(1) will send in the described classification seperator greater than 99% cassava vinasse as substratum dreg liquid through the water content that anaerobic fermentation is handled and separate, remove earth and ash content, obtain carving slag from the isolated cassava fiber of discharging opening, the water content of cassava fiber waste residue is lower than 85%;
(2) water content is lower than 85% cassava fiber waste residue and enters the feed hopper of pressafiner from defeated hopper, carries out further processed through pressafiner, and obtaining water content is the cassava fiber waste residue of 60-65%;
(3) be in the cassava fiber waste residue input drying unit of 60-65% with the water content that obtains, after vortex conveyor dryer, the dry separation of cyclone dust collectors, obtain the cassava fiber waste residue that water content is 25-30%, through the make-up machine granulation, make water content and be lower than 25% cassava fiber particle again.
Above-described method, the diameter of described cassava fiber particle is preferably 13-20mm, more preferably 16mm; Length is preferably 25-35mm, more preferably 30mm.
Compared with prior art, system and method advantage of the present invention is as follows:
1, system of the present invention is reasonable in design, and treatment effect is good, efficient is high, can realize moisture content is higher than that 99% cassava vinasse as substratum dreg liquid separates, dewaters, dry, granulation is handled, and makes the cassava fiber particle, realizes the recycling of cassava fiber.
2, described classification seperator in use, the driven by motor main shaft rotates, main shaft drives and separates cylindrical shell, separation helical rotation, wait to squeeze material from feed pipe enter separate cylindrical shell after, under the effect that separates spiral, realize separating, the water of separating separates cylindrical shell from screen mesh type discharges, and the material after the separation is discharged from discharging opening.Its rational in infrastructure, good separating effect, it can be that coarse-fibred cassava waste residue carries out separating of ash content and earth to main component, and dehydration part moisture.The water content of cassava waste residue can be reduced to about 85% after the classified separator for processing.
3, described pressafiner in use, the driven by motor main shaft rotates, thereby driving propelling worm, conveyor screw and little screen cloth rotates, waiting to squeeze material enters in the screen mesh type squeezing cylindrical shell from feed hopper, under the effect of the opposite conveyor screw of the hand of spiral, propelling worm, realize single pressing, water is discharged from screen mesh type squeezing cylindrical shell.Hydraulic system promotes the squeezing part, and pyramidal squeezing part inwardly motion diminishes discharging opening, realizes the twice pressing to material, and the water that squeezes out is discharged from screen mesh type squeezing cylindrical shell, perhaps enters in the cavity from little screen cloth, discharges from outlet pipe.It is rational in infrastructure, and is easy to use, and press dewatering is effective.Can be that coarse-fibred cassava waste residue effectively dewaters to main component, its water content can be reduced to 60-65% about from 85% through pressafiner of the present invention.
4, the present invention has adopted the classification solid-liquid isolation method, removes cassava ash content and anaerobic sludge in the useless wine with dregs to greatest extent.Poor liquid in the anaerobic fermentation surge tank pond mainly contains effective constituent crude fibre (composition), ash, mud.By the classification separator for processing, optionally obtain the crude fibre of cassava in the waste liquid, remove most of moisture content effectively.Cassava waste residue fiber after the separation is done further dehydration through pressafiner.Pressafiner adapts to coarse-fibred physical property characteristic, and waste residue water content behind pressafiner can be controlled in 60 ~ 65%, creates favorable conditions for next step oven dry reduces energy resource consumption.Drying unit is selected the mode of high temperature gas flow drying for use, device thermal efficiency height, technology is reliable, the physical characteristic that is fit to manioc waste＜65% moisture content, oven dry back manioc waste water content about 30%, this parameter is that can the cassava waste residue moulding, can smooth combustion in burner hearth, and the important indicator that reduces the boiler smoke dew point.The hot-blast stove of drying unit can act as a fuel with waste residue behind the drying and moulding, saves the outsourcing energy cost.
5, system and method for the present invention has realized that the alcohol industry boiler can burn the target that coal can burn waste residue, biogas again, has reduced the boiler quantity (three boilers of conventional use) of alcohol enterprise under the conventional deployment scenarios; The separate unit boiler is that the raising of cogeneration of heat and power type selecting boiler parameter and system effectiveness creates conditions.Adopt fractionation technique, classification dehydration technique, moulding combustion technology to improve the business system comprehensive utilization benefit, about 200 yuan of alcohol energy savings costs per ton have promoted enterprise's realization economic transition that relies on scientific and technological advances effectively.
