Overview
DGS-B-type fiberglass Industrial wet scrubbers is the company under foreign gas processing equipment and processing company based on the mist of a new generation of acid mist treatment equipment to improve the resistance of the device small, the energy province, low noise, high efficiency . Can handle hydrofluoric acid (HF), hydrochloric acid mist (HCL), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), hydrogen cyanide (HCF), hydrogen sulfide (H2S), ammonia (NH3), alkali vapor ( NaOH) formalin (HCHO) and other acid-alkali water-soluble mixture of gas and gas. After several years of using it, purified exhaust emission standards to Shanghai, below the national emission standards GB16279-1996 "Integrated emission standard of air pollution."

Installation size and foundation
Process principle of industrial waste gaswet 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.
