Definitions
- the invention relates to a method and a plant for sintering metal-containing materials such as iron ores or manganese ores, in particular oxidic or carbonate ores, on a sintering machine with sintered exhaust gas recirculation.
- metal-containing materials such as iron ores or manganese ores, in particular oxidic or carbonate ores
- the sintering of metal-containing materials such as iron ores or manganese ores, in particular oxidic or carbonate ores, by means of sintering machines.
- the sintering mixture which consists of the metal-containing material, return material, solid fuel, aggregates, etc.
- the sintered mixture is ignited in an ignition furnace on its surface.
- oxygen-containing gases are passed as process gas through the sintering mixture, whereby the sintering front migrates from the surface of the sintering mixture in the direction of the sintering belt surface.
- the gases used as process gas are, for example, fresh air, exhaust air from a sintering cooler, air used for predrying the sintering mixture, a mixture of several of these gases, or a mixture of one or more of these gases with technical oxygen.
- the sintering belt is moved from the loading point in the direction of the discharge point. During transport on the sintering belt, the entire sintered mixture is sintered through and leaves the sintering belt as a hot finished sinter at the discharge point. The hot finished sinter is cooled in a subsequent sinter cooler.
- Sintering machines can be designed, for example, as traveling grate sintering machines, in which the process gas is sucked through the sintering mixture by applying a negative pressure to the suction boxes below the sintering belt by means of blowers.
- the temperature and oxygen content of the resulting sintering waste gas change in normal operation.
- the temperature of the sintered exhaust gas increases along the sintering belt.
- the oxygen content of the sintered exhaust gas initially decreases along the sintering belt, in order to increase again after reaching a minimum.
- the temperature is the sintering waste gas in the front first portion of the sintering belt below 100 0 C and increases up to the rear portion to over 300 0 C.
- the sintered exhaust gas contains, inter alia, evaporated water from the sintering mixture, CO 2 and CO from the sometimes incomplete combustion of the fuel and calcination operations, further from the combustion of sulfur or sulfur contained in the fuel or ore sulfur oxides SO x , and nitrogen oxides NO x , dioxins, furans, dust.
- the removal of pollutants is necessary to minimize the environmental impact.
- a reduction in the amount of exhaust gas to be removed from a sintering machine or the pollutant load contained in the exhaust gas facilitates the exhaust gas purification.
- JP-53-004706 describes a partial recycling of sintering exhaust gases to the sintering mixture, wherein the cold sintering exhaust gas is passed from the front first section of the sintering belt to the hot sintering exhaust gas from the rearward third section before combining both gases.
- the transport path which has to cover the cold sintering exhaust gas until it merges with the hot sintered exhaust gas, is very long.
- the acids formed from the nitrogen oxides NO x , sulfur oxides SO x and water vapor contained in the sintering offgases due to the falling below the acid dew points occur.
- the condensing acids are highly corrosive.
- This object is achieved in that the hot sintered exhaust gas from the third section, which causes no corrosion problems in normal operation, if possible is brought close to the first section before it is combined with the sintered exhaust gas from the first section.
- the present invention is therefore a process for sintering metal-containing materials such as iron ores or manganese ores, in particular oxidic or carbonic ores, on a sintering machine, in the oxygen-containing process gas in three successive sections of the sintering belt, of which the first on one side of the sintering Joining zone and the third ends at the discharge end of the sintering belt is passed through the sintering mixture, and collected in each of the sections sintering gas is collected and discharged separately in suction boxes, and the sintered exhaust gas from the first section and the sintered exhaust gas from the third section as Process gas is supplied to the second section, and the resulting in the second section sintered exhaust gas is discharged as exhaust gas from the sintering machine, and the hot ready sintered sintered after being discharged from the sintering belt, characterized in that the sintered exhaust gas from the third section to Sinte Rabgas is transported from the first section and combined in a mixing area with this to a mixed gas, wherein the transport distance of the
- the length of the sintering belt is divided into three consecutive sections.
- the first section begins, viewed in the transport direction of the sintering mixture, subsequently to the application zone, the third section ends at the discharge end of the sintering belt.
