The purposes of a little parts of appliance or green compact.The present invention relates more specifically to the device and method that green compact is produced from raw material, so far
Device and method be not possible to the basis of standard for coking, or device and method so far do not provide and make us full
The final products of meaning.In particular it relates to for providing unconventional raw material, set in particular for coking in vertical coke oven
Standby and method.In particular it relates to according to the device and method of the preamble of each independent claims.The present invention into
One step be related to especially with the related separate part of offer of the green compact (or briquetting) that is made of these alternative materials or equipment
Purposes.
Background technique
For national economy most of on our earth, coke and carbon raw material or carbon raw material are important substantially
Material represents valuable material in itself in the form of its is existing, and present circumstances is also so and in the future such.So far
Until the present, coking mainly is carried out to the bituminous coal (referred to as rich coal) with high agglomeration ability.However, certain form of coke can be short
Time internal world becomes rare in the market.Specifically must it is contemplated that be very suitable to the coking coal of coking availability will under
Drop, as a result, the coal or other carbon sources high using caking capacity difference or swellability may be needed, also in the future in particular for production
Blast-furnace coke.Due to various reasons, the political pressure especially on the territory including Europe, future will need to substitute
Product, especially for traditional bituminous coal, especially because in decades to come in, burning raw material may still extremely as the energy
It closes important.In Europe, since 2014, conventional coking coal has been considered as important raw material.But with other important raw materials
It compares, it is still endowed maximum economic significance.In conclusion herein it will be apparent that on the one hand there are contradictions, it is another
There are chances or motivation to be advantageously carried out further Optimized Measures since conventional coking process for aspect.
Currently, energy transition is only carried out in the rich countries of intense industrialization deeper into and developing country is according to very
For many years or the prior art decades ago will still rely on the traditional raw material of burning following many years.It is even big in such as Australia
Highly developed country as Leah currently has a large amount of investment activity more modern to be converted to especially in Queensland state
Coke oven technology and in the future continue can largely upgrade raw material at home.Therefore, for allowing to provide production
Or it can be used for the new machine of the certain form of coke of the raw material pedigree of coke production using coke or with restriction characteristic or extension
The device and method of meeting have great interest and high-tech demand.Certainly, it is also possible to avoid certain raw material through these means
The needs of long-distance transportation in the world.
One specific technological challenge is raw by the original coked material (including especially lignite) of weak agglomeration and non-agglomerated
Produce premium coke.In Europe, such raw material, which is more widely used, to be aroused people's interest, especially because with such as cigarette
The situation of coal is compared, and still can exploit such raw material under more acceptable cost scene.It is particularly related to the challenge,
The challenge is becoming more and more prominent recently, that is, so that can also utilize unconventional raw material.Especially make us feeling in this context
Interest is the purposes with the raw material of high sulfur content, especially because a variety of applications can become obviously, this allows just by institute
The sulphur obtained is used as by-product.
It has been proved that in many cases, only raw material or raw material being compressed in a specific way in advance and processing (example
Such as, by raw material briquetting/be pressed into coal briquette), coal could successful conversion be premium coke.Briquetting especially needs to bear in coke oven chambers
High pressure in bed, these height are several meters, and especially in large-scale vertical coke oven, briquetting should not be decomposed into small as far as possible
Grain.Therefore, the major criterion of advantageous technological design is also likely to be the accessible intensity of raw material, especially in vertical coke
In furnace for use.Therefore, when finding new alternative materials and new process, interested problem first is that form processing is asked
Topic, should ideally provide alternative materials, and how to carry out related processing in this form.
As described above, the coke oven for producing coke can use the form of so-called vertical coke oven.Vertical coke oven is from upper
Side is packed into raw material briquetting or coal briquette.The operation height of vertical coke oven may be very high, such as in the range of 30 to 40m.Example
Such as, briquetting is placed on above coke oven using crane, and passes through coking axis (coke oven chambers) sliding especially by gravity,
Especially pass through the time of a few hours, such as 12 or 15 hours, the time is corresponding to the time needed for converting the feedstock to coke.
In the process, briquetting can undergo temperature change, especially most from the initial temperature lower than 300 DEG C to 900 DEG C to 1100 DEG C
Finishing temperature.Coke oven generally includes the component of two to ten coke oven chambers, to form so-called furnace group.The axis of each coke oven chambers
Height especially can for 3.5 arrive 10m, width especially can be 150 to 600mm.It can be seen that in coking, briquetting
Bear high frictional force and pressure.Therefore, the intensity of briquetting is as high as possible.In addition, it is intended that becoming the volume in briquetting
Change and " effective " mass transfer is possibly realized.Therefore, certain porosity is also advantage.
