Description

Technical Field

[0001] The utility model belongs to the field of detection equipment, and in particular relates to chemical waste gas detection equipment. Background Art

[0002] With the acceleration of the industrialization process, the chemical industry has developed particularly rapidly, but it has also brought about a large number of waste gas emissions. These waste gases contain a variety of harmful substances, such as hydrocarbons, alcohols, aldehydes and organic waste gases, as well as inorganic waste gases such as sulfur oxides, nitrogen oxides, and carbon oxides, which pose a serious threat to the environment and human health. Therefore, it is particularly important to accurately and real-time monitor chemical waste gases.

[0003] Traditional waste gas monitoring methods mainly rely on manual sampling and laboratory analysis. Monitoring personnel use handheld suction devices to capture waste gas generated during the production process, and then analyze it through a waste gas analyzer. However, when capturing waste gas from high places, chemical waste gas detection equipment in the prior art usually requires monitoring personnel to manually hold the suction mechanism, which is more laborious and inconvenient for rapid capture and monitoring of waste gas from high places, and needs further improvement.

[0004] Therefore, a chemical waste gas detection device is proposed. When capturing waste gas at high places, the device has a supporting mechanism, which does not require monitoring personnel to manually hold the exhaust mechanism, thereby facilitating the rapid capture and monitoring of waste gas at high places.
