Detailed description of the invention
Below by detailed description of the invention, the utility model is described in detail.
Combustion control device in a kind of incineration treatment of garbage, flue 6 between the exhanst gas outlet 5 and air-introduced machine 7 of the second combustion chamber 17 set by incinerator is provided with lambda sensor 10, the content of oxygen in flue gas is detected by this lambda sensor 10, according to the norm controlling air feed of this gas content, it is 5 ~ 13% that the oxygen content that control air feed makes lambda sensor 10 detect remains on volume fraction.It is the scope internal control making blower fan 7 of-1000 ~-100 handkerchiefs in negative pressure value simultaneously.
Described incinerator comprises body of heater 1, and the top of this body of heater 1 side is provided with dog-house 2; Be arranged with the first combustion chamber 16 and the second combustion chamber 17 by furnace wall 3 in body of heater 1, wherein the first combustion chamber 16 is positioned at the side of the second combustion chamber 17; First combustion chamber 16 is connected by set cinder chamber 4 with the bottom of the second combustion chamber 17; The top of the second combustion chamber 17 is provided with exhanst gas outlet 5, and this exhanst gas outlet 5 is connected with air-introduced machine 7 by flue 6.
The front end of described body of heater 1 is respectively equipped with the air door 8 of an air feed and the air door 9 of secondary air feed; First combustion chamber 16 is divided into the up-down structure in combustion zone, top and lower combustion district by upper fire-grating 12 and lower fire grating 13; Be spaced apart 10 ~ 12cm between the adjacent fire grate segment of described upper fire-grating 12, between the adjacent fire grate segment of lower fire grating 13, be spaced apart 2 ~ 3cm.The air door 8 of a described air feed is arranged with two, is all positioned at the top of upper fire-grating 12; The air door 9 of secondary air feed is arranged with two, all between upper fire-grating 12 and lower fire grating 13.The top of described lower fire grating 13 is arranged with two breast holes 18, and this breast hole 18 is positioned at below the air door 9 of secondary air feed.The such design in described first combustion chamber 16 makes rubbish obtain thoroughly effective burning.The bottom of the first combustion chamber 16 is designed to main combustion zone, make the high-temperature flue gas of main combustion zone can upwards radiation, heat the rubbish in the first top, combustion chamber 16 and air inlet, thus again can play the effect that heating supplies wind action and accelerated combustion, and flue gas trend is downward, gives rubbish and burns the time fully.
Described furnace wall 3 is heat conducting wall, and heat conducting wall is the heat-conduction wall that high-alumina brick or silicon carbide material are made.Rely on the heat conductivility of furnace wall 3, heat the air of the first combustion chamber 16 and furnace charge and rubbish.The heat part of the second combustion chamber 17 reaches the first combustion chamber 16.Such as use common high-alumina brick, when the second combustion chamber 17 record temperature reach 1000 DEG C time, be then delivered to the temperature of the first combustion chamber 16 at 300 ~ 400 DEG C, directly improve fire box temperature, dioxin and other pollutants are more thoroughly decomposed.
The room Kou Chu that described cinder chamber 4 is positioned at body of heater 1 front end is provided with and locks a door 11.
The top of described first combustion chamber 16 is provided with lime charging aperture 14, and this lime charging aperture 14 connects lime bin 15 by feed pipe.Like this while rubbish is burned, also depickling is carried out to produced flue gas, shortened treatment cycle.
The first combustion chamber 16 is sent into by the dog-house 2 of body of heater 1 one upper lateral part by needing rubbish to be processed, rubbish first burns at the upper fire-grating 12 of the first combustion chamber 16, then lime-ash drops down onto lower fire grating 13 and proceeds burning, due to the effect of outside air-introduced machine 7, the second combustion chamber 17 in incinerator is made to produce negative pressure, like this by twice air feed that the air door 8 of an air feed and the air door 9 of secondary air feed enter, with be run downwards in the first combustion chamber 16 communicated bottom the second combustion chamber 17, form anti-burning, substantially increase the burning degree of rubbish; A part of heat is passed to the first combustion chamber 16 by heat-conduction wall by the high temperature that meanwhile the second combustion chamber 17 produces, and the fire box temperature directly improved, makes dioxin and other pollutants more thoroughly decompose.Simultaneously on one end near chimney of flue 6, be provided with lambda sensor 10 or carbon monoxide transducer; like this can oxygen content or carbon monoxide content in Real-Time Monitoring flue gas; thus control air feed and feed; and lambda sensor or carbon monoxide transducer are located at this position can protect sensor not damage by the too high flue gas of temperature; extend its service life, reasonable in design.
