example 1

[0025] Dig and build a treatment pool with a length of 2m, a width of 1m, and a depth of 0.8m in a greenhouse with a temperature of 30°C and a relative air humidity of 60%. After mixing cow dung and river bottom sludge at a mass ratio of 3:1 Obtain the retting substrate, pour the retting substrate into the treatment tank, and let it stand for retting for 15 days; after the above retting is completed, add polyacrylamide with 1% cow dung mass to the treatment tank, and stir and mix for 20 minutes After standing and aging for 12 hours, the upper layer of liquid was extracted to obtain the lower layer of sediment, and the sediment, sodium peroxide and water were mixed according to the mass ratio of 10:1:5, and immediately poured into the mold, and then freeze-dried after standing for 20 minutes of foaming. The porous fuel body was obtained and set aside; the grapes falling from the vineyard were collected, rinsed with deionized water for 3 times, and then put into a tissue pulveriz...

[0027]Dig and build a treatment pond with a length of 2.5m, a width of 1.5m, and a depth of 1.2m in a greenhouse with a temperature of 35°C and a relative air humidity of 65%. Cow dung and river bottom silt are mixed at a mass ratio of 3:1. After mixing, the retting substrate is obtained, and the retting substrate is poured into the treatment tank, and left to stand for retting for 17 days; after the above retting is completed, add polyacrylamide with 1% cow dung mass to the treatment tank, stir After mixing for 25 minutes, let it stand and age for 13 hours. After extracting the upper liquid, get the lower sediment. Mix the sediment with sodium peroxide and water according to the mass ratio of 10:1:5, pour it into the mold immediately, let it foam for 25 minutes, and then freeze it. Dry to obtain a porous fuel body and set it aside; collect the grapes falling from the vineyard, wash them with deionized water for 4 times, and put them into a tissue pulverizer for 3 hours to obta...

[0029] Dig and build a treatment pool with a length of 3m, a width of 2m, and a depth of 1.5m in a greenhouse with a temperature of 40°C and a relative air humidity of 70%. After mixing cow dung and river bottom sludge at a mass ratio of 3:1 Obtain the retting substrate, pour the retting substrate into the treatment tank, and let it stand for retting for 20 days; after the above retting is completed, add polyacrylamide with 1% cow dung mass to the treatment tank, and stir and mix for 30 minutes After standing and aging for 14 hours, the upper layer of liquid was extracted to obtain the lower layer of sediment, and the sediment, sodium peroxide and water were mixed according to the mass ratio of 10:1:5, and immediately poured into the mold, and then freeze-dried after standing for 30 minutes of foaming. The porous fuel body was obtained and set aside; the grapes falling from the vineyard were collected, rinsed with deionized water for 5 times, and then put into a tissue pulveriz...

Abstract

The invention relates to the technical field of clean fuel preparation, in particular to a preparation method for low-ash high-combustion-value bio-fuel. According to the method, firstly, with cow dungs containing a large quantity of flammable crude fibers as raw materials, sufficient microorganisms contained in sludge are utilized to degrade the cow dungs, and meanwhile macromolecular organic matter in the cow dungs and the sludge is converted into micromolecular organic matter; grapes and yeast powder are utilized for fermentation to obtain a fermentation solution rich in pohytol, anhydrous sodium sulfate is utilized to absorb water in the fermentation solution, and the concentration of pohytol is increased; then, calcium oxide, sodium hydroxide and organic carboxylic acid in the fermentation solution are utilized for a decarboxylic reaction at high temperature, carbon dioxide is released through the decarboxylation of organic carboxylic acid, and organic carboxylic acid itself is converted into hydrocarbon substances with high combustion efficiency; a porous blank fuel body is soaked in a reaction solution with a high combustion value; in addition, the biomass fuel prepared by the porous blank body is large in surface area and can be fully in contact with oxygen during combustion and fully combust without generating poisonous gas and ash in use.

Description

technical field [0001] The invention relates to the technical field of clean fuel preparation, in particular to a method for preparing biofuel with low ash content and high combustion value. Background technique [0002] The petroleum, coal, and natural gas fossil energy commonly used by humans are non-renewable, have limited global reserves, and emit large amounts of greenhouse gases and pollutants. With the over-exploitation and utilization of global oil resources, petrochemical resources are facing the danger of depletion, and the greenhouse gases such as carbon dioxide and other waste gas pollution emitted during the use of petrochemical fuels have also become a huge challenge for mankind, seriously destroying the ecological balance. A series of problems such as the depletion of petrochemical energy and the deterioration of the ecological environment have become increasingly prominent, which has greatly accelerated the development and application of clean alternative fue...
