Description
Technical field
The present invention relates to garbage harmless, minimizing distributing disposal field more particularly to a kind of small-sized house refuses to burn
Burn the wind-distributing pipe of furnace.
Background technique
The rural area in the area such as scarcely populated mountain area, grassland, desert is come, the average daily yield of house refuse is little, difficult
To concentrate on a large scale, be not suitable for centrally disposing mode using the house refuse of the current large- and-medium size cities in China.Using small-sized rubbish
Incinerator carries out the distributing disposition of adaptation to local conditions, achievees the purpose that the minimizing, innoxious of house refuse, is relatively good choosing
It selects.
The burning process of house refuse can generally pass through two stages that obviously do not demarcate, and first stage is volatile matter
Combustion phases, namely the stage is just burnt, at this stage, rubbish can be heated, heat up, ignition, some group branches gasify because of heating,
It generates fuel gas and burns, some components can then be carbonized, and form carbon residue, the noxious pollutant which generates is mainly ingredient
The substances such as extremely complex VOCs, PM, wherein VOCs is in the majority with various HC, or even including the longer HC of strand, the stage is anti-
Answer process rapid and not easy to control, oxygen demand is also more；Second stage is the stage of carbon residue burning, namely deep burning stage, is somebody's turn to do
The reaction speed in stage is relatively slow, and generating noxious pollutant is mainly the lesser gaseous material of the molecules such as CO.Incinerator outlet
Noxious pollutant in flue gas is mainly from the first stage.
In general, either small refuse incinerator or bulky refuse incinerator, burn the life rubbish of unit mass
The theoretical air consumption of rubbish can rule of thumb or test obtains, in order to guarantee that burning effect, practical air demand must be than reasons
It is more by air consumption.But for small incinerator, since to enter stokehold not preprocessed for rubbish, into incinerator after difference portion
There are huge differences for the rubbish distribution of position, in order to guarantee that burning state of the rubbish in furnace achieves the desired results, often
Take the excessive gas supply coefficient more much bigger than large-scale incinerator.It is excessive to supply coefficient generally on 1.7 left sides by taking large-scale grate furnace as an example
The right side, and the excess air coefficient of small refuse incinerator is sometimes even over 3.0, it is meant that nearly 2/3rds enter stove air
It is practically without participation and burns just discharge burner hearth, will cause several respects counter productive in this way, firstly, the incineration firing of certain mass
The heat of generation is limited, and a large amount of normal temperature air namely cold air are sent into burner hearth, and fire box temperature can be made to be difficult to reach pre-
The height of phase, if fire box temperature is too low, harmful pollutants in flue gas, such as bioxin cannot utilize hot environment point
Solution, great difficulty will be brought to after-treatment system, especially for the higher low heat value house refuse of moisture content, will more be encrypted
It is real, it is easy agglomeration, air is not easy to contact with duration and degree of heating, needs that bigger excessive gas supply coefficient is taken just to can guarantee that rubbish maintains combustion
It burns, such furnace temperature is lower, and fume treatment difficulty is bigger；Secondly, smoke yields and feed burner hearth air capacity be it is positively related,
In the case that quantity of refuse is set, excessive gas supply coefficient is bigger, and exhaust gas volumn is more, and the load of after-treatment system is bigger, investment and fortune
Row cost is higher；Again, the main air blower energy consumption of air demand and incineration system is also positively related, and the excessive coefficient that supplies is bigger, main
Fan energy consumption is accordingly higher, and the operating cost of incineration system also can be higher, namely increases the joint disposal cost of rubbish.
Can in fact, small refuse incinerator supply mix burn air often from the bottom up first seepage flow through too deep burning rubbish
Layer, then waste layer is just burnt to entering, due to waste component, the complexity of state, even if excessive gas supply coefficient is big again, it is also difficult to protect
Each duration and degree of heating position that card just burns waste layer can adequately be supplied oxygen.So mixing burning during how organizing incineration firing
