Description
Technical field
The invention belongs to solid waste incineration processing technology field, particularly relate to a kind of stoker fired grate formula refuse gasification and burn
Burning system and synthesis gas straight tube combustor.
Background technology
Existing technology of garbage disposal mainly has burning, sanitary landfills, compost, waste recovery etc..Conventional in garbage disposal
In technology, it is obvious that burning disposal has reduced training, innoxious thoroughly, occupation of land amount is little, and waste heat energy is obtained by, and secondary pollution is few
Etc. advantage, meet the strategic requirement of China's sustainable development.But along with both at home and abroad environmental requirement being improved constantly, how to strengthen
Control to secondary pollution is particularly important.Therefore, refuse pyrolysis gasification burning technology is gradually shifted onto the road of industrial applications
On, primarily now using all kinds of incineration technology especially for domestic rubbish, the industrialization widely of gasification burning technology will
The technological innovation bringing domestic garbage disposal industry is regenerated.
For many years, China's scientific research to the gasification burning technology such as biomass, rubbish, it is in progress a lot of, the base of laboratory
Plinth research is a lot, also has applied research, such as: rotary kiln type, the vertical and destructive gasifying of fluidized bed type or temperature gasification and high melt skill
Art etc..But Technique Popularizing application is upper or there is a definite limitation, raw material type, garbage treatment quantity, secondary pollution control and economical
Benefits etc. are principal elements.
In existing burning process and equipment, fire grate type incinerator is various informative, and its application accounts for whole world waste incineration
More than the 80% of the total market size, wherein has and uses mechanical type backstepping fire grate, forwards fire grate or combined fire grate in body of heater, also adopt
With the fire grate such as chain-plate type and drum-type.
In sum, typical incinerator, it is respectively arranged with himself advantage, but needs solution in the actual application of China
Problem and shortage:
1., for characteristics such as China's house refuse water content height, complicated components, the technology of moving hearth uses, to rubbish
Conveying capacity needs emphasis to consider.
2. being on the increase along with refuse production, sanitary fill such as mountain, garbage treatment quantity must be effectively improved,
Could meeting the market requirement.
3., in the face of strict pollutant emission requirement, secondary pollution controls the key problem being technically need to solve.
4., in order to effectively increase economic efficiency, in rubbish heat treatment process, the organic efficiency of heat needs to improve.Existing
Rubbish heat treatment technics generally use boiler to produce steam to shift steam turbine power generation onto, whole transition heat efficiency losses is relatively big, place
Manage identical quantity of refuse, relatively reduce thermal losses and raising heat exchanger effectiveness just can improve the thermal efficiency.
5. during conventional garbage burns mode and boiler applications, high-temperature dust removal is less or does not has, and some efficiency is the most not high enough, high
It is less that effect dedusting and burning are had both, and the easy dust stratification of boiler makes thermal conversion efficiency decline, thus lower power production, maintenance period is short
Deng.
Existing incinerator such as following two patent of invention: multiple row sectional drive combined type domestic garbage incinerator
(ZL200710092508.9) an open question and in two-stage garbage incinerator (ZL201010268376.2): at rubbish heat
Reason model comparision falls behind, and be simply dried-burns-burns, the process of solid combustion release heat；In stove, thermal chemical reaction is with oxidation
Reaction is main, and reduction reaction assists, and is easily generated secondary pollution；When rubbish burns in stove, cross oxygen quotient big, First air, two
Secondary wind infeed amount is big, and in flue gas, dust content is higher, affects heat reclaiming system and smoke processing system relatively big, easily amasss
Ash, exhaust gas volumn is relatively big, reduces thermal conversion efficiency；The gasification furnace not being separately provided and incinerator, can only process rubbish by several times,
Cannot realize large-scale rubbish continuous gasification burning disposal, garbage treatment quantity is less.
