Activated carbon fiber Fuzhou Since the adsorption does not change chemically, Activated carbon fiber major As long as we try to drive away the molecules concentrated on the surface, zeolite molecular sieves will have adsorption capacity again. This process is the reverse process of adsorption, which is called the process of desorption or regeneration. Honeycomb zeolite molecular sieve is a kind of aluminosilicate material containing alkali metal or alkaline earth metal oxide with open framework and regular pore cage structure. It has been widely used since it was discovered by Swedish scientists in 1956, and then it has been widely used in petrochemical industry, environmental protection, bioengineering and other fields due to its special physical characteristics. And with the gradual expansion of the demand for zeolite molecular sieves, researchers began to expand a variety of synthetic methods of zeolite molecular sieves to meet the needs of various fields. Zeolite molecular sieve has super strong adsorption performance, which is due to a "surface force" generated by molecular gravity on the solid surface. When the fluid flows, some molecules in the fluid collide with the adsorbent surface due to irregular movement, resulting in molecular concentration on the surface, reducing the number of such molecules in the fluid to separation Purposes of clearing
Activated carbon fiber Fuzhou 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. Activated carbon fiber 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.

Activated carbon fiber major 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, Activated carbon fiber 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.
Activated carbon fiber major The operation is stable, and the exhaust gas concentration can reach the standard stably; High temperature desorption can be adopted, with high regeneration efficiency and high safety; Honeycomb zeolite is used as the adsorption carrier, with small resistance; Compact structure, small floor area of the whole equipment. Activated carbon fiber Fuzhou It has a wide range of applications and is suitable for treating various organic waste gases. Technical indicators of molecular sieve: the main material of honeycomb zeolite adsorbent is natural zeolite, and the zeolite manufacturer is mainly 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, 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.
