『壹』 什么叫过滤面积
在过滤分离中是指有过滤孔的面积。比如一块过滤板的过滤面积，如果是一面有过滤布，就算这个面积，如果两面都有过滤布，过滤板中间有排液通道，就要乘2了。
『贰』 如何计算有效过滤面积
有效过滤面积计算方法：
(1)、截面积S1计算：
S1=（0.2/2）2×3.14=0.0314 ㎡（过滤器进出口管道直径版DN200）。
(2）、过滤器有效过滤面积S2计算权：
S2/ S1=3，即S2= S1×3=0.0314×3=0.0942 ㎡（标准要求面积比取3）
(3)、过滤器过滤网面积计算按照项目要求，过滤网要求0.8mm，表面积0.45㎡。本过滤器选择蓝式滤芯的表面积为0.56 ㎡，滤篮支撑结构开孔率取50%，滤网选24目（可拦截0.785mm以上颗粒），其有效开孔率为56%。
有效过滤面积为S=0.56×0.5×0.56=0.157 ㎡，有效过滤面大于0.0942 ㎡， 因此在过滤面积上满足要求。

『伍』 什么是过滤面积
过滤面积是表征过滤机大小的参数。
以过滤介质阻力为主的过滤中，以颗粒床层的面专积为过滤属面积（板框过滤机的纱布面积）；滤饼过滤中的滤饼面积。
这是化工原理中的定义方式，应该也适用于化学学科吧，希望对你有帮助，呵呵！
『陆』 如何计算过滤面积
滤筒有效过滤面积计算公式：
A=L×2×N×M
A-过滤面积m2
L-滤材褶皱宽度回m
N-滤材褶皱数量（个）
M-滤筒高度m
滤答筒过滤面积是指滤筒上滤材展开的有效面积。当我们把滤筒垂直布置时，滤筒越高对节约整体成本越有利。但滤筒过高，清灰会较困难，目前国际上一般最长的滤筒也是2米。如果除尘器进口粉尘浓度越高，滤材折叠数可选少一点，折宽选浅一点，即过滤面积少一点，这样更有利于清灰。对于滤筒式除尘器过滤风速一般为0.6～1.8m/min。最理想的过滤风速为0.9m/min。当粉尘浓度较高时，可以考虑选择较低的过滤风速，降低了过滤风速有利于提高除尘器的过滤效率，延长滤筒使用寿命，降低工作阻力，改善通风性能。但除尘器造价有所提高，但在有些特殊情况下，滤筒除尘器的过滤风速也可选到3m/min以上。
