Technical field
The present invention relates to biomass industrial produced wastes environmental protection comprehensive utilization field, especially utilize biomass industrial produced wastes to produce the method for granular fuel.
Background technology
At present, because the minimizing of Nonrenewable energy resources in the world wide, the China even the whole world are also more and more paid attention to the comprehensive utilization of reproducible biomass energy.Utilize biomass industrial production enterprises such as straw, timber tankage, as: furfural/furfuryl alcohol factory, wood sugar/Xylitol factory, pulp manufacturer, glucose and Alcohol Production factory etc. all are to have utilized the Mierocrystalline cellulose in the plant, hemicellulose in process of production, and other compositions such as xylogen in the plant are promptly discharged as trade waste.Because moisture content has nothing in common with each other in the feasible trade waste of discharging of the difference of each factory's product and production technique, moisture is lower than 50% the special-purpose slag boiler that burns of trade waste utilization, and the production steam that can burn is for producing use; And moisture is higher than 50% trade waste and is difficult to directly burn in boiler; And can carry out the incendiary trade waste also since little, the light weight of tap density under the effect of boiler induced-draft fan, can't fully burn at burner hearth bottom, cause in burner hearth, cannot keep under control fire, burning is insufficient.
The fuel major part of uses such as home-use heating fireplace and chafing dish, barbecue is a charcoal, and the making of charcoal need be used a large amount of timber and can pollute atmosphere in firing the charcoal process.
Granular fuels such as the root of general plant, stem, leaf must evenly stir adding salt, ignition dope, tackiness agent after the raw material pulverizing, and then mixed raw materials is carried out granulation.As the Chinese patent (patent No.: CN0113674115).Can raise the cost and add ignition dope, additive etc.So this prilling process does not fit into the granulation of biomass industrial produced wastes.
Summary of the invention
The objective of the invention is to overcome above defective, a kind of method of utilizing biomass industrial produced wastes to produce granular fuel is provided, make the waste that produces in all biomass Industrial processes no matter moisture what can both be by acting as a fuel burning after the granulation, thereby biomass are produced waste ' s reclamation, turn waste into wealth; And produce granular fuel production process technology complexity before overcoming, need to add additives such as tackiness agent, ignition dope and could produce qualified granular fuel, overcome technical requirements height in the production process, shortcoming that product cost is high.
Technical scheme of the present invention is: a kind of method of utilizing biomass industrial produced wastes to produce granular fuel; it is characterized in that; with moisture 30～35% biomass industrial produced wastes; utilize heat that waste produces in the process of ring mode nodulizer extrusion molding with material in contained humidity vaporize to soften material; after the granulation, through the cooling, sieve finished product.
Above-mentioned moisture 30～35% biomass industrial produced wastes are got through pulsed pneumatic drier drying by the biomass industrial produced wastes that is higher than 35%.
Above-mentioned moisture 30～35% biomass industrial produced wastes, dry and be lower than 30% biomass industrial produced wastes and mix and get by being higher than 35% biomass industrial produced wastes through pneumatic drier.Time of drying was at 0.5～5 second.

For clarity sake, below technical scheme of the present invention is further specified.
With the size of biomass industrial produced wastes (waste residue) according to original moisture, with 30～35% is boundary, being higher than 30～35% waste (waste residue) enters pneumatic drier and carries out drying, be dried to after the certain humidity with after the waste that is lower than 30～35% moisture (waste residue) mixes and carry out pelletizing forming, do not add any additives, ignition dope etc. in the granulation process.Utilize heat that waste produces in the process of extrusion molding with material in contained humidity vaporize to soften material, under the effect of nodulizer pressure, make material be compressed into particle.The higher not easy-formation of particle temperature after the compressed moulding needs to cool off aftershaping after granulation finishes; and can produce a small amount of particle in the extruding pelletization must sieve the particle after granulating, and the particle that screening is come out returns in the nodulizer again granulates.Finished particle then is transported to boiler shop and sends into and burn in the boiler or pack the back and sell.
