中文摘要:
      本文介绍了利用化学工业固体废弃物－电石渣和蒸氨碱渣，作为美国阿兰柯公司的荷电干式吸收剂喷射脱硫系统（CDSI）吸收剂的试验，以达到废治废的目的。实验室试验和工业试验结果均表明，这两种固体废弃物均可以作为脱硫吸收剂，对比试验结果表明，电石渣的脱硫能力优于蒸氨碱渣和商品Ca(OH)2。蒸氨碱渣与电石渣如以适当的比例混合后，脱硫能力与商品Ca(OH)2基本相同。
英文摘要:
      The Charged Dry-Sorbent Injection (CDSI) is an innovative technique for the desulfurization of flue gas, developed by the Alanco Environmental Resource Corp. in 1990s. In this technique, the sorbent particles are strongly charged with negative electrostatic charges and subsequently injected into the flue gas stream. The charged sorbent particles will repel each other and are hence rapidly dispersed throughout the gas stream. The uniform dispersion of the sorbent particles will increase the contact surface between the particles and the flue gas, and therefore increase greatly the reaction rate and the efficiency of SO2 removal. In this work, solid discards such as carbide slag and caustic-sludge from the chemical industry were considered to be utilized as substitutes for the conventional absorbents of CDSI systems, e.g. hydrated lime. Laboratory and industrial tests with carbide slag and caustic-sludge showed that they could be adopted as absorbents for the desulfurization process in the CDSI system. Furthermore, it was concluded from a comparative test that absorption using carbide slag as the absorbent in the CDSI system was more effective than using caustic-sludge and hydrated lime available on the market. If the two discards, i.e. carbide slag and caustic-sludge, were mixed in a certain proportion and used as the absorbent, the SO2 removal efficiency of the mixture was about the same as hydrated lime.
