Abstract
The invention discloses roasted coal. The roasted coal is prepared from the following raw materials in parts by weight: 80-95 parts of white coal, 3-5 parts of a binder, 2-8 parts of a desulfurizer and 4-6 parts of plant fibers, wherein the binder comprises 280-320 parts of kaolin, 85-105 parts of humic acid, 295-310 parts of bentonite, 80-100 parts of corn starch; the desulfurizer comprises 20-30 parts of hexamethylene tetramine, 45-55 parts of sodium nitrate, 45-55 parts of potassium nitrate, 20-30 parts of potassium permanganate, 20-30 parts of industrial salts, 45-55 parts of industrial essence, 8-12 parts of quick lime and 8-12 parts of sodium hydroxide. The roasted coal adopts the desulfurizer with different components and proportions, and the desulfurizer is combined with the white coal by virtue of the binder to prepare the roasted coal. The sulfur content of the obtained roasted coal is 0.5, which is about 2/5 that of the white coal, so that when the roasted coal is combusted, the exhausted sulfur dioxide is greatly lowered to meet the environment-friendly idea. The invention further discloses a preparation method of the roasted coal.
Description
Technical field
The present invention relates to energy field, particularly relate to environmental protection and to warm oneself by a fire coal and preparation method thereof.
Background technology
Along with people are to the more and more attention of environment, warm oneself by a fire coal also towards the future development of environmental protection.Usually, coal of warming oneself by a fire is carbonized coal or carbonization rod, and in this carbonized coal or carbonization rod, sulphur content is too high, can produce a large amount of sulfur dioxide gas, not meeting the theory of environmental protection when burning.
Summary of the invention
Based on this, be necessary to provide the low environmental protection of a kind of sulphur content to warm oneself by a fire coal and preparation method thereof.

Above-mentioned environmental protection is warmed oneself by a fire coal, and by adopting the sweetening agent of heterogeneity and proportioning, and adopt binding agent sweetening agent and anthracite to be bonded together, prepare coal of warming oneself by a fire, vegetable fibre can increase the gap between coal, and the coal of warming oneself by a fire obtained more easily is burnt.The sulfur of the coal of warming oneself by a fire obtained is 0.5, is about 2/5 of anthracite sulfur, and make above-mentioned coal of warming oneself by a fire when burning, the sulfurous gas of discharge significantly reduces, and meets environmental protection concept.Warm oneself by a fire preparation method's step of coal of above-mentioned preparation is few, and technical process is simple, reduces the production cost of coal of warming oneself by a fire.
Accompanying drawing explanation
Fig. 1 is that the environmental protection of an embodiment is warmed oneself by a fire the schema of preparation method of coal.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar improvement when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.
The coal of warming oneself by a fire of one embodiment, by weight, is prepared by following raw material:
Anthracite 80-95 part, binding agent 3-6 part, sweetening agent 2-8 part, vegetable fibre 4-6 part.
Wherein, binding agent is for increasing the intensity between anthracite and sweetening agent, and the effect of vegetable fibre increases the gap between coal, more easily burns.Vegetable fibre can select the herbaceous stem of ramie, hemp or jute.In present embodiment, binding agent comprises: kaolin 280-320 part, humic acids 85-105 part, wilkinite 295-310 part, W-Gum 80-100 part.
Sweetening agent refers to and removes free sulphur in anthracite or sulphur compound.In the present embodiment, described sweetening agent comprises: hexamethylenetetramine 20-30 part, SODIUMNITRATE 45-55 part, saltpetre 45-55 part, potassium permanganate 20-30 part, Industrial Salt 20-30 part, industrial essence 45-55 part, unslaked lime 8-12 part, sodium hydroxide 8-12 part.
Above-mentioned coal of warming oneself by a fire, by adopting the sweetening agent of heterogeneity and proportioning, and adopting binding agent sweetening agent and anthracite to be bonded together, preparing coal of warming oneself by a fire.The sulfur of the coal of warming oneself by a fire obtained is 0.5, is about 2/5 of anthracite sulfur, and make above-mentioned coal of warming oneself by a fire when burning, the sulfurous gas of discharge significantly reduces, and meets environmental protection concept.
The preparation method of above-mentioned coal of warming oneself by a fire, comprises the following steps:
Step S110, pulverizes anthracite and binding agent, gets 50-70 object anthracite 80-95 weight part, the binding agent of 3-6 weight part, stir, add sweetening agent and 4-6 part vegetable fibre of 2-8 weight part, pickle 15-24 hour, again stir, extrusion molding, obtain coal rod.
Wherein, in process anthracite and binding agent pulverized, if it is too large to pulverize the particle obtained, the cohesive strength of coal of warming oneself by a fire can be affected; And as too little in fruit granule, when coal of warming oneself by a fire is shaping, be difficult to shaping in the process of extrusion molding, affect the intensity of coal of warming oneself by a fire.Therefore, the order number controlling particle is 50-70 order.
Allow the abundant absorbent binder agent of anthracite and sweetening agent by the object that anthracite, binding agent and sweetening agent are pickled.In the present embodiment, pile up after said components being stirred and pickle.
Anthracite, binding agent, sweetening agent and vegetable fibre are being pickled, after stirring, also have the step of extrusion molding, concrete operations are: adopt machine for producing coal bars press to be squeezed into quincunx or many rhombuses.
Step S120, toasts coal rod 24 hours, obtains coal of warming oneself by a fire at 400-500 DEG C.Wherein, the object of baking is sizing, removes unnecessary moisture content.
