Description

A kind of air dry sand Recognition Applied in Coal Preparation System
Technical field
The utility model relates to coal separation technical field, in particular to a kind of air dry sand Recognition Applied in Coal Preparation System.
Background technique
China is big coal country, with the rapid development of coal industry and the continuous improvement of mining mechanization level, raw coal Quality constantly decline, while coal consumers in order to increase economic efficiency and meet environmental protection needs, thus to coal product Quality constantly proposes requirements at the higher level, and not sorted raw coal cannot use, therefore coal separation has become coal production and utilizes process In essential important link.The essence of raw coal separation is the difference using the physicochemical properties of coal and other minerals It is different, the impurity in raw coal, such as spoil troilite are removed with machinery method, and raw coal is divided into the cleaned coal of different quality specification Product.
As coal preparation industry develops, the sorting process of raw coal can be divided into two kinds: wet concentration and dry method choosing, both techniques are all deposited In very big problem drawback.
Wet concentration: before eighties of last century, make a general survey of all coal preparation methods in the whole world all be unable to do without water --- coal separation is in water entirely It carries out in solution, using coal and the granular size difference of spoil and the difference of density, is sorted in the solution, it is most wide General method is jigging, dense media choosing and flotation.Because traditional coal preparation method must be sorted in aqueous solution, cause as Lower problem:
1. coal separation must use water and water consumption, 1 ton of raw coal average water consumption 0.2m is handled3, 3 tons of water are used when most, but The poor of water source has been doomed in the geologic structure in mining area and geographical location, even if on the earth being the ground that the non-coal-producing area also has 1/5 or more Area's serious water shortage, natural water source, which is not able to satisfy coal separation use or artificial water transfer or transports to have abundant water resources by raw coal, locates strange land Sorting is concentrated, it is at high cost and inconvenient.
2. the outflow of coal slime sewage not only causes Coal Loss, it also seriously polluted environment, lead to soil hardening, To reduce a large amount of outlet coal slime sewage, it is necessary to closed water circuit is realized, to realize that closed water circuit must carry out sewage Purified treatment, must set up dedicated sewage purification system equipment thus, at high cost and reduce coal separation efficiency.
3. the moisture in coal seriously affects or even decide the quality index of product, also increase ineffective traffic simultaneously, The wet coal winter transportation of extremely frigid zones also occurs that freezing vehicle rises vehicle phenomenon, for the moisture content for reducing product after choosing, it is necessary to set up dedicated Dewatering machine is dehydrated, but dehydration is only opposite rather than absolute, just current dehydration technique, after dehydration Product still contains certain moisture, is unfavorable for the direct utilization of coal cinder.
4. sorting is not thorough, there is cash in coal, there is coal in cash, because coal and spoil be not bright in assorting room in coal jigging True interface, when separation, are not thorough, and comprehensive dressing effect is no more than 80%, and sorting quality is lower, the dense-medium separation technology in China It starts from 1958, the coal separation process is complex, and equipment, pipeline are prone to wear, and maintains heavy workload, in operation, adjusts The requirement of aspect is more stringent, and the separating effect of heavy-media suspension coal separation is preferable, but it is still puzzlement China's dense medium that the consumption that is situated between is larger One main problem of coal separation, in coal separation production practices, the consumption that is situated between just belongs to fairly good level in 1.5kg/t or so, generally Medium consumption in preparation plant is in 3kg/t or so, and more slightly higher is 5~6kg/t, and it is even higher that some coal preparation plants have then reached 10kg/t.
5. coal preparation technique is many and diverse, a large amount of accessory machinery need to be set up, so as to cause investing to build or being transformed coal preparation plant's investment It is huge, it is easily exactly several ten million yuan or even several hundred million yuan.
Dry method choosing:
First stage, that is, Foundation stage: 1984, China Mining University took the lead in studying dry coal preparation in the world, complete At laboratory basic research, model investigation, the ore dressing for establishing " air dense medium stable state fluidisation " was theoretical, in 1987 " coal-selecting device in dry fluidized " application number was declared in China Intellectual Property Office May 28: 8710105, hereafter, Chinese Mining Industry University sets about implementing the project, carries out industrial test, and the Bai Jiazhuan coal mine in Taiyuan establishes First test in the world Base, but there are the following problems for the device:
1. discharge refuse mode is pushed using scraper plate strength, cause core component frequently by the blocking of the sundries such as spoil, coal slime, damage Badly cisco unity malfunction, it is rear several improved, using other schemes, it is not still able to satisfy normal requirement.
2. the medium used is that granular iron is husky, loss is too big, and several hundred tons are lost every year, on the one hand increases cost waste Resource, high temperature is red-hot when on the other hand these iron sand are mixed in burning in coal is easily damaged boiler.
3. whole cost is excessively high and production efficiency is low, industrial application cannot achieve.
Second stage, that is, exploratory stage: domestic existing combined type dry coal separation technology is also referred to as selection by winnowing, the basic principle is that logical Cross waving or vibrating for bed surface, make raw coal under the entrusting of little particle coal dust, dependent on the effect of external wind-force realize weight point to Flowing.This technology exists as following drawbacks:
1. separating effect is poor: such mode only belongs to " smut buddle " and just develops shaking table point early in China in 1956 Choosing, this technology only in separation by shaking table increases wind-force, slightly modified to separation by shaking table, because coal and spoil are in assorting room In without specific interface, bed surface the more shakes the more real, becomes dead bed, and when separation is not thorough, and comprehensive dressing effect is no more than 75%.
2. the efficiency of separation is low.
3. it is bulky that structure is complicated, cause cost of manufacture big, take up a large area, the volume that 100 ton/hours for the treatment of capacity is super 1000 cubic metres are crossed, causes investment newly-built and that coal preparation plant is transformed huge, is easily exactly millions of or even several ten million yuan.
4. energy consumption is high, the system power that 100 ton/hours for the treatment of capacity needs 300 kilowatts.
5. high production cost, maintenance cost is big.
6. dust is more, environment is polluted.
Phase III, that is, status: the country has scientific worker slightly to change in the scheme by China Mining University before this in 2008 Into: replace virgin metal air distribution plate with the polyethylene panel of gather aperture and blast cap, there are the following problems:
1. blocky and granular spoil still directly falls in vinyon plate surface, carries on as before and pushed using scraper plate strength, meeting Blockage and wear quickly lead to not work normally.
2. manufacturing process is complicated, manufacturing cost is excessively high, and structure is many and diverse and power consumption is huge, leads to coal separation higher cost, Close to wet concentration.
Above each factor cause so far dry coal preparation still can not achieve industrial application.
In conclusion because of existing dry coal preparation technology, there are still many jejune problems, not perfect, only exist in spy The rope trial stage, so cannot promote and apply, at present or based on wet concentration.
The utility model people is further improved perfect, and develops a full set of anhydrous Recognition Applied in Coal Preparation System --- air dry sand coal separation System, thoroughly to solve many drawbacks of traditional coal separation.
