Dürr unveils ‘next-gen’ pollution control

More efficient contaminant capture was achieved through increased operating voltage that requires less collecting surface area. The gas distribution system was completely reimagined to optimise flow through the system.

Dürr Megtec recently released its “next generation” wet electrostatic precipitator (WESP), an air pollution control system that efficiently cleans industrial gases of fine particulate matter, acid mists and aerosols to meet global environmental regulations and protect downstream equipment.

Key improvements of this advanced WESP system include decreased maintenance, enhanced performance, standardisation and faster installation times. System components are also now easily accessible for maintenance inspections.

Dürr Megtec designed the new WESP with both the environment and its customers’ operations and maintenance teams in mind. As a result, a 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.

Dürr achieved a more efficient contaminant capture through increased operating voltage that requires less collecting surface area. Additionally, the gas distribution system was completely reimagined to optimise flow through the system, and various tube shapes and electrodes were tested to improve overall performance.

Standardised modules are used in the new design, thus reducing engineering time and streamlining fabrication. The systems are assembled from different standard modules and adapted to customer-specific requirements.

Modules with tube bundles are pre-assembled in the production facility for shipment to the customer. All electrodes are pre-loaded and pre-aligned, thus avoiding this lengthy and tedious task on the construction site.

WESP air pollution control systems are used in all sectors of industry, including wood, waste incineration, food processing, bio-fuels, metals and mining, chemical, petrochemical, iron and steel, and pulp and paper.

Dürr WESPs can remove up to 98% of particulate in a single stage, depending on the characteristics of the gas stream. Increased removal efficiency is possible with alternative configurations.
