Description

Flyash curing stabilisation brick making system

Technical field

This utility model is related to the process of produced flying ash after waste incineration and generating electricity, particularly a kind of flying dust brickmaking System.

Background technology

Building up and coming into operation with increasing garbage burning factory, the discharge capacity of China's incineration of refuse flyash is also got over Come bigger.The harmful substance such as heavy metal, dioxin, furan is contained, the heavy metal belonging to be controlled is dangerous in incineration of refuse flyash The category of waste.

What the innoxious process for treating application of flying dust was commonplace at present is cement solidification and two methods stablized by medicament.Water The required equipment of mud solidification, operation require simple, reasonable price, but the increase-volume amount after cement solidification method is processed is big, and cement A large amount of using meaning direct resource consumption and indirectly environmental pollution.In addition, flying dust after cement solidification with containing big During the organic domestic garbage mixing landfill of amount, in rubbish, contained Organic substance can be produced nitrogen dioxide gas, be had due to degraded The materials such as machine acid, water soluble sulfate, these compositions will reduce the stability of heavy metal after solidification.It can be seen that, it is used alone water Mud solidification method, understands extension over time and there is very big defect.Medicament stabilization method is to pass through chemistry using chemical agent Reaction, makes poisonous and harmful substance be changed into the process of dissolubility, low migration and hypotoxicity material.The stabilizer generally adopting has Calx, phosphate, bleaching powder, sulfide, macromolecule stabilizer and ferrite etc., but medicament stably can produce high concentration inorganic salt Waste water, needs to carry out postorder process, increases processing cost, more seriously the flying dust after chemicals treatment is still bulk, compares table Area is big, dioxin is possible to dissolution.

Utility model content

Utility model purpose：For the problems referred to above, the purpose of this utility model is that offer is a kind of solid to incineration of refuse flyash Change stable apparatus system, flying dust is made fragment of brick, carries out harmless treatment, safe, practical.

Technical scheme：A kind of flyash curing stabilisation brick making system, including flying dust warehouse, flying dust weighing cabin, original fluid container, molten Liquid weighing cabin, technique water pot, blender, feed mechanism, hydraulic molding brick making machine, PLC, described flying dust warehouse passes through institute State feed mechanism to be connected with described flying dust weighing cabin, described original fluid container, technique water pot are weighed with described solution by pipeline respectively Storehouse connects, and is also separately installed with dosing pump in described pipeline, and described flying dust weighing cabin, the outlet of solution weighing cabin are all connected into described Blender, described hydraulic molding brick making machine is connected with the outlet of described blender, and described PLC controls whole device system certainly Dynamic operation.

In described hydraulic molding brick making machine, there is shaping mould, described shaping mould can dismounting and change, can be according to institute The shape of the brick that need to make and more mold exchange.

Described feed mechanism is conveying worm.

Also it is connected with delivery pump between the outlet of described solution weighing cabin and described blender.

Beneficial effect：Compared with prior art, the utility model has the advantages that：Apparatus system achieves and waste incineration is flown The solidification stabilized treatment of ash, the cured brickmaking of flying dust, reduce spillage of material, processing cost is low, can reach flying ash medicament The Dual Stabilization effect of stable and cement solidification, improves the long-time stability of stabilisation product, save cement consumption and Increase-volume ratio, decreases the moisture content in flying dust after process simultaneously, solves the most urgent the asking that current garbage burning factory faces Topic, efficiently solves the harm that flying dust produces to ecological, environmental protective and health.

Brief description

Accompanying drawing is this utility model system schematic.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model it should be understood that these embodiments are only used for This utility model is described rather than limits scope of the present utility model, after having read this utility model, art technology Personnel all fall within the application claims limited range to the modification of the various equivalent form of values of the present utility model.

As shown in drawings, a kind of flyash curing stabilisation brick making system, including flying dust warehouse, flying dust weighing cabin, original fluid container, Solution weighing cabin, technique water pot, blender, feed mechanism, hydraulic molding brick making machine, PLC.

Flying dust warehouse is connected with flying dust weighing cabin by feed mechanism, feed mechanism can using conveying worm it is adaptable to Conveying to flying dust.

Original fluid container, technique water pot are connected with solution weighing cabin by pipeline respectively, are separately installed with dosing pump, chela in pipeline Mixture stock solution and fresh water (FW) pass through dosing pump and control respective addition according to configuration proportion, chelating agen are diluted with water, molten Liquid weighing cabin forms chelating agent solution.

Flying dust weighing cabin, the outlet of solution weighing cabin are all connected into blender, add material to be mixed, fly in blender Grey weighing cabin, solution weighing cabin all can be precisely weighed according to material proportion, thus adding required material in blender Amount, is also connected with delivery pump between the outlet of solution weighing cabin and blender.Hydraulic molding brick making machine is connected with blender outlet, liquid There is in molded brickmaking machine detachable shaping mould, in mixed material addition hydraulic molding brick making machine, suppress setting Fragment of brick.Described PLC controls whole device automated system operation.

This apparatus system adopts programmable controller controls, that is, adopt PLC to pass through parameter setting, by water, chela Mixture automatically puts into solution weighing cabin according to the configuration proportion value setting, and squeezes into after flying dust and each self-weighing of chelating agent solution Blender carries out mix and blend, and charging enters brickmaking machine and obtains fragment of brick.

This utility model first by liquid chelating agen and water mixed diluting, then by the solution after dilution with flying dust according to setting Ratio carry out mix and blend, be delivered to brickmaking machine after stirring and carry out brickmaking, incineration of refuse flyash is made fragment of brick so that flying dust There is while stablizing fixing shape and intensity, finally deliver to household refuse landfill sites landfill, it is easy to accomplish, material and energy Consumption is low, and processing cost is low, can reach that flying ash medicament is stable and the Duplex treatment effect of cement solidification, and stablizing effect is obvious Strengthen, improve the long-time stability of stabilisation product, save consumption and the increase-volume ratio of cement, on the basis of not using cement Reach the standard of country, saved household refuse landfill sites volume, decreased the moisture content in flying dust after process simultaneously, solved The problem the most urgent that current garbage burning factory faces, the harm that effectively solving flying dust produces to ecological, environmental protective and health.
