Definitions
- the invention is directed to a method and a device for the aftertreatment of the C-containing bottom product obtained in the gasification of carbonaceous fossil fuels in an HTW process in a gravitational direction below the fluidized bed.
- a carbon-containing ash stream (so-called bottom product) is withdrawn at the bottom of the carburettor.
- the bottom product is previously fed to an external furnace.
- the energy use is incomplete and leads to deteriorated degrees of separation in the case of C0 2 separation.
- the object of the invention is to achieve a more extensive oxidation by simple means to increase the carbon turnover in HTW carburetors.
- this object is achieved according to the invention by the supply of an oxidizing agent by impingement of porous, ceramic elements, such as gas purging, foam ceramics od.
- porous, ceramic elements such as gas purging, foam ceramics od.
- a bottom product oxidizer below the fluidized bed With such a procedure is achieved that directly into the resulting bottoms product small distributed oxidizing agents can be introduced, such as C0 2 / steam.
- This procedure also ensures that the bottom product is oxidized to such an extent that the ash leaving the plant corresponds at least to landfill class 2 (TA-Siedlungsanfall, ⁇ 5% TOC).
- a part of the oxidizing agent is introduced via a below the entry of the bottom product in the oxidizer positioned conical element in the bottom product.
- a first frusto-conical element may be e.g. serve as a distributor of the bottoms product in the bottoms oxidizer.
- At least part of the oxidizing agent is introduced into the product to be treated via juxtaposed rinsing stones.
- These flushing stones can have very different shapes, such as frustoconical, cylindrical, hemispheres or the like, without the invention being restricted to a particular design.
- An advantageous embodiment of the invention is that the oxidation ⁇ medium is introduced with frusto-conical purging over the end face and the conical surface.
- oxidizing agent 0 2 / steam or 0 2 / C0 2 o- the like which serves, for example, to avoid stationary ash agglomeration / -versinteronne.
- the oxidizing agent is supplied in at least two levels.
- the invention also provides a device, which is characterized in that for introducing the oxidant open-pore ceramic elements, such as gas purging blocks are provided, which are provided with frustoconical Gas Jesteine such with a gas-permeable end and a gas-permeable lateral surface ,
- the invention also provides that the device is equipped with at least one measuring device for monitoring the C content in the bottom product, wherein the measurement is used in particular to control the discharge organs. Such a measurement of the C content can ensure that the ash leaving the device has the parameters necessary for landfill.
- an embodiment of the invention is also that this measuring device is equipped for non-contact measurement by means of microwaves, including, for example, a measuring device can be used, as published for example by INDUTECH GmbH, Simmersfeld. Of course, other methods of measurement are possible.
- FIG. 1 is a schematic diagram of a fluidized bed gasifier with integrated soil product oxidation
- Fig. 2 is a schematic diagram of a bottom product oxidizer and in
- FIG. 1 shows a circuit diagram with a fluidized bed, generally designated 1.
- carburetor which is downstream in the direction of gravity bottom product oxidation 2, as described in detail below.
- the diagram shows a storage 3, for example, with a rotary valve 4, in which the product to be gasified is first passed through a weighing container 5, then via an entry lock 6 to a storage container 7. Thereafter, the product to be gasified is again fed to the fluidized-bed gasifier 1 via a rotary valve 4a via screws 8 and 8a.
- the gas is passed through a recycle cyclone 9, wherein the gas is fed via a raw gas cooler 10 to a hot gas filter 11.
- the bottom product oxidation in the plant part 2 is supplied with appropriate oxidants, generally designated 12, which may be 0 2 / steam, 0 2 / CO 2 or similar mixtures.
- 2 shows in simplified form the bottom product gasifier 2 with oxidant supply according to arrow 12.
- the introduction of the bottom product is indicated by an arrow 13.
- the discharge of the bottom product indicates an arrow 14.
- a surface formed of truncated cones 16 is indicated in a plane below the conical element 15
- a plane is indicated as a plate 17 with naturally existing apertures.
- This may be, for example, a grid-like element of porous ceramics.
- a plane of frustoconical purging stones or ceramic stones is shown, which can be flowed through at their total area of gas, here also again Sufficient passages are available for the failing bottom product.
- the gas flows are indicated overall with small arrows.
- FIG. 3 A possible different arrangement of ceramic elements is shown in FIG. 3.
- horizontally juxtaposed frustoconical elements are denoted 16a
- vertically arranged frustoconical elements are 16b.
- Pyramid-shaped elements 19 are shown there as well as hemispherical ⁇ shaped elements 20.
