摘要
在利用发酵罐制备沼气中,其产气量与温度有较大关系,保证发酵罐内物料处于适宜的发酵温度是确保原料中的微生物形成稳定种群的重要因素,且有利于提高产气量,通过利用ANSYS软件对发酵罐的温度场进行分析可得到罐底、罐顶及整体罐体的温度沿罐壁截面温度的分布情况,得到罐体和罐顶是整个发酵罐热量损失的主要部分,而罐底由于有保温措施,热量损失相对较少,将此分析结果与理论计算相比较并结合,可以更好的指导实际应用.
The gas production has a great relationship with temperature in Biogas fermentation process. An optimum temperature is the necessary factor to ensure that the raw material in the fermentation tank microbes can form stable dominant population and to improve gas production. Through analyze the temperature field of fermentation tank used ANSYS can get the temperature of bottom,roof and the whole tank along the cross section temperature distribution of tank wall,obtain the roof diffusion rate is the largest,second is the whole tank,and the tank bottom is the minimum.If just consider the perspective of heat,the heat dissipating capacity from high to low in turn is the whole tank,roof and the tank bottom.,It is a better guide that the analytical results compared with the theoretical calculation and combination in practical application.
