Description
Technical field
The utility model belongs to a kind for the treatment of apparatus of material, especially a kind for the treatment of system device that relates to the coal dust ash of flyash ash, and the flyash that is mainly used in flyash field that the flyash that produces in the thermal power generation process is piled up is reprocessed processing.
Background technology
At present, thermal power generation is still the power source of China's maximum, and its shared Chinese total installation of generating capacity is about more than 70%; Thermal power generation mainly refers to use the thermal coal generating, and the employed coal of thermal power generation accounts for more than 50% of industrial coal.These coals are after the unit burning through thermal power generation, will form coal ash, since present thermal power generation adopt coal all be coal dust through processing, so formed coal ash also becomes the coal ash of powdery after the burning, be commonly referred to as " flyash ".Flyash is to receive the thin ash of catching the flue gas behind coal combustion, flyash is the main solid waste that the coal-burning power plant discharges, these flyash are general all to be deposited in the selected ash field through carrying as waste material, at present, China power plant discharges waste product flyash with 1.8 hundred million tons speed every year, has accumulated at present 2,000,000,000 tons.Thermal power generation large reluctant public hazards have for a long time been become.Along with the development of power industry, the flyash discharge capacity of coal-burning power plant is also increasing year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; Can cause the river to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology.On the other hand, also contain a certain amount of combustible in the power plants flyash, in the flyash of about 1.8 hundred million tons of China's year amount dischargings, because of the used a variety of causes such as coal that burn, cause the too high part of phosphorus content to account for 50%, thereby can't obtain fully and reasonably utilizing directly with its processing, this also is a kind of waste, and since flyash output considerably beyond actual needs, for seeking new application, be particularly useful for production and the concrete preparation of high-performance building of cement, people show more and more keen interest.But the existence that surpasses the uncompleted burned carbon of certain content is a unfavorable factor, and it has hindered the possibility of coal ash instead tradition raw material in high-level application.Therefore, how to solve carbon---ash content from problem, be the key point that improves the comprehensive utilization ratio of flyash solid discarded object.Society at current resource growing tension is necessary to be studied to this more.Floatation is as mineral separation method commonly used, aspect fly ash charcoal-removing, have a wide range of applications, but now generally mostly just take a flotation for the processing of coal dust ash, so just be difficult to obtain effective flotation effect, so still be necessary this is improved.
Though many coal dust ash treatment technology is arranged now, about how combustible few in the extract powder coal ash especially processes the flyash of original flyash field, lacks the technology of maturation.
Only find two pieces of therewith relevant patent literatures by patent retrieval:
1, the patent No. is CN200410098980.X, the utility model name is called the utility model patent of " flotation column process of carbon residue in a kind of separation of fine coal ash ", this patent discloses the flotation column process of carbon residue in a kind of separation of fine coal ash, is made of ore pulp preparation, flotation column sorting, product dehydrate three parts.Adopt the dual-jet flotation column, and cooperate corresponding feed and dehydration equipment, form flotation column-chamber-type press filter floatation process, remove the uncombusted carbon granule in the flyash.With high concrete carbon fly ash and the water agitator of packing into, be prepared into the ore pulp that meets the floatation concentration requirement through the impeller stirring, the ore pulp for preparing is delivered to the feeding mouth of flotation column with screw pump, the ore pulp pan feeding obtains flotation concentrate slurry carbon residue and flotation tailing pulp flyash through the sorting of dual-jet flotation column, processing by the chamber-type press filter dehydration obtains respectively final carbon residue product and flyash product.Although this patent has related to the flotation technology of the carbon residue of coal dust ash, just adopts single flotation column process, so the effect of flotation is bad, can not solve the coal dust ash transportation problem of original ash field.
2, the patent No. is CN200810030730.0, the utility model name is called the utility model patent of " a kind of activating treatment method of flyash ", this patent discloses a kind of activating treatment method of flyash, flyash is put into mixer, when the flyash temperature reaches 110～150 ℃, divide three stirrings on one side with aluminate coupling agent, slowly add blender on one side, then every minor tick 2～5min adds stearic acid, continues to stir 15～20min.This patent selects aluminate coupling agent and stearic acid as activator, and rationally limit its addition, flyash as raw material is carried out activation processing, and aluminate coupling agent closely combines two kinds of components as " molecular bridge " between the organic component in flyash and the artificial asphalt; Stearic effect is collaborative aluminate coupling agent activating fly ash surface, is mainly used in coal ash for manufacturing is made artificial asphalt, can effectively prevent from making the segregation of flyash in the rear artificial asphalt.This patent is just mentioned the cremate of coal dust ash and is processed, and does not mention the carbon residue that how to extract wherein.
In addition, find to report relevant for the paper that coal dust ash carbon residue is processed by the Scientific Periodicals retrieval, representational have:
1, " flyash " the 06th phase in 2010, " the flyash Floatation of Removal Carbon process system design and optimization " by name that author: Liang Jijun, Wang Zhuanzhuan, Guo Lipeng and Xu Dali deliver; Paper, this paper introduce the design of flyash Floatation of Removal Carbon process system, have analyzed problem, Optimized Measures and practical application effect that system exists.And the problem of having mentioned in the text the existence of flyash Floatation of Removal Carbon process system mainly exists former flotation column chemicals dosing plant to adopt not good two subject matters of flotation effect of semi-automatic medicine system equipment FWX-3000 flotation column, and this is optimized design, but fundamentally do not improve method for floating.
By above-mentioned analysis, it is bad that the processing method that can find out existing flyash exists treatment effect, especially the coal dust ash of original ash is existed that transporting equipment is many and the occupied ground area is large, maintenance defective large and that easily cause plant environment to pollute because failing the leakage of ash silo pump, especially for the powder ash that becomes the ash field, the coal dust ash has formed a plate, so being difficult to adopt above-mentioned carrying method carries, therefore how to process the coal dust ash of existing flyash ash field, extract carbon residue wherein, need further to be improved.
