Abstract
The invention relates to a composition for preparing coal briquette. The composition comprises blind coal, coke powder, glutinous rice flour and sodium chloride. The coal briquette prepared from the composition has a fairly ideal calorific value, and does not cause pollution on the environment, and especially, coal slime is added to the composition, so that the surface of the coal briquette is smooth; the coal briquette is not easily crushed; and a certain amount of pulverized coal is generated even if the coal briquette bears large friction force, so that waste of resources can be avoided.
Description
Technical field
The present invention relates to a kind of for the composition of making moulded coal.
Background technology
Traditional moulded coal mixes back compression moulding by clay and lime usually, though this kind coal briquette can be made moulded coal with fine coal, its calorific value and intensity are relatively low, and can slagging scorification after the burning, thereby influences the coal-fired stove trouble-free burning easily.For this reason, Chinese patent 1891797A number open name is called " tempered anchracite ball " proposition a solution.This coal briquette adopts hard coal and low sulphur coal, and mold strengthening agent, and mold strengthening agent wherein is made of cement.Though its coal briquette that proposes can solve intensity and hardness is low, and calorific value is high and burning after problem such as not slagging scorification, but because cement is a kind of incombustible material, if cement content is low excessively, can not improve intensity and the hardness of coal briquette, if cement content is too high, can reduce the calorific value of coal briquette, for this reason, it is that the above hard coal of 6000 kilocalories is as raw material that this kind coal briquette adopts calorific value, and the hard coal that calorific value surpasses 5000 kilocalories cost height not only, and also difficulty relatively of raw material sources.
Chinese patent 1106059A number disclosed name is called " moulded coal synergistic agent and include moulded coal of this synergistic agent and preparation method thereof " and provides a kind of moulded coal synergistic agent that utilizes pro-oxygenic agent, catalyzer, scavenging agent and additive to make, and what additive wherein adopted is sodium-chlor.Because the sodium-chlor heating temperature can dissolve when reaching 804 ℃, and heating temperature can gasify when reaching 1439 ℃, so, add sodium-chlor in the moulded coal and can increase air and combustion time in the coal-fired stove.But because the synergistic agent content that increases in this moulded coal is less, and the content of sodium-chlor is not high yet in the synergistic agent, so the moulded coal that utilizes this kind synergistic agent to make also is difficult to reach ideal effect; Simultaneously because also comprising pro-oxygenic agent, catalyzer and scavenging agent in the synergistic agent, except the cost of making moulded coal is higher relatively, and the intensity of moulded coal and hardness also differ and reach better program surely.
In addition, Chinese patent 1115781A number disclosed this coal briquette that is called " a kind of high-energy convenient life coal briquette " proposition is to be made of high-quality anthracite powder, sodium oleate, coke powder, iron carbide, sulfur flour, paraffin wax, solid alcohol, pin acid potassium, red phosphorus, ferric oxide, cupric oxide and sticky rice flour, and sticky rice flour mass content wherein is 3%.Though this kind coal briquette very easily burns, but owing to contain various chemical components such as a certain amount of sodium oleate, sulfur flour, paraffin wax, pin acid potassium, red phosphorus, ferric oxide, cupric oxide in this coal briquette, and the content of this binding agent of sticky rice flour is less relatively, so, intensity and the hardness of this coal briquette are relatively low, and burning the time can pollute environment.For addressing the above problem, it is the moulded coal that adopts coal dust and binding agent to make that Chinese patent 1931977A number disclosed name is called " a kind of moulded coal and preparation method thereof ", and the ratio of coal dust and binding agent is 100:20-25, and binding agent wherein is sticky rice powder or millet flour.Though the quantity of the binding agent that adds can make coal dust reinforce moulding, because this kind binding agent can not improve the calorific value of coal dust, and also can be not combustion-supporting, so, use this binding agent of sticky rice powder or millet flour can not increase the technique effect of moulded coal merely; Another problem is, if moulded coal is rough, stack and the process of transportation in, easily produce powder in the mobile process between the contacted moulded coal, thereby cause the wasting of resources and environment is polluted.
Summary of the invention
The purpose of this invention is to provide a kind of mode of selecting suitable material of utilizing and come to solve environmental pollution and the wasting of resources, and the composition of the making moulded coal of problem such as calorific value is low.
The composition of making moulded coal proposed by the invention comprises the material of following mass percent: hard coal 45-70%, coke powder 10-30%, sticky rice flour 10-18%, sodium-chlor 2-8%.
Also be added with the coal slime that mass percent is 5--15% in the described composition.The material that in the described composition by following mass percent is constitutes: hard coal 45-60%, coke powder 10-20%, sticky rice flour 13-15%, sodium-chlor 2-8%, coal slime 5--15%.
Described anthracitic calorific value is more than or equal to 5000 kilocalories.
Coke powder in the composition of making moulded coal proposed by the invention can improve the calorific value of moulded coal; Sticky rice flour is binding agent, can make coal dust reinforce moulding, can not pollute environment; Sodium-chlor can increase gas and the combustion time in the coal furnace, so the moulded coal that utilizes said composition to make has quite desirable calorific value, and can not cause the pollution to environment; Particularly add coal slime in the composition, make the surface of moulded coal very smooth, even if moulded coal is subjected to bigger friction, also is difficult for broken and a certain amount of coal dust of generation with moulded coal, thereby can avoids the wasting of resources.
