Embodiment 1

[0020] (1) Make shavings and sawdust from rubber wood waste according to the routine, and then dry the shavings and sawdust at 80°C until the moisture content of the shavings and sawdust is 6%;

[0021] (2) Prepare the shavings and sawdust obtained in step (1) according to the following components by mass percentage:

[0022] Wood shavings 35%, sawdust 65%;

[0023] (3) After mixing the components in step (2), hot-press the rod at a temperature of 750°C and a pressure of 2800kgf to obtain a rod carbon; ensure that the shaft of the rod is smooth when making the rod;

[0024] (4) Put the stick charcoal obtained in step (3) in a sealed kiln, heat it outside the sealed kiln, and make the temperature of each position in the sealed kiln reach 950-980°C, and heat it at 950-980°C 3 days to achieve carbonization, and then stop heating, so that the stick charcoal is naturally carbonized in a sealed kiln for 3 days, so that the carbon stress of the stick charcoal is uniform;

Embodiment 2

[0028] (1) Make shavings and sawdust from rubber wood waste according to the routine, and then dry the shavings and sawdust at 81°C until the moisture content of the shavings and sawdust is 7%;

[0029] (2) Prepare the shavings and sawdust obtained in step (1) according to the following components by mass percentage:

[0030] Wood shavings 38%, sawdust 60%, carbon powder 2%;

[0031] Wherein, carbon powder is the waste charcoal that surface is not smooth, loose and easily broken in the mechanism charcoal gained in embodiment 1;

[0032] (3) After mixing the components in step (2), hot-press the rod at a temperature of 700°C and a pressure greater than 2500kgf to obtain a rod carbon; ensure that the shaft of the rod is smooth when making the rod;

[0033] (4) Put the stick charcoal obtained in step (3) in a sealed kiln, heat it outside the sealed kiln, and make the temperature of each position in the sealed kiln reach 950-980°C, and heat it at 950-980°C 3 days to achieve carb...

Embodiment 3

[0037] (1) Make shavings and sawdust from rubber wood waste according to the routine, and then dry the shavings and sawdust at 80-82°C until the moisture content of the shavings and sawdust is 8%;

[0038] (2) Prepare the shavings and sawdust obtained in step (1) according to the following components by mass percentage:

[0039] Wood shavings 45%, sawdust 55%;

[0040] (3) After mixing the components in step (2), hot-press the rod at a temperature of 800°C and a pressure of 3000kgf to obtain a rod carbon; ensure that the shaft of the rod is smooth when making the rod;

[0041] (4) Put the stick charcoal obtained in step (3) in a sealed kiln, heat it outside the sealed kiln, and make the temperature of each position in the sealed kiln reach 950-980°C, and heat it at 950-980°C 3 days to achieve carbonization, and then stop heating, so that the stick charcoal is naturally carbonized in a sealed kiln for 3 days, so that the carbon stress of the stick charcoal is uniform;

Abstract

The invention discloses a method for producing machine--made charcoal from rubber timber waste. The rubber timber waste is prepared into wood shavings and saw dust through a conventional method, the wood shavings and the saw dust are dried until the water content is 6-8%, carbon powder, the wood shavings and the saw dust are mixed and pressed in a hot mode to prepare bars, bar carbon is placed into a seal kiln, heated at the temperature of 950 DEG C-980 DEG C and kept at the temperature for 3 days to be carbonized, heating is stopped, and the bar carbon is naturally carbonized for 3-4 days in the seal kiln, so that carbon stress of the bar carbon is uniform; the bar carbon is moved from the seal kiln to the outside to be aired for 5-6 days, and temperature and humidity can be balanced with the outside to obtain the machine--made charcoal. The machine-made charcoal is high in packing degree, large in density and high in heat quantity, the density can reach 1.1-1.2 g/cm<3>, the content of fixed carbon is larger than 80%, the combustion value is larger than 7500 kcal, the combustion time is longer than 4 h, the ash content is smaller than 4%, and the water content is smaller than 6%.

Description

technical field [0001] The invention relates to a method for producing mechanical charcoal from rubber wood waste, and belongs to the technical field of biomass recycling. Background technique [0002] Mechanism charcoal, also known as mechanism charcoal, salary rod, artificial charcoal, regenerated charcoal, smokeless clean charcoal, is a carbonaceous rod made of wood scraps. Originated in Japan, it was introduced to the mainland through Taiwan. The raw materials come from a wide range of sources, including rice husks, peanut shells, cotton husks, corncobs, corn stalks, sorghum stalks, bean stalks, sawdust, wood chips, shavings, pine shells, coconut shells, etc. It can be used as raw material to produce stick charcoal, with sawdust, shavings, bamboo chips and rice husk being the best. The market for machine-made charcoal is vast. It is used in restaurants as barbecue charcoal. The density of machine-made charcoal is more than three times that of charcoal, and it burns with...
