Abstract
The present invention discloses a method for vacuum calcination of bamboo charcoal in a tunneling kiln, steps are as follows: 3-5 years old mao bamboos are cut into segments according to specifications, then the segments are packed into a bowl, and dried in a drying hole at 0 DEG C-350 DEG C, a bamboo vinegar liquid is extracted in the drying process, after the drying, the segments are buried and filled into rice husks or refractory materials for vacuum treatment, then fired at 1000 DEG C to 1300 DEG C for 36 hours to 60 hours, and cooled to obtain the bamboo charcoal, and the bamboo charcoal is calcined in the tunneling kiln in vacuum way, the bamboo charcoal can be extensively developed in south places rich in mao bamboos, and the bamboo charcoal can play a unique role in all fields, and can play inestimable value especially in environmental protection. The charcoal yield can reach 30%-45%, compared with the traditional process, the charcoal yield is improved by 10%-15%, the method is simple and easy in temperature control, product quality is stable, the failure rate is reduced, the method is environmentally-friendly and energy-saving, can effectively use lands, has a cycle of 3-5 years, and continuous development can be achieved.
Description
Technical field
The present invention relates to a kind of method of tunnel furnace vacuum calcining bamboo charcoal.
Background technology
At present, China's bamboo carbon mode of production perplexs this product and breaks through, although aboundresources, production technique still adopts old-fashioned technique, application earth kiln production method, and production quantity, produces carbon rate, and quality product is subject to affecting in various degree can not continuous seepage.The effect of production in enormous quantities scale can not be reached, waste energy again.Environmental protection is had a strong impact on, and novel appts also cannot improve output, the developing of puzzlement bamboo charcoal product and development.Carbonization method and the direct firing process of earth kiln two kinds of bamboo charcoal preparation methods are mainly contained in prior art.
Carbonization method can use predry to water ratio to be the bamboo wood of 20% ~ 25%, also can use the bamboo wood without predry, but to use the bamboo wood through predry to be good.Owing to substantially there is not bamboo charcoal problem of oxidation in sintering procedure, therefore bamboo charcoal yield is higher, is generally about 25%, Gao Zheke and reaches 35%.But refining temperature is carried not high, affect bamboo charcoal density; Retort volume is little, and bamboo charcoal yields poorly.
Earth kiln firing process has predrying, dry, the pre-charing of sootiness, charing, the calcining stage such as (refining), naturally cooling usually.There is different temperature in each stage, and sootiness pre-drying phase is 60 ~ 100 DEG C, and drying stage is 100 ~ 150 DEG C, and pre-carbonization stage is 150 ~ 270 DEG C, and carbonization stage is 270 ~ 450 DEG C, and calcination stage is 450 DEG C to about 1000 DEG C.From the process that earth kiln is made charcoal, the temperature in each stage and charing rate " observe nasil " by operator, and one is the change observing chimney and wicket smoke outlet cigarette; Two is determine by hearing smoke.The fresh mao bamboon of earth kiln, generally outdoor placement about a week, putting into kiln, to carry out sootiness predrying, and approximately want 1 week, and also need one week when naturally cooling to kilneye temperature 50 ~ 60 DEG C, kiln discharge generally also takes 2 days.So generally take 25 ~ 30 days from loading of kiln to going out charcoal, bamboo charcoal yield is generally about 20%.But the amount of later stage oxidizing fire can lower than 20%, even lower (bleed because of air or air capacity enters excessive).Earth kiln low cost, refining temperature is high, and bamboo charcoal density is large, but quality stability is poor, and yield is not high.
Therefore, prior art needs further improvement and develops.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of method of tunnel furnace vacuum calcining bamboo charcoal, under the prerequisite ensureing bamboo charcoal burning quality, carry high carbon output rate.
For solving the problems of the technologies described above, technical solution of the present invention comprises:
A method for tunnel furnace vacuum calcining bamboo charcoal, it comprises the following steps:
A, by the setation bamboo of 3-5 fell after be cut into multiple mao bamboon section according to alms bowl (kiln) the tool specification in kiln car, mao bamboon section is put into the alms bowl tool of kiln car, utilize residual heat of tunnel kiln 0 DEG C of-350 DEG C of condition in tunnel furnace drying hole under, carries out drying;
B, dried kiln car is carried out vacuum-treat, with rice husk or refractory materials mao bamboon in alms bowl tool buried and enter the stage of burning till, carry out the process of vacuum kiln;
C, under 1000 DEG C of-1300 DEG C of conditions, fire 36 hours-60 hours, obtain bamboo charcoal by after the kiln car cooling in tunnel furnace.
Described method, wherein, concrete also the comprising of above-mentioned steps A: be all furnished with recycling pipeline in each kiln car, recycling pipeline is for extracting the bamboo vinegar liquid produced in mao bamboon drying process.
Described method, wherein, above-mentioned steps C also comprises: by bamboo charcoal vacuum packaging, and carries out mark according to the kind of simple carbon, sheet carbon, broken carbon and powder carbon.
The method of a kind of tunnel furnace vacuum calcining bamboo charcoal provided by the invention, tunnel furnace vacuum mode is utilized to calcine bamboo charcoal, the ground extensive exploitation of mao bamboon can be abounded with in south, bamboo charcoal can play its unique effect in every field, especially in environmental protection, immeasurable value is played, its method is simple, is convenient to temperature and controls, and producing carbon rate can reach.Tunnel furnace vacuum forging bamboo charcoal, is convenient to temperature and controls, and produces carbon rate and can arrive 30%-40%, and produce carbon rate compared to traditional technology and can improve about 10%, constant product quality, disqualification rate reduces, and utilizes soil within 3-5 years, to be the cycle, can growth and development continuously.
