Problems solved by technology

[0004] Straw coal is usually made by adding water to the crushed straw. The disadvantages of the straw coal made in this way are mainly reflected in: it is not easy to form and store, because the straw is usually crop straw, leaves, dead branches, sawdust, weeds, etc. , the water content in the raw material is relatively large, and the straw coal made after simple crushing is easy to deform, and at the same time it is easy to deteriorate outdoors, which is not conducive to storage; the combustion is not sufficient, and due to the large water content in the raw material itself, a certain amount of If there is too much water, the combustion of straw coal is not sufficient, and the energy loss is large. At the same time, the combustion is not sufficient, and the value of full utilization is not achieved.

Embodiment 1

[0032] A method for preparing a novel environment-friendly high-combustion value straw coal, which comprises the following steps:

[0033] 1) 22 parts of corn stalks are pulverized in a pulverizer to reach 60 mesh;

[0034] 2) put the stalk powder that pulverizes into drying machine and dry, ensure that the stalk moisture content is at 6%;

[0035] 3) Take out the dried straw, first add 10 parts of slag, 2 parts of magnesium hydroxide, 5 parts of silicon dioxide, 2.5 parts of calcium carbonate, and 3 parts of ethyl acetate into a mixer at 40 °C, and mix evenly for 3 hours to obtain a mixed powder;

[0036] 4) Transfer the mixed powder obtained in 3) to a mixer, add 80 parts of absolute ethanol, and stir at 100 °C for 1 h to obtain a solidified powder;

[0037] 5) Put the above-mentioned mixed powder into a compression molding machine for compression molding to make granular fuel;

[0038] 6) Cooling, sieving and packaging the obtained granular fuel.

Embodiment 2

[0040] A method for preparing a novel environment-friendly high-combustion value straw coal, which comprises the following steps:

[0041] 1) 38 parts of corn stalks are pulverized in a pulverizer to reach 60 mesh;

[0042] 2) put the stalk powder that pulverizes into drying machine and dry, ensure that the stalk moisture content is at 6%;

[0043] 3) Take out the dried straw, first add 10 parts of slag, 2 parts of magnesium hydroxide, 5 parts of silicon dioxide, 2.5 parts of calcium carbonate, and 3 parts of ethyl acetate into a mixer at 40 °C, and mix evenly for 3 hours to obtain a mixed powder;

[0044] 4) Transfer the mixed powder obtained in 3) to a mixer, add 80 parts of absolute ethanol, and stir at 100 °C for 1 h to obtain a solidified powder;

[0045] 5) Put the above-mentioned mixed powder into a compression molding machine for compression molding to make granular fuel;

[0046] 6) Cooling, sieving and packaging the obtained granular fuel.

Abstract

The invention discloses a novel environmentally friendly high-fuel-value straw coal. The novel environmentally friendly high-fuel-value straw coal comprises straws, slag, a flame accelerator, oxide, a sulphur-fixing agent and organic ester. The invention further discloses a preparation method of the novel environmentally friendly high-fuel-value straw coal. The novel environmentally friendly high-fuel-value straw coal is simple in formula, and has the advantages that preparation of fuel is optimized, operation is facilitated, energy consumption is reduced, and the cost is saved; the fuel value and the flashing point are high; the stable period is long and can be maintained for 36-48 months; and the discharge amount is small, the novel environmentally friendly high-fuel-value straw coal is clean and environmentally friendly, and air is not polluted.

Description

technical field [0001] The invention relates to a novel environment-friendly high-combustion value straw coal and a preparation method thereof. Background technique [0002] my country's annual biomass production is very large, but the utilization of biomass is extremely small, and 90% of the country's straw is directly burned, landfilled or directly discarded in farmland for biodegradation every year, and this part of resources is wasted. [0003] Energy is the basis for the development of the national economy. At present, with the development and progress of society, energy consumption is greater. Due to the serious shortage of fossil fuels and the high pollution of the environment, and the impact of the international situation and regional conflicts on fossil fuels, the supply of fossil fuels is becoming increasingly tight. Many oil, coal, and natural gas producing countries use this as a strategic weapon to control the international market and enhance their national in...
