Description

本発明は水銀含有物からの水銀分離回収装置における炉体の構造に関するものである。 The present invention relates to the structure of a furnace body in an apparatus for separating and recovering mercury from mercury-containing materials.

水銀含有物、例えば、蛍光灯管の製造工程で発生する不良品や使用済みの蛍光灯管はガラス部分がリサイクルの対象とされるが、ガラス材料を回収して再利用するためには管内に封入されている水銀、ガラスに付着している水銀及び蛍光体粉末（蛍光物質）に含まれる水銀を分離回収する必要がある。
特に分離された蛍光物質は水銀含有量が高いことから、水銀の回収及び残分からレアメタルの回収が可能となる。 Mercury-containing materials such as defective products used in the manufacturing process of fluorescent lamp tubes and used fluorescent lamp tubes are subject to recycling, but in order to collect and reuse glass materials, It is necessary to separate and recover the enclosed mercury, the mercury adhering to the glass, and the mercury contained in the phosphor powder (fluorescent substance).
In particular, since the separated fluorescent substance has a high mercury content, it is possible to recover mercury and recover rare metals from the residue.

従来、例えば水銀を含む蛍光物質の除去には湿式法と乾式法がある。
湿式法は水又は薬剤を用いて洗浄し、蛍光物質を分離するものであるが、相当の水量を必要とし、洗浄後の排水による汚染の問題もあり、洗浄装置や回収装置等も高額であり、更に、発生汚泥（蛍光物質も含む）には水銀が高濃度で残留する。 Conventionally, for example, there are a wet method and a dry method for removing a fluorescent material containing mercury.
The wet method uses water or chemicals to separate the fluorescent substances, but requires a considerable amount of water, has a problem of contamination due to waste water after washing, and the cleaning and recovery equipment is expensive. Furthermore, mercury remains at a high concentration in the generated sludge (including fluorescent substances).

一方乾式法は両端が開口した蛍光灯切断面の内部に空気と固体粒子のプラグ流よりなるブラスト流を導入して付着している蛍光物質を剥離するもので、回転可能な筒状ドラム内に蛍光物質を剥離するブラシ体を設け、ブラシにより蛍光物質を掻き落とすもの、また、
回転可能な筒状ドラム内でガラス片を多量に滞留させガラス片同士がお互いに擦り合うことにより蛍光物質を掻き落とすものがある。
しかし、いずれの乾式法でも除去した蛍光剤等にも水銀含有量は高い濃度で残留しているのである。 The dry method, on the other hand, introduces a blast flow consisting of a plug flow of air and solid particles into the cut surface of a fluorescent lamp that is open at both ends, and peels off the adhering fluorescent material. A brush body that peels off the fluorescent material is provided, and the fluorescent material is scraped off by the brush,
Some glass pieces are retained in a rotatable cylindrical drum and the glass pieces are rubbed against each other to scrape off the fluorescent material.
However, the mercury content remains in a high concentration in the fluorescent agent and the like removed by any dry method.

また、連続処理のできないバッチ式では、100から200キログラムの処理に十数時間以上かかり、冷えるまで次の処理に移れず、真空ポンプの設備や窒素ガス置換等も必要となる。
そして、数段に重ねた容器で行うため攪拌が困難なことから内部までの加熱が充分にでき無いと共に、外部への水銀蒸気の放出が難しく、充分な除去能力を期待できないのである。 Moreover, in the batch type in which continuous processing cannot be performed, processing of 100 to 200 kilograms takes more than ten hours, and it is not possible to proceed to the next processing until it cools, and equipment for a vacuum pump and nitrogen gas replacement are required.
And since it is difficult to stir because it is carried out in several stacked containers, it is not possible to sufficiently heat the inside, and it is difficult to release mercury vapor to the outside, so that sufficient removal ability cannot be expected.

一方、コンベア移動式は設備が大きく、加熱設備も大きくなり加熱費用が増大するのに加え、攪拌が難しく内部まで加熱するためにはコンベアでの蛍光物質の移送量（厚み）を薄くする必要があり、その分処理効率が低下するのである。
特開２０００−２１５８１１号公報 特開２００２−２９４３５３号公報 On the other hand, the conveyor moving type has large equipment and large heating equipment, which increases heating costs. In addition, it is difficult to stir and it is necessary to reduce the transfer amount (thickness) of the fluorescent material on the conveyor in order to heat the inside. There is a corresponding reduction in processing efficiency.

