一种氧化锌联合脱硫脱硝系统及方法
摘要：
本发明公开了一种氧化锌联合脱硫脱硝系统及方法，该氧化锌联合脱硫脱硝系统包括脱硫脱硝吸收系统、氧化锌浆液制备系统、氢氧化钠溶液制备系统和氧化锌脱硫浆液过滤系统，采用氧化锌浆液和氢氧化钠溶液联合脱除冶炼烟气中的SO2和NOX，脱硫脱硝效率高。脱硫塔下部为氧化锌浆液喷淋段，上部为氢氧化钠喷淋段，两个喷淋段喷淋及循环独立运行，在提高脱硫脱硝效率的同时，降低了设备的投资成本。另外，本发明布局合理，操作方便，运行可靠，工艺流程易控制，具有很好的使用价值和应用前景。
摘要（英）：

The invention discloses a system and method for zinc oxide combined desulfurization and denitration. The system for zinc oxide combined desulfurization and denitration includes a desulfurization and denitration absorption system, a zinc oxide slurry preparation system, a sodium hydroxide solution preparation system and a zinc oxide desulfurization slurry filtering system, zinc oxide slurry and a sodium hydroxide solution are combined to remove SO2 and NOX in metallurgical off-gas, and the efficiency of desulfurization and denitration is high. The lower part of a desulfurization tower is a zincoxide slurry spraying section, the upper part is a sodium hydroxide spraying section, and spraying and circulation of the two spraying sections are performed independently, so that the efficiency ofdesulfurization and denitration is improved, and meanwhile the investment cost of the devices is reduced; in addition, the system has reasonable layout, convenient operation, reliable operation, an easily controlled technological process and a good application value and application prospect.
