Description
Technical field
The present invention relates to biomass carbon production technical fields, and in particular to a kind of to produce biomass using flue gas in power station boiler
The system and method for charcoal.
Background technique
There are different degrees of heavy metal pollutions for China's soil at present, and especially in some developed areas, agricultural is used
Ground and agricultural product are extremely serious by heavy metal pollution phenomenon.According to statistics, the arable land in China is by the huge sum of money such as cadmium, arsenic, lead, chromium, mercury
Nearly 20,000,000 hectares of arable land for belonging to pollution, accounts for about the 20% of total area under cultivation.Due to heavy metal in the soil poor mobility, be detained
Time is long, cannot be degraded by microorganisms, therefore the difficulty administered and restored is big.Charcoal is a kind of high-carbon solid residue, mainly
By aromatic hydrocarbon and simple substance carbon or there is graphite-like structure, heavy metal biological can not only be reduced by improving the pH value of soil
Validity can also reduce heavy metal-polluted soil mobility by cation adsorption, while charcoal can be by improving and mentioning
High soil fertility reduces murder by poisoning of the heavy metal for plant.
In addition, charcoal can be also used for production charcoal base manure, this is one kind using biomass carbon as matrix, according to different zones
Land characteristics, Different Crop growth characteristic and the principle that applies fertilizers scientifically add the ecology that organic matter or/and inanimate matter are formulated
Environment-friendly type fertilizer.Now in industry it is also known as " carbon-based fertilizer ".
Present charcoal base manure also slowly circulates on the market, and many peasant households also start to focus on supplementing charcoal (carbon) to soil, now
Mainly have in the market: Biologic organic bamboo charcoal fertilizer, bamboo charcoal soil conditioner, bamboo charcoal composite microbiological fertilizer, the bio-bacterial manure of carbon energy, liquid
The products such as state carbon fertilizer；Product category also starts slowly diversification, but final purpose is all, the member of carbon needed for supplementing plant
Element improves the crumb structure of soil, improves the ability of soil water-reataining fertilizer-keeping, improves utilization rate of fertilizer.
Charcoal and soil lock carbon the difference is that, charcoal can steadily lock carbon up to hundreds of
Year.Carbon therein is difficult to decompose again after being mineralized.Importantly, other than the soil improvement function that it has,
The some byproducts generated in production process are even more to have very high economic attractiveness.
Traditional active carbon is using coal as raw material, and raw coal usually contains a certain amount of sieve and silica-sesquioxide etc., content of ashes one
As it is higher, therefore the generation of active carbon from coal pore structure is restricted, and coal is a kind of non-renewable resources.Biomass active
The raw material of charcoal is agriculture and forestry waste, and abundance is cheap, renewable, and it is also real to prepare active carbon using biomass as raw material
The recycling of waste resource is showed.Therefore, the preparation and application of activated carbon from activated sludge have received widespread attention in recent years.
Due to unrealistic using conventional method large-scale industrial production charcoal, researcher starts to turn one's attention to
" pyrolytic " method --- at a high temperature of 500 DEG C to 600 DEG C, organic substance is placed under anaerobic condition, controlledly to it
Carry out pyrolytic.In addition to obtaining charcoal, pyrolytic can also generate the byproducts such as synthesis gas and tar liquid, both are secondary
Product can be used as the fuel of power generation or heating.
The yield of charcoal depends on the speed of pyrolysis process.Quick high-temp resolution accesses 20% biology
Charcoal, 20% synthesis gas and 60% bio oil.And pyrolytic can produce 50% charcoal and a small amount of oil at a slow speed.Britain
Management is thought with the Study on Sustainable Development, since modern high temperature decomposition device can be operated using synthesis gas completely, output
Energy is 3 to 9 times of required energy cost.
In view of the various purposes of charcoal, how low energy consumption, production charcoal becomes key cleanly, current is " high
Temperature is decomposed " method there are energy consumptions it is high, pollution is big the problems such as it is urgently to be resolved.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide a kind of be using flue gas in power station boiler production biomass carbon
