化学吸收法处理含铅废气工艺的研究

Study on Chemical Absorption to Control Lead Dust

研究了利用稀醋酸吸收含铅废气中的铅,通过实验分析了空塔气速、液气比、气相浓度等对吸收效率的影响,并探讨了设计、制作安装斜孔板吸收塔应注意的问题。结果表明,采用稀醋酸作吸收剂的化学吸收法净化含铅粉尘及铅蒸气效果较好。

Using acetic acid to control lead dust is studied. The absorption effect and its affecting factor such as the gas flow rate in empty tower, the water gas ratio and the gas concentration are analyzed. The precautionary problems to design tower and installation tower are investigated. The result expatiates that the chemical absorption has good effect in absorption of load dust and gas.
