Description

Cavity combustion chamber in stoker fired grate formula refuse gasification CIU and inverted cone-shaped
Technical field
The invention belongs to solid waste incineration processing technology field, more particularly to a kind of stoker fired grate formula refuse gasification to burn Cavity combustion chamber in burning system and inverted cone-shaped.
Background technology
Existing technology of garbage disposal mainly has burning, sanitary landfills, compost, waste recovery etc..It is conventional in garbage disposal In technology, burning disposal has that reduced training is obvious, it is innoxious thoroughly, occupation of land amount is small, and waste heat energy is utilized, and secondary pollution is few The advantages that, meet the strategic requirement of China's sustainable development.But with the continuous improvement to environmental requirement both at home and abroad, 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, especially for domestic rubbish primarily now using all kinds of incineration technologies, gasification burning technology widely industrialize by The technological innovation of domestic garbage disposal industry is brought to regenerate.
For many years, scientific research of the China to the gasification burning technology such as biomass, rubbish, be in progress a lot of, the base in laboratory Plinth research is a lot, also has application study, such as:Rotary kiln type, vertical and fluidized bed type destructive gasifying or temperature gasification and high melting skill Art etc..But Technique Popularizing is applied upper or a definite limitation be present, raw material type, garbage treatment quantity, secondary pollution control and economy Benefit etc. is principal element.
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, mechanical backstepping fire grate, forwards fire grate or combined fire grate are used in body of heater wherein having, is also adopted With fire grates such as chain-plate type and drum-types.
In summary, typical incinerator, respectively there is its own advantage, but need what is solved in China's practical application 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. with being on the increase for refuse production, sanitary fill such as mountain, garbage treatment quantity must be effectively improved, It can just meet the market requirement.
3. in face of strict pollutant emission requirement, secondary pollution control is the key problem for technically needing to solve.
4. in order to effectively increase economic efficiency, in rubbish heat treatment process, the organic efficiency of heat needs to improve.It is existing Rubbish heat treatment technics generally use boiler produce steam shift steam turbine power generation onto, whole transition heat efficiency losses are larger, place Identical quantity of refuse is managed, relative thermal losses and the raising heat exchanger effectiveness can of reducing improves the thermal efficiency.
5. conventional garbage is burned in mode and boiler applications, high-temperature dust removal is less or does not have, and some efficiency is also not high enough, high Effect dedusting and burning are had both less, the easy dust stratification of boiler, decline thermal conversion efficiency, so as to which lower power production, maintenance period are short Deng.
For example following two patents of invention of existing incinerator: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 Manage model comparision to fall behind, simply dry-burn-burn, solid combustion discharges the process of heat;Thermal chemical reaction is to aoxidize in stove Based on reaction, reduction reaction auxiliary, secondary pollution is also easy to produce;When rubbish burns in stove, oxygen quotient excessively is big, First air, two Secondary wind infeed amount is big, and dust content is higher in flue gas, and heat reclaiming system and smoke processing system are had a great influence, easily product Ash, exhaust gas volumn is larger, reduces thermal conversion efficiency;The gasification furnace and incinerator not being separately provided, can only handle rubbish by several times, Large-scale rubbish continuous gasification burning disposal can not be realized, garbage treatment quantity is smaller.
