The Packed Bed Wet Scrubber system achieves high purification efficiency for HNO3, NOx, HF, HCl, H2SO4, and NH3, ensuring stable acid gas removal in industrial exhaust gas applications.
| Ingredient | Concentration mg/m3 | Purification efficiency % | Neutralizing and absorbing solution |
| HNO3 | ≤200 | ≥95 | 2–7% NaOH liquor and 3–4% Na2S liquor |
| NOx | ≤2000 | ≥95 | 7% NaOH liquor and 3–4% Na2S liquor |
| HF | ≤400 | ≥95 | 2–7% NaOH liquor |
| HCl | ≤400 | ≥98 | 2–7% NaOH liquor |
| H2SO4 | ≤400 | ≥95 | 2–7% NaOH liquor |
| NH3 | ≤4000 | ≥99 | Water solution or 2–7% NaOH liquor |
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.
