Small block activated carbon high quality Due to its large pore size, mesoporous materials have become a good carrier for molecular reaction with large size. However, the pore wall of mesoporous materials is amorphous, so their hydrothermal stability and thermal stability cannot meet the harsh conditions required for petrochemical applications. Because there are metal ions with low electricity price and large ion radius and water in the combined state, water molecules are continuously lost after heating, but the crystal skeleton structure remains unchanged, forming many cavities with the same size. The cavities are connected by many micropores with the same diameter. These tiny holes have uniform diameters, which can adsorb molecules smaller than the diameter of the hole into the interior of the hole, By excluding molecules larger than pores, molecules with different shapes, diameters, polarities, boiling points and saturation levels can be separated, Small block activated carbon manufactor It has the function of "screening" molecules, so it is called molecular sieve. At present, molecular sieves are widely used in metallurgy, chemical industry, electronics, petrochemical industry, natural gas and other industries.

Small block activated carbon high quality The highly effective selective adsorption is due to the fact that the alumina tetrahedron of zeolite has a negative charge, while the skeleton hole contains cations, which forms a strong electric field around the cations. Therefore, the adsorption force of zeolite not only has a strong dispersion force, but also has a large electrostatic force. It is precisely because of this electrostatic relationship that zeolites have preferential selective adsorption on polar, unsaturated and polarizable molecules. It can strongly adsorb molecules containing polar groups such as hydroxyl ion, ammonium ion and other polarizable groups, especially water, which can form hydrogen bonds with aluminum silicon skeleton, so zeolite has strong water absorption. It can still adsorb even under low relative humidity and concentration, and its water absorption is higher than that of silica gel and activated alumina. 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, Small block activated carbon manufactor Their polarity and molecular size are different, and competition will occur during adsorption.

Small block activated carbon high quality The high reliability makes users no longer worry about unexpected shutdown, which is the confidence brought by UOP molecular sieve. Traditional molecular sieves can be used as desiccants, adsorbents and ion exchangers. UOP also provides high silicon zeolite series molecular sieves for non-traditional applications, including molecular sieves to remove organisms that affect the taste of food and drinks or cause odor. Zeolite molecular sieves have 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 the size and polarity of molecules, so it can dry or purify gas or liquid, which is also the basis of molecular sieve for separation. Small block activated carbon Hunan Synthetic zeolite can meet the extensive demand of industry for adsorption and selective products, and is also widely used in industrial separation to synthesize zeolite molecular sieves. Advantages of UOP molecular sieve

Small block activated carbon high quality In the process of removing impurities in the liquid and gas phases, the porous structure of zeolite provides a large amount of specific surface area, which makes it very easy to absorb and collect impurities. Due to the mutual adsorption of molecules, a large number of molecules on the pore wall of zeolite can generate strong gravity, just like magnetic force, So as to achieve the purpose of attracting impurities in the medium to the aperture. 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, Small block activated carbon 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.

The zeolite runner device is essentially a concentrator. The waste gas containing organic solvent after treatment by the runner is divided into two parts: clean air that can be discharged directly and regeneration air containing high concentration organic solvent. Small block activated carbon Hunan 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. 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; Waste gas concentrated by runner, Small block activated carbon manufactor It 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.
