Acetylene stripping tower equipment

Acetylene stripping tower equipmentworking principleAmmonia nitrogen in wastewater mainly exists in the form of ammonium ions (NH4) and free ammonia (NH3), and its equilibrium relationship is as follows: NH3 H2O - NH4OH - This relationship is affected by pH value. When the pH value is high, the equilibrium shifts to the left and the proportion of free ammonia increases. At room temperature, when the pH value is around 7, most of the ammonia nitrogen exists in the form of ammonium ions, while when the pH is around 11, free ammonia accounts for approximately 98%. Free ammonia is easy to escape from water, and if aerated, it can promote the escape of ammonia from water. Among them, pH is the key to the effect.

The application scenarios of acetylene stripping tower equipment include:

Fertilizer plant wastewater: Treatment of ammonia nitrogen containing wastewater generated during the fertilizer production process.

Garbage leachate: Treatment of leachate generated from landfills.

Petrochemicals and refineries: treat wastewater containing ammonia nitrogen generated during the petrochemical and refining processes.

Acetylene stripping tower is a device used for treating wastewater containing ammonia nitrogen, widely used in fertilizer plant wastewater, garbage leachate, petrochemical, refinery and other occasions. Its working principle is to remove ammonia nitrogen from wastewater through blow off method. Specifically, ammonia nitrogen waste gas enters the purification tower through the air inlet below the tower body. Under the power of the ventilation fan, it uniformly passes through the packing absorption section and the spray section. The ammonia gas in the gas phase reacts with water or sulfuric acid in the liquid phase to produce NH3-OH or (NH4) 2SO4, which then flows into the lower storage tank. The unabsorbed ammonia continues to rise and enter the spray section, where it further mixes and comes into contact with the absorbing liquid, resulting in a chemical reaction. Finally, the absorbing liquid droplets in the gas are removed in the dehazing section, and the treated clean air is discharged into the atmosphere through the exhaust pipe at the upper end of the purification tower.
