Definitions
- the invention relates to a process for the gasification of waste materials containing combustible constituents in the circulating fluidized bed, the waste materials being gasified in a gasification reactor with the supply of oxygen-containing gas in the fluidized state, a gas-solid mixture being fed to a separator from the upper region of the gasification reactor Separator removes dust-containing gas and discharges separated solids separately and at least partially returns the solids to the gasification reactor.
- US Pat. No. 4,469,050 describes the combustion or gasification of carbonaceous material or also waste in the circulating fluidized bed.
- the reaction takes place in a fluidized state with the supply of air in a reactor which is followed by a cyclone separator.
- the separated solids are at least partially returned from the cyclone to the lower area of the reactor.
- 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.
- the content of free O2 is at most 0.5 vol .-%, that one partially burns the gas withdrawn from the separator in a cracking reactor, which is simultaneously supplied with an oxygen-rich, 70 to 100 vol .-% of O2 existing gas that one maintains temperatures in the range of 1200 to 1600 ° C in the cracking reactor and produces liquid slag which is derived from the cracking reactor, and that the cracking gas formed in the cracking reactor in at least one cooler with a cooling rate of at least 100 ° C per second cools down to a temperature not exceeding 300 ° C.
- Gaseous gasification means all gases supplied to the gasification reactor, but excluding H2O in liquid or vapor form.
- the O2 content of the total amount of gaseous gasifying agent is preferably at least 50% by volume.
- solid gasification residues can be rendered inert by slagging.
- Ground slag, own ash, sand or another inert granulate are preferred as the fluidizing medium in the gasification reactor.
- 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. This keeps the amount of inert gas that the gasification reactor in the gas-solid mixture low leaves and the dust-containing gas drawn off from the separator has a calorific value of about 4000 to 8000 kJ / Nm3. If the calorific value of this gas is high enough, there is no need to add additional fuel in the cracking reactor.
- the further treatment of the cooled cracked gas which still contains pollutants, e.g. Contains mercury, sulfur compounds, as well as chlorine and nitrogen compounds, is carried out in a known manner. Gas cleaning is facilitated if the cooled cracked gas of an existing combustion device, e.g. to a power plant, the gas cleaning devices of which are also used in this case.
- pollutants e.g. Contains mercury, sulfur compounds, as well as chlorine and nitrogen compounds
- the waste materials to be gasified which are e.g. can be municipal or industrial waste, are fed to the 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).
- the O2 content in the gas is 50 to 90% by volume (calculated as anhydrous).
- the gasification in the reactor (2) takes place at temperatures from 800 to 1100 ° C and mostly at temperatures in the range from 850 to 1000 ° C.
- Ash is drawn off through line (6) and sent to a separator (60), e.g. a sieve. Coarse ash parts are drawn off in line (61) and the fine ash parts are added through line (62) to a grinding (63), in order then, if desired, to feed them to the splitting reactor (13) on the transport route (12a) can.
- 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 O2 content of at most 0.5 vol .-% is withdrawn through line (10).
- Separated solids are from the lower area of the separator (9) through the line (11) to Reactor (2) returned.
- 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.
- line (14) oxygen-rich, 70 to 100 vol .-% of O2 gas is introduced, which can also be technically pure oxygen.
- 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 gasification reactor (2), together with the gasification agent feeds as little inert gas as possible. Solids that get into the reactor (13) on the transport path (12a) are melted there.
- the shock-like cooling of the hot cracked gas takes place in the cooler (18) by excess cooling water which is injected into the line (19).
- the slag is solidified into granules. Cooling speeds, in particular in the temperature range between 800 ° C. and 300 ° C., of 100 to 300 ° C. per second and more are achieved in the cooler (18).
- the cooled cracked gas saturated with water vapor, which leaves the cooler in line (20) usually has a temperature in the range from 60 to 95 ° C.
- the cooled gas of line (20) is now further cleaned by water washes, whereby it is descended through a jet washer (28), through channel (29), upwards in an aerosol washer (30), through line (31) to a venturi washer (32), there flows down to the channel (33) and then upwards through the spray tower (34).
- Fresh water is fed to the spray tower (34) through line (35), to which sodium hydroxide solution can also be added, in particular to bind chlorine in the gas to be treated.
- pack (36) to intensify the Provide gas-liquid contact.
- the gas, which leaves the spray tower (34) through line (37), is passed through an activated carbon filter (38) to remove mercury before it is passed through further, known cleaning stages or combustion in line (39). eg in a power plant.
- Another possibility is to subject the gas in line (37) to a desulfurization known per se before passing it through the filter (38), but this possibility was not taken into account in the drawing.
- Fig. 1 water supply lines are provided with the reference number (40) and coolers with the reference number (41). Used water that runs off in the lines (42) and (43) reaches the settling tank (44). From this tank, partially clarified water is returned for reuse in the jet washer (28) and aerosol washer (30), waste water is drawn off through line (45) and sludge is removed through line (46). Sludge and waste water are treated separately in a manner not shown.
- a wastewater-free process for cooling the hot cracked gas which is produced in the reactor (13) is explained with the aid of the schematic illustration in FIG. 2.
- the hot gas which leaves the reactor (13) in the channel (17) together with liquid slag, cf. Fig. 1, introduced into a spray tower (50) from above, in which water is sprayed at the same time, which is introduced in line (51).
- the amount of water is matched to the temperature and the amount of gas so that all the water is drawn off together with the cooled gas in the form of water vapor 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 (52) containing water vapor and dust is passed through a filter device (53), which can be, for example, a bag filter or an electrostatic filter; you can also combine several filter types here. Dust-free gas flows off in line (54) and is fed to the further gas cleaning which is known per se and which is not shown here.
- a filter device which can be, for example, a bag filter or an electrostatic filter; you can also combine several filter types here. Dust-free gas flows off in line (54) and is fed to the further gas cleaning which is known per se and which is not shown here.
- the variant of the treatment of the exhaust gas of the line (20) described here together with FIG. 1 can be modified by such known measures as are known from plants for waste incineration.
