The influences of temperature, air flow and the amount of copper chloride upon the types and amount of the toxic emissions such as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and polycyclic aromatic hydrocarbons (PAHs) during combustion of polyvinyl chloride (PVC) were investigated. The mechanism concerning the effect of temperature and copper chloride on the PCDD/Fs and PAHs formation was discussed. The results shown that without copper chloride, trace amounts of PCDD/Fs and large amounts of PAHs were found in the emissions from the pure PVC combustion under various combustion conditions. The addition of copper chloride enhanced PCDD/Fs formation, but it seems that the formation of PAHs decreased with increasing amount of copper chloride, and greater total amount of PAHs were produced at the higher temperature under our experimental conditions.
研究了温度、气流和氯化铜用量对聚氯乙烯(PVC)燃烧过程中多氯二苯并对二噁英和多氯二苯并呋喃(PCDD/Fs)以及多环芳烃(PAHs)等有毒排放物的种类和数量的影响。探讨了温度和氯化铜对PCDD/Fs和PAHs形成影响的机制。结果表明,在没有氯化铜的情况下,各种燃烧条件下纯PVC燃烧排放物中发现了痕量的PCDD/Fs和大量的PAHs。氯化铜的添加促进了PCDD/Fs的形成,但在我们的实验条件下,PAHs的形成似乎随着氯化铜用量的增加而减少,且在较高温度下产生的PAHs总量更大。