そこで、本発明は小さなスペースで加熱接触面積が広く確保できると共に、攪拌も均質であり、しかも熱源も小さく効率的な乾式法による水銀含有物からの水銀分離回収装置の炉体の構造を提供せんとするものである。   Therefore, the present invention does not provide a furnace structure for a mercury separation and recovery apparatus from mercury-containing materials by an efficient dry method that can secure a wide heating contact area in a small space, is homogeneous in stirring, and has a small heat source. It is what.

本発明は、上部に水銀含有物供給口及び水銀蒸気排出口を有し、下部に水銀分離物回収口を設けた円筒状の炉体内を立設し、上下方向に複数段に分割し、分割した各空間の底となる仕切り板に落下孔を設けると共に、上下位置関係にあるに仕切り板の落下孔を異なる板面位置に配設し、円形の仕切り板面の中心を回転軸とし、仕切り板面上を摺擦する回転羽根を設けたことを特徴とする水銀含有物からの水銀分離回収装置における炉体の構造としたものである。   The present invention has a cylindrical furnace body having a mercury-containing material supply port and a mercury vapor discharge port in the upper part and a mercury separation product recovery port in the lower part, and is divided into a plurality of stages in the vertical direction. The partition plate that forms the bottom of each space is provided with a drop hole, the drop holes of the partition plate that are in a vertical position relationship are arranged at different plate surface positions, and the center of the circular partition plate surface is set as the rotation axis. A furnace body structure in a mercury separation / recovery device from mercury-containing material, characterized in that a rotary blade for rubbing on a plate surface is provided.

円筒状の炉体に上部供給口から入った水銀含有物は、分割された最上部の空間の仕切り板上に落ち、仕切り板や該空間の熱によって加熱され、水銀が蒸気となって分離するのであるが、仕切り板上に落下した水銀含有物は回転羽根で押されて転がったりしながら移動し、落下孔から下層の空間の仕切り板上に落ち、該空間でも同様に回転羽根によって移動させられ、更に下層の空間へ送られて行くるのである。
このように、円筒状の炉体ではあるけれど、各空間の仕切り板上を移動して行くので移動距離・時間が長く、回転羽根で転動したり、落下して攪拌され高熱の仕切り板との接触面が変ったりして均質な加熱となるものである。 Mercury-containing material that enters the cylindrical furnace body from the upper supply port falls on the partition plate in the uppermost divided space and is heated by the heat of the partition plate and the space, and mercury is separated as vapor. However, the mercury-containing material that has fallen on the partition plate moves while being rolled by being pushed by the rotating blades, falls from the dropping hole onto the partition plate in the lower space, and is similarly moved by the rotating blades in the space. It is sent to the space below.
In this way, although it is a cylindrical furnace body, it moves on the partition plates in each space, so the moving distance and time are long, and it rolls with rotating blades or falls and stirs and is heated and The contact surface changes, and the heating becomes homogeneous.

そして、上下位置関係にあるに仕切り板の落下孔を異なる板面位置に配設してあるから、下層の仕切り板で受け止められて該板上をさらに移動して行くのである。また、この落下孔を伝って加熱空気や水銀蒸気が上昇して行き上部の排出口へ自然に又は強制的に排出回収するものとなる。   Then, since the drop holes of the partition plate are arranged at different plate surface positions in the vertical position relationship, they are received by the lower partition plate and further moved on the plate. Further, the heated air or mercury vapor rises through the fall hole, and is discharged or collected naturally or forcibly to the upper discharge port.

請求項２の発明は、放射線状に複数個の回転羽根を回転軸に設けたことを特徴とするものであり、回転羽根が複数個あることによって、仕切り板上の水銀含有物を分けて移動させるものとなる。   The invention of claim 2 is characterized in that a plurality of rotating blades are provided radially on the rotating shaft, and the mercury-containing material on the partition plate is moved separately by the plurality of rotating blades. To be

請求項３の発明は、落下孔が円形の仕切り板面の中心部から炉の内周壁に至る溝状形であることを特徴とするものであり、仕切り板面上に拡散して回転羽根によって移動する水銀含有物は確実に落下孔から下段の仕切り板上に落下するものとなる。   The invention of claim 3 is characterized in that the drop hole has a groove shape extending from the center of the circular partition plate surface to the inner peripheral wall of the furnace, and is diffused on the partition plate surface by rotating blades. The moving mercury-containing material surely falls from the dropping hole onto the lower partition plate.

