The adsorption capacity of zeolite for organic pollutants mainly depends on the polar size and molecular diameter of organic molecules. Small molecules are easier to be adsorbed than large molecules, while polar molecules are easier to be adsorbed than non-polar ones. Different substances (such as organic molecules, metal ions and water molecules) exist in water, Honeycomb zeolite molecular sieve Yingtan Their polarity and molecular size are different, and competition will occur during adsorption. The main material of honeycomb zeolite adsorbent is natural zeolite. The manufacturer of zeolite is composed of silica Inorganic microporous material composed of al_2o_3 and alkaline metal or alkaline earth metal, with inner pore volume accounting for 40-50% of the total volume and specific surface area of 100-500 m2/g, is characterized by high temperature resistance, non flammability, good thermal stability and hydrothermal stability. It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and can be regenerated at high temperature. Compared with honeycomb activated carbon, its performance is about 25% of its efficiency, Honeycomb zeolite molecular sieve manufactor However, it is widely used in the fields of adsorption, separation, catalysis and environment due to its high temperature resistance and difficult ignition. It is more suitable for the treatment of organic waste gas with large air volume and low concentration.

Honeycomb zeolite molecular sieve high quality Technical performance and characteristics: simple structure, convenient maintenance and long service life; High absorption and desorption efficiency, so that VOCss waste gas with high air volume and low concentration can be converted into low air volume and high concentration waste gas, reducing the cost of back-end final treatment equipment; The pressure drop generated by the adsorption of VOCs by the zeolite runner is extremely low, which can greatly reduce the power consumption; The overall system adopts pre assembly and modular design, which has a small space requirement and provides a continuous and unmanned control mode; The waste gas concentrated by the runner can meet the national emission standards; The adsorbent uses non combustible hydrophobic zeolite, which is safer to use; The disadvantage is that the one-time investment is high. The zeolite runner is essentially a concentrator, Honeycomb zeolite molecular sieve manufactor The waste gas containing organic solvent after runner treatment is divided into two parts: clean air that can be discharged directly and regeneration air containing high concentration organic solvent. The clean air that can be directly discharged can enter the spray paint air conditioning ventilation system for recycling; The concentration of high concentration VOCs is about 10 times that of the VOCs before entering the system. The concentrated gas is then incinerated at high temperature through the TNV recovery thermal incineration system (or other equipment). The heat generated by incineration is respectively used to heat the drying room and the zeolite wheel desorption. The heat is fully used to achieve the effect of energy conservation and emission reduction.

Honeycomb zeolite molecular sieve Yingtan There are cavities and channels in the crystal structure of zeolite with large adsorption capacity, whose volume accounts for more than 50% of the total volume of zeolite crystals. Moreover, the micropores of zeolite are evenly distributed, and the pore size is small, which is equivalent to the molecular size of general substances. The internal surface area of zeolite crystals can reach more than 1000 square meters. Therefore, the adsorption capacity of zeolite is particularly large. The holes and channels inside the highly selective zeolite crystal are uniform and fixed in size, and the diameter of the holes is generally 6~15A. Honeycomb zeolite molecular sieve manufactor Only molecules with smaller diameter can enter the cavity through the zeolite channel and be adsorbed, while large molecules cannot enter the cavity and be adsorbed. Zeolite is also called molecular sieve because of its selective adsorption performance. However, silica gel, activated carbon and other adsorbents have no selective adsorption and screening performance due to their non uniformly fixed pore sizes and large changes.

Yingtan Honeycomb zeolite molecular sieve Zeolite is a porous aluminosilicate crystal (a1uminsi1ict) with a water bearing frame structure, which exists naturally in nature and is also artificially synthesized. The ideal chemical formula of zeolite can be expressed as Mx/yA1XSiyO2 (x y) P? H2O, Where, M is alkali metal (such as Na, K, Li) and alkaline earth metal (such as Ca, Mg, Ba, Sr). The chemical composition of zeolite is generally considered to be composed of A12O3, SiO2, H2O and metal cations, of which A12O3 and SiO2 account for about 80% of the total zeolite minerals. In different zeolite minerals, the proportion of silicon and aluminum is different, Honeycomb zeolite molecular sieve manufactor And the different proportion of zeolite will cause some changes in zeolite characteristics, such as ion exchange and acid resistance. Because the silicon (aluminum) oxygen tetrahedron of natural zeolite crystal has many holes and channels, which occupy cations and water molecules. When some other goods are completely dehydrated after baking, the crystal skeleton is not damaged, but forms large holes on the inner surface, which can absorb and store a large number of molecules, so it has the characteristics of large adsorption capacity and high selectivity.

Honeycomb zeolite molecular sieve high quality Rely on its own unique void structure. The pore size of zeolite is uniform, the internal void structure is developed, the specific surface area is large, the adsorption capacity is strong, and contains a large number of invisible pore sizes. The pore size in 1g zeolite material can be expanded to the specific surface area of 500-1000m2, which is higher for special purposes. The mutual adsorption between molecules is also called "van der Waals gravity". Although molecular motion speed is affected by temperature, material and other factors, Honeycomb zeolite molecular sieve manufactor But it always keeps moving in the micro environment. Due to the mutual attraction force between molecules, when a molecule is trapped in the inner pore volume of zeolite, it will lead to more molecules being absorbed until the adsorption of zeolite is saturated.
