 Jingdezhen buys columnar activated carbon manufacturers

Columnar activated carbon purchase 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, Columnar activated carbon 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.

Zeolite molecular sieve is a kind of excellent adsorbent, which 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. The factors affecting the purification efficiency of honeycomb zeolite molecular sieves are absorption and desorption. 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, Columnar activated carbon purchase The service life of zeolite will be directly affected over time.

The zeolite wheel adsorption purification device is a gas purification device that can continuously perform adsorption and desorption operations. Columnar activated carbon purchase 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, purchase Jingdezhen 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

High silica zeolite type molecular sieves, this kind of zeolite has a series, and ZSM-5 is widely used, with ZSM-8 and ZSM-11 having the same structure; The other group is ZSM-21, ZSM-35 and ZSM-38. ZSM-5 is often called high silica zeolite, with the Si/Al ratio up to 50 and ZSM-8 up to 100. This group of molecular sieves also shows hydrophobic characteristics. Columnar activated carbon manufactor Their structural units are similar to those of mordenite, consisting of pairs of five membered rings, with no cage like cavities and only channels. ZSM-5 has two sets of cross channels, one is straight through, the other is zigzag perpendicular to each other, both formed by ten yuan rings. The channel is oval and its window diameter is (0.55-0.60) nm. Columnar activated carbon purchase Zeolites belonging to the high silicon group also have silicalite-1 of all silicon type, which has the same structure as ZSM-5, and silicalite-2 is the same as ZSM-11.

Columnar activated carbon Jingdezhen Since the adsorption does not change chemically, Columnar activated carbon purchase 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

Columnar activated carbon Jingdezhen 】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, Columnar activated carbon purchase 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.
