Wet Electrostatic Precipitator
Wet electrostatic precipitator for deep dust, mist and aerosol removal in ultra-low emission flue gas treatment projects.
Wet Electrostatic Precipitator for pollution-control projects
Wet electrostatic precipitator for deep removal of fine dust, acid mist, tar mist and wet flue gas aerosols after desulfurization or high-humidity treatment sections.
Wet electrostatic precipitator equipment is discussed when ordinary bag filtration or spray washing is not enough for fine dust, acid mist, tar mist or high-humidity flue gas polishing.
The WESP document lists air volume from 5000 to 150000 m3/h, dust and mist removal efficiency >=99%, outlet dust <=5 mg/m3, operating resistance around 300-600 Pa and DC high-voltage power supply around 30-80 kV.
Equipment data from supplied material
This table keeps the equipment values, routes and material options stated in the supplied product material. Selection notes and related-product links elsewhere on the page are website guidance, not added hard specifications.
Supplied wet electrostatic precipitator performance material. Final sizing still depends on site conditions, but the values in this table are kept to the supplied material.

Configured around the actual treatment route
The treatment route is confirmed from the supplied equipment material, then sized by air volume, water volume, pollutant type, material requirement and site layout.
Project-specific wastewater, exhaust gas or pollution control applications
Air volume, water volume, pollutant type, temperature, humidity, corrosion and inlet condition affect configuration.
Treatment body, fans, ducts, pumps, control cabinet, safety protection and maintenance access are reviewed by route.
Hard parameters are kept to supplied product material; final sizing is confirmed by project condition.
Selection notes kept separate from source parameters
Huisheng reviews the treatment route, handled medium, capacity, material, outlet target and auxiliary systems before confirming a configuration. Documented values remain in the technical data table, while project pairing and monitoring-interface notes are treated as selection guidance.
Hard values are kept to the supplied product material. Project-specific sizing is treated as selection work, not as a new published parameter.
Exhaust gas, dust, odor, flue gas polishing or wastewater condition should be confirmed before choosing the treatment route.
Air volume, water volume, pollutant load and outlet requirement determine final equipment sizing.
Q235, 304 stainless steel, FRP, PP or anti-corrosion options are selected according to the documented material scope and site condition.
Fans, ducts, pumps, control cabinets, safety protection and monitoring interfaces are discussed as configuration notes.
Parameters and scope stated in supplied material
The items below summarize capacity, material, process route, efficiency or equipment-scope information from the supplied product material. Extra project advice stays in selection notes instead of becoming a published hard parameter.
