WPT + WESP Technology

WPT + WESP fine dust removal technology, also known as improved phase change coupling electrostatic fine dust removal technology, is the coupling technology of ultra-fine particle coagulation technology (WPT) and wet electrostatic precipitator (WESP), which is an effective way to realize ultra-low emission terminal control of flue gas. Through the mechanism of phase transformation and condensation, the particles can be effectively coagulated and "grow up" to achieve efficient removal, and the removal efficiency of PM2.5 can reach more than 95%. It can effectively remove fine particles (PM2.5 dust, SO3 acid fog, aerosol) and heavy metals (Hg, as, Se, etc.), reduce dust emission to less than 5mg / Nm3, and effectively reduce flue gas white tail.

Technical features:

             (1) Conductive glass fiber reinforced plastic or 2205 bidirectional stainless steel shall be used as the dust collecting electrode tube with modular structure and honeycomb arrangement, which can effectively utilize the space and evenly distribute the flow field. Better dust removal effect shall be realized by good corrosion resistance, strong and stable discharge, and relative high voltage and current parameter and so on.

            (2) Flexible structure to adapt to complicated sites as it can be installed to the exhaust flue of the desulfurizing tower, the top of the tower or the other allowable areas in the power plant without being attached to the other equipment.

            (3) High-voltage constant flow power source and sparkle control device will be used to avoid electric flicker and arc to ensure the stable operation of the power plant.
