Factors affecting the function of industrial electrostatic precipitator and its purchasing parameters
The function of industrial electrostatic precipitator is affected by three factors: dust property, equipment structure and flue gas velocity. The specific resistance of dust is the target of evaluating conductivity, which has direct influence on dust removal power. The power supply of industrial electrostatic precipitator is composed of control box, boost transformer and rectifier. The output voltage of power supply also has a great influence on the dust removal power. Therefore, the operation voltage of industrial electrostatic precipitator must be 40-75kV or 100kV.
The working principle of industrial electrostatic precipitator is to use high voltage electric field to ionize the flue gas, and the charged dust in the airflow separates from the airflow under the action of electric field; its negative pole is made of metal wires with different cross-section shapes, called discharge electrodes; and its positive pole is made of metal plates with different geometrical shapes, called collecting electrodes.
Compared with other dedusting equipments, industrial ESP consumes less energy and has higher dedusting power. It is suitable for removing 0.01-50 micron dust from flue gas, and can be used in high temperature and pressure situations. Practice shows that the larger the amount of flue gas treated, the more economical the investment and operation cost of using industrial ESP.
When selecting industrial electrostatic precipitator, we need to pay attention to the performance parameters such as dust removal efficiency, manipulation elasticity, hydrophobicity, cohesiveness, water consumption, and so on. At the same time, we should not forget how the industrial electrostatic precipitator treats the mud, as well as the protection measures of the equipment itself.https://www.icleairs.com/
