Electrostatic filter

We have acquired an exclusive representation of SaveEnergy for the Czech and Slovak Republics. SaveEnergy is a manufacturer of electrostatic precipitators based in Switzerland. The electrostatic precipitator is used for dedusting flue gases from combustion sources. Use for solid fuel boilers or biomass boilers with higher outputs than approx. 2MW. Electrostatic precipitators are effective means for dedusting flue gases from continuously operated combustion sources. Electrostatic precipitators have a low pressure drop, which does not change in relation to the dustiness of the flue gases.

The SaveEnergy dry electrostatic precipitator is a high-capacity separator, which was developed with the specific goal of achieving minimum operating costs and maximum efficiency of TZL separation of around 99%. In a dry SaveEnergy electrostatic precipitator (commonly known as an electrostatic precipitator), the particles are separated from the flue gas by the force of an electrostatic charge. Electrically neutral dust particles are charged by discharge electrodes. The force of the electric charges sends the particles towards the collecting electrode and thus separates them from the gas stream.

The SaveEnergy dry electrostatic precipitator is a plate construction. A controlled high-voltage field with a voltage of up to 70 kV is generated on the discharge electrodes. A high field strength is generated directly around the discharge electrodes. In this core, free electrons are highly accelerated (gas discharge). This so-called ionization is associated with mild radiation. The discharge at the ends of the discharge electrodes creates gas ions which adhere to the dust particles and give them an electric charge.

Electrostatic precipitator function


The charged particles are then drawn into a separation chamber through which the gas flows and transported in the direction of the gas flow between the discharge and collecting electrodes to the electrically grounded collecting plates (anodes) and are thus separated from the purified gas stream.

This flow, which moves from the core through the passive zone to the collecting electrode, is known as “electric wind”.

Dust collection in the electrostatic precipitator


The separated particles form a layer of dust on the collecting plates. Because the collector plates are grounded, the dust particles lose charge and can be mechanically cleaned. Hammer blows. Hammer blows are cycled at various preset intervals to both the collection plates and the frames of the discharge electrodes.

The dust particles are released by mechanical shock waves and fall into the collecting tanks. The cycle of dust ionization, its capture and separation from the flowing gas works continuously during the operation of the boiler.
