Description
Technical field
This method belongs to field of waste incineration, and in particular to a kind of old oxygen-enriched high temperature intelligent control combustion stability of rubbish
Method.
Technical background
In view of sanitary landfill method has, Technical comparing is ripe, operational administrative is simple, treating capacity is big, invest and operating cost compared with
The advantages that low, suitable for all types rubbish, and China's most important Treatment Way of Municipal Refuse in City at present.But with when
Between passage, there is the antiseepage of field bottom, percolate processing, the recycling of landfill gas, landfill in the increase of Municipal Garbage Yield
The outstanding problems such as area preciousness increasingly.Therefore the improvement demand to old rubbish is imperative, and these old rubbish generally press thing
Combustible by refuse classification, is used for burning electricity generation by material using classification after classification, by fertile soil for cultivating urban landscape vegetation,
Brick and tile class rubbish is used for brickmaking after processing.
Based on above-mentioned background, it is now desired to can make old rubbish can be with particular for the low old waste incinerator of calorific value
Fully burning and thoroughly decomposition, avoid the discharge of bioxin in incinerator.
The content of the invention
The present invention proposes a kind of method of the old oxygen-enriched high temperature intelligent control combustion stability of rubbish, and particular content is：
A kind of method of the oxygen-enriched high temperature intelligent control combustion stability of old rubbish, including grate incinerator and oxygen-enriched combusting system
System, wherein, oxygen-enriched combustion system includes burner, auxiliary fuel feeding mechanism, apparatus of oxygen supply, igniter fuel feeding mechanism group
Into its specific method and step is：
Oxygen-enriched combustion system by the auxiliary fuel in auxiliary fuel feeding mechanism in burner after ignition, into stove
Arrange in incinerator, play a part of fired state in stable stove；
Old rubbish is sent into grate incinerator, in the presence of oxygen-enriched combustion system, old rubbish is successively through overdrying
Residue discharge grate incinerator is converted into after dry, burning, after-flame three phases.
High-efficiency cleaning burning is carried out to the old rubbish of low heat value using the above method and then its energy is utilized, both
Pollution of the old rubbish to environment and soil can be reduced, and can makes old rubbish " turning waste into wealth ".
Further technical scheme is：Auxiliary fuel is sent into burner by auxiliary fuel feeding mechanism；Igniter fuel
Igniter fuel is sent into burner by feeding mechanism；Apparatus of oxygen supply is divided into two branch roads and enters gaseous oxygen pneumatic transmission in burner, gas
State oxygen part supply auxiliary combustion, gaseous state oxygen another part supply igniter fuel.
Using the above method, igniter fuel and auxiliary fuel are provided for burner, and makes them all in burner internal point
Combustion, burning degree are easier to control, and burning is also more stable in burner, and the burning in grate incinerator is also more stable.
Further technical scheme is：Auxiliary fuel ignition in burner is reached by following method and step
State：
Fully premix forms high temp fire core to a part of gaseous state oxygen in the burner with igniter fuel；
Fully premix forms oxidizing combustible to another part gaseous state oxygen in the burner with auxiliary fuel；
Ignited oxidizing combustible by high temp fire core, make oxidizing combustible ignition in burner, oxidizing combustible is burning
Into in grate incinerator, so as to stablize fired state in stove.
Using the above method, to adding oxygen in igniter fuel and auxiliary fuel, reduce their ignition temperature, burn
Reaction speed is accelerated, ignition temperature improves.
Further technical scheme is：Grate incinerator carries out the online Comprehensive Control that links with oxygen-enriched combustion system,
Regulate and control fuel flame temperature, intensity, eddy flow degree and the fire type size in burner, improve the temperature in grate incinerator, increase
Disturbance in strong stove, extend flue gas in residing time in furnace, realize the high-efficiency cleaning burning of old rubbish, its specific method step
Suddenly it is：
A, according to First air air volume signal and Secondary Air air volume signal detection grate incinerator in gas turbulence intensity or
Flue gas carries out feedback regulation in residing time in furnace, until the turbulence intensity of gas is up to standard or flue gas is more than in residing time in furnace
Equal to 2s, step b is carried out；
B, the size of 850 DEG C of grate incinerator temperature and normal temperature is contrasted according to grate incinerator temperature signal：Work as stove
When row burns furnace temperature >=850 DEG C, step c is carried out；As 850 DEG C of grate incinerator temperature ＜, oxygen-enriched combustion system is put into, is returned
Step a；
C, oxygen content of smoke gas is drawn according to oxygen content of smoke gas signal, contrasts oxygen content of smoke gas and standard fume oxygen content 6%
Size：When oxygen content of smoke gas >=6%, illustrate that burning state is normal, after certain interval of time, recirculate whole step；
As oxygen content of smoke gas ＜ 6%, increase the air force of primary air fan and overfire air fan, return to step a.
Using the above method, it is possible to reduce the generation of bioxin, make emission compliance.
The beneficial effects of the invention are as follows：
(1) waste incineration low-cost high-efficiency.Based on the technical of conventional garbage burning electricity generation technology, old rubbish is utilized
Oxygen-enriched high temperature intelligent control combustion stability technical finesse landfill yard rubbish is to realize " minimizing, recycling, rapid " optimal way
Footpath.For the characteristic that the old refuse thermal value of landfill yard is low, composition mixes, unit weight is larger, recovery technique must use inexpensive, low
Energy consumption, pollution-free, high efficiency industrial circuits.Using existing waste incineration and generating electricity mature technology and experience, using old rubbish
Oxygen-enriched high temperature intelligent control combustion stability technology, make up landfill waste burn property difference the shortcomings that.
(2) it is thorough to repair degree.Rubbish is after even if sanitary filling field is by closing, it is still desirable to which lasting carry out is follow-up
Management and disposal.The timely disposal of old rubbish can be realized using this technology, by landfill yard rubbish in a manner of fuel, auxiliary
The optimization of high-efficiency cleaning combustion system, realize that the old high temperature garbage of landfill yard overdoes burning, effectively handles old rubbish, realizes rubbish
The quick of rubbish landfill yard place is thoroughly repaired.
(3) secondary pollution is small.The processing of accessory substance is using existing in the gas and residue discharged after high-efficiency cleaning burning
Mature technology is disposed in real time with equipment, effectively controls pollution risk.Landfill yard seepage head's phase can be effectively avoided to underground simultaneously
The potential threat of water, surface water and ambient atmosphere environment.
(4) project land used saves.Industrial equipment uses efficiency comes first principle, and principle is built in refuse landfill, is not take up
Town site, the situation being becoming tight in face of land resource day, effectively solution landfill method floor space is big, heavy-polluted to ask
Topic.
(5) " neighbour keeps away " risk is small.This programme is proposed in the range of refuse landfill place, is built according to landfill yard actual state
If landfill yard junk-free burns station, the risk that the masses resist strongly by project site selection, operation etc. can be effectively reduced, while can be big
The big environmental risk reduced in landfill waste cost of transportation and transportation.
