Abstract
The three-electrode electrostatic precipitator (ESP) is a potentially effective purification technology for removing suspended particulate matter. In order to enhance the efficiency in the three-electrode ESP, a magnetic field was introduced, a theoretical coupling model was created for multiple physical fields, and the electromagnetic confinement effect in the ESP at various flue gas velocities and working voltages was simulated and analyzed using CFD software. Based on this, the electromagnetic confinement removal mechanism of PM2.5 is studied. The findings of the research demonstrate that the electromagnetic confinement effect can enhance the three-electrode ESP's capacity to remove dust, particularly when it comes to small-sized particle removal. When the voltage and velocity decrease, the electromagnetic confinement effect increases. The effectiveness of ESP dust removal steadily declines with rising voltage and velocity as the magnetic induction intensity rises. The findings of the research offer experimental evidence and theoretical backing for enhancing the three-electrode ESP's performance.
期刊介绍：
Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests:
Formation and synthesis of particles by precipitation and other methods.
Modification of particles by agglomeration, coating, comminution and attrition.
Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces).
Packing, failure, flow and permeability of assemblies of particles.
Particle-particle interactions and suspension rheology.
Handling and processing operations such as slurry flow, fluidization, pneumatic conveying.
Interactions between particles and their environment, including delivery of particulate products to the body.
Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters.
For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
