preparation example Construction

[0019] figure 1 A schematic flow diagram of the charcoal preparation method of the present invention is shown in . Such as figure 1 As shown, the preparation method includes: after the raw materials are prepared, the raw materials are pulverized, dried, extruded, and carbonized to obtain a charcoal product. The raw materials are one or more of sawdust, branches, rice husks, peanut shells, walnut shells, Eupatorium adenophorum and crop straws. Further preferably, the weight ratio of the raw materials is: 10-20 parts of sawdust, 10-20 parts of branches, 10-30 parts of rice husks, 10-20 parts of peanut shells, 10-30 parts of walnut shells, 10 parts of Eupatorium adenophorum -30 parts and a mixture of 10-30 parts of crop straw.

[0020] The branches used in the raw materials can be branches of any tree species, such as pine branches, mulberry branches, eucalyptus branches and the like. The crop straw used may be any crop straw, such as corn straw, wheat straw, sorghum straw an...

Embodiment 1

[0028] A kind of preparation method of charcoal comprises in the present embodiment:

[0029] A mixture of 10 parts of sawdust, 15 parts of pine branches, 30 parts of rice husks, 20 parts of peanut shells, 15 parts of walnut shells, 20 parts of Eupatorium adenophorum and 10 parts of corn stalks is selected as raw materials, and the raw materials are pulverized to The particle size is 6mm. Dry the pulverized particles at 200°C for 3 hours to make the moisture content reach 20%, extrude and cut them at 160°C to obtain firewood rods, ignite the firewood rods in a carbonization furnace, and after 20 hours The temperature in the furnace was raised to 330° C., and charcoal was obtained after closing the carbonization furnace for 3 days.

Embodiment 2

[0031] Select a mixture of 15 parts of sawdust, 10 parts of eucalyptus branches, 20 parts of rice husks, 10 parts of peanut shells, 30 parts of walnut shells, 10 parts of Eupatorium adenophorum and 30 parts of wheat straw as raw materials, and crush the raw materials to The particle size is 8mm, and the crushed particles are dried at 250°C for 2 hours to make the moisture content reach 12%, extruded and cut at 200°C to obtain a fuel rod, and the fuel rod is ignited in a carbonization furnace, and after 25 hours The temperature in the furnace was raised to 350° C., and charcoal was obtained after closing the carbonization furnace for 4 days.

Abstract

The invention relates to a preparation method of charcoal and the charcoal. The preparation method comprises the following steps: using sawdust, branches, rice husks, peanut shells, walnut shells, ageratina adenophora, and wastes such as crop straw as raw materials, smashing, drying, performing extrusion forming, carbonizing and the like, and finally obtaining the rodlike charcoal. The charcoal has the advantages of being long in burning time, larger in heating value, smokeless and odorless in the burning process, clean and environment-friendly, and having low possibility of spark flying in the burning process.

Description

technical field [0001] The invention relates to a preparation method of charcoal and charcoal, in particular to a preparation method of clean and environment-friendly charcoal and the charcoal. Background technique [0002] Charcoal is an indispensable raw material for my country's industry, agriculture, animal husbandry, metallurgy and other industries. With the rapid development of my country's economy, the demand for charcoal has also become a rapid growth trend. How to alleviate the current situation without destroying forest resources? The demand for charcoal is an urgent problem to be solved. [0003] my country is a large agricultural production country. The annual production of crop straw is about 10 billion tons, of which only 20-30% has been effectively used, and the rest has been treated as garbage or burned, causing serious environmental pollution. Every year, billions of tons of branches, sawdust, and rice husks are thrown away as garbage, which is a serious was...
