<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;">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>
