Simulation and measurement of charged particle trajectory with ionic flow in a wire-to-plate type electrostatic precipitator

We have studied the behaviour of a charged particle in an axially symmetric magnetic field having a neutral point, so as to find a possibility of confining a charged particle in a thermonuclear device. In order to study the motion we have reduced a three-dimensional motion to a two-dimensional one by introducing a fictitious potential. Following Schmidt we have classified the motion, as an ‘off-axis motion’ and ‘encircling motion’ depending on the behaviour of this potential. We see that the particle performs a hybrid type of motion in the negative z-axis, i.e. at some instant it is in ‘off-axis motion’ while at another instant it is in ‘encircling motion’. We have also solved the equation of motion numerically and the graphs of the particle trajectory verify our analysis. We find that in most of the cases the particle is contained. The magnetic moment is found to be moderately adiabatic.

Plate-type electrostatic precipitators are the largest and most used industrial dusts control, most applications are in the production of electricity (thermoelectric power plants). In many industrial applications, plate-type precipitators have three sections and silicon-controlled rectifier power supplies type. Although, the collection efficiency obtained by these type of precipitators are more than 95%, most of the dust particles with diameter less than 10 μm remain un-collected. To improve the collection efficiency different electrical and/or mechanical options can be used. To improve the collection efficiency of industrial plate-type precipitators, the paper presents two practical options. The first solution would be replacing the power supplies silicon-controlled rectifier - with other special power supplies (intermittent power supplies, high frequency power supplies) depending on the dust resistivity; the second solution would be to add a new section at precipitator an expensive solution, usually the last. The technological and electrical sizes, simulated and measured, are presented for the proposed solutions.
