The wide spacing ESP with conventional ESP characteristics, also has the following characteristics:
Trap dust resistance range from 10'-5X10 "Q.cm widening to 10'-10" .f / cm, that is able to capture as dry process rotary kiln, clinker grate cooler fold high resistivity dust, mitigate or eliminate back corona failure.
2, with the widening of the pole pitch, effective driving speed, with the dust collecting area is inversely proportional to higher improvement factor of 1.1 to 1.3, also exist. Therefore, improved collection efficiency, and to maintain long-term stability and efficient operation.
Hardly generated spark discharge state, the voltage can rise very high, reducing the probability of burnout corona wire due to galvanic corrosion, and thus avoids the arc discharge between the electrodes.
 4, the widened pole pitch, the distribution of the electric field strength of the electrode surface with a corona current density distribution uniformity, reducing the probability of anti-halo failure. While enhancing the dust electrostatic agglomeration effects.
 5, depending on the electric field order can design different pole spacing, which is favorable for trapping fine dust, and thus improve the collection efficiency the best pole spacing is 400 ~~ 560mm, dealing with the nature of the gas and dust in the cement industry, electrode spacing plus wide collection efficiency declines.
6, the electric field is set trough electrode, the airflow shielding effect of dust effects.
7, using the "W" prick corona electrode, with a halo low voltage, corona current density, rigidity continuous line, easy cleaning, low cost characteristics. To improve the electric field mild beneficial effect of corona current density of dust.
8, using hot air cleaning devices, to prevent a dusty gas high voltage insulator pollution fouling climb scanning electron breakdown failure, stable supply of electric field.
Pole spacing widened metal structure reduced weight, reduce equipment price. While reducing the load of the column foot of civil construction.
10, rectifier transformer high-voltage power supply unit is placed in the top of the ESP, eliminating the need for part of the cost of the high-voltage cables and control room, which also eliminates the high voltage cable fault.
