Description

Technical Field

[0001] The utility model relates to the field of waste gas sampling, and more specifically, to an industrial waste gas sampling device. Background Art

[0002] In industrial production, the production of products or the combustion of fossil fuels will generate a large amount of waste gas. The waste gas needs to be purified before it can be discharged into the atmosphere, otherwise it will pollute the environment. Before the waste gas is discharged, it is necessary to sample and test the waste gas discharged in the production to determine whether the waste gas meets the emission standards. Therefore, it is necessary to use a waste gas sampling device to sample the waste gas. The existing sampling device is generally only a container that can store gas. When sampling the waste gas, the waste gas is drawn into the container and stored by the container. The container is prone to damage. The existing sampling device lacks a protective structure. When the container is damaged, the collected waste gas will be released. If the waste gas contains more dangerous and harmful substances, it is easy to cause harm to the sampling personnel and pollute the environment. The existing sampling device lacks a cleaning structure. After the gas detection is completed, the waste gas often contains impurities such as micro particles and dust, which are adsorbed on the inner wall of the sampling container. The existing sampling device lacks a cleaning structure and cannot immediately clean the sampling container, thereby affecting the repeated use of the sampling device. Utility Model Content