請求項４の発明は、水銀含有物供給口を、最上部に位置する仕切り板の落下孔の近傍で、回転羽根の回転方向の下流側に水銀含有物が落下するように設け、また、上下位置関係にある仕切り板では、上位置の落下孔に対して下位置の落下孔は、直下より回転羽根の回転方向の上流側近傍に設けたことを特徴とするものであり、供給口或いは上方の仕切り板の落下孔から落ちてくる水銀含有物は、更に次下層の仕切り板上へ送る落下孔までの移動距離を確実に得られるものとなる。   In the invention of claim 4, the mercury-containing material supply port is provided in the vicinity of the drop hole of the partition plate located at the uppermost part so that the mercury-containing material falls on the downstream side in the rotation direction of the rotary blades. In the partition plate in the positional relationship, the lower drop hole with respect to the upper drop hole is provided in the vicinity of the upstream side in the rotation direction of the rotary blade from directly below, and the supply port or the upper The mercury-containing material falling from the drop hole of the partition plate can surely obtain the moving distance to the drop hole to be fed onto the next lower partition plate.

請求項５の発明は、落下孔を複数個設けたことを特徴とするものであり、落下孔を各仕切り板に複数設けて下層への送りを早くすることができる。   The invention of claim 5 is characterized in that a plurality of dropping holes are provided, and a plurality of dropping holes are provided in each partition plate, so that the feeding to the lower layer can be accelerated.

本発明は小さな設置スペースでも複数段に亘って水銀含有物が運ばれ移動して行くものであるから、熱くなっている仕切り板との接触面が広く且つ時間も長く確保できるため、充分な熱を与えられて水銀蒸気となって分離する作用を促進させる効果を得られるものである。
そして、回転羽根に押されて運ばれ移動するものであるから転動し、下段への落下も伴い均質な加熱となる効果があり、強制的に攪拌をしないため蛍光剤等の発塵を防ぎ、後工程の除塵能力も小さいもので足り、除塵も容易となる効果を有する。
また、この落下孔を伝って加熱空気や水銀蒸気が上昇して行き上部の排出口へ自然に又は強制的に排出回収する効果をも有するものとなる。 Since the present invention is such that the mercury-containing material is carried and moved over a plurality of stages even in a small installation space, the contact surface with the heated partition plate can be secured widely and the time can be secured for a long time. The effect of accelerating the action of separating into mercury vapor can be obtained.
And since it is carried and moved by the rotating blades, it rolls and has the effect of heating uniformly with the fall to the lower stage, and it prevents dust generation of fluorescent agents etc. because it is not forcibly stirred. Also, it is sufficient that the dust removal capability in the post-process is small, and the dust removal is easy.
Further, the heated air or mercury vapor rises through this drop hole, and has an effect of discharging or collecting naturally or forcibly to the upper discharge port.

請求項２の発明は、回転羽根が複数個あることによって、仕切り板面上の水銀含有物を分けて運ぶものとなるため、各回転羽根の水銀含有物を運ぶ分担量が少量となり確実性が増す効果があり、また、仕切り板への供給量を増量することも可能となる。   In the invention of claim 2, since there are a plurality of rotating blades, the mercury-containing material on the partition plate surface is conveyed separately, so that the amount of the carrying of the mercury-containing material on each rotating blade is small and certainty is ensured. There is an effect of increasing, and it is also possible to increase the supply amount to the partition plate.

請求項３の発明は、回転羽根によって運ばれ移動する軌跡の幅に亘って落下孔を形成してあるため、水銀含有物を確実に下段へ落下させて送ることが出来る効果を有する。   The invention of claim 3 has the effect that the mercury-containing material can be reliably dropped and sent to the lower stage because the drop hole is formed over the width of the trajectory carried and moved by the rotary blade.

請求項４の発明は、水銀含有物供給口や上位置の仕切り板の落下孔から送られる水銀含有物が、送られる仕切り板の落下孔との関係では、回転羽根によって移動する方向の下流側近傍に落下するため、次の下層仕切り板に落下させる落下孔まで、その仕切り板上の移動軌道及び移動時間留まって加熱される効果を有するものである。   The invention of claim 4 is the downstream side in the direction in which the mercury-containing material sent from the mercury-containing material supply port or the drop hole of the upper partition plate moves by the rotary blade in relation to the drop hole of the partition plate to be sent. Since it falls in the vicinity, it has the effect of being heated by staying on the moving track and moving time on the partition plate up to the dropping hole to be dropped on the next lower partition plate.

