About Improving Collection Efficiency for Industrial Plate-Type Electrostatic Precipitator
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.
