Embodiment 1

[0025] A preparation method of moso bamboo-based biomass particle fuel, comprising the steps of:

[0026] Step 1, cut down moso bamboo, cut the bamboo poles into moso bamboo sections, dry the bamboo leaves, and set aside;

[0027] Step 2, stuffing the dried bamboo leaves into the moso bamboo section with the moso bamboo section and the dried bamboo leaves in a ratio of 3:1 by weight;

[0028] Step 3, place the moso bamboo section in an externally heated dry distillation still, carry out dry distillation, and then cool naturally;

[0029] Step 4: Crush the moso bamboo section after dry distillation to obtain fine powder, then mix the fine powder and water evenly according to the weight ratio of 15:1, use a granulator to obtain granules, and dry them in the sun.

[0030] In the first step, the length of the obtained moso bamboo section is 10-20cm, and there is only one bamboo node in each section. In the first step, the diameter of moso bamboo is 3-10 cm. The temperature of c...

Abstract

The invention provides a preparation method of granular fuel taking phyllostachys heterocycla as a main raw material, and belongs to the technical field of natural fuel. The preparation method comprises steps as follows: step one, the phyllostachys heterocycla is chopped down, a bamboo pole is cut into phyllostachys heterocycla sections, and bamboo leaves are dried in the sun for standby; step two, the phyllostachys heterocycla sections are filled with the dried bamboo leaves according to the weight ratio of the phyllostachys heterocycla sections to the dried bamboo leaves of (3-5):1; step three, the phyllostachys heterocycla sections are placed into an externally heated retort for dry distillation and then naturally cooled; and step four, the phyllostachys heterocycla sections subjected to dry distillation are smashed to obtain fine powder, the fine powder and water are uniformly mixed according to the weight ratio of 15:(1-2), granules are prepared by a granulator and then dried in the sun, and the granular fuel is obtained. The phyllostachys heterocycla is subjected to dry distillation, juice in the bamboo leaves are distilled into the bamboo pole of the phyllostachys heterocycla and can be well combined with the bamboo pole, the forming rate of the prepared granules is high, the combustion efficiency is high and can be up to 17,000 J / g or above, and at the same time, the bamboo leaves are fully utilized.

Description

[0001] technical field [0002] The invention provides a preparation method of biomass-based fuel, in particular relates to a preparation method of granular fuel with moso bamboo as the main raw material, and belongs to the technical field of natural fuel preparation. [0003] Background technique [0004] With the development of society, primary energy sources such as coal and oil continue to decrease, and the pressure of the world's energy crisis is further increased. Various alternative energy sources are developing more and more rapidly, especially recyclable biomass energy is becoming more and more widely used. attention from all countries. The current biomass energy mainly includes: solid biomass fuel, liquid biomass fuel, and gas biomass fuel. [0005] Phyllostachys heterocycla (Carr.), scientific name Phyllostachys heterocycla (Carr.), belongs to Bamboo subfamily Bambusaceae, uniaxial scattered type. Evergreen tree-like bamboo plant with large stalks, up to 20 me...
