基于塔式扩散模型的火电厂污染物监测方法研究

环境污染问题日益严重,雾霾天气不断威胁人类的健康,需要对污染物排放进行实时监测。为了更加准确地预测火电厂烟气污染物的排放,实时在电子地图上显示污染物浓度,提出了一种基于塔式扩散模型的火电厂污染物排放监测显示方法。对传统的污染物扩散模型进行优化处理,在此基础上提出了一种新型的塔式扩散模型来计算污染物浓度,利用不同高度扩散系数不同分层计算不同的污染物浓度。经大量实验证明,塔式扩散模型提高了烟气污染物排放监测的安全性、准确性和高效性。...

Environmental pollution is becoming increasingly serious, the fog and haze continues to threaten human health, so real-time monitoring of pollutant emissions is needed. In order to more accurately predict the thermal power plant flue gas pollutant emissions and real-time display pollutant concentration on electronic map, this paper proposes a pollutant discharge monitoring display method for thermal power plant based on tower diffusion model. It optimizes the traditional pollutants diffusion model, and on the basis, puts forward a kind of new tower diffusion model to calculate the pollutant concentration, with which different pollutant concentrations are calculated hierarchically by using that the diffusion coefficient are at different heights. A large number of experiments prove that the proposed tower model improves the safety, accuracy and efficiency of the monitoring of flue gas pollutant emissions.
