Waste gas washing purification tower

Waste gas washing purification tower

Process flow description
(1) Advantages and characteristics: On the basis of many years of design and manufacturing experience, advanced technology from the United States is introduced to form a new generation of technical purification equipment. The main advantages are as follows:
Adopt air inlet turbulent design structure (there is no such function in the same industry);
Adopt practical quick-response supplementary device for air inlet (there is no such function in the same industry);
The jacketed distributed exhaust gas channel is adopted (few in the industry have this function) to improve the uniform distribution of the exhaust gas, increase the reaction time of the exhaust gas flow, and greatly improve the residence time of the exhaust gas in the tower (the exhaust gas from the same industry generally goes straight up after entering the tower, and the distribution uneven, insufficient reaction, low processing efficiency);
The spray system is fully covered, the gas-liquid contact is sufficient, the counter-current washing has no dead ends, and the reaction is sufficient (increases the time for the gas-liquid phase to fully contact and react, and the treatment effect is far greater than similar equipment from other companies); Small floor area, good corrosion resistance, good aging resistance, light weight, easy transportation, installation, management, operation and maintenance, etc., and higher purification efficiency;
After the exhaust gas enters the equipment, it is evenly distributed around the built-in PP Terrary barbed garland + PP multi-faceted hollow sphere alternate packing layer, arranged in an irregular "Z or W" route, without bias flow phenomenon, and combined with spiral high flow, no blockage Nozzle, the mixing rate of gas-liquid two-phase is more than 97%, and it is discharged after deliquoring and de-fogging by the deliquor; The equipment is equipped with acid-alkali-resistant corrosion-resistant vertical circulating pump + automatic dosing system to ensure the control of circulating spray liquid range of pH values.
(2) Application fields: It is mainly used in the treatment of acid and alkali waste gas and the pretreatment of organic waste gas to treat high concentrations of nitrogen oxides (NOx), hydrogen sulfide (H2S), sulfur dioxide (SO2), nitric acid mist (HNO3), Hydrochloric acid mist (HCl), sulfuric acid mist (H2SO4), hydrofluoric acid mist (HF), ammonia gas (NH3) and other acid-base exhaust gas and other mixed exhaust gas streams.
