Embodiment 1
[0039] The efficient collection method of nanoparticle of embodiment 1
[0040] First, the airflow containing nano-particles with a particle size ranging from 20nm to 10000nm enters the primary dust collection and charging area. The primary dust collection and charging area is equipped with an electrostatic precipitator that can charge the particles positively and negatively. After removing larger particles , the airflow containing particles is divided into two parts, so that some particles are positively charged, and some particles are negatively charged; the two-phase airflow mixes and enters the induced agglomeration zone. Due to the different charges of the particles, the particles attract each other and agglomerate into larger particles. In the area of induced agglomeration, the probability of agglomeration of particles can be increased by changing the velocity and direction of the mixed airflow. After mixing, the airflow enters the secondary dust collection area and is...
Embodiment 2
[0042] Such as figure 1 As shown, a high-efficiency collection device for nano and micro particles includes a primary dust collection and charging unit 1 , an induced agglomeration unit 2 and a secondary dust collection unit 3 connected in sequence. The primary dust collection and charging unit 1 includes a positively charged plate type electrostatic precipitator and a load electric plate type electrostatic precipitator, and the induced agglomeration unit 2 is an airflow mixing channel whose inner diameter is smaller than that of the primary dust collection and charging unit . The secondary dust collection unit 3 is a plate electrostatic precipitator.
