Experimental Study on Agglomeration of Smoke Particle in Electric Field

The agglomeration phenomenon of the charged smoke particle has been investigated by the electricfluid mechanics and transport theory of external force field and depending on several simplifying assumptions the theoretical expression for the agglomeration rate of the smoke particles has been developed. In a model of electrostatic precipitator the agglomeration mechanism of charged particles has been studied further. It is shown that the agglomeration of the charged smoke particles are affected by charge distribution on the surface of particles, particle size and charge polar of particle, particle charges and so on. No matter single polar corona or bipolar corona the agglomeration of smoke particles will take place but the agglomeration occurring between particles with negative charges and particle with positive charges will be limited within a certain scope.
