Problems solved by technology

The new type of bio-renewable energy is developing rapidly, but the current biomass pellets are susceptible to moisture, which not only increases the weight and affects the combustion effect, but also is prone to mildew due to the biomass raw materials. Slag, those skilled in the art urgently need to develop a new type of moisture-proof high-energy biomass fuel

Embodiment 1

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

[0022] Step 1. Hydrothermal treatment of modified activated sludge:

[0023] In parts by weight, water was added to 93 parts of modified activated sludge to make the water content 71.2%, and 138 parts of plant straw powder and 5.4 parts of sodium ethylenediamine di-o-phenyl macroacetate were pulverized to 400 mesh, Grind 31 parts of charcoal slag powder to 300 meshes, prepare 20 parts of edible alkaline water with a mass fraction of 5% for later use; mix the crushed plant straw powder and ethylenediamine di-o-phenyl macroacetate mixture with edible alkaline water evenly , to obtain mixture A after stacking for 10 hours; mix mixture A with the obtained modified activated sludge, charcoal slag powder, and active agent evenly, and then heat it in a microwave hydrothermal kettle at 200°C for 1.5~2 hours while stirring, and then cool down. After reaching 105°C, keep warm for another 0.8h, and obt...

Embodiment 2

[0034] The present invention is achieved through the following technical solutions:

[0035] Step 1. Hydrothermal treatment of modified activated sludge:

[0036] In parts by weight, water was added to 82 parts of modified activated sludge to make its moisture content 67.3%, and 115 parts of plant straw powder and 2.1 parts of sodium ethylenediamine di-o-phenyl macroacetate were pulverized to 400 mesh, Grind 22 parts of charcoal slag powder to 300 mesh, and prepare 15 parts of edible alkaline water with a mass fraction of 2% for later use; mix the crushed plant straw powder and ethylenediamine di-o-phenyl macroacetate mixture with edible alkaline water evenly , to obtain mixture A after stacking for 6 hours; mix mixture A with the obtained modified activated sludge, charcoal slag powder, and active agent, and then heat it at 180°C in a microwave hydrothermal kettle for 1.5 hours while stirring, and then cool it down. After 100°C, keep warm for 0.8h, and after cooling, obtain ...

Abstract

The invention discloses a preparation method of a moisture-proof high-energy biomass granular fuel, belonging to the technical field of biomass fuels. The moisture-proof high-energy biomass granular fuel is prepared by using activated sludge to carry out hydrothermal treatment on biomass raw materials plant straw powder and the like, using digested sludge to position and synthesize energetic polymers, and after the components are mixed, granulating, and organically combining the biomass energy activated sludge, nitrated sludge and the plant straw powder, and the produced biomass granular fuelhas good adhesion, high calorific value, high combustion efficiency and small combustion pollution, the construction of the ecological environment is facilitated, by proper addition of some charcoal slag powder, the combustion effect can be enhanced, and the combustion heat value can be improved. In addition, through combination and matching of various raw materials including the nitrated sludge,an activator, polyethylene glycol nitrate and the like in the fuel, the storage of the fuel can be facilitated, the fuel is prevented from being affected with damp and moisture regain, the combustionquality is further improved, and the problem of poor combustion heat value caused by the fuel being affected with damp can be simultaneously avoided.

Description

technical field [0001] The invention belongs to the field of biomass fuels, in particular to a method for preparing moisture-proof high-energy biomass particle fuels. 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 tr...
