Description

Papermaking solid waste process for producing line
Technical field
The present invention relates to waste sludge from paper mill processing technology field, be specifically related to a kind of papermaking solid waste process for producing line.
Background technology
The waste sludge from paper mill handling problems in annual more than one hundred million tons of the current whole nation has caused the very big concern of governments at all levels, and government is also in the disposal way of positive reasonable, and this is last in the large pollution problem of current paper industry three is also the most unmanageable problem.
Along with protecting national resource and reducing the reinforcement of environmental pollution consciousness, the waste paper of China is recycled large development.But a considerable amount of waste sludge from paper mill is created in waste paper recycling process.
According to incompletely statistics, at present, often produce waste sludge from paper mill, particularly regenerated papermaking that 6,000,000 tons of paper will produce more than 100 ten thousand tons, its waste residue material produced is just more more complicated, and it is mainly containing waste plastics, old metal, timber and other various impurity.
For above-mentioned waste residue, in the past and existing recovery and treatment method mainly: manually pick and add WATER-WASHING METHOD method of distributing, it is that all the other all adopt WATER-WASHING METHOD, and natant light plastic is sorted out first by manually old metal and plastics being picked out in debris dump.Adopt and carry out sorting recovery in this way, phase organic efficiency is low, and, be merely able to reclaim the metal in waste residue and plastics, resource utilization is not high, and other materials can not be utilized again, still can only rely on landfill or burning, so, still keep away the pollution of unavoidable environment and the waste of resource.
As Chinese invention patent: papermaking waste recovery system, the patent No. is: CN201310002114.5, and it discloses a kind of papermaking waste recovery system, comprising: primary mill, type fine disintegrating machine and top are provided with the conveyer belt of magnetic separator and vortex flow device.Magnetic separator separable go out ferrous metal in discarded object, reduce the wearing and tearing to follow-up equipment, and can resource reclaim be reached; Vortex flow device separable go out aluminium and copper metal and reach resource reclaim.
In such scheme, it is merely able to the metallics filtered out in papermaking waste, and pollutes and filter out other materials and be used, and still there is the deficiency of pollution and the wasting of resources.
For another example Chinese invention patent: utilize papermaking waste to be made into the method for based plate, CN200910272742.9, comprise the following steps: A. chooses by weight and cuts off dedusting material slag, screenings, paper mill sludge and boiler flue gas desulfurization gypsum, mixing, after oven dry, obtaining powder-mixed raw material through pulverizing; B. choose powder-mixed raw material, magnesium lignosulfonate or calcium lignosulfonate solution and straw particle by weight, mix, obtain sheet material base stock; C. sheet material base stock is loaded in mould, and implant strip skeleton or latticed skeleton, strike off, with forcing press by compressing for the sheet material base stock rear demoulding, after sizing, dry process, namely obtain sheet forming goods.Fully utilized multiple papermaking waste all sidedly, simple process, production cost is low.
In the above-mentioned patent, it utilizes waste sludge from paper mill to produce sheet material, although full use waste sludge from paper mill, but the various materials in waste residue do not screen by respectively, recycle respectively, such as metal species and Plastic material are used for making sheet material, its essence is also a kind of waste.
