Description
Technical field
This utility model belongs to fume treatment technical field, is related to a kind of flue gas purification system, more particularly, to a kind of rubbish
Incineration flue gas system.
Background technology
With the quickening of Urbanization in China, domestic waste yield increases year by year.The annual life rubbish in the whole nation at present
More than 3.6 hundred million tons, wherein domestic waste accounts for hundred million tons of 1.5-1.6 to rubbish yield, and is increased with average annual 8% speed.Therefore,
Problem of Urban Waste has become one of public hazards of world today's most serious, clear up in time and dispose rubbish be build beautiful China and
Graceful, clean and tidy, civilized modern city conditio sune qua non.Waste incineration as innoxious the most thoroughly, volume reductionization the most notable,
A kind for the treatment of technology of resourcebility producing level highest, has become as the important skill of current international community domestic rubbish disposal
Art.But the nuisance species included in flue gas of refuse burning is more, including ash, hydrogen chloride (hcl), fluohydric acid gas (hf),
