Description

A kind of carbon-based material and preparation method thereof based on carbonaceous dust collection powder
Technical field
The present invention relates to the reutilization technology field of dust collection powder waste more particularly to the utilization sides of dust collection powder waste Method.Suitable for a kind of preparation method based on carbonaceous dust collection powder.
Background technique
It, will be abundant after flue dust collecting in metallurgical process (roasting, sintering, melting, blowing, distillation etc.) a large amount of flue dust of output It utilizes, can both improve working conditions, and prevent from polluting, and the energy one of the various useful constituents of synthetical recovery, obtain raw material sufficiently Reasonable utilization.
It is a large amount of due to being produced during the broken of raw material, conveying and process operation such as in carbon anode production process Powder.Since particle is subtle, electric conductivity is good, it is being recycled and is discharging in transportational process, it is easy to which generation is flown upward, and is made At environmental pollution.For a long time, dust collection powder discharge is always the long-standing problem for restricting China's carbon industry clean manufacturing.Mesh To these dust collection powders, professional recovery and utilization technology, the processing mode generally used are not to take out at a low price for the preceding country, this place Reason mode causes the waste of resource, and in handling, transport, powder is easy to leak, and causes the secondary pollution of environment.Patent 201611065051.8 propose a kind of processing method of coking coal treatment process dust-removing powder, by dust-removing powder, miscellaneous coal and tar slag After mixing, coal briquette is pressed into using roller briquetting machine.Liu Zhixiang et al. (Yunnan metallurgy, 2011,40 (4), 66-69.) will gather dust Powder is incorporated scratch system in proportion, participates in production main flow, realizes recycling of the dust as raw material.Start beautiful minister in ancient times (light metal, 1992,49-5110, (10), 38-41.) adjustment raw material powder purity, and proportion scale is modified, match dust collection powder as carbon anode Material is realized and is recycled.Li Xiaomings etc. (material science and technique, 2018,26 (4), 34-41.) produced pre-baked anode carbon blocks A large amount of dust collection powder mixed acid processes promote carbon grade in journey, as anode production raw material or filler material Returning utilization.Guo's generation equality (charcoal element Technology, 2017,36 (3), 48-50.) have studied calcining refinery coke by rotary kiln generation dust collection powder be measured analysis, be it is subsequent That realizes dust collection powder utilizes offer value support.Number of patent application 201710837977.2 will be during electrolytic aluminium and carbon production Asphalt slag, waste coke oil, dust collection powder, anode scrap powder and soft anode scrap of generation etc. are solid, dangerous waste No Assets are shaped to carry out again after carbon turns It utilizes.
Currently, the main application about dust collection powder is as being recycled back to raw materials for production.The dust collection powder that calcining petroleum coke generates Also the detection and analysis of product are only limitted to, high-valued utilization is not obtained.Meanwhile most of dust collection powder resource is confined to original production It uses, consume in region.Molding carbon-based material is a kind of material of hole prosperity, has chemically and thermally mechanical stability outstanding With good mechanical strength, with the progress and the improvement of people's living standards of science and technology, the purposes for forming carbon-based material will It is more and more extensive.More environmentally-friendly new energy is actively being found, while implementing new energy strategy, is also more being needed existing Waste is reduced on the basis of some energy, reduces environmental pollution.Solid waste is realized in the renewable sources of energy, energy saving resource Change and utilize, plays certain positive effect to alleviate resource scarcity, reducing environmental pollution.
