Description
本発明は飲料の包装容器、食品（菓子等を含む）の包装材、医薬品の包装材等に広く使用されている、紙にアルミ箔を積層した包装材、又は紙にアルミ箔と樹脂フィルムを積層した包装材（以下、アルミ−紙系廃棄物と総称する）の廃棄物を資源化するためのシステムに関する。 The present invention is widely used for packaging containers for beverages, packaging materials for food (including confectionery), packaging materials for pharmaceuticals, etc., packaging materials in which aluminum foil is laminated on paper, or aluminum foil and resin film on paper. The present invention relates to a system for recycling waste of stacked packaging materials (hereinafter collectively referred to as aluminum-paper waste).
従来からパルパー装置にて故紙からパルプ分を回収し、リサイクルする方法は公知である。
例えば特許文献１は、アルミ，プラスチック，紙の複合材料をパルパーに投入し、パルプを回収した残部のアルミ，プラスチック分を沈降タンクを用いて精製する技術を開示するが、工程が複雑でパルプの回収やアルミの回収が不充分であった。
また、処理工程から発生する排水の処理装置も必要であった。
特許文献２は、液体カートン廃棄物をパルパーに投入し、パルプを除去した残りをガス化してアルミを回収する技術を開示するが、パルプの回収が不充分であり、アルミ側にパルプが残っているとガス化する際にパルプ分が炭化し、回収されるアルミの品質が低下する問題があった。
Conventionally, a method for collecting and recycling pulp from waste paper using a pulper device is known.
For example, Patent Document 1 discloses a technology in which a composite material of aluminum, plastic, and paper is put into a pulper and the remaining aluminum and plastic content recovered from the pulp is refined using a sedimentation tank. Recovery and aluminum recovery were inadequate.
In addition, a treatment apparatus for waste water generated from the treatment process is also required.
Patent Document 2 discloses a technique in which liquid carton waste is put into a pulper, and the remaining pulp removed is gasified to recover aluminum. However, the recovery of the pulp is insufficient, and the pulp remains on the aluminum side. When it gasifies, there is a problem that the pulp content is carbonized and the quality of the recovered aluminum is deteriorated.
本発明は、アルミ及びパルプの回収精度が高く、当該回収処理に伴う排水処理が不要となるアルミ−紙系廃棄物の資源化システムの提供を目的とする。 An object of the present invention is to provide an aluminum-paper waste recycling system that has high aluminum and pulp recovery accuracy and does not require wastewater treatment associated with the recovery process.
本発明に係るアルミ−紙系廃棄物の資源化システムは、パルプスラリーとアルミ等を分離するためのパルプ分離装置と、分離されたアルミ等からさらにパルプ分を回収するための洗浄装置と、洗浄されたアルミ等から脱水するための脱水装置と、分離されたパルプスラリーの濃縮装置と、濃縮されたパルプスラリーからパルプシートを得るためのパルプシート製造装置とを備えたことを特徴とする。
ここで、アルミ−紙系廃棄物と表現したのは、飲料の包装容器（パック）、菓子類や食品の包装材、医薬品等の包装材には紙にアルミ箔を積層したものの他に樹脂フィルムにアルミ箔を積層又は、蒸着したものに紙を積層したものも広く使用されている。
これらの包装材からパルパーにてパルプ分を回収する際にパルプ分の回収が不充分であると回収されたアルミと樹脂フィルムとの積層体を乾留によりガス化する際にパルプ分が炭化したまま残ってしまい、回収されるアルミの純度が低下する問題が生じる。
そこで、本発明は複合包装材からパルプを充分に回収できるようにした点に特徴があり、アルミに樹脂フィルムがそのまま積層されたものも含める趣旨でアルミ等と表現する。
The resource recycling system for aluminum-paper waste according to the present invention includes a pulp separator for separating pulp slurry and aluminum, a cleaning device for further recovering pulp from the separated aluminum, and a cleaning And a pulp sheet manufacturing apparatus for obtaining a pulp sheet from the concentrated pulp slurry.
