Burn heating boiler.
Background technique
With the progress of human society, influence of various types of rubbish to environment is got worse, and especially water content is small
In 70% solid waste, they are classified broadly into three types, such as non-hazardous waste (such as house refuse), common
Bazardous waste (as having those flammable or reactive wastes) and special bazardous waste (such as radioactive waste
And clinical waste) etc..
The method of mesh Pretreatment Waste Materials, most common is landfill or outdoor heap abandoning processing, occupies a large amount of soils, simultaneously
Pernicious gas in rubbish causes serious pollution to atmosphere, soil and water source, has not only broken up ecological environment, has also seriously endangered
Human health.The another method of offal treatment is to burn, and is burned at present a variety of including bazardous waste as handling
The widely used method of waste its advantage is that treating capacity is big, volume reduction is good, innoxious thorough, and has thermal energy recycling effect.
However, incinerator can generate hypertoxic gas along with the elimination of waste.In addition, burning makes heavy metal, unburned chemicals etc. exist
The pollution of the new chemicals formed in combustion process.In other words, burn a large amount of wastes are decomposed and by empty gas and water and
Dust is disseminated into environment, has imputed to mankind offspring.The third method of offal treatment is pyrolysis, and pyrolysis is in no oxygen
In the case of by heating carry out material chemical breakdown, it is, in general, that the pyrolytic reaction of inorganic matter is fairly simple.Organic matter pyrolysis
When, due to that can generate side reaction, product composition is often more complicated.Such as when cracking petroleum hydrocarbon, except acquisition low molecular weight olefins
Outside, there are also because the side reactions such as polymerizeing, being condensed, and the product bigger than raw molecule amount is generated, such as tar, forms new dirt
Dye.Town and country refuse pollution at present, the combustion waste everywhere of stalk, Dark smoke billows, this is that pollution is also waste.The winter in town and country adopts simultaneously
It is warm also to rely primarily on coal as heat supply source, and coal is the wealth of our children and our children's children, saves the responsibility that utilization is for we.
Domestic Patent No. 200620020231X is disclosed a kind of " vortex smoke secondary combustion atmospheric boiler ", including
