烟尘采样器在铜冶炼工艺烟气监测中的应用

摘要

The process flue gas of copper smelting are in high temperature, high concentrations of sulfur dioxide. In the past, constant current method has been used in monitoring electric dust collector, which has low automation level, low data accuracy and high failure rate. Based on improved flue gas preprocessor and absorbing liquid, and used the microcomputer dust sampler in copper smelting process flue gas monitoring, the flue gas parameters can satisfy the requirements of the instrument, data accuracy has improved significantlyafter preprocessing. The application successfully solves the problem of constant current sampling.%铜冶炼工艺烟气温度高,二氧化硫浓度高,其电收尘的监测以往一直采用恒流法,恒流法存在自动化水平低、数据准确性低、故障率高等问题.通过改进烟气预处理器和吸收液,并将微电脑烟尘采样器应用于铜冶炼工艺烟气监测,经预处理后烟气各参数均满足仪器要求,数据结果准确性明显提高.通过此应用成功解决了恒流法采样的问题.
