Description
Technical field
The present invention relates to the pyrolysis installation and the pyrolytic process of biomass.
Background technology
At present, countries in the world are developed country especially, for the Sustainable development that realizes national economy provides basic guarantee, all is being devoted to develop efficient, free of contamination biomass energy utilization technologies, to protect the fossil energy resource of this country.Biomass pyrolytic is meant that biomass are not having oxygenant (air, oxygen, water vapour etc.) to exist or only providing under the condition of limited oxygen; Be heated to and exceed 500 ℃, biomass macromolecular substance (xylogen, Mierocrystalline cellulose and semicellulose) is resolved into the thermochemistry transformation technology method of fuel material (solid-state charcoal, combustible gas, bio oil) through thermal chemical reaction than small molecules.The fuel energy transformation efficiency of biomass pyrolytic can reach 95.5%, to greatest extent biomass energy is converted into energy product, make the best use of everything, and pyrolysis also is burning and gasifies the requisite starting stage
From the angle of chemical reaction it is analyzed, complicated thermal chemical reaction has taken place in biomass in pyrolytic process, comprises reactions such as molecular scission, isomerizing and small molecules polymerization.The staple of timber, forestry waste and agricultural waste material etc. is Mierocrystalline cellulose, semicellulose and xylogen.Thermogravimetric analysis is the result show, Mierocrystalline cellulose begins pyrolysis in the time of 52 ℃, and along with the rising of temperature, pyrolytic reaction speeds up, and during to 350～370 ℃, is decomposed into low molecular product.According to the temperature variation of pyrolytic process and the situation that generates product etc., can be divided into drying stage, stage, solid catabolic phase and calcination stage are separated in preheating.Drying stage (temperature is 120～150 ℃), the moisture in the biomass evaporates, and the chemical constitution of material is almost constant.(temperature is 150～275 ℃) separated the stage in preheating, and the thermal response of material is apparent in view, and chemical constitution begins to change, and unstable constituents in the biomass such as semicellulose resolve into materials such as carbonic acid gas, carbon monoxide and little acetic acid.Above-mentioned two stages are the thermo-negative reaction stage.Solid catabolic phase (temperature is 275～475 ℃), the pyrolytic main phase, physics, the chemical reaction of various complicacies taken place in material, produces a large amount of degradation productions.Contain acetic acid, wood tar oil and methyl alcohol (separating out during cooling) in the product liquid that generates; CO2, CO, CH4, H2 etc. are arranged in the gaseous product, and combustiblecomponents content increases.This stage will be emitted a large amount of heat.Calcination stage (temperature is 450～500 ℃), biomass rely on the outside heat of supplying with to carry out the burning of charcoal, and the volatile matter in the charcoal is reduced, and fixed carbon content increases, and is exothermic phase.In fact, the boundary of above-mentioned four-stage is difficult to clearly divide, and the reaction process in each stage intersection is each other carried out.
From heating rate and the angle of accomplishing the used time of reaction to biomass, biomass pyrolytic technology can be divided into two types basically: a kind of is pyrolysis at a slow speed, and a kind of is fast pyrogenation.In fast pyrogenation, when accomplish the reaction times very short (＜0.5s) time, be called the flash pyrolysis again.According to process conditions, biomass pyrolytic technology can be divided at a slow speed again, three kinds of quick and reactive pyrolysis.In slow pyrolysis process, can be divided into charing and conventional pyrolysis again.
Pyrolysis at a slow speed (claiming distillation process, traditional pyrolysis again) technology has history in several thousand; Be a kind of be the carbonization process of purpose to generate charcoal; The Heating temperature of low-temperature pyrolysis is 500～580 ℃, and the medium temperature carbonization temperature is 660～750 ℃, and the temperature of high temperature carbonization is 900～1100 ℃.Timber is placed in the kiln, under the situation of secluding air, heats, can obtain accounting for the char yield of raw materials quality 30%～35%.
Fast pyrogenation is that the levigated biomass material is placed in the rapid pyrolysis apparatus; Strict control heating rate (generally be roughly 10～200 ℃/s) and temperature of reaction (being controlled at about 500 ℃); Biomass material is under the anoxybiotic situation; Be rapidly heated to comparatively high temps, thereby cause macromolecular decomposition, produced micro-molecular gas and condensability volatile matter and a small amount of coke produced.The condensability volatile matter is cooled to flowable liquid fast, becomes bio oil or tar, and its ratio generally can reach 40%～60% of raw materials quality.
