OPTIMAL DIMENSIONING
Based on years of experience and its leading-edge engineering design skills, AIR PROCESS SOLUTIONS designs and supplies electrostatic precipitators that are tailor-made to suit customer needs. They therefore operate at the best cost-benefit ratio, which is ensured by reliable calculations based on many years of experience and an extensive database from numerous installations.
HOW THE AIR PROCESS SOLUTIONS / ELEX ELECTROSTATIC PRECIPITATOR WORKS
The principle of the AIR PROCESS SOLUTIONS / ELEX Electrostatic Precipitator is based on well-proven technology. Electrons are emitted from discharge electrodes, which have been charged with a rectified negative high voltage. These electrons migrate to the collecting electrodes and, as the electrons accumulate on the dust particles, the latter become negatively charged. The electric field transports them to the earthed collecting electrodes where they are deposited.
In the AIR PROCESS SOLUTIONS / ELEX Electrostatic Precipitator, the collecting electrodes consist of profiled plates. These form a system of passages through which exhaust gas flows. Robust discharge electrodes are arranged along the central axis of the 400 mm wide passages. Mechanical rapping equipment cleans the collecting electrodes by means of periodic rapping. The robust electrodes and the maintenance-friendly design are only two of the AIR PROCESS SOLUTIONS / ELEX Electrostatic Precipitator’s main characteristics.
ELEX ELECTROSTATIC PRECIPITATORS
The AIR PROCESS SOLUTIONS / ELEX Electrostatic Precipitator is the most economical system available for removal of dust from industrial gases. Operating costs are reduced due to low energy consumption and the cost of maintenance and spare parts is low. In addition, life expectancy of electrostatic precipitators usually exceeds that of upstream production units, such as kilns, mills, driers and coolers.
AIR PROCESS SOLUTIONS / ELEX Electrostatic Precipitators are capable of reducing dust content of more than 1,000 g/m3 to any required residual dust content
