Embodiment 1

[0024] A kind of biomass granular fuel dehydration carbonization treatment process, comprises the following steps:

[0025] 1) First select and clean the biomass raw materials, remove waste impurities that do not meet the production requirements, and carry out air-drying treatment on the biomass raw materials that meet the production requirements, so that the moisture content of the raw materials is controlled at 21-30%, and the impurities in the raw materials are removed. For external moisture, crush the air-dried raw materials and pass through a 260-mesh sieve to obtain raw material particles;

[0026] 2) Add (NH 4 )H 2 PO 4 Powder, the addition amount is 1 / 90 of the mass of raw material granules, mixed and stirred evenly to obtain mixed granules;

[0027] 3) Put the mixed particles in a tube furnace, raise the temperature from room temperature to 150°C under an inert atmosphere, at a heating rate of 4°C / min, keep warm for 8 hours, perform dehydration and stabilization pr...

Abstract

The invention provides a biomass particle fuel dehydration carbonizing treatment technology, and relates to the technical field of biomass particle fuel. The biomass particle fuel dehydration carbonizing treatment technology comprises the following steps that biomass raw materials are selected and cleared and subjected to air-drying treatment, external moisture in the raw materials is removed, andthe airing-dried raw materials are crushed to obtain raw material particles, (NH4)H2PO4 powder is added into the raw material particles and mixed and stirred evenly, the mixed particles are placed ina tube furnace, the mixed particles are subjected to dehydration stabilization pretreatment, after completing, the mixed powder is taken out, the mixed particles are subjected to carbonizing treatment by using a three-stage carbonization technology, cooled to 120 DEG C or below in a nitrogen atmosphere and taken out, carbonizing treatment is completed, and the biomass particle fuel is obtained. The situation of puffing adhesion can be effectively avoided in the carbonizing process of biomass through the biomass particle fuel obtained through dehydration carbonizing treatment, the carbonizingeffect is good, the carbon yield is good, and the energy yield is high. The activation energy required for combustion is low, and the integrated combustion property is good.

Description

technical field [0001] The invention relates to the technical field of biomass particle fuel, in particular to a dehydration and carbonization treatment process for biomass particle fuel. Background technique [0002] In recent years, with the rapid growth of my country's economy, the consumption of fossil fuels has increased year by year, and the problem of energy shortage has become increasingly serious. Biomass energy, as a renewable energy, is currently the fourth largest energy source in the world after coal, oil and natural gas. As a large agricultural country, our country is rich in types and quantities of biomass. Biomass mainly refers to straw other than grain and fruit in the process of agricultural and forestry production, lignocellulose such as trees, leftovers of agricultural product processing industry, agricultural and forestry waste, and poultry manure and waste in the process of animal husbandry. According to a huge survey, the potential of my country's bi...
