    DESCRIPTION OF THE INVENTION 5
    Device for supplying energy sources, iron carriers and additives to the surface of a fixed bed
    Field of Technology 10
    The present application relates to a method for optimizing the production of pig iron in a melter gasifier by continuous and controlled supply of fuels, iron carriers and additives 15 or mixtures thereof to the surface of a fixed bed.
    State of the art
    In the COREX® process usually in a 20 reduction shaft produced sponge (direct reduced iron, DRI) and aggregates over, for example, in a horizontal arrangement star-shaped passing through the peripheral walls of the reduction shaft conveying members, such as screw conveyor, withdrawn and concentric on the arrangement in 25 concentric arrangement Radius around the central axis of the melter gasifier grouped downpipes, from the head into the below the Reduktionsschachtes - usually aligned with this arranged melter carburetor introduced (DRI lines). Energy carriers or the gasification substrate as well as optionally correction substances - such as quartz - are charged centrally in the head of the melter gasifier (coal line). An exception
    This is due to the coke carburization, which is also possible via the shaft and the DRI downpipes. Charging of mixtures of energy carriers and iron carriers into the melter gasifier takes place in parallel with the charging of energy carriers via the coal line.
    In recent times, it has become practice to charge a smaller portion of the - oxidic present - iron carrier, in particular ünterkorn, together with the coal in the melter gasifier, without the COREX tower special devices were created for this purpose.
    This constellation also applies in principle to the FINEX process, even if the fine-grained iron sponge originating from the reduction reactors is not there directly, but only after passing through a compaction (hot 15 compacting) - in which coarser aggregates (hot compacted iron, HCl), enter the melter gasifier. These aggregates are collected in a bunker, which is durchgasbar and thus suitable for a Nachreduktion 20, from which they are transported with analogous to the COREX reduction shaft arranged augers via analogous to COREX arranged downpipes in the melter gasifier. Coal, coke, coal briquettes, aggregates - and possibly special substances such as fine ore - batchwise batchwise, or first continuously and then discontinuously from a lock system, charged from Möllergebäude 30 via conveyor and pressure lock system to the coal storage bin on the coal line , From the coal storage bunker is a continuous promotion of the entire mixture means

    Coal screw via a static or dynamic distributor element in the melter gasifier. With a dynamic distributor, the material mixture can be distributed according to predetermined distribution patterns on the entire Mölleroberfläche - in particular circular or annular -or certain zones of the Mölleroberfläche. However, it is not possible to distribute individual materials or material mixtures differently than the main stream of coal. There is only one coal line, and therefore individual materials or special mixtures of materials can not be promoted separately to the melter gasifier and accordingly not individually distributed in the melter gasifier. The targeted influence on the permeability of the fixed bed in melter gasifier is thus severely limited despite dynamic coal distribution.
    Summary of the Invention Technical Problem
    It is the object of the present invention to provide an apparatus and a method with which individual materials or special material mixtures can be individually distributed according to their effects on the Charbettstruktur and carburetor conditions on the bed surface without a complete, compared to the prior art additional , Charging line is required.

    In the melter gasifier, this charged material is melted by means of an energy source or several energy carriers, any additives which are charged directly to the fixed bed via the head of the melter gasifier, and an oxygen-containing reducing gas and converted into liquid pig iron and liquid slag. At the same time a gas is generated, which is discharged from the head of the melter gasifier and fed on the way via a dedusting again 10 at least one reactor for reducing oxidic iron carrier at least to a large extent as a reducing gas.
    According to one embodiment, a storage bunker for energy carriers is present, whose interior is divided by a partition wall into two subspaces. Each of the subspaces has its own outlet opening through which energy carriers can be removed from it. At each of the two outlet openings a take-off device for the withdrawal of energy sources from the first storage bunker for 20 energy carriers is provided, ie a first take-off device and a second take-off device.
    The second extraction device can open into the first extraction device, or it can open into the charging device of the melter gasifier. 25 This embodiment may, for example, by a
    Two-part coal storage bunker and the provision of two discharge screws are realized.
    According to another embodiment, there are two storage bins 30 for energy carriers. Each of the storage bins has its own outlet opening through which energy carriers can be removed from it. At each of the two outlet openings

    A withdrawal device is provided, that is to say a first withdrawal device for withdrawing energy carriers from a first storage bunker for energy carriers and a second withdrawal device for withdrawing energy carriers from a second storage bunker for energy carriers ,
    The second extraction device can open into the first extraction device, or it can open into the charging device of the melter gasifier.
    This embodiment can be realized, for example, by a second coal storage bunker.
    A take-off device can be designed, for example, as a screw conveyor. 15 The storage bin (s) are filled from the so-called Möller building via a charging line.
    In the embodiment with a storage bunker divided into two compartments, preferably only one batching line is present, which conveys material to the storage bunker 20.

    Also in the embodiment with two storage bunkers, it is preferable to introduce the provided for filling the storage bunker material with only one charging line to the storage bunker, and only shortly before the storage bins provide two in 5 each one of the storage bunker leading end portions of the charging line.
    In this way, both in a conversion of a conventional device to a device according to the invention as well as in new construction of a device 10 according to the invention, the construction and investment costs and the
    Maintenance costs are kept low. The construction and maintenance of several charging lines can thus be avoided.
    The possibilities of use of the device 15 according to the invention are manifold. It can be two materials or two
    Material mixtures in the so-called tower of a COREX® or FINEX® plant, which includes the coal storage bunker, are cached, and then charged mixed or mixed individually. Examples of possible modes of operation are: Charging of coke, for example, carried out separately from a charging of coal, for example, centrally into the melter gasifier. Different enrichment of the charged coal or coal mixture with specific coke
    Ring layers for targeted permeability of the fixed bed. - Permeability of the fixed bed by targeted ring distribution of different fine materials 30 - Maximization Unterkorneinsatz; for example, separate from

    9 - targeted charging of plastic as an energy source to the fixed bed without disturbing permeability over a large area. - For special operating conditions - for example start of a start with operation of a few nozzles - the 5 process conditions can be further optimized by the specific local addition of special raw materials - such as coke.
    According to a further embodiment, an additional extraction device is present at the second storage bin. This additional extraction device is provided for the withdrawal of coarse material, which then - optionally directly, that is, without passing through the charging device - is introduced into the melter gasifier. 15 According to one embodiment, the additional
    Deduction device also suitable to serve for the introduction of problem substances contained in small containers in the melter gasifier.
    With such embodiments it is avoided that 20 lumpy material or the small containers fall into the first or second extraction device, which are for example designed as screw conveyors. The operation of screw conveyors can be disturbed when a threshold for the piece size of the material to be conveyed 25 is exceeded, which may be the case with lumpy material or small containers. Under coarse material is to be understood material whose piece size is above the applicable for the screw conveyor used limit for the piece size of the material to be delivered 30. For example, according to COREX coal specifications, pieces of coal that do not pass the sieve # 63mm are too large.
