High-Efficiency Packed Bed Wet Scrubber

Engineered for broad-range mixed acid and soluble gas streams, the DGS-B Packed Bed Wet Scrubber delivers 30–70% higher removal efficiency with patented internal design that eliminates channeling and maximizes gas-liquid contact. Designed for stable, low-resistance operation across variable industrial conditions.

Technical Strengths

1
30–70% higher removal efficiency than conventional scrubbers under varying gas concentrations.
2
Low Resistance & energy-saving: optimized internal flow reduces pressure drop and lowers operational costs.
3
Broad Gas Compatibility: handles acids, bases, low-concentration NOx, and water-soluble gases without performance loss.
4
Stable Continuous Operation: maintains consistent performance across fluctuating flows and gas loads.
5
Easy Integration & Customization: adaptable to flow rate, gas composition, and chemical dosing.
6
Reliable Maintenance Profile: robust design minimizes downtime and simplifies routine checks.

Process Principle of Industrial Waste Gas Wet Scrubbers

Under the action of the fan, the exhaust gas reaches the bottom packing bed, enters the pressure balancing room formed by the internal and external jacket at a low speed, and is transported by circulating pump and washed countercurrent. The exhaust gas is evenly distributed around the PP Terary barbed garland +PP multi-sided hollow ball alternating packing layer, each showing point contact, arranging "Z or W" irregular route walking, without bias phenomenon. Then with the spiral high flow, not blocking the nozzle, so that the gas-liquid two-phase mixing rate of more than 97%, so that the exhaust gas to get the gas-liquid two-phase full contact reaction, and then through the deliquid defogging, to meet the national GB16297-1996 "comprehensive emission standards for air pollutants" in the secondary emission requirements, and finally through the exhaust pipe into the atmosphere.