請求項５の発明は、落下孔を各仕切り板に複数設けて必要な移動距離に合わせて短く設定することで処理効率を向上させる効果を発揮するものである。 The invention of claim 5 exhibits the effect of improving the processing efficiency by providing a plurality of drop holes in each partition plate and setting them to a short distance according to the required moving distance.

次に、本発明の実施の形態を図面に基づいて説明する。
図１は、本発明の一実施の形態を示す縦断正面図である。
１は炉体であり、上部に蛍光剤等の水銀含有物質を投入する供給口２が設けられ、残留槽３からスクリューコンベア４により適宜量を連続的に炉体１内へ供給し、また、上部には分離処理された水銀蒸気が排出される排出口５が設けてあり、排出パイプ６で連結する除塵機７、冷却器８を経て水銀回収槽９に水銀が回収される。
一方、炉体１の下端は水銀が分離処理された蛍光剤等の排出口１７となり、処理物回収槽１８が設けてある。 Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal front view showing an embodiment of the present invention.
1 is a furnace body, a supply port 2 for introducing a mercury-containing substance such as a fluorescent agent is provided at the upper part, and an appropriate amount is continuously supplied from the residual tank 3 to the furnace body 1 by a screw conveyor 4; The upper part is provided with a discharge port 5 through which the separated mercury vapor is discharged. Mercury is recovered in a mercury recovery tank 9 through a dust remover 7 and a cooler 8 connected by a discharge pipe 6.
On the other hand, the lower end of the furnace body 1 serves as a discharge port 17 for a fluorescent agent or the like from which mercury has been separated, and a treated product recovery tank 18 is provided.

炉体１は円筒状の箱体で、内部は上下方向に仕切り板１０、１０、１０・・・によって多数の空間に区分されている。
仕切り板１０及び炉体１は鋼材やステンレスで形成され溶接等で一体化し、炉体１の外周または仕切り板１０或いはその他炉体１に関連付けて適宜熱源による加熱手段（図示せず）を有し、炉体内の水銀含有物質から水銀蒸気となって水銀が分離する環境となっている。 The furnace body 1 is a cylindrical box body, and the inside is divided into a large number of spaces by partition plates 10, 10, 10,.
The partition plate 10 and the furnace body 1 are formed of steel or stainless steel and are integrated by welding or the like, and have a heating means (not shown) by an appropriate heat source associated with the outer periphery of the furnace body 1 or the partition plate 10 or other furnace body 1. In this environment, mercury is separated from mercury-containing materials in the furnace as mercury vapor.

そして、各仕切り板１０には落下孔１１が設けてあり、落下孔１１は、後述の仕切り板１０の中心に位置する回転軸１５用の挿通孔１２と炉体１の内周壁１３に亘る溝孔を成し、例えば円形である仕切り板１０の中心から２本の半径線で形成する扇形状に形成したものであってもよい。   Each partition plate 10 is provided with a drop hole 11, and the drop hole 11 is a groove extending between an insertion hole 12 for a rotating shaft 15 located at the center of a partition plate 10 described later and an inner peripheral wall 13 of the furnace body 1. The hole may be formed, for example, in a fan shape formed by two radial lines from the center of the circular partition plate 10.

また、各仕切り板１０の上面を摺擦する回転羽根１４が設置してあり、回転羽根１４は、高さを有する板状で、前述の仕切り板１０の挿通孔１２を貫通して吊設した回転軸１５に放射状に取り付けられ、先端は炉体１の内周壁１３に近接し回転軸１５の回転に伴って仕切り板１０上を周回するものである。
回転羽根１４は複数枚等間隔で設けるのがよく、各回転羽根１４，１４間の水銀含有物質を回転にともなって掻きながら運んで行くこととなり、回転羽根１４が多くなれば運ぶ分担量が少なくなってスムーズに且つ確実に運ぶことが出来る。 In addition, rotary blades 14 that rub the upper surface of each partition plate 10 are installed, and the rotary blades 14 are plate-like in height and are suspended through the insertion holes 12 of the partition plate 10 described above. The tip is attached radially to the rotating shaft 15, and the tip is close to the inner peripheral wall 13 of the furnace body 1 and circulates on the partition plate 10 as the rotating shaft 15 rotates.
The rotating blades 14 are preferably provided at equal intervals, and the mercury-containing material between the rotating blades 14 and 14 is carried while being scraped with the rotation. It can be smoothly and reliably carried.

