<p class="MsoNormal">
<span style="font-family:SimSun;font-size:18px;">填料性能的优劣通常根据效率、通量及压降三要素衡量。在相同的操作条件下,填料的比表面积越大,气液分布越均匀,表面的润湿性能越好,则传质效率越高;填料的空隙率越大,结构越开敞,则通量越大,压降亦越低。采用模糊数学方法对九种常用填料的性能进行了评价,得出如表</span><span style="font-family:SimSun;font-size:18px;">3-1</span><span style="font-family:SimSun;font-size:18px;">所示的结论。可看出,丝网波纹填料综合,拉西环最差。表</span><span style="font-family:SimSun;font-size:18px;">3-19</span><span style="font-family:SimSun;font-size:18px;">种填料综合性能评价填料名称</span> <span style="font-family:SimSun;font-size:18px;">评估值</span> <span style="font-family:SimSun;font-size:18px;">语言值排序丝网波纹填料</span><span style="font-family:SimSun;font-size:18px;">0.86 </span><span style="font-family:SimSun;font-size:18px;">很好孔板波纹填料</span><span style="font-family:SimSun;font-size:18px;">0.61</span>

</p>
<p class="MsoNormal">
<span style="font-family:SimSun;font-size:18px;">在泛点气速下,持液量的增多使液相由分散相变为连续相,而气相则由连续相变为分散相,此时气体呈气泡形式通过液层,气流出现脉动,液体被大量带出塔顶,塔的操作极不稳定,甚至会被破坏,此种情况称为淹塔或液泛。影响液泛的因素很多,如填料的特性、流体的物性及操作的液气比等。</span>
</p>
<p class="MsoNormal">
<span style="font-family:SimSun;font-size:18px;">填料特性的影响集中体现在填料因子。填料因子</span><span style="font-family:SimSun;font-size:18px;">F</span><span style="font-family:SimSun;font-size:18px;">值越小,越不易发生液泛现象。</span>
</p>
<p class="MsoNormal">
<span style="font-family:SimSun;font-size:18px;">流体物性的影响体现在气体密度</span><span style="font-family:SimSun;font-size:18px;">rV</span><span style="font-family:SimSun;font-size:18px;">、液体的密度</span><span style="font-family:SimSun;font-size:18px;">rL</span><span style="font-family:SimSun;font-size:18px;">和粘度<鲍尔环生产厂家/span><span style="font-family:SimSun;font-size:18px;">mL</span><span style="font-family:SimSun;font-size:18px;">。气体密度越小,液体的密度越大、粘度越小,则泛点气速越大。</span>
</p>
<p class="MsoNormal">
<span style="font-family:SimSun;font-size:18px;">操作的液气比愈大,则在一定气速下液体喷淋量愈大,填料层的持液量增加而空隙率减小,故泛点气速愈小。</span>
