Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a sampling device for air pollution prevention and control. Background Technology

[0002] Air pollution prevention and control refers to activities aimed at reducing air pollutant emissions, improving air quality, and protecting the environment and human health through various measures and means. Air pollutants mainly include harmful gases and particulate matter. Harmful gases include sulfur dioxide, nitrogen oxides, and carbon monoxide, while particulate matter includes inhalable particulate matter and fine particulate matter. These pollutants can cause serious harm to human health and the ecological environment, such as causing respiratory diseases, heart disease, and lung cancer, and can also affect agricultural production and the balance of ecosystems.

[0003] Sampling equipment is required for air pollution control. Existing sampling equipment typically uses a sampling pump to draw air samples, but the pump operates at a fixed height, making it impossible to sample and detect pollutants at different altitudes, which affects the effectiveness of air pollution control. Furthermore, the sampling tubes usually store the sampled gases in a unified manner, making it impossible to classify and store gases at different altitudes, which also affects the efficiency of air pollution control.

[0004] Therefore, it is necessary to provide a new sampling device for air pollution control to solve the above-mentioned technical problems. Utility Model Content
