It is further characterized in that: described flying dust weighing cabin connects described first agitator by screw machine; Water system and/or drug delivery connect described second agitator respectively; Described flying dust weighing cabin, described medicament weighing cabin and described first agitator are respectively arranged with dust-removal cloth-bag; Described dust-removal cloth-bag on described first agitator is provided with first and takes out dirt blower fan; Described second agitator is provided with ash handling equipment; Described ash handling equipment comprises cylindrical shell, and described cylindrical shell is communicated with described second agitator, is provided with atomizer in described cylindrical shell, and the inherent described atomizer upper end of described cylindrical shell is provided with filter screen, described cylindrical shell is provided with second and takes out dirt blower fan; Described first agitator is spiral mixing agitator, and described second agitator is planet strrier.
In said structure of the present invention, flying dust storehouse connects flying dust weighing cabin by valve, medicament storehouse connects medicament weighing cabin by valve, flying dust weighing cabin is connected the first agitator with medicament weighing cabin respectively by valve, mixing agitator connects the second agitator by valve, flying dust weighing cabin and be provided with the first agitator between medicament weighing cabin and the second agitator, when carrying out flying dust and water mix and blend in the second agitator, effectively prevent from a large amount of dust-laden steam in the second agitator from scurrying in scale body causing scale body Dump gate and inside to harden material, ensure that weighing precision, ensure that the normal operation of blanking simultaneously.
Accompanying drawing explanation
Fig. 1 flyash curing treatment system of the present invention schematic diagram.
Detailed description of the invention
See Fig. 1, a kind of flyash curing treatment system, it comprises flying dust weighing cabin 1 and medicament weighing cabin 2, flying dust storehouse 3 connects flying dust weighing cabin 1 by valve 4, medicament storehouse 5 connects medicament weighing cabin 2 by valve 4, flying dust weighing cabin 1 is connected spiral mixing agitator 6 with medicament weighing cabin 2 respectively by valve, spiral mixing agitator 6 connects planetary stirrer 7 by valve 4, flying dust weighing cabin and be provided with spiral mixing agitator 6 between medicament weighing cabin and planetary stirrer 7, when the flying dust handled well in spiral mixing agitator 6 carries out flying dust and water mix and blend in planetary stirrer 7, effectively prevent from a large amount of dust-laden steam in planetary stirrer 7 from scurrying in scale body causing scale body Dump gate and inside to harden material, ensure that weighing precision, ensure that the normal operation of blanking simultaneously.
Flying dust weighing cabin 1 connects spiral mixing agitator 6 by screw machine 8; because when apparatus arrangement; the volume in usual ash silo and medicament storehouse is very large; so diameter is also just larger; also spacing is had between two storehouses; so common layout is placed on below a storage bin by wherein a weight scale and mixing agitator, the material of another storage bin then weigh after by helical feed to mixing agitator.
Flying dust weighing cabin 1, medicament weighing cabin 2 and spiral mixing agitator 6 are respectively arranged with dust-removal cloth-bag 17, realize the dedusting of flying dust weighing cabin 1, medicament weighing cabin 2 and spiral mixing agitator 6, dust-removal cloth-bag 17 on mixing agitator 6 is provided with first and takes out dirt blower fan 18, first takes out dirt blower fan 18 starts, be negative pressure in mixing agitator 6, be conducive to weight scale quickly discharging material.
Water system 9 and/or drug delivery 10 connect planetary stirrer 7 respectively, carry out harmless process to the flying dust entering planetary stirrer 7, and after process, the stabilizing fly ash product of meet the requirement of environmental protection carries out further landfill.Achieve the harmless landfill of harmful flying dust, effectively protect environment.
Planetary stirrer 7 is provided with ash handling equipment 11, ash handling equipment 11 comprises cylindrical shell 12, cylindrical shell 12 is communicated with planetary stirrer 7, atomizer 13 is provided with in cylindrical shell 12, cylindrical shell 12 inherent atomizer 13 upper end is provided with filter screen 14, cylindrical shell 13 is provided with second and takes out dirt blower fan 15, the dust that the atomized water adverse current that atomizer ejects catches in gas forms water droplet, then water droplet is down in mixer due to initial velocity inertia and deadweight, the material that part is flown upward filters 16 by filter screen, the flying dust that effectively prevent in whipping process flies upward, avoid the pollution of environment, effectively ensure that operation and the health of upper level equipment simultaneously.
Below in conjunction with accompanying drawing, operation principle of the present invention is described:
Flying dust and medicament enter flying dust weighing cabin 1 respectively respectively by flying dust storehouse 3 and medicament storehouse 5 and medicament weighing cabin 2 carries out entering in spiral mixing agitator 6 after leading independence weighs, two kinds of powder materials after fully mixed first, enter in next stage planetary stirrer 7 again, industry water and/or liquid drug solutions also enter in planetary stirrer 7 simultaneously, if when the material inside medicament storehouse can not make the harmful components meet the requirement of environmental protection in flying dust, then just also need to add liquid drug solutions again after flying dust enters planetary stirrer and process further; If when the medicament in medicament storehouse can make the harmful components meet the requirement of environmental protection of flying dust, then only need add industry water in planetary stirrer and these two kinds of materials are further mixed.In mixing agitator 6, structure is simple, has effectively completely cut off steam and has entered weighing-appliance, import and export simultaneously and be flange, expediently descend equipment connection by import and export twice valve.Secondly independently dust-removal cloth-bag 16 is set on flying dust weighing cabin 1, medicament weighing cabin 2 and mixing agitator 6, and configure pulse backblowing cleaning system, ensure that Long-Time Service dust does not stick with paste bag, mixing agitator dust-removal cloth-bag 16 arranges first simultaneously and take out dirt blower fan 17, during charging, first takes out dirt blower fan 17 starts, and is negative pressure, is conducive to weight scale quickly discharging material in mixing agitator 6.Special dedusting ventilate mechanism is set on star agitator 7 again, herein owing to there being a large amount of steam, bag-type dust is inapplicable, select wet ash removal device 11, wet dust removal adopts the industry water shunting cleaning entering mixer, sewage after cleaning again enters mixing and blending machine and mixes with flying dust, water source can not be wasted and cause secondary pollution, take out dirt blower fan simultaneously, make to produce certain negative pressure in planetary stirrer 7 by taking out dirt blower fan, dust-containing water steam in planetary stirrer 7 is discharged after being towed to the concentration filter dedusting of dust arrester place, both prevented dust-laden steam from entering higher level equipment, when agitator Dump gate can also be avoided to open, in agitator, dust-laden steam sprays along discharge port.
In the present embodiment; first agitator is spiral mixing agitator; second agitator is planetary stirrer; other agitators can certainly be adopted; as long as the stirring requirement of flying dust material can be met; be all within the spirit and principles in the present invention, its any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
