Description

一种空气干砂选煤系统Air dry sand coal preparation system 技术领域Technical field
本发明涉及煤炭分选技术领域,具体是指一种空气干砂选煤系统。The invention relates to the technical field of coal separation, in particular to an air dry sand coal preparation system.
背景技术Background technique
中国是产煤大国,随着煤炭工业的飞速发展及采煤机械化水平的不断提高,原煤的质量不断下降,同时煤炭用户为了提高经济效益和满足环保的需要,从而对煤炭产品的质量不断提出更高要求,未经分选的原煤不能使用,因此选煤已成为煤炭生产和利用过程中必不可少的重要环节。原煤分选的实质是利用煤炭与其他矿物质的物理化学性质的差异,用机械的方法除去原煤中的杂质,如矸石.硫铁矿等,将原煤分成不同质量规格的精煤产品。China is a major coal-producing country. With the rapid development of the coal industry and the continuous improvement of the coal mining mechanization level, the quality of raw coal continues to decline. At the same time, in order to improve economic efficiency and meet the needs of environmental protection, coal users continue to propose more High requirements, unsorted raw coal can not be used, so coal preparation has become an indispensable important link in the process of coal production and utilization. The essence of raw coal sorting is to use the difference in physical and chemical properties of coal and other minerals to mechanically remove impurities in raw coal, such as gangue, pyrite, etc., to separate raw coal into refined coal products of different quality specifications.
随着选煤工业发展,原煤的分选工艺可分为两种:水选和干法选,这两种工艺都存在极大的问题弊端。With the development of coal preparation industry, the separation process of raw coal can be divided into two types: water separation and dry separation, both of which have great problems and disadvantages.
水选:上个世纪以前,纵观全世界所有的选煤方法都离不开水——选煤全是在水溶液中进行的,利用煤和矸石的颗粒大小不同及密度的差异,在溶液中进行分选,用的最广泛的方法是跳汰选、重介质选和浮选。因传统的选煤方法必须在水溶液中进行分选,导致如下问题:Water Separation: Before the last century, all coal preparation methods in the world were inseparable from water-coal preparation is all carried out in aqueous solution, using the difference in particle size and density of coal and gangue in solution For sorting, the most widely used methods are jig sorting, heavy medium sorting and flotation. Because the traditional coal preparation method must be sorted in aqueous solution, it leads to the following problems:
1.选煤必须用水且耗水,处理1吨原煤平均耗水量0.2m 3,最多时要用到3吨水,但矿区的地质结构及地理位置注定了水源的贫乏,地球上即便是非产煤区亦有1/5以上的地区严重缺水,自然水源不能满足选煤使用,要么人工调水,要么将原煤运往水源充足处异地集中分选,成本高且操作不便。 1. Coal preparation must use water and consume water. The average water consumption for processing 1 ton of raw coal is 0.2m 3. At most, 3 tons of water are used. However, the geological structure and geographical location of the mining area are destined to be deficient in water sources. Even if the coal is not produced on the earth There are also more than one-fifth of the districts where there is a serious shortage of water. The natural water source cannot meet the needs of coal preparation. Either manually adjust the water, or transport the raw coal to a place where there is sufficient water source for centralized separation. The cost is high and the operation is inconvenient.
2.煤泥污水外流不但造成煤炭损失,也严重地污染了环境,导致土壤板结等问题,为减少大量外排煤泥污水,必须实现洗水闭路循环,为实现洗水闭路 循环必须对污水进行净化处理,为此必须附设专用污水净化系统设备,成本高且降低了选煤效率。2. The outflow of slime sewage not only causes coal loss, but also seriously pollutes the environment, causing soil compaction and other problems. In order to reduce a large amount of external slime sewage, the closed circuit of washing water must be realized. To achieve the closed circuit of washing water, sewage must be carried out. For purification treatment, special sewage purification system equipment must be attached for this purpose, which is costly and reduces the efficiency of coal preparation.