In order to provide briquetting, raw material can be crushed in advance, especially crushed in hammer-mill, more particularly crushed
To 0 to 1mm granular size.Next, usually briquetting is compacted in press by compressed granulate, and so far,
In many cases, briquetting geometry is proved to be advantageous in a manner of the elongate pieces with optional fillet or rounded edges
's.The briquetting of ellipse produces well known to being also specifically by roll squeezer.
In order to increase agglomeration ability (particle cohesive force during and after compression) and/or improve the attached of the raw material crushed
Poly- performance can add water or steam.But once briquetting is by coking, high-moisture may generate not the intensity of briquetting
Benefit influence, as a result, especially in the lower region of vertical coke oven (maximum power or load effect are on briquetting) briquetting meeting
Avalanche simultaneously damages coking.
Actually it has been shown that in the whole process, will appear difficulty in different operating procedures, especially working as pressure
When the intensity of block is not high enough, the result is that coal/coke briquettes rupture in the bed of coking furnace.Therefore, in many cases, should observe
To > 30MPa numerical value as briquetting compression strength lower limit, especially in the case where big/high coke oven chambers.Therefore, when estimating
When counting the feasibility of raw material coking, enough compression strength can be considered as one of most important standard.Due to compression strength meeting
It is influenced by compressing or compressing, therefore the process has very high meaning.
Especially when the specified moisture content of raw material or briquetting can not be observed with enough accuracy, it may appear that further
Difficulty, as a result, during heating, briquetting bears high stress, specifically experience rupture or the disintegration of other forms.On
The observation in face show coke oven have efficient operation need as much as possible in the narrow margin of tolerance (especially in compression strength
In terms of water content) raw material or briquetting are provided.
From these considerations, it is apparent that when finding new method and apparatus, specifically it is noted that the following:
The definition of the specific heating curves of raw material in coke oven chambers;During coking and Raw material processing is specific at raw material during briquetting
The definition of technological parameter (especially temperature, duration, pressure), so that the type and volume of counterbalance stream, especially exist
In terms of the gas discharged in coking;Using and disposition option.
So far, system it is burnt the gas burner with vertical chamber or in the coking furnace with horizontal chamber into
Row.The latter can be divided into two types: (integrated) horizontal coke-oven, have narrow coke oven chambers, and upright indirect heating charges, and
So-called " hot (non-) recovery furnace " has the coke oven chambers of arch, lays flat charging in coke oven chambers, at least can also directly add from top
Heat.Current hypothesis is that both coking furnaces may be no longer able to sufficiently effective optimize to cope with following raw material
Utilizing for task.Seem develop a new concept for the coking furnace of a new generation, especially in face of using together with which
The demand of various different materials.Therefore, hereinafter, a kind of new concept is proposed, which grasps for providing for coking
The raw material of work, the raw material specifically can be adapted to using (coal) raw material usually used so far.
2012/0317878 A1 of publication US describe it is a kind of using granulation device and briquetting device for providing pressure
The method of block.Preferably there is drying unit between them.
Summary of the invention
In conjunction with the purpose then defined below for the present invention, it is advantageous that provide one kind or even unconventional raw material can be made
(the especially bituminous coal and/or biomass and/or petroleum coal of lignite and/or weak bonding) coking sets especially in vertical coke oven
Standby and method.It is advantageous that handling, providing and/or managing unconventional raw material in such a way, allow to the greatest extent may be used
Can by be used for so far conventional raw material (such as conventional bituminous coal briquetting) it is the same or similar in a manner of obtain after utilizing coking
The product obtained.
In this case, it is (especially burnt to be provided in particular in a kind of coke oven for iron at least one vertical coke oven chambers

200℃.It has been found that briquetting described herein may be advantageously used in this coke oven for iron.
Raw material specifically may include the entire pedigree of cherry coal, unglazed coal and glossiness lignite and flame coal.Specifically
Ground, the lignite that the Rhine, the river Lu Sasi and Indonesia produce have been carried out good result.It has also been found that described herein
Device and method be also suitable for lignite and flame coal and petroleum coal using Russia.Based on according to DIN, ASTM and UN-
The classification of ECE, raw material specifically may also include following coal type and mud coal, schematically replicate herein.Above and below of the invention
Wen Zhong, with reference to German DIN, have already appeared the coal for being particularly suitable for using include the soft brown coal classified in the DIN, it is matt brown
Coal, smooth surface lignite and flame coal。
Number in upper table is mass percent;About the number of volatile component, measured under the conditions of " waf ",
In other words, it is carried out in the state of anhydrous and ashless simultaneously.
