EHWD-DVFH combines Venturi pre-scrubbing, self-induced wet dust collection and downstream filtration for difficult industrial dust conditions.

The Venturi section improves gas-liquid contact at the inlet and provides pre-treatment before the airflow enters the main wet collection stage.

The Venturi module can be integrated with suitable EHWD wet dust collector configurations according to the required airflow and process conditions.

Sludge can be further treated by a filter press to separate captured solids and recover clarified water for reuse in the wet collection process.

Main components include the Venturi scrubbing section, self-induced wet collection structure, liquid-level control system, water tank and corrosion-resistant equipment materials.

High-velocity airflow through the Venturi section generates intensive gas-liquid contact for pre-scrubbing before the dust-laden air enters the main wet collection chamber.

The self-induced wet stage uses controlled water turbulence to capture particulate without spray nozzles in the main collection section.

Multi-stage treatment combines Venturi scrubbing, wet dust collection and downstream filtration to improve overall particulate removal performance.

Typical applications include steel processing, chemical production, quarrying, material handling and other processes involving high dust loading, heat, moisture or difficult dust conditions.

Closed-loop water treatment can be configured with sludge separation equipment to reduce fresh-water consumption and support water reuse, subject to process conditions and local discharge requirements.
