【摘要】：泛点气速是填料塔设计的重要参数,Eckert关联图为目前工程上运用较为广泛的泛点气速求取方法。文中基于散堆填料的Eckert关联图,在考虑泛点填料因子鐖f随液体泛点喷淋密度Lf变化的条件下,提出了泛点气速uf的数值算法;推导出泛点气速uf的表达式为一个高度非线性化方程,并给出了该方程的2种求解方法。同时举例计算了一个散堆填料的泛点气速,并和著名的塔器流体力学计算软件(WPTR)计算结果做了对比。结果表明:文中的计算结果和WPTR的结果完全吻合;所使用的方程求解方法 Aitken-Steffensen具有快速、稳定的收敛性,可用于散堆填料的泛点气速计算。
[Abstract]:Pan-point gas velocity is an important parameter in packed tower design. Eckert correlation diagram is a widely used method for calculating pan-point gas velocity in engineering at present. Based on the Eckert correlation diagram of bulk packing, a numerical algorithm of pan-point gas velocity uf is proposed under the condition of considering the variation of pan-point packing factor f with liquid pan-point spray density Lf, and the expression of pan-point gas velocity uf is derived as a highly nonlinear equation, and two methods for solving the equation are given. At the same time, the pan-point gas velocity of a bulk packing is calculated by an example, and the results are compared with those of the famous tower hydrodynamic calculation software (WPTR). The results show that the calculated results are in good agreement with those of WPTR, and the equation solving method Aitken-Steffensen has fast and stable convergence, which can be used to calculate the pan-point gas velocity of bulk packing.
