Embodiment 1

[0011] Production raw materials and methods: Slice and crush fresh rose stalks and emperor bamboo grass to less than 10mm, then squeeze and separate them into solid straw powder and juice, dry the solid straw powder to a water content of less than 20%, and concentrate the juice to a water content of 50% To obtain the concentrate, fully mix the two (solid straw powder to concentrate) by weight ratio of 100:5, extrude and granulate with a flat die granulator to make a briquette with a diameter of 5-12mm and a length of 12-15mm. Then send it to the cooling and screening machine for cooling and screening, so that the temperature of the particles is ≤40°C, and the particle forming rate is 95%. After testing, the density of the forming fuel is 1.2g / mL.

Embodiment 2

[0013] The production raw materials and methods are as follows: fresh tobacco stalks, mulberry trees and emperor bamboo grass are sliced ​​and crushed to less than 10mm, separated into solid straw powder and juice by pressing, the solid straw powder is dried until the water content is below 20%, and the juice is concentrated to the water content About 30% of the concentrated solution, fully mix the two (solid straw powder to concentrated solution) at a weight ratio of 100:3.5, extrude and granulate with a flat die granulator, and make 5-12mm in diameter and 12-15mm in length The molded fuel is then sent to the cooling and screening machine for cooling and screening, so that the particle temperature is ≤40°C, and the pellet forming rate is 96%. After testing, the density of the molded fuel is 1.1g / mL.

Embodiment 3

[0015] Production raw materials and methods: fresh rose stalks, tobacco stalks and Eupatorium adenophorum are sliced ​​and crushed to less than 10 mm, separated into solid straw powder and juice by pressing, solid straw powder is dried to a water content of less than 20%, and the juice is concentrated to For the concentrated solution with a water content of about 40%, fully mix the two (solid straw powder to concentrated solution) at a weight ratio of 100:4, extrude and granulate with a flat-die granulator, and make 5-12mm in diameter and 12-2mm in length. The 15mm shaped fuel is then sent to the cooling and screening machine for cooling and screening, so that the particle temperature is ≤40°C, and the particle forming rate is 95%. After testing, the density of the shaped fuel is 1.2g / mL.

Abstract

The invention relates to plant polygenic biomass particle fuel and a preparation method thereof. Plant mixed straw powder of rose flower, mulberry tree, tobacco, purple eupatorium japonicum, hybrid giant napier is completely mixed with pressed separating condensating liquid thereof, and then is pressed to be strip or column particles. The water content of the plant mixed straw powder is below 20 percent, and the particle size is below 10 mm; the water content of the pressed separating condensating liquid is 30-50 percent, and the weight proportion of the plant mixed straw powder and the pressed separating condensating liquid is 100:3-6. The invention utilizes the pressed separating condensating liquid of plant mixed straws of the rose flower, the mulberry tree, the tobacco, the purple eupatorium japonicum, the hybrid giant napier as adhesive to be mixed with the solid straw powder so as to enable the forming in the particle preparation to be easy and the particle structure to be compact.

Description

technical field [0001] The invention relates to the technical field of solid biomass energy, in particular to a grass-plant composite-based biomass particle fuel and a preparation method thereof. Background technique [0002] With the continuous development of the global economy, human demand for energy continues to increase, while energy resources such as oil, natural gas, and coal are continuously decreasing. The development of biomass renewable energy has become a hot spot of concern from all walks of life. my country is a big country of solid biomass energy. Biomass fuels such as various crop straws and forest wastes are extremely rich, but they have not been effectively utilized for a long time. In recent years, due to the shortage of energy resources and the increasingly prominent problems of ecological environment protection, the development of solid biomass briquettes has attracted people's attention. The cold press molding of biomass pellet fuel using various crop ...
