Mechanism and experimental study on the effect of electric field on organic amine aerosol
utilization and storage(CCUS) in coal-fired power plants is an important approach to achieve the goal of 2060 carbon neutrality. However
the chemical absorption method has problems such as the secondary carrying of absorbents and the generation of new aerosol pollutants. To explore the action mechanism of the electric field on organic amine aerosol
the authors employ the COMSOL software to simulate the difference between the charge characteristics and movement characteristics of organic amine aerosols and solid particles in the space electric field. In addition
they use experimental methods to study the effect of organic amine aerosol on volt-ampere characteristics of the wire-plate electrostatic defogger. Finally
this article analyzes the control effect of electric field on organic amine aerosol by ELPI+. The results show that
the current between the plates increases with the voltage
which is approximately an exponential function. When the distance between the poles is constant
the current decreases with the increase of the distance between the plates. When the distance between the plates is constant
the current increases with the distance between the plates
and the maximum corresponding size is 7 cm between the board and 7 cm between the lines. The removal efficiency of the electric mist eliminator for 0.2~0.5 μm particles is 40%. Organic amine aerosol has higher relative permittivity and higher surface tension
and their removal rate in the mist eliminator is higher than that of solid particles. The difference in particle size below 0.1 μm is about 2 percentage points
and the difference in particle size above 0.1 μm is about 8 percentage points.
