通过对传统氨法脱硫工艺进行改进,成功设计了一种零排放、生态友好、经济可行的环保型新型氨法脱硫工艺。该工艺的关键在于将脱硫工艺放置在脱硫塔与预脱硫塔之间,简化了脱硫工艺,提高了脱硫效率(91.5%)。同时副产品纳米粉体硫化锌粒径均匀,具有较高的纯度,经济价值优于目前传统氨法脱硫工艺所产生的副产品硫磺和硫膏。新工艺为煤焦化厂的绿色生产、安全生产和经济生产提供了新思路。

Through improving the traditional ammonia-route desulfurization process,a novel environmentally friendly ammonia-route desulfurization process with zero emission,ecological friendliness,economy and feasibility is successfully designed.The key of this process is to arrange the desulfurization process between the desulfurization tower and the pre-desulfurization tower,which simplifies the desulfurization process and improves the desulfurization efficiency (91.5%).Meanwhile,the by-product nano-powder zinc sulfide has uniform particle size and high purity,and its economic value is better than sulfur and sulfur paste by-products generated by the traditional ammonia desulfurization process.The novel process provides a new idea for green production,safe production and economic production of coal coking plant.
