But will increase a large amount of loads simultaneously, or reduce waste incineration amount etc., that is, sacrifice other members and usually reach standard.
Summary of the invention
Purpose of the utility model is to solve carbon monoxide in circulating fluidized bed incinerator to be unable to fully asking for burning
Topic, provides a kind of incinerator primary air arragement construction for suppressing or eliminating carbon monoxide.
Above technical problems of the utility model are mainly solved by the following technical scheme: a kind of inhibit or disappear
Except the incinerator primary air arragement construction of carbon monoxide, the First air including being connected to incinerator lower part gives combustion cylinder, it is characterized in that
Separately branch is connected with interception valves on the inside of the output end lighting valve that the First air gives combustion cylinder, is connected by interception valves and intercepts pipe
Penetrate the incinerator below first level flue, and be arranged one group and be located at the nozzle for intercepting tube end, and nozzle inclination to
30 ± 2 degree lower, the nozzle is fixed in incinerator on the fin between water-cooling wall；One group of nozzle forms one of air curtain.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, the nozzle
Arrange that width is greater than first level flue outlet flue overall width.Comprehensive interception, full combustion.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, the nozzle
Outlet is flushed with water cooling wall surface.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, one group of spray
Unrounded number is 20~40.It is installed in the form of comb, is uniformly supplied oxygen.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, the First air
The lighting valve and interception valves for giving combustion cylinder output end are chain or interlock switch.When lighting valve work, interception valves are closed, and are worked as and burnt
When burning furnace normal work, lighting valve is closed, and interception valves are opened.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, the nozzle position
Below the first level flue at 1.2~1.5 meters.Since carbon monoxide rises to first level flue outlet position flow velocity most
Fastly, interception effect is not good enough, and being located at design size position is best interception region.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, the spray nozzle part
Equipped with check valve.
In the incinerator primary air arragement construction above-mentioned for suppressing or eliminating carbon monoxide, preferably, the nozzle has
There are loudspeaker ejiction opening or flat divergence form ejiction opening.Uniformly intercept region combustion space.
The technical program, which be wanted to protrude in cheap, effect in simple, cost from structure etc., to be accounted for designing.
Circulating fluidized bed incinerator top is suspension combustion mode, and lower part is grate firing type combustion system, is burnt in recirculating fluidized bed rubbish
It burns furnace the main reason for generating a large amount of carbon monoxide and is because the water content in rubbish is larger and unstability, it is often different
The detonation of degree and generate positive pressure and carbon monoxide caused largely to generate.These carbon monoxide that whatsoever mode generates are finally all
It will be pooled to first level flue, i.e., exported by the passageway of burner hearth to material returning device, that is to say, that near first level flue
It is carbonomonoxide concentration highest position.This programme utilizes primary air fan (giving combustion cylinder equipped with First air), tool according to this phenomenon
Have high pressure, compared with strong penetrating power the features such as, attempt highest point in carbon monoxide and intercepted, not only effective prolonging burning time, and
And change furnace air dynamic regime, so that the carbon monoxide of circulating sulfuration bed garbage furnace be effectively reduced, reach discharge mark
It is quasi-.
Further, interception valves are arranged on the inside of the output end lighting valve that First air gives combustion cylinder in this programme, pass through interception valves control
System intercepts pipe, intercepts pipe and penetrates incinerator below first level flue and utilize the fin fixed nozzle between water-cooling wall, nothing
Any auxiliary need to be increased.Nozzle inclination is installed downwards, is allowed to oliquely downward spray, to form one of air curtain, effectively be intercepted.
Tradition, prior art circulating fluidized bed incinerator application, people often from allow by combustion things adapt to boiler carry out
Effect design is such as first handled burned rubbish, and the technical program is " allowing boiler to adapt to by combustion things matter ", to extend
Burning time makes combustible further be fully burned in best " at focusing ", to reduce discharge.
The beneficial effects of the utility model are: the design for intercepting pipe nozzle plays the role of furnace arch, furnace nose, delay significantly
Flue gas flow rate, prolonging burning time are mixed with the air quantity of high-pressure blast in high-temperature area, are allowed to full combustion；Arranged type arranges shape
Formula keeps high-pressure blast evenly distributed, when flue gas passes through, such as comb combing, achievees the purpose that be uniformly mixed to combustion gas body；It utilizes
The surplus of primary air fan does not need to add any ancillary equipment, at low cost；The property of primary air fan is changed, it further, can be same
The original so-called First air of successive step, Secondary Air, when bed pressure is higher, combustion-supporting to penetrate wind sendout also bigger；Because of catching portion
Point penetrate wind in First air, and it is practical used as Secondary Air, therefore can be used and turn down secondary air flow, guaranteeing always
In the constant situation of oxygen amount, secondary wind pressure is further increased, the penetration power of Secondary Air is further strengthened, is conducive to full combustion.
