Model Content
