Specific embodiment
As shown in Figure 1, 2, a kind of secondary air type waste incinerator of the present invention, main body include furnace body and combustion chamber, burning
Room is located in furnace body, and combustion chamber includes primary zone 1 and secondary combustion chamber 2；Primary zone 1 is arranged in entire furnace body
Lower part, the center position that bottom is bored under primary zone are provided with fire bars 15, and fire bars 15 is placed on drop-bottom 16；Inspection socket 6
Up to stretching out except furnace body since the edge that fire bars carries on the back parallel one end, and mouthful hermatic door 26. is looked into equipped with picking up
Secondary air-inlet channel 3 and feed inlet 5 of the present invention are arranged at the middle part of entire furnace body, and the two is arranged in parallel；Feed inlet connection
Combustion chamber point takes fore shaft to handle, and the space except fore shaft is secondary air-inlet channel, and ring is had mercy on entire fore shaft surrounding, outside feed inlet
Sealed feed inlet external door 25 is set.The side up and down direction in air duct is arranged in trumpet type in air inlet 10, and oral area is according to being matched
The bore of blowing device, pressure fan or air blower consistent square or round, and with used in flange aperture connection.In the middle part of combustion chamber
It faces setting air pushing hole 23 on plate 32 directly, conical surface air inlet hole 24, air pushing hole 23 and air inlet hole is set on cone plate 33 in the middle part of combustion chamber
24 be that air duct is blown the necessary port of oxygen supply into burner hearth, and air inlet hole is distributed along surrounding uniform crossover.
Dual firing chamber shown in II is arranged in the top of furnace main body in figure, 4 in the figure that dual firing chamber is configured shown in dual firing chamber
Flue portion is in dual firing chamber's top ring and haves mercy on entire inner cavity surrounding, faces directly in inner cavity and is provided in figure dual firing chamber's flue gas shown in 8 and goes out
Mouthful.
Secondary combustion chamber 2 of the invention is arranged on the top of entire furnace body；Secondary combustion chamber flue 4 is set to secondary combustion
Ceiling portion is burnt, around entire inner circle surrounding；Inner periphery faces plate directly and is provided with dual firing chamber's exhanst gas outlet 8；Smoke outlet tube connects 7 and two
Secondary combustion chamber flue is connected to and stretches out furnace body.Secondary combustion room exhanst gas outlet is since buffler first outlet, descending rule
Then be distributed, until smoke outlet tube connects direction, flue gas trend since the mouth of buffler side the above rotation situation to exhanst gas outlet
Pipe connects flowing, and entire flue gas tumbling motion in thorax increases flue gas in the residence time of internal high temperature period, bulky grain flue dust and
Its heavy metal particles object can return to combustion chambers burn while tumbling motion continuous with flue gas.In the premise of secondary oxygen supply
Under, flue gas can more fully burn after entering dual firing chamber, so that the flue-gas temperature of dual firing chamber is higher than chamber temperature, have
Effect ground decomposes and destroys bioxin synthetic.Better treatment conditions are created for the process flow of rear portion smoke processing system.
Furnace body of the present invention is made of outside plate 11 and inner panel 12, is provided with to be poured by castable between outside plate and inner panel and is formed
High temperature resistance protective layer.It with the setting of multistage setback formula, is welded from top to bottom by multistage face inner core steel plate 14 the intracorporal combustion chamber of furnace
It is connected into an intercommunication entirety；Inner Wall of Combustion Chamber, which is provided with, is poured the high temperature resistance protective layer formed by castable 18.Secondary combustion chamber
Flue is made of the space between outside plate I 19, inner panel I 20, cover board 13 and the outer wall of secondary combustion chamber；It is set between outside plate and inner panel
It is equipped with the high temperature resistance protective layer for being poured and being formed by castable.There are one between insulating layer of furnace body and high temperature resistance protective layer of the invention
Space is determined, i.e. partition space 22, to prevent kernel thermal energy from dissipating head along solid.The orphan of cover board 13, secondary combustion chamber of the invention
Top plate 27 constitutes furnace body top surface, and outside plate I, cover board, outside plate constitute outer surface, and drop-bottom constitutes furnace body bottom surface.
The present invention is welded with cover board 9, cover board and dual firing chamber's flue on the furnace body of 34 bottom of upper cone-plate of secondary combustion chamber
Gusset 28 is reinforced in setting between insulating layer outside plate, and drop-bottom faces part directly beyond furnace body and is also equipped with reinforcing gusset 28.The present invention exists
Insulating layer is set between secondary combustion room and furnace body and separates space 21, prevents heat energy dissipation.
Secondary air-inlet channel location of air supply inlet of the present invention is necessarily placed at the side of body exterior, is again in addition forced air supply,
In order to change the direct stress for entering air duct air-flow, it has been welded in internal furnace Board position corresponding with air inlet and has shunted buting iron 31, prevented
Infinitely great reflux only is generated with shown charging sidewall panel in inlet air flow impact figure, the air capacity for causing each air pushing hole to enter
Unevenly, burning effect is influenced.
In order to promote flue gas tumbling motion in burner hearth, allow high-temperature flue gas can in thorax the residence time it is a little longer, two
Smoke-box buffler 30 is arranged in smoke outlet tube and connects useful space position between 7 and maximum outlet flue, entire facade space
All shut.Because dual firing chamber's exhanst gas outlet 8 is the descending distribution in proportion since buffler side, maximum outlet flue is cigarette
Gas exports shock point, other each exiting flue gas along flue under the action of flow of flue gas power with transverse compression cyclone mode from figure
Middle smoke outlet tube connects the export of 7 directions.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But without departing from the technical solutions of the present invention, according to the technical essence of the invention to above embodiments institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection scope of technical solution of the present invention.
