The utility model has been realized the liquid and solid-state hazardous waste grate furnace incinerator of charging respectively, having solved grate furnace incinerator can only combustion of fossil fuels (as coal) and the problem of solid waste (as house refuse), realized the innoxious and energy recycling of hazardous waste, liquid hazardous waste feed arrangement and solid-state hazardous waste feed arrangement can be distinguished isolated operation, the liquid hazardous waste of low heat value cannot also can move during independent burning simultaneously, both guaranteed the grate furnace stable operation of putting hazardous waste burn system of coexisting, also guaranteed the instant incineration disposal of solid-state and liquid hazardous waste.
Accompanying drawing explanation
Fig. 1 is that hazardous waste burn system structural representation is put in grate furnace coexistence;
In figure, fire grate 1, a multistage air compartment 2, face arch 3, rear arch 4, slag-draining device 5, burner hearth 6, secondary furnace 7, drum 8, water-cooling wall 9, feeding-in solid body mouth 10, liquid inlet opening 11, overfiren air port 12, liquid hazardous waste tank 13, liquid hazardous waste mix batcher 19 to pump 14, liquid hazardous waste spray gun 15, solid-state hazardous waste feed bin 16, solid-state hazardous waste batcher 17, feeder 18, closed.
The specific embodiment
As shown in Figure 1, grate furnace coexistence is put hazardous waste burn system and is comprised grate furnace incinerator body and feed system; Grate furnace incinerator comprises fire grate 1, a multistage air compartment 2, face arch 3, rear arch 4, slag-draining device 5, burner hearth 6, secondary furnace 7, drum 8, water-cooling wall 9, feeding-in solid body mouth 10, liquid inlet opening 11 and overfiren air port 12; Burner hearth 6 top furnace walls are furnished with water-cooling wall 9, burner hearth 6 upper ends are provided with drum 8, and drum 8 is connected with water-cooling wall 9, and burner hearth 6 tops are connected with secondary furnace 7, burner hearth 6 belows are provided with fire grate 1, fire grate 1 front end is provided with face arch 3, and fire grate 1 rear end is provided with rear arch 4, and face arch 3 is respectively equipped with liquid inlet opening 11, feeding-in solid body mouth 10 up and down, fire grate 1 below is provided with a multistage air compartment 2, burner hearth 6 both sides are provided with overfiren air port 12, and are positioned at liquid inlet opening 11 tops, and fire grate 1 afterbody is provided with slag-draining device 5; Feed system comprises that liquid hazardous waste tank 13, liquid hazardous waste mix batcher 19 to pump 14, liquid hazardous waste spray gun 15, solid-state hazardous waste feed bin 16, solid-state hazardous waste batcher 17, feeder 18, closed; Liquid hazardous waste tank 13, liquid hazardous waste are connected in turn to pump 14, liquid hazardous waste spray gun 15, liquid inlet opening 11, solid-state hazardous waste batcher 17 mixes batcher 19 by closed respectively with feeder 18 and is connected with feeding-in solid body mouth 10, and solid-state hazardous waste batcher 17 is connected with solid-state hazardous waste feed bin 16.
