Description
Technical field
The present invention relates to a kind of drying equipment, belong to agricultural mechanical field, especially relate to a kind of biogas infra-red radiation cylinder crop dryer.
Background technology
China is grain-production maximum in the world and consumer nation, 2,011 5.7 hundred million tons, gross annual output grains.In recent years, perfect due to agriculture system, agrotechnical popularization, the total grain output steady-state growth year by year of China, but China is vast in territory, spectacular, in grain harvest season, often run into rainy weather, make cereal can not be dry in time and germinate and go mouldy, bring about great losses.According to statistics, the loss after China's grain harvest in the processes such as threshing, airing, storage, transport up to 15%, considerably beyond FAO (Food and Agriculture Organization of the United Nation) regulation 5% standard.In these losses, annual because having a humid climate, wet paddy have little time to dry or do not reach safe moisture cause go mouldy, the grain of the loss such as germination up to 5,000,000,000 kilograms, serious year's harvest loss even also wants many up to 10%, economic loss up to 30,000,000,000 yuan ~ 60,000,000,000 yuan.The Northeast's wheat harvest period on average every 3 years be just rainy season one year, need grain drying machinery especially, in the long-term situation in Guangdong Province, grain loss about 200,000,000 ~ 300,000,000 kilograms, reaches 500,000,000 kilograms time serious.
China's foodstuff preservation limits by management system, and there is grain depot and concentrate grain storage and peasant household place of production dispersion grain storage two kinds of modes.First kind of way is national grain depot concentric acquisition tide grain, and the basic large-sized drying machines that adopts carries out concentrating drying, then stores; After the dispersion of second way peasant household carries out drying voluntarily, pay the commodity food of safe moisture to grain depot and store.Economize at grain main product, because grain depot drying facility is complete, grain loss is less (about 3%) also, and the equipment such as the drying machine of peasant household's place of production dispersion grain storage famine necessity, cause the loss of 5% ~ 15%.At present, domestic drying machinery recoverable amount rises fast with the amplification of average annual about 50%, but annual mechanical drying cereal only accounts for about 1% of national total grain yield, and World Developed Countries machinery grain-drying can reach about 95% of total output, the grain-drying machinery development of visible China can not be adapted to cereal production development needs far away.
Condition of Grain-Drying Technology has heated-air drying, drying generator, low-temperature vacuum drying, heat pump drying, solar energy drying, microwave drying, infrared radiation drying, combined drying method etc. usually.
Hot-air seasoning is the grain drying method be most widely used at present, accounts for 90% of China's grain drying operation.It adopts the hot-air with uniform temperature to want dry material surperficial to reduce the moisture of material through institute, thus reach the object of drying.Heat transfer type based on convection heat transfer' heat-transfer by convection drying mode, apply more be concurrent drying, along the drying mode such as mixed flow drying and fluidized bed drying.Heated-air drying is simple to operate, with low cost, under comparatively high dry temperature, usefulness is higher, but because of dry treatment temperature high, cause the quick-fried waist of part grain grain (percent cracked rice more than 7%), color, smell and taste and nutritional labeling are destroyed, product specification reduces, and be not suitable for the drying of high-quality grain, and Thermal Efficiency of Hot Air Drying is greatly affected under lower working temperature environment, energy utilization rate is lower, and cost is higher.Comparatively speaking, there is many shortcomings in this dry technology, and energy as comparatively slow, that consume in rate of drying is high, but easily-controlled operation.
Drying generator is using natural air or adds hot-air as drying medium, carries out forced ventilation process to high moisture grain in storehouse.Can put in storage after being characterized in grain harvest, reduce the link such as airing, drying outside storehouse, grain quality can be kept to greatest extent.The disposable process quantity of the method is large, and invest less, drying cost is lower, loses little, is applicable in enormous quantities, the dry process of scale.Shortcoming is that the aeration-drying of large granary deep layer grain is difficult, uneven drying phenomenon is general, is not suitable for dry with batch cereal etc. that moisture difference is larger.At present, the mobile three-dimensional drying generator technology being applicable to China's chamber storehouse grain storage form drops into practical application in some areas, and this complete set of equipments adopts combination, mobile easy for installation, can grain heap be replaced mobile by equipment moving, equipment be once invested, and can repeatedly use in many storehouses.
