Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
Embodiment 1: a kind of heterogeneous vertical high-temperature suspension combustion innoxious burning boiler, comprise fuel feed system, high-temperature incinerator 18 and residual neat recovering system, described high-temperature incinerator 18 comprises secondary air system 4, and described fuel feed system comprises waste gas feed system 2, waste liquid feed system 3 and the wastewater feed system 5 that layering is arranged; Secondary air system 4 is provided with between described waste liquid feed system 3 and wastewater feed system 5; Described residual neat recovering system comprises water-cooling system 7 and the high-temperature air preheater 10 connected successively, middle warm air preheater 11, economizer 12, low-temperature air preheater 13, and wherein said water-cooling system 7, high-temperature air preheater 10, middle warm air preheater 11, economizer 12, low-temperature air preheater 13 are installed on steelframe 8.
Embodiment 2: described waste gas feed system 2 includes calorific value exhaust gas inlet 15, without calorific value exhaust gas inlet 16 and biogas import 1.Described wastewater feed system 5 is provided with Waste liquid atomization shower nozzle, and described Waste liquid atomization shower nozzle is positioned at secondary air system side, and wherein secondary air system 4 adopts and arranges in the other direction.Described high-temperature incinerator 18 is provided with temperature point 17, and exit is provided with soot blower 9.The nozzle of secondary air system 4 and the angle of central axis are 5 ~ 15 °.Remainder is identical with embodiment 1.
In conjunction with above-described embodiment, the utility model in use, the layering of multiply waste gas enters high-temperature incinerator 18 burner hearth from the bottom of waste gas feed system 2, and carry out sufficient mixed combustion with suitable flow velocity and combustion-supporting gas (biogas) and waste water, waste liquid, form tangential firing, air-flow changes circular motion into by tangential motion from bottom to top.The overwhelming majority of swirling eddy is run along on inboard wall of burner hearth screw, form gas, solid thermo-molecular collides mutually, and realize gas and rise in the shape of a spiral, forming desirable combustion field makes the burning of gaseous combustible thing and oxygen more abundant, ignition temperature can reach about 1100 DEG C, waste liquid and the compressed air of joining enter from the bottom of high-temperature incinerator 18, waste water point multilayer sprays into from the middle and upper part of high-temperature incinerator 18 in atomization shape, run into high-temperature flue gas to carry out evaporating, decompose and burning, thus achieve the high temperature suspension combustion of heterogeneous air-flow.
