Embodiment 1

[0021] The present invention is achieved through the following technical solutions:

[0022] A method for preparing a composite high-energy biomass fuel rod, comprising the steps of:

[0023] (1) Put the straw powder into an oven and dry at 100°C for 20 minutes in the air atmosphere, take it out after drying and cool it quickly to obtain dry straw powder; After dilute hydrochloric acid solution is stirred and cleaned, carry out solid-liquid separation by suction filtration equipment; (3) directly add the sodium carbonate solution of 0.5mol / L to the wet filter residue cleaned in step (2), react 10 minutes under the above-mentioned solution boiling state, After the reaction, use suction filtration equipment to separate; (4) in parts by weight, 100 parts of the filtrate obtained by the separation of step (3) is transferred to the reactor, and then 5 parts of graphene airgel powder, mass fraction 12% Add 5 parts of ammonia water and 30 parts of absolute ethanol successively, stir...

Embodiment 2

[0034] A method for preparing a composite high-energy biomass fuel rod, comprising the steps of:

[0035](1) put the straw powder into an oven and dry at 200°C for 50 minutes in the air atmosphere, take it out after drying and cool it quickly to obtain dry straw powder; (2) dry plant ash with the same quality as the straw powder obtained in step (1) After dilute hydrochloric acid solution is stirred and cleaned, carry out solid-liquid separation by suction filtration equipment; (3) directly add the sodium carbonate solution of 1mol / L to the wet filter residue washed in step (2), react 15 minutes under the boiling state of above-mentioned solution, react Afterwards, separate with suction filtration equipment; (4) in parts by weight, 100 parts of the filtrate obtained by step (3) separation is transferred to the reactor, and then 10 parts of graphene airgel powder, mass fraction 14% Add 11 parts of ammonia water and 44 parts of absolute ethanol successively, stir evenly, then ad...

Abstract

The invention discloses a preparation method of a composite high-energy biomass fuel rod, belonging to the technical field of biomass fuels. According to the invention, a silicon dioxide aerogel is used for loading treatment of biomass straw powder and the like, thereby increasing the contact surface area of a fuel; inorganic and plant straw powders are organically combined for use; the produced biomass fuel rod is good in bonding degree, high in heat energy value, large in surface area, high in combustion efficiency, small in combustion pollution and beneficial for ecological environment construction, facilitates fuel storage, has sufficient combustion contact area and can prevent the fuel from damp and wetting-back; and thus, the combustion quality of the fuel is improved, and the problem of poor combustion heat energy value due to wetting of the fuel is overcome.

Description

technical field [0001] The invention belongs to the field of biomass fuels, and in particular relates to a method for preparing composite high-energy biomass fuel rods. Background technique [0002] Energy is inseparable from the sustainable survival and development of human beings, the construction and development of social economy and culture, and the health and prosperity of the earth's biosphere. At present, human beings mainly use disposable fossil fuels such as oil, natural gas and coal as energy supply. On the one hand, these energy sources face the problem of resource depletion; Serious pollution, ecological and ecological system balance damage and other problems, and hydrogen as a non-polluting sustainable supply of energy is gradually being recognized by scientists and society. Activated sludge is a general term for microbial groups and the organic and inorganic substances they are attached to. It is an aerobic biological treatment substance and is mainly used to ...