Low-temperature vacuum drying method is the principle changed with environmental pressure size according to the height of grain moisture content explosive evaporation temperature, utilize steam jet vacuum technique to form the space with certain vacuum degree, under vacuum and low temperature state, the continuous grain high to moisture content dehydrates.During operation, grain internal and external temperature gradient is little, by reverse osmosis effect, the moisture in grain is moved alone, and overcome solute and to scatter and disappear phenomenon, original color after can ensureing grain heat-drying, nutritional labeling, quality are substantially constant, is convenient to storage, transport and sells.The method has that treating capacity is large, precipitation range is high, flexible operation, the advantage such as easy to use.Its weak point is that equipment one-time investment is large, current turriform continuous vacuum drying equipment in dryness storehouse without guider, dried material cannot horizontal cross-flow in storehouse, and warehouse structural thermal insulation, sealing requirements are high, and dried grain quality stability is difficult to guarantee.In addition, because vacuum drying vaporization boiling point is low, baking temperature is low, oxygen content only has 5% of constant pressure and dry, therefore can be used for the drying of foodstuff seed.
Heat pump techniques absorbs heat from low-temperature heat source, and making it release the technology of available energy at relatively high temperatures, is the obvious and practicable novel dried technology of a kind of energy-saving effect.Utilization heats working medium and evaporates in evaporator for decompression, waste heat is recycled from dried tail gas, and gaseous working medium enters condenser again after compressor compression, condensation discharges latent heat preheat fresh air at relatively high temperatures, make drying medium obtain the temperature also higher than EGT, reach the object of dried material.Abroad, heat pump drying technology has been widely used in the process of the materials such as cereal, fruits and vegetables, aquatic products.The research of China's heat pump drying technology is started in the eighties in 20th century, does not also obtain actual property break through in grain scale application aspect.
Solar energy drying is the heat energy utilizing solar radiation, by the dry technology of the moisture evaporation removing in wet stock.Utilize solar energy to carry out grain drying and generally have 2 kinds of modes, one is with air or water for medium, and to utilize solar water heater can by water temp. heating to 98 DEG C in sunlit situation having, recycling hot aqueous medium carrys out dried material; Two is set up passive type solar energy greenhouse, and dried material is placed in greenhouse inner drying.The maximum deficiency of solar energy drying is that one-time investment is comparatively large, and large by the impact of weather conditions, often needs to be combined with other drying means.
Microwave refers to that frequency is the electromagnetic wave of 300MHz ~ 3000GHz, and the electromagnetic wave of wavelength between 0.1mm ~ 1m, usually also referred to as " uhf electromagnetic wave ".The principle of method for microwave drying is the motion relying on frequency electromagnetic waves to cause water isopolarity molecule in dried material, makes the water isopolarity molecule in material do synchronous rotary and swing by microwave frequency.The result of water isopolarity molecule High Rotation Speed, makes the instantaneous generation frictional heat of internal batch, causes internal batch and surface to be heated up simultaneously, make a large amount of hydrones evaporate effusion from material, thus reaches dry object.The advantages such as microwave drying has strong, the selective heating of penetration capacity, thermal inertia is little, rate of drying is fast, the time is short, meet environmental requirement, and are easy to realize automatically controlling.Microwave current dried grain technology is at home and abroad still located under study for action.
Infrared radiation seasoning be utilize wavelength between 760nm ~ 1mm, between visible ray and microwave electromagnetic wave irradiation to material time, a part is absorbed, a part is reflected, that part energy absorbed is converted into the warm-up movement of molecule, object temperature is raised, reaches the object of heat drying.Infrared drying is the theme of Recent study, it not only have transmit that the thermal efficiency is high, the heat time is short, object is heated evenly, working environment is clean, equipment noise is low, economize energy, device are compact, be convenient to automatic control, easily by some objects the advantage such as to absorb, and can more effectively avoid or reduce quick-fried waist phenomenon.Therefore, just current grain dry technology, after each side factors such as its drying cost of consideration, drying time and drying device, can affirm that infra-red drying technology is best suited for, has most the effective ways of development potentiality.