Do not need adding additives and auxiliary agent in material during this shaping particles equipment work, the bounding force during its moulding mainly is the xylogen behind hot mastication in the material.Material makes water generates steam in the material soften xylogen in the material because acting produces heat in extrusion process, and the xylogen after softening can get up the biomass waste particle bond after overstocked and finally finalize the design after cooling off.
The invention has the beneficial effects as follows, can make the waste that produces in all biomass Industrial processes no matter moisture what can both be by acting as a fuel burning after the granulation, thereby biomass are produced waste ' s reclamation, turn waste into wealth; And produce granular fuel production process technology complexity before overcoming, need to add additives such as tackiness agent, ignition dope and could produce qualified granular fuel, overcome technical requirements height in the production process, shortcoming that product cost is high.The present invention thoroughly solved biomass industrial produced wastes because of the moisture height causes different factories can't the incendiary problem and, the light weight little inadequate problem that causes burning because of tap density.The granular fuel of manufacturing of the present invention can replace charcoal as uses such as warming stove and chafing dish, barbecues, has not only saved that a large amount of timber prevent the pollution of the environment but also can be for biomass industrial production enterprise turns waste into wealth, comprehensive utilization of energy opens up a new way.
Description of drawings
Accompanying drawing is a process flow sheet of the present invention.
Embodiment
By technical process shown in the drawings, systems such as the drying of biomass trade waste, granulation, cooling, screening are installed couple together.With the furfural dregs is example,
Furfural dregs is packed into forklift and is fallen on the vibratory screening apparatus 2 with rotary conveyor on the hopper of rotary conveyor 1, wherein big particle and foreign material are sifted out the back pulverizing by vibratory screening apparatus 2 and return vibratory screening apparatus again, and the furfural dregs that granularity is qualified is admitted to break up with heated air and carries out drying in the pneumatic drier.In vapor heat exchanger 3, air and steam enter in the vapor heat exchanger 3, and water of condensation flows out from the bottom, and heated air is sent into and broken up in the pneumatic drier 4.
The caliber of breaing up pneumatic drier 4 alternately dwindles and enlarges, and has high heat and mass effect intensified drying process thereby give full play to accelerating sections; The material particle that adds at first enters in the little drying tube of caliber, and particle obtains quickening, when its accelerated motion at the end, dry caliber sudden enlargement, particle enters the big drying tube of caliber according to inertia.Particle is in moving process, constantly slow down owing to be subjected to resistance, drying tube dwindles suddenly again until slowing down at the end, this like-particles is accelerated again, so the repetition alternative dwindles caliber and enlarges, then also alternative acceleration and deceleration of the movement velocity of particle makes air and interparticle speed of relative movement and heat transfer area all bigger, thereby improved the intensity of heat and mass.Simultaneously, gas velocity descends the also corresponding time of drying that increased in the enlarged tube.Dried furfural dregs separates slag through two stage cyclone separator 6 with hot gas flow, hot gas flow is through first centrifugal fan 5 and emptying, dry qualified furfural dregs is sent in first small feed bin 8 with spiral screw feeder 7, and it is even with mixing of materials through putting into stirrer 10 after electronic scales 9 weighings to be got off by first small feed bin.The material that mixes through lift 11 deliver in second small feed bin 12 through speed governing screw feeder 13 uniformly feeding speed put into and encircle modeling pelletizer 14.Particle after the moulding needs cooling and shaping, screening to pulverize, process counterflow cooler 17 is with the particle cooling and shaping earlier, particle after the typing is delivered to outside the venue through rotary conveyor 19 material movers 20 through vibratory screening apparatus 18 screening back finished particles, screenings is got back to granulation again in the lift, collect to send into again after the dust that freezing air is taken away during cooling separates with cyclonic separator 16 and carry out granulation in the stirrer, gas is through centrifugal fan 15 emptyings.
