Description
Technical field
The invention belongs to field of renewable energy technology, particularly a kind of self-employed tree cultivator's waste self-heated pyrolysis device.
Background technology
Since 20 century 70s outburst oil crisises, the former oil supplying in the world is more and more nervous, and the crude oil demand of world every day in 2011 is about 87.3 MMbbl, and according to estimates, to the year two thousand thirty, the crude oil demand of world every day will reach 117.6 MMbbl.The demand in additional 30.3 MMbbl/sky is about equivalent to 3 Saudi crude oil daily outputs.From the situation of China, in recent years along with the fast development of national economy, China to the demand sustainable growth of petroleum resources, 2011, China's oil external dependence degree reaches 56.5%, and Oil Safety will inevitably become an important component part of national security." 12 " period, China is still in industrialization and urbanization accelerated development stage, and along with the further expansion of economic scale, energy demand also can continue very fast increase, estimates that the Energy situation faced during " 12 " is still severe.The energy has become in quite long at present and in the future period of China, the outstanding bottleneck of restriction economy and social development.
The world consumes a large amount of fossil oil (coal, oil, Sweet natural gas) every year on the one hand, and a large amount of fossil oil that uses result in Heavy environmental pollution and other ecological problems on the other hand.The coal-fired carbonic acid gas about 1,000,000,000 tons with using the fossil oils such as oil to produce as annual in China.China is just enough to after being often only coal fire discharged sulfur dioxide liquefaction fill up more than ten West Lakes, produces about 300,000,000 tons of flue dust simultaneously.Great amount of carbon dioxide, sulfurous gas isothermal chamber gas and other solid particulate matters that use oil, coal discharge at interior fossil oil create serious topsoil and noxious waste pollution, cause serious Greenhouse effect, define heavy rain, arid and unusual hot weather.
In order to alleviate the pressure of crude oil supply and demand, safeguarding energy security, preserving the ecological environment, realize the Sustainable development of human society, countries in the world are all stepping up to develop biomass energy.But the distribution height of biomass resource disperses, yield per unit lower (1.6 tons/mu), energy per volume density is lower, collection in enormous quantities, transport and storage biomass resource have huge obstacle and difficulty, determine the technological line that bio-energy industry can not walk the concentrated scale operation/process of similar petrochemical complex and Coal Chemical Industry, and the technological line of " distributed production/pre-treatment-pooled applications/refining " should be walked.
Biomass (as various crop stalk, fallen leaves and branch) can be converted into bio oil (productive rate 50wt%-70wt%) by fast pyrolysis technology.Bio oil is a kind of brown liquid, and calorific value is about 15MJ/kg, proportion about 1.2.Biomass are converted into after bio oil through fast pyrolysis processes, by original loose solid state transformed be liquid, volume energy density adds 3-5 doubly, is more applicable to transport (tank wagon, pipeline), stores (oil tank) and further refining processing.So, fast pyrolysis technology is very applicable to " distributed production/pre-treatment-pooled applications/refining " pattern, namely be bio oil by fast pyrolysis technology (treatment scale: 5 tons/t days-500 tons/t days) by lignocellulosic biomass conversion in different areas, then the bio oil that each department are produced be transported to central factory and concentrate and use (combustion heat supplying/generating) or concentrate refining to be senior liquid fuel (as methyl alcohol, dme and vapour, diesel oil) further.The eighties in last century is early stage, and the research work of pyrolytic technique has been carried out in North America first.After this, countries in the world successively establish multiple pyrolysis installation, try hard to realize the industrialization of pyrolytic technique.These pyrolysis installations and related process route can be divided three classes:
As the fluidized bed pyrolysis device that the Dynamotive company of North America, Ensyn company, China Science & Technology University and University Of Science and Technology Of Shandong (China) are representative, the decline tubular type pyrolytic reaction device that the rotating cone pyrolysis installation of Dutch BTG company development and Shandong Technology Univ (China) develop is representative.Rotating cone pyrolysis installation is made up of burner, rotating cone reactor, powdered carbon tripping device and bio oil condensing works.Sand in burner, in burner combustion, is heated to high temperature by powdered carbon, and high temperature sand is conveyed into rotating cone reactor and contacts with agriculture and forestry organic waste material, agriculture and forestry organic waste material generation pyrolysis, generates bio oil steam, powdered carbon and non-condensable gases.Powdered carbon and sand are separated by powdered carbon tripping device from gas, and send into burner, powdered carbon burns in burner, heating sand.After bio oil steam enters condensing works condensation, obtain liquid bio oil.Decline tubular type pyrolytic reaction device and the rotating cone pyrolysis installation of Shandong Technology Univ's exploitation are similar in principle, decline tubular type pyrolytic reaction device is made up of burner, decline tubular type pyrolysis reactor, powdered carbon tripping device and bio oil condensing works, burn in burner agriculture and forestry organic waste material, the heat heating particle diameter produced is about 3mm ~ 5mm Ceramic Balls, the Ceramic Balls of high temperature is admitted to decline tubular type pyrolysis reactor and contacts with agriculture and forestry organic waste material, agriculture and forestry organic waste material generation pyrolysis, generates bio oil steam, powdered carbon and non-condensable gases.After bio oil steam enters condensing works condensation, obtain liquid bio oil.
