Abstract
The high-efficiency briquette is made up by using coal and natural high-molecular binding agent as main materials. As compared with the existent briquette made of yellow clay etc., can be fully burned, and its heating power is high, burning time is long, and residual cinder is less, so that it can reduce contamination from coal ash and dust to environment. ADVANTAGE-. the production method is simple, applicable to medium-grade and low-grade coal.
Description
The present invention relates to a kind of moulded coal and manufacture method thereof.Belong to solid-fuelled improvement.
Domestic commercially available honeycomb briquette has two big classes at present:
The one, with the yellow mud binding agent, general consumption is more than 30%, and there is following deficiency in this coal:
1, yellow mud itself will consume partly heat energy during coal combustion, the waste energy, and thermo-efficiency is low;
2, the coal proportion is lower, and combustion time is short, thermal value is low;
3, coal burning-point height is difficult for lighting, and the user uses inconvenience;
4, the coal after-flame make the grey quantity of slag many, become one of municipal wastes main source.Cause very big pressure for refuse collection, transportation, the processing in city.
The 2nd, do not add patented product 888 flame god (high-effect moulding coal and the manufacture method thereof of yellow mud, the patent No.: 921131267) replaced partly yellow mud honeycomb briquette, this coal is compared with yellow peat, and it is abundant to have a coal combustion, advantages such as thermal value height, combustion time are long, and the recrement amount is few.But still there is following deficiency in this coal:
1, this coal is binding agent with the water glass, not only can not burn, and also fire-retardant, consume heat energy, wasted partly heat energy;
2, because water glass is fire-retardant, improved the burning-point of coal;
3, behind this coal combustion, lime-ash is loose powder, and fire tongs can not press from both sides when changing coal, causes serious dust polluting environment.The user uses inconvenience;
4, fire-retardant owing to water glass, consumption is restricted, and the easy moisture absorption decomposition of water glass, has influenced the intensity of moulded coal, is not easy to store and transportation;
5, this patented technology is confined to the application of some fat coal, can't use low and middle-grade coals.
The external existing multiple moulded coal made from cleaned coal, this coal is with fine coal powder, and charcoal and plant adhesive are made.Burning-point is low, easily lights, and combustion time is long, but complex manufacturing technology costs an arm and a leg, and does not meet the resource reality and the present level of consumption of China, can not extensively enter the daily use of family.
The object of the present invention is to provide a kind of shortcoming that overcomes above-mentioned all kinds of moulded coal.Fundamentally change the fire-retardant disadvantage of coal briquette bond power consumption, use the combustion-supporting tackiness agent that can burn, thereby realization heat height, easily light, combustion time is long, and is easy to use, and raw material is obtained easily, the highly-effective shaped coal good for environment protection and the manufacture method thereof of free from dust pollution.
The present invention is made up of coal, combustion-promoting adhesive, and wherein combustion-promoting adhesive is not by one or more the grey black toners formed in one or more and oxyhydroxide or the carbonate in macromolecular compound weathered coal, brown coal, the coal gangue.Its proportion is 10%～30% of a gross weight, and all the other are coal.The present invention is a tackiness agent owing to having used weathered coal, its adhesion characteristic is by humic acids in the weathered coal and the cotton-shaped gelinite of humate, coal dust is bonded to meets the water stability crumb structure that water is difficult for scattering, make loose small air gap is arranged in the moulded coal body, help replenish air and go into coal body, coal is fully burnt, and coal body does not scatter during burning.Humic acids is that a kind of macromolecular compound has ion-exchange and complexation property, can form mixture with the mineral in the coal, reduces ash melting point, makes lime-ash have cohesiveness, presss from both sides out from stove thereby can become whole.Final product after the polymer burning is a water, and water at high temperature resolves into hydrogen and oxygen, and the hydrogen burning oxygen and aiding combustion produces bigger heat, thereby realizes purpose of the present invention.
Above-mentioned coal comprises the high-quality and the middle inferior coal of bituminous coal, hard coal and bone coal.If family uses, generally select the above hard coal of 4500 kilocalories for use.If industry is used, three kinds of coals can.The present invention looks purposes can make various forms of moulded coals such as lump coal, ball coal, honeycomb briquette.In addition, above-mentioned coal particle size is generally more than 10 orders, and 40～60 orders are good.
Above-mentioned combustion-promoting adhesive add-on with moderate be good, but the coal dust that (is lower than lower limit) very little bonding is not enough, has both influenced the intensity of moulded coal, can scatter as making the too loose not anti-burning of coal body too much by nature during burning.Tackiness agent is relevant with itself quality humic acids content and coal quality, should be determined on a case-by-case basis, and does not generally scatter when being bonded to burning, can form whole lime-ash body after the burning and press from both sides out in the stove and be standard.According to the coal situation, add and put 10%-35% and be advisable.
Some regional weathered coal, brown coal, the humic acids content in the coal gangue is lower, does not reach the agglutinating effect, especially do not reach the reduction ash melting point, make lime-ash be bonded to integral body and press from both sides out, improve humic acids content in the raw material, reach bond effect thereby then can adopt oxidation style to generate the regeneration humic acids.Oxygenant can adopt also available air oxidation of nitric acid.
Manufacture method of the present invention is as follows: with coal, weathered coal or brown coal, the combustion-promoting adhesive that coal gangue is made is a major ingredient.At first weathered coal is ground into 40～60 purpose fineness, (5～6% the water that adds gross weight, 0.3～0.4% sodium hydroxide) then in the weathered coal that sodium hydroxide injection soluble in water is pulverized, and stirs, and is combustion-promoting adhesive.Again combustion-promoting adhesive is admixed in the raw coal, (its proportioning be preceding described, be determined on a case-by-case basis), and stir, add 10～12% clear water then and be crushed to 40～60 purpose fineness, with the coal charge moulding of pulverizing, just be readymade coal after drying at last.
Above-mentioned tackiness agent and coal add the water process, decide on the raw material humidity, if feed coal, weathered coal is done then need add water, otherwise then adds water less.
The present invention compared with prior art has following advantage:
1, tackiness agent can burn and be combustion-supporting, emit heat, has fundamentally changed the shortcoming of clay, the fire-retardant power consumption of water glass.
2, because tackiness agent can burn, reduced the moulded coal burning-point, moulded coal is easier lights than yellow peat and 888 flames god.
3, the lime-ash after the burning is bonded to integral body, can press from both sides out the free from dust contaminate environment with fire tongs is whole in stove when changing coal.
4, because the adhesion characteristic of weathered coal makes moulded coal that loose coal body be arranged, stable crumb structure is arranged, fine hole is arranged, coal is fully burnt.Thermal value is big, and combustion time is long.
5, because coal body is loose, increase the ton coal and produced moulded coal quantity, saved coal, increased economic benefit.
6, the cinder amount is than the relative minimizing 50% of yellow peat.
7, moulded coal has bigger intensity, is convenient to transportation and storage.
8, do not strive the soil, help ecological environmental protection with agricultural.
9, be in, inferior coal do not add the application that clay is made moulded coal, opened up new approach.
The present invention has advantages such as energy-conservation, sufficient combustion, thermal value height, non-environmental-pollution, nontoxic, free from extraneous odour, recrement amount are few in sum, extensively is fit to occasions such as family, hotel, wineshop, tourist spot and does daily cooking, heating, picnic, makes limit stove etc.
