Problems solved by technology

The earthen kiln is cheap, the refining temperature is high, and the density of bamboo charcoal is high, but the quality stability is poor and the yield is not high
[0011] Due to the limitations of equipment and technology for firing bamboo charcoal, it is difficult to obtain bamboo charcoal products with both density, porosity, crystallinity and other physical properties, which restricts the comprehensive functions and wide uses of bamboo charcoal products.

Embodiment 1

[0032] A preparation method of high-temperature microcrystalline bamboo charcoal, comprising the steps of:

[0033] (1) Put the bamboo raw material into the kiln from the feed port, and gradually dry the bamboo in the furnace with the heat of part of the bamboo combustion until it maintains spontaneous combustion;

[0034] (2) When the temperature in the furnace reaches 450°C, gradually reduce the smoke exhaust port and air inlet, and control the temperature of the kiln between 450-500°C to maintain the spontaneous combustion of bamboo and gradually carbonize;

[0035] (3) Adjust the air inlet and smoke exhaust port to raise the furnace temperature. When it rises to 850°C, send superheated steam from the water vapor and nitrogen gas supply pipes to activate the low-temperature bamboo charcoal. hold for 2 hours ;

[0036] (4) Slowly feed nitrogen gas from the water vapor and nitrogen gas supply pipes to make the medium-temperature bamboo charcoal in the furnace approach the s...

Embodiment 2

[0040] A preparation method of high-temperature microcrystalline bamboo charcoal, comprising the steps of:

[0041] (1) Put the bamboo raw material into the kiln from the feed port, and gradually dry the bamboo in the furnace with the heat of part of the bamboo combustion until it maintains spontaneous combustion;

[0042] (2) When the temperature in the furnace reaches 450°C, gradually reduce the smoke exhaust port and air inlet, and control the temperature of the kiln between 450-500°C to maintain the spontaneous combustion of bamboo and gradually carbonize;

[0043] (3) Adjust the air inlet and smoke exhaust port to raise the furnace temperature. When it rises to 850°C, send superheated steam from the water vapor and nitrogen gas supply pipes to activate the low-temperature bamboo charcoal. keep for 4 hours ;

[0044] (4) Slowly feed nitrogen gas from the water vapor and nitrogen gas supply pipes to make the medium-temperature bamboo charcoal in the furnace approach the s...

Abstract

The invention discloses a high-temperature microcrystalline bamboo charcoal and a preparation method thereof, comprising three main steps of low-temperature carbonization, medium-temperature activation and high-temperature crystallization. The invention effectively improves the far-infrared radiation rate, negative ion generation and adsorption function of bamboo charcoal products, and can meet the needs of the current market in the fields of using bamboo charcoal materials as environmental purification functional coatings, electromagnetic shielding functional materials, and health care functional textile material additives.

Description

Technical field [0001] The invention involves bamboo charcoal products, which is specifically a high -temperature micro -crystal bamboo charcoal and preparation method. Background technique [0002] Bamboo charcoal is a solid product obtained after the heat decomposition is generated at high temperature.Bamboo carbonization process is generally divided into five stages: dry, pre -carbonization, carbonization, forging and cooling. [0003] Dry bamboo: The hot flue gas produced by fuel combustion is smoked and dry. The temperature in the charcoal kiln is generally less than 150 ° C. It is mainly to remove the moisture in the bamboo material and make the shape of the bamboo material not easily change. [0004] Bamboo pre -carbonization: The temperature in the charcoal kiln is 150 ℃ ~ 270 ℃. [0005] Bamboo carbonization: The temperature in the charcoal kiln is 270 ° C to 360 ° C. Bamboo materials occur very fast to the heat decomposition, producing a large number of decomposition pr...
