Embodiment 1

[0032] Combustible plant materials (mainly referring to the roots or stems or branches or bark or shells of various plants, such as fast-growing forest trees that need to be felled regularly, tree roots, bark, branches, straw or coconut shells of various plants, etc. ) are collected as raw materials, and the raw materials are processed through the following steps in sequence:

[0033] (1) Pulverization: through pulverization, the raw materials are formed into powdery granular materials with a particle size below 2mm;

[0034] (2) Drying: Dry the crushed materials, first through preliminary drying so that the moisture content of the materials is about 12%, and an appropriate deviation is allowed; then put the preliminary dried materials into the storage tank , let the dry hot air flow of about 60°C into the storage tank, so that the dry hot air will drive the material to be output from the material outlet on the tank body to the conveyor belt outside the tank body, and then the...

Embodiment 2

[0038] Combustible plant materials (mainly referring to the roots or stems or branches or bark or shells of various plants, such as fast-growing forest trees that need to be felled regularly, tree roots, bark, branches, straw or coconut shells of various plants, etc. ) are collected as raw materials, and the raw materials are processed through the following steps in sequence:

[0039] (1) Pulverization: through pulverization, raw materials are formed into powdery granular materials with a particle size below 1mm;

[0040](2) Drying: Dry the crushed materials, first through preliminary drying so that the moisture content of the materials is about 20%, and an appropriate deviation is allowed; then put the preliminary dried materials into the storage tank , let the dry hot air flow of about 80°C into the storage tank, so that the dry hot air will drive the material to be output from the material outlet on the tank body to the conveyor belt outside the tank body, and then the mate...

Embodiment 3

[0044] Combustible plant materials (mainly referring to the roots or stems or branches or bark or shells of various plants, such as fast-growing forest trees that need to be felled regularly, tree roots, bark, branches, straw or coconut shells of various plants, etc. ) are collected as raw materials, and the raw materials are processed through the following steps in sequence:

[0045] (1) Pulverization: through pulverization, the raw materials are formed into powdery granular materials with a particle size below 1.5mm;

[0046] (2) Drying: Dry the crushed materials, first through preliminary drying so that the moisture content of the materials is about 17%, and an appropriate deviation is allowed; then put the preliminary dried materials into the storage tank , let the dry hot air flow of about 70°C into the storage tank, so that the dry hot air will drive the material to be output from the material outlet on the tank body to the conveyor belt outside the tank body, and then t...

Abstract

The invention relates to a production process of an environmental-protection plant energy particle fuel, which is characterized by collecting combustible plant materials as raw materials and then sequentially processing the raw materials by the following steps of: (1) pulverizing: the raw materials are pulverized into powdery particle materials with the particle size less than 2 mm; (2) drying: the pulverized materials are dried so that the water content of the materials is 12%-20% by drying; and (3) extrusion molding: extrusion molding is carried out to the dried materials so that the materials form a solid particle fuel with the density of 1.0-1.4 g/cm<3> through extrusion molding. The invention can be used for processing various combustible plant materials comprising agricultural or forestall wastes and the like into high-efficiency combustible solid fuel particles, thereby solving the problem of considerably increased agricultural (forestall) wastes at present, also relieving the current situation of increasing energy shortage at present and being beneficial to environmental protection and energy saving.

Description

technical field [0001] The invention relates to a production process of environmentally friendly plant energy particle fuel. Background technique [0002] With the expansion of agricultural mechanization and scientific planting, on the one hand, the output of agricultural and forestry crops has increased, and agricultural (forestry) waste has increased significantly; on the other hand, the living standards of farmers have improved rapidly. It is replaced by "clean" energy such as burning biogas and coal gas, and the use of traditional methods is relatively reduced. At present, the traditional methods used to solve the massive increase of agricultural (forestry) wastes are mainly the following two: one is to use the landfill method, which will cause a large amount of land to be uncultivable every year; Burning on the spot, every summer and autumn, because the pollution caused by farmers burning straw and other agricultural and forestry wastes has become an important source o...
