Abstract
The present invention has introduced the inorganics binding agent and the moulding process thereof of a kind of formed coke (coal).This binding agent contains Al
2O
3Breeze and the mixture of water glass solution, also can be the mixture that bauxite chamotte adds soft clay and water glass solution, its proportioning be: burnt (coal) powder: bauxite chamotte: soft clay: water glass solution=100: (6～8): (6～8): (10～15).The present invention has the advantages that the binding agent resource is wide, price is low, cohesive force is strong, formed coke (coal) cold strength height, water-tolerant, and moulding process is simple, self-vulcanizing, need not oven dry, save advantages such as the energy.
Description
The invention belongs to the forming technique of coke breeze (coal), more properly say, relate to a kind of formed coke (coal) and moulding process thereof of making binding agent with inorganics.
The external used binding agent of formed coke (coal) moulding, in the majority with coal tar, pitch person.But because coal-tar pitch output is limited and carcinogenic substance is arranged, so upgrading petroleum pitch, high molecular polymer, industrial effluent have also been developed in recent years, inorganics can inorganic-organism compound binding agent.
Day disclosure special permission bulletin: 82.135.893 discloses the coal briquette for civillan use of Japanese Matsushita Electric Industrial industrial with mineral binder bond, is by 70% coal, 12% aluminium cement, 12%CaCO
3, 6%K
2CO
3Prescription make, the composition of its aluminium cement preferably contains CaO30～60%, AL
2O
340～60%, Fe
2O
32～10%, can also add Ca(OH)
2, CaCO
3, Na
2CO
3, K
2CO
3, MgO, ZnO etc. are as sulphur-fixing agent.This briquette binder addition is big, increase ash content, and composition is more, makes complexity, and cost is higher.
The 86101384A of Patent Office of the People's Republic of China discloses " briquette binder " of Taiyuan chemical rubber institute, be to form by polyvinyl alcohol and formaldehyde condensation polymer, addition in coal is 3～7%, this briquette binder belongs to organic compound, price is more expensive, and the moulded coal hot strength of making is not high, can not satisfy service requirements, therefore never is applied.
In sum, do not find the industry and civilian formed coke (coal) binding agent of a practicality at present as yet.
The object of the present invention is to provide a kind of resource extensive, cheap, be easy to make, cohesive force is strong, the formed coke of making (coal) cold strength height, water-fast, and less binding agent and the technology thereof of ash content is made formed coke (coal).
Formed coke of the present invention (coal) is made up of burnt (coal) powder and binding agent, it is characterized in that binding agent is by containing AL
2O
3Breeze and sodium silicate solution form the proportion of composing of burnt (coal) powder and binding agent: burnt (coal) powder: AL
2O
3Breeze: sodium silicate solution=100: (12～16): (10～15).
AL
2O
3Breeze can add soft clay with bauxite chamotte and replace its proportioning: bauxite chamotte: soft clay=1: 1.
Bauxite chamotte can be to contain AL
2O
3At the Industrial products more than 80%, soft clay can be to contain AL
2O
3At the Industrial products below 30%, the modulus of water glass is more than 3.0, and optimum value is 3.2.
Moulding process of the present invention is:
(1) burnt (coal) crushing screening, powder requires between 8～0.5 millimeters,
(2) adding earlier contains AL in burnt (coal) powder
2O
3Breeze (or bauxite chamotte+soft clay),
(3) add sodium silicate solution again after mixing,
(4) stir discharging in 5～10 minutes,
(5) left alone without helply under the room temperature stay 5～10 minutes,
(6) put into the shaper extrusion forming,
(7) left alone without helply under the room temperature put curing in 6 hours.
Moulding process also can change into: use AL earlier
2O
3Breeze (or bauxite chamotte+soft clay), water glass solution is made binding agent, pours into then in Jiao's (coal) powder and mixes, and makes formed coke (coal) by above-mentioned (four)～(sevens') process again.
The present invention has the following advantages:
1. the formed coke of making (coal) solidifies under the room temperature, the cold strength height, and water-tolerant is not no matter long-distance transport or outdoor storage can be pulverized; Along with the raising of temperature, intensity increases, and can satisfy service requirements under the condition of high temperature.
2. solidify under the formed coke of making (coal) room temperature, do not need oven dry can save a large amount of energy, itself does not burn mineral binder bond, and consume fuel does not increase volatile matter and sulphur content.
3. the main raw material of binding agent source is abundant, low price, and therefore, the formed coke of producing (coal) cost is lower.
4. moulding process is simple, need not heating, processing ease.
Embodiment:
Example 1: the Shanxi coke powder sieves, get 6～2 millimeters 1300 parts, add bauxite chamotte (industrial first grade) 90 parts, 90 parts of soft claies (industrial first grade) mix in sand mill, 180 parts of the sodium silicate solutions of adding 3,2 moduluses, stirred discharging, at room temperature left alone without help putting 8 minutes 5 minutes, put into the shaper pressurization, self-vulcanizing.The index that reaches: intensity (M
40)＞75%.
Example 2: the Shanxi coke powder sieves, and gets 8～0.5mm1250 part, adds 180 parts in Henan bauxitic clay powder, stirs in the sand mill, add 190 parts of 3.2 modulus water glass solutions, mixed discharging 7 minutes, room temperature is left alone without help put 10 minutes, went into the shaper compacting, self-vulcanizing.
The performance index that reach: intensity (M
40)＞75%
Example 3: get 90 parts of bauxite chamottes (industrial select quality), 90 parts of soft claies (industrial first grade), 180 parts of water glass solutions that add 3.2 moduluses, stir made binding agent in 5 minutes after, pour into and mix 5 minutes, discharging in 1400 parts 6～2 millimeters the Shanxi coke powder, at room temperature left alone without help putting 5 minutes gone into the shaper extrusion forming, self-vulcanizing.
