Embodiment 1
[0029] This embodiment provides a derived fuel based on organic waste fermentation residue, its composition and weight percentage ratio is: organic waste fermentation residue 75%, anthracite 15%, wood chips 5%, calcium oxide 3%, binder 2% ; Among them, the binder is prepared by 0.3% sodium carboxymethyl cellulose, 0.7% limestone, and 1% bentonite.
[0030] The preparation method of above-mentioned derivative fuel comprises the steps:
[0031] S1. After adding 1% lactic acid fermenting bacteria and 0.5% glucoamylase to the food waste, ferment at 30°C for 10 days, then separate the fermentation product lactic acid, and bake the remaining residue at 105°C to constant weight.
[0032] S2. Crush the anthracite to a particle size of 2-8mm, and the sawdust to 10-15mm; then mix the organic waste fermentation residue obtained in S1, anthracite, wood chips, and calcium oxide powder according to the above ratio, stir evenly, and let stand for 30 minutes ; Add the binder according to the...
Embodiment 2
[0036] This embodiment provides a derived fuel based on organic waste fermentation residue, its composition and weight percentage ratio is: organic waste fermentation residue 50%, anthracite 25%, wood chips 20%, calcium oxide 2%, binder 3% ; Among them, the binder is prepared by 0.8% sodium carboxymethyl cellulose, 1% limestone, and 1.2% bentonite.
[0037] The preparation method of the above-mentioned derived fuel is basically the same as in Example 1, except that the organic waste in S1 is discarded vegetable leaves and fruits in the farmer's market, and it is anaerobically fermented at 40°C for 20 days, and the fermentation residue is collected at 200 °C to constant weight; the standing time in S2 is 15 minutes; the drying temperature in S3 is 200 °C.
[0038] The calorific value of the derived fuel based on the fermentation residue of organic waste prepared by the above method is 27868.7kJ / kg.
Embodiment 3
[0040] This embodiment provides a derived fuel based on organic waste fermentation residue, its composition and weight percentage ratio is: organic waste fermentation residue 85%, anthracite 5%, wood chips 5%, calcium oxide 2%, binder 3% ; Among them, the binder is prepared by 0.2% sodium carboxymethyl cellulose, 0.5% limestone, and 2.3% bentonite.
[0041] The preparation method of the above-mentioned derived fuel is basically the same as in Example 1, the difference is that in S1, the straw of agricultural and forestry waste is used to ferment ethanol at 30°C for 7 days after adding cellulolytic bacteria and cellulase, and after distilling to obtain ethanol , bake the remaining residue at 300°C to constant weight; the standing time in S2 is 45 minutes; the drying temperature in S3 is 200°C. The calorific value of the derived fuel based on the fermentation residue of organic waste prepared by the above method is 25769.5 kJ / kg.
