Online particle depolymerization system based on aerosol agglomeration principle

Abstract

An online particle depolymerization system based on an aerosol agglomeration principle comprises a two-stage vibration dispersion module, an electrostatic neutralization module and a measurement and control system, wherein the two-stage vibration dispersion module and the electrostatic neutralization module are connected in sequence, the measurement and control system is connected with the two-stage vibration dispersion module and the electrostatic neutralization module, and agglomerated particles from an air inlet pipeline are dispersed into aerosol with the particle size ranging from 1 micrometer to 200 micrometers after being subjected to two-stage vibration dispersion and electrostatic neutralization. According to the principle of destroying the surface force between particles, the van der Waals force between the particles is broken by vibrating the dispersion chamber and adopting the two-stage dispersers which vibrate at high frequency and are connected in series, and then the particles reach a charge balance state and electrostatic force is eliminated through the electrostatic neutralization chamber, so the function of online particle depolymerization is realized.

Description

technical field [0001] The invention relates to a technology in the field of aerosol treatment, in particular to an online particle deaggregation system based on the principle of aerosol agglomeration. Background technique [0002] Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gaseous medium. When particles move in the flow field, due to the surface force between the particles, that is, van der Waals force and electrostatic force, etc., the particles will agglomerate and generate secondary particles with larger particle sizes. The change of particle size will change the movement state of the aerosol , further affecting the agglomeration process of particles. The agglomeration and the agglomeration structure formed by the agglomeration not only change the interaction relationship between the gas-solid two phases, but also affect the heat and mass transfer process between the gas-solid two phases and between particles.
