一种用化纤废渣泥制备磷酸锌联产氯化钠的方法
摘要：
本发明属于化工三废治理和利用的技术领域，尤其是一种用化纤废渣泥制备磷酸锌联产氯化钠的方法；其主要技术方案为：将化纤废渣泥洗涤后调成稀乳液与盐酸进行反应，反应生成的气体经过吸收后再利用；反应生成的混合液体依次加入少许氯化钙和氢氧化锌，进行反应后过滤，然后将滤液与磷酸钠进行反应，生产磷酸锌和氯化钠的混合溶液，过滤后滤饼进行洗涤、干燥、粉碎后检斤包装得到磷酸锌粉体产品，氯化钠溶液经蒸馏冷却结晶、粉碎包装后成为氯化钠晶体产品；本发明不但有效的治理了化纤生产行业所产生的废泥，消除化工污染，而且能将化纤废渣泥改造成为具有经济价值的磷酸锌和氯化钠产品，生产工艺及其设备简单，成本低廉。
摘要（英）：

The invention belongs to the technical field of chemical industry three-waste treatment and utilization, and in particular relates to a method for simultaneously preparing zinc phosphate and sodium chloride by chemical fiber waste residue mud. The main technical scheme comprises washing chemical fiber waste residue mud, preparing into diluted emulsion, reacting with hydrochloric acid, and recycling the gas generated during reaction through absorption; adding a small amount of calcium chloride and zinc hydroxide sequentially in the mixed liquid generated after reaction, and filtering after reaction; then carrying out reaction on filtrate and sodium phosphate to produce the mixed solution of zinc phosphate and sodium chloride, and filtering; washing filter cake, drying, crushing, checking weight, and packaging to obtain zinc phosphate powder product; and distilling the sodium chloride solution, cooling and crystallizing, crushing and packaging to obtain the sodium chloride crystal product. According to the method provided by the invention, not only is waste mud generated by the chemical fiber production industry treated effectively, the chemical industry pollution is eliminated, but also the chemical fiber waste mud can be changed into zinc phosphate and sodium chloride products with economic value, the production process and the device thereof are simple, and the cost is low.
