[0002] Industrial waste gas is a general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead and mercury, beryllium, smoke and production dust, which are discharged into the atmosphere and pollute the air. Industrial waste gas detection is an important means to protect the environment and maintain people's health. It can help us understand the composition and emission of industrial waste gas, and timely discover and solve environmental pollution problems.

[0003] When current waste gas sampling devices are used to sample industrial waste gas, samplers generally first unscrew the protective cover that is threadedly connected to the sampling port, and then use the sampling tube to sample the waste gas. The moment the protective cover of the sampling port is opened, the industrial waste gas will diffuse into the surrounding air through the sampling port. The surrounding samplers will inhale these waste gases, which will have adverse effects on their health. At the same time, these industrial waste gases will also cause environmental pollution.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a contactless waste gas sampling device for industrial waste gas detection is provided, in order to achieve a more practical purpose. Utility Model Content

At the same time, the discharged industrial waste gas can be purified by the activated carbon purifier 22, which greatly improves the environmental protection of the device.
