压缩空气饱和含水量与压力成反比,即工作压力越低,吸干机的湿度负荷越大,因此要求的再生气量也大。
压缩空气饱和含水量与压力成反比,即工作压力越低,吸干机的湿度负荷越大,因此要求的再生气量也大。
Compressed air saturated water content is inversely proportional to the pressure, that is, the lower the working pressure, the greater the humidity load of the dryer, so the required regeneration gas is also large.
干燥机的结构我们知道,再生空气是由孔板或球阀的开启度和两侧的压力差决定的。在流通面积一定的情况下,流经孔板或球阀的再生气量与压力成正比,工作压力的下降会导致再生气量的减小从而使吸干机再生效率降低,影响吸附效率。
From the structure of the dryer, we know that the regeneration air is determined by the opening degree of the orifice or ball valve and the pressure difference on both sides. In the circulation area, flows through the orifice valve or the regeneration air flow is proportional to pressure, working pressure decrease will lead to reduced regeneration gas so that the dryer regeneration efficiency decreased, affecting the adsorption efficiency.
压缩空气的体积与压力成反比,较低的工作压力使压缩空气空塔流速提高,吸附剂与压缩空气的接触时间缩短,导致动态吸附容量的下降。
The volume of compressed air is inversely proportional to the pressure, and the working pressure of the compressed air increases the velocity of the compressed air, and the contact time between the adsorbent and the compressed air is shortened, which leads to the decrease of the dynamic adsorption capacity.
由于压力下降、空塔流速提高,导致吸附床层的压力损失加大。 因此工作压力降低必然引起产品气出口露点上升、再生气量加大、压力降上升。
The pressure loss of the adsorbent bed is increased due to the decrease of the pressure and the increase of the air velocity. Therefore, the decrease of working pressure will inevitably lead to the increase of the dew point of the gas outlet, the increase of the regeneration gas and the increase of the pressure drop.
