Problems solved by technology

The test results show that after anaerobic fermentation of straw, the energy retained in the biogas residue is greater than the energy transferred to the biogas, and the energy value of the straw biogas residue is high. However, the ash content of the straw after 20 days of fermentation is three times that of the unfermented straw, which may be It will enhance its slagging, and the calorific value of the briquette fuel prepared in this paper is only about 5.82% higher than that of the raw material, which cannot meet the needs of blast furnaces or places with high calorific value, and when used in small cooking stoves, there are problems of misfire and ignition. Long time, smoke pollution and other problems, low combustion efficiency, need to be modified to obtain high calorific value, anti-slagging new biomass briquette fuel

Embodiment Construction

[0013] An anti-slagging biomass briquette fuel, made of the following raw materials in parts by weight: corn stalks 100, wood shavings 20, peanut shells 18, magnesium carbonate 6, sodium dibutylnaphthalene sulfonate 0.4, citric acid 5, permanganate Potassium 3, manganese dioxide 0.9, sodium oxide 4, vermiculite 8, roasted siderite 19, appropriate amount of water.

[0014] The preparation method of a kind of anti-slagging biomass briquette, comprises the following steps:

[0015] (1) Add water and stir potassium permanganate until completely dissolved, add vermiculite and impregnate for 10-12 hours, take it out, dry it in an oven at 105°C and grind it into powder, add sodium oxide and citric acid and ultrasonically grind it for 10-15 minutes to obtain Accelerator;

[0016] (2) Soak roasted siderite in 5-10wt% hydrochloric acid solution for 1-2 hours, wash with hot water until there is no chloride ion, add water and ultrasonically treat at 80-100°C for 8-10 minutes, dry, add ca...

Abstract

The invention discloses an anti-slagging biomass briquette fuel. According to the invention, the pretreated corn straws are taken as a raw material for anaerobic fermentation for 10-20 days, so that mechanical endurance of the briquette fuel is increased, magnesium carbonate is taken as an anti-slagging agent, during a combustion process, the Mg element and elements such as Si, K, and Na which are inherent in the corn straws and are capable of slagging are subjected to a reaction, a novel compound K2Mg(SO4)2 is generated and provides anti-slagging performance to the briquette fuel, and the produced briquette fuel has the advantages of slagging resistance, firm combination and full combustion. A technical scheme can solve the processing problem of forestry and agricultural residues, and can alleviate the shortage problem of current fuel energy, so that the biomass briquette fuel has remarkable social benefit, and has obvious economic benefit.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to an anti-slagging biomass briquette fuel and a manufacturing method thereof. Background technique [0002] Biomass energy has become the fourth largest energy source in the world because of its renewable, abundant resources, and environmental friendliness. It is also the only clean renewable energy that can be transported and stored. It mainly uses modern biomass energy technology to convert agricultural waste and logging residues , livestock and poultry manure, municipal solid waste, domestic sewage and industrial organic wastewater and other raw materials are processed into end products such as biomass pellet fuel, biodiesel and biofuel ethanol. There is almost no SO2 emission in the later utilization process of biomass fuel, which reduces the harm of acid rain and greenhouse effect caused by the flue gas generated in the utilization process, which makes biomass energy hav...
