Abstract
The invention discloses a method for improving treatment capacity of industrial wastes of a rotary kiln. The method comprises the following steps: adjusting an operation process, stabilizing the operation and ensuring that various indexes of clinker are qualified; and adjusting the way of putting the wastes, ensuring that calcination of the wastes is smooth, classifying the types of the wastes, adjusting burdening of raw materials and ensuring the stability of the raw materials. According to the method for improving the treatment capacity of the industrial wastes of the rotary kiln, disclosed by the invention, the defects of unreasonable putting way, unreasonable classification, complex operation process and the like in the prior art can be overcome, and the advantages of reasonable putting way, reasonable classification and simple operation process are realized.
Description
Technical field
The present invention relates to cement processing technique field, particularly, relate to a kind of method improving rotary kiln trade waste treatment capacity.
Background technology
Guangxi subsidiary factory of Yu Feng cement limited-liability company one cooperates with Liuzhou gold sun industrial waste process company, own technology is adopted to carry out technological transformation for the treatment of trade waste to former rotary kiln, alleviate industrial refuse processing pressure in a short time, solve landfill and burn the problem that fundamentally can not process industrial refuse. make rational use of resources, no longer newly-built landfill yard and incineration plant, make industrial refuse obtain the process of more economical safety and environmental protection:
1, China is also quite weak to the process of trade waste at present, mostly can only simple process. and cause severe contamination to greenbelt air water body and soil, its pollution level and hazardness are much larger than waste itself.
2, rotary kiln incineration is various containing flammable waste, can utilize its residual calorific value, and the residue of its burning of process that can also be thoroughly clean, eliminates secondary pollution hidden danger, cement rotary kiln wide accommodation in addition, the waste of various form of can dissolving.
3, rotary kiln process waste than way economy such as newly-built destructor plant and incineration plant many, produce effects faster, greatly reduce construction cost.
Trade waste can not obtain the process of environmental protection mostly.Cement kiln process trade waste, also can affect to grog, introduces some objectionable constituent as potassium, sodium, chlorine, sulphur etc., kiln system may be caused to bond, blocking, and these factors all can have an impact to kiln system.Utilize rotary kiln process trade waste not only to want environmental sound, also will guarantee kiln process stabilizing, avoid having an impact to clinker quality.
Confirm by analysis, the treatment capacity major cause that have found affects rotary kiln trade waste is: operation thought disunity, waste are thrown in, waste kind is many.
Realizing in process of the present invention, contriver finds at least to exist in prior art the defect such as input mode is unreasonable, the unreasonable and operating process of classifying is complicated.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of method improving rotary kiln trade waste treatment capacity, to realize, input mode is reasonable, classification is reasonable and the simple advantage of operating process.
For achieving the above object, the technical solution used in the present invention is: a kind of method improving rotary kiln trade waste treatment capacity, comprising:
A, adjustment operating procedure, stable operation, ensures that the indices of grog is qualified;
B, adjustment waste throw in mode, guarantee that calcining waste is steady;
C, classify to waste kind, adjustment raw meal proportioning, ensures the stability of raw material.
Further, described step a, specifically comprises:
Ensure into kiln material stable equilibrium, plus-minus coal is resolute in time;
Select high-quality kiln coal, ensure to stablize into kiln coal and batching.
Further, described step b, specifically comprises:
Determine the position that feeds intake be applicable to, select the control of effective processing mode and burning waste speed;
Rotary kiln temperature controls at 1450-1500 degree Celsius.
Further, described step c, specifically comprises:
According to composition and the calorific value of trade waste, the processing parameter of raw meal proportioning and kiln is suitably adjusted;
The trade waste of rotary kiln incineration has: liquid waste oil, paste, bulk, Powdered.
The method of the raising rotary kiln trade waste treatment capacity of various embodiments of the present invention, owing to comprising: adjustment operating procedure, stable operation, ensures that the indices of grog is qualified; Adjustment waste throws in mode, guarantees that calcining waste is steady; , waste kind is classified, adjustment raw meal proportioning, ensures the stability of raw material; Thus can overcome that input mode in prior art is unreasonable, unreasonable and that operating process is complicated defect of classifying, with realize input mode rationally, classification rationally and the simple advantage of operating process.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from specification sheets, or understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide a kind of method improving rotary kiln trade waste treatment capacity.
In technical solution of the present invention, the annual burning disposal trade waste 1200 tons of rotary kiln.Zero cost, process trade waste does not need to spend money on.
the develop countermeasures of technical solution of the present invention:
Implementation process:
Enforcement one, industrial waste species multicomponent complexity
The waste kind that rotary kiln can burn is many, applied widely, no matter is solid, liquid, bulk or paste, and common waste can burn totally at rotary kiln or decomposing furnace.
Test effect: the trade waste of subsidiary factory's rotary kiln incineration has: liquid waste oil, paste, bulk, Powdered etc.
Enforcement two, trade waste contain harmful ingredients
Adopt novel refractory, use the refractory materials containing ZrO2, absorb alkaline matter and solidify and be covered in kiln lining surface, prevent the further infiltration of alkalescence;
Rotary kiln temperature is high, ranges up to 1450-1500 degree Celsius, and waste material has about 6 seconds in high-temperature zone residence time length, and objectionable constituent all can thoroughly be decomposed;
Waste, at the residue of rotary kiln combustion, even if contain the objectionable constituent such as sulphur, chlorine, also all can be melted in cement clinker crystal, can not overflow again, can not cause secondary pollution.
Test effect: after calcined by rotary kiln trade waste, grog indices qualification rate is not affected substantially.
Enforcement three, field control
Dynamics is patrolled and examined at reinforcement scene,
Formulate the regulatory of calcining waste.
Test effect: on-the-spot waste calcinating speed is steady, and clinker quality is qualified.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
