Description

Method and apparatus for loading iron-bearing material

The present invention relates to a method for charging a material comprising an iron carrier material into a melter gasifier of a melt reduction plant.

In the case of melt reduction processes for producing pig iron in a melt gasifier, such as for example COREX® or FINEX®, materials containing additives as well as carbonaceous materials and iron carrier materials are charged into the melt gasifier. The carbonaceous material is gassed with oxygen to form a reducing gas and releases the heat necessary to melt the iron-bearing material.

The carbonaceous material is, for example, agglomerate coal or carbonaceous briquettes; Which is stored at ambient temperature in a storage vessel for the carbonaceous material from which the carbonaceous material is introduced into the melter gasifier.

In the context of this specification, the term "iron-supported material" includes oxidized, e.g., oxide, and reduced, i. Iron can be present in the iron-supported material in two forms; Thereafter, for example, reference is made to a pre-reduced iron-supported material, which has not yet been completely reduced in relation to the metal form, but which has already been substantially reduced compared to the previous state. It may also exist only in one of two forms.

For example, for FINEX®, the iron carrier material is typically hot compacted iron (HCI). The iron support material may also be HBI (hot briquetted iron) or, preferably, a hot, so-called direct reduced iron (DRI, also referred to as sponge iron) have. In the case of FINEX, it may be possible to load HBI or DRI, especially when the hot or cold HCI is not available, especially when starting or stopping the plant. It may also be a material with a metallization or reduction degree that is not yet qualified as HBI or HCI or DRI. HBI is a hot pressed iron carrier material with a very high proportion of metallic iron - often greater than 90% metallization - and a density of about 5 g / cm ³ , which allows, for example, transport by vessel. The material is separated into brittle forms, usually in excess of 25 mm, i.e. in aggregate form. HBI is pressed at a high temperature of, for example, over 650 ° C, but may be fed into the FINEX® process in a cold form after cooling and transportation.

HCI is an iron-supported material that has a lower ratio of metallic iron compared to HBI and is hot pressed with aggregates. Here, the HCI has a temperature of about 550 to 650 ° C. Its density is lower than 4 g / cm ^3. In the pig iron production process, HCI is further processed immediately after production, which is used in a form favorable to the melter gasifier, which is comminuted by a crusher. DRI is an unpressured iron-supported material with a high proportion of metallic iron similar to HBI, since HBI is pressed into DRI.

In the case of COREX®, the iron carrier material is, for example, a high temperature, so-called directly reduced iron (DRI), or a corresponding iron carrier material with metallization that is not yet qualified as DRI.

In the COREX 占 process, the iron carrier material is discharged from a reduction shaft that is gas treated with a hot reducing gas, and is transported by gravity into the melt gasifier via chutes, and, if appropriate, distributor flaps. For the prior embodiments of the FINEX 占 process, in the corresponding procedure, the fine particulate iron support material obtained from the fluidized beds of the FINEX 占 process pressed to form an iron carrier material, for example HCI-HCI, Called HCI bean gas treated with a high temperature reducing gas, into a melter gasifier. The purpose of the gas treatment is to preheat and reduce the iron-supported material, respectively.

Pyrolysis of coal or carbonaceous briquettes at elevated temperatures results in the formation and release of volatile hydrocarbons and tar. Thus, the carbonaceous material can not be stored in the storage vessel together with the hot iron-bearing material, because the formation and release of volatile hydrocarbons and tar, caused by contact with the hot iron-bearing material, As will the cases of adhesion and clogging in the lines carrying the material to the melt gasifier, or in the pressure compensation lines.

The charging of the carbonaceous material and the iron-supported material into the melter-gasifier has generally been carried out separately until now. As an example, a carbonaceous material is fed from a storage vessel for a carbonaceous material through screw conveyors to a distribution apparatus attached to the center of the dome of the melter-gasifier, wherein the carbonaceous material is introduced into the melt gasifier And is distributed over the cross-section of the melter-gasifier. As an example, the iron carrier material is introduced into the melt gasifier through a plurality of chutes arranged over the circumference of the dome of the melt gasifier.

