Abstract
The invention discloses a method for manufacturing a green solid fuel by using a biomass mixed material, and belongs to the technical field of solid fuels manufactured by using biomass. The method comprises the following steps of: crushing, adding, heating, cooling and extruding, namely crushing the biomass mixed material into granules of which average diameter is 10 to 30 millimeters, adding 5 to 20 mass percent of water, 5 to 30 mass percent of pulverized coal, 1 to 3 mass percent of calcined lime and 5 to 10 mass percent of sodium carboxymethylcellulose into the granules, heating for 1 to 3 hours with stirring at the temperature of between 150 and 250 DEG C, cooling the mixture at the cooling rate of 20 to 30 DEG C per minute, and finally extruding the mixture into the solid fuel. The method has the advantages that: many mixtures such as straw biomass, waste plastic, urban organic solid wastes and the like are used as raw materials for low heat treatment, and the green solid fuel with high specific weight, high density and high calorific value is finally manufactured by synergy of the substances; and the green solid fuel is convenient to store, transport and continuously use.
Description
Technical field
The present invention relates to a kind of method of utilizing the biomass mixture material to make green solid fuel; Relate in particular to a kind of method of utilizing mixture manufacturings such as stalk biomass, agricultural timber waste, waste or used plastics, city organic solid castoff than the high heating value green solid fuel great, that density is big, belong to biomass and make solid-fuelled technical field.
Background technology
In recent years, the whole world is growing to demands for energy, and as the fossil oil of the main source of the energy in rapid minimizing, therefore seek the focus that a kind of reproducible substitute energy has become social common concern.
China's biomass produce enormous amount; Annual waste such as stalk biomass, agricultural timber waste is serious, and the annual generation of plastic refuse surpasses 1,200 ten thousand tons, and the quantity of organic solid castoff increases severely year by year in the city; But they distribute and comparatively disperse; Energy density is little, and transportation, processing are all very difficult, and cost is high.Have higher energy utilization and be worth organic solid useless mainly be made up of carbon, protium, do not filled energy dissipation, environmental pollution and the social concern that utilization brings because of these biomass and become increasingly conspicuous but China is annual.
At present, because the biomass material kind is numerous, all kinds of physics-chem characteristic difference are very big; No matter be the heat energy that utilizes burning to produce, the energy that still utilizes pyrolysis, gasification to produce all exists raw materials pretreatment difficult; Problems such as equipment is low to all scope biomass undergoes adaptations, and utilising efficiency is low.For example: the boiler and the device of burning, gasification stalk biomass are not high to burning, the gasification efficiency of some forestry excess, and stability is bad, can not effectively dispose materials such as urban waste plastics equally.Therefore, need seek a kind of method of the mixed biologic of processing and utilizing efficiently raw material, to obtain more substitute energy.
Summary of the invention
