Description
本発明は、使用済みの電気電子機器の有用金属の回収装置に関する。 The present invention relates to a useful metal recovery device for used electrical and electronic equipment.
例えばプリント基板から金属を回収する装置が提案されている。
特許文献１は、プリント基板を加熱炉で３００〜４５０度に加熱することで、樹脂からガスを放出させ、ガス放出によって樹脂を消失する。
特許文献１では、加熱炉でのプリント基板の加熱を、大気中のような酸素含有雰囲気中で行う。酸素含有雰囲気中で加熱することで、樹脂からハロゲン化炭化水素の他に炭酸ガスを放出させ、還元雰囲気中でプリント基板を加熱する場合と比較して、ハロゲン化炭化水素の発生量を減らしている。
特許文献２は、容器内で空気を供給することなくプリント基板を加熱することで樹脂を炭化させる。また、容器内で発生した水分、炭酸ガス、ハロゲン物質ガスは、容器内の圧力が高まると容器外に排出している。
特許文献３は、プラスチック・金属積層体廃棄物を、空気を断った状態でプラスチック加熱分解機中に供給することにより、プラスチック分は無酸素下で熱分解ガス化され、ガス／タールといった気体成分と固体の炭化物粒子にしている。
For example, an apparatus for recovering metal from a printed circuit board has been proposed.
In Patent Document 1, a printed circuit board is heated to 300 to 450 degrees in a heating furnace to release a gas from the resin, and the resin disappears by the gas release.
In Patent Document 1, heating of a printed board in a heating furnace is performed in an oxygen-containing atmosphere such as the air. By heating in an oxygen-containing atmosphere, carbon dioxide gas is released from the resin in addition to halogenated hydrocarbons, and the amount of halogenated hydrocarbons generated is reduced compared to heating a printed circuit board in a reducing atmosphere. Yes.
Patent document 2 carbonizes resin by heating a printed circuit board, without supplying air in a container. Further, moisture, carbon dioxide gas, and halogen substance gas generated in the container are discharged out of the container when the pressure in the container increases.
Patent Document 3 discloses that plastic / metal laminate waste is supplied into a plastic pyrolysis machine in a state where the air is cut off, so that the plastic component is pyrolyzed and gasified in the absence of oxygen, and a gas component such as gas / tar. And solid carbide particles.
しかし、特許文献１のように、酸素含有雰囲気中で加熱すると、燃焼し高温下にさらされるとともに酸化が生じてしまう。
また、特許文献２では、容器内で発生した水分、炭酸ガス、ハロゲン物質ガスの排出は、内部圧力が高まった場合に行うため、ガス化した物質がタール状となって金属に大量に再付着してしまう。
また、特許文献３では、プラスチック・金属積層体廃棄物の供給は、空気を断った状態で行うとしているが、生成ガスをプラスチック・金属積層体廃棄物に直接接触させており、燃焼のための空気を供給している。また、生成ガス温度の調整のために、プラスチック加熱分解機中に二次空気が吹き込まれている。従って、特許文献３では、燃焼によって高温下にさらされるとともに酸化が生じてしまう。
However, as in Patent Document 1, when heated in an oxygen-containing atmosphere, it burns and is exposed to high temperatures and oxidizes.
Further, in Patent Document 2, since the moisture, carbon dioxide gas, and halogen substance gas generated in the container are discharged when the internal pressure increases, the gasified substance becomes tar and reattaches to the metal in large quantities. Resulting in.
In Patent Document 3, the plastic / metal laminate waste is supplied in a state where the air is cut off, but the generated gas is in direct contact with the plastic / metal laminate waste, Air is supplied. Also, secondary air is blown into the plastic thermal cracker for adjusting the product gas temperature. Therefore, in patent document 3, oxidation will arise while being exposed to high temperature by combustion.
そこで本発明は、金属以外の物質を、燃焼させることなく炭化させ、気体成分を除去することで、金属へのタール付着をなくし、金属表面を剥離しやすい炭化物だけで被覆した状態とすることで、その後の金属回収を容易にすることができる金属回収装置を提供することを目的とする。 Therefore, the present invention carbonizes a substance other than metal without burning it, and removes the gas component, thereby eliminating tar adhesion to the metal and making the metal surface covered only with carbide that is easy to peel off. An object of the present invention is to provide a metal recovery apparatus that can facilitate subsequent metal recovery.

