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：

1., for characteristics such as China's house refuse water content height, complicated components, the technology of moving hearth is used, to rubbish Conveying capacity needs emphasis to consider.

2. being on the increase with refuse production, sanitary fill such as mountain, garbage treatment quantity must be effectively improved, Could meeting the market requirement.

3. require in the face of strict pollutant emission, 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 using boiler produce steam shift steam turbine power generation onto, whole transition heat efficiency losses are larger, place Reason identical quantity of refuse, relative thermal losses and the raising heat exchanger effectiveness of reducing can just improve the thermal efficiency.

5. conventional garbage is burned in mode and boiler applications, and high-temperature dust removal is less or does not have, and some efficiency is also not high enough, high Less, the easy dust stratification of boiler that effect dedusting and burning are had both, declines thermal conversion efficiency, and so as to lower power production, maintenance period is short Deng.