The separate addition of the carbonaceous material and the iron carrier material into the melt gasifier creates high costs when constructing and maintaining the plant parts required for separate addition. Also, in the case of separate additions, the carbonaceous material and the iron carrier material are not distributed under sufficient control in the material bed of the melter-gasifier - for example, the vertical islands of the iron carrier material can be formed, It has a negative effect on the process.

In EP0299231A1 it is known to charge carbonaceous material and iron carrier material into the melt gasifier centrally through the same opening. In the case of such a central charge in accordance with EP0299231A1, the preheating and reducing processes in the melt gasification process, such as the so-called "dead man" It is disadvantageous that the material is supplied correctly. In addition, the finer and heavier material is concentrated and held in the central region of the material bed as a result of the separation processes, while the rougher and lighter material moves in the direction of the peripheral region. Thus, the mixture charged across the bed of material is separated again in a partially and uncontrolled manner.

WO2012156243 also discloses a method for charging aggregate carbonaceous material and hot iron bearing material into a melt gasifier of a melt reduction plant. In such a case, the aggregate carbonaceous material and the hot iron-bearing material are combined in a variable ratio before and / or during entry into the melt gasifier and distributed by a dynamic distributor over the cross-section of the melt gasifier.

In this case, the iron-bearing material is supplied from a non-gassed storage vessel, unlike the reducing furnace or HCI beans, respectively, described above in connection with the COREX® method or the prior FINEX® method. This has the disadvantage that, for example, when there are problems with the delivery of HCI, the melter gasifier can not be easily operated using other types of iron-supported materials with considerably lower degrees of reduction, such as agglomerate iron ores or pellets . Thus, these problems will have the effect that the operation of the melter gasifier must be stopped at that moment and then restarted at a later time, which signifies considerable expense. Although the use of suitable iron-supported materials on coal lines is principally possible, this would require costly acquisition of suitable materials with a high proportion of metallic iron.

The problem addressed by the present invention is to provide a method and apparatus for the production of a high temperature iron-bearing material and a material comprising a carbonaceous material, which can be handled more flexibly than the prior art in connection with the availability of various types of iron- And to provide methods and devices for charging.

This problem is solved by a method for charging an iron-bearing material and a material containing a coagulated carbonaceous material into a molten gasifier of a melt reduction plant, wherein the iron-bearing material comprises a shaft , And then extracted into the buffer vessel at a substantially constant volumetric flow rate and then introduced into the buffer vessel at a substantially constant volumetric flow rate and then fed to the buffer vessel through a section of the melt gasifier at a variable volumetric flow rate from the buffer vessel Wherein the iron-bearing material and the aggregate carbonaceous material are combined before entering and / or during entry into the melt-gasifier, and the iron-bearing material and the cohesive carbonaceous material are combined, And the ratio of quantities is variable.

The shaft is gas-treated with reducing gas; As an example, it may be a reductive furnace or HCI bean.

"Reduced" means that the degree of reduction of the iron-supported material is increased relative to the degree of reduction upon introduction into the shaft. When extraction from the shaft is carried out, a reduction degree of at least 50%, preferably at least 70%, is preferred. The degree of reduction (RD) is a measure of the decomposition of oxygen from the oxide:

RD = (1- (O / (1.5 * Fe _tot ))) * 100.

Metallization (MG) is defined as:

MG = Fe _met / Fe _tot * 100.

In the expression "a buffer container", "a" is intended to be an indefinite article, not a number. There may be a plurality of buffer vessels, or else only a single buffer vessel may be present. Preferably, a plurality of buffer containers are present.

