[0028] また、ウェス洗浄装置 100は、洗浄液剤中に溶解する蛍光塗料を除去し、且つ蛍 光塗料除去後の洗浄液剤を貯蔵するための洗浄液剤供給回収部 Bと、濯ぎ液剤中 に溶解する蛍光塗料を除去し、且つ蛍光塗料除去後の濯ぎ液剤を貯蔵するための 濯ぎ液剤供給回収部 Cと、ウェス洗浄機 A内に供給されるガスから、気化した洗浄液 剤又は濯ぎ液剤を回収するための排ガス分離部 Dを備える。  In addition, the waste cleaning apparatus 100 removes the fluorescent paint dissolved in the cleaning liquid, and also supplies the cleaning liquid supply / recovery part B for storing the cleaning liquid after removing the fluorescent paint, and dissolves in the rinsing liquid. The vaporized cleaning liquid or rinse liquid is recovered from the rinsing liquid supply / recovery unit C for removing the fluorescent paint to be stored and storing the rinsing liquid after the fluorescent paint is removed and the gas supplied to the waste washer A. An exhaust gas separator D is provided.
[0029] 図 2は、ウェス洗浄機 Aの構成を拡大して模式的に示す説明図である。  FIG. 2 is an explanatory diagram schematically showing an enlarged configuration of the waste washer A. As shown in FIG.
図 2に示すように、ウェス洗浄機 Aは洗浄の対象となるウェスを洗浄し濯ぎ且つ乾 燥することができるもので、内部の温度を適宜自由に調節することも可能である。 また、ウェス洗净機 Aは内部のエアーゃ洗净液、或いは濯ぎ液等を供給又は排出 する流路を有する。  As shown in FIG. 2, the waste washer A can wash, rinse and dry the waste to be cleaned, and the internal temperature can be freely adjusted as appropriate. In addition, the waste washer A has a flow path for supplying or discharging an internal air cleaning solution or a rinsing solution.
ウェス洗浄機 Aは、円筒状の密閉した空間を有する洗浄機本体 A1と、洗浄液剤及 び濯ぎ液剤を貯留するための洗浄タンク A2と、液剤供給ノズル A3と、ガス供給口 A 4と、ガス排出口 A5と、を備える。  The waste washer A includes a washer main body A1 having a cylindrical sealed space, a washing tank A2 for storing a washing liquid and a rinsing liquid, a liquid supply nozzle A3, a gas supply port A4, a gas And an outlet A5.
さらに、長尺反物状のウェス Xを洗浄液剤及び濯ぎ液剤に浸漬させながら、巻き取 るための第 1のリール alと第 2のリール a2とを備える。  Furthermore, a first reel al and a second reel a2 are provided for winding the long cloth-shaped waste cloth X while it is immersed in the cleaning liquid and the rinsing liquid.
ここでウェスとは、例えば、天然繊維、合成繊維、半合成繊維等よりなる編地布、織 地布、不織布等であり、また合成樹脂等よりなる榭脂フィルムであり、何れも蛍光塗料 が含まれて 、るものである。 Here, the waste is, for example, a knitted fabric, a woven fabric, a non-woven fabric or the like made of natural fiber, synthetic fiber, semi-synthetic fiber, or the like, or a resin film made of synthetic resin or the like. Is included.
[0030] 液剤供給ノズル A3は、後述する洗浄液剤投入タンク 6に貯蔵されている洗浄液剤 を、洗浄タンク A2に供給する際に、第 1のリール alと第 2のリール a2間を往復移動す るウェス Xの幅全体に対して高圧(例えば、吹き出し圧が、 0. 15MPa)で噴射しなが ら供給する。  [0030] The liquid supply nozzle A3 reciprocates between the first reel al and the second reel a2 when supplying the cleaning liquid stored in the cleaning liquid charging tank 6 described later to the cleaning tank A2. Supplied while being injected at a high pressure (for example, a blowout pressure of 0.15 MPa) over the entire width of Wess X.
洗浄液剤を高圧でウェス Xに対して噴射することで、その圧力でウェス Xに強固に 付着する蛍光塗料が除去され易い状態となるので、洗浄工程における洗浄効果を向 上させることができる。  By spraying the cleaning liquid onto the waste cloth X at a high pressure, the fluorescent paint that adheres firmly to the waste cloth X is easily removed by the pressure, so that the washing effect in the washing process can be improved.
[0031] また、液剤供給ノズル A3は、後述する濯ぎ液剤貯蔵タンク 9に貯蔵されて ヽる濯ぎ 液剤を、洗浄タンク A2に供給する際にも同様にウェス Xの幅全体に対して高圧で噴 射しながら供給することで濯ぎ工程における濯ぎ効果を向上させる。  [0031] In addition, the liquid supply nozzle A3 sprays the rinsing liquid stored in a rinsing liquid storage tank 9 (described later) at a high pressure on the entire width of the waste X when supplying the cleaning liquid A2 to the cleaning tank A2. By supplying while spraying, the rinsing effect in the rinsing process is improved.
