Description
Technical field
The present invention relates to biomass-making alcohol fuel field, particularly a kind of raw material conveying device that supplies the lignocellulosic pretreatment unit.
Background technology
Utilize plant production alcohol fuels such as agricultural crop straw to become a new energy resource industrial chain.Because agricultural crop straw and forestry residue components are complicated, the water content of Different Crop, hardness, crush resistance etc. have very big-difference, have brought very big difficulty therefore for the cellulosic preprocessing process.In preprocessing process, usually need solid material be transported to high temperature high pressure device by the normal temperature and pressure environment and handle.Traditional method is to carry out the processing of discontinuity through a cavity that has pressurization, pressure relief device is set, but this method inefficiency, energy consumption is big, and can not satisfy the continuity operation of suitability for industrialized production.A kind of solution is raw material to be processed slurries utilize pumping, and this has certain requirement (8%-30%) to the charging solid concentration, and high solids content (＞13.4%) material need be processed slurry feed at higher temperature (99 ℃).Another kind method is to make the material plug that material forms is enough to seal gases at high pressure through the method for pushing; Get into the pretreatment reaction device through piston or screw drive then; Under this condition, the fibrous raw material of approximate dry state can be realized the mechanical tear and the institutional framework change of lignocellulosic in high shear force and the multiple action that friction generates heat down.
Patent CN1309602A has reported a kind of equipment of supply 90% chemical cellulose material heap.Be provided with screw rod and the reciprocal annular piston coaxial with it in this equipment barrel, be provided with conical plug at barrel discharging opening place stifled.In the raw material feeding process, material is torn and promoted to screw rod, and back and forth annular piston compresses above-mentioned material, finally makes material form the compacting plug of cross section near the barrel cross section.The density of this plug is enough to resist the high steam impact of reactor, does not have the phenomenon of regurgitating of material, thereby has guaranteed material feeding high-pressure reactor.Patent CN2208589 has reported a kind of transport of string.This system adopts the screw conveying device of three mutually interconnected connections, and wherein first screw rod is a conical screw, is used to promote material, the inwall of feed cylinder be import big, go out young taper.The port of export at first screw rod feed cylinder has self-regulation spring backstop, can overcome the problem that continuous feed is prone to regurgitate under the High Pressure Difference state.In above-mentioned these methods, the material plug of closure forms through piston or the stifled extruding of awl, and this not only makes raw material bear higher temperature and pressure and causes sclerosis or keratinization, and has increased equipment investment cost.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of fibre material transport, can guarantee that material is delivered to the high-temperature high-voltage reaction device continuously and stably, prevents that high-temperature steam from regurgitating, and reduces the fibre material keratinization, and this equipment is simple, and is easy and simple to handle.
Fibre material transport of the present invention comprises hopper, barrel and screw arbor assembly, and wherein hopper is positioned at an end of barrel top charging; Screw rod is located at barrel inside, and the tube wall of barrel is the sandwich that comprises inner and outer wall, feeds cooling fluid in the interlayer; From barrel discharge port end meter; In barrel 3%～50% length range, preferably in barrel 5%～20% length range, at least one is set perpendicular to the axial ring baffle of barrel.
In the fibre material transport of the present invention, ring baffle is provided with 1～10, is preferably 2～5; Ring baffle is welded on the barrel inwall; The ring width of ring baffle be between barrel and the screw rod distance 5%～90%, be preferably 30%～70%, can normally load and unload to guarantee screw rod.
In the fibre material transport of the present invention, screw rod is preferably the combined threaded rod of isometrical screw rod and conical screw, and feed end is isometrical screw rod, and discharge end is a conical screw, and the conical screw butt end is connected with isometrical screw rod.The length ratio of isometrical screw rod and conical screw is 4: 1～1: 4, is preferably 2: 1～1: 2.
In the fibre material transport of the present invention, isometrical screw diameter accounts for 70%～90% of barrel inner diameter, and the conical screw diameter accounts for 60%～90% (the barrel inner diameter that all refers to the screw rod present position) of barrel inner diameter.The isometrical screw channel degree of depth can be that the spiral groove depth of conical screw diminishes along with diminishing of screw diameter gradually uniformly.Among the present invention, the diameter of screw rod refers to the diameter at spiral shell rib outer rim place.
In the fibre material transport of the present invention; The barrel inner diameter changes with the variation of screw diameter; Being the little special shape of import large outlet, is straight shape tube inwall at isometrical screw portion, and is the taper barrel that adapts to conical screw at conical screw barrel inwall partly.
In the fibre material transport of the present invention, the barrel outer diameter can change with the variation of barrel inner diameter; Preferred barrel outer diameter is constant, and the interlayer between the inner and outer wall contains cooling fluid, and the amount of cooling fluid reaches maximum near screw head.
Beneficial effect of the present invention is:
1, the design of ring baffle is effectively pushed material and is formed material plug among the present invention; Prevent the steam backward; The quantity of ring baffle can be according to the actual conditions setting; Form the material plug and can stop the impact of the high steam in the reactor and do not form to regurgitate and get final product that it is excessively densified to have avoided material to fill in, and helps the activation of material.
2, the screw arbor assembly of the present invention's employing has combined the advantage of isometrical screw rod and conical screw, has not only guaranteed charging rate but also improved the material degree of grinding.
3, the interlayer between the barrel inner and outer wall of the present invention contains cooling fluid, and the amount of cooling fluid reaches maximum near screw head, can absorb the huge heat that the screw head extruding raw material is produced, and reaches better radiating effect.
4, apparatus of the present invention are simple, need not piston or high-pressure pump and just realized the conveying of material to the high-temperature high-voltage reaction device, reduced equipment investment cost.
