Zeolite wheel adsorption concentration and activated carbon adsorption concentration have become two mainstream treatment processes in the VOC organic waste gas treatment market. However, the efficiency of activated carbon adsorption and purification has rapidly decreased, making it prone to ignition. The zeolite runner has gradually been accepted by domestic owners.

我们发现，在沸石转轮的技术交流中，业主废气的相对湿度通常会被调查，因为沸石转轮公司在选择沸石转轮时通常需要客户提供废气的相对湿度。由于相对湿度超过80%，沸石转轮的净化效率将大大降低。因此，如果废气的相对湿度超过80%RH，则需要增加湿度调节单元。

We found that in the technical exchange of zeolite wheels, the relative humidity of the owner's exhaust gas is usually investigated, because zeolite wheel companies usually require customers to provide the relative humidity of the exhaust gas when selecting zeolite wheels. Due to relative humidity exceeding 80%, the purification efficiency of the zeolite runner will be greatly reduced. Therefore, if the relative humidity of the exhaust gas exceeds 80% RH, it is necessary to add a humidity regulating unit.

那么，活性炭对废气的相对湿度有要求吗有，而且相对湿度要求低于沸石转轮，活性炭对废气的相对湿度要求为60%。目前，活性炭吸附脱附设备中几乎没有湿度调节单元。

So, does activated carbon have a requirement for the relative humidity of exhaust gas, and the requirement for relative humidity is lower than that of zeolite wheels. Activated carbon requires a relative humidity of 60% for exhaust gas. At present, there are almost no humidity adjustment units in activated carbon adsorption and desorption equipment.

常用的沸石分子筛是由Si/O和Al/O四面体结构单元组成的合成不溶性铝硅酸盐。其中，硅原子或铝原子构成四面体的中心。所有硅氧四面体和铝氧四面体通过共享顶点的氧原子连接成多个环，多个环相互连接形成立体骨架。这种铝硅酸盐中的硅氧比为1:2，符合简单的SiO2。由于网格框架中的Al3+离子取代了Si4+离子，网格框架具有负电荷。为了平衡Al/O四面体的负电荷，网格框架间隙中需要有补偿电荷的阳离子。

The commonly used zeolite molecular sieve is a synthetic insoluble aluminosilicate composed of Si/O and Al/O tetrahedral structural units. Among them, silicon or aluminum atoms form the center of the tetrahedron. All silicon oxygen tetrahedra and aluminum oxygen tetrahedra are connected into multiple rings through oxygen atoms sharing vertices, and the multiple rings are interconnected to form a three-dimensional skeleton. The silicon to oxygen ratio in this aluminum silicate is 1:2, which conforms to the simple SiO2. Due to the substitution of Si4+ions by Al3+ions in the grid framework, the grid framework has negative charges. In order to balance the negative charge of Al/O tetrahedra, cations with compensating charges are needed in the gap of the grid frame.

这些阳离子成为极性点，使沸石分子筛具有亲水性。合成沸石转轮的吸湿能力强于硅胶，每升空气中的水分可低于10-4mg。因此，为了提高沸石分子筛的疏水性，有必要消除极性离子，即降低结晶中的铝含量，使沸石转骨架中没有硅和氧原子。硅和氧原子之间的键距为1.6，离子半径为0.40和1.40，因此吸附微孔被氧原子包围。Si-O-Si键中的氧原子既不碱性也不形成氢键。因此，微孔表面无极，疏水。

These cations become polar points, making the zeolite molecular sieve hydrophilic. The moisture absorption capacity of synthetic zeolite wheels is stronger than that of silica gel, and the moisture content in each liter of air can be less than 10-4mg. Therefore, in order to improve the hydrophobicity of zeolite molecular sieves, it is necessary to eliminate polar ions, that is, reduce the aluminum content in the crystallization, so that there are no silicon and oxygen atoms in the zeolite skeleton. The bond distance between silicon and oxygen atoms is 1.6, and the ion radii are 0.40 and 1.40, so the adsorption micropores are surrounded by oxygen atoms. The oxygen atoms in the Si O-Si bond are neither alkaline nor form hydrogen bonds. Therefore, the surface of micropores is polar and hydrophobic.
