电荷对粉尘和病原体团聚影响的数学模型研究

由于封闭畜禽舍内聚集了大量的粉尘和病原体,将影响到动物和饲养人员的呼吸道健康,因此迫切需要研究去除粉尘和病原体的方法。以粉尘和病原体的结合体为研究对象,利用蒙特卡罗法及相关概率模型,研究电荷对粉尘和病原体团聚影响。通过研究粉尘和电荷间的附着模型,确定其附着受粒子半径、电荷情况、风速等因素影响;之后,进一步构建粉尘、病原体间以及病原体、电荷间的附着模型。结合数值化运算设定边界条件,得出三者间的结合率可达到15%。粉尘、病原体与电荷相互之间模型的建立能有效的了解到畜禽舍除尘的方法,提高除尘效率,并为高压静电除尘的推广和应用提供了理论基础。

Study on the Mathematical Model of Effect of Charge on Dust and Virus Aggregation inLivestock Houses

A large amount of dust and pathogens are accumulated in the enclosed livestock and poultry houses,which will be a threat to the respiratory health of animals and farmers.Therefore,it is urgent to study the methods of removing dust and pathogens.In this paper,the effect of electric charge on dust and pathogen agglomeration was studied using Monte Carlo method and related probability model.First of all,it was determined that the attachment was affected by particle radius,charge,wind speed and other factors by studying the adhesion model between dust and charge.After that,the attachment model of dust-pathogen,pathogen-pathogen and pathogen-charge were con-structed.In this paper,the boundary condition was set via numerical operation,and the binding rate of them was up to 15%.The establishment of the model between dust,pathogen and electric charge can make the dust removal meth-ods effective and apprehensible in livestock and poultry houses,which provides a theoretical basis for the populariza-tion and application of high voltage electrostatic dust removal.
