ESP Electrostatic Precipitator for Sale
The esp electrostatic precipitator, also called an industrial electrostatic precipitator, is a common dust removal equipment in industrial production. It mainly uses high-voltage static electricity to remove dust particles in the gas. The dust removal efficiency of the esp electrostatic precipitator is over 99% and can withstand temperatures over 400°C. In the lime production line, ESP can effectively capture fine particles such as CaO and CaCO₃to meet strict environmental emission standards.
AGICO has provided professional electrostatic precipitator solutions for lime production lines, cement plants, power plants, metallurgy, and other industries. We also continuously develop equally efficient baghouse dust collectors and industrial cyclone dust collectors to meet customers’ different demands.
Advantages of ESP Electrostatic Precipitator
High Dust Removal Efficiency
The esp electrostatic precipitator can capture more than 99% of the fine particles of 0.1~20μm. The dust concentration at the outlet can be controlled below 10mg/m³, fully meeting the emission standards.
Low Energy Consumption
The pressure drop of airflow through the esp electrostatic precipitator is only 100~300Pa. Compared with a baghouse dust collector, the fan energy consumption is reduced by 30%~50%.
High-temperature Resistance
ESP electrostatic precipitator can handle high-temperature flue gas ≤400℃, and can reach 500℃ in special cases. It can adapt to corrosive components such as SO2 and HCl in flue gas.
Large air Volume
The flue gas treatment capacity of a single esp electrostatic precipitator has reached 200X104m3/h. It also supports continuous operation, without the need to stop for cleaning and without the risk of blockage.
Working Principle of ESP Electrostatic Precipitator
An industrial electrostatic precipitator typically consists of collecting electrodes/plates, discharge electrodes, inlet and outlet perforated screens, discharge electrode insulators, rappers, and one or more power transformers.
1. Ionization and charging: There are usually discharge electrodes and dust collecting electrodes inside the industrial electrostatic precipitator. The discharge electrode is connected to the negative electrode of the high voltage DC power supply, and the dust collecting electrode is connected to the positive electrode. When the electric field strength is large enough, the air molecules near the electrode will be ionized, generating a large number of free electrons and positive ions.
2. Dust charging: Flue gas containing dust particles enters the industrial electrostatic precipitator and continuously collides with free electrons and ions. The free electrons attach to the surface of dust particles during their rapid motion.
3. Electric field capture: Negatively charged dust particles will move toward the positively charged dust collecting plate under the action of the electric field force. When reaching the dust collecting plate, the dust particles lose their charge and are adsorbed on the surface of the dust collecting plate.
4. Dust cleaning and collection: A dust layer will gradually form on the dust collecting plate. The dust on the collecting plate is cleaned by vibration, so that the dust falls into the ash hopper below and is finally collected and processed.
Dry Esp Electrostatic Precipitator VS Wet Esp Electrostatic Precipitator
—— AGICO’s esp electrostatic precipitator is your best choice!
Dry ESP
- Cleaning method: The dust is mainly cleaned by mechanical vibration so that the dust falls into the ash hopper below.
- Applicable flue gas characteristics: It is suitable for treating dry flue gas with higher temperatures and less or no water content.
- Advantages: no wastewater production, simple structure, and low maintenance cost.
- Disadvantages: Vibration may cause secondary dust.
Wet ESP
- Cleaning method: mainly through water film or spray water to form mud and be discharged.
- Applicable flue gas characteristics: Suitable for treating flue gas that is wet and saturated, contains a lot of water vapor, or contains acid mist, fine particles, heavy metals, and sticky dust.
- Advantages: No secondary dust and the inside of the equipment is not prone to scaling and corrosion.
- Disadvantages: It will produce wastewater, the internal humidity is high, and the anti-corrosion requirements are higher.

Application in lime production line
——The temperature of the flue gas at the kiln tail produced by lime calcination is relatively high, and a large amount of dust will be generated in the processes of limestone crushing, kiln entry, calcination, and quicklime exiting the kiln.
The flue gas generated by the lime kiln must be treated by dust removal equipment before being discharged to meet the emission standards. Esp electrostatic precipitator has the characteristics of large air volume, small operating resistance, and high dust removal efficiency. Therefore, it is often used to treat kiln tail gas.
In the case of high flue gas temperature, dust density, and moderate resistance, a dry esp electrostatic precipitator is a common choice. And the recovered dust can be reused as raw material.
Some lime production lines have a desulfurization process. The flue gas after desulfurization is usually in a wet saturated state. The wet esp electrostatic precipitator is not affected by dust resistivity and avoids secondary dust.
