Abstract

PROBLEM TO BE SOLVED: To recover useful metals simply and reliably from combustible members of the electronic substrates, without high-temperature fusion or oxidation, even when various types of electronic substrates are treated in a heat treatment furnace.SOLUTION: A method of recovering useful precious metals, and the like using a heat treatment furnace comprises a step of increasing the temperature of the inside of the heat treatment furnace, a step of introducing exhaust gas in a re-combustion furnace produced by re-combustion in the re-combustion furnace through an exhaust gas induction device and a step of processing the measured value of the temperature of the inside of the heat treatment furnace by a temperature management controller.

Description

本発明は、加熱処理炉を用いた有用貴金属等の回収方法及びその装置に関し、更に詳しくは、高額となる化石燃料を使用することなく、所定量の木片又は木炭を用いることで、主として各種電子基板（例えば、パソコン、携帯電話、ゲーム機等）等の有機廃棄物から可燃性部材のみを酸化させて有用貴金属類及び／又はセラミック類の回収作業を容易ならしめんとする極めて優れた加熱処理炉を用いた有用貴金属等の回収方法及びその装置に関するものである。  The present invention relates to a method and apparatus for recovering useful precious metals using a heat treatment furnace, and more specifically, by using a predetermined amount of wood chips or charcoal without using expensive fossil fuels, Extremely excellent heat treatment that facilitates the recovery of useful precious metals and / or ceramics by oxidizing only combustible materials from organic waste such as substrates (eg, personal computers, mobile phones, game machines, etc.) The present invention relates to a method and apparatus for recovering useful precious metals using a furnace.

従来、可燃性部材を有した有機廃棄物を焼却する炉としては、例えば、特開２００１−３０４５２０号公報所載のものや特開２０１２−２３８６号公報所載のものが存在する。
特開２００１−３０４５２０号公報 特開２０１２−２３８６号公報 Conventionally, as a furnace for incinerating organic waste having a flammable member, for example, those described in Japanese Patent Application Laid-Open No. 2001-304520 and those described in Japanese Patent Application Laid-Open No. 2012-2386 exist.
JP 2001-304520 A JP 2012-2386 A

即ち、上記前者特許文献に記載のものは、耐熱容器（焼却炉）の焼却処理室（炉）内に取り入れられる燃焼用空気の流入量を制限する流入空気制限手段と、前記燃焼用空気の空気通路上に磁場を形成して、該燃焼用空気を磁気処理する磁石手段と、前記焼却処理室の壁部に燃焼ガスの排出口を有した焼却炉であり、かかる構成にしてなる焼却炉においては、使用時に磁石手段を介して活性化された燃焼用空気により、僅かな流入量の空気によっても燃焼状態を継続して維持することが出来るだけでなく、流入空気制限手段を介して燃焼用空気量をも制限することで焼却処理室内の温度を７００℃以下の低温燃焼状態に維持し、その結果として廃棄物の燃焼により生じるダイオキシン類の生成を抑えることが出来るというものである。  That is, in the former patent document, an inflow air restricting means for restricting an inflow amount of combustion air introduced into an incineration processing chamber (furnace) of a heat-resistant container (incinerator), and air of the combustion air In an incinerator having a magnetic field formed on a passage and magnetically processing the combustion air, and an incinerator having a combustion gas discharge port in the wall of the incineration processing chamber. The combustion air activated through the magnet means during use can not only maintain the combustion state with a small amount of air, but also the combustion air through the inflow air restricting means. By limiting the amount of air, the temperature in the incineration chamber is maintained at a low temperature combustion state of 700 ° C. or lower, and as a result, generation of dioxins caused by combustion of waste can be suppressed.

一方、廃棄物の中には、各種電子基板（例えば、パソコン、携帯電話、ゲーム機等）が含まれることもある。  On the other hand, the waste may include various electronic boards (for example, personal computers, mobile phones, game machines, etc.).

尚、かかる各種電子基板には、金、銀、パラジウム等の有用貴金属類のみならずセラミック類が大量の樹脂等の可燃性部材に囲まれて存在しており、よって近年かかる各種電子基板から有用貴金属類やセラミック類を回収するリサイクル事業が行われてはいるが可燃性部材に囲まれた中から有用貴金属類やセラミック類を回収するには多額のコストがかかることとなり、費用対効果が高いとは決して言えないのが現状である。  In addition, such various electronic substrates include not only useful noble metals such as gold, silver and palladium, but also ceramics surrounded by a large amount of flammable members such as resin. Recycling business to collect precious metals and ceramics is carried out, but collecting valuable precious metals and ceramics from the surroundings of flammable materials is expensive and cost effective That is not the case.

よって、昨今、各種電子基板を上記構成の焼却処理炉で焼却することで可燃性部材から有用貴金属類やセラミック類を回収する試みがなされ、前記後者特許文献に記載の様に、熱源収容室内に発熱と吸熱とが可能な練炭を保熱材として配置するものがある。
かかる保熱材によれば炉内の温度が上昇すると周囲の雰囲気から吸熱し、炉内の温度が低下すると周囲へ放熱を行うことで炉内の温度変化を緩衝して炉内が所定の温度範囲内に維持するというものである。Therefore, recently, attempts have been made to recover useful noble metals and ceramics from combustible members by incinerating various electronic substrates in the incineration furnace configured as described above, and as described in the latter patent document, There is one in which briquettes capable of generating heat and endotherm are arranged as heat insulating materials.
According to such a heat insulating material, when the temperature in the furnace rises, heat is absorbed from the surrounding atmosphere, and when the temperature in the furnace falls, heat is dissipated to the surroundings to buffer the temperature change in the furnace and to keep the inside of the furnace at a predetermined temperature. It is to keep within the range.

