Definitions
- the invention relates to a method for making bio-coal by regenerating plant waste.
- sulfur dioxide SO2
- SO2 sulfur dioxide
- the residue left over from coal after complete combustion is called ash, extrinsic ash and intrinsic ash.
- the external ash comes from the rock fragments in the roof and the interlayer, and it has a lot to do with the reasonableness of the coal mining method. Most of the external ash can be removed by sorting.
- Intrinsic ash is the inorganic matter contained in the original coal-forming plant itself. The higher the intrinsic ash, the poorer the selectivity of coal. Ash is a harmful substance.
- the increase of ash content in steam coal will reduce the calorific value and increase the amount of slag discharge, and the coal will be prone to slagging; generally, for every 2% increase in ash content, the calorific value will decrease by about 100kcal/kg.
- the present invention provides a method for producing bio-coal, which uses discarded plant parts as raw materials to produce bio-coal with high calorific value, low emission and low price.
- the present invention achieves the above object like this:
- the preparation method of biological coal comprises the following steps:
- the sintering furnace stops heating and maintains negative pressure, the molten raw material cools down and crystallizes into bio-coal crystals.
- the raw materials before placing the raw materials into the sintering furnace in step S1-1, the raw materials need to be dried to control the water content of the raw materials within 15%.
- step S2-3 the solidified bio-coal is also cut into shape, and the bio-coal crystal waste generated by cutting is recycled and re-fed to step S2-2 after mixing the crystal powder. Formed in one go.
- the negative pressure is minus one atmosphere.
- the discarded plant parts include palm, coconut, corn, canola, rice, barley, wheat branches, leaves, stems, roots, seed shells, and waste wood.
- the discarded plant parts include seaweed and seaweed.
- the finished product of bio-coal is oval.
- the preparation method of biological coal comprises the following steps:
- the waste parts of the plants come from a wide range of sources, such as terrestrial annual or perennial plants, such as branches, leaves, stems, roots, and seed shells of palm, coconut, corn, canola, rice, barley, and wheat , waste wood, etc., can also use plants growing in the ocean, such as seaweed and seaweed, etc., so the source of raw materials is very extensive, abundant and low in cost.
- sources such as terrestrial annual or perennial plants, such as branches, leaves, stems, roots, and seed shells of palm, coconut, corn, canola, rice, barley, and wheat , waste wood, etc.
- the raw materials need to be dried, and the water content of raw materials needs to be controlled within 15%.
- the present invention preferably uses negative pressure, and the negative pressure is minus one atmospheric pressure, that is, a vacuum environment.
- the sintering temperature needs to be adjusted or selected according to the characteristics of different raw materials.
- a lower sintering temperature can be selected for raw materials with relatively soft materials and smaller sizes, such as plant leaves, straw and other materials. The lower temperature is enough to completely melt such raw materials.
- a higher temperature should be selected so that the raw material can be fully melted.
- the main element of the raw material is hydrocarbon, which will be carbonized first under vacuum or high temperature. After a certain period of time, the carbonized substance will melt and be sintered after exceeding its melting point.
- the sintering furnace stops heating and maintains negative pressure, the molten raw material cools down and crystallizes into bio-coal crystals.
- the overall shape of the bio-coal crystals obtained by sintering is similar to that of the raw materials, so it is very unfavorable for transportation and storage, and the stacking of bio-coal crystals may affect the combustion effect during combustion. To this end, it is also necessary to carry out a shaping operation on the bio-coal crystals.
- the operation steps are as follows:
- the molded mixture is placed in an oven and heated to 90-200°C for curing.
- the curing temperature depends on the curing temperature of the glue used. Due to factors such as mold clamping accuracy and the amount of mixture added, the solidified bio-coal will have burrs, etc., so it needs to be cut and shaped.
- the bio-coal crystal waste produced by cutting and molding is recovered and re-fed into step S2-2, where the crystal powder is mixed and then re-molded.
- the bio-coal product is oval in shape. When this shape is used, an appropriate gap can still be reserved between the bio-coal products in the stacked combustion chamber, so that air can circulate in the gap, which is more conducive to the combustion.
- the sources of discarded plant parts mentioned above can be very wide, and can be any discarded parts of annual or perennial plants. Some specific examples are given below to illustrate: Land plants, including palm, coconut, corn, mustard Flower seeds, rice, barley, wheat branches, leaves, stems, roots, seed shells, waste wood; marine plants, including seaweed and seaweed, etc.

Abstract
Procédé de production de biocharbon, dans lequel des parties de plantes éliminées sont utilisées comme matière première, un frittage est réalisé sous vide et dans un environnement à haute température, un biocharbon présentant un pouvoir calorifique élevé, de faibles émissions et un faible prix est produit. Par comparaison avec du charbon actuellement utilisé, des gaz polluants, tels que le dioxyde de soufre, le sulfure d'hydrogène, l'oxyde nitrique et analogues, qui sont générés au cours d'une combustion peuvent être considérablement réduits, de sorte que la combustion est plus propre. Selon un autre aspect, le pouvoir calorifique généré par la combustion du produit fini obtenu est de 15 à 20 % plus élevé que le pouvoir calorifique du charbon, de sorte que ledit procédé peut être largement appliqué à la fusion de l'acier, à la génération d'énergie thermique et analogues et représente une source d'énergie substitut du charbon plus idéale et respectueuse de l'environnement.