In the process according to the present invention, the shaft is preferably operated under substantially constant conditions, including for example a substantially constant volumetric flow rate during the introduction of the iron-bearing material and a substantially constant volumetric flow rate of the reducing gas. In order to ensure a substantially constant residence time in the shaft, it must be confronted with a substantially constant volumetric flow rate during extraction of the iron-bearing material from the shaft. Variable volumetric flow rate during extraction from the shaft is undesirable and involves problems in controlling the processes in the shaft; By way of example, dust can be locally overly deposited, thereby interfering with gas flow, resulting in interruptions in volumetric flow rates. It should be understood that "volumetric flow rate" refers to the volume transported per unit time from position (A) to position (B). In this case, "almost constant volumetric flow rate" should be understood in the plant technical context and includes deviations of up to +/- 10% from the values required for a given operating condition, such deviations being, for example, Or by control and / or control over a given operating state, as determined by the type, pressure, and temperature of the materials. In this case, "almost constant" represents the respective operating phase. Various operating steps may be required; For example, depending on the availability and quality of the iron-bearing material and / or the type of carbonaceous material and / or reducing gas, the operator may change parameters of one operating phase to parameters of another operating phase, This may possibly require a longer residence time on the shaft than was necessary in previous operating steps.

The iron-bearing material extracted from the shaft is introduced into the buffer vessel, and thereafter, a material containing iron-bearing material extracted from the buffer vessel at a variable volumetric flow rate from the buffer vessel is distributed over the cross-section of the melt- Is supplied to the dynamic distribution device.

In contrast to extraction from the shaft, the volumetric flow rate during delivery from the buffer vessel to the dispensing device is not nearly constant, but is variable instead. Depending on the desired distribution pattern of the melt gasifier, more or less iron-bearing material loading may be desirable so that more or less iron-bearing material can be fed to the distribution device. Correspondingly, the volumetric flow rate outside the buffer vessel is variable, where "variable" is understood to mean opposite to a constant. Since the introduction into the buffer vessel is performed at a substantially constant volume flow rate, the level of the iron-supported material in the buffer vessel varies during operation. The dimensions of the buffer vessel should be selected in such a way that it is not completely empty and does not overflow under normal operating conditions of the shaft and melt gasifier.

A certain minimum fill level of the buffer vessel is preferred because the iron carrier material then forms a barrier for gas flow from the melt gasifier to the shaft.

In order to avoid the problems associated with starting the stationary iron material supply devices, it is desirable to ensure that the volume flow rate from the buffer vessel does not fall to zero - that is, it remains greater than zero.

The proposed method makes it possible to combine a substantially constant volumetric flow rate with a variable volumetric flow rate from the shaft during distribution in the melter gasifier. Thus, it is possible to easily adjust the distribution pattern without adversely affecting the extraction from the shaft. Also, since it is possible to reduce and / or preheat the gas-treated shaft, the present method can more flexibly respond to the availability of various types of iron-supported materials.

The operating mode according to WO2012156243 is not suitable for feeding material from the gas treated shaft since the flow of material can vary greatly there and possibly also stop there.

The term "melt gasifier" does not include a furnace. In the furnace, layers of iron carriers and coke with essentially additives are added from above under ambient conditions. Pyrolysis and degassing of coal are not carried out in furnaces, but instead are already carried out during the production of coke which is charged into the furnace. Temperatures at the furnace inlet are about 80 to 250 ° C.

In contrast, in the case of the melt gasification process of the melt gasifier according to the present invention, the charged carbonaceous material is not coke but the charged carbonaceous material is pyrolyzed in the melter gasifier. In the region where the material is loaded into the melt gasifier, the temperatures present in the melt gasifier dome are about 1000 ° C.

The iron-supported material includes an iron element and / or iron oxide. The iron-bearing material may be present in the form of agglomerates of greater than 6 mm for the purposes of the present application, or may be in the form of aggregates, for example under technical sieving or under-sizing due to upstream production steps such as, for example, By weight, wherein undersizing is understood to mean that the particle size is less than 6 mm. Examples are iron-supported materials such as HCI, DRI, HBI, quartz, pellets, and sintered materials. Alternatively, the iron-supported material may be a so-called, if appropriate agglomerate, fine particle as measured as a sinter feed, preferably less than 10 mm, when used in FINEX® or FINEX®-DRI prior to hot compacting exist.