Key problem in technology of the present invention is the drying and the molding particles of the high trade waste of water content.Why strobe pulse formula pneumatic drier is because the drying plant of this kind form has the advantages that dry tenacity is big, time of drying is short, thermo-efficiency is high, powder application particulate materials scope is wide in the present invention.The pulsed gas flow drying machine is follow-on pneumatic conveying dryer, is made up of the pipeline that alternately enlarges and dwindle, and is divided into accelerating sections and reduction of speed section.Hot gas flow through drying plant enters powder and the dust separated and collected of second cyclone dust extractor with entrainment of warm air.These tornado dust collector have downward-sloping tangent to helix type gas feed, and top board is the guide plate of spiral type.Because gas from tangentially entering, has the effect of guide plate again, can eliminate entering the little vortical flow that gas makes progress and flows and form, reduce kinetic energy consumption, improve efficiency of dust collection.
Molding particles equipment is to utilize feed or fertiliser granulates forming machine, at the characteristics of biomass industrial produced wastes its part transformation is formed.Because biomass waste is little than the tap density of feed or fertilizer, the output of therefore using this machine granulation is starkly lower than the output of feed or fertilizer.Therefore need this shaping particles equipment is transformed; it mainly is the structure of having improved running roller and ring mould; having strengthened the compacting width has increased the production capacity of nodulizer, thereby and has further accelerated the particulate quantum of output according to the reduction ratio that the power requirement of motor has suitably strengthened step-down gear the production capacity of nodulizer is increased.General biomass waste granulation output is about 1/5～1/3 of same type machine feed or fertilizer, the reduction ratio of step-down gear is increased to 2～4 times of original transformations of adding running roller and ring mould make power of motor just in time satisfy service requirements, and about 3～5 times of production capacity that can also the accretion material.
Concrete explained hereafter step is as follows:
1), at first with material moisture content greater than 35% be dried to moisture content less than 35%, drying mode adopts the pulsed gas flow drying.Specification: Φ 600～800 * 25000, the caliber of drying machine alternately dwindles and enlarges, and has high heat and mass effect intensified drying process thereby give full play to accelerating sections; The material particle that adds at first enters in the little drying tube of caliber, and particle obtains quickening, when its accelerated motion at the end, dry caliber sudden enlargement, particle enters the big drying tube of caliber according to inertia.Particle is in moving process, constantly slow down owing to be subjected to resistance, drying tube dwindles suddenly again until slowing down at the end, this like-particles is accelerated again, so the repetition alternative dwindles caliber and enlarges, then also alternative acceleration and deceleration of the movement velocity of particle makes air and interparticle speed of relative movement and heat transfer area all bigger, thereby improved the intensity of heat and mass.Simultaneously, gas velocity descends the also corresponding time of drying that increased in the enlarged tube.
Because dispersion and agitaion when dry are brought in constant renewal in the gasification surface, exsiccant conducts heat, mass transfer process intensity is bigger.The gas-solid biphase is extremely short duration of contact, and time of drying is generally at 0.5～2 second, and is the longest 5 seconds.
2), owing to be to be catalyzer and be hydrolyzed or boiling after the straw that crushes etc. mixes in most of biomass industrial production enterprise production process with acid, alkali, therefore the waste that produces need not be pulverized substantially and can directly granulate, if grain diameter must be pulverized with pulverizer after drying greater than 10mm.
3), pelletizing forming: adopt the ring mode nodulizer, this machine partly is made up of frame, belt drive system, adjustable running roller assembly etc.Do not add steam regulation of texture, conditioning of texture in the pelletization, do not add any additives, particulate component is even, and external form is neat, smooth surface, can conversion between Φ 1.5～10mm according to the different diameter of mould specification, compression ratio is 1: 2～1: 8, length can be regulated between 5～10mm.
4), particulate cooling, screening.After raw material was granulated, particle temperature very high (generally reaching 95～105 ℃) and contain a small amount of particle was so must cool off and screening makes the particle cooling and shaping and sifts out particle.Cooling screening plant 20～30min cooling time, particle is lowered the temperature greater than 50, and the particle rate is less than 3%, and screen rate is greater than 95%.The particle that the screening back produces returns in the pelletizing forming equipment again granulates.
5), finished particle be sent to boiler burn or pack the back sell as granular fuel.
