The present invention discloses an aerosol concentration and enrichment system, which comprises: an impact cutter provided for receiving a gas flow, wherein at least partial particulate matters having an aerodynamic equivalent diameter more than a first preset valve are removed; a water bath device provided for receiving the gas flow from the impact cutter so as to make the gas flow from the impact cutter and the water vapor produced by the water bath device be mixed; at least a freezing device, wherein each freezing device is used for receiving the mixed gas flow from the water bath device so as to increase the aerodynamic equivalent diameter of at least partial particulate matters in the mixed gas to more than or equal to a second preset value; and at least a concentration and separation device, wherein each concentration and separation device is used for receiving the gas flow from the freezing device, performing the diversion on the gas flow from the freezing device to obtain a first gas flow and a second gas flow, and making the particulate matters having the aerodynamic equivalent diameter more than or equal to the second preset value in the gas flow from the freezing device be completely or partially positioned at the first gas flow.
Description
technical field [0001] The invention belongs to the technical field of increasing the concentration of small particles in airflow, and in particular relates to an aerosol concentration enrichment system. Background technique [0002] With the development of social economy and the improvement of people's living standards, factories and automobiles emit more and more exhaust gas, which easily makes the atmosphere turbid, blurs the vision and leads to deterioration of visibility, resulting in haze weather. Haze is mainly caused by sulfur dioxide , Nitrogen oxides and respirable particulate matter, which are combined with mist to make Sky It became gloomy and gray in an instant. sulfur dioxide , Nitrogen oxides As gaseous pollutants, inhalable particulate matter is the chief culprit that aggravates the pollution of haze weather. The abbreviation for particulate matter is PM , Beijing monitors the PM2.5 , that is, the aerodynamic equivalent diameter is ...
