High-pressure electrostatic dust collector
High-voltage electrostatic precipitator is a device that uses electrostatic purification to collect dust in flue gas. It is an ideal equipment for purifying industrial waste gas. The purification work is mainly completed by the anode and the precipitate pole systems. When a high-voltage direct current is input between the two poles, dust particles in the flue gas surface produce positive and negative ions under the action of the electrostatic field, and move towards the electrodes with the opposite polarity under the action of the electric field force, depositing on the electrodes to achieve the purpose of dust removal. Both systems have vibration devices. When the vibration hammer strikes the two-pole device regularly, the attached dust is shaken off and falls into the lower ash hopper through the ash discharge device. The purified waste gas is discharged into the atmosphere through the outlet and the chimney, and the process of flue gas purification is completed.

The Working Principle of High-Voltage Electrostatic Precipitator
The working principle of a high-voltage electrostatic precipitator mainly relies on the ionization of flue gas by a high-voltage electric field. Dust in the air stream acquires negative charges under the influence of the electric field and is then drawn towards the anode plates or the dust-removal electrodes. Specifically, an electrostatic precipitator is primarily composed of two parts: the electrode for emission and the electrode for dust collection. The electrode for emission is typically made up of metal wires with different cross-section shapes, while the electrode for dust collection is composed of metal plates with various geometric shapes. When a high-voltage direct current (HVDC) power supply is applied between the two poles, a large number of positive and negative ions are generated in the space between the electrodes, which are then adsorbed by the dust particles in the air flow. Under the influence of the electric force, the dust particles with negative charges move towards the anode, and upon reaching the anode, they release electrons, depositing on the anode plates to form purified gas. Additionally, the performance of an electrostatic precipitator is also affected by factors such as the properties of the dust, the structure of the equipment, and the velocity of the flue gas flow. If the dust has a resistance below a certain value, the dust particles may be difficult to retain on the electrode for dust collection; conversely, if the specific resistance is too high, the dust particles reaching the electrode for dust collection may have difficulty in releasing their charges, which could potentially reduce the efficiency of dust removal.