- the second section is bounded by the first and third sections.
- the division of the sections is carried out so that the exhaust gas amount of the sintering machine is minimized and the process gas for the second section in normal operation, optionally after the addition of exhaust air from a sinter cooler and / or fresh air and / or pre-drying of the sintering mixture used air and / or technical oxygen to the mixed gas, a certain temperature and a certain oxygen content.
- the minimum temperature is 90 0 C, preferably from 100 0 C, and usually the highest temperature is up to 15O 0 C, preferably up to 130 0 C.
- the lower limit for the oxygen content is 15 vol%, preferably 17% by volume, but it is also Oxygen levels of up to 20% by volume or higher possible.
- This temperature of the process gas for the second section it is ensured that the risk of corrosion in the system parts in contact with it is kept low.
- This oxygen content ensures that a good sintering quality is achieved.
- the highest possible oxygen content of the process gas for the second section is preferred.
- the first section of the sintering belt usually occupies 5-25% of the length of the sintering belt, preferably 10-20%.

- the sintered exhaust gas from each section of the sintering belt is collected and discharged separately from the sintering exhaust gas of the other sections in the suction boxes associated with the respective section, whereby the discharge of the sintering exhaust gas can be regulated preferentially.
- the sintered exhaust gas from the third section is transported to the sintered exhaust gas from the first section and combined with it in a mixing area to a mixed gas.
- the transport distance of the sintering waste gas from the third section to the mixing area is greater than the transport distance of the sintering waste gas from the first section to the mixing area. Since the path which the cold sintered exhaust gas has to travel from the first section to the mixing zone should be as small as possible, the sintered exhaust gas from the third section should be combined with the sintering exhaust gas from the first section as close as possible to the first section. It is therefore particularly preferable that the sintered exhaust gas from the first section directly below the first section is combined with the sintered exhaust gas from the third section. Depending on the Structural conditions of the sintering machine, it may also be necessary to arrange the mixing area a little further away from the first section.
- the mixed gas obtained by combining the sintered exhaust gases from the first and third sections is supplied to the second section as a process gas for the second section.
- the lengths of the sections in the specified ranges can be varied and thus the properties of the mixed gas or of the process gas for the second section can be changed.
- the entire sintering off-gas from the third section is combined with the entire sintering off-gas from the first section.
- a portion of the sintering exhaust gas of one section is fed to the sintering exhaust gas of an adjacent section.
- the boundary region is to be understood as meaning an area which extends on both sides of the boundary between the sections in each case over a length of up to 30% of the length of the respective section into the two adjacent sections.
- Oxygen content of the process gas for the second section of exhaust air from a sinter cooler and / or fresh air, and / or air used for predrying the sintering mixture and / or technical oxygen are added.
- the oxygen-containing process gas for the first and / or third section for example, fresh air, exhaust air from a sintered cooler, used for predrying the sintering mixture air, a mixture of several of these gases, or a
- the amount, temperature and oxygen content of the sintering waste gases of the individual sections and thus of the mixed gas or of the process gas for the second section can be varied in the desired manner.
- the sintered exhaust gas from the second section is heated with the aid of the sintering exhaust gas from the third section, without the two sintered exhaust gases mixing.
- the temperature increase the risk of corrosion due to the condensation of acids as a result of their dew point being undershot is reduced in the lines leading the sintered exhaust gas from the second section.
- the overall conduit is divided in its interior by longitudinally extending partitions into individual gas guide channels so that the hot sintered exhaust gas from the third section can not mix with the cooler sintered exhaust gas from the second section, but some of its heat to the sintered exhaust gas from the second section can transfer.
- the dusts arising from the sintering exhaust gases of the various sections can be separated in a gas-tight manner, for example by means of chutes with gas-tight dust locks, from which the sintering exhaust gases leading gas guide channels are discharged.
- the combined sintered exhaust gases from the second section are removed as exhaust gas from the sintering machine.
- a colder sintering waste gas is introduced into a warmer sintered waste gas or into the combined warmer sintering waste gases.
- the mixed gas is dedusted before use as a process gas for the second section.
