Embodiment 1

[0037] A high-efficiency and environmentally friendly biomass fuel includes the following raw materials in parts by weight: 20 parts of pine and cypress sawdust, 30 parts of pine bark, 10 parts of pine needles, 10 parts of weeds, 8 parts of straw and 8 parts of peanut shells;

[0038] This kind of highly efficient and environmentally friendly biomass fuel is prepared by the following steps:

[0039] Step 1. After cleaning and sieving the raw materials in parts by weight of the formula, they are respectively added to a crusher for crushing treatment to obtain a crushed mixture with a particle size of 5 mm; the crushed mixture is dried to make the moisture content 9.5wt%;

[0040] Step 2. Put the above-mentioned dried pulverized mixture in a microwave high-temperature sintering furnace. Under the protection of nitrogen, start to heat up from 200°C, and raise the temperature to 800°C at a heating rate of 20°C / min, and keep it for 30 minutes to obtain the initial fuel Taste;

Abstract

The invention discloses a high-efficiency and environment-friendly biomass fuel and a preparation method thereof, which comprises the following raw materials: pine and cypress sawdust, pine bark, pine needles, weeds, straw and peanut shells; it is prepared by the following steps: step 1, cleaning the formula raw materials, Screening, crushing and drying; step 2, high-temperature carbonization of the pulverized mixture; step 3, granulating and drying the primary fuel product; the granulation drying equipment includes a bottom plate, a granulation motor, a reducer, The granulation forming mechanism, the drying lifting mechanism and the lifting motor, the granulation motor is installed and fixed on the upper side of the base plate, the reducer is installed and fixed in the center of the upper surface of the base plate, the granulation forming mechanism is located above the reducer, and the drying and lifting mechanism is located On the other side of the upper surface of the bottom plate, the lifting motor is installed on the top of the drying lifting mechanism; the invention solves the problem of poor quality of biomass fuel in the prior art.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel, and in particular relates to a high-efficiency and environment-friendly biomass fuel and a preparation method thereof. Background technique [0002] Biomass fuel is a distributed renewable energy that is green, low-carbon, and environmentally friendly. It is an important measure to replace fossil energy for heating and prevent and control air pollution. It can also build a renewable energy system in cities and towns, and has become the core of current bioenergy research. The most prominent difference between biomass and petrochemical resources is their impact on the environment: when biodegraded, most of the chemicals it releases are returned to the environment to be reused by organisms; Buried underground, before being mined and utilized, it can exist more stably and has less impact on the environment, but when it burns, a large amount of substances such as sulfur and heavy metals deposited...