The raw material of briquetting drier can be supplied to or briquetting includes or is made up of: specifically there is volatile component
The lignite and/or volatile component of >=45 mass percents and water content > 40 mass percents or > 45 mass percents 28 to
Weak caking coal within the scope of 45 mass percents or 12 to 22 mass percents.It is available especially high by this raw material
The enhancing briquetting of quality.
1.350 kilogram/cubic metre of density based on each briquetting, the bulk density of the indoor briquetting of coke oven can be
650kg/m3To 850kg/m3In the range of.
In this context, one kind is also specifically provided from least one solid material (especially from by lignite, weak bonding
Bituminous coal, biomass, petroleum coke and petroleum coal composition group in) production coke method, the raw material with briquette form provide simultaneously
And vertical coke oven chambers, especially coking furnace are provided to, especially above-mentioned coke oven for iron, wherein briquetting is first provided to pressure
Block drier, then it is carried out according to the forward speed of briquetting according to scheduled temperature curve it is continuous drying, especially by it
It dries at least two or three temperature levels (60 DEG C to 200 DEG C), and is subsequently supplied into coke oven chambers.This allows with very accurate
Can authorization predrying, pretreatment and slight processing are carried out to briquetting simultaneously.It has been found that briquetting described herein can be with
It is advantageously used in this method.
Raw material briquetting is passed through corresponding burnt with regular hour span (such as 4 to 15 hours, especially 6 to 9 hours)
Furnace chamber.In this procedure, raw material briquetting especially divide multiple stages from 100 DEG C to 200 DEG C (especially 150 DEG C) initial temperature
The final temperature being heated between 900 DEG C to 1100 DEG C.In such a case, it is possible to transverse to two of respective coke room
Required heat is generated in channel, these channels can be heated by multiple external burner, and heat can pass through stone material point
Next door indirect transfer is into corresponding coke oven chambers.
The type for constituting the coal of briquetting specifically includes (hard and soft) lignite, volatile coal ingredient (vc) >=45 mass hundred
Divide ratio, water content > quality 45%.The raw material for being processed into briquetting optionally include volatile component >=28 to 45 mass percents
Weak the gluing of (especially bottle coal, bluster coal and flame coal) or volatile component≤22 mass percents (especially forging and meager coal)
Tie bituminous coal.The caking property of weak caking coal itself is very low.Previous in hybrid manipulation, weak caking coal can be with adhesive
It mixes, therefore increases the adhesiving effect or agglomerated mass of coal particle in briquetting process.
Due to the property of its crucible coke, fatty coal specifically represents a kind of strong binding coal (traditional " coking coal ").
In addition, so-called forging coal and bottle coal are also calculated in strong binding coal.In the present specification, the coal of every other type is referred to as weak
Binding coal.
It has been found that briquetting can also be made of bituminous coal kind, such as anthracite (vc < 12%), meager coal (12% < vc <
19%), bottle coal (28% < vc < 35%), bluster coal (35% < vc < 45%) or the alternatively mixture of these coals, optionally
Also use higher aliphatic (coking) coal (19% < vc < 28%).By these percentages and based on the standard of type of coal, very
Extremely can more specifically it be distributed.
Raw material can be particularly ground into perforated plate roller mill especially with 0 to 2mm granularity pellet.
It has been found that being especially susceptible to bonding (they are easy agglomeration) by means of pellet/particle that perforated plate roller mill generates, therefore simplify
The briquetting process in downstream (compression).The invention purposes and design of perforated plate roller mill will be described in detail later.
After crushing, raw material are compressed.Compression operation (agglomeration) preferably carries out in formed channel press machine.
It was found that can realize especially pressure-resistant briquetting, the venturi in a manner of Venturi tube by means of the geometry of channel mould
Managing, there is cross section to shrink and flow out the shape that cross section broadens.Other kinds of press can not provide the result of nominal mass.
Furthermore, it has been found that can be obtained if squeezed after raw material is formed in a mold by tapered cross section
Obtain extra high briquetting intensity.When subsequent raw material passes through along the outflow section (runout section) to broaden, can obtain
Even higher briquetting intensity.The travel segment of contraction is advantageously shorter than outflow section, or the section than broadening with cross section is short.
It has been found that being in flattened cylindrical shape form (discoid, disk either before coking or after coking
Shape) briquetting all there is particularly preferred intensity value.Specifically, about heating and coking operation, briquetting diameter and briquetting height
Ratio (1 to 5, especially 2 to 3) also provide good result.The diameter of the briquetting is preferably 20mm to 100mm.Briquetting
Especially generated by 0 to the coal particle size (pellet) 2mm.
