Description
Technical field
The utility model relates to sludge incineration technical field, specially a kind of sludge incineration furnace structure.
Background technique
As the improvement of people's living standards, large quantities of sewage treatment plants start to build and go into operation in succession.The sewage in China
Generally existing " sewage treatment again, the light sludge treatment " phenomenon for the treatment of industry, causes a large amount of sludge to be difficult to dispose, seriously affects ring
Border quality, highest attention and attention by society.
The sludge ultimate disposal method of municipal sewage plant is mostly to be sent to refuse landfill to be filled, and has plenty of searching
The air storage of periphery vacant lot, this simple disposal options are not suitable for the needs of urban development.And burning disposal is by sludge
Treat as a kind of solid waste, innoxious, recycling, minimizing processing are carried out as domestic waste.Utilize elder generation
Into combustion technology, contracting is weighed 65% or more by sludge after burning, and toxic organic compound is thoroughly decomposed through high temperature.Ash, slag can carry out
Comprehensive utilization is the preferred mode for handling sludge of sewage treatment plant.
Current sludge incinerator is all made of adiabatic furnace and is burned, and the high-temperature flue gas generated after sludge incineration is extracted
Burner hearth heats other media by heat exchanger（Conventional is water, conduction oil）Carry out heat source comprehensive utilization.Due to not having inside burner hearth
Arrange heating surface, the heat of generation of burning by Absorption of Medium and can not be taken away, and it is excessively high to will lead to fire box temperature.Municipal sludge is done
Nitrogen in base portion point is reacted with the oxygen in air during the burning process, can largely be generated NOx nuisance and be polluted environment.
Fig. 1 is conventional sludge incinerator schematic diagram, and burner hearth absorbs dirty using insulation pattern, inside without any heating surface in figure
The heat that mud burning generates, easily causes burner hearth temperature excessively high.Conventional warm-down method can install spray equipment additional, be reduced by spraying water
Fire box temperature.This measure one carrys out waste water resource, and two, which carry out spray head, easily occurs stopping state and influence spraying effect.
Utility model content
The problem undesirable, at high cost for above-mentioned cooling effect, the utility model provide a kind of sludge incinerator knot
Structure, structure is simple, at low cost, good cooling effect, guarantees combustion efficiency.
Its technical solution is such：A kind of sludge incineration furnace structure comprising adiabatic furnace, the adiabatic furnace lower end
Sludge feed mechanism, bottom ignition device and scum pipe are connected, the adiabatic furnace upper side is high-temperature flue gas outlet, special
Sign is, heat-transfer device is provided in the adiabatic furnace at the high-temperature flue gas outlet, and the heat-transfer device includes thermally conductive
Pipe, described heat conducting pipe one end connect heat-conducting medium inlet tube through the adiabatic furnace side wall, and the heat conducting pipe other end runs through
Heat-conducting medium outlet tube is connected at the top of the adiabatic furnace.
It is further characterized by being disposed with two rows of heat conducting pipes in the adiabatic furnace；
The heat-conducting medium is conduction oil or water, and the heat-conducting medium inlet tube connects outer with the heat-conducting medium outlet tube
Portion's heat-exchanger rig.
After the structure of the utility model, heat-transfer device is arranged in adiabatic furnace to control ignition temperature, by leading
Thermal medium takes away the partial heat of sludge incineration generation, controls temperature in burner hearth in 850-900 degrees centigrade, cooling effect
It is good, it not only can guarantee sludge abundant after-flame in burner hearth, but also the generation of NOx nuisance can be reduced to greatest extent, structure is simple, at
This is low.
Detailed description of the invention
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is the utility model structure diagram；
Fig. 3 is heat-transfer device structural side view.
Specific embodiment
See Fig. 2, shown in Fig. 3, a kind of sludge incineration furnace structure comprising adiabatic furnace 1, the connection of 1 lower end of adiabatic furnace are dirty
Mud feed mechanism 2, bottom ignition device 3 and scum pipe 4, sludge feed mechanism 2 generally use screw(-type) feeder, adiabatic furnace 1
Upper side is high-temperature flue gas outlet 5, is provided with heat-transfer device 6, heat-transfer device 6 in the adiabatic furnace 1 at high-temperature flue gas outlet 5
Including heat conducting pipe 7,7 one end of heat conducting pipe connects heat-conducting medium inlet tube 8 through 1 side wall of adiabatic furnace, and 7 other end of heat conducting pipe runs through
Heat-conducting medium outlet tube 9 is connected at the top of adiabatic furnace 1.Two rows of heat conducting pipes 7 are disposed in adiabatic furnace 1, heat-conducting medium is thermally conductive
Oil or water, heat-conducting medium inlet tube 8 and heat-conducting medium outlet tube 9 connect external heat-exchanging device 10, i.e., after heat-conducting medium is heated
It can be used as heat source and participate in external heat-exchanging realization heat source comprehensive utilization.