仕切り板１０上を回転羽根１４によって運ばれ移動する水銀含有物質は、移動中に落下孔１１から落ち、下方の空間へ送られて下層の仕切り板１０上に落下し、落下した水銀含有物質は落ちた仕切り板１０上を、同様に回転羽根によって運ばれて移動し、形成された落下孔１１から更に下層空間の仕切り板１０へと送られるのである。
そして、仕切り板１０上を運ばれ移動する間に加熱され、水銀が水銀蒸気となって分離し上方の仕切り板１０の落下孔１１を通って排出口５から自然に又は強制的に発生させた上層気流によって排出されるのである。 The mercury-containing material that is carried and moved on the partition plate 10 by the rotary blades 14 falls from the drop hole 11 during the movement, is sent to the lower space, falls on the lower partition plate 10, and the mercury-containing material that has fallen is Similarly, the dropped partition plate 10 is carried and moved by the rotating blades, and is further sent from the formed drop hole 11 to the partition plate 10 in the lower space.
Then, it is heated while being transported on the partition plate 10, and the mercury is separated into mercury vapor and separated from the discharge port 5 through the drop hole 11 of the upper partition plate 10, either naturally or forcibly. It is discharged by the upper airflow.

そこで、水銀含有物供給口２又は上位置の仕切り板１０の落下孔１１から水銀含有物が落下するのであるが、図３は、落下する下層の仕切り板１０に形成された落下孔１１との関係を示し、上（供給口２又は上位置の仕切り板１０の落下孔１１）から下位置の仕切り板１０への落下位置（供給口の位置又は上位置の仕切り板１０の落下孔の位置でもある。）１６が、下位置の仕切り板１０の落下孔１１に対して回転羽根１４によって水銀含有物が移動する方向の下流側近傍としてある。
このような位置関係とすることで、水銀含有物は仕切り板１０上を略一周回って落下孔１１より更に下位置の仕切り板１０へ落下して行き、長い時間同一面上の加熱環境に水銀含有物を留めて水銀蒸気への分離作用を促進させることが出来るのである。 Therefore, the mercury-containing material falls from the mercury-containing material supply port 2 or the drop hole 11 of the upper partition plate 10, and FIG. 3 shows the relationship between the drop hole 11 formed in the falling lower partition plate 10. The relationship between the upper position (the supply port 2 or the drop hole 11 of the upper partition plate 10) and the lower position of the partition plate 10 (the position of the supply port or the position of the drop hole of the upper partition plate 10) 16) is in the vicinity of the downstream side in the direction in which the mercury-containing material moves by the rotary blade 14 with respect to the drop hole 11 of the partition plate 10 at the lower position.
By adopting such a positional relationship, the mercury-containing material goes around the partition plate 10 almost once and falls to the partition plate 10 located further below the drop hole 11, and the mercury remains in the heating environment on the same surface for a long time. The inclusions can be retained and the separation action into mercury vapor can be promoted.

図４は、仕切り板１０に落下孔１１を二つ形成したものであり、二つの落下孔１１，１１は円形の仕切り板１０の一直径上に形成し、上方のからの水銀含有物の落下位置１６，１６は各落下孔１１，１１に対して回転羽根１４によって水銀含有物が移動する方向の下流側近傍となっている。
落下孔１１をいくつ形成するかは、過熱環境、仕切り板で形成する空間の数、回転羽根の回転速度等によって、投入する水銀含有物の回転速度によって決まる。 FIG. 4 shows two drop holes 11 formed in the partition plate 10. The two drop holes 11, 11 are formed on one diameter of the circular partition plate 10 to drop the mercury-containing material from above. The positions 16 and 16 are near the downstream side in the direction in which the mercury-containing material moves by the rotary blades 14 with respect to the drop holes 11 and 11.
How many dropping holes 11 are formed depends on the rotational speed of the mercury-containing material to be introduced, depending on the superheated environment, the number of spaces formed by the partition plates, the rotational speed of the rotating blades, and the like.
