I.The introduction of shell activated carbon
Activated carbon, superheated steam catalysis and other craft refined, the appearance of the black unshaped particles, the series produced by the processing technology is made of the shell of the shells, Of an activated carbon. Husk activated carbon has the advantages of good wear resistance, developed voids, high adsorption capacity, high strength, easy regeneration, economic durability and so on.
II.The husk activated carbon parameters
Iodine adsorption value (mg / g): 600-1200
Specific surface area (㎡ / g): 800-1200
Ash (%): 6-8
Methylene blue (mg / g): 100-150
Strength (%): 95-97
PH value: 6-9
Filling density (g / m³): 0.38-0.45
Dry alkali content (%): ≤ 10%
III.The use of shell activated carbon
Shell activated carbon is widely used in drinking water, industrial water and wastewater deep purification life, industrial water purification and gas adsorption, such as power plants, petrochemicals, oil refineries, food and beverage, sugar, wine, medicine, electronics, fish, Industry water purification, can effectively adsorb the free chlorine, phenol, sulfur and other organic pollution, especially the mutagen (THM) precursors, to purify the impurity to smell. It can also be used for industrial exhaust gas purification, gas desulfurization, oil catalytic reforming, gas separation, pressure swing adsorption, air drying, food preservation, gas mask, solution carrier, industrial solvent filtration, decolorization and purification. Purifying and purifying various gases; organic solvent recovery; sugar, monosodium glutamate, medicine, alcohol, beverage decolorization, deodorization, refining; precious metal refining; chemical industry catalyst and catalyst carrier. Husk activated carbon more decolorization, purification, impurity, deodorant, to smell, carrier purification, recovery and other functions.
Application of Activated Carbon in Nutshell in Wastewater Treatment
1.Activated carbon treatment of waste water containing chromium;
2.Carbon treatment of cyanide-containing wastewater;
3.Activated carbon treatment of mercury - containing wastewater;
4.Activated carbon treatment of phenol wastewater;
5.Activated carbon treatment with methanol wastewater.
IV.The shell of activated carbon transport precautions
1.Husk activated carbon in the transport process, to prevent mixed with hard material, not step on, step, to prevent carbon particles broken, affecting the quality;
2.The storage should be stored in the porous adsorbent, so the transport storage and use of the process, we must absolutely prevent flooding, due to flooding, a large number of water filled with active space, it lost its role;
3.To prevent the use of tar substances in the process should be prohibited tar substances into the activated carbon bed, so as not to plug the gap of activated carbon, so that the loss of adsorption. Preferably with decoking equipment to purify the gas;
4.Fire-activated carbon in the storage or transport, to prevent direct contact with the fire source to prevent fire, activated carbon regeneration to avoid oxygen and regeneration completely, after regeneration must be cooled to 80 ℃ with steam cooling, or high temperature, Activated carbon spontaneous combustion.