Here, the expression “aluminum-paper waste” is a resin film in addition to a paper packaging container (pack), a packaging material for confectionery and food, a packaging material for pharmaceuticals, etc., in which aluminum foil is laminated on paper. In addition, aluminum foil laminated or vapor-deposited on paper is also widely used.
When the pulp content is recovered from these packaging materials with the pulper, the pulp content remains carbonized when the recovered aluminum / resin film laminate is gasified by dry distillation. It remains, and the problem which the purity of the aluminum collect | recovered falls arises.
Therefore, the present invention is characterized in that the pulp can be sufficiently recovered from the composite packaging material, and is expressed as aluminum or the like for the purpose of including the one in which the resin film is laminated on aluminum as it is.
さらに本発明にあっては、前記脱水装置、パルプスラリーの濃縮装置及びパルプシート製造装置から回収された水を前記パルプ分離及び洗浄装置に再利用することで系外に排水しないことを特徴とする。
このように脱水装置やパルプスラリーの濃縮装置及びパルプシート製造装置等、本システムの系から発生する水をそのままパルプ分離装置、洗浄装置に使用する水に用いることができるので完全なクローズドシステムになり、排水処理装置が不要となる。
なお、パルプシートには水分が２０〜４０％含まれているので系内にて不足する水は補給する。
Furthermore, in the present invention, the water recovered from the dewatering device, the pulp slurry concentrating device, and the pulp sheet manufacturing device is reused in the pulp separation and washing device so that it is not drained outside the system. .
In this way, the water generated from the system such as dehydrator, pulp slurry concentrator and pulp sheet manufacturing device can be used as it is for the water used in the pulp separator and washing device. The waste water treatment equipment becomes unnecessary.
Since the pulp sheet contains 20 to 40% of water, water that is insufficient in the system is replenished.
本発明にあって、パルプ分を精度高く回収することでその後のアルミ等の乾留処理にて炭化物を低減できることから、前記パルプ分離装置は処理槽を有し、当該処理槽内に撹拌羽根と、相対的に孔の大きい大孔プレート及びその外側に又は下に孔の小さい小孔プレートを重ねた二重スクリーンであるのが好ましく、前記洗浄装置は、パルプは通過するがアルミ等は通過しないスリットからなる洗浄スクリーンであるのが好ましい。
このようにすると、アルミ資源の回収が容易になり、前記回収されたアルミ等を乾留処理し、ガス化成分を除去するための乾留装置を有する。
In the present invention, it is possible to reduce the carbide in the subsequent carbonization process such as aluminum by accurately recovering the pulp content, the pulp separation device has a treatment tank, stirring blades in the treatment tank, Preferably, it is a double screen in which a large hole plate with relatively large holes and a small hole plate with small holes on the outside or below are stacked, and the cleaning device is a slit through which pulp passes but aluminum does not pass. A cleaning screen consisting of
If it does in this way, collection | recovery of aluminum resources will become easy, and it has a dry distillation apparatus for carrying out the dry distillation process of the said collect | recovered aluminum etc. and removing a gasification component.
本発明にあっては、包装材から効率よくパルプを回収でき、しかも系外に放出される排水がないので、従来コストアップの大きな要因であった排水処理が不要である。
また、包装材からパルプ分が除去された残りのアルミ箔又はアルミ箔と樹脂フィルム（シート）との積層体は還元条件下で、アルミが溶融しない２００〜６２０℃以下の温度でガス化することで樹脂分が除去され、純度の高い金属アルミを資源として回収できる。
In the present invention, since the pulp can be efficiently recovered from the packaging material and there is no waste water discharged outside the system, waste water treatment which has been a major factor in increasing the cost is unnecessary.
The remaining aluminum foil from which the pulp content is removed from the packaging material or the laminate of the aluminum foil and the resin film (sheet) is gasified at a temperature of 200 to 620 ° C. or less at which the aluminum does not melt under reducing conditions. In this way, the resin content is removed and high-purity metal aluminum can be recovered as a resource.
