Description
Technical field
The present invention relates to the resource benefits of high-salt wastewater after garbage flying ash processing technology field more particularly to a kind of washing of flying dust
Use system and method.
Background technique
Incineration of refuse flyash be in municipal consumer waste incineration disposal process the trapping object of flue gas purification system and flue and
The bottom ash of chimney bottom sedimentation.Containing pollutants such as heavy metal, benzene homologues, dioxin in incineration of refuse flyash, arranged in China
For hazardous waste HW18.
Enter landfill yard after solidification and stabilization, is the flying dust processing mode of international mainstream, refers to and pass through physical-chemical method
Harmful substance is fixed to or is included in one of inertia curing substrate innocent treatment procedure.The purpose is to make the dirt in waste
Dye component is presented chemical inertness or is contained, and keeps it safer during transport is with disposition.Stabilize landfill
Disposal options can occupy a large amount of soil.Under the action of after Closure of landfill site through going through nature, harmful substance, which has, gradually to be discharged
A possibility that.Simultaneously industrialization promotion is significant and gesture exists for the flying dust processing technique and technique for further developing stability and high efficiency
It must go.
Cement kiln synergic processing incineration of refuse flyash is to be added to manufacture of cement pretreated flying dust is passed through as raw material
In the process, instead of part of cement raw material while, the organic pollutants such as the dioxin being enriched in flying dust have been effectively removed, have been realized
The disposal of resources of flying dust.Due to containing a large amount of Cl-and heavy metal element in flying dust, in order to avoid to manufacture of cement work
Skill impacts, it is necessary to pre-process to it.Largely studies have shown that the method using water-washing pre-treatment can effectively be gone
Except the Cl-in flying dust, avoid causing system balling and putty etc. because Cl- is excessively high.
What Beijing Building Materials Science Research Institute Co had invented that a kind of garbage flying ash washes buck recycles work
Skill (CN102020388A), the technique carry out suspended matter separation, removing heavy metals ion, deliming magnesium ion, filtering, mechanical compression and
Multiple-effect evaporation step, the innovative point of technique is the removal of suspended matter, heavy metal ion, calcium ions and magnesium ions, but cooperates with to cement kiln
Dispose flying dust always influence factor --- the removing process of chloride ion does not have further investigated and research.
A kind of water washing pretreatment method for making fly-ash from incineration harmless (CN1947872A) has been invented by Shanghai University, this method be
Water washing flying dust under normal temperature and pressure removes a large amount of leachable anion and part heavy metal ion in flying dust.Make in its flying dust
Chlorine ions percent concentration drops to 1% hereinafter, simultaneously part washes out heavy metal, which is directed to specifically operate
Method and operating parameter, but corresponding lectotype selection is not provided, it is still necessary to suitable equipment completing technology routes in engineer application
Industrial application.
Guo Run Environmental Protection Technology Co., Ltd of BeiJing ZhongKe discloses a kind of washing melded system of incineration of refuse flyash
(CN104843923A), the filtrate (liquid of first-stage centrifugal machine B successively with the first intermediate pool, the first reaction tank, the second reaction tank,
Decalcification transfer tank, the connection of decalcification centrifuge, the cake outlet of decalcification centrifuge are connected to second level filtrate tank, the filter of decalcification centrifuge
Liquid outlet is successively with the second intermediate pool, water stabilization reaction tank, level-one stable regulation pond, two-stage stabilising conditioning tank, filtering
System, PH conditioning tank, stablize pond, MVR evaporator, clear water reserviors connection, alkali liquor storage tank respectively with the first intermediate pool, water stabilization
Reaction tank connection, level-one, two-stage stabilising conditioning tank sludge outlet be connected to respectively with mud reservoir, mud reservoir is by the road with one
Grade filtrate tank connection, the technical essential are to connect retouch in detail with structure with the equipment in softening process for flying dust washing
It states, makes flying dust water-washing process that there is practical operability, but the implementation method of washing dechlorination effect, operating parameter are not said
It is bright.
To sum up, the existing generally existing following problems of flying dust washing process: 1. is excessive using centrifuge, the separation to centrifuge
Ability does not make full use of；2. not considering risk of the addition to solution of flocculant, the addition of organic matter will lead to subsequent MVR points
