Device for the thermal processing of pollutant-containing organic waste for the production of gas, oil and activated carbon

摘要

Apparatus for the thermal processing of pollutant-containing organic waste for the production of gas, oil and activated coke, in which 1.1. the digestion complex consists of a dryer (2), the main reactor (8) and a coke reactor (11), 1.1.1. in which the dryer (2) has a feeding device (1) through which the waste (IN) can be fed to the dryer (2) and 1.1.1.1. the dryer (2) is surrounded by a heating jacket (3) through which the waste (IN) can be heated to a drying temperature of 80 ° C to 120 ° C, 1.1.2. in which the main reactor (8) is connected to the dryer (1) via a material lock (4) through which the dried waste (IN) can be transferred to the main reactor (8), 1.1.3. in which the main reactor (8) is surrounded by a heating jacket (3) through which the waste (IN) is heated to a temperature of 350 ° C to 420 ° C, 1.1.3.1. wherein the main reactor (8) includes a liquid feed (6) through which a molten liquid consisting of waste oil (aÖ), tar (T) and a first aggregate mixture (ZA) can be added to the waste (IN), 1.1.4. in which a further material lock (9) connects the main reactor (8) and the coke reactor (11), so that the waste (IN) can be transferred into the coke reactor (11) after the reaction with the molten liquid, 1.1.5. in which the coke reactor (11) has a further heating jacket (12), by means of which the reaction mixture supplied from the material lock (9) can be heated to a temperature of 500 ° C. to 600 ° C. by means of purified process offgases, 1.1.5.1. wherein in the coke reactor (11) a conveying device, preferably in the form of a screw conveyor (10), is present by which the reaction mixture is conveyed from the material lock (9) to the coke preparation (13-16) and during which it is thermally separated in coke and gas, 1.2. coke preparation (13-16) from the coke separator (13), coke cleaning (14) and process water treatment (16), 1.2.1. In this case, the Kokstrenner (13) has a cooling jacket, which is charged with cooling water (KW), wherein a line emanating from the cooling jacket leads the heated water in the coke cleaning (14) and 1.2.2. In addition, the Kokstrenner (13) has a further material lock (15), through which the washed coke (K) can be removed, 1.2.3. a from the coke cleaning (14) outgoing water line leads to the process water treatment (16), in which the process water from the coke cleaning (14) and the gas scrubbing (19 to 23) using the waste heat from the combined heat and power plant (18) in distilled water (dW) and Fertilizer salts (D) are separated, 1.2.4. Finally, a gas line (G) from the Kokstrenner (13) for gas treatment (19 to 22), 1.3. the gas treatment (19 to 24) from the coolers (19 to 21), a distillation (22), an oil separator (23), an oil dryer (24) and the clean gas reservoir (25), 1.3.1. in the coolers (19 to 21) with a cooling temperature of radiator 1 (19) 200 ° C, radiator 2 (20) 120 ° C and finally radiator 3 (21) to 30 ° C, the exhaust gas (G) from the Kokstrenner ( 13) are gradually cooled, whereby crude oil is separated from the gas, 1.3.2. from the coolers (19 to 21) lead crude oil lines in the still (22), in which by means of the exhaust gas of the heating mantle (12) from the coke reactor (11) the crude oil in tar (T) and fuel oil can be separated 1.3.3. a second line leads from the oil separator (23) to wastewater treatment (17), 1.4. Finally, the plant is assigned as energy converter a cogeneration plant (18), which converts the purified exhaust gases and heating oils in electrical energy and process heat.
