Embodiment 1
[0045] After the garbage is sorted by the sorting device, 50% of plastics, 5% of wood chips and paper, 45% of biological and kitchen waste, and a moisture content of 35%. After extrusion, dehydration, granulation and drying, the moisture content is reduced to 20%. density≤3cm, 1.0mm river sand is added to the gasifier from the bed material hopper, 0.8mm dolomite is added according to dolomite:garbage=0.3:1 (kg / kg), the operating temperature of the gasifier is 650°C, and the inner flow of the furnace is controlled The melting speed is 3.5m / s, the melting chamber temperature is 950°C, the steam pressure generated in the melting chamber is 0.75MPa, and the dioxin content in the gas is 0.008ng / Nm3. The high-temperature gas generated by the gasifier and the high-temperature flue gas generated by the melting chamber are sent to the coal-fired boiler for coupling power generation. The temperature of the steam extracted from the steam power generation device is 250°C, and the dioxin co...
Embodiment 2
[0047] After the garbage is sorted by the sorting device, 70% of plastics, 5% of wood chips and paper, 25% of biological and kitchen waste, and a moisture content of 20%. After extrusion, dehydration, granulation and drying, the moisture content is reduced to 9%. Density ≤ 3cm, 0.9mm river sand is added to the gasifier from the bed material hopper, 0.6mm limestone is added according to limestone:garbage=0.6:1 (kg / kg), the operating temperature of the gasifier is 850°C, and the fluidization speed in the furnace is controlled 3.0m / s, the melting chamber temperature is 900°C, the steam pressure generated in the melting chamber is 0.5MPa, and the dioxin content in the gas is 0.01ng / Nm3. The high-temperature gas generated by the gasification furnace and the high-temperature flue gas generated by the melting chamber are sent to the coal-fired boiler for coupled power generation. The slag is sent to building material processing plants or landfills.
Embodiment 3
[0049] After the garbage is sorted by the sorting device, 25% of plastics, 15% of wood chips and paper, 60% of biological and kitchen waste, and a moisture content of 50%. Density ≤ 3cm, 1.5mm river sand is added to the gasifier from the bed material hopper, 1.0mm calcium oxide particles are added according to calcium oxide particles: garbage = 0.2: 1 (kg / kg), the operating temperature of the gasifier is 600°C, and the furnace is controlled The internal fluidization velocity is 3.0m / s, the melting chamber temperature is 1150°C, the steam pressure generated in the melting chamber is 1.0MPa, and the dioxin content in the gas is 0.007ng / Nm3. The high-temperature gas generated by the gasification furnace and the high-temperature flue gas generated by the melting chamber are sent to the coal-fired boiler for coupling power generation. The slag is sent to building material processing plants or landfills.
