Embodiment
Below in conjunction with Fig. 1 to agricultural wastes fuel-device of the present invention, be described further:
Agricultural wastes fuel-device of the present invention is made up of drying tower 1, pulverizer 2, modified tank 3 and single-lead-screw extruding briquetting machine 4.Have opening for feed 20 at drying tower 1 top, its internal side wall is provided with many group material traverse baffles 18, and the outlet at bottom 22 of drying tower 1 is promoted to the entrance 16 of pulverizer 2 by material conveyor belt 5.
Pulverizer 2 outlet at bottom 23 faces the entrance of sieve apparatus 6, the sieving plate 27 of the sidewall constant tilt of sieve apparatus 6, the bottom of sieving plate 27 is provided with outlet 24 facing to modified tank 3 top entry 25, the sidewall of sieving plate 27 top, sieve apparatus 6 has feed back mouth 19, feed back mouth 19 place is against the low side of sieving plate 27, and feed back mouth 19 is connected to the entrance 16 of pulverizer 2 through screw lift(elevator) 8.
Auxiliary material entrance 13 is arranged at modified tank 3 top, tank internal upper part is fixed with liquid material shower 10, and liquid material shower 10 is communicated with the steam unit outside tank, and in modified tank 3, bottom is provided with stirring arm 9, and the motor output shaft lower end that tank top is fixed secures stirring arm 9.Outlet at bottom 26 connection of modified tank 3 enters single-lead-screw extruding briquetting machine 4.
Single-lead-screw extruding briquetting machine 4 has upper feeding mouth, inside is provided with spiral propeller 11, tail end is provided with molding die 14, is provided with scraper 15 outside molding die 14.One end of spiral propeller 11 is connected with the motor 12 of single-lead-screw extruding briquetting machine 4 outer end, the other end is provided with extruding disk 28.
Said apparatus as required, can also be provided with hot-wind inlet 21 in drying tower 1 bottom, and connects hotblast stove 17 by blower fan 7.
The method of agricultural wastes fuel-device fuel of the present invention, its concrete workflow is that-drying-pulverizing-modified-extrusion molding-deep processing is selected in agricultural wastes classification.
Agricultural wastes have a variety of, what manufacture agricultural wastes fuel requirements is organic composition in agricultural wastes, comprise straw, weeds, chaff skin, wooden slag bits, tree root branches and leaves, animal manure etc., after artificial or machine are selected, the raw material obtaining organic composition is carried out natural air drying airing or put in drying tower 1 carrying out drying, moisturely after raw material drying is divided into 12% ~ 15% of total mass.By drying tower 1 airing, that the warm air in hotblast stove 17 can be incorporated in drying tower 1 by blower fan 7 by hot-wind inlet 21 below drying tower 1, owing to being provided with many group herringbone material traverse baffles 18 in drying tower 1, raw material can be disperseed under the effect of material traverse baffle 18, and fully contacts with warm air in the process of dispersion.
Dry raw material then drops on raw material travelling belt 5 by the outlet at bottom 22 of drying tower 1, via the lifting transmission of raw material travelling belt 5, raw material enters pulverizer 2, pulverizer 2 is by raw material pulverizing and be sent in sieve apparatus 6 by pulverizer 2 outlet at bottom 23, sieve apparatus 6, through screening, makes granular size meet 5 ~ 80 object feed particles and enters modified tank 3.Undesirable raw material then loops back pulverizer 2 entrance 16 via with sieve apparatus 6 feed back mouth 19 through screw lift(elevator), again pulverizes or abandons.
In modified tank 3, the parts by weight of component are: raw material 50 ~ 80 parts, clay 10 ~ 20 parts, coal dust 5 ~ 10 parts; Described raw material comprises straw 10 ~ 50 parts, 0 ~ 30 part, weeds, chaff skin 0 ~ 30 part, 0 ~ 30 part, wooden slag bits, 0 ~ 30 part, tree root branches and leaves, animal manure 0 ~ 30 part.
Modified tank 3 adds solid adjuvant material from auxiliary material entrance 13, and from liquid material shower 10 spraying liquid auxiliary material, keep mixture temperature to be 200 DEG C ~ 500 DEG C, the water content of mixture is 15% ~ 25% of total mass.Uniformly mix with stirring rake 9 in the process.Auxiliary material comprises fog, coal dust, clay etc., coal dust inserts in raw material as ignition dope and the last fuel generated can be allowed inflammable, clay can increase the viscosity of feed particles as tackiness agent, feed particles is allowed to be more prone to shaping, fog is used for the humidity of modified raw material and temperature, raw material is reached be suitable for extruding the condition of granulating, allow material extruding is more smooth and easy avoids vexed machine.
Raw material is modified through fog, and high-temperature mist can soften the xylogen in feed particles, and xylogen is melted, and improves the tackiness between feed particles, is convenient to feed particles extruding to be combined into new shape.
Mixing raw material is sent between extruding disk 28 and molding die 14 by the spiral propeller 11 in single-lead-screw extruding briquetting machine 4, and extruding disk provides pressure to extrude mixing raw material, and the pressure of extruding mixing raw material is 50MPa ~ 130MPa.The xylogen contained in mixing raw material softens at a certain temperature and cohesive force increases, and being on the increase along with mixing raw material, in the process of extruding, pressure and frictional force increase gradually.Under the effect of extruding disk, make mixing raw material fiber molecule roll into a ball dislocation, distortion, extending and under the effect of clay, reconfigure the shaping fuel become without excision forming extrudes away from molding die 14, and the scraper 15 be provided with in molding die 14 outside can cut according to the length of required fuel pellet.
Shaping fuel, after super-dry, is placed in carbonizing apparatus and smoulders under the condition of anoxic, or destructive distillation in the absence of oxygen, can obtain machine-processed carbon.Its combustion gas generated in carbonization process, tar etc. can be recycled.Agricultural wastes fuel-device except as preparing except fuel, can also be used to manufacture fertilizer, feed and providing basic material for Chemical Manufacture, more can be squeezed into the use such as sheet material, disposable environmental protection tableware under the help of specific equipment.