Included is preferably a high temperature iron support material. "High temperature steel support material" should be understood to mean an iron support material at a temperature of more than 100 DEG C, preferably more than 200 DEG C, particularly preferably more than 300 DEG C.

The reducing gas is preferably hotter than the iron-supported material at temperatures above 600 ° C, preferably above 700 ° C, particularly preferably above 750 ° C. By the high-temperature reducing gas, not only the iron-supported material can be reduced but also can be preheated to form a high-temperature iron-supported material. Similarly, agglomerates that may be present may be calcined.

The kinetic dispensing device is understood to mean a dispensing device that can be moved in a controlled manner during dispensing operation. As a result, the outlet opening of the kinetic dispensing device can be moved to various positions. Correspondingly, the material may be channeled to various locations of the material bed in the melt gasifier.

By way of example, the kinetic dispensing device may be a rotary suit or a load bal- anster, which may be moved in this manner, such that its exit opening draws, for example, circular or spiral, or optionally predefined tracks, It is also possible that the tracks are selected.

It is advantageous that the movement pattern of the dynamic distribution device is variable.

The material also includes aggregate carbonaceous material, wherein the iron carrier material and the aggregate carbonaceous material are combined prior to and / or during entry into the melt gasifier and the combined amount of iron carrier material and aggregate carbonaceous material Are variable.

The combined amounts of the iron-bearing material and the aggregate carbonaceous material are distributed over the cross-section of the melt-gasifier by a kinetic distribution device, and preferably the ratio of the combined amounts of the iron- Is set according to the position of the dispensing device.

To this end, the supply of iron material and / or the supply of carbonaceous material to the dynamic distribution device is controlled and / or adjusted depending on the position of the kinetic dispensing device.

Within the context of the present application, in the process according to the invention, for additives such as limestone and / or dolomite and / or quartz which are also charged into the melter gasifier, preferably through iron carrier routes No further details are provided.

In such a process, the melter gasifier must have fewer plant parts and openings for charging than if the aggregate carbonaceous material and the iron carrier material are separately introduced into the melt gasifier. The co-charging of agglomerated carbonaceous material and preferably high temperature, iron carrier materials may be achieved through the use of an uncontrolled, undesired < RTI ID = 0.0 > Thereby avoiding the problem of uneven distribution. In addition, expenditure incurred by constructing and maintaining the plant parts necessary for separate charging can be avoided.

With regard to other embodiments and related advantages of co-charging iron-bearing material and agglomerated carbonaceous material by a dynamical distribution device when setting the combined amounts according to the position of the dynamic distribution device, reference is made to WO2012156243 , The entire contents of which are also incorporated into the disclosure of this application.

The present application is also directed to an apparatus for charging a material comprising an iron-bearing material and an aggregate carbonaceous material into a melt gasifier of a melt reduction plant, the apparatus comprising: at least one shaft gassed with a reducing gas; And / or an extraction device for extracting the preheated iron-bearing material to the outside of the shaft at a substantially constant volume flow rate, an introduction device for introducing the extracted iron-bearing material into the buffer vessel, Having a dynamic distribution device for dispensing iron-bearing material from a buffer vessel and also having iron material supply devices for feeding iron-bearing material from a buffer vessel to a dynamic distribution device at variable volumetric flow rates, There is also a storage vessel for the vaginal material and the aggregate carbonaceous material is removed from the storage vessel by dynamics That the supply apparatus for supplying a variable-volume flow to the dispensing device is also present, to a device.

Where control or regulation means in terms of changes in volumetric flow rate. If the iron material feeder is a screw conveyor, the device for controlling and / or adjusting may affect the rotational speed of the screw conveyors, for example to change the volumetric flow rate.