即ち、炉内の温度を可燃性部材が燃焼、熱分解若しくは流動化する温度に保つことで、可燃性部材からの有用貴金属類やセラミック類の分離を容易にして回収する手間を簡易ならしめんとするものであるが、処理する各種電子基板に使用されている樹脂等の可燃性部材の量も処理ロット等により一定ではなく、よって炉内の瞬間的な温度変化に即対応して吸熱、放熱を瞬間的に行うことが出来ず、所謂タイムロスが生じることとなり、特にある容積を有した炉内全体の温度（特に炉内の鉛直方向での温度ムラ）を即均一化することが極めて難しく、よって各種電子基板から回収する有用貴金属類が高温融着したり酸化したりする等リサイクルという目的にとって致命的とも言える問題が生じていた。  In other words, by maintaining the temperature in the furnace at a temperature at which the combustible member burns, pyrolyzes or fluidizes, it is easy to separate and recover the valuable precious metals and ceramics from the combustible member. However, the amount of flammable members such as resin used for various electronic substrates to be processed is not constant depending on the processing lot, etc., and therefore endothermic in response to instantaneous temperature changes in the furnace, Heat dissipation cannot be performed instantaneously, so-called time loss occurs, and it is extremely difficult to immediately equalize the temperature of the entire furnace having a certain volume (particularly temperature unevenness in the vertical direction in the furnace). Therefore, there has been a problem that can be fatal for the purpose of recycling, such as high-temperature fusion or oxidation of useful precious metals recovered from various electronic substrates.

更に、上記練炭は、石炭を粉末成型したものであり、よって石炭の種類によっては、硫黄臭や鉱物臭が発生する場合のみならず、燃焼後の練炭殻には、微量ではあるが石炭由来の各種有害物質や重金属が含まれており、使用済の練炭を捨てる場所、所謂廃棄処理にコストがかかるいう問題のみならず排煙に含まれる炭化粒子の処理も必要であるという問題が生じていた。  Furthermore, the briquettes are those obtained by powder molding of coal. Therefore, depending on the type of coal, not only when a sulfur odor or mineral odor is generated, but the briquette shell after combustion is a small amount of coal-derived. Various harmful substances and heavy metals were included, and there was a problem that it was necessary to dispose of spent briquettes, so-called disposal treatment was costly, as well as treatment of carbonized particles contained in flue gas .

It is possible to rapidly lower the temperature from the high-temperature state of combustion to the downward direction, so that the next step is the introduction of re-burning furnace gas into the cooling tower (4) and the induction into the exhaust gas induction device (7). Is advantageous in that it can be performed at a safer temperature level.

更に、加熱処理炉（２）内の温度を６００℃±１００℃の雰囲気下に均一保持して使用することから、高温に耐える高価な材料を用いて炉を製造する必要がなく、よって、炉を構成する各種部品や部材等の材料費を低減することが出来るだけでなく、炉材の温度劣化をも防止して極めて長期間に渡って加熱処理炉（２）を有効に使用することが出来るという効果があるばかりか、空気導入量を調整することで加熱処理炉（２）内の温度６００℃±１００℃の雰囲気下に均一保持することから、有機廃棄物（２２）に具備された有用金属類等の種類によって該有用金属類等が酸化しない炉温に炉内の温度設定をより細かく調整することが出来るという利点がある。  Furthermore, since the temperature in the heat treatment furnace (2) is uniformly maintained in an atmosphere of 600 ° C. ± 100 ° C., it is not necessary to manufacture the furnace using an expensive material that can withstand high temperatures. In addition to reducing the material costs of the various parts and members that make up the furnace, it is also possible to effectively use the heat treatment furnace (2) for an extremely long period of time by preventing temperature deterioration of the furnace material. Not only has the effect of being able to do this, but also the organic waste (22) is provided because it can be uniformly maintained in an atmosphere of a temperature of 600 ° C. ± 100 ° C. in the heat treatment furnace (2) by adjusting the amount of air introduced.

By effectively using the high-temperature gas removed by recombustion, the temperature of the treatment reaction part (2c) of the heat treatment furnace (2) is instantaneously increased without interposing other devices, and organic waste ( 22) can be processed.

更に、上記実施形態において、加熱処理炉（２）及び／又は再燃焼炉（３）若しくは加熱処理炉（２）と再燃焼炉（３）の間又はその近傍には、熱電変換素子を用いた熱電発電手段が設けられていてもよく、この場合には、熱エネルギーを現場にて電力エネルギーに簡単に変換して、例えば、各弁、ファンのみならず温度管理制御装置（６）で電源として利用することも出来、又可動部が無いために長寿命、省スペースの利点を有用基金属等の回収装置に具備させて装置の付加価値を高めることが出来るという利点がある。  Furthermore, in the said embodiment, the thermoelectric conversion element was used between the heat processing furnace (2) and / or the recombustion furnace (3) or between the heat processing furnace (2) and the recombustion furnace (3), or its vicinity.