3.煤炭中的水分严重影响甚至决定着产品的质量指标,亦同时增加无效运输,在高寒地区湿煤冬运还会发生冻车涨车现象,为降低选后产品的水分含量,必须附设专用的脱水机械进行脱水,但脱水只是相对的而不是绝对的,就目前的脱水技术,经脱水处理后的产品仍含有一定的水分,不利于煤块的直接利用。3. The moisture in the coal seriously affects and even determines the quality index of the product, and at the same time increases the invalid transportation. In the cold and cold regions, the wet coal winter transportation will also cause the frozen car to rise. In order to reduce the moisture content of the selected product, a special Dehydration machinery performs dehydration, but dehydration is only relative rather than absolute. With current dehydration technology, the product after dehydration still contains a certain amount of water, which is not conducive to the direct utilization of coal.
4.分选不彻底,煤中有矸,矸中有煤,跳汰选煤中因煤和矸石在分选过程中没有明确的界面,分离时不彻底,综合分选效果不超过80%,分选质量较低,我国的重介选煤技术始于1958年,该选煤流程较为复杂,设备、管道容易磨损,维修养护工作量大,在操作、调节方面的要求更为严格,重介质悬浮液选煤的分选效果较好,但介耗较大仍是困扰我国重介选煤的一个主要问题,在选煤生产实践中,介耗在1.5kg/t左右就属于相当好的水平,一般选煤厂介耗在3kg/t左右,略高一点是5~6kg/t,有的选煤厂则达到了10kg/t甚至更高。4. The separation is not complete, there is gangue in the coal, and there is coal in the gangue, because there is no clear interface between the coal and gangue in the jigging coal separation process, the separation is not complete, and the comprehensive separation effect does not exceed 80%. The separation quality is low. China's heavy-medium coal preparation technology began in 1958. The coal preparation process is more complicated, equipment and pipelines are easy to wear, and the maintenance and maintenance workload is large. The requirements on operation and adjustment are more strict. The separation effect of suspension coal preparation is better, but the large medium consumption is still a major problem that plagues China's heavy medium coal preparation. In the coal preparation production practice, the medium consumption is about 1.5kg / t, which is a very good level In general, the media consumption of coal preparation plants is around 3kg / t, slightly higher is 5-6kg / t, and some coal preparation plants have reached 10kg / t or even higher.
5.选煤工艺繁杂,需附设大量的辅助机械设备,从而导致投建或改造选煤厂投资巨大,动辄就是几千万元,甚至几亿元。5. The coal preparation process is complicated, and a large amount of auxiliary mechanical equipment is required, which leads to huge investment in the construction or transformation of the coal preparation plant, which is often tens of millions of yuan, or even hundreds of millions of yuan.
干法选:Dry method selection:
第一阶段即奠基阶段:1984年,中国矿业大学在全球范围内率先研究干法选煤,完成了实验室基础研究、模型试验研究,建立了“空气重介质稳态流化”的选矿理论,于1987年5月28日,在中国知识产权局申报“干式流化床选煤装置”申请号:8710105,此后,中国矿业大学即着手实施该项目,进行工业化试验,在太原的白家庄煤矿建立了世界上第一座试验基地,但该装置存在如下问题:The first stage is the foundation laying stage: In 1984, China University of Mining and Technology was the first in the world to study dry coal preparation, completed laboratory basic research, model test research, and established the "air heavy medium steady-state fluidization" mineral processing theory. On May 28, 1987, the application number of "Dry Fluidized Bed Coal Preparation Device" was filed with the China Intellectual Property Office: 8710105. Since then, China University of Mining and Technology has begun to implement the project and carry out industrialization trials in Baijiazhuang, Taiyuan. The coal mine established the world's first test base, but the device has the following problems:
1.排矸方式是利用刮板强力推刮,导致核心部件频繁被矸石、煤泥等杂物 堵塞、损坏而不能正常工作,后几经改进,采用其它方案,仍然不能满足正常的使用要求。1. The gangue discharge method is to use the scraper to push the scraper forcefully, which causes the core components to be frequently blocked and damaged by debris such as gangue, coal slime, etc., and cannot work normally. After several improvements, the use of other schemes still cannot meet the normal use requirements.
2.使用的介质是颗粒状的铁沙,损耗太大,每年损耗几百吨,一方面增加成本浪费资源,另一方面这些铁沙混在煤炭中燃烧时高温炽热容易损坏锅炉。2. The medium used is granular iron sand, which consumes too much, and consumes hundreds of tons per year. On the one hand, it increases costs and wastes resources. On the other hand, when these iron sands are burned in coal, the high temperature and heat are easy to damage the boiler.
