Industrial Electrostatic Precipitator Dust Collector For Coal Fired Power Plant
Dust Collector Introduction:
GD horizontal electrostatic dust collector uses special three-electrode structure and has more extensive adaptability of dust collecting. It adds appropriate pre-charged electrode at the inlet and can achieve high collecting efficiency by low electric field. Its electric field is solid and reliable. It is economical and convenient for installation, adjustment and maintenance. It can be widely used for gas filtration in electricity, metallurgy, chemicals, building materials, paper and other industries.
Application of Electrostatic Dust Collector:
Electricity, metallurgy, chemicals, building materials, paper and other industries.
Electrostatic Dust Collector Structure:
GD horizontal electrostatic dust collector is mainly composed of housing, inlet, outlet, anode system, cathode systems, high voltage silicon rectifier transformer system, rapping device, hopper and ash discharging system, electrical control systems and other auxiliary facilities.
Features:
1. No maintenance inside electric field. Maintenance outside external electrical field can be done during running ;
2. Compact structure, small footprint;
3. Solid structure, nice rapping force transmission, a wide range of applications;
4. Large corona wire stiffness, good discharge performance, can continue to work effectively;
5. Rapping intensity, period, sequence can be adjusted in accordance with the appropriate requirements;
6. High temperature resistance, can work under 450 ℃.
