Description
Technical field
The present invention is a kind of waste gas purification exhaust system, cooperates with power generation by waste combustion with sludge more particularly to a kind of house refuse
Waste gas purification minimum discharge system.
Background technique
Chinese Ministry of Environmental Protection's publication " the big or middle municipal solid waste pollution environment in the whole nation in 2016 prevents and treats annual report " display 2015,246
185,640,000 tons of a big or middle Municipal Domestic Garbage Output.China's urban population is more, soil is few, solves the problems, such as that garbage disposal can only
Waste incineration and generating electricity.
By 2015, China dewatered sludge annual output about 4.9x107t.According further to related prediction, China's municipal sewage amount
Biggish growth is also had in the coming years, sludge quantity will further increase sharply.By space constraints, sludge incineration minimizing is must be by
Road.
China's house refuse amount of having the characteristics that is big, complicated component, dirt, organic substance in rubbish storage hole vulnerable to
To microorganism effect and putrid fermentation, generate the existing peculiar smell such as a certain amount of ammonia, hydrogen sulfide, organic amine, methane again it is harmful
Gas.Under aerobic and anaerobic conditions, foul gas main component is respectively ammonia and H2S.When burning disposal, since China is raw
Refuse thermal value living is lower, needs to add coal dust firing.In addition, due to house refuse complicated component, it will not during burning disposal
Generate secondary pollution, especially dioxin, heavy metal etc. avoidablely, cause incineration flue gas can not qualified discharge, pollute environment,
It is detrimental to health.
The heavy metals such as iron, manganese are reduced in water, form the compounds such as ferrous sulfide with the sulphur in water, form a large amount of absorption
The sludge of FeS, MnS particle.Due to being rich in a large amount of organic matter, calorific value is high, and sludge can use burning disposal.But after desiccation
Sludge incineration can equally generate the secondary pollutions such as dioxin and heavy metal.
The technique of existing waste incineration and generating electricity waste gas pollution control and treatment mostly uses greatly SNCR+ semi-dry desulphurization+activity powdered carbon+cloth bag to remove
Dirt device；And refuse odor is washed using bioanalysis or chemical agent, there are the at high cost or period it is long the problems such as.Sludge incineration exhaust gas
Processing main technique is SNCR+ activity powdered carbon+bag-type dust+alkali liquid washing, its main feature is that Hg content is higher in flue gas.In sludge
S/Cl ratio is 7~10 times of domestic waste, and the presence of high concentration sulphur can hinder dioxin and furans in incinerator and cigarette
Generation in road.Also, the independent cost of disposal of sludge is high.Cooperate with power generation by waste combustion useless with sludge so being badly in need of a kind of house refuse
Gas purifies minimum discharge system.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of solution MSW Incineration Plant stench, dioxin is super
The technology that the discharge content of the effumabilities metallic element such as Hg is obviously increased with temperature raising in mark discharge and sludge incineration
The house refuse of problem cooperates with power generation by waste combustion waste gas purification minimum discharge system with sludge.
In order to solve the above technical problem, the present invention provides house refuse cooperate with sludge power generation by waste combustion waste gas purification super
