Description
Technical field
The present invention relates to biomass fuel processing technique field, the preparation side of a kind of biomass solid formed fuel
Method.
Background technology
For a long time, the Fossil fuel such as oil, natural gas, coal is always the main energy sources that the mankind consume, and is the mankind
Economical prosperity, the progress of society and growth in the living standard are made that the biggest contribution.But due to coal, oil and natural gas etc.
Mineral resources are non-renewable, and resource is limited, are faced with the danger petered out.In recent years, the energy, environmental problem
Outstanding day by day, energy prices continuous rise, whole world research and development bioenergy becomes focus.China is a large agricultural country, biological
Mass-energy resource is the abundantest.But the utilization rate of crops leftovers only reaches 20-30%, agricultural waste material there are about half abandon in
Wilderness fails to utilize even burns, and not only can not be comprehensively utilized, and causes the serious waste of resource, and pollutes environment.Biological
The compact formed technology of matter can fully comprehensively utilize plant resources and prepare biomass molding fuel, can effectively alleviate the current energy
Crises problem.
Biomass molding fuel is to utilize compact formed technology that biomass processing becomes easily storage and the convenient life used
Material grains or bar-shaped, patch fuel, have that volume is little, capacity is big, calorific value is high, combusting firepower is prosperous, raw material the most easily takes, can be again
The characteristic such as raw, in combustion process, deslagging is few, flue dust and the advantage such as content of sulfur dioxide is low, environmental pollution is little, is coal and fuel wood
Outstanding alternative fuel.China's introduction of foreign technology eighties in 20th century begins one's study and develops biomass moulding technology, the most
Begin to take shape. through continuous research and development, having been achieved for bigger development, the enterprise of former is researched and produced in the whole nation
Or existing tens of R&D institution.But China's biomass molding fuel there are still bigger problem now, processing technique is complicated, difficult
Degree is big, energy consumption is big, cost is high；Shaped fuel excess-heat value, moisture content and ash are difficult to control to；Shaped fuel holds in combustion
Easily slagging scorification, easy dust stratification, so that fuel combustion is insufficient, not only pollutes environment and has also corroded production equipment；Due to processing system
Grain raw material be high microsteping material, raw material is loose, size and material variation, when grain forming, difficulty is pressed into compact grain
Shape；The rough of molding, various shapes also have impact on sales volume, and what these problems were serious constrains biomass moulding combustion
The large-scale production of material.
Summary of the invention
The problem existed for current biomass preparation of fuel of the present invention, it is provided that a kind of biomass solid formed fuel
Preparation method.The biomass fuel that this method prepares has that density is little, calorific value is high, ash is few, the internal voids of product is little,
The loosest, humidity resistance is good, can the advantage such as preservation for a long time.
In order to realize object above, the technical solution used in the present invention is as follows:
The preparation method of a kind of biomass solid formed fuel, is with weight ratio as 100:5-10:5-10:10-15:3-5:6-
The bagasse of 10:4-8, magnesium oxide, red mud, Kaolin, cerous sulfate, polyvinyl butyral resin glue and bituminous epoxy are former
Material, by pulverizings, molding, the operation such as to be dried prepared, and described method concrete operation step is as follows:
(1) bagasse is added pulverizer and be crushed to 40-60 mesh, obtain bagasse powder；
(2) bagasse powder, magnesium oxide, red mud, Kaolin and cerous sulfate are added agitator, add suitable quantity of water and stir into paste
Shape thing；
(3) taking above-mentioned pastel and put into muffle furnace, at temperature is 700-900 DEG C, roasting 2-3h, obtains carbide；
(4) after carbide being mixed homogeneously with polyvinyl butyral resin glue and bituminous epoxy, the mixed material conveying obtained
To forming machine, being 120-140 DEG C in temperature, pressure is extruded under 60-90Mpa, obtains shaped fuel；
(5) shaped fuel is dried, be cooled to room temperature, packaging, obtain biomass solid formed fuel.
Preferably, the water content of the above bagasse is 10%.
Preferably, above step (2) described stirring is stirring 20-30min under rotating speed is 300-500r/min.
Preferably, the heating rate of above step (3) described roasting is 5-10 DEG C/min.
Preferably, the mass concentration of the above polyvinyl alcohol resin glue is 15%.
Preferably, above step (5) described drying is to be dried to water content at temperature is 80-100 DEG C by shaped fuel
For 5-8%.
Compared with prior art, advantages of the present invention and good effect are:
1, the present invention is using agricultural waste material bagasse as primary raw material, and raw material sources are extensive, cheap, not only comprehensive utilization
With garbage, reduce environmental pollution, it is achieved the sustainable development of resource, moreover it is possible to effectively alleviate current energy crisis and ask
Topic, after solid molding fuel burning simultaneously, charcoal ash can be used as again fertilizer, expands the using value of bagasse.
2, the present invention is by red mud, Kaolin and the common effect of cerous sulfate, it is possible to decrease the burning-point of shaped fuel, improves combustion
The fusing point of material ash, solves easily slagging scorification, easy dust stratification, insufficient the asking of burning in combustion of current biomass shaped fuel
Topic.
3, the present invention adds polyvinyl butyral resin glue and bituminous epoxy in shaped fuel, owing to polyvinyl alcohol contracts
Butyral resin and bituminous epoxy have stronger caking property and adsorptivity, so that the product arrived is fine and close, the loosest, are difficult to tide
Solve, can preserve for a long time, simultaneously can the harmful gas that produces in combustion of adsorbed fuel.
4, the present invention adds magnesium oxide in shaped fuel, can play combustion-supporting effect, make molding in fuel combustion process
The reactivity of fuel is improved, it is possible to reach the effect fully burnt completely；Magnesium oxide plays solid sulfur in combustion
Effect, make sulfur dioxide reaction generate magnesium sulfate, thus reduce the discharge of form waste gas of sulfur dioxide；The most also there is bonding, prevent
Water and the effect of enhancing.
The calorific value of the biomass molding fuel product that 5, prepared by the present invention controls to be 20-23MJ/kg, and content of ashes is 3.2-
4.7%, water absorption rate is 10-12%, and properties is better than current commercial product.
6, the inventive method has that preparation technology is simple, it is low to consume energy, production efficiency is high, ratio of briquetting is high, low cost and other advantages,
Prepare biomass fuel density little, calorific value is high, ash is few, the internal voids of product is little, the loosest, humidity resistance is good, can
Long-term preservation, it is adaptable to industrialized production.
