Electrost atic Precipit ators of Compact DesignElectrost atic Precipit ators of Compact DesignElectrostatic precipitators EKO of compact design are intended for the separation of solid particles from small

sources of dust pollution, with a fl ow rate of 3 000 to 40 000 m³/h. They consist of several compact functional units delivered to the construction site fully assembled. Their sizes can be selected with regard to transport possibilities. The workshop assembly of the functional parts guarantees the high quality of delivery and shortens the time of site installation.

The electrostatic precipitators EMO of modular design are used for separation of solid particles from middle and large sources of dust pollution with the fl ow rate above 15 000 m³/h.

They are put together from smaller modules, transported to the construction site in installable parts and assembled there to the fi nal unit size.

Electrostatic precipitators EKF, EKG, EKH and EKK are supplied within a wide size range, which is always determined by the combination of width, length and height of the active space of electrostatic precipitators.

Inner active parts of electrostatic precipitators are designed so that they can be used for repair works and reconstruction works of all available types of electrostatic precipitators of local and foreign production.

ZVVZ-Enven Engineering, a.s. supplies dry chamber horizontal electrostatic precipitators (hereinafter referred to as electrostatic precipitators – ESP) of its own design under the trademark EKO, EMO, EKF, EKG, EKH, EKK. These electrostatic precipitators are highly effi cient and reliable equipment for separation of solid contaminants from waste and technological gases. Their high effi ciency guarantees very low outlet emission of solid pollutants into the environment and it fully complies with the strictest environmental protection laws. These electrostatic precipitators are successfully used in power plants, heating plants, waste incinerators, in cement and lime industries, in metallurgical works, as well as in the chemical industry and other areas producing solid pollutants.

Principle of Electrost atic SeparationPrinciple of Electrost atic SeparationThe active area of the electrostatic precipitator consists of a system of high voltage discharge and collecting

electrodes, geometrically arranged with specifi ed spacing. The discharge electrodes are fed with direct negative current of very high voltage, 30–100 kV, collecting electrodes are grounded. Due to such very high voltage application to discharge electrodes, a strong electric fi eld is generated between discharge and collecting electrodes and so called corona discharge (large quantity of negative ions) occurs in the surrounding space of discharge electrodes. The dust particles contained in the gas stream passing through the active space between the discharge and collecting electrodes are charged (bombarded) with negative ions and thereby they get considerable negative charge. Through the effect of the strong electric fi eld, the charged particles are attracted to the surface of collecting electrodes where they are deposited. The mechanical rapping releases the deposited dust off the collecting electrodes, which is sliding along the surface of collecting electrodes and falling into the hopper of electrostatic precipitator, where it is continuously removed from to be further used or stored.

Suspension and RappingThe discharge electrodes are fi xed in tubular frames by means of bolts or

by welds. The system of discharge electrodes of each fi eld is electrically separated from earthed parts of the casing by means of porcelain conic insulators.

Individual frames of discharge electrodes and the electrodes themselves are cleaned by mechanical rapping, which is ensured by lifted hammers fastened to the shaft. The rapping is carried out in regular, programmed intervals.

Collecting ElectrodesCollecting ElectrodesCollecting electrodes have been designed to be suffi ciently rigid

and at the same time to utilize as much as possible the enveloping impact cycles of the corona discharges from the discharge electrodes. They are manufactured by cold rolling of deep-drawing sheet metal, 1.2 to 1.5 mm thick.

Profi le Types of Collecting Electrodes:• C1 (width 640 mm – applicable to EKO, EMO, EKK);• C2 (width 500 mm – applicable to EKO, EMO, EKK);• V1 (width 640 mm – applicable to EMO, EKH, EKK);• CS11 (width 640 mm – applicable to EKH);• CS1 (width 640 mm – applicable to EKG);• SCS (width 640 mm – applicable to EKF);• CSH2 (width 480 mm – applicable to EKE).

Suspension and RappingThe collecting electrodes are fi xed to suspension beams loosely

on pins. They are joined together in the rapping beam by means of a pre-stressed riveted joint. Both the fi rm bottom and the top loose attachment provide for a perfect transfer

of energy from the rapping hammers to the entire row of collecting electrodes. The rapping is carried out in regular, programmed intervals and guarantees removal of deposited dust from the electrodes to the hoppers.
