【摘要】：為了解高壓電暈放電與液相化學(xué)氧化協(xié)同脫硝的影響因素與機(jī)理,研究了在高壓電暈放電與液相化學(xué)氧化的協(xié)同作用下,供電電壓、水體積流量、吸收劑種類以及NO初始質(zhì)量濃度、煙氣體積流量等因素對(duì)脫硝效率的影響,探討了高壓電暈放電與液相化學(xué)氧化協(xié)同脫硝的機(jī)理。NO氣體經(jīng)流量計(jì)與空氣混合形成模擬氣體,輸送至反應(yīng)器內(nèi)進(jìn)行反應(yīng)后排放。測定NO質(zhì)量濃度,計(jì)算煙氣脫硝效率。結(jié)果表明:脫硝效率隨著供電電壓、水體積流量、吸收劑濃度的增加而增加,但隨著NO初始質(zhì)量濃度、煙氣體積流量的增加而下降。在3 k V高壓電暈放電和質(zhì)量分?jǐn)?shù)為5%的H_2O_2協(xié)同作用下,煙氣脫硝效率高達(dá)60.2%。高壓電暈放電和液相化學(xué)氧化煙氣脫硝具有明顯的協(xié)同效應(yīng)。脫硝機(jī)理主要包括氣相電暈放電等離子體氧化反應(yīng)和液相氧化吸收反應(yīng)。
[Abstract]:In order to understand the influencing factors and mechanism of synergistic denitrification between high voltage corona discharge and liquid phase chemical oxidation, the power supply voltage and water volume flow rate were studied under the synergistic action of high voltage corona discharge and liquid phase chemical oxidation. The effects of the kinds of absorbent, the initial mass concentration of no and the volume flow rate of flue gas on denitrification efficiency are discussed. The mechanism of synergistic denitrification between high pressure corona discharge and liquid phase chemical oxidation is discussed. No gas is mixed with air through Flowmeter to form simulated gas. No concentration was measured and flue gas denitrification efficiency was calculated. The results showed that denitrification efficiency increased with the increase of power supply voltage, water volume flow rate and absorbent concentration, but with the initial mass concentration of no. Under the synergistic effect of 3 kV high voltage corona discharge and 5% H_2O_2, The denitrification efficiency of flue gas is as high as 60.2. There is an obvious synergistic effect between high-pressure corona discharge and liquid-phase chemical oxidation flue gas denitrification. The mechanism of denitrification mainly includes gas phase corona discharge plasma oxidation reaction and liquid phase oxidation absorption reaction.
