Dust Collecting System Introduction


The power of electrostatic precipitator is composed of control cabinet, step-up transformer and rectifier. The power supply voltage has great influence on collection efficiency, therefore, the operation voltage must keep 40-75kv and more above 100kv.


The working principle of electrostatic dust collector is to use high voltage electric field making flue gas ionization, the dust charged and separated from flue gas by means of electric field. Cathode is made from different cross section shape of metal wires called discharge electrode, anode is made from different geometrical shapes of metal plate called dust collecting electrode. 


There are three factors to affect the performance of electrostatic dust collector: 

dust properties, structure of equipment and gas velocity. 


The specific resistance of dust is the evaluation index of electrical conductivity and has direct influence to dust collection efficiency.

Electrostatic Dust Collector


This is the new product with advanced technology and be put into service successfully in Local China. It is the ideal equipment for industrial waste gas treatment to capture the dust in the air through electrostatic purification method, which mainly depends on discharge electrode and receiving electrode to complete the whole process. Both of these electrode systems have vibrating device to de-dusting.


Dust Separator Nature


Advantage

low pressure loss, 

generally 200-500pa large gas volume, 

1000000-10000000 m³/h low energy consumption, 

about 0.2-0.4 kwh/1000 m³ high efficient collection for fine particles, 

>99% can be operation under high temperature and strong corrosive gas 


Weakness 

1.high investment 

2.high requirement for installation 

3.special request for dust rate resisitance


ESP Dust Filter Working Principle


Three basic process: 

Suspension of charged particles---high voltage DC corona 

Movement and collection of these charged particles in electric field---continuous corona field or pure electrostatic field. 

Deashing process---the dust is dropped into ash bucket by vibrating.
