焦炭滤料简介
焦炭滤料是高温干馏的固体产物，主要成分是碳，是具有裂纹和不规则的孔孢结构体(或孔孢多孔体)。裂纹的多少直接影响到焦炭的力度和抗碎强度，其指标一般以裂纹度(指单位体积焦炭内的裂纹长度的多少)来衡量。衡量孔孢结构的指标主要用气孔率(指焦炭气孔体积占总体积的百分数)来表示，它影响到焦炭的反应性和强度。
焦炭滤料强度通常用抗碎强度和耐磨强度两个指标来表示。焦炭的抗碎强度是指焦炭能抵抗受外来冲击力而不沿结构的裂纹或缺陷处破碎的能力，用M40值表示；焦炭的耐磨强度是指焦炭能抵抗外来摩檫力而不产生表面玻璃形成碎屑或粉末的能力，用M10值表示。焦炭的裂纹度影响其抗碎强度M40值，焦炭的孔孢结构影响耐磨强度M10值。M40和M10值的测定方法很多，我国多采用德国米贡转鼓试验的方法。
焦炭滤料特点
焦炭滤料由于其机械强度高，多孔隙率，吸附性能好，截污能力强，去除水中悬浮固体，净水水质，具有很好的效果，广泛用于生活用水和工业水处理装置中。不同用途的焦炭，对气孔率指标要求不同，一般冶金焦气孔率要求在40～45%，铸造焦要求在35～40%，出口焦要求在30%左右。焦炭裂纹度与气孔率的高低，与炼焦所用煤种有直接关系，如以气煤为主炼得的焦炭，裂纹多，气孔率高，强度低；而以焦煤作为基础煤炼得的焦炭裂纹少、气孔率低、强度高。
焦炭滤料的粒径
1、用于生活饮用水的焦炭滤料的粒径范围为：0.8-1.2mm、1.2-2mm；工业用水焦炭滤料的粒径范围为：1-2mm、2-4mm、4-6mm。
2、在各种粒径范围的焦炭中，小于指定下限粒径的不应大于3%，大于指定上限粒径的不应大于2%。
焦炭滤料的技术要求
1、焦炭滤料的破碎率和磨损率之和不应大于3%（百分率按质量计，下同）。
2、焦炭滤料的平均密度一般不小于1.4g/cm3，不大于1.6g/cm3。
3、焦炭滤料应不含可见泥土、页岩和外来碎屑。焦炭含泥量不应大于3%，密度大于1.8g/cm3的物质含量不应大于8%。
4、焦炭滤料的盐酸可溶率不应大于3.5%。
焦炭滤料理化指标
检测项目 | 测试指标 | 检测项目 | 测试指标 |
固定碳 | >80% | 盐酸可溶率 | ≤3.5% |
水分 | <5% | 磨损率 | ≤1.4% |
灰分 | <10% | 破碎率 | ≤1.6% |
填充密度 | 0.89 g/cm | 空隙率 | 47-53% |
含泥量 | <4% | 强度 | 95% |
焦炭滤料用途
主要用于高炉炼铁和用于铜、铅、锌、钛、锑、汞等有色金属的鼓风炉冶炼，起还原剂、发热剂和料柱骨架作用。还用于铸造、化工、电石和铁合金，其质量要求有所不同。如铸造用焦，一般要求粒度大、气孔率低、固定碳高和硫分低；化工气化用焦，对强度要求不严，但要求反应性好，灰熔点较高；电石生产用焦要求尽量提高固定碳含量。

Coke filter materials
Coke filter material is high temperature carbonization of solid product, main component is carbon, is a spore structure crack and irregular hole hole (or spore porous body).Crack much directly affect the strength of coke and crushing strength, its index with crack degrees commonly (coke within the crack length per unit volume) to measure.Measure the main hole spore structure with porosity (coke pore volume percentage of the total volume), it affects the reactivity of coke and strength.
The intensity of coke filter material is typically used crushing strength and abrasion resistance strength represented two indicators.Coke crushing strength refers to the coke can resist by external impact and not along the structure crack or defect broken ability, expressed in M40 value;The wear-resisting of coke strength refers to the coke can resist external friction without the ability to produce glass formation on the surface of particles or powder, said with M10 values.The crack degree of coke affect its crushing strength M40 value, coke M10 hole spore structure impact abrasion strength value.M40 and determination method of M10 value a lot of, our country many meters in Germany gong drum test method.
Coke filter material characteristics
Coke filter materials because of its high mechanical strength, porosity, adsorption performance is good, sewage capability is strong, removal of suspended solids in water, water purification, water quality has the very good effect, is widely used in domestic water and industrial water treatment plant.Different USES of the coke, different requirements to porosity index, general metallurgical coke porosity requirements in 40 ~ 45%, coke demand in 35 ~ 40%, and export coke demand at around 30%.Coke crack and porosity of high and low, have direct relations with the coal used in coking, such as coke is given priority to with development of refined, cracks, porosity, high intensity is low;And based on coking coal as a refined coal coke crack less, low porosity, high strength.
Coke filter material particle size
1, used for drinking coke particle size range of filter material are as follows: 0.8-1.2 mm, 1.2 2 mm;Industrial water coke filter material particle size range is: 1-2 mm, 2 -- 4 mm, 4 -- 6 mm.
2, in various sizes of coke, less than a specified minimum size should not be greater than 3%, is greater than the specified maximum particle size should not be greater than 2%.
Coke filter materials technical requirements
1, coke filter material crushing rate and the wear rate should not be greater than the sum of 3% (percentage in accordance with the quality, the same below).
The average density of 2, coke filter is generally not less than 1.4 g/cm3, not more than 1.6 g/cm3.
3, coke filter material should be clay, shale, and does not contain visible foreign debris.Coke silt content should not be greater than 3%, more than 1.8 g/cm3 density matter content should not be greater than 8%.
4, coke filter material of hydrochloric acid soluble rate should not be greater than 3.5%.
Coke filter materials use
Mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.Also used in casting, chemical industry, calcium carbide and ferroalloy, its quality requirement is different.If foundry coke, general demand big granularity, low porosity, high fixed carbon and sulfur content is low;Chemical gasification with coke, lax to strength requirement, but it requires good reactivity, high ash melting point;Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.
