1、操作条件通常情况下、低温操作有利于物理吸附，适当升高温度有利于化学吸附。但采取升温还是降温，必须以吸附过程中吸附烙变为依据。若烙变为正值，则温度升高对吸附操作有利;相反则降低温度对吸附过程有利。温度对气相吸附的影响比对液相吸附的影响大。对于气体吸附，压力增加有利于吸附，压力降低有利于解吸。

1. Under normal operating conditions, low temperature operation is conducive to physical adsorption, and appropriately increasing the temperature is conducive to chemical adsorption. However, whether to raise or lower the temperature must be based on the change of adsorption during the adsorption process. If the soldering becomes positive, the increase of temperature is beneficial to the adsorption operation; On the contrary, reducing the temperature is beneficial to the adsorption process. The effect of temperature on gas phase adsorption is greater than that on liquid phase adsorption. For gas adsorption, the increase of pressure is conducive to adsorption, and the decrease of pressure is conducive to desorption.

2、吸附剂的性质，吸附剂的性质如孔隙率、孔径、粒度等，影响比表面积，从而影响吸附效果。一般说来，吸附剂粒径越小或微孔越发达，其比表面积越大，吸附容量也越大。但在液相吸附过程中，对相对分子质量大的吸附质，微孔提供的表面积不起很大作用。

2. The properties of adsorbent, such as porosity, pore size and particle size, affect the specific surface area and thus the adsorption effect. Generally speaking, the smaller the particle size of adsorbent or the more developed the micropores, the larger the specific surface area and the larger the adsorption capacity. However, in the process of liquid phase adsorption, the surface area provided by micropores does not play a great role in the adsorbate with large relative molecular weight.

3、吸附质的性质与浓度对于气相吸附，吸附质的当量直径、相对分子质量、沸点、饱和性等影响吸附量。若用同种活性炭作吸附剂，对于结构相似的有机物，相对分子质量和不饱和性越大，沸点越高，越易被吸附。对于液相吸附，吸附质的分子极性、相对分子质量、在溶剂中的溶解度等影响吸附量。相对分子质量越大，分子极性越强，溶解度越小，越易被吸附。吸附质浓度越高，吸附量越少。

3. The properties and concentration of adsorbate affect the gas phase adsorption, and the equivalent diameter, relative molecular weight, boiling point and saturation of adsorbate affect the adsorption capacity. If the same activated carbon is used as adsorbent, the higher the relative molecular weight and unsaturation, the higher the boiling point and the easier it is to be adsorbed. For liquid phase adsorption, the molecular polarity, relative molecular weight and solubility in solvent of adsorbate affect the adsorption capacity. The greater the relative molecular weight, the stronger the molecular polarity, the smaller the solubility, and the easier it is to be adsorbed. The higher the concentration of adsorbate, the less the adsorption capacity.

4、吸附剂的活性吸附剂的活性是吸附剂吸附能力的标志，常以吸附剂上所吸附的吸附质量与所有吸附剂量之比的百分数来表示。其物理意义是单位吸附剂所能吸附的吸附质量。

4. Activity of adsorbent the activity of adsorbent is a sign of the adsorption capacity of adsorbent, which is often expressed as the percentage of the ratio of the adsorption quality adsorbed on the adsorbent to all adsorption doses. Its physical meaning is the adsorption mass that can be adsorbed by unit adsorbent.

5、接触时间吸附操作时，应保证吸附质与吸附剂有一定的接触时间，使吸附接近平衡，充分利用吸附剂的吸附能力。吸附平衡所需的时间取决于吸附速率，一般要通过经济权衡，确定好接触时间。

5. Contact time during adsorption operation, it shall be ensured that the adsorbate has a certain contact time with the adsorbent to make the adsorption close to equilibrium and make full use of the adsorption capacity of the adsorbent. The time required for adsorption equilibrium depends on the adsorption rate. Generally, the contact time should be determined through economic trade-off.

脉冲除尘器的吸附器的性能对吸附效果有较显著的影响，应合理设计吸附器的结构、吸附层的铺设等，以保证吸附器发挥优良的吸附性能。

The performance of the adsorber of the pulse dust collector has a significant impact on the adsorption effect. The structure of the adsorber and the laying of the adsorption layer should be reasonably designed to ensure the excellent adsorption performance of the adsorber.
