Sponge activated carbon major 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. Sponge activated carbon Beijing 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

Sponge activated carbon major The holes and channels inside the zeolite crystal are uniform and fixed in size, and the diameter of the holes is generally 6~15A. 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. Sponge activated carbon Beijing 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. 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.

High honeycomb zeolite molecular sieve content The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency, Sponge activated carbon major Therefore, when choosing to purchase zeolite runner, the matching zeolite content should be selected in combination with the emission concentration of enterprise exhaust gas pollutants. 2、 With good hydrophobicity, choose to purchase zeolite with large specific surface area. 2) Select inspection equipment to test the hydrophobicity of equipment Sponge activated carbon Direct selling 。 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.

Sponge activated carbon 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, Sponge activated carbon Direct selling 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.

Sponge activated carbon major The addition of retention aids in the wet end of paper making is an important way to improve filler retention, which has been widely used in industrial production. Some studies reported that clinoptilolite (particle size 0.5-2 μ m) was used as a microparticle retention aid to compare the retention effect with silica and bentonite microparticle retention aid systems. The retention effect of clinoptilolite retention aid is equivalent to that of the silica microparticle retention aid system with the same dosage, which is far better than that of the bentonite microparticle retention aid system. And the use of zeolite as paper filler eliminates the need for additional microparticle retention aids. It is also reported that the retention rate of TiO2 nanoparticles can be significantly improved by using zeolite molecular sieves as retention aids in the preparation of photocatalytic paper. Compared with starch and cationic polymer, zeolite molecular sieve microparticle retention aids have better effects on improving the retention and drainage properties of paper stock and improving the uniformity of paper. Sponge activated carbon major The use of zeolite particle retention aids can effectively avoid flocculation between fibers, and help to form fiber particle fiber flocculating particles. In addition, it can also support titanium dioxide nanoparticles.

Sponge activated carbon Beijing 】Zeolite adsorbent has outstanding advantages 1. Strong adsorption selectivity. The pore size of molecular sieve is uniform, and it is also an ionic adsorbent. Therefore, it can selectively adsorb according to the size and polarity of molecules. It can effectively remove ethylene, propylene and acetylene from saturated hydrocarbons, which is determined by its strong polarity. 2. Strong adsorption capacity. Even if the composition concentration of the gas is very low, it still has the adsorption capacity of. 3. It is less affected by temperature. At a higher temperature, it still has a greater adsorption capacity, while other adsorbents are greatly affected by temperature, so at the same temperature, the adsorption capacity of zeolite molecular sieve is large. 4. It can be regenerated at high temperature, with high regeneration efficiency and high safety. 5. Strong resistance to poisoning and good thermal stability. Zeolite molecular sieve is an excellent adsorbent, Sponge activated carbon major It is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases nox、co、co2，nh3，ccl4、 Purification of water vapor and gaseous hydrocarbon waste gas; As well as air purification and deodorization in biochemical industry, paint industry, underground places, leather factories and animal breeding places; Adsorption of flue gas odor, removal of mercury vapor, etc.