3.整体的成本造价过高且生产效率低,无法实现工业应用。3. The overall cost is too high and the production efficiency is low, which cannot be used in industrial applications.
第二阶段即探索阶段:国内现有复合式干法选煤技术也称风选,其基本原理是通过床面的摇摆或振动,使原煤在小颗粒煤粉的托付下,依赖于外来风力作用实现轻重分向流动。此技术存在如下弊端:The second stage is the exploration stage: the existing domestic composite dry coal preparation technology is also called air separation. Its basic principle is to make the raw coal under the trust of small particles of coal powder rely on external wind force through the swing or vibration of the bed surface. Achieve light and heavy flow. This technology has the following disadvantages:
1.分选效果差:此种方式仅属于“劣煤淘汰盘”早在1956年中国就开发了摇床分选,此技术只是在摇床分选时增加风力,对摇床分选稍作改进而已,因煤和矸石在分选过程中没有明确的界面,床面越振越实,变成死床,分离时不彻底,综合分选效果不超过75%。1. Poor sorting effect: This method only belongs to the "inferior coal elimination plate". As early as 1956, China developed the shaker sorting. This technology only increased the wind power during the shaker sorting, and made a little difference to the shaker sorting. Only improvement, because the coal and gangue do not have a clear interface in the separation process, the more vibrating and solid the bed surface becomes a dead bed, the separation is not complete, and the comprehensive separation effect does not exceed 75%.
2.分选效率低。2. The sorting efficiency is low.
3.结构复杂体积庞大,导致制作成本大,占地面积大,处理量100吨/小时的体积超过1000立方米,导致新建和改造选煤厂的投资巨大,动辄就是几百万甚至几千万元。3. The complex structure and huge volume lead to large production cost, large area, and a processing capacity of 100 tons / hour with a volume of more than 1000 cubic meters, resulting in huge investment in the construction and renovation of coal preparation plants, which is often millions or even tens of millions. yuan.
4.能耗大,处理量100吨/小时的系统功率需300千瓦。4. Large energy consumption, the system power of 100 tons per hour needs 300 kilowatts.
5.生产成本高,维修费用大。5. High production cost and large maintenance cost.
6.粉尘较多,污染环境。6. There is much dust, which pollutes the environment.
第三阶段即现状:国内有科技工作者于2008年将此前中国矿业大学的方案略作改进:用密布小孔及风帽的聚乙烯塑料板取代原金属布风板,存在如下问题:The third stage is the status quo: domestic science and technology workers slightly improved the previous scheme of China University of Mining and Technology in 2008: replacing the original metal cloth wind plate with a polyethylene plastic plate with densely covered small holes and a wind cap, the following problems exist:
1.块状及粒状的矸石仍直接落在聚乙烯塑料板表面,因仍采用刮板强力推 刮,会很快堵塞和磨损,导致无法正常工作。1. Blocky and granular gangue still falls directly on the surface of the polyethylene plastic board. Because the scraper is still used to force the scraper, it will quickly block and wear, resulting in failure to work properly.
2.制造工艺复杂,制造成本过高,结构繁杂,以及耗电量巨大,导致选煤成本较高,接近于水选。2. The manufacturing process is complicated, the manufacturing cost is too high, the structure is complicated, and the power consumption is huge, which results in a high cost of coal preparation, which is close to that of water separation.
以上各因素导致至今干法选煤仍不能实现工业应用。The above factors have caused the industrial application of dry coal preparation so far.
综上所述,因为现有干法选煤技术仍存在很多不成熟的问题,尚不完善,仅处于探索尝试阶段,所以不能推广应用,目前还是以水选为主。In summary, because the existing dry coal preparation technology still has many immature problems, it is still not perfect, and it is only in the exploration and trial stage, so it cannot be promoted and applied. At present, water separation is still the main method.
本发明人经进一步改进完善,又开发出全套无水选煤系统---空气干砂选煤系统,以彻底解决传统选煤的诸多弊端。After further improvement and perfection, the inventor has developed a complete set of water-free coal preparation system --- air dry sand coal preparation system to completely solve many disadvantages of traditional coal preparation.
