目前煙氣脫硝技術可分為干法和濕法兩大類，其中干法脫硝中的選擇性催化還原（SCR）和選擇性非催化還原（SNCR）技術是很普通的脫硝技術，其原理是向煙氣中噴氨或尿素等含有NH3?自由基的還原劑，在高溫下直接（或催化劑的協(xié)同下）與煙氣中的NOx發(fā)生氧化還原反應，把NOx還原成氮氣和水。但該技術也有其巨大的局限性，由于化學反應需要在高溫下進行，而對于中小型鍋爐以及工業(yè)鍋爐來說，排煙溫度遠不能達到化學反應所需要的高溫，低溫煙氣脫硝技術就成為市場的必須。
臭氧脫銷原理；是將不溶于水的低價態(tài)氮氧化合物，通過臭氧的高級氧化性，氧化為可溶的高價態(tài)氮氧化合物，然后在噴淋洗滌塔內，通過堿性溶液進行吸收。達到脫除的目的。
低溫煙氣脫硝技術以低溫催化氧化技術（LoTOx）zui為簡單有效，由于煙氣中的氮氧化物主要組成是NO（占95%），NO難溶于水，NO與臭氧接觸后，發(fā)生反應，可成生成NO2、NO3、N2O5等高價態(tài)的氮氧化全物，這些高價態(tài)的氮氧化合物可溶于水,生成HNO2和HNO3，溶解能力大大提高，很容易通過堿性溶液噴淋(如Ca(OH)2、NaOH)等手段將其從煙氣中脫出。將煙氣中的NO轉化為高價態(tài)，需引入較強的氧化劑，在眾多氧化劑中，臭氧是zui環(huán)保清潔的強氧化劑，在高效轉化NO至高價態(tài)的過程中不遺何二次污染物，另外不同于?OH、?HO2 等，工作環(huán)境惡劣，自由基存活時間非常短，能耗較高，O3的生存周期相對較長，將少量氧氣或空氣電離后產(chǎn)生O3，然后送入煙氣中，可顯著降低能耗。
Electrostatic air purifier using the ionized gas molecules in the air high voltage DC electric field, resulting in a large number of electrons and ions, under the action of electric field force to move toward the poles, with dust particles and bacteria in the air in the process of moving the charged, the charged particles under the action of electric field force to its opposite charge plate do movement in the electric field, the free ions in the air to move to the poles, the higher the voltage, the electric field intensity is high, the faster the movement of ions. Due to the movement of ions, a current is formed between the poles. At the beginning, the free ions in the air were less and the current was less. When the voltage rises to a certain value, the ions near the discharge electrodes get higher energy and speed. When they hit the neutral atoms in the air, the neutral atoms will be decomposed into positive and negative ions, which is called air ionization. The air ionization, the chain reaction, greatly increased in the number of ion motion, as current between the electrodes (called corona current) increased dramatically, the air became the conductor, high voltage with bacterial cell wall particle capture, instant conductive breakdown composed of protein, to kill bacteria adsorption dust.
