Energy shortage and ecocrisis are the focuses that society is paid close attention to, and are also the bottlenecks of development of modern society economy.The fossil energy epoch of the earth move towards termination gradually, and the fossil energy situation of China is more very severe.Energy supply and demand is in short supply will the development of restriction China economy and society, finds new, that renewable energy source the has become China task of top priority.Contrast fossil energy, biomass energy becomes the new force of energy industry gradually because of advantages such as it is renewable, aboundresources, eco-friendlies, play an important role in society Economic development.In world's energy consumption, biomass energy consumption accounts for about 14% of energy total amount, particularly some under-developed areas, and biomass energy consumption accounts for more than 60% of energy total amount.In " planning of renewable energy source Long-and Medium-term Development " that National Development and Reform Committee formulates, regulation, strives reaching 5,000 ten thousand tons to the year two thousand twenty China biomass solid formed fuel year utilization.For promoting forestry biomass energy development, the State Administration of Forestry has formulated " forestry biomass energy development program (2011-2020) ", propose and will make full use of existing scrub growth, firewood forests, forestry residue, woody oil forest and starch-containing class forest resourceies and to develop forestry biomass energy, and utilize waste mountain waste suitable for afforestation and marginal land development energy forest.
At present, China does not also have product and the production technology of bamboo wood roasting charcoal, lags behind the developed countries such as European Union, the U.S., Canada.In 2012, the roasting charcoal research team (SECTOR team) that European Union is made up of 21 countries, property of raw material and pre-treatment, logistics, sinter process and equipment, compressing and forming process and equipment, product standard, feasibility and Analysis On Sustainability, burning process and equipment etc. are studied, and set up tackling key problem group, integrated multi-party resource and achievement in research, strive suitability for industrialized production and application that within 4 years, inherent Europe realizes roasting charcoal.Canada and present Ye Youji company of the U.S. are engaged in the research and development of this respect.The pilot plant that nearly more than 30 scales in the current whole world do not wait, they adopt different roasting technologies and equipment, different biomass materials, produce " roasting charcoal " fuel that performance is similar to traditional coal.
Summary of the invention
The object of the present invention is to provide a kind of power self-support type bamboo biological matter roasting charcoal preparation method.
To achieve these goals, the technical solution used in the present invention is: a kind of power self-support type bamboo biological matter roasting charcoal preparation method, is characterized in that: method steps is as follows,
A. selection, is processed into thick bamboo tube, bamboo chip, the bamboo particle of certain size by bamboo wood or bamboo waste;
B. dry, above-mentioned bamboo wood material is carried out drying treatment, removes moisture, make water ratio drop to less than 12%;
C. low-temperature bake, under 200 DEG C of-300 DEG C of low temperature, under the condition of starvation, carry out carbonization at low temperature process to dried bamboo wood material, carbonization time is 1-5 hour, forms the liquid of bamboo biological matter roasting charcoal fuel, biogas and minute quantity;
D. the biogas will produced in carbonization process, by separation system, after purification, separation, for the thermal source in bamboo biological matter roasting charcoal preparation process;
E. cool, the bamboo biological matter roasting charcoal after carbonizing treatment is cooled to chambers temp;
F. pack.
As preferably, in step c, carbonization temperature during roasting is 250 DEG C-300 DEG C, and anoxybiotic carbonization time is 2 hours, now carbonization best results;
As preferably, in step c, the biogas that roasting produces is hydrogen, carbon monoxide and methane etc., by collecting, purification, be separated after for the energy in carbonizing treatment process.
As preferably, in step c, the minute quantity liquid that roasting produces is terpenes, phenol, Weibull, can collect and refining further.
Compared with prior art, the invention has the advantages that:
(1) environmental friendliness: the combustionproperty of low-temperature bake bamboo biological charcoal can compare favourably with traditional coal, the two mixed firing significantly can reduce greenhouse toxic gas discharge.
(2) good manufacturability: adopt carbonization at low temperature technique, save energy consumption; The inflammable gas produced in carbonization process, can Collection utilization further, for the thermal source of carbonization process, realizes heat energy " zero " demand.
(3) excellent performance: compared with carbonization treatment technique (450-600 DEG C) domestic at present, after carbonization at low temperature process, the physical mechanics property loss of energy of material is few, and bamboo biological matter roasting charcoal performance meets current United States and European product standard code or service requirements.
Embodiment
Below by embodiment, the invention will be further described.
Embodiment 1: thunder bamboo is processed into the thick bamboo tube that length is 20 centimetres is anoxybiotic carbonization 2 hours under the condition of 300 DEG C in carbonization temperature.After carbonization, the combustion heat value of bamboo wood is increased to 27KJ/g from 18KJ/g, and volatile content drops to 30% from 80%.
Embodiment 2: mao bamboon is processed into bamboo chip is anoxybiotic carbonization 2 hours under the condition of 250 DEG C in carbonization temperature.After carbonization, the combustion heat value of bamboo wood is increased to 23KJ/g from 18KJ/g, and volatile content drops to 52% from 80%.
Embodiment 3: mao bamboon is processed well-thought-out plan particle is anoxybiotic carbonization 2 hours under the condition of 200 DEG C in carbonization temperature.After carbonization, the combustion heat value of bamboo wood is increased to 20KJ/g from 18KJ/g, and volatile content drops to 65% from 80%.