Compare with pyrolysis at a slow speed, the heat transfer reaction process of fast pyrogenation occurred in the extremely short time, and the intensive heat effect directly produces pyrolysis product, and quenching rapidly is chilled in 0.5s below 350 ℃ usually again, has increased liquid product (oil) to greatest extent.
Generally, influence the pyrolytic principal element and comprise chemistry and physics two broad aspect.Chemical factor comprises the primary first-order equation and the secondary reaction of a series of complicacies; Physical factor mainly is the physical property of heat transfer, mass transfer and raw material in the reaction process etc.Concrete operational condition shows as: temperature, material characteristic, catalyzer, residence time, pressure and temperature rise rate.
In biomass pyrolysis process, temperature is a very significant effects factor, and it all has very big influence to pyrolysis product distribution, component, productive rate and pyrolysis gas calorific value.What of gas in the biomass pyrolytic final product, oil, each accounting example of charcoal have very big-difference with the height of temperature of reaction and the speed of rate of heating.Generally speaking, low temperature, long-term pyrolysis at a slow speed of being detained are mainly used in the output that increases charcoal to greatest extent, and its mass yield and energy productive rate reach 30% and 50% (massfraction) respectively.Temperature adopts medium speed of reaction during less than 600 ℃ conventional pyrolysis, and the productive rate of bio oil, non-condensable gas and charcoal is equal basically; The flash pyrolysis temperature mainly is used for increasing the output of bio oil in 500～650 ℃ of scopes, the bio oil productive rate can reach 80% (massfraction); Same flash pyrolysis if temperature is higher than 700 ℃, under residence time, is mainly used in the process gas product in very high speed of reaction and the gas phase of extremely lacking, and its productive rate can reach 80% (massfraction).When temperature rise rate was exceedingly fast, semicellulose and Mierocrystalline cellulose generated charcoal hardly.
There is the branch of solid phase residence time and gas residence time residence time in the biomass pyrolytic reaction.The solid phase residence time is short more, and the shared ratio of pyrolytic solid product is just more little, and total product amount is big more, and pyrolysis is complete more.Under the condition of given temperature and temperature rise rate, the solid phase residence time is short more, and the solid product in the converted product of reaction is just few more, and the amount of gas-phase product is just big more.Gas phase time residence time does not generally influence a scission reaction process of biomass, and only has influence on the process of the second pyrolysis reaction of the bio oil generation in the liquid product.Center in the gas phase of biological particles when a product in the biomass pyrolysis product gets into, further cracking reaction will take place in bio oil, in red-hot reactor drum; Gas residence time is long more; It is just serious more that the second pyrolysis of bio oil takes place, and the second pyrolysis reaction increases, and emits H2, CH4, CO etc.; Cause liquid product to reduce rapidly, gaseous product increases.So, for obtaining maximum bio oil output, should shorten gas phase residence time, make the volatility product reactor drum that speeds away, reduce the time of secondarily cracking tar.
Conventional method for pyrolysis is that biomass material is placed in the existing pyrolysis installation in the prior art, for example fluidized bed pyrolysis.This pyrolysis is normally in (0.1～1 ℃/s) under the condition, through the pyrolysis of several hrs, obtain accounting for 20%～25% biomass charcoal of raw materials quality and 30%～40% bio oil of moderate temperature and medium speed of reaction being lower than 600 ℃.In fluidized-bed reactor; Its solid particulate was fluidized state after biological particles was heated to suitable temp under the drive of nitrogen; Biomass are accomplished pyrolytic process at 1-3 in the residence time of second, are got into cyclonic separator by various organism of cracked and coke then, and coke separates the back and collects reuse; Gas then gets into condensing surface, promptly obtains the bio oil of complicated component after the condensation.Because the residence time of biological particles in fluidized-bed reactor can't accurately be controlled in the pyrolytic process; Pyrolysis temperature also is difficult to control; Therefore the pyrolysis product complicated component that obtains can't realize that pyrolysis product is the controlled of bio oil composition, is not easy refining and extracts chemical.That is to say that bio oil composition and concentration that existing pyrolytic technique obtains are at random.Therefore its bio oil that obtains can only be as low-grade fuel, and added value is lower, and this has limited the popularization of pyrolytic technique.
Summary of the invention
The objective of the invention is to, a kind of spiral pyrolysis installation and the pyrolytic process thereof that can accurately control biological particles pyrolysis time and pyrolysis temperature is provided, thereby effectively controls bio oil composition and concentration, make the biomass pyrolytic technology can further obtain promoting.

In the said apparatus, the outer heating system that said pyrolysis reactor has is an electric heating panel whole or isolating power-adjustable, and every electric heating panel is provided with thermometric thermopair.
