Abstract
The invention discloses a method for harmless treatment of waste residue in paper making. According to the method, light-weight plastic mixture, cellulose residue, magnetic and non-magnetic metals and small heavy hard plastics and the like are separated from waste residues in paper making through a pneumatic vibration screen, an incineration boiler, a magnetic separation device, a rolling screen and eddy current, namely, all the parts in the waste residue in paper making are continuously separated by machines so that all the waste sources are optimally disposed to achieve harmless treatment by changing waste residues of paper making into valuables, so that environmental pollution accidents are prevented. The method is necessary for economic sustainable development.
Description
Technical field
The present invention relates to a kind of waste sludge from paper mill integrated conduct method technical field.
Background technology
According to statistics, 6,000,000 tons of paper of every production will produce the waste sludge from paper mill, particularly regenerated papermaking of more than 100 ten thousand tons, and the waste residue material of its generation is just more more complicated, and it contains more waste plastics, a small amount of old metal and other various impurity.In the past and existing processing method be mainly landfill method, WATER-WASHING METHOD sorting, comminution granulation and burning method, it is not high that these methods all exist resource utilization, pollutes the problems such as comparatively serious.
As landfill method, severe contamination local ecological environment.
Manually pick and add WATER-WASHING METHOD method of distributing, it is first by manually metal (pop can, iron wire etc.) and valuable plastics (mineral water bottle and so on) being picked out in rubbish heap, and all the other all adopt WATER-WASHING METHOD, and natant light plastic is sorted out.Can the come out light plastic of moisture content 60%, for selling or granulation.Someone will sell 20 yuan of one bag of heavy plastic garbage (approximately 500 kilograms), and nobody will just pile, remaining rubbish (body refuse, rubble, cullet etc.) no matter.Adopt sorting in this way, inefficiency; Sort untotally, can only sort out natant light plastic; Secondary pollution is also large, and sewage, mud crossing current, be difficult in place get a foothold, and residual garbage is many.
Comminution granulation is that plastics sorting factory sells granulation factory production plastic pellet the light plastic of washing out.Granulation producer is all the granulation of burning coal naked light, and exhaust emission is serious, and produces carcinogenic Qi Ti bioxin.
The waste sludge from paper mill of national annual more than one hundred million tons and the waste plastics handling problems causing thereof have caused the very big concern of governments at all levels at present, government is also in the positive disposal way of reasonable, and this is in the large pollution problem of current paper industry three to be also finally the most unmanageable problem.
Summary of the invention
Object of the present invention solves prior art problem exactly, and a kind of novel waste sludge from paper mill integrated conduct method is provided, and adopts integrated conduct method of the present invention, can not only make complicated waste paper waste residue harmless treatment, and twice laid to greatest extent.
For reaching above-mentioned purpose, the technical scheme that the present invention takes is as follows:
A kind of waste sludge from paper mill method for innocent treatment, comprises the steps:
1) isolate lightweight mixed waste plastic and paper pulp fiber slag by wind-force vibratory sieve, carry out fiber recovery by sending into slurrying workshop section after the fragmentation of paper pulp fiber slag, final superseded fiber fines mud send burning boiler after drying; The glass that pulping raw material filters out and stone carry out road surface landfill; Lightweight mixed waste plastic send chemical plant to do raw material;
2) magneticly elect magnetic metal material from the remaining waste material the inside of step 1);
3) by drum screen from step 2) remaining waste material the inside sub-elects bulk heavy duroplasts as industrial chemicals;
4) sub-elect nonmagnetic metal and fritter heavy duroplasts by vortex flow from the remaining waste material the inside of step 3), fritter heavy duroplasts is as industrial chemicals.
Further, the fibered plaster described in step 1) adopts semi-oriented belt press dehydration before drying, can be respectively fiber mud cake longitudinally, laterally with vertical to three-dimensional shearing force, reduce the moisture content of fibered plaster, can greatly reduce heat energy supply.Further, fibered plaster is dried time circulation and is adopted the tail gas of burning boiler to dry granulation, utilization rate can reach 90% and more than.
Waste sludge from paper mill method for innocent treatment of the present invention, by various piece continuous mechanized segmentation in waste sludge from paper mill, makes various waste resources obtain best processing approach, and realize and having turned waste into wealth, be also the inevitable requirement that realizes sustainable economic development.The present invention fully utilizes isolated all kinds of refuses according to its attribute, the products such as plastics recoverable manufacture strap, industrial packaging bag, regenerated plastics particle, oil maximize twice laid, substantially avoid secondary pollution.After papermaking waste plastics focuses on, can effectively change existing papermaking enterprise Treatment of Waste Plastics situation, greatly reduce soil pollution and energy resource consumption, can prevent the illegal transhipment of papermaking waste plastics simultaneously and illegally process, the serious accident that prevents the pollution of the environment occurs.
Below in conjunction with drawings and Examples, technical scheme of the present invention is done to clearly explanation:
Accompanying drawing explanation
Fig. 1 is waste sludge from paper mill method for innocent treatment process flow diagram of the present invention.
The specific embodiment
Embodiment 1
As shown in Figure 1, waste sludge from paper mill method for innocent treatment of the present invention, comprises the steps:
1) first the waste sludge from paper mill of waste sludge from paper mill field is isolated to lightweight mixed waste plastic and paper pulp fiber slag by wind-force vibratory sieve, the wind-force of wind-force vibratory sieve regulates and vibration frequency can regulate according to isolating effect, is as the criterion as far as possible lightweight mixed waste plastic is gone out to separate from different discharging openings with paper pulp fiber slag.After the fragmentation of paper pulp fiber slag, send into slurrying workshop section and carry out fiber recovery, final superseded fiber fines mud send burning boiler after drying; The glass that pulping raw material filters out and stone carry out road surface landfill or send cement plant etc.; Lightweight mixed waste plastic send chemical plant to do raw material, as refined oil, do decorating outer wall of building plate etc.
2) magneticly elect magnetic metal material from the remaining waste material the inside of step 1), as iron block, iron wire.
3) by drum screen from step 2) remaining waste material the inside sub-elects bulk heavy duroplasts as industrial chemicals.
4) sub-elect nonmagnetic metal aluminium etc. and fritter heavy duroplasts from the remaining waste material of step 3) the inside by vortex flow, fritter heavy duroplasts is equally as industrial chemicals.
Fibered plaster described in step 1) is preferential before drying adopts semi-oriented belt press dehydration, can be respectively fiber mud cake longitudinally, laterally with vertical to three-dimensional shearing force, reduce the moisture content of fibered plaster, can greatly reduce heat energy supply.Further, fibered plaster is dried time circulation and is adopted the tail gas of burning boiler to dry granulation, utilization rate can reach 90% and more than.
