Abstract
The present invention relates to a solid fuel prepared from fly ash, polyethylene plastics and biological fuel through the processes of heating, mixing, stirring and extrusion forming. Said invention can reutilize about 1-25% of effective heat value of fly ash and inflammable property of biological fuel and waste plastics to change the discarded material into effective new energy source. Said fuel is simple in production process, light in weight, water-resistant, long in combustion time and easy to store, and its raw material cost is low.
Description
The invention belongs to solid fuel, particularly relate to solid fuel of making by waste materials containing carbon and preparation method thereof.
Industrial and civilian waste material such as flyash, plastic waste etc. are one of primary pollution source that causes present environmental pollution.The annual only flyash quantity discharged of power plant in the whole world is about 2 hundreds of millions tons at present, China also reaches more than 4,000 ten thousand tons every year, along with developing rapidly of energy industry, the generation of flyash also can be increasing, existing only have seldom part as cheap stopping composition by owing to make building materials etc., and major part is deposited in the farmland, a large amount of land resourcess have been taken, along with the variation of weather can increase a large amount of suspended substances, Air quality is seriously descended, and cause the pollution and the alkalization of farmland soil property of the surface water.And plastics have premium propertiess such as light weight, intensity height, corrosion-resistant, easy processing, rising along with plastics consumption, as the widespread use of plastic food packing thing, plastic sheeting for farm use etc., its waste because do not dissolve, without putrefaction, to the pollution problem of environment also serious day by day.According to statistics, plastic waste accounts for 70% of plastics output, plastic refuse accounts for the 10-15% of municipal wastes amount, have only 10% to be carried out utilization in China's plastic refuse, 20-30% is burned or landfill, and 60-70 is stacked, abandons arbitrarily or pour into rivers,lakes and seas, not only cause the pollution of environment, simultaneously also be a kind of waste, thereby recovery and Utilization of Waste Plastics is imperative to resource.
The purpose of this invention is to provide a kind of solid fuel that flyash and plastic refuse make for raw material and preparation method thereof that utilizes, its raw material all is to use final waste material or the waste in life and the industrial and agricultural production process, to replace the widely used honeycomb briquette raw material of present China urban and rural residents.
Flyash is a kind of bulk solids aggregation, is spongy and fine particle hollow ball-shape, has very big specific surface area; In addition, flyash is produced after burning by coal, and the wherein still residual combustiblematerials that 1-25% is arranged obtained activation under some surface group high temperature of flyash, so flyash has higher adsorption activity.And plastics itself are to contain high-octane fuel, reclaim heat energy and are worth higher.
The objective of the invention is to realize by the following technical solutions: make full use of the molecule feature of flyash and the incendivity of plastic refuse, promptly use flyash and plastic refuse, and a kind of civil solid fuel of a certain amount of biofuel of corresponding adding (as plant standing grain stem) production.
Solid fuel of the present invention comprises that said flyash is the waste material that fuel-burning power plant, heat power plant and various coal-burning boiler coal burning back produce; Said plastic refuse is depleted convenient bag after life and the industrial and agricultural production, plastic cloth, plastic packing article, the agricultural films such as mulch film that use in various food packs and the agriculture production, and all polyethylene products all can use; Said biofuel mainly is a combustiblesubstance in forest or agricultural-food and the waste thereof, cuts and offal, crop stalk, fruit shell, skin, leaf and rhizome etc. as the sheet of bark, timber.