In this embodiment, the second processing container 3 and the heating chamber 4 are partitioned by a plate member 4a having a vent hole, and the combustion gas is provided in the second processing container 3 with a combustion gas outlet 4b, so that the combustion gas is heated in the heating chamber. 4 to be introduced into the second processing container 3. It should be noted that at least the second processing container 3 is not provided with an air inlet, and no new air is introduced into the second processing container 3.
The discharge pipe 5 is provided so as to open downstream in the suction pipe 8. The air supplied from the blower 9 is guided from the suction pipe 8 to the combustion chamber 6, but the discharge pipe 5 becomes negative pressure by the air flowing through the suction pipe 8, and the gas in the discharge pipe 5 flows out.
Here, the recovered resource 1 is a resource including metal and resin, such as a printed circuit board, a motor component, and a capacitor separated from the recovered electrical appliances and machinery.
第１の処理容器２には蓋が設けられており、回収資源１を第１の処理容器２内に投入後に蓋を閉じ、蓋を閉じた状態では、排出管５以外から気体が第１の処理容器２内に流入しない。ただし、本実施例のように第２の処理容器３に第１の処理容器２を収容する場合には、第１の処理容器２の密閉度は高くなくてもよい。
本実施例のように処理容器として、第１の処理容器２と第２の処理容器３とで構成する場合には、第２の処理容器３内に複数の第１の処理容器２を収容することができる。同じ回収資源１をそれぞれの第１の処理容器２に収容してもよいが、例えばプリント回路基板だけを分別して第１の処理容器２に収容し、モータ部品だけを別の第１の処理容器２に収容することで、第２の処理容器３内での加熱時間や加熱温度を、第１の処理容器２毎に異ならせることができる。
The first processing container 2 is provided with a lid, and after the recovered resource 1 is put into the first processing container 2, the lid is closed. It does not flow into the processing container 2. However, when the first processing container 2 is accommodated in the second processing container 3 as in the present embodiment, the sealing degree of the first processing container 2 may not be high.
In the case where the first processing container 2 and the second processing container 3 are used as processing containers as in the present embodiment, a plurality of first processing containers 2 are accommodated in the second processing container 3. be able to. The same recovered resource 1 may be accommodated in each first processing container 2, but for example, only the printed circuit board is separated and accommodated in the first processing container 2, and only the motor component is separated in another first processing container. By accommodating in 2, the heating time and heating temperature in the 2nd processing container 3 can be varied for every 1st processing container 2. FIG.
排出管５は、第１の処理容器２に設けられている。排出管５は、一端が第１の処理容器２内に位置し、他端が吸引管８内に位置している。排出管５の他端は、吸引管８内において下流側に向けて開口させる。従って、排出管５内の気体は、吸引管８を流れる空気によって導出される。
第２の処理容器３は、加熱室４が隣接し、加熱室４によって加熱される。第１の処理容器２及び第２の処理容器３内の温度は、２５０〜４００度が適している。加熱温度は金属以外の樹脂をはじめとする有機物の炭化に必要な温度とし、１８０度以下では十分でない。
加熱室４には、燃焼室６の燃焼ガスが導かれる。加熱室４とは別に燃焼室６を設けることで、加熱室４の温度の調整が容易となり、加熱温度を２５０〜４００度程度の温度に維持しやすくなる。
The discharge pipe 5 is provided in the first processing container 2. The discharge pipe 5 has one end located in the first processing container 2 and the other end located in the suction pipe 8. The other end of the discharge pipe 5 is opened toward the downstream side in the suction pipe 8. Therefore, the gas in the discharge pipe 5 is led out by the air flowing through the suction pipe 8.
The second processing container 3 is adjacent to the heating chamber 4 and is heated by the heating chamber 4. As for the temperature in the 1st processing container 2 and the 2nd processing container 3, 250-400 degree | times is suitable. The heating temperature is a temperature necessary for carbonization of organic substances including resins other than metals, and 180 degrees or less is not sufficient.
The combustion gas in the combustion chamber 6 is guided to the heating chamber 4. By providing the combustion chamber 6 separately from the heating chamber 4, the temperature of the heating chamber 4 can be easily adjusted, and the heating temperature can be easily maintained at a temperature of about 250 to 400 degrees.
