Second step, the preparation of basic fuel layer, first pulverize the agricultural wastes as biomass material, natural air drying or After drying, add the secondary stock of certain proportioning and/or hydrolysis fiber as fiber-like binding agent, stir, add and necessarily contain The quick lime of amount is stirred uniformly, being then placed in forming press extruded again, extruded obtained basic fuel Layer is cuboid square block, the size being smaller in size than described solid fuel layer of basic fuel layer；
3rd step, the preparation of sealing fuel bed, first carried out lignin and/or the oil crop garbage as biomass material Pulverize, after natural air drying or drying, add the thermosetting resin of certain proportioning, stir, put into and forming press adds hot extrusion Molding, the extruded obtained fuel bed that seals is rectangular sheet shape, seals the length of fuel bed more than basic fuel layer Length and basic fuel layer, the thickness sum of solid fuel layer, seal the width of fuel bed more than basic fuel layer width with Basic fuel layer, the thickness sum of solid fuel layer；
4th step, preliminary pressing and forming, carry out rough surface process by the upper and lower surface of basic fuel layer, and at basic fuel The upper and lower surface of layer coats solubility thermosetting resin, basic fuel layer is sandwiched two-layer between two parties and seals between fuel bed, solid Fluid fuel layer sandwiches between basic fuel layer and solid fuel layer, and the edge sealing fuel bed covers solid fuel layer completely, puts Entering twin rollers heating to roller, making solid fuel layer be fixed by pressing becomes seal between fuel bed and basic fuel layer sandwich Layer, obtains the sandwich of layers biomass molding fuel of preliminary pressing and forming；
5th step, edge sealing second pressing molding, respectively at the sandwich of layers biomass molding fuel of preliminary pressing and forming of gained Solubility thermosetting resin is coated on four limits, and four limits to sandwich of layers biomass molding fuel carry out inclination and put into twin rollers respectively In, thermoplastic, with basic fuel layer and seal fuel bed joint portion as fulcrum, slowly bend, bent respectively by one side, Make the sealing fuel bed contact close to each other at protrusion basic fuel layer upper and lower surface edge, finally make the edge of sealing fuel bed in V-shape mutual pressing edge sealing, is completely enclosed within basic fuel layer and seals in the inner space that fuel bed is formed, can be prepared into To final high fuel value biomass molding fuel.
Further, described sealing fuel bed includes lignin, oil crop garbage and solubility thermosetting resin.Wood Quality and its quality of oil crop garbage are dense, by adding solubility thermosetting resin after pulverizing, extrude adhesion, anti- Water effect is more excellent.
Further, described basic fuel layer includes agricultural wastes and fiber-like binding agent.Agricultural wastes source is wide General, with low cost, fiber-like binding agent is the feature of fiber substance for agricultural wastes, had both met pressing requirement, and had saved again Cost-saving.
Further, one during described agricultural wastes include straw, corn cob, bagasse, algae and Herba Eichhorniae or More than one mixture, wide material sources, with low cost.
Further, described lignin includes one or more the mixture in wooden unit, wood flour and bark, described Oil crop garbage includes one or more the mixture in Semen Gossypii, fiber crops seed and Aleurites fordii Hemsl..Lignin and oil crop Garbage quality is fine and close, and inherently biomass material, by good water-proof effect extruded under the effect of binding agent.
Further, described fiber-like binding agent is secondary stock and/hydrolysis fiber, and wide material sources are with low cost.
Further, the thickness of described solid fuel layer and described basic fuel layer is than for 1:30～1:70.
Further, described basic fuel layer is Puffer-type basic fuel layer, and described Puffer-type basic fuel layer is in preparation During add and be equivalent to biomass crumb feedstock siccative weight 3～the Kaolin of the quick lime of 8%, 2～5%, inflation mixing is all Even.
Further, the number of plies of described basic fuel layer be two-layer and more than.
Further, it is provided with solid fuel layer between described basic fuel layer.

In the present embodiment, described sealing fuel bed includes lignin, oil crop garbage and solubility thermosetting tree Fat.Described basic fuel layer includes agricultural wastes and fiber-like binding agent.Described agricultural wastes are Herba Eichhorniae.Described wooden Element includes that the mixture in wooden unit and bark, described oil crop garbage include Semen Gossypii mixture.Described fiber-like binding agent For secondary stock and hydrolysis fiber.The thickness of described solid fuel layer and described basic fuel layer is than for 1:60.Described basic fuel The number of plies of layer is six layers.It is provided with solid fuel layer between described basic fuel layer.
Comparative example 1
The preparation method of a kind of high fuel value biomass molding fuel, its concrete structure is same as in Example 1, is uniquely distinguished as Not having solid fuel layer between basic fuel layer and sealing fuel bed, the thickness of solid fuel layer is by basic fuel layer generation Replace.
Comparative example 2
The preparation method of a kind of high fuel value biomass molding fuel, its concrete structure is same as in Example 3, is uniquely distinguished as Not having solid fuel layer between basic fuel layer, the thickness of solid fuel layer is replaced by basic fuel layer.
Meanwhile, in order to assess the concrete technique effect of the biomass molding fuel of high fuel value of the present invention, respectively from The concrete combustibility of embodiment 1～6 is tested by the aspects such as calorific value, combustion rate and heating rate.Concrete test data such as table 1 institute Show:
Table 1 different embodiment concrete combustibility test data
Group number Embodiment 1 Embodiment 2 Embodiment 3 Embodiment 4 Embodiment 5 Embodiment 6 Comparative example 1 Comparative example 2
Calorific value (kcal/kg) 5630 5520 5780 5880 5838 5580 5120 5250
Combustion rate (%) 96.7 95.8 96.2 97.4 98.9 96.9 93.2 92.8
The thermal efficiency (%) 96.4 95.7 96.1 95.4 97.3 96.3 91.3 91.6
As can be seen from Table 1, the present invention prepares the biomass molding fuel calorific value of gained in more than 5500lcal/Kg, combustion rate More than 95%, the thermal efficiency is more than 95%.And the concrete combustibility of traditional biomass molding fuel is: calorific value 4500～ 4800kcal/kg, combustion rate is between 90～96%, and heating rate is between 80～90%.By contrast, the high fuel value of the present invention is raw Material shaped fuel is all obviously improved, before having a wide range of applications in combustibility indexs such as calorific value, combustion rate and heating rates Scape.Meanwhile, the calorific value of comparative example is at about 5200kcal/kg, and combustion rate is about 93%, and heating rate, about 91%, passes through Solid fuel layer is set, the combustibility of biomass extrusion materials can be obviously improved.And, from table 1 data it will be seen that reality Executing example 5 to contrast with embodiment 6, using Puffer-type biomass molding fuel is to improve biomass extrusion materials combustibility to have one Fixed effect,
The above, only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction；All one's own professions The those of ordinary skill of industry all can shown in by specification and the above and implement the present invention swimmingly；But it is, all that to be familiar with basis special The technical staff of industry in the range of without departing from technical solution of the present invention, available disclosed above technology contents and make a little Permitted the equivalent variations changed, modify and develop, be the Equivalent embodiments of the present invention；Meanwhile, all essence skills according to the present invention The change of any equivalent variations that above example is made by art, modify and differentiation etc., all still fall within technical scheme Protection domain within.
