Background technology
Incinerator comprises primary zone and dual firing chamber.Primary zone is the burner that is mainly used in burning life, medical waste, and the harmful substance not burning in flue gas is further destroyed by dual firing chamber, makes not burn material and thoroughly decomposes, and reaches emission request.And traditional dual firing chamber is because furnace cavity is limited, there is the phenomenon of severe depletion of oxygen in burner hearth central area, causes secondary flue gas fully not burn just by heat-exchanging chamber, from smoke stack emission, to fall, and not only produces black smoke, wastes energy, again contaminated environment.Also there is configuration secondary air feed system in current dual firing chamber, and hope can realize flue gas and further burn, and still inhomogeneous but Secondary Air distributes, combustion efficiency is not ideal enough.
Summary of the invention
Goal of the invention of the present utility model is to have above-mentioned deficiency in order to overcome prior art, and a kind of incinerator dual firing chamber with air supply device is provided, and realize the Secondary Air uniform distribution that enters dual firing chamber, flue gas can thoroughly be burnt, can not produce the pernicious gases such as bioxin, not only energy-conservation but also environmental protection.
The technical solution of the utility model is: top cover is equipped with in body of heater upper end, and air supply device is equipped with in top cover upper end; Described air supply device comprises Secondary Air balanced device, two above Secondary Air pipelines that are connected with Secondary Air balanced device, described Secondary Air balanced device is a housing, housing upper end has air intake vent, under housing, end periphery has two above connecting holes, each Secondary Air pipeline one end is loaded on each connection hole, each Secondary Air pipeline other end and body of heater intracavity inter-connection.
Described housing is truncated cone-shaped, comprise little head end, with the stub end that little head end is connected, on little head end, have air intake vent, stub end periphery has two above connecting holes.
Described each connecting hole is uniformly distributed in stub end periphery.
Described air intake vent place is connected to air blast.
Described each Secondary Air pipeline one end is connected with each connecting hole through flange one; Described top cover is provided with two above connecting pipes corresponding with each pipeline other end, and each Secondary Air pipeline other end is connected with connecting pipe 4 through flange two.
Described top cover is provided with support member, and Secondary Air balanced device is loaded on top cover through support member.
Described top cover is loaded on body of heater through flange three.
Described body of heater is provided with fire brick layer, is positioned at the lightweight heat-proof cast bed of material outside fire brick layer.
Described top cover, Secondary Air balanced device, Secondary Air pipeline, connecting pipe, support member are provided with lightweight heat-proof castable and castable refractory.
Described bottom of furnace body is provided with an above cinder-discharging port, and each cinder-discharging port place all connects a lock wind batcher, under each lock wind batcher, all connects a grey trolley.
The beneficial effects of the utility model are: according to the wind supply quantity size of Secondary Air, adopt the regulation and control of Secondary Air balanced device, some Secondary Air pipelines are evenly shunted to air feed, flue gas is mixed in dual firing chamber more even with Secondary Air, realizing flue gas can thoroughly burn, and can not produce the pernicious gases such as bioxin.
The specific embodiment
In Fig. 1,2,3, the utility model comprises 2,16 Secondary Air pipelines 3 of Secondary Air balanced device and top cover 5 and body of heater 6.Wherein, Secondary Air balanced device 2 is a truncated cone-shaped housing, and its upper end bore is little, and lower end bore is large, and upper end is provided with air intake vent 1, the external post-blast machine of air intake vent 1.Each Secondary Air pipeline 3 is arc bend cast, and each Secondary Air pipeline 3 is evenly distributed on same circumference.Each Secondary Air pipeline 3 one end connect and link together with lower port through flange one.Several connecting pipes 4 that are welded with on top cover 5, Secondary Air pipeline 3 other ends and connecting pipe 4 are connected together in succession through flange bigeminy, and its effect is according to intake size, regulates secondary wind wind speed, makes Secondary Air evenly enter each Secondary Air pipeline 3.
Body of heater 6 connects with top cover 5 and links together through flange three.Body of heater 6 upper left quarters are provided with for entering and once burn the gas approach 14 producing, and right lower quadrant is provided with the exhanst gas outlet 7 producing for discharging secondary burning.Body of heater 6 bottoms are provided with some cinder-discharging ports 8, and each cinder-discharging port 8 all connects one for controlling the lock wind batcher 11 that unloads grey speed.Each lock wind batcher all connects one for collecting the grey trolley 9 of flying dust.Body of heater 6 is supported by some supports 10, and whole incinerator is fixed on ground via some supports 10 by foundation bolt.Body of heater 6 inwalls first apply one deck lightweight heat-proof castable 12, then apply one deck refractory brick 13.Top cover 5 housings, Secondary Air pipeline 2 and connecting pipe 4 form by lightweight heat-proof castable 12 and castable refractory cast.
