Definitions
- the invention relates to a method for gasifying waste materials containing combustible components in the circulating fluidized bed, taking out the waste materials in a gasification reactor with the addition of Gasified gas in the swirl state, from upper area of the gasification reactor Gas-solid mixture feeds a separator from which Separator removes dusty gas and separates it separated solids and the solids at least partially in the gasification reactor leads back.
- the invention has for its object to ensure in waste gasification that the formation of highly toxic substances, such as especially dioxins and furans, is avoided as far as possible. At the same time, the amount of exhaust gas formed should be kept low. According to the invention, this is achieved in the process mentioned at the outset by carrying out the gasification in the gasification reactor at temperatures in the range from 800 to 1100 ° C.
- gaseous gasification agent which consists of 20 to 90% by volume of oxygen by leaving the separator draws off a dust-containing gas, the content of free O 2 of which is at most 0.5% by volume, that the gas drawn off from the separator is partially burned in a cracking reactor which is at the same time from 70 to 100% by volume of oxygen-rich O 2 existing gas is supplied, that temperatures in the range of 1200 to 1600 ° C are maintained in the cracking reactor and liquid slag is generated which is discharged from the cracking reactor, and that the cracking gas formed in the cracking reactor is cooled in at least one cooler with a cooling rate of at least 100 Cools down to a maximum temperature of 300 ° C per second.
- a gaseous gasification agent is understood to mean all gases supplied to the gasification reactor, but with the exception of H 2 O in liquid form or in vapor form.
- the O 2 content of the total amount of gaseous gasifying agent is preferably at least 50% by volume.
- the oxygen necessary for the partial oxidation in the gasification reactor is supplied by the gaseous gasification agent preferably in the form of air enriched with oxygen or technically pure oxygen.
- the amount of inert gas which leaves the gasification reactor in the gas-solid mixture is kept low and the dust-containing gas drawn off from the separator has a calorific value of approximately 4000 to 8000 kJ / Nm 3 . If the calorific value of this gas is high enough, there is no need to add additional fuel in the cracking reactor.
- the waste materials to be gasified which can be, for example, municipal or industrial waste, are fed in line (1) to a gasification reactor (2), where they come into contact with hot gases and particles in the state of the circulating fluidized bed.
- Oxygen-containing fluidizing gas is introduced in line (3) and passed through a distribution chamber (4) with a grate (5) into the fluidized bed of the reactor (2).
- additional oxygen-rich gas is added to the fluidized bed above the grate (5), the O 2 content of this gas being higher than in the gas in line (3).
- the O 2 content in the gas is 50 to 90% by volume (calculated as anhydrous).
- the gasification in the reactor (2) takes place at temperatures of 800 to 1100 ° C and mostly at temperatures in the range from 850 to 1000 ° C.
- Ash is removed through the line (6) withdrawn and a separating device (60), e.g. one Sieve. Rough ash parts are drawn in the Line (61) and the fine ash parts are passed through the line (62) to a grinding (63), in order to then if desired, on the transport route (12a) To be able to give up the gap reactor (13).
- a gas-solid mixture leaves the reactor through the channel (8) and flows into a cyclone separator (9), from which dust-containing gas with a free O 2 content of at most 0.5 Vol .-% is withdrawn through line (10).
- a cyclone separator (9) from which dust-containing gas with a free O 2 content of at most 0.5 Vol .-% is withdrawn through line (10).
- Separated solids are returned from the lower area of the separator (9) through line (11) to the reactor (2).
- the line (11) can also have a side draw (12) for removing an excess of solids. This excess of solids can also be passed into the gap reactor (13) on the transport path (12a).
- the dust-containing gas drawn off in the line (10) from the separator (9) is fed to the cracking reactor (13), where partial combustion takes place at temperatures in the range from 1200 to 1600 ° C. and preferably 1250 to 1500 ° C.
- oxygen-rich gas containing 70 to 100% by volume of O 2 is introduced, which can also be technically pure oxygen.
- a line (15) for additional fuel, for example natural gas, is also provided. Partial combustion in the cracking reactor (13) produces liquid slag that flows downwards. Hot cracked gas leaves the reactor (13) together with liquid slag through the channel (17).
- the cracking reactor (13) can be, for example, a combustion chamber, a melting cyclone or a hearth furnace.
- many pollutants introduced in line (10) are destroyed at the high temperatures reached there, and in particular also higher hydrocarbons are split, so that the cracked gas in channel (17) is practically free of hydrocarbons with more than 4 carbon atoms per Molecule is.
- the cooled gas from line (20) is now still further cleaned by washing water, taking it down through a jet washer (28) up through the channel (29) in an aerosol washer (30) through line (31) a venturi washer (32), down there to the channel (33) and then flows up through the spray tower (34).
- the Spray tower (34) is led through line (35) Fresh water to which you also add sodium hydroxide solution can, in particular, chlorine in the gas to be treated tie. It is useful to have one in the spray tower (34) Pack (36) for intensifying the Provide gas-liquid contact.
- the gas that the Leaves spray tower (34) through line (37) is through an activated carbon filter (38) passed to mercury remove before it is in line (39) further, per se known cleaning stages or a combustion, e.g. in a power plant.
- Another Possibility is to gas the line (37) first of all to a known desulfurization undergo before passing it through the filter (38), however this possibility was not shown in the drawing considered.
- Fig. 1 are water supply lines with the Reference number (40) and cooler with reference number (41) Mistake. Used water in the pipes (42) and (43) runs, gets into the settling container (44). Out partially clarified water is fed to this container Reuse in the jet washer (28) and Aerosol washer (30) pulls wastewater through the Line (45) and removes sludge through the Line (46). Mud and sewage are not in shown further processed separately.
- a wastewater-free process for cooling the hot Cracked gas that is generated in the reactor (13) is with the help the schematic representation of FIG. 2 explained.
- the amount of water is so on Temperature and the amount of gas matched that the all of the water along with the chilled gas in the form of Water vapor is drawn off through line (52).
- Solids that dry out at the bottom of the spray tower (50) collect, are removed through line (48).
- the Gas of the line containing water vapor and dust (52) is passed through a filter device (53) in which e.g. around a bag filter or an electrostatic filter can act; you can also have several here Combine filter types. Dust-free gas flows in the Line (54) and is the other, known per se Gas cleaning supplied, which is not shown here.
- a heavy cake containing heavy metals is obtained in an amount of 50 kg / h.
- the gas in line (20) which is produced in an amount of 10800 kg / h, has a calorific value of 5.7 MJ / Nm 3 .
- the slag drawn off in the line (24) is glazed by the pretreatment and can therefore be deposited without any problems.
