Description
Technical field
The present invention relates to a kind of bamboo charcoal manufacturing process and its manufacturing equipment, and in particular to one kind continuously manufactures senior bamboo charcoal and produces
The manufacturing process and its manufacturing equipment of product.
Background technology
Bamboo charcoal is to adopt Phyllostachys pubescens Mazei ex H.de Lebaie for raw material, under the conditions of 400 DEG C of temperatures above completely cuts off carbonization product made by air dry distilling.
With the difference of firing temperature, the quality of bamboo charcoal and purposes difference are very big, and on the whole, the final firing temperature of retort process is got over
Height, the density of bamboo charcoal product, mechanical hardness, porosity and surface area are also bigger, when firing temperature is more than 1050 DEG C, can adopt
The senior bamboo charcoal with far infrared, anion and conducting function is made with bamboo wood, " Linesless charcoal " is commonly called as, is then commonly referred to as in Japan " standby
Long charcoal "（" Binchotan " has almost gone completely into the synonym of senior bamboo charcoal product at present）.
Traditional bamboo charcoal is produced using earth kiln device, and bamboo matter Binchotan then needs to fill using the earth kiln of particular design
Put, special charcoal kiln will be loaded after the Phyllostachys pubescens Mazei ex H.de Lebaie cutting newly cut, through carbonization, high temperature refinery, red charcoal kiln discharge, then lid is flooded with dry sandy soil
Method is stopped working, the senior Binchotan product needed for being eventually fabricated.Wherein high temperature refinery process procedure is to need most control technology and behaviour
Make the period of experience.
Take the existing long history of earth kiln device bamboo charcoal, but the production technology method has intrinsic, Wu Fatong
The defect crossed local improving and get rid of：
（1）Production process is seriously polluted, and flammable vapor product cannot realize effectively utilizes.Carbonization and refining process,
Substantial amounts of ash-laden gas can be discharged in carbonization process especially, although the bamboo vinegar in flue gas and wood tar can be big by condensation
Part removes, but incoagulability vapor phase contaminants（Hydrocarbon containing small molecule, carbon monoxide, methane and hydrogen etc. it is flammable into
Point）Then effectively cannot eliminate, also cannot effectively reuse（Reason is the rate of release extremely unstable of these gaseous products, it is impossible to
Carry out effectively storing and conveying）.
（2）Production efficiency is extremely low.Earth kiln technique can only take interval, by batch production mode manufacturing bamboo charcoal product,
Often complete stove bamboo charcoal firing and need to take 15 to 30 days, maximum earth kiln is also only capable of producing 30 tons or so of bamboo charcoal every time, puts down
Production efficiency is only 1～2 ton day.
（3）Unstable product quality.The bamboo charcoal of traditional earth kiln method production, its quality are completely controlled by furnace operation personnel's
Technical experience, impact of the anthropic factor to product quality are very big.
