Experimental research on ammonia removal performance of anion air purifiers

An experimental research on the effectiveness of ammonia removal by the anion air purifier is carried out. The relationships between ammonia removal efficiency and windward air velocity, external voltage and initial ammonia concentration are studied on the air duct purification platform, and the effectiveness of the anion air purifier in removing ammonia is tested in an environmental laboratory. The results show that the anion air purifier can effectively remove ammonia. When other conditions remain unchanged, the ammonia removal efficiency of the anion device decreases with the increase of wind speed, firstly increases and then decreases with the increase of external voltage, and firstly increases and then gradually decreases with the increase of initial ammonia concentration. The influence of each factor on ammonia removal efficiency is wind speed, initial ammonia concentration and voltage in descending order.
