Our DGS-B systems provide you with high-performance, reliable solutions for demanding industrial environments:
Corrosion-Resistant Materials: Built with FRP for harsh acidic and alkaline conditions.
High Removal Efficiency: Optimized spray system, structured packing, and demisters maximize gas-liquid contact.
Energy-Efficient and Low Noise: Operates quietly while consuming minimal energy.
Process-Specific Design: Tailored to your gas composition, concentration, and facility layout.
Gas Handling Capability: Efficiently treats HF, HCl, H2SO4, H2S, NH3, NaOH, HCHO, CrO3, HCN, and other water-soluble acidic, alkaline, or mixed gases.
Reliable and Stable Operation: Maintains performance under continuous, high-concentration exhaust conditions.
Designed in accordance with ASME RTP-1 standard and manufactured in accordance with ASTM 3299D standard.
Our DGS-B industrial wet scrubbers are ideal for handling corrosive and high-concentration gases in your facility.
They are widely used in:
Chemical and petrochemical plants: controlling acid and alkali emissions from production lines.
Electroplating and metal surface treatment: managing plating and pickling fumes efficiently.
Solar and semiconductor manufacturing: safely removing acid mist from wafer cleaning processes.
Boilers and industrial furnaces: treating corrosive gases in energy generation systems.
Electronics and instrumentation manufacturing: ensuring clean exhaust in sensitive production areas.

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.
