Abstract
The invention discloses a biomass densely formed fuel, which is prepared by mixing corn straw and corncobs according to a mixing ratio of 90:10, or 80:20, or 70:30 or 60:40 or 50:50. The processing method comprises: firstly, drying the corn straw and corncob naturally to reduce water content to less than 15 percent; secondly, grinding the corn straw and corncobs into grains with a grain size of less than 4mm respectively; and finally, mixing raw materials, granulating, naturally cooling, sieving, packaging and manufacturing the biomass densely formed fuel. The biomass densely formed fuel is energy-saving and environment-friendly and can generate a large amount of heat, byproducts such as slag generated after the biomass densely formed fuel is burnt can be used as fertilizer and building materials, so high economic, social and environmental benefit is created.
Description
Technical field the invention belongs to the biomass energy source domain, is specifically related to a kind of biomass compact forming fuel.
The three big main energy sources that the background technology mankind nowadays is used are oil, Sweet natural gas and coal, and they all are the non-renewable energy.According to scholarly forecast, if by the demand of Economic Development speed to the energy, these three kinds of energy will will exhaust in 40 years, 60 years and 200 years respectively.Therefore, utilize bioenergy to substitute the main flow that Nonrenewable energy resources have become world today's energy field development.In recent years, the bioenergy technology had obtained the development of advancing by leaps and bounds, but simultaneously, some shortcomings of bioenergy also manifest gradually.First-generation bioenergy mainly uses fruit, replaces diesel oil such as the grease that utilizes plants such as olive, soybean, sunflower, rape, numb maple, perhaps utilizes plants such as corn, sugarcane, Ipomoea batatas to refine ethanol.Though the energy that this mode is refined belongs to renewable energy source, and safety and environmental protection, will cause grain and edible oil crisis owing to rely on grain oil product to refine bioenergy, human basic existence is affected.At the problems referred to above, human passing through studied exploration, begins to utilize forest processing waste, stalk, animal excrement etc. as the material that refines bioenergy, as being made into biomass compact forming fuel with forest processing waste, crushed stalk after processing.At present, biomass compact forming fuel is used quite general abroad.China's biomass compact forming fuel producing technology and products thereof is also applied.By literature search, the patent (patent No.: 200710013240.5) disclose a kind of cotton stalk biomass granular fuel and production method that lucky height is declared during the Shandong Province.This cotton stalk biomass granular fuel is formed through mechanical workout by cotton bavin powder, cotton tankage slag and sawdust.Production method comprises: the cotton bavin section of cutting, pulverize batching, material loading, slaking, steps such as moulding.The cotton stalk biomass granular fuel thermo-efficiency height that utilizes this method to produce, easy to operate, igniting is easy, and reinforced number of times is few, and only need feed in raw material 1-2 time every day, and coal furnace need feed in raw material 6-7 time; Blowdown is low, and coal stove will discharge a large amount of sulfurous gas and flue dust in combustion processes, also will produce a large amount of lime-ash, and the not flammable component content of this biomass fuel is very low, after stove and accessory fully burns, has only a small amount of plant ash to discharge.Plant ash can be used as the fertilizer direct returning to farmland again, can not work the mischief to environment.The Wang Yong of the Jilin Province wealth patent (patent No.: 200810228817.9) disclose a kind of biomass granular fuel of forest tree castoff of declaring for another example, major advantage is to make forest tree castoff to be refined into the fiberous material of 8-13mm, the xylon of pulverizing below the 8mm of back is elected, oven dry, forest tree castoff and agricultural crop straw are through chipping, pulverize, screen, dispatching from the factory after the oven dry, granulation, cooling, pack.
Summary of the invention the present invention is according to above-mentioned situation;, stalk big and the fruitful characteristics of corn cob in conjunction with northern maize sown area; provide a kind of biomass compact forming fuel with maize straw and corn cob through processing, both saved Nonrenewable energy resources, protected environment again.This biomass compact forming fuel heating value when burning reaches the 3500-4500 kilocalorie, can substitute the use that coal satisfies the actual production life fully.Simultaneously, the byproducts such as lime-ash that the burning back produces can be done fertilizer and material of construction, so this biomass compact forming fuel has favorable economic benefit, social benefit and environmental benefit.
Technical scheme of the present invention is earlier maize straw and corn cob to be carried out the raw material seasoning, respectively maize straw and corn cob meal are broken into the following particle of 4m m then, carry out again that raw material is mixed, granulation, naturally cooling, screening, packing process, make biomass compact forming fuel.
The composition weight proportion of biomass compact forming fuel provided by the invention is:
Stalk: corn cob=90: 10; 80: 20; 70: 30; 60: 40; 50: 50.
The composition weight optimum ratio of biomass compact forming fuel provided by the invention is:
Stalk: corn cob=70: 30.
The technological method for processing that the present invention takes is: at first maize straw and corn cob are carried out seasoning; make moisture less than 15%; by whole set of processing equipment crushed corn straws and corn cob are transported to by proportioning afterwards and carry out high pressure in the nodulizer and granulate, can obtain finished product through naturally cooling, screening and packing after finishing.
Biomass compact forming fuel provided by the invention, energy-conserving and environment-protective, the thermal value height not only can fully replace Nonrenewable energy resources, and can reduce discharge of harmful gases such as carbonic acid gas, sulfurous gas.Simultaneously biomass compact forming fuel can solve fundamentally that stalk is stacked in the rural area and the corn cob floor space is big, influences landscape environment, unsafe factors such as initiation fire.
The mode of implementing by weight optimum ratio take by weighing through seasoning, moisture less than 15%, be ground into 6000 kilograms of 14000 kilograms of the following particulate maize straws of 4mm and corn cobs, send into stalk processing units ring mold forming machine then and granulate.Under the drive of ring mold forming machine, the pressing mold rotation, the frictional force that positive pressure produced by the binder hand-hole drives the pressure roller rotation, send into 2 pressure rollers equably and encircle the blanketed zone that mould is formed by 2 deflection scrapers on the feeder header board again, by ring mould and pressure roller 2 relative revolving parts material is pushed gradually and to clamp-on the ring nib, compact formed in nib, and constantly extrude outward, at last molding materials is discharged outside the machine.Add encircle the mold forming machine man-hour pressure-controlling at 50-100mpa, temperature is controlled at 100-120 ℃.Made product diameter 8mm, length 15mm, the finished product accepted product percentage is more than 95%.The packing of at last salable product being weighed is packaged as woven bag, every bag heavy 50kg.
