Air dust removal system and method

A method for reducing coupling of an the dedusting electric field, including the following steps:

• selecting a parameter of the dedusting electric field anode and/or a parameter of the dedusting electric field cathode so as to reduce the coupling time of the electric field,
• further including selecting the dedusting electric field anode to have a length of any one of the following:
• 10-180 mm, 10-20 mm, 20-30 mm, 60-180 mm, 30-40 mm, 40-50 mm, 50-60 mm, 60-70 mm, 70-80 mm, 80-90 mm, 90-100 mm, 100-110 mm, 110-120 mm, 120-130 mm, 130-140 mm, 140-150 mm, 150-160 mm, 160-170 mm, 170-180 mm, 60 mm, 180 mm, 10 mm, 30 mm, 10-90 mm, 15-20 mm, 20-25 mm, 25-30 mm, 30-35 mm, 35-40 mm, 40-45 mm, 45-50 mm, 50-55 mm, 55-60 mm, 60-65 mm, 65-70 mm, 70-75 mm, 75-80 mm, 80-85 mm and 85-90 mm.
