Next-generation WESP allows for faster installation times

By Mary Page Bailey and Gerald Ondrey |

This company recently released a new wet electrostatic precipitator (WESP) that controls air pollution by removing fine particulate matter, acid mists and aerosols from industrial gas streams. In designing the new system, strong focus was placed on the system’s high-intensity, offline automatic cleaning features, which reduce maintenance efforts, eliminate carryover of entrained matter during washing and provide better operational performance during cleaning. System components are also now easily accessible for maintenance inspections. Efficient contaminant capture is achieved through increased operating voltage, which requires less collection surface area. Additionally, the gas-distribution system can optimize flow through the system, and various tube shapes and electrodes were tested to improve overall performance. WESPs can remove up to 98% of particulate matter in a single stage, depending on the characteristics of the gas stream. Standardized modules are used in the new design, reducing installation time and streamlining fabrication. Tube bundles come pre-assembled, and electrodes are pre-loaded and pre-aligned. — Dürr Megtec, De Pere, Wis.
