        \n

        The WESP Working Principle<\/h3>\n

        Unlike dry ESPs, the Ever-power WESP operates in a fully saturated gas environment (below dew point). It is specifically engineered to capture liquid aerosols, SO3 acid mists, and sticky dusts that would blind dry mechanical filters.<\/p>\n

        \"Wet<\/p>\n

          \n
        1. High-Voltage Ionization:<\/strong> Tens of thousands of volts of DC high voltage are applied between the Anode Tube and Cathode Wire. The intense electric field fully ionizes the saturated gas, generating massive quantities of electrons and ions.<\/li>\n
        2. Particle Charging:<\/strong> As dust-laden gas flows through, these ions collide with fine dust particles, droplets, and aerosols, heavily charging them.<\/li>\n
        3. Electrostatic Migration:<\/strong> Driven by Coulomb force, the charged particulate separates from the airflow and migrates rapidly toward the grounded Anode Tube inner wall.<\/li>\n
        4. Continuous Flushing:<\/strong> Adsorbed particles are trapped in a continuous water film. A Flushing System<\/strong> washes the tubes, allowing the slurry to flow into the lower liquid zone via gravity. No mechanical rapping is used<\/strong>, eliminating secondary dust entrainment.<\/li>\n<\/ol>\n

          Advanced Internal Components<\/h3>\n

          Handling wet, corrosive, acid-rich gases requires exceptional material science and structural engineering:<\/p>\n

            \n
          • Anode Tubes:<\/strong> Manufactured from either Conductive Fiberglass (FRP) Honeycomb<\/strong> ou 2205 Duplex Stainless Steel Honeycomb<\/strong>. These materials offer flawless electrical conductivity combined with absolute immunity to sulfuric and hydrochloric acid corrosion.<\/li>\n
          • Cathode Wires:<\/strong> Tailored to the flue gas chemistry, we deploy Lead-Antimony alloy, 2205 SS barbed, or tubular barbed wires. These provide a sharp, intense corona discharge and are anchored by our rigid Tensioning Device<\/strong> to prevent sway and shorting.<\/li>\n
          • Insulator Box:<\/strong> The most critical failure point in any WESP is high-voltage tracking over wet insulators. Our system utilizes a sealed, heated Insulator Box<\/strong> acting as a “protective umbrella,” ensuring high voltage is safely introduced without grounding out in the humid environment.<\/li>\n
          • High-Frequency Power Supply:<\/strong> Delivers rapid micro-pulses of DC voltage, adapting instantly to changes in gas moisture and minimizing spark-over energy.<\/li>\n<\/ul>\n

            ? Strategic Engineering Advantages<\/h2>\n
            \n
            \n

            Zero Secondary Entrainment<\/h3>\n

            Because the WESP uses a water film and flushing system instead of mechanical hammers (rapping), collected dust is permanently trapped in liquid. It is physically impossible for dust to re-enter the gas stream, securing your ultra-low emission guarantees.<\/p>\n<\/div>\n

            \n

            Total Plume & Mist Eradication<\/h3>\n

            Standard wet scrubbers fail to capture aerosols smaller than 2 microns. The Ever-power WESP captures sub-micron PM2.5, SO3 acid mists, and heavy metals, effectively eliminating the dreaded “blue plume” or “yellow plume” at your stack outlet.<\/p>\n<\/div>\n

            \n

            Low Resistance = Low OPEX<\/h3>\n

            Despite its massive capture efficiency, the aerodynamic open-tube design yields a system resistance of only 300 – 500 Pa<\/strong>. This saves massive amounts of ID fan electricity compared to high-energy venturi scrubbers.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

            \n

            The Post-FGD Carryover Crisis<\/h3>\n

            Many industrial plants install Wet Flue Gas Desulfurization (WFGD) scrubbers and assume compliance is met. However, scrubbers inherently generate microscopic gypsum droplets and saturated acid mists that pass right through standard mechanical mist eliminators. This “acid rain” violently corrodes downstream ductwork, destroys chimney stacks, and creates highly visible, legally non-compliant plumes. A WESP is the mandatory final gatekeeper to protect your infrastructure.<\/p>\n<\/div>\n

            \n

            Extreme Regulatory Pressure on PM2.5<\/h3>\n

            Global environmental protection agencies are moving past TSP (Total Suspended Particulates) and strictly enforcing PM2.5 and PM1.0 limits. Fabric filters and dry ESPs cannot capture sticky, ultrafine saturated aerosols. WESP technology is the only commercially viable method proven to consistently achieve outlet concentrations below 5 mg\/Nm3 for these complex streams.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

            ? Typical Application Scenarios & Industry Fit<\/h2>\n

            Lithium & New Energy Materials<\/h3>\n

            Crucial for Lithium Carbonate calcination and roasting exhaust. Captures valuable product dust that escapes dry collection systems while resisting highly corrosive chemical byproducts generated in battery material processing.<\/p>\n<\/div>\n

            \n

            Metallurgy & Calcination<\/h3>\n

            Purifies off-gases from steel sintering, lead\/zinc roasting, and new wall material workshops. Captures heavy metals, sticky tars, and condensed acids that would permanently blind traditional fabric filters.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
