Active capture device for African swine fever aerosol and detection method therefor

An active capture device for African Swine fever aerosol, comprising a hollow casing, and an aerosol capture mechanism and an internal circulating filtering mechanism which are disposed inside the hollow casing, wherein

• the hollow casing comprises a top plate and a bottom plate, and an annular side plate disposed between edge positions of the top plate and the bottom plate;
• the aerosol capture mechanism comprises a ventilation duct disposed at the front end of the annular side plate;
• one end of the ventilation duct is disposed inside the hollow casing and the other end of the ventilation duct penetrates through the annular side plate and is disposed outside the hollow casing;
• a fan is disposed inside the hollow casing;
• the fan is communicated with the ventilation duct;
• an adsorption pipe network is disposed inside the ventilation duct;
• the internal circulating filtering mechanism comprises a circulating water pump disposed inside the hollow casing and on the bottom plate;
• a water inlet pipe is disposed at a water inlet end of the circulating water pump;
• a free end of the water inlet pipe penetrates through the ventilation duct to be communicated with one side of the adsorption pipe network;
• a liquid outlet pipe is disposed at a water outlet end of the circulating water pump;
• the free end of the liquid outlet pipe penetrates through the ventilation duct to be communicated with the other side of the adsorption pipe network;
• the adsorption pipe network communicates the liquid inlet pipe with the liquid outlet pipe to form a circulating pipe body;
• a 200 nm filtration membrane is disposed on the liquid inlet pipe;
• an ultrafiltration membrane is disposed on the liquid outlet pipe;
• a plurality of penetrating through holes are correspondingly formed in two sides of pipe bodies of the adsorption pipe network;
• and semipermeable membranes are disposed at the inner sides of the pipe bodies of the adsorption pipe network.
