Description

A kind of device of making biological carbon
Technical field
The present invention relates to a kind of materials processing device, relate in particular to a kind of device of making biological carbon with biomass such as animal waste, agricultural crop straw, rice husk, Pericarppium arachidis hypogaeae, bagasses.
Background technology
Scientists will be take biomass as raw material, and destructive distillation under anaerobic state, the formed a kind of carbonaceous material of pyrolysis are called " biological carbon ".Biological carbon is a kind of form of charcoal, can prolonged preservation in soil and be not broken down into carbonic acid gas.Burying after underground to have hundreds of to more than one thousand years can not disappear.
Any plant or cattle waste can form biological carbon after pyrolysis under oxygen-free environment, carbonization, activation in theory.Make the biomass wide material sources of biological carbon, as animal waste, agricultural crop straw, rice husk, Pericarppium arachidis hypogaeae, bagasse etc.
China's Application Ratio for a long time seriously lacks of proper care, heavy chemical fertilizer, light fertilizer; Diazonium is fertile, light phosphorus, potash fertilizer; Great secondary element, slight secondary element.According to Ministry of Agriculture's statistics, national chemical fertilizer application total amount reached 4,085 ten thousand tons in 1998, with developed country, relatively was equivalent to lose 20% nutrient.Throw the fertilizer efficiency benefit and descend, getting fat is not increased production, and Higher output is not accompanied by a higher income.According to investigations, the 1950's, China's per kilogram chemical fertilizer can be produced 15 kilograms, grain, and be 9 kilograms the seventies, and be 7 kilograms of left and right the nineties.
The unreasonable quality of agricultural product that also causes that applies fertilizer descends, and harm humans is healthy.Show as that melon and fruit is sweetless, food is not fragrant, cotton fibriia shortens, nitrate content harmful in food rises.The nitrate content of several vegetables that the consumption of resident amount is larger (especially leaf vegetables, root vegetables) is severe overweight, and human health is formed potential threat.Because fertilising is unreasonable, cause the aggravation of farm crop physiological disease, fruit profile, mouthfeel are not good, degradation under keeping quality, not only affect China people's quality of life and food safety, more seriously undermined agricultural products in China competitive power in the international market, directly impact foreign exchange earning.
The water body of China's The Great Lakes pool has been subject to pollution in various degree.With regard to the body eutrophication of Taihu Lake, accounted for nitrogen from the nitrogen of Agricultural land loss and entered 23% of lake total amount.
In order to address the above problem, China comes into effect " fertile soil engineering ".The target of this project is:
(1) improve soil reason, voltinism shape; Effectively improve the soil organism, increase chemical fertilizer utilization ratio, strengthen the plant stress-resistance ability;
(2) provide plant-growth required balanced nutrient;
(3) activate soil microorganisms, keep for a long time soil vitality; Improving farmland quality, is the fundamental measure of development grain-production, consolidation and raising overall productivity in agriculture.
(4) make soil fertility improve 1 grade, utilization rate of fertilizer improves 10%, and the grain-production ability improves 10% left and right.
Biological carbon can be present in occurring in nature steadily in the long term, has persistent infertile field fertile soil, promotes the Soil Microorganism breeding, Promoting plant growth, and to carbon dioxide absorption, the function that Carbon Dioxide in Air is reduced.
Biological carbon is rich in micropore, not only can supplement the organic content of soil, can also improve ventilation property and the drainage of soil, holds and stays the required moisture of plant root, effectively preserves moisture and nutriment, increases soil fertility.
Biological carbon, at the special performance that agriculture field has, makes it in implementation of China " fertile soil engineering " process, plays important, irreplaceable effect.
The use of biological carbon, fertile soil, rich peasant.Therefore the demand of biological carbon is increasing, and only from the guestimate of improvement soil angle, China farmland may be 17.6 hundred million tons of left and right to the biological carbon minimal requirement.
Along with Economic development, the supporting capacity of environment reduces, and environmental protection consciousness is constantly strengthened, and impels the emission standard after various sewage disposals to improve constantly.In order to reach new emission standard, activated carbon is used to the various advanced treatment that are difficult to the sewage of processing with biochemical method.Because the explained hereafter cost of traditional production activated carbon is high, cause gac expensive, can't be used on a large scale sewage disposal.A large amount of studies have shown that, the pollutent that biological carbon is removed in sewage has good effect.
With the technology and equipment of traditional manufacturing charcoal carry out on a large scale, industrialization, to make biological carbon at low cost be unpractical.
Although make the biomass material low price of biological carbon, but, the biomass material of making biological carbon as: animal waste, agricultural crop straw, bagasse etc. all contain a large amount of moisture, in manufacturing processed, temperature variation is large, by the 600-850 ℃ of pre-heating stage more than 100 degree to carbonization, activation stage, volume change is large, and last biological carbon product only has the 8-30% of raw material volume.The flue-gas temperature that during pre-heating stage low temperature, equipment is got rid of is very low, but when carbonization, activation stage 600-850 ℃ hot operation, the flue-gas temperature of discharge is spent up to more than 400, and the flue gas thermosteresis is large, and the product temperature after high temperature process is also very high, takes away a large amount of heats.Production Flow Chart is from adding raw material, preheating, carbonization, activation, and the process-cycle is long, and facility investment is large, and production cost is high!
In with biomass, making the process of biological carbon, how can be controllably:
While (1) raw material being carried out carbonization, activation treatment, the high-temperature flue gas of carbonization, activation stage is carried out thermal pretreatment to raw material, with the heat recovery in flue gas;
(2) the high-temperature biological carbon that will produce is transported in special equipment, utilizes the heat in the high-temperature biological charcoal to heat the combustion air of fuel, with the heat recovery in biological carbon;
(3) water vapor that the water vapor that pre-heating stage is produced needs as activation stage, with the heat recovery and utilization in the pre-heating stage water vapor.Can save a large amount of energy.
(4) mixed gas that preheating, carbonization, activation stage is produced carries out purification separation to be processed, and not solidifying combustible gas wherein is transported to combustion chamber, as the fuel of carbonization, activation, available energy is wherein recycled, and lowers production cost.
(5) raw material is carried out preheating, carbonization, activation treatment simultaneously, shorten process period, enhance productivity, reduce costs.
Yet in prior art, to adopt the biomass such as animal waste, agricultural crop straw, bagasse be raw material to this kind, and pollution-free, low-cost, industrialization is made the technology and equipment of biological carbon so far there are no and reports.
