Description
Technical field
The present invention relates to a kind of blast furnace mineral hot furnace slag to cure the high, normal, basic waste heat recycling system of heat, specifically one kind
Blast furnace and ferronickel smelting mineral hot furnace clinker cure the high, normal, basic waste heat recycling system of heat, belong to afterheat of slags recovery technology neck
Domain.
Background technology
At present, due to environment, requirement that is energy saving and reducing cost etc., domestic and international each steel plant all pay much attention to pair
The research of secondary resource comprehensive utilization technique.
A kind of waste residue discharged when blast furnace slag is manUfaCtUre of pig iron from blast furnace.Due to modern age ore dressing and the hair of ironmaking technology
Exhibition, the blast furnace quantity of slag of pig iron output per ton have greatly reduced, and in general, furnace charge grade reaches 60%-66%, often produce 1t lifes
Iron, you can production clinker 250-300kg..Since blast furnace slag yield is very big, if not fine land productivity is used, not still to secondary resource
Significant wastage, and pollution on the environment is also very big.So many iron companies all comprehensively utilize blast furnace slag
Studied.
At present, tens countries are used using blast furnace slag as a kind of goods and materials in the world, but the recycling of sensible heat is asked
Topic is never resolved, and currently, most blast furnaces all use flush slag, and blast-furnace cement sensible heat is used for power generation etc. of warming oneself.But
Summer and the place without heating system, this portion of energy can only waste, and in blast furnace waste heat recovery field, blast furnace slag is shown
It is also finally maximum target, but due to the particularity of blast furnace slag, it is larger to solve this problem difficulty that recuperation of heat, which is,.Often produce 1t lifes
Iron wants 0.3~0.6 slag of by-product, and slag per ton contains（126~188）The sensible heat of x104Kj, equivalent to the energy of 30~40Kg heavy oil
Amount, it is seen then that either from amount or from matter, clinker sensible heat is all high energy value.Recycling this part of waste heat can save largely
The energy.
From the 1970s, steel country is mainly produced as Japanese, the U.S., Britain, Germany and Sweden, from
Energy saving and environmentally friendly purpose is set out, and the utilization of active development clinker resource, some countries have also set up specialized agency for this, such as day
Comprehensive utilization of slag technology, is also classified as the emphasis scientific research class of Ministry of International Trade and Industry by this steel slag sensible heat comprehensive utilization technique committee
Topic.
Blast furnace slag is formed by non-volatilization component in ash content in gangue, fuel in iron ore and solvent (being usually lime stone)
Material, its main component calcium oxide, magnesia, alundum (Al2O3), silica, account for 95 % of blast furnace slag total amount.It is high
Clinker belongs to phyllosilicate material, and chemical composition is similar to natural crystal, portland cement, can replace natural rock and be used as
Cement producting material etc..Domestic blast furnace slag will be mainly used as cement raw material within the longer term.At present, with after Water Quenching
There are new water consumption is big, clinker physical thermal can not recycle and the pollutant emission such as sulfur dioxide, hydrogen sulfide for blast furnace slag cement
Problem, therefore blast furnace Slag treatment development trend is while slag particle is turned to cement raw material using dry method, efficiently utilizes stove
Slag sensible heat.
It is domestic that some researchs were also carried out in terms of heat energy of blast furnace recycling and dry granulation.The 50's of 20th century, once
In blast furnace residue channel end, compressed air or high steam are passed in nozzle as blowing media, will be without any quenched, tune
The liquid slag of temperature processing is directly blown into slag wool fiber.Though this method takes full advantage of the sensible heat of slag, production cost is very low,
Price is also cheap, but because domestic blast furnace slag is that basic slag, material property are short, is not appropriate for directly into fibre, so this slag
Cotton fiber diameter is short and thick, its production and work progress environmental pollution are serious in addition, are eliminated already.Pan Gang research institutes were once
Simulated experiment was done the eighties.At that time, mainly found new outlets, will pass through for the titanium-containing blast furnace slag of cement raw material cannot be made
The titanium-contained slag fragmentation of dry process is made slag sand and is used to build afterwards to a certain extent, without being considered as needed for cement raw material
Glass phase (amorphous state) content.Therefore, cold conditions (paraffin) simulation of part Experiment room has only been done in this work, is not ground deeply
Study carefully.In view of at present Treating Methods for BF Slag there are the problem of and Dry granulation of BF slag present Research, must exploitation it is a kind of brand-new
Dry granulation of BF slag and its Exposure degree technology, i.e., grain slag meets the requirement for doing slag cements, and can efficiently return
Receive clinker sensible heat.General thought is to carry out blast furnace Slag treatment and the recoverable present situation of heat with plate-spinning with the air-cooled method being combined
And developing direction.
In recent years, as laterite pyrometallurgical smelting dilval scale progressively expands, smelting ferronickel from red soil nickel ore waste residue（Letter
Claim ferronickel slag）Discharge capacity gradually increase.China's whole year dilval yield is up to 250,000 tons within 2011（Nickel content）, supervene
Solid slag more than 15,000,000 tons, 2015, it is contemplated that the total release of ferronickel slag will be close to 100,000,000 tons, more than copper ashes, manganese slag
Deng the total emission volumn of metallurgical slag, 1/5th of metallurgical slag total release is accounted for.Compared with other metallurgical slags, ferronickel slag is valuable
Metal recovery value is low, and bed drain purge is big, progressively becomes a great problem of metallurgical slag processing.A large amount of electrosmelting ferronickel slags
Bank up and fill, not only land occupation, pollution environment, the sustainable development for returning nickel-iron smelting brings severe challenge.So nickel
Iron smelting industry is badly in need of being that " open circuit " for solving the problems, such as nickel-iron smelting slag carries out the comprehensive utilizating research of scientific system.Nickel-iron smelting
The comprehensive utilizating research of castaway slag, by for innoxious, the recycling of the substantial amounts of nickel-iron smelting castaway slag in the nationwide or even whole world
Processing provides solid foundation.
