摘　　要：针对含有毒有害细颗粒物的特种烟尘排放控制,设计了一套三段式低温等离子体处置系统,该系统包括流光氧化、双极性凝并和静电收集3段。以粉煤灰样品作为替代物进行荷电和收集实验,结果表明,细颗粒物在经过双极性荷电发生凝并后,又经三电场静电除尘,烟尘排放出口浓度最低可达0.076 mg/m^(3),颗粒物收集效率达到99%。利用L-苯丙氨酸甲酯盐酸盐在缩比反应器中进行流光等离子体氧化实验,处理后,结果表明,—CH、—C=0、芳环和—NH等官能团大部分被破坏。该系统在化工、制药等行业具有良好的推广应用前景,可用于一些含有毒有害细颗粒物特种烟尘的排放控制。A three-stage low-temperature plasma treatment system is designed for the control of emission of special soot containing toxic and harmful fine particles.This system includes a streamer plasma oxidation section,a bipolar discharge coagulation section and an electrostatic collection section.The charging and collection experiments are carried out with fly ash samples as substitutes.Results show that the minimum concentration of fine particles at the outlet of dust emission can reach 0.076 mg·mand the collection efficiency of particles can reach 99%after the coagulation of fine particles by bipolar charging and the electrostatic precipitation by three electric fields.The streamer plasma oxidation experiment of L-phenylalanine methyl ester hydrochloride is carried out in a scale-up reactor.Treatment results show that most of the functional groups such as—C=0,aromatic ring and—NH are destroyed after treatment.This system can be used in chemical industry,pharmaceutical industry and other industries to control the emission of some special soot containing toxic and harmful fine particles.
