Abstract
The present invention relates to a technology for separating paper-plastic scraps, which mainly comprises the following steps: 1, when a reaction vessel filled with solvents reaches the temperature of 90 DEG C to 140 DEG C, the paper-plastic scraps are put into the reaction vessel with the weight ratio of the solvents to the paper-plastic scraps of 5 to 10: 0.5 to 1; 2, after the paper-plastic scraps are dissolved, the paper-plastic scraps are filtered and separated on a separator; 3, separated paper pulp is conveyed to a baking oven for baking treatment; and 4, liquid and plastics obtained by separating the paper pulp are separated for a second time by being conveyed to a high-speed separator, and then are conveyed to the baking oven for baking treatment. The technology has the advantages of waste utilization, recovery, regeneration, national resource saving, pollution prevention, biological environment protection, simple and practical technology and good effect.
Description
Technical field
The present invention relates to separating treatment technology, mainly is a kind of paper and plastic scraps separation process.
Background technology
Along with China economic construction ground is fast-developing, Chinese women are also more exquisite to the health of self.From before the cloth sanitary napkin use disposable paper composite sanitary napkin instead, use very extensive, and all there are several families or tens families in each big city of producer that produces sanitary napkin, just there is 600T in the big factory of annual paper and plastic scraps, and little factory goes out to have 200-300T, and annual all leftover pieces just have about the 5000T, owing to can not be embedded in below the soil, can only change money strength and move a burning burning to, it be carried out regeneration, waste a large amount of useful resources.The result still causes secondary pollution, can not thoroughly solve environmental issue, becomes a harm greatly of society and environmental protection.How leftover bits and pieces being separated is a great problem, does not also have technology can solve this difficult problem well in the past in the present invention.
Summary of the invention
The purpose of this invention is to provide a kind of paper and plastic scraps separation process that paper and plastic scraps is carried out regeneration.
The technical solution adopted for the present invention to solve the technical problems.This paper and plastic scraps separation process, 1), when the reaction pot that solvent is housed reaches 90-140 ℃ of temperature mainly comprise the steps to realize:, put paper and plastic scraps into, wherein the weight proportion of solvent and paper and plastic scraps is, solvent 5-10 part, paper and plastic scraps are 0.5-1 part; 2), paper and plastic scraps through the dissolving after, on seperator, carry out isolated by filtration; 3), the paper pulp that separates is sent to baking oven and dry processing; 4), the liquid after paper pulp isolated and plastics deliver to and carry out on the high speed separator separating of plastics and liquid for the second time, send plastics to baking oven again and dry processing.
The technical solution adopted for the present invention to solve the technical problems can also be further perfect.Described solvent adopts tetrachloro-ethylene, and optimum temperature and proportioning be, the temperature of reaction pot is at 120 ℃, the weight proportion of solvent and paper and plastic scraps 10: 1.Also can adopt the comminutor granulation through the plastics after the oven dry, paper pulp can be used for papermaking again.
1), twice laid the effect that the present invention is useful is:, national resources is saved in reclaiming.2), prevent to pollute, help the protection of ecological environment.3), features simple and practical process, effective.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.This paper and plastic scraps separation process, 1), adopt boiler and heat to reaction pot mainly comprises the steps to realize: by hot oil pipeline, when the reaction pot that tetrachloroethylene solvent is housed reaches 120 ℃ of left and right sides, put paper and plastic scraps into, wherein the weight proportion of tetrachloroethylene solvent and paper and plastic scraps is, tetrachloroethylene solvent: paper and plastic scraps is 10: 1, when temperature reaches 120 ℃ of left and right sides, dissolving plastic, the paper pulp foaming has been loose; 2), paper and plastic scraps through the dissolving after, on centrifugal separator, carry out isolated by filtration; 3), the paper pulp that separates is sent to about 100 ℃ of left and right sides baking ovens and dry processing; 4), the liquid after paper pulp isolated and plastics deliver to and carry out on the high speed separator separating of plastics and liquid for the second time, send baking oven to after plastics are separated and dry processing, again liquid are sent back to reaction pot or storage box is reused; 5), through the oven dry after plastics also can adopt the comminutor granulation, paper pulp can be used for papermaking again.
Claims (4)
1, a kind of paper and plastic scraps separation process, it is characterized in that, 1), when the reaction pot that solvent is housed reaches 90-140 ℃ of temperature mainly comprises the steps to realize:, put paper and plastic scraps into, wherein the weight proportion of solvent and paper and plastic scraps is, solvent 5-10 part, paper and plastic scraps are 0.5-1 part; 2), paper and plastic scraps through the dissolving after, on seperator, carry out isolated by filtration; 3), the paper pulp that separates is sent to baking oven and dry processing; 4), the liquid after paper pulp isolated and plastics deliver to and carry out on the high speed separator separating of plastics and liquid for the second time, send plastics to baking oven again and dry processing.
2, paper and plastic scraps separation process according to claim 1 is characterized in that: described solvent is a tetrachloro-ethylene.
3, paper and plastic scraps separation process according to claim 1 is characterized in that: the temperature of described optimum and proportioning be, the temperature of reaction pot is at 120 ℃, the weight proportion of solvent and paper and plastic scraps 10: 1.
4, according to claim 1 or 2 or 3 described paper and plastic scraps separation process, it is characterized in that: also can adopt the comminutor granulation through the plastics after the oven dry, paper pulp can be used for papermaking again.
