It is to summarize, therefore necessarily include the simplification, summary and omission of details above；So that those skilled in the art will
, it is realized that the general introduction is exemplary only and is not intended to be limited in any way.As only determined by claims
Justice, become obvious in the non-limiting detailed description that other aspects, inventive features and advantage of the invention will be described below.
Brief description
The present invention is better understood by reference to attached drawing, and makes its numerous objects, features and advantages will be to this field
Become for technical staff obvious.
Fig. 1 is the flow chart for showing the first embodiment of customization coking method in accordance with the principles of the present invention；
Fig. 2 is another flow chart for showing the second embodiment of Fig. 1 method；With
Fig. 3 is the flow chart for showing the pyrolysis that mixture is formed by according to the method for Fig. 1 or 2.
It is described in detail
The detailed description of the embodiment of the present invention presented below should not be used as the limitation to invention itself.On the contrary, many changes
Change in the scope of the present invention defined in claims after can falling within present description.
It will refer to the embodiment of the present invention being illustrated in attached drawing in detail now.As long as possible, drawing and description
It is middle that the same or similar component, behavior (act) or step are censured using the same or similar reference number.Attached drawing is to simplify shape
Formula.
It will be appreciated by those of ordinary skill in the art that in the exploitation of any such actual implementation, such as in any engineering or
In design object like that, it is necessary to numerous decisions for implementation are made, to realize the objectives of developer, such as compliance system
Relevant, the relevant restriction of metallurgy, the restriction can change between different implementations.To those of ordinary skill in the art
It says that this can be the daily guarantee of design, preparation and manufacture, and there is the benefit of present disclosure.
These coking process do not require high-quality coking coal, they are also not limited to only two kinds of carbonaceous material chargings
(input).Further, disclosed method more efficiently uses raw material, because " useless " product or fine powder (fines) can
For generating high quality coke, and thus make contributions for environmental-friendly coke production etc..In addition, at least partially due to subtracting
Lack the time needed for producing the high quality coke and is acknowledged as energy conservation.
Coal for coke production, which is blended in the quantity of coal used, to be changed.It also as the ratio of coal component, grade,
Coking performance and geographic origin and change.Coal selection and blend composition be control coal physics and chemical property it is main because
Element.These factors cause the behavior of sometimes referred to as devolatilization behavior.
It is available to have several mathematical model as the auxiliary of the coal selection for prediction of coke quality.It can be by these (moulds
Type) it is divided into two groups.First group model concentration is dedicated to predicting cold machinery, metallurgy or " met " coke strenth.
Second group model uses CSR and CRI index as coke quality parameter.(the at this when this (application) writes
Writing), not general prediction model is recognized, especially true for customization coke production.Some coals or blend are in base
Significant deviation is shown between the prediction result and actual use of model.
Notably, almost all of coke-oven plant now attempts forecasting coal grade, petrology, stream using certain model
Denaturation can be with ash content chemistry.But unlike presently disclosed invention embodiment, in the past, a series of recuperation of heat furnaces is needed to try
Figure realizes the result by model prediction.In order to attempt to be operated in a manner of environmental-friendly, some furnaces operate under suction,
Without emission in coking.
Fig. 1 is the flow chart for showing the first embodiment of customization coking method in accordance with the principles of the present invention.
In embodiment illustrated, this method starts at oval frame (oval) 100.In oval frame 100
Later, the first process block (process block) and the second process block 102,104 illustrate as in mixer box
(block) merge carbonaceous material in the mixer at 106.
Then mixer ingredient is analyzed at process block 108.In special embodiment, to mixture into
Row customization is to form coke in the pyrolysis step for following pyrolysis step.At decision box (decision block) 110
It is indicated, if answered in a manner of certainly whether custom mix object the problem of, take "Yes" branch and in process block 112
Place customizes.
Customization may include by the shape, size of the carbonaceous fine powder used in pyrolysis, percentage and type etc..For example,
In the case where type of the mixture instruction via the product of following pyrolysis step production, if carbonaceous mixture so refers to
Show, then can be formed as being filled with the firm shell of carbonaceous fine powder before the heating stepses of pyrolysis.
Otherwise, skip process block 112 and by mixture be transferred directly to pyrolysis apparatus process block 114 (its in more detail
It is described in Fig. 3).
Finally, the flow chart of Fig. 1 terminates as indicated by oval frame 116, and customization coke production is completed.
Fig. 2 is another flow chart for showing the second embodiment of Fig. 1 method.But in Fig. 2 embodiment, coking
Technique is since at oval frame 200, in oval frame after following the technique similar with the coking process of Fig. 1 (process)
Terminate at 204.But other materials are introduced into mixer technique (box) 106 by the display of process block 202.The other materials can
For many substances, such as other carbonaceous material, non-carbonaceous material in addition, the multiple combinations of such material etc..
Fig. 3 is the flow chart for showing the pyrolysis that mixture is formed by according to the method for Fig. 1 or 2.For easy understanding, scheme
1 and 2 pyrolysis apparatus step 114 starts at oval frame 300 and is moved to process block 302 to be appropriately formed the mixed of introducing
Close object.After shaper box 302, using diamond shape decision box 304.
If it is determined that mixer ingredient is not yet ready for ready for being pyrolyzed, then as indicated at process block 306, will mix
Clutch ingredient returns to process block 302, for being further formed.
Once diamond (diamond) 304 indicates that mixer ingredient is ready for being pyrolyzed, enter mixer ingredient
Pyrolytic process box 308 simultaneously produces coke at process block 309.
In addition, illustrating separator 310, it is gentle pyrolysed mixture can be separated into tar in separator 310
Body.Decision box 312 is wherein to decide whether the step of there are available tar.If it is, "Yes" branch is then taken to go forward side by side
Enter tar processing process block 314.
Alternatively, or additionally, "No" branch and using gas treatment process box 316 are taken, at gas treatment (box)
After 316, oval frame 318 indicates that this method returns to the figure of front.
When consulting present disclosure, it will be appreciated by those of ordinary skill in the art that other equivalent materials and step can
Substitute the invention to realize the disclosure.
Although embodiment disclosed in various (sheets) has been described in described in detail above and is illustrated in attached drawing, answer
Understand, presently disclosed invention be not limited to disclosed in embodiment, and can take really each element or step numerous arrangements,
Rearrange, modifications and substitutions without departing from invention described herein spirit and desired extent.Appended claims