If it find that required intensity can also be realized by using different moulds or different types of press, then
Briquetting can also optionally have different geometries, for example, cube, bulk, sheet, mussel shape, cushion, spherical shape or ovum
Shape geometry.However, ice hockey shape has obtained optimum efficiency in experiment so far.
It is the parameter of this method below: moulding pressure, pressing time and pressed temperature.Compression specifically 120 to
It is carried out under the pressure of 150MPa, especially under the pressure of 140MPa.Compress the specifically temperature between 60 DEG C to 100 DEG C
Lower progress.The time of compression specifically up to 15 seconds.
It has been found that the kind of coal described herein can be mixed with coke promoters, to keep coking more efficient and assign
Coke product higher quality is given, such as higher intensity or higher reactivity.
According to one embodiment, at least one coke promoters is provided to briquetting process (in compression process), especially
In order to improve the efficiency of downstream coking.Coke promoters can select alone or in combination, especially selected from be proved so far with
The group for the coke promoters that conventional raw material is used in combination.
It has been found that passing through method described herein, when using lignite as raw material, the carbon content of generated coke
C (fixed value) can be improved to 55% or more, therefore, so that this coke is then even directly used in the direct melting of production steel also
Former process (the COREX/FINEX technique of PRIMETAL).
It is suppressing with before coking, in single phase or multistage hybrid manipulation, preferably (is gluing raw material and agglomeration
Close) and coke promoters mixing, it is suppressed especially for the quality for improving produced coke or the briquetting for promoting weak binding coal kind
Process.It is preferred that by this auxiliary agent before briquetting 30 DEG C to 120 DEG C at a temperature of mix.
Auxiliary agent specifically can be selected from the group being made of the following terms: molasses, sulfite solution, sulfuric acid to optional combination
Salting liquid, propane bitumen, cellulose fibre, grain (useless cereal), HSC (height conversion seed soaking catalytic cracking) residue, petroleum
HSC/ROSE (residual oil supercritical extraction) residue mixed in industry.
In general, to have any different between coke promoters and agglomeration (bonding) auxiliary agent, although for certain raw materials, it can also
There can be the auxiliary agent that can be achieved at the same time two kinds of functions.
It has been found that addition water is often unfavorable in the case where coal kind described here.For example, lignite is usual
With > 45% water content.In order to ensure the high efficiency in briquetting process, it has been found that observing determining (is not too
It is high) water content is meaningful.Particularly, the water content of discovery about 20% is advantageous.Accordingly, it is possible to also will do it preliminary dry
It is dry.
Subsequent briquetting process is specifically in 40 DEG C to 90 DEG C, especially 55 DEG C to carrying out within the temperature range of 65 DEG C.
This agglomeration mode have in terms of will lead to coal briquette produced high compression strength and wear-resistant strength, especially intensity >=
30MPa。
By means of one or more methods described herein (specific agglomeration technique, especially with gently dried and coking
Method combines), the coke or coal for having higher quality relative to raw material can be provided.Even if, can also be in coking
Ensure to keep required briquetting shape, especially cylindrical ice hockey shape.In coking, the quality and volume of coal are shunk
40% to 60%, especially 50%, and be also therefore that it obtains the high compressive strength and wear-resistant strength of required > 30MPa
(coke strenth (CSR) after especially reacting) and hypoergia, CRI (coke reactivity index) value < 55%.The reactivity
The upper limit be necessary because otherwise coal briquette may spontaneous combustion in the presence of air.So far, using described
Low grade coal quality is not possible to reach quality level defined in these limiting values at present.Specifically, method so far and
Equipment already leads to briquetting rupture, even results in the complete destruction of briquetting shape.The variation of quality and volume especially can be with phase
Same ratio occurs.

It is according to the present invention by agglomeration there may be the advantages of and overcome difficulty it is specific as follows:
The high-strength coke for being used for blast furnace is provided;
The raising of coke quality especially produces coke independently of by hot wafering lignite with independently of existing method, independent
In the coke by the briquetting lignite production by case of wet attrition grinding production, and independently of by by pre- granulated drying brown coal
The coke of the briquetting production of coal dust production;
Compared with the conventional method (for example, with liquid, drying is removed by ultra-fine grinding and then the case of wet attrition that crushes is ground
Mill is compared), the cost and complexity of device can be reduced;
Can increase so far limited coke strenth (especially by the pressure by pre- granulated drying brown coal dust production
In block coke produced).
For various raw materials, between the first agglomeration step (perforated plate roller mill) and the second agglomeration step (compression), do
Dry to generate favorable influence, therefore, arrangement each other side by side may be more advantageous than arranging up and down in the same plane.Just
