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 composition for making moulded coal.
Background technology
compression moulding after traditional moulded coal is mixed by clay and lime usually, although fine coal can be made moulded coal by this kind of coal briquette, its calorific value and intensity relatively low, and can slagging scorification after burning, thus easily affect coal-fired stove trouble-free burning.For this reason, the open name of No. 1891797A, Chinese patent is called that " tempered anchracite ball " proposes a solution.This coal briquette adopts hard coal and low sulphur coal, and mold strengthening agent, and mold strengthening agent is wherein made up of cement.Although its coal briquette proposed can solve intensity and hardness is low, and calorific value is high and the problem such as not slagging scorification after burning, but because cement is a kind of incombustible material, if cement content is too low, intensity and the hardness of coal briquette can not be improved, if cement content is too high, can reduce the calorific value of coal briquette, for this reason, this kind of coal briquette adopts calorific value to be that the hard coal of more than 6000 kilocalories is as raw material, and calorific value is more than the hard coal of 5000 kilocalories, and not only cost is high, and raw material sources also relative difficulty.
name disclosed in No. 1106059A, Chinese patent is called, and " moulded coal synergistic agent and the moulded coal including this synergistic agent and preparation method thereof " provides a kind of moulded coal synergistic agent utilizing pro-oxygenic agent, catalyzer, scavenging agent and additive to make, and what additive wherein adopted is sodium-chlor.Owing to can dissolve when sodium-chlor heating temperature reaches 804 DEG C, and can gasify when heating temperature reaches 1439 DEG C, so, add sodium-chlor in moulded coal and can increase air in coal-fired stove and combustion time.But because the synergistic agent content increased in this moulded coal is less, and the content of sodium-chlor is not high yet in synergistic agent, so the moulded coal utilizing this kind of synergistic agent to make also is difficult to reach ideal effect; Simultaneously because also comprising pro-oxygenic agent, catalyzer and scavenging agent in synergistic agent, except the cost of making moulded coal is relatively high, and the intensity of moulded coal and hardness also differ and reach better program surely.
in addition, name disclosed in No. 1115781A, Chinese patent is called that this coal briquette that " a kind of high-energy convenient life coal briquette " proposes is made up 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 is wherein 3%.Although this kind of coal briquette very easily burns, but owing to containing the 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 relatively less, so, intensity and the hardness of this coal briquette are relatively low, and can to environment during burning.For solving the problem, name disclosed in No. 1931977A, Chinese patent is called that " a kind of moulded coal and preparation method thereof " is the moulded coal adopting coal dust and binding agent to make, and the ratio of coal dust and binding agent is 100:20-25, binding agent is wherein sticky rice powder or millet flour.Although it is shaping that the quantity of the binding agent added can make coal dust reinforce, because this kind of binding agent can not improve the calorific value of coal dust, and also can not be combustion-supporting, so, the simple technique effect using sticky rice powder or this binding agent of millet flour can not increase moulded coal; Another problem is, if moulded coal is rough, stack and transport process in, easily produce powder in the process of movement between the moulded coal contacted, thus cause the wasting of resources and to environment.
Summary of the invention
the object of this invention is to provide a kind of utilization selects the mode of suitable material to come to solve environmental pollution and the wasting of resources, and the composition of the making moulded coal of the problem such as calorific value is low.
the material that the composition of making moulded coal proposed by the invention by following mass percent is is formed: 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, coal dust can be made to reinforce shaping, can not pollute environment; Sodium-chlor can increase gas in coal furnace and combustion time, so the moulded coal utilizing said composition to make has quite desirable calorific value, and can not cause the pollution to environment; Particularly add coal slime in composition, make the surperficial unusual light of moulded coal, even if moulded coal is subject to larger friction, also not easily by moulded coal fragmentation and a certain amount of coal dust of generation, thus can the wasting of resources be avoided.