吸引管８にはブロワー９が設けられ、ブロワー９によって、排出管５から流出させる気体を燃焼室６に導いている。第１の処理容器２内で発生する気体は、第１の処理容器２の温度上昇により、排出管５の一端から他端に流れ、排出管５の他端から吸引管８に流出する。従って、第１の処理容器２内で発生するタール成分は、発生とともに速やかに第１の処理容器２外に排出され、第１の処理容器２内に残留しないため、第１の処理容器２内でタール成分が付着することを防止できる。
ブロワー９は、排出管５からの気体排出をするもので、小さい風量で運転する。
第１の処理容器２には、内壁面に多数のセラミックボール１０を配設している。多数のセラミックボール１０を配設することで第１の処理容器２内の温度を効果的に維持するとともに電磁波を作用させ、高温度を一定に維持することができる。
The suction pipe 8 is provided with a blower 9, and the blower 9 guides the gas flowing out from the discharge pipe 5 to the combustion chamber 6. The gas generated in the first processing container 2 flows from one end of the discharge pipe 5 to the other end and flows out from the other end of the discharge pipe 5 to the suction pipe 8 due to the temperature rise of the first processing container 2. Accordingly, the tar component generated in the first processing container 2 is immediately discharged to the outside of the first processing container 2 as it is generated, and does not remain in the first processing container 2. Can prevent tar components from adhering.
The blower 9 discharges gas from the discharge pipe 5 and operates with a small air volume.
In the first processing container 2, a large number of ceramic balls 10 are arranged on the inner wall surface. By disposing a large number of ceramic balls 10, the temperature in the first processing vessel 2 can be effectively maintained and electromagnetic waves can be applied to keep the high temperature constant.
以下に本装置を用いた処理方法について説明する。
燃焼室６及びバーナー７を運転し、燃焼ガスを加熱室４に導く。
第２の処理容器３は、加熱室４によって加熱され２５０〜４００度に維持される。
第１の処理容器２は、あらかじめ第２の処理容器３内に収容しておくか、第２の処理容器３内が所定の温度に上昇した後に収容する。
第１の処理容器２が２５０〜４００度に加熱されることで、回収資源１に含まれている樹脂、その他の有機物は、炭化するとともにガス化する。第１の処理容器２には、第１の処理容器２外からの気体の流入がなく、第１の処理容器２内で発生する気体は排出管５から排出させる。第１の処理容器２内には新たな空気が導入されないため、第１の処理容器２内の有機物は、燃焼することなく炭化される。従って、タール成分のない炭化成分だけが金属表面に存在する状態にできる。
A processing method using this apparatus will be described below.
The combustion chamber 6 and the burner 7 are operated, and the combustion gas is guided to the heating chamber 4.
The second processing container 3 is heated by the heating chamber 4 and maintained at 250 to 400 degrees.
The first processing container 2 is stored in the second processing container 3 in advance, or is stored after the inside of the second processing container 3 has risen to a predetermined temperature.
By heating the first processing container 2 to 250 to 400 degrees, the resin and other organic substances contained in the recovered resource 1 are carbonized and gasified. There is no inflow of gas from outside the first processing container 2 to the first processing container 2, and the gas generated in the first processing container 2 is discharged from the discharge pipe 5. Since new air is not introduced into the first processing container 2, the organic matter in the first processing container 2 is carbonized without burning. Accordingly, only the carbonized component having no tar component can be present on the metal surface.
このように、本装置を用いて処理を行うと、金属は、タール成分のない炭化成分だけが表面を覆った状態にすることができる。従って、本装置を用いた処理を行った後の金属は、炭化物を金属から容易に剥離できる。また、金属表面に存在する炭化物によって金属は酸化されていない。 Thus, when processing is performed using this apparatus, the metal can be in a state in which only the carbonized component having no tar component covers the surface. Accordingly, the metal after the treatment using this apparatus can easily peel the carbide from the metal. Further, the metal is not oxidized by the carbides present on the metal surface.

回転軸２１ａの軸受け部には、カバー２３が設けられ、カバー２３には、排出管２４を設けている。排出管２４は、一端がカバー２３内に位置し、他端が吸引管８内に位置している。排出管２４の他端は、吸引管８内において下流側に向けて開口させる。従って、排出管２４内の気体は、吸引管８を流れる空気によって導出され、カバー２３内は負圧となり、カバー２３から回転軸２１ａの軸受け部に外部空気が導入されることを防止できる。
排出管２４を設けることで、回転軸２１ａの軸受け部を通って第１の処理容器２０内に外部から空気が流入することを防止でき、燃焼を生じることなく炭化させることができる。
第１の処理容器２０には、回収資源１を投入する投入口２０ａと、炭化処理後の回収資源１を排出する排出口２０ｂとを備えている。投入口２０ａ及び排出口２０ｂは、炭化処理中は閉じられており、第１の処理容器２０内に外部から空気が流入することはない。
