Description
Technical field
The present invention relates to a kind ofly be used to fire clay brick or be directly used in fuel for brick baking/boiler of boiler and preparation method thereof.
Background technology
Come from the coal mining of China at present its interests are discarded in the coal gangue in the recovery process as refuse outside, be not fully used, not only taken the soil, also polluted environment, this is a problem of failing to obtain fine solution over a long time.
Remove this, the cereal wine slag of common tailing, husk and brewery as stalk, wood sawdust, timber or bamboo processing industry, the Chinese medicine slag in pharmaceutical factory etc. in people's daily life, though someone wants these " refuse " used, but because the restriction of condition, major part still abandons as refuse, be not utilized effectively, especially they be used as fuel in firing clay brick or directly yet there are no relevant report as boiler oil.
Summary of the invention
The object of the present invention is to provide a kind of coal gangue and stalk or wood sawdust or husk, cereal wine slag or Chinese medicine slag etc. of utilizing to be used to fire clay brick with fuel or directly as the fuel of civil boiler, remove this present invention a kind of method for preparing this fuel also is provided as feedstock production.
For achieving the above object, the technical solution used in the present invention is: described fuel for brick baking/boiler is made up of coal gangue, vegetable active carbon, and coal gangue accounts for 85～98% of gross weight, and vegetable active carbon accounts for 2～15% of gross weight, wherein:
Coal gangue is selected from: the coal gangue in natural bituminous coal or the hard coal.
Vegetable active carbon is selected from: a kind of in stalk, wood sawdust, husk, wooden bamboo wood tailing, cereal wine slag, the Chinese medicine slag carbide.
The surface-moisture of coal gangue is removed, be broken into 0～3mm grade, put in storage stand-by.
With stalk, wood sawdust, husk, wooden bamboo wood tailing, cereal wine slag, Chinese medicine slag classification, dry to moisture and be lower than 5%, be classified into the carbonization chamber, carbonization becomes vegetable active carbon under normal pressure, and screening is being broken into 0～3mm greater than the vegetable active carbon more than the 5mm, class wrapping is put in storage stand-by.
A kind of mixing and stirring of carrying out in coal gangue and the vegetable active carbon is become described fuel for brick baking/boiler, be called comprehensive coal.
The fuel for brick baking/boiler that adopts as above technical scheme to provide compared with prior art can obtain following effective effect:
1. the starting material of Shi Yonging are coal gangue that goes out of use and stalk, wood sawdust, husk, wooden bamboo wood tailing, Chinese medicine slag, the cereal wine slag that also is underutilized, utilized advantage separately, overcome shortcoming separately, reduced dependence to limited resources (raw coal), become the bright spot of recycling economy, have great environmental benefit.
2. the clay brick (common brick) that utilizes a kind of comprehensive coal that mixes in coal gangue and the vegetable active carbon to fire, ultimate compression strength reaches 11.1～13.4MPa, is up to state standards, and destructive load reaches 160～190KN, satisfies the design strength class requirement.
3. to an enterprise that produces 100～1,500,000 blocks of clay bricks per year, annual savable fuel consumption charge is 3～50,000 yuan.
If 4. with vegetable active carbon and natural coal facies grating, the result of use of the comprehensive coal of gained is better.
Embodiment
Below in conjunction with embodiment the specific embodiment of the present invention is described in further detail.
Described fuel for brick baking/boiler is that each component percentage composition sum is 100 in the said composition by the coal gangue that accounts for gross weight 85～98%, the vegetable active carbon combination that accounts for gross weight 2～15%, wherein:
Coal gangue is selected from: natural bituminous coal coal gangue or hard coal coal gangue, the best are selected from the bituminous coal coal gangue after coal washing.
Vegetable active carbon is selected from: a kind of in the carbide of stalk, wood sawdust, husk, wooden bamboo wood tailing, cereal wine slag, Chinese medicine slag.
Coal gangue is dried the removal surface-moisture, become 0～3mm grade, packed for standby use with crusher in crushing.
Stalk, wood sawdust, husk, wooden bamboo wood tailing, cereal wine slag, Chinese medicine slag dried respectively to moisture be lower than 5%, the carbonization chamber is sent in classification, under condition of normal pressure, become carbide, promptly make vegetable active carbon, screening, vegetable active carbon greater than the 5mm grade is crushed to 0～3mm grade respectively, class wrapping, the warehouse-in stand-by.Resulting vegetable active carbon, carbon content greater than 80%, sulphur content≤0.05%, volatile matter≤29.5%, calorific value reaches 19.12 * 10
6J/kg belongs to the higher calorific value activated carbon, and wherein said carbonization chamber is a prior art.
Become comprehensive coal with the coal gangue that accounts for gross weight 85～98%, a kind of mixing and stirring of accounting in the vegetable active carbon of gross weight 2～15%, be described fuel for brick baking/boiler, long-pending big, little, inflammable, the anti-burning of density of this comprehensive coal body.With described fuel for brick baking/boiler and clay mixed routinely, be shaped to 240 * 120 * 60 base, the sign indicating number heap dries at 1300～1400 ℃ and becomes 215 * 115 * 55 clay brick after burning 40～48h, and its performance meets design requirement.For example with 1 ton of comprehensive coal fire 3000 surplus block clay brick, the ultimate compression strength of brick is 11.0～13.4MPa, collapsing load is 160～190KN, and surfacing, the quick-fried strong phenomenon of no concave-convex.The production cost of brick is than hanging down 15～20% with raw coal, weight saving about 5%.
