Description
Technical field
The present invention relates to a kind of method that thereby organic waste is prepared agriculture charcoal through pyrolysis way carbonization, activation.
The invention still further relates to a kind of device that is used to realize aforesaid method.
Background technology
2007 the world " agriculture charcoal " initiate conference and hold at New South Wales, Australia, various countries scientist and business circles have caused " agriculture charcoal " technical study and utilization shows great attention to.
" agriculture charcoal " is with organic raw material such as animal excrement, rice husk, Pericarppium arachidis hypogaeae, cornstalk, trees waste materials (Agrichar); The same residue of similar charcoal that under oxygen-free environment, forms behind the low temperature pyrogenation, the carbon in about 50% the organic raw material is retained in wherein.
The newest research results of Australia 5 rumba Agricultural Research Institute has been reconfirmed the great potential of " agriculture charcoal " technology.The researchist tests by the amount that the per hectare farmland applies 10 tons " agriculture charcoals ", and the result shows that " agriculture charcoal " can make the output of wheat increase by 3 times, makes the output of soybean increase more than 2 times.Simultaneously, they also use nitrogenous fertilizer and " agriculture charcoal " and nitrogenous fertilizer separately and are used for comparing test, find that output is basic identical.This explanation uses " agriculture charcoal " just can play the effect of increasing production the same with using nitrogenous fertilizer separately.
" agriculture charcoal " technology can also significantly reduce the discharging of greenhouse gases.The famous scientist's Tim Fu Lannarui of Australia points out that in the world, the greenhouse gases amount that soil discharges is more than 10 times of greenhouse gases that fossil-fueled produces.Through the gas that discharges in the soil is measured and contrasted, find that " agriculture charcoal " can significantly reduce the release of carbonic acid gas and nitrous oxide.And nitrous oxide is another kind of more serious greenhouse gases, and its effectiveness of making Greenhouse effect is 300 times of carbonic acid gas, and is sustainable 150 years in air.
The Australia 5 another one environmentalist Steve Ken Mubai of rumba Agricultural Research Institute point out that " agriculture charcoal " also brings another benefit for peasant and environment.Carbon in the forms such as farm crop remnants, mulching material and mixed fertilizer is unsettled in soil, in two to three years, will thoroughly decompose, and changes into carbonic acid gas.And " agriculture charcoal " is very stable in soil, and carbon wherein can keep the time of centuries.This means that use " agriculture charcoal " and the mixed fertilizer of equivalent, " agriculture charcoal " once just can push up decades, and mixed fertilizer will use every year, this can reduce peasant's expenditure undoubtedly.For environment, because unsettled, labile carbon is replaced by stable " agriculture charcoal ", the amount of carbon dioxide that soil discharges will significantly reduce.

(11) the mixing gas of water vapor and the gas formation that contains combustiblecomponents through vapor pipe 64, swivel joint 68, mixture pipe 70, gets in the mixed steam purification apparatus under the effect of discharge fan in the heating drum 62.The mixed steam purification apparatus is known products-spray column.Moisture in the mixed steam purification apparatus in the mixed steam becomes water of condensation after handling through spray, discharges through the water port 74 of mixed steam purification apparatus.Inflammable gas such as methane, ethane is transported to the methane gas burner 19 of steam boiler 20 in the mixed steam through combustible gas outlet 71, discharge fan 75, the combustible gas pipeline 98 of mixed steam evolution treatment facility.
(12) because the methane gas that produces in the thermal decomposition of organic wastes process is unstable; Therefore steam boiler need keep that burning things which may cause a fire disaster is arranged in the burner hearth all the time with natural gas burner; Be the methane gas igniting; Guarantee methane gas can be safely in the steam boiler burner hearth, burning reliably, avoid cutoff, detonation etc.When the inflammable gas shortage of heat that produces, replenish by natural gas burner, enough steam and flue gas are arranged when guaranteeing activation.
(13) when the temperature of heating chamber 61 reaches 650～750 ℃, steam flue gas T-valve is rotated to steam flue gas mixed gas outlet 43 be communicated with the material conveying pipe of swivel joint 44 1 sides; Valve on the chimney 97 50 is turned down, opened the steam valve 5 of heat-accumulator tank 7.Steam gets into steam flue gas mixing equipment 32 through steam-pipe 101, vapor pressure equilibrium valve 99, steam-flow meter 100, steam-in 31.The quantity of input steam and the ratio of the carbon in the heating drum 62 are 500～700m
3: 1t.Under the suction function that when vapour stream is crossed venturi tube, produces, flue gas gets into steam flue gas mixing equipment 32 from gas approach 30.Steam flue gas mixing equipment 32 steam-ins 31 are 1: 2 with the bore ratio of gas approach 30.Steam and flue gas mix the back and get in the heating drum from steam flue gas mixed gas outlet 43, swivel joint 44, interior transport pipe 45 in venturi tube, the carbon that thermal decomposition of organic wastes is generated carries out activation, increases the hole of carbon.The input of steam flue gas gas mixture was at first closed the power supply of power inverter 81 after 15～30 minutes.Steam off valve 5 when the temperature in the heating chamber 61 is reduced to 600～700 ℃.
(14) when the temperature in the heating chamber 61 drops to 200～300 ℃; At first stopping heating drum 62 rotates; Change heating drum 62 turning directions then, heating drum 62 is seen from gas mixture purification apparatus 72 1 ends, turn round with 5r/min speed counter clockwise.Carbon is pulled to the rear end of heating drum 62 in the heating drum 62 under the effect of turning over charging guide plate 63, gets into marker board 84; Under the effect of marker board 84, carbon gets into discharging cylinder 47; Under the effect of the spiral charging guide plate 41 in discharging cylinder 47, get into discharge chamber 46, be deposited in the bottom of discharge chamber 46; Below the drain hole 39 of discharge chamber 46 forwards at every turn; The drain hole 39 of discharge chamber 46 is down the time, and lid 38 is because the effect of gravity is opened downwards, and the carbon of discharge chamber 46 bottoms is emitted from drain hole 39; Get into out in the feed bin 37, the discharge port below going out feed bin 37 36 is discharged again.
(15) when heating drum 62 operation or discharging, have a spot of dust and get into out in the feed bin 37 from the drain hole 39 of heating drum 62, discharging cylinder 47, discharge chamber 46, be leaked to discharge room 51 from discharging cylinder 47 and the seals at that goes out between the feed bin 37 again.The dust that is leaked in the discharge room 51 will get into fly-ash separator 2 through dedusting mouth 53, dedust air duct 58, cleaning shaft 3.Being leaked to the slag-drip opening 87 of dust heavier in the discharge room 51 below discharge room 51 falls in the dreg discharging box 35 in the deslagging chamber 96.
(16) in operational process,, start fan 96 and dispel the heat if between electricinstallation 83 or the temperature of solenoid 82 when high.
