Embodiment Construction
[0027] Such as figure 1 As shown, the embodiment of the high-efficiency charging device for atmospheric fine particles of the present invention includes: an impact particle cutter 1 , a particle charging chamber 2 , and a high-voltage power supply 3 . The impact particle cutter 1 has a cylindrical structure on the outside and a cylindrical hollow structure on the inside and outside, and is composed of a sample gas inlet pipe 4 , a cutter cover 5 , a cutter wall 6 , and an inertia impact table 7 . The outer end of the sample gas inlet pipe 4 is cylindrical and used to connect to an external sampling pipe; the other end is designed as a small-hole acceleration nozzle to realize instantaneous acceleration of particles in the sample gas. The cutter cover 5 and the sample gas inlet pipe 4 are designed in one piece, with a retaining edge at the end, and connected to the cutter wall 6 through threads, and an O-ring sealing ring at the connection. The upper part of the inertia impact...
