Causes of reduced dust removal efficiency of electrostatic precipitators

The use of electrostatic precipitators in life can sterilize and prevent infectious diseases, and can protect the health of family members. The power supply of electrostatic precipitators consists of control box, step-up transformer and rectifier. The voltage output of the power supply has a great effect on dust removal efficiency. influences.

The working principle of the electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas, and the dust charge in the gas stream is separated from the gas flow by the electric field.

The performance of electrostatic precipitators is affected by three factors: dust properties, equipment construction and flue gas flow rate.

What factors will reduce the efficiency of electrostatic precipitator dust removal? The specific resistance of the dust is a factor that affects the dust removal efficiency of the electrostatic precipitator. The specific resistance is low, and the dust particles are difficult to maintain on the dust collecting electrode, causing it to return to the airflow; if the specific resistance is too high, the dust particles reaching the dust collecting electrode are not easily discharged, and a voltage gradient is formed between the dust layers to cause partial breakdown and Discharge phenomenon, these conditions will lead to a decrease in the efficiency of electrostatic precipitator dust removal.

What are the advantages of the electrostatic precipitator? 1. High purification efficiency 2. Low resistance loss 3. Allowable high operating temperature 4. Large processing gas range 5. Automatic operation control can be fully realized.

After talking about the advantages of electrostatic precipitators, each of them has advantages and has its shortcomings. Let's talk about the shortcomings of electrostatic precipitators!

1. The equipment is more complicated, requiring high level of equipment transportation and installation and maintenance management.

2, there are certain requirements on the dust specific resistance, so there is a certain selectivity to the dust, can not make all the dust to obtain a high purification efficiency.

3, affected by the operating conditions of gas temperature, temperature, etc., the same kind of dust, such as operating under different temperatures and humidity, the effect is different, some dust is used well under a certain temperature and humidity, and In another temperature and humidity, it is almost impossible to use an electrostatic precipitator due to changes in dust resistance.

4. One investment is large, and the horizontal electrostatic precipitator has a large area.

5, in some enterprises, the practical effect can not meet the design requirements.
