Abstract
The invention discloses biomass compound coal for tobacco flue-curing, which is especially suitable for combustion requirements of bulk curing barn curing equipment. The invention also discloses a preparation method thereof. The invention adopts the following technical scheme to realize the aims: the biomass compound coal for tobacco flue-curing is prepared by the following components by weight percent: 57-95% of coal slime, 0-19% of soft coal with high heat productivity, 0-19% of anthracite, 2-3% of smashed plant straw and 2-2.5% of adhesive, wherein the compound coal also comprises a sulphur fixing agent; and the preparation method has the steps of weighting and mixing the components, and evenly pressing to obtain the product. Based on the scheme, the biomass compound coal for tobacco flue-curing can be obtained, which is especially suitable for combustion requirements of bulk curing barn curing equipment.
Description
Technical field
The invention belongs to biomass coal that a kind of tobacco flue-curing uses and preparation method thereof.
Background technology
Biomass energy is a kind of ideal renewable energy source, its wide material sources, and the content of sulphur is extremely low in the biomass, nonsulfide basically discharging; China some areas have utilized biomass energy to provide the high-quality combustion gas for cooking, heating use for domestic household, but the applied research in tobacco flue-curing is in the junior stage.It is about 1,500 ten thousand mu that the flue-cured tobacco area is planted throughout the year by China, and the coal consumption that is used for baking tobacco leaves every year is more than 4,000,000 tons, and since two thousand four, coal in China price continuous rise causes the flue-cured tobacco cost constantly soaring.Along with bulk curing barn applying in each cigarette district of China, baking labour intensity and energy consumption have greatly improved, but most bulk curing barn roasting plants are had relatively high expectations to coal, and particularly full-automatic roasting plant must be the particle hard coal, and coal price is higher.So the cost that exploration and research match with bulk curing barn is low, the saturating rate height of combustion, pollute less, fuel easy to use just seems very necessary.
Summary of the invention
The object of the present invention is to provide biomass coal that a kind of tobacco flue-curing uses and preparation method thereof, to solve present tobacco flue-curing coal anxiety, price height, the moulded coal that particularly meets bulk curing barn roasting plant combustion requirements, make the saturating rate height of combustion of coal, pollute for a short time, reduce being baked into simultaneously.
The concrete scheme that realizes above-mentioned purpose is: the biomass coal that baking tobacco leaves is used, adopt coal slime and high bituminous coal, hard coal, comminuted plants stalk, sulphur-fixing agent and the tackiness agent of thermal value, the amount of getting mixes to suppress and forms in proportion, by weight percentage: coal slime 57-95%, bituminous coal 0-19%, hard coal 0-19%, straw 2-3%, tackiness agent 2-2.5%.
The preparation method of the biomass coal that baking tobacco leaves is used is as follows:
By aforementioned weight percent, get the weight number of each constituent respectively, bituminous coal, pulverized anthracite are broken to granularity are not more than 1mm, choose dried straw and be crushed to 2-3mm, as the biomass material in the constituent; The tackiness agent Tapioca Starch directly is sprinkled into stirrer by the 20-30kg/ ton raw coal amount of getting.
Earlier bituminous coal, hard coal, comminuted plants stalk and the sulphur-fixing agent handled well are inserted in the stirrer and stir, equably be sprinkled into stirrer in according to formulation weight tackiness agent again, and feeding air pressure is 0.3-0.4MPa, temperature is 145-152 ℃, and flow is 300-400kg/h steam (hourly output is 8-10 tons of meters).It is fully combined with raw material; Restir is to even.
The compound that stirs is imported compression moulding in the briquette shaper, and moisture content is generally 7-10%, and air-dry back moisture content can be transported below 5%, takes out and can use in air-dry 24 hours.
Described biomass material is thought main or used flue-cured tobacco stalk, adhesive therefor fully is to use dried Tapioca Starch.
Can make the biomass coal that baking tobacco leaves of the present invention is used according to such scheme.The special bulk curing barn roasting plant combustion requirements that adapts to.Have: the volatile content of (1) biomass coal is higher relatively, is about 37%, and the combustion fire is easy, and burning-point is the 200-300 degree only, and is more much lower than the burning-point of coal; Be the porous ball, the oxygen supply abundance, combustionvelocity is fast, SO in (2) combustion processes
2Discharging reduces; (3) the moulded coal not slagging scorification of burning, ash content carbon is low; (4) high-pressure molding, the intensity height is convenient to transportation; (5) price is low; (6) but the blending industrial waste, the comprehensive utilization refuse energy.More than 50 kilograms, effects of energy saving and emission reduction is all good with coal in average every stove tobacco leaf saving baking.
Embodiment
Embodiment 1, according to coal slime 57-95%, bituminous coal 0-9%, hard coal 0-19%, straw 2-3%, the weight percent of tackiness agent 2-2.5% is according to the requirement of production, get each constituent of foot respectively, carry out the processing of each constituent before mixing, make it to reach requirement.To stir except that inserting in the stirrer as each composition the Tapioca Starch of tackiness agent, equably be sprinkled into stirrer in according to formulation weight tackiness agent again, and feeding air pressure is 0.3-0.4MPa, temperature is 145-152 ℃, and flow is 300-400kg/h steam (in 8-10 tons of a hourly output).It is fully combined with raw material; Restir is to even.Steam makes it fully combine with raw material.After stirring, compound is imported compression moulding, diameter 4-5cm ellipse or 2-3cm drug sheet in the shaper.The biomass coal of moulding is placed on the better local cool solarization of ventilating and can uses in about 24 hours, can supply traditional flue-curing barn, semi-automatic bulk curing barn and full-automatic bulk curing barn burning and use.The thermal value that requires coal slime is more than 4800 kilocalories, and bituminous coal is more than 5000 kilocalories, and hard coal is more than 5500 kilocalories, and the biomass type calorific value of coal of machine-shaping is enough to satisfy the needs of tobacco flue-curing more than 5000 kilocalories like this.Described coal slime is the mixtures of impurities that comprises flammable coal dust that the coal washing operation produces.
For getting the convenient and combustion efficacy consideration of material, biomass material is thought main or is adopted the flue-cured tobacco crushed stalk to the granularity that requires fully; Tackiness agent is a Tapioca Starch, utilizes the characteristic of its nontoxic and waterproof, strong shock resistance, and not only physical strength is good to make moulded coal after the moulding, and combustion efficacy is good.
The biomass that present technique is used mainly are the depleted plant stems, add tackiness agent, sulphur-fixing agent and tooling cost, hang down about 100 yuan/ton than the raw coal price of equal thermal value; Biomass and raw coal are reasonably combined, can give full play to biomass and raw coal advantage separately, improve the combustioncharacteristics of raw coal effectively, for making full use of of low grade coal source provides possibility.Be easy to realize the accurate control of air distribution in the biomass coal use, and then realization matches with the bulk curing barn Controlling System.Biomass coal is owing to add biomass, and the size of catching fire more easy to control in combustion processes is lighted a fire soon, and the intensification rate of temperature fall is all very fast, can satisfy the demand of method for flue-curing tobacco leaves better.
