Columnar activated carbon major 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 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, 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.

The zeolite wheel adsorption purification device is a gas purification device that can continuously perform adsorption and desorption operations. Columnar activated carbon major The two sides of the zeolite runner are divided into three areas by special sealing devices: adsorption area, desorption (regeneration) area and cooling area. The working process of the system is as follows: the zeolite runner rotates continuously at a low speed and circulates through the adsorption area, desorption (regeneration) area and cooling area; When the exhaust gas with low concentration and large air volume continuously passes through the adsorption area of the runner, VOCs in the exhaust gas are adsorbed by the zeolite of the runner, and the gas purified by adsorption is directly discharged; The organic solvent adsorbed by the wheel is sent to the desorption (regeneration) area along with the rotation of the wheel, and then continuously passes through the desorption area with small amount of hot air, major Henan VOCs adsorbed on the runner are thermally desorbed in the desorption area to achieve regeneration, and VOCs waste gas is discharged with hot air; After the runner is transferred to the cooling area for cooling, it can be re adsorbed. With the continuous rotation of the runner, adsorption, desorption and cooling cycles are carried out to ensure the continuous and stable operation of waste gas treatment

Columnar activated carbon Henan The adsorption and concentration technology of zeolite runner is highly praised by enterprises because of its high efficiency and energy saving. Its changeable working environment and low cost ensure the popularization and application of zeolite runner in industry. How to select a zeolite runner with stable operation and high efficiency? The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency. Therefore, when choosing to purchase the zeolite runner, the matching zeolite content should be selected in combination with the emission concentration of the enterprise's exhaust gas pollutants. Zeolites with large specific surface area shall be purchased for good hydrophobicity. Select the inspection equipment to test the hydrophobicity of the equipment. When the air humidity is greater than 60%, calibrate the equipment. If the equipment is blocked and the machine works abnormally, it indicates that the equipment has poor hydrophobicity, and you should carefully consider whether to purchase the equipment. The factors affecting the purification efficiency of zeolite due to high desorption efficiency are: absorption on the one hand and desorption function on the other. Columnar activated carbon major If the waste gas adsorbed on the runner cannot be completely desorbed, the runner will become saturated after a long time, which will affect the adsorption efficiency of the zeolite runner and directly affect the service life of the zeolite over time.

Molecular sieve has clear pore cavity distribution, extremely high internal surface area (600m2/s), good thermal stability (1000 ℃), and adjustable acid site center. The acidity of molecular sieve mainly comes from three coordinated aluminum atoms and aluminum ions (AlO)+on the framework and in the pores. OH based acid sensitive site center on molecular sieve HY obtained by ion exchange, Columnar activated carbon Henan The aluminum ions outside the framework will strengthen the acid site and form the L acid site center. Polyvalent cations such as Ca2+, Mg2+and La3+can show the acid site center after exchange. The reduction of transition metal ions such as Cu2+and Ag+can also form acid site centers. In general, the higher the Al/Si ratio, the higher the specific activity of OH group. The modification of zeolite acidity can introduce protons through direct exchange of dilute hydrochloric acid. This method often leads to dealumination of molecular sieve framework. So NaY will become NH4Y and then HY. Because there are uniform small internal pores in the molecular sieve structure, when the molecular linearity of reactants and products is close to the pore size of the crystal, the selectivity of the catalytic reaction often depends on the corresponding size of the molecule and pore size. Columnar activated carbon major This selectivity is called shape selective catalysis. There are two mechanisms leading to shape selectivity. One is caused by the difference of diffusion coefficient of molecules participating in the reaction in the pore cavity, which is called mass transfer selectivity; The other is caused by the space limitation of the transition state of the catalytic reaction, which is called transition state selectivity.

Honeycomb zeolite molecular sieve has the crystal structure and characteristics, the surface is a solid skeleton, and the internal holes can play the role of adsorption molecules. There are channels between the holes to connect with each other, and molecules pass through the channels. Due to the crystalline nature of the pores, the pore size distribution of the molecular sieve is very uniform. Molecular sieves selectively adsorb molecules according to the size of holes in their crystals, that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are vividly called "molecular sieves". The adsorption or repulsion function of molecular sieves is affected by the molecular electricity. Synthetic zeolite has the special function of selective adsorption according to molecular size and polarity, Columnar activated carbon production Therefore, gas or liquid can be dried or purified, which is also the basis for molecular sieve separation. Synthetic zeolite can meet the extensive demand of industry for adsorption and selective products, Henan Columnar activated carbon It is also widely used in industrial separation to synthesize zeolite molecular sieves.