[0032] ガス供給口 A4は後述するように、例えば洗浄工程前に爆発防止用の不燃性ガス を、洗浄機本体 A1内に供給するため等に使用される供給口である。  [0032] As will be described later, the gas supply port A4 is a supply port used for supplying, for example, an incombustible gas for preventing explosion into the cleaning machine main body A1 before the cleaning process.
ガス排出口 A5は、ウェス洗浄機 A内に充満する混合ガスを、ウェス洗浄機 A外に 排出するための排出口である。  The gas discharge port A5 is an exhaust port for discharging the mixed gas filling the waste washer A to the outside of the waste washer A.
なお、混合ガスとは空気、不燃性ガス、気化した洗浄液剤、気化した濯ぎ液剤等が 混ざった状態の気体をいう。  The mixed gas refers to a gas in which air, non-combustible gas, vaporized cleaning liquid, vaporized rinsing liquid, etc. are mixed.
[0033] 第 1のリール alと第 2のリール a2は洗浄タンク A2の上方に、一定距離隔てた状態 で取り付けられる。  [0033] The first reel al and the second reel a2 are mounted above the cleaning tank A2 at a predetermined distance.
第 1のリール alは、第 2のリール a2に巻き取られているウェス Xを洗浄タンク A2内 に配置される案内ローラー a3を介して、該洗浄タンク A2に貯留される洗浄液又は濯 ぎ液に浸漬させながら巻き取る機能を持つ。  The first reel al passes the waste cloth X wound around the second reel a2 into the cleaning liquid or the rinsing liquid stored in the cleaning tank A2 via the guide roller a3 disposed in the cleaning tank A2. It has the function of winding while immersed.
[0034] そして、第 2のリール a2も第 1のリール alと同様に、第 1のリール alに巻き取られた ウェス Xを、案内ローラー a3を介して、洗浄タンク A2の液剤に浸漬させながら巻き取 る機能を持つ。 [0034] Then, in the same manner as the first reel al, the second reel a2 is also immersed in the liquid agent in the cleaning tank A2 through the guide roller a3 while the waste cloth X wound around the first reel al is immersed in the solution. It has a winding function.
[0035] なお、案内ローラー a3を配置する位置やその数等はウェス Xを洗浄液剤又は濯ぎ 液剤に確実に浸漬させることができるのであれば、その位置やその数は自由に適宜 選択することができることは当然である。 [0036] ところで、ウェス洗浄機 Aは液剤循環部 Rを備える。 [0035] It should be noted that the position and the number of the guide rollers a3 are appropriately selected as long as the cloth X can be surely immersed in the cleaning liquid or the rinsing liquid. It is natural that we can do it. By the way, the waste washer A includes a liquid agent circulation section R.
液剤循環部 Rは洗浄タンク A2内の洗浄液剤又は濯ぎ液剤を循環させる機能を有 する。  The liquid circulation part R has a function of circulating the cleaning liquid or the rinsing liquid in the cleaning tank A2.
そして液剤循環部 Rは洗浄タンク A2から排出された洗浄液剤又は濯ぎ液剤を強制 的に循環移動させるためのポンプ R1を備え、該ポンプ R1は液剤供給ノズル A3と接 続されている。  The liquid circulation section R includes a pump R1 for forcibly circulating and moving the cleaning liquid or the rinsing liquid discharged from the cleaning tank A2, and the pump R1 is connected to the liquid supply nozzle A3.
[0037] ポンプ R1によって洗浄タンク A2内の洗浄液剤又は濯ぎ液剤は洗浄タンク A2外に ー且排出され、その排出された洗浄液剤又は濯ぎ液剤は、液剤供給ノズル A3から ある一定の圧力で、ウェス Xに向カゝつて噴射されて、洗浄タンク A2内へ戻される。  [0037] The cleaning liquid or rinsing liquid in the cleaning tank A2 is discharged and discharged from the cleaning tank A2 by the pump R1, and the discharged cleaning liquid or rinsing liquid is washed at a certain pressure from the liquid supply nozzle A3. It is injected toward X and returned to cleaning tank A2.
[0038] 後述する洗浄工程中、又は後述する濯ぎ工程中に、常時、液剤循環部を作動させ ることで、蛍光塗料が洗浄タンク A2内に堆積又は付着するのを抑制することができる すなわち、蛍光塗料を液剤に極力溶解した状態にして、洗浄タンク A2から排出す ることが可能になる。  [0038] By always operating the liquid agent circulation unit during the cleaning step described later or the rinsing step described later, it is possible to suppress the fluorescent paint from being deposited or adhered in the cleaning tank A2. It becomes possible to discharge the fluorescent paint from the cleaning tank A2 in a state where it is dissolved in the liquid as much as possible.
