Abstract
The invention relates to coal slime and biomass compounded briquette coal. A preparation method of the coal slime and biomass compounded briquette coal comprises the steps of weighing biomass finely particles with the particle size smaller than or equal to 20 millimeters; weighing 100 parts (dry basis) by mass of the coal slime and 10-50 parts (dry basis) by mass of the biomass finely particles to obtain briquette coal raw materials; mixing the briquette coal raw materials uniformly to obtain a mixed briquette coal raw material; pressing the mixed briquette coal raw material into briquette coal products with a certain mechanical strength and shape by using a shaping machine. The compounded briquette coal raw materials also can comprise a proper amount of a combustion-supporting coal-saving agent. Products provided by the invention comprise the coal slime and the biomass. Compared with briquette coal completely prepared by powdered coal, the coal slime and biomass compounded briquette coal provided by the invention can reduce usage amount of non-renewable energy sources and efficiently utilize renewable energy sources. The coal slime and the biomass finely particles are mixed uniformly and pressed into the briquette coal, and when the briquette coal is combusted, the biomass in the briquette coal body is firstly gasified and combusted to generate microporous structures in the briquette coal body, thereby facilitating combustion of the coal slime in the briquette coal body.
Description
Technical field
The present invention relates to a kind of moulded coal and preparation method thereof, particularly a kind of composition of moulded coal.
Background technology
Coal is a kind of fossil oil, and the carbon content of coal is higher, and fugitive constituent is lower, and calorific value is higher, is one of energy of large usage quantity in the national economy.Coal is a kind of non-renewable energy, along with the resource of using coal can be petered out.Coal is in when burning, can produce huge detrimentally affect to our ecotope.Particularly enter the new millennium, Greenhouse effect are increasingly severe, and extreme weather emerges in an endless stream, and environmental pollution continues aggravation.Under this background, demand the coal utilization approach of the friendly type of development environment urgently.
Moulded coal be a kind of take fine coal by main raw material by concrete purposes requirement carry out proportioning, again fine coal is suppressed in forming machine, become the moulded coal goods with certain physical strength and shape.Common moulded coal has briquet, honeycomb briquette and coal briquette etc.At present, in Industrial Boiler, Industrial Stoves and the domestic burners, to belong to the grate firing type stove mostly, when moulded coal burns in the grate firing type stove, in the moulded coal or gapped between the moulded coal, be conducive to burning of coal, compare with burning fine coal, improved burning of coal efficient in larger degree, reduced the pollution to environment.
When mechanical workout compacting moulded coal, the body of moulded coal is pressed very closely knitly, and closely knit body is unfavorable for the burning of moulded coal body.
Agricultural crop straw, wood working waste and hay etc. are the organism of carbon containing, are biomass, can be used as fuel combustion, and the biomass such as agricultural crop straw, wood working waste and hay are a kind of reproducible energy.The biomass of normality are loose, are difficult for transportation, store and use, for convenient transportation, store and use and can biomass in forming machine, be pressed into the biomass solid formed fuel with definite shape with certain pressure.The fugitive constituent of biomass solid formed fuel is higher, and carbon content is lower, and calorific value is not very high.
Coal slime is the by product of discharging during coal separating plant produces, be paste through the coal slime after the filter dehydration, moisture 20%～35%, the particle of coal slime is very thin, and moisture content is high, and retentiveness is strong, be difficult for dry, the mud stickiness is larger, because these characteristics of coal slime have also caused stacking, storage and the transportation of coal slime all relatively more difficult.The coal slime that acts as a fuel is difficult to burn in the grate firing type stove.Coal slime is when storing up, and its form is extremely unstable, meets water and namely runs off, air-dryly namely fly upward, not only wasted valuable coal resources, and caused serious environmental pollution, sometimes even restricted the normal production of coal washery, become comparatively stubborn problem of one of coal separating plant.
In the prior art, coal slime and biomass are not combined and make coal slime and composite biomass briquettes and preparation method thereof.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of coal slime and biomass are combined and make coal slime and composite biomass briquettes and preparation method thereof.
The present invention is achieved using the following method.
Coal slime and composite biomass briquettes are the moulded coal goods with certain physical strength and shape that are pressed into forming machine, the moiety of moulded coal goods has coal slime and biomass, the granularity of biomass is not more than 20 millimeters, the mass parts of coal slime butt is 100, and the mass parts of biomass butt is 10 ~ 500.
The making method of coal slime and composite biomass briquettes has the following steps:
1. get the particle in small, broken bits that granularity is not more than 20 millimeters biomass;
2. get respectively the butt mass parts and be 100 coal slime and butt mass parts and be the particle in small, broken bits of 10 ~ 500 biomass, obtain moulded coal and cooperate raw material;
3. the moulded coal raw material is mixed, obtain the mixed type coal raw material;
4. the mixed type coal raw material is pressed into the moulded coal goods with certain physical strength and shape with forming machine.
Product of the present invention has coal slime and biomass; compare with the moulded coal of all being made by fine coal; reduced the consumption of Nonrenewable energy resources; effectively utilized renewable energy source, after the particle in small, broken bits of coal slime and biomass mixes and is pressed into moulded coal, when burning; the in advance gasification of the intrinsic biomass of moulded coal, burning; after the intrinsic gasifying biomass of moulded coal, the burning, in the moulded coal body, generate microvoid structure, be conducive to the burning of coal slime in the moulded coal body.
Below in conjunction with embodiment, the present invention is further described.