3rd class pyrolysis installation is with the vacuum moving bed pyrolysis device of Canadian Laval company for representative, and this device is made up of burner, vacuum moving-bed, powdered carbon tripping device and bio oil condensing works.Powdered carbon obtains heat by NaNO in burner combustion
3, KNO
3and NaNO
2mixture heating and melting, the high-temp liquid salt of thawing is introduced into vacuum moving-bed, and high-temp liquid salt and agriculture and forestry organic waste material are at vacuum moving-bed indirect heat exchange, and agriculture and forestry organic waste material generation pyrolysis, generates bio oil steam, powdered carbon and non-condensable gases.Bio oil steam and non-condensable gases are extracted out by vacuum pump, and bio oil steam is admitted to condenser condenses, and condensable gases is not admitted to burner combustion, for heating and melting salt.Because agriculture and forestry organic waste material pyrolysis obtains not condensable gases burning quantity of heat production deficiency, therefore this device needs auxiliary electric heater unit.
The heat that above-mentioned three class pyrolysis installations all adopt independent burner to produce pyrolytic reaction to need, the mode of the salts solution of then heat is husky with high-temperature flue gas, heat, thermal Ceramics ball or melting introduces pyrolysis reactor.Its shortcoming is that support equipment is complicated, operational difficulty.Need to select suitable blower fan, pipeline, material-returning device and anti-channeling device of air etc. because powdered carbon is recycled to burner from powdered carbon tripping device or not condensable gases is recycled to burner; Heat is introduced pyrolysis reactor and also need suitable blower fan, pipeline or interchanger etc.Also need carefully to mate various processing parameter simultaneously, as various parameters such as air quantity, temperature, pressure and vacuum tightnesss, careless slightly, just may cause the paralysis of whole pyrolysis installation.Powdered carbon accounts for 15% ~ 30% in whole pyrolysis product, powdered carbon in pyrolysis gas (bio oil steam+not condensable gases) is dense, as powdered carbon not effectively being separated, a lot of powdered carbon will be mixed in liquid bio oil, produces huge obstruction to the utilization of bio oil.In addition, powdered carbon density is low, out-of-shape, easily piles up at powdered carbon collection device, builds bridge, produce blocking, thus affect the continuous operation of whole pyrolysis installation.Pyrolysis installation generally adopts cyclonic separator to be separated powdered carbon, but in the past the cyclonic separator that adopts of pyrolysis installation at effective separation of high-concentration powdered carbon with to prevent powdered carbon from piling up effect in bridge formation bad.The cyclonic separator of patent of the present invention adopts scroll casing type entry mode, for this entrance structure, reduce because gas enters the open area after spiral case, gas is accelerated gradually before entering main separated space, at volute inlet section first separating most powdered carbon particle.In addition, the speed of rotation of the interior whirlpool vortex core of gas is corresponding to be increased, and also improves separation efficiency.Scroll casing type entrance structure is extremely applicable to the pyrolysis operating mode processing large discharge, high powdered carbon concentration.Because the first step cyclonic separator in pyrolysis installation the most easily occurs piling up arch formation, produce blocking.
Bio oil condensing works in the past generally uses packing tower and shell and tube heat exchanger.Packing tower adopts direct condensing mode, has good condensation effect.Because bio oil viscosity is comparatively large, also can be mingled with some charcoal particles, therefore packing tower is when condensation bio oil, and liquid bio oil is mingled with powdered carbon, can be deposited on filler, causes packing tower pressure drop ratio to block more greatly, easily.Tubular heat exchange adopts indirect condensing mode, not easily blocks, but cold effect is not as packing tower, and maintenance is difficulty comparatively.