The research of combined drying method grew up in recent years.Combined drying is exactly the dry feature according to material, two or more dry technology integrated, realize energy-conservation, guarantee the quality and highly effective drying effect.China researcher has carried out exploration and the research of multiple combined drying technology, as infrared combined drying, microwave combining drying, radio frequency-fluidized bed drying associating, solar energy-heat pump drying are combined.
In sum, current drying plant is general heavy tall and big, and what mostly take is hot blast, does fuel carry out heating, drying with coal, and is mostly large-scale plant.Therefore cost is higher, wastes national fuel source greatly, supposes to dry every day 150 ton-grain foods and will consume 4 ~ 5 tons of coals, the fuel cost about 4 ~ 5,000 yuan of user every day.In new rural village evolution now, there is a large amount of new village cooperative societies pattern, contracted nearly hundred mu of groups to thousands of mu of farmlands and continue to bring out, need the crop dryer of this type of scale applicable badly, and expected that this drier can also other agricultural byproducts dry.
On the other hand, the development of China's production and use of marsh gas enters the new stage of great development, fast development.By the end of the end of the year 2011, national household biogas will reach 3,996 ten thousand families, and account for 23% of the total amount in rural area, benefited population reaches people more than 1.5 hundred million.Expect 2015, Country Household Using Marsh Gas user reaches 5000 ~ fifty-five million family.In rural area, biogas belongs to renewable and clean energy resource, is also the important means of Countryside Environment Rectification.But it is estimated, be in the good biogas engineering that runs at present less than 20%, nearly 1/3 running is bad, and all the other are then in shut down condition.Basic reason is that Gas application is backward in technique, market power shortage, and wherein biogas combustion technology is maximum bottleneck.Because biogas contains the methane of 55% and the carbon dioxide of 45%, methane is the slower hydrocarbon of burning velocity, in biogas, the existence of inert gas carbon dioxide reduce further burning velocity, make burning completely and the lifting of burner rating run into restriction (such as in the market the power of Marsh gas water heater all lower than 8 liters/min); In addition biogas production because of the usual pressure oscillation of state of arts frequent, cause combustion flame unstable, discharge performance is poor, and the thermal efficiency is low.Fully-premixed technology is mixed completely before entering combustion chamber burner with air combustion gas, through premix chamber, gas molecule is fully stirred loose mixing, make mixing more complete, thus making burning velocity no longer be limited to the physical conditions such as gas diffusion velocity, burning is more completely, speed is faster, efficiency is higher.Because the air added is with the quantity premix close to combustion stoichiometry ratio, so burning required air quantity is less than conventional method, combustion product gases amount is reduced, decrease flue gas heat radiation, improve efficiency of combustion.Full premix technology effective improves the mixed effect of combustion gas and air, pressure, flow velocity is reached an agreement through premix chamber simultaneously, avoids biogas inlet pressure to fluctuate and the situation generation not etc. of burner outlet speed.Through fire hole ejection after-combustion, owing to completing precise proportions mixing, make combustion process complete, burning velocity is fast, and flame temperature is high, and discharge performance is good.
Infra-red drying application is industrially very general, because it has the application of numerous advantages on grain dry also more and more to come into one's own.In the dry run of infra-red radiation, because infrared ray has certain penetrability, thermal accumlation is formed at internal batch, adding the continuous evaporation endothermic of dried material surface moisture makes material surface temperature reduce, cause internal batch higher than external temperature, the thermal diffusion process of material is undertaken by interior.Simultaneously, the moisture caused due to the gradation of moisture of internal batch moves, always moved to the outside that moisture is less by the inside that moisture is more, so the wet diffusion of internal batch moisture is consistent with thermal diffusion direction, namely this diffusion process that will speed up moisture also accelerates dry process.
