Description
Technical field
The utility model relates to one way of life incineration of refuse flyash filter cake drying system.
Technical background
The refuse incineration and power generation journey that recent domestic rises, for innoxious, minimizing, the resource of domestic waste contribute.But in incineration of refuse flyash, contain heavy metal with the pollutants such as bioxin are shown great attention to by environmental administration of various countries.In China, " national Hazardous Waste List " clearly specifies: domestic garbage incineration flyash belongs to hazardous waste, therefore needs it to carry out harmlessness disposing.
Cement kiln altogether disposal technology, because having the advantage of effectively fixing heavy metal and thoroughly abolishing bioxin, becomes effective processing mode of incineration of refuse flyash.But in flying dust, contain a large amount of chloride salt materials, not only affect cement product quality, also can be in the high temperature section volatilization of cement kiln, low-temperature zone condensation, thus cause the corrosion of cement kiln skinning, affect cement kiln and normally move.
The patent No. is that the Chinese invention patent " a kind of method for the treatment of incinerated fly ash of domestic garbage with cooperation of cement kiln " of ZL201010162532.7 discloses flying dust is washed to the method that is delivered to cement kiln high-temperature section calcining after pretreatment-drying and processing, the method adopts three grades of washing treating apparatus by water washing tank and vacuum filter combination to wash and Separation of Solid and Liquid flying dust, filtrate after vacuum filter Separation of Solid and Liquid enters sewage-treatment plant processing, and filter cake enters cement kiln high-temperature section calcining after drying machine drying.The method adopts water-washing technique to carry out pretreatment to flying dust, effectively reduce chloride salt material harmful to manufacture of cement in flying dust, increase substantially the ability of cement kiln synergic processing flying dust, but in service at Practical Project, because CaO content in flying dust is high, particle diameter is little, specific area is large, make the flying dust filter cake moisture content that obtains through Separation of Solid and Liquid high, large and the caking of viscosity, cause flying dust filter cake in drying course, the inner frequent knot wall that occurs of dryer, blockage problem, have a strong impact on normally carrying out of drying, after drying in addition, tail gas contains a small amount of pollutant, do not process and be directly discharged in atmosphere, environment is exerted an influence.
Utility model content
In order to solve problems of the prior art, the purpose of this utility model is to provide one way of life incineration of refuse flyash filter cake drying system, and flying dust filter cake drying course is normally carried out, and after drying, tail gas is thoroughly processed simultaneously.
To achieve these goals, the utility model adopts following technical scheme:
One way of life incineration of refuse flyash filter cake drying system, comprise conveying worm, colter mixer, pan feeding scraper-trough conveyer, dryer, dust-precipitator, flying dust finished bin, conveyer, blower fan and quality coal in cement kiln systems, wherein, conveying worm outlet is connected with colter mixer the first entrance; Colter mixer outlet is joined with the upper shed of pan feeding scraper-trough conveyer; Pan feeding scraper-trough conveyer under shed is connected with dryer feeding mouth; Dryer outlet is connected with dust-precipitator import by pipeline, and dust-precipitator is provided with 2 outlets, and one is material outlet, and this material outlet is connected with flying dust finished bin; It two is tail gas outlet, and this tail gas outlet is connected with blower fan import by pipeline; Fan outlet is connected with quality coal in cement kiln systems by pipeline; Quality coal in cement kiln systems is connected with dryer air inlet by pipeline; Flying dust finished bin is provided with 2 material outlets, and one of them outlet is connected with conveyer one end, and the conveyer other end is connected with colter mixer the second entrance.
Described colter mixer is continuous horizontal type colter mixer, and described dryer is vertical air flow dryer, and described dust-precipitator is bag filter, and described conveyer is conveying worm.
Described pan feeding scraper-trough conveyer is provided with twice air valve, completely spreads and is inlaid with high molecular weight ptfe plate in pan feeding scraper-trough conveyer inwall surrounding.
The outlet that described flying dust finished bin is connected with conveyer is provided with rotary feeder.
Described fan outlet is connected with the grate-cooler high temperature section of quality coal in cement kiln systems by pipeline, and the grate-cooler low-temperature zone of quality coal in cement kiln systems is connected with dryer air inlet by pipeline.
Know-why of the present utility model is: because the flying dust filter cake moisture content after Separation of Solid and Liquid is high, large and the caking of viscosity, directly enter dryer and can cause dryer internal junction wall, buildup and obstruction, the utility model is by mixing flying dust filter cake a certain proportion of oven dry flying dust, after utilizing back mixing that flying dust filter cake is mixed with oven dry flying dust, moisture content significantly declines, viscosity significantly reduces, flying dust filter cake does not lump simultaneously, be graininess, very loose, enter after dryer through pan feeding scraper-trough conveyer, dry very soon under hot-air flow effect, dryer inside also just there will not be knot wall, buildup and blockage problem, in addition, the tail gas that oven dry produces after gathering dust contains a small amount of pollutant and more steam, sent into the grate-cooler high temperature section of quality coal in cement kiln systems, pollutant obtains mineralising processing under high temperature action on the one hand, eliminated its harm risk to environment, steam has fine effect to clinker cooling on the other hand.
The beneficial effects of the utility model are: (1) adopts back mixing to reduce flying dust filter cake moisture content and viscosity, and makes material very loose, efficiently solve inner frequent knot wall, the blockage problem occurring of dryer; (2) be combined with quality coal in cement kiln systems, after drying, tail gas obtains thoroughly effectively processing, and has eliminated its impact on environment; (3) the utility model is novel unique, reliable and practical, has solved engineering roadblock, has ensured that flying dust filter cake is dried normally to carry out, the perfect technique for the treatment of incinerated fly ash of domestic garbage with cooperation of cement kiln.
