Method for harmlessly treating hazardous waste desulfurizer through European smelting furnace

TIAN GUO / ZOU QINGFENG / LIU PENGNAN

The invention discloses a method for harmlessly treating a hazardous waste desulfurizer through an European smelting furnace, sulfur in the hazardous waste desulfurizer is reduced into elemental sulfur by using the reduction atmosphere of an European smelting furnace system, fixed slagging of sulfur and economic treatment of slag as a building material are realized through chemical reaction in the furnace, the production process is stable, and the treatment amount of the waste desulfurizer is large; secondary pollutant emission is eliminated, and obvious environmental protection benefits are achieved; the European smelting furnace co-processing waste desulfurizer breaks through the traditional process limit value of utilizing a cement rotary kiln to co-process solid waste/hazardous waste, achieves the target of large-scale co-processing waste desulfurizer on a metallurgical furnace, namely the European smelting furnace, and develops a new way of solid waste/hazardous waste treatment. The technology which is low in cost, harmless in reducing atmosphere, free of secondary pollution of dioxin, high in treatment capacity and capable of treating solid waste/hazardous waste in a high-valued mode is achieved, and the blank at home and abroad is filled.

本发明公开了一种欧冶炉无害化处理危废脱硫剂的方法，利用欧冶炉系统还原氛围将危废脱硫剂中的硫进行还原成为单质硫，经过炉内化学反应，实现硫的固定渣化，炉渣作为建筑材料经济化处理，本发明生产工艺稳定,废脱硫剂处理量大；消除了二次污染物排放，具备明显的环保效益；欧冶炉协同处置废脱硫剂突破了传统利用水泥回转窑协同处理固废/危废的工艺限值，在冶金炉窑——欧冶炉上实现了规模化协同处理废脱硫剂的目标，开发了固废/危废处理的新途径，实现了低成本、还原氛围无害化不产生二噁英的二次污染、处理能力大，高值化处理固废/危废的技术，填补了国内外空白。
