Working Principle
1. Operating Principle of Electric Tar Precipitator
It captures airborne particulate matters onto collectors by means of electric field force so as to purify flue gas. Inside the device, high-voltage electric field attracts charged fine particles to electrode plates, effectively removing dust, fume, oil mist and other harmful substances from waste gas. It also prevents harmful particulates from harming human body and ensures clean and healthy air environment.
By utilizing electric field effect, the equipment collects solid particles and liquid droplets in waste gas to realize gas purification. Its core working mechanism is to charge solid particles and liquid droplets in exhaust gas, then achieve adsorption and filtration via electric field force.
2. Structural Design of Electric Tar Precipitator
The equipment consists of electrodes, collecting plates, spraying system as well as waste gas inlet and outlet. Among them, electrodes and collecting plates are core components. The spraying system sprays cleaning liquid for internal washing, while gas inlet and outlet are used for connecting flue gas pipelines.
3. Operation Mechanism
The operation is divided into two main phases: electric field working phase and cleaning phase.During electric field operation, waste gas passes through the electric field between electrodes and collecting plates, and particulates and liquid droplets are trapped on collecting plates.In the cleaning process, the spraying system sprays cleaning fluid to wash away attached pollutants, completing exhaust gas purification.
4. Maintenance Requirements
Regularly clean collecting plates to keep surface clean.
Periodically inspect connection status between electrodes and collecting plates for stable operation.
Replace cleaning liquid regularly to avoid secondary pollution to waste gas.
Check sealing performance frequently to prevent air leakage.
Examine wear condition of electrodes and collecting plates and replace worn parts timely.
As essential waste gas purification equipment, electric tar precipitators can efficiently eliminate hazardous substances in exhaust gas and protect ecological environment and public health.

Performance Characteristics
Under all operating conditions, the equipment enables high voltage to operate below the critical spark initiation point through automatic tracking, maintaining stable electric field strength for sufficient particle charging. Its tar removal efficiency reaches over 99.8% with remarkable economic benefits.
The electric control system supports automatic tracking protection. It will cut off power supply automatically and trigger sound-light alarm in case of load short circuit, overcurrent and excessive oxygen content to guarantee safe production.
High-voltage silicon rectifier is mounted on the tower top, featuring high safety and reliability. Short high-voltage cables effectively reduce failure rate.
Easy for installation, commissioning and maintenance, low maintenance cost, stable operation and wide matching adaptability.
The discharge electrode adopts three-point suspension structure, which reduces load on single-point high-voltage porcelain insulator and system swing, greatly improving overall balance and stability.
Low power consumption of electric system with clear control display and simple operation.
Honeycomb and concentric circle structural designs are adopted for compact layout, low internal flow resistance and long service life.
Equipped with steam heating and thermal insulation system to ensure stable working performance of high-voltage porcelain insulators.
Fitted with steam purging system, heating device, flushing unit and sewage outlet, facilitating regular maintenance, decontamination and sewage discharge.