In the said apparatus, said screw-blade as spiral propeller, garden shape cylinder inboard wall and rotation axis surface constitute by corrosion resistant material, to prevent to influence because of corrosion phenomenon the quality of bio oil.
Utilize spiral pyrolysis installation of the present invention that biomass are carried out the pyrolytic technological process, comprise the at first outer heating of startup system, make the reaction zone temperature in the spiral pyrolysis reactor be stabilized in 500-550 ℃; Again the biological particles raw material is delivered into spiral pyrolysis reactor through inlet pipe; It is characterized in that, start variable-frequency motor simultaneously, and according to the residence time t of biomass in spiral pyrolysis reactor that sets; And the axial length L of spiral pushing device and pitch l, use formula
Confirm the rotation speed n of variable-frequency motor, velocity of rotation is in 100-400 rev/min of scope usually; Start the pyrolysis product gathering system then, can obtain liquid bio oil and other pyrolysis product.Said biological particles raw material is pulverized biological particles, and its particle diameter is the 20-200 order.
In actually operating, can suitably adjust the variable-frequency motor rotating speed then according to the attributional analysis of the bio oil that obtains, promptly adjust the residence time of biomass in helical reactors, to obtain suitable bio oil quality and yield.

Spiral pyrolysis installation of the present invention carries out the pyrolytic technological process to biomass, compared with prior art, two major advantages is arranged:
(1) can control the residence time of biomass in the reactor drum device accurately:
The residence time of biomass in fluidized-bed reactor is general relevant with the useful volume of inlet amount and fluidized-bed reactor; It is a mean residence time; Because the mixture kinestate in the fluidized-bed is complicated; Often have short circuit, back-mixing and dead angle phenomenon, and because biological particles continuous weightlessness etc. in pyrolytic process, individual residence time of biomass is widely different.Therefore mean residence time can't accurately reflect the individual residence time.This spiral pyrolysis reactor is then fully different, as long as pitch reasonable in design, avoids material to skid and regurgitates phenomenon, then mean residence time just of the individual residence time of biomass.
Theoretically, biological particles residence time in reactor drum is different, the asynchronism(-nization) that promptly reacts, and the composition of its pyrolyze product promptly can be had any different, and also is that bio oil composition and concentration can change.Spiral pyrolysis installation of the present invention; Because the velocity of rotation of rotation axis can be regulated by variable-frequency motor; Make the gait of march of biological particles, promptly the residence time of biological particles in reactor drum can be precisely controlled, (can be accurate to 0.1 second); So the bio oil composition that pyrolysis obtains is more consistent with concentration ratio, and this further optimization for product has very big advantage.
(2) temperature of ability subregion control pyrolytic process:
According to the pyrolysis principle, biomass can improve the productive rate and the oil product of bio oil in different warm area pyrolysis.Because in biomass pyrolysis process, temperature is a very significant effects factor, and it all has very big influence to pyrolysis product distribution, component, productive rate and pyrolysis gas calorific value.What of gas in the biomass pyrolytic final product, oil, each accounting example of charcoal have very big-difference with the height of temperature of reaction and the speed of rate of heating.Generally speaking, low temperature, long-term pyrolysis at a slow speed of being detained are mainly used in the output that increases charcoal to greatest extent, and its mass yield and energy productive rate reach 30% and 50% (massfraction) respectively.If temperature is during less than 600 ℃ conventional pyrolysis and adopt medium speed of reaction, then the productive rate of bio oil, non-condensable gas and charcoal is equal basically; If adopt the flash pyrolysis temperature in 500～650 ℃ of scopes, can increase the output of bio oil, the bio oil productive rate can be up to 80% (massfraction); Same flash pyrolysis if temperature is higher than 700 ℃, under residence time, can increase the gaseous product output in very high speed of reaction and the gas phase of extremely lacking, and its productive rate can reach 80% (massfraction).
Although fluidized bed pyrolysis reactor can adopt electrically heated; Also can adopt the control of thermopair subregion; But because material is in fluidized state in the fluidized-bed, tend to occur air-teturning mixed phenomenon, the heat convection current is transmitted; Make temperature in the reactor drum than uniform distribution, be difficult to through thermopair controlled temperature subregion.Do not have fluidisation and air-teturning mixed phenomenon in this spiral pyrolysis reactor, heat exchange pattern is leaned in the heat transmission fully, so rate of heat transfer is little, is convenient to temperature control, and this helps the optimization of product.
The present invention directly generates bio oil with biomass pyrolytic through the spiral pyrolysis installation, not only is convenient to store transportation, and the bio oil controllable component, be prone to refining and extract chemical.
