研制了一种碱性水玻璃（lNa 2o·msio2·nh2o）泡沫水玻璃（FWG），并将其应用于垃圾焚烧炉烟道的除HCl和二恶英抑制剂中。事实证明，用FWG焚烧聚氯乙烯（聚氯乙烯）可以大大减少聚氯乙烯的HCl排放，表明FWG是一种有用的HCl去除剂。通过注入稀释的FWG溶液作为冷却水，工业废物焚烧炉烟道中的HCl浓度也比传统的氢氧化钙颗粒降低的效率更高。HCl生成的减少导致烟气和飞灰中二恶英浓度的降低。
We developed a foaming water glass (FWG), a kind of alkaline sodium silicate hydrate (lNa 2 O·mSiO 2 ·nH 2 O) and applied it to a HCl remover and a dioxin inhibitor in flue of waste incinerators. HCl emissions from PVC (polyvinyl chloride) proved to decrease substantially by incinerating the PVC with the FWG, indicating that the FWG is a useful HCl remover. HCl concentrations in flues of industrial waste incinerators were also reduced with larger efficiency than the conventional calcium hydroxide particles by injecting a diluted FWG solution as a cooling water. The reduction of HCl generation led to the decrease in dioxin concentrations in flue gas and fly ash.
