Product Name: Coke Filter Media for Sewage Treatment Type: Industrial Circulating Water Treatment Agent Appearance: Granulars Color: Black Environmental Protection: Yes Acid-base Property: Alkaline Surface Disposal Agent Specific Gravity: 0.86t/M3 Fixed Carbon: 85% Bulk Density: 0.85g/cm3 Ash: 12% Vm.: 1.5% Moisture: 7-10% Sample: Free Sulphur: 1% Transport Package: 25kg/Bag or 1tonbag Specification: 0.5-20mm Origin: China Product Description Coke Filter Media For Sewage TreatmentIntroduction of the coke:Bituminous coal in the isolated air conditions, heated to 950-1050 ºC, after drying, pyrolysis, melting, bonding, curing, contraction and other stages of the final production of coke, the process called high temperature coking (high temperature dry distillation). Coke obtained from high temperature coking is used for blast furnace smelting, casting and gasification. Coke produced in the process of recovery, purification of coke oven gas is both high calorific value of fuel, but also an important organic synthesis of industrial raw materials.Commonly size: 0.5-1, 1-2, 2-4, 4-6, 6-8, 8-16mmFeatures of the coke:Large adsorption capacity.Large specific surface area.Chemical stability.Long service cycle.Usage of the coke:Coke filterCoke filter because of its high mechanical strength, multi-porosity, good adsorption performance, sewage interception ability, coke filter to remove suspended solids in water, water purification, has a very good effect. Coke filter is widely used in chemical, steel, oil, printing and dyeing and other industrial water treatment coke filter.metallurgical cokeCoke is mainly used for blast furnace ironmaking and for the copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal blast furnace smelting, from the reducing agent, heaters and column skeleton role. Ironmaking blast furnace using coke instead of charcoal, laid the foundation for the modernization of modern blast furnace, metallurgical history is a major milestone. In order to achieve good technical and economic indicators for blast furnace operation, smelting coke (metallurgical coke) must have appropriate chemical and physical properties, including the thermal properties in the smelting process. Coke in addition to a large number of iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferroalloy, its quality requirements are different. Such as casting with coke, generally require large particle size, low porosity, fixed carbon and low sulfur content; chemical gasification with coke, the intensity is not strict, but requires good reactivity, ash melting point higher; calcium carbide production requirements Try to increase the fixed carbon content.Fuel grade cokeSpecification of the coke:Fixed carbon80-86%S1%Ash12%Moisture1.6%V.M.1.5%P0.003%Porosity 79.5%Hydrochloric acid dissolution rate0.86%Note:S of the coke: S is one of harmful impurity of the iron smelting. If the S content above 0.07%, the iron will be waste product.P of the coke: The P content should be bellow 0.02-0.03%, when you iron smelting.Ash of the coke: The ash add 1%, the coke need add 2-2.5%.Volatile matter of the coke: According to the content of the volatile matter we could adjust the grade of the maturity of the coke. Moisture of the coke: Moisture will make the M40 on the high side and make the M10 on the low side.Size: A. Coke powder: 0-1, 0-3mmB. Coke granular: 5-25mmC. Coke block: 25-80mm
