The invention provides an unmanned aerial vehicle double-hemisphere sampling device and an atmospheric pollution source emission quantification method. The device comprises an online monitoring device, a double-spiral-arm sampling device and an onboard computer data transmission control system. The device can simultaneously monitor and sample double points, and is particularly suitable for double-spherical sampling. And in cooperation with an unmanned aerial vehicle monitoring path planning system, atmospheric pollutant concentration data of a smoke plume specified point array around the exhaust funnel can be quickly obtained. According to the method, the atmospheric pollutant emission flux of each grid is calculated and summed on the basis of the double-spherical atmospheric pollutant monitoring result of the unmanned aerial vehicle, and the overall atmospheric pollutant emission amount of the exhaust funnel is calculated in combination with the flight time, so that the method has relatively good flow field closing performance and stability, and is suitable for large-scale popularization and application. The influence of a small micro-scale complex three-dimensional meteorological field of ambient air and the uncertainty influence of an air quality simulation method are reduced. According to the device and the method, the effectiveness, the accuracy and the stability of smoke plume emission quantification of the exhaust funnel can be effectively improved.
