Description

Stoker fired grate formula refuse gasification CIU and synthesis gas straight tube combustor
Technical field
This utility model belongs to solid waste incineration processing technology field, more particularly to a kind of stoker fired grate formula rubbish gas Change CIU and synthesis gas straight tube combustor.
Background technology
Existing technology of garbage disposal mainly has burning, sanitary landfills, compost, waste recovery etc..In garbage disposal routine In technology, burning disposal has reduced training substantially, and innoxious thorough, occupation of land amount is little, and waste heat energy is obtained by, and secondary pollution is few The advantages of, meet the strategic requirement of China's sustainable development.But with to the continuous improvement of environmental requirement, how strengthening both at home and abroad Control to secondary pollution is particularly important.Therefore, refuse pyrolysis gasification burning technology is gradually shifted onto the road of industrial applications On, all kinds of incineration technologies are primarily now used especially for domestic rubbish, the extensive industrialization of gasification burning technology will The technological innovation for bringing domestic garbage disposal industry is regenerated.
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 of laboratory Plinth research is a lot, also has applied research, such as:Rotary kiln type, vertical and fluidized bed type destructive gasifying or temperature gasification and high melting skill Art etc..But in Technique Popularizing application or there is a definite limitation, 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, wherein having in body of heater using mechanical type backstepping fire grate, forwards fire grate or combined fire grate, also adopts With fire grates such as chain-plate type and drum-types.
In sum, typical incinerator, respectively there is its own advantage, but needs what is solved in China's practical application Problem and shortage:
