基于低低温电除尘器的烟气协同治理方法
摘要：
本发明涉及基于低低温电除尘器的烟气协同治理方法，解决了现有技术中烟气处理系统烟气处理效果差的不足。本发明提供的基于低低温电除尘器的烟气协同治理方法，在低低温电除尘器前接入热回收器，热回收器将烟气温度降低到85摄氏度至95摄氏度之间，该温度区间远低于酸露点，从而大大优化了低低温电除尘器的除尘效果；湿法脱硫装置串接于低低温电除尘器后方，提高了湿法脱硫装置的协同除尘效果，经过本方法处理后的烟气，烟尘排放可达到5mg/m3以下；SO2排放≤35mg/m3；NOX排放≤50mg/m3；SO3的脱除率可达95％以上。
摘要（英）：

The invention relates to a smoke collaborative treatment method based on an ultra-low temperature electric deduster. By the adoption of the smoke collaborative treatment method, the defect that in the prior art, the smoke treatment effect of a smoke treatment system is poor is overcome. According to the smoke collaborative treatment method based on the ultra-low temperature electric deduster, a heat recovery device is connected to the portion in front of the ultra-low temperature electric deduster, the smoke temperature is decreased to 85-95 DEG C through the heat recovery device, and the temperature range is much lower than the acid dew point, so that the dedusting effect of the ultra-low temperature electric deduster is greatly optimized; and a wet desulphurization device is connected to the portion behind the ultra-low temperature electric deduster in series, so that the collaborative dedusting effect of the wet desulphurization device is improved. According to the smoke treated through the smoke collaborative treatment method, the smoke dust emission can reach 5 mg/m<3> or less, the SO2 emission is smaller than or equal to 35mg/m<3>, the NOX emission is smaller than or equal to 50 mg/m<3> and the removal rate of SO3 can reach 95% or over.
