The invention relates to the technical field of experimental equipment, and discloses a ventilation device for a pollutant gas exposure cabin, the ventilation device comprises a gas inlet pipeline, a ventilation treatment box and a gas outlet pipeline which are connected in sequence, and a cooling unit, a heating unit and a humidity adjusting unit for adjusting gas are arranged in the ventilation treatment box; the cooling unit is arranged at the end, connected with the air inlet pipeline, of the air exchange treatment box, the air outlet pipeline comprises a main pipeline and at least two branch pipelines connected with the main pipeline, the main pipeline is connected with the air exchange treatment box, and the branch pipelines are used for being connected with the clean air contrast cabin and the pollutant gas exposure cabins. When entering the ventilation treatment box through the air inlet pipeline, air firstly passes through the cooling unit, the cooling unit firstly cools, condenses and dehumidifies the air, the air passes through the humidity adjusting unit and the heating unit after the temperature of the air is reduced, and the air enters the exposure cabin through branch pipelines of the air outlet pipeline after the air reaches proper temperature and humidity. The temperature and humidity of the air meet experimental requirements, and the accuracy of experimental results is ensured.
Description
technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a ventilation and ventilation device for a pollutant gas exposure chamber. Background technique [0002] With the acceleration of modern industrialization and urbanization in my country, the problem of air pollution is becoming more and more serious, and the exhaust emission of motor vehicles is one of the main sources of pollutants. By the end of 2021, the Traffic Management Bureau of the Ministry of Public Security announced that the national motor vehicle ownership reached 395 million. With the rapid increase in the number of motor vehicles, the problem of traffic-related air pollution (TRAP) has become increasingly prominent. , the main pollutant types of TRAP include particulate matter (PM), volatile organic compounds (VOCs: alkanes), polycyclic aromatic hydrocarbons (PAHs), carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), Hydrocarbons (HC),...
