Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described reality
Applying example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
Logical technical staff all other embodiment obtained without creative efforts belongs to what the present invention protected
Range.
A kind of biomass straw shaped fuel, is made of the raw material of following parts by weight: 80-100 parts of tangerine bar, activated sludge
10-14 parts, 2-3 parts of compound additive；
The activated sludge is made by the following method:
(1) sludge is crossed into 24 meshes to remove suspension and solid impurity, the activated sludge solid content after sieve is adjusted to
2.5%, obtain pretreated sludge；
(2) the pretreated sludge of 100mL is taken to be placed in tetrafluoroethene beaker, it is 2% that 3-4mL mass fraction, which is inwardly added,
Ferric chloride solution after, first 200r/min quickly stirs 1min, then 60r/min mixes slowly 2min, cover cup lid be placed on it is micro-
In wave furnace, (power density 7W/mL, radiated time 100s) takes out and is cooled to room temperature after microwave radiation；
(3) moisture content of the sludge after microwave treatment is reduced to 5% hereinafter, obtaining activity by belt-type drying technique again
Sludge；
Microwave radiation can enhance the flocculation of activated sludge, and under microwave radiation, active pollution index is by microwave
Rupture occurs under the action of hot and non-thermal and releases a large amount of dissolubility biopolymer, the iron chloride being added at this time produces in water
Raw a large amount of Fe3+, these positively charged ions and the binding sites of dissolubility biopolymer exposure interact to be formed more
It for closely knit wadding body, can be also released between wadding body with combination water intracellular in the process, therefore reach good dehydration property
Energy；In addition, small part forms iron hydroxide after iron chloride is dissolved in water, the work that skeleton builds body is played during activated sludge dehydration
With, play enhancing dewatering performance of sludge effect；Activated sludge after dehydration, desiccation can change after mixing shaped fuel
It is apt to its flammability；The ignition temperature of shaped fuel and the type of its contained volatile matter are closely related, the volatilization in activated sludge
Divide based on fats, protein and carbohydrate, largely can be precipitated and burn in lower temperature, and the CaO energy in activated sludge
Enough be changed into hardly possible decomposition volatile matter easily decomposes volatile matter, so as to improve the flammability of shaped fuel, after tested, molding combustion
The ignition temperature of material is 283-298 DEG C；
The compound additive includes Ca (OH)2、SiO2、Al2O3, Ca (OH)2、SiO2、Al2O3Mass ratio be 10:2-
3:0.5-1；
Ca(OH)2It is decomposed into CaO, meeting and SO at high temperature2Reaction generates metastable CaSO4, reduction can be reached
SO2The effect of discharge, also, SiO2In combustion with CaSO4Effect generates the Ca of stability height and compact structure5
(SiO4)2(SO4) or 2C2S·CaSO4, to reduce SO2Release；In terms of denitration, K content is higher in stalk, under high temperature
The higher easy formation eutectic of Si, Ca, K content, on the one hand inhibits coke to burn, promotes NOxIn coke surface heterogeneous reduction,
Another aspect eutectic has to be complexed compared with the structure containing N in strong cohesive property, with stalk, reduces NOxRelease, in addition,
Al2O3With certain catalytic combustion-supporting effect, NO can also be inhibitedxRelease；Therefore, it is cooperateed between compound additive each component
Effect, can reduce SO in biomass molding fuel2And NOxRelease；
A kind of preparation method of biomass straw shaped fuel, includes the following steps:
The first step, the pretreatment of tangerine bar: adding water into stalk, and adjusting its moisture content is 50%, under 1.0MPa pressure
Steam blasting is carried out, the dwell time is 5min, after the completion of processing, is quickly taken out material, dries, crushes naturally；
Cellulose molecular chain after steam pre-treatment is broken, intramolecular hydrogen bond by a degree of destruction,
The mobility of cellulose chain increases, and is conducive to cellulose and changes to disordered structure, therefore, shaped fuel after steam pre-treatment
Intensity is 1.8-2.5 times higher than before handling, and combustion heat value is also obviously improved；Meanwhile the structure of cellulose changes after pretreatment,
Fiber size attenuates, becomes smaller, lignin increased activity, and penetrates between cellulose and form new connection, and internal cohesion is aobvious
Enhancing is write, lignin degradation meets again and moves to cellulose surface, softens to form solid bridge joint, Neng Gouti in compression forming
High-mouldability energy；
Second step will crush in pulverizer by pretreated stalk, cross 80 meshes and obtain stalk powder, by tangerine bar powder
End is put into air dry oven, and dry 72-80h makes its constant weight at 105 DEG C；
Third step, the tangerine bar powder by after drying, activated sludge and compound additive mixing, will be a certain amount of with spraying apparatus
Water be uniformly sprayed in raw material and be stirred for uniformly, obtain moisture content be 8%-11% raw material；
Moisture in raw material primarily serves the effect of bonding and lubrication in forming process, helps to reduce intergranular rub
It wipes, promotes particle be combineding with each other under pressure；When moisture content is too low, intergranular frictional force is larger, leads to particle
Sufficiently it cannot extend and flow, so that particle can not combine closely；On the contrary, particle can preferably expand when moisture content is excessively high
It opens up and flows, between extra moisture is extruded under the action of briquetting pressure and intersperses among particle in raw material, cause particle cannot
It tightly engages；Through density and durability test, when moisture content of the raw material is 8%-11%, shaped fuel has preferable molding effect,
The shaped fuel processed within this range is convenient for the transport and storage in later period；
4th step carries out processing and forming using biomass solid fuel compression-molding apparatus, specifically, keeping sleeve 34 downward
Movement is until contacting support chassis 11 and being fastened in annular groove 12, the raw material that third step is obtained is put into sleeve 34, is passed through
Heating coil heats the material in sleeve 34, and (128-133 DEG C, temperature sensor detection) stops after being heated to the temperature of setting
It only heats, with upright jack to the raw material uniform load in sleeve 34, control briquetting pressure is 90Mpa, keeps 3min recession
Jack (to prevent material rebounds while guaranteeing the well-bonded of internal particle) is gone, is removed after jack to being formed in sleeve 34
Fuel presses, and adjust sleeve 34 and be slowly move upwardly until and completely disengage shaped fuel, obtained shaped fuel stays in ring
In shape slot 12, biomass molding fuel is made；
It please refers to shown in Fig. 1-4, biomass solid fuel compression-molding apparatus, as shown in Figure 1, including pedestal 1, gear
Structure 2 and sleeve mechanism 3, wherein linkage mechanism 2 is installed on pedestal 1, and sleeve mechanism 3 is installed on linkage mechanism 2,1 He of pedestal