[0039] さらに、液剤供給ノズル A3から、洗浄液剤又は濯ぎ液剤を一定の圧力でウェスに 向かって噴射することにより、その液剤の圧力でウェスに強固に付着する蛍光塗料を 強制的に除去することも可能である。  [0039] Further, by spraying the cleaning liquid or the rinsing liquid from the liquid supply nozzle A3 toward the waste at a constant pressure, the fluorescent paint that adheres firmly to the waste at the pressure of the liquid is forcibly removed. Is also possible.
その結果、洗浄効果や濯ぎ効果が向上する。  As a result, the cleaning effect and the rinsing effect are improved.
[0040] 〔洗浄液剤供給回収部〕 [0040] [Cleaning liquid supply / recovery section]
洗浄液剤供給回収部 Bは、蛍光塗料が溶解する洗浄液剤から蛍光塗料を除去し、 再利用可能な状態にして回収する。  The cleaning liquid supply / recovery unit B removes the fluorescent paint from the cleaning liquid in which the fluorescent paint dissolves and collects it in a reusable state.
図 1に示すように、洗浄液剤供給回収部 Bは、具体的に、洗浄液剤用バッファータ ンク 3と、洗浄液剤用蛍光塗料除去部 4と、洗浄液剤貯蔵タンク 5と、洗浄液剤投入タ ンク 6と、を備える。  As shown in FIG. 1, the cleaning liquid supply / recovery unit B specifically includes a cleaning liquid buffer tank 3, a cleaning liquid fluorescent paint removing unit 4, a cleaning liquid storage tank 5, and a cleaning liquid charging tank. And 6.
[0041] 洗浄液剤用蛍光塗料除去部 4は、洗浄タンク A2から排出される洗浄液剤から該洗 浄液剤中に溶解する蛍光塗料を除去し、洗浄液剤を再利用可能にする機能を有す る。  [0041] The fluorescent paint removing unit 4 for the cleaning liquid agent has a function of removing the fluorescent paint dissolved in the cleaning liquid agent from the cleaning liquid discharged from the cleaning tank A2, and making the cleaning liquid reusable. .
[0042] 洗浄液剤用蛍光塗料除去部 4で採用される主な蛍光塗料の除去手段としては、図 1に示すように、ろ過用のフィルター Fを通過させることで行われる。 [0042] As a main fluorescent paint removing means employed in the fluorescent paint removing unit 4 for cleaning liquid, FIG. As shown in 1, it is performed by passing the filter F for filtration.
[0043] そして、ろ過用のフィルター Fはメッシュ目の粗さを異にするものを複数個備えること でより、無理なく確実な蛍光塗料の回収効率を発揮できる。 [0043] By providing a plurality of filters F having different mesh sizes, the filtration efficiency of the fluorescent paint can be exerted without difficulty.
ここでは、図 1に示すように、最初に 3 のメッシュ目を有する第 1フィルター F1と、 次に第 1フィルター F1より細力ぃ1 μのメッシュ目を有する第 2フィルター F2とを備え ている。  Here, as shown in FIG. 1, the first filter F1 having a mesh of 3 at the beginning and the second filter F2 having a mesh of 1 μm stronger than that of the first filter F1 are provided. .
このように第 1フィルター F1及び第 2フィルター F2の 2段のフィルターを備えることに より、第 1段目の第 1フィルター F1の負担を少なくでき、且つ第 2段目の第 2フィルタ 一 F2によって更に細かい濾取ができ、蛍光塗料の全体として回収が無理なく効率良 く行われる。  By providing a two-stage filter of the first filter F1 and the second filter F2 in this way, the burden on the first filter F1 of the first stage can be reduced, and the second filter of the second stage F1 Finer filtration can be achieved, and the entire fluorescent paint can be recovered efficiently and efficiently.
[0044] 本実施形態に係るウェス洗浄装置 100には、除去対象となる蛍光塗料の種類毎に 蛍光塗料を回収するために、洗浄液剤供給回収部 Βには洗浄液剤用蛍光塗料除去 部 4が複数系統備えられて 、る。  In the waste cleaning apparatus 100 according to the present embodiment, a cleaning liquid supply / collection unit has a cleaning liquid fluorescent paint removal unit 4 in order to collect the fluorescent paint for each type of fluorescent paint to be removed. Multiple systems are provided.
この結果、同種類の蛍光塗料だけを効率的に一箇所に集めることができ、蛍光塗 料回収後に行う種々の作業を円滑に行うことができるようになる。  As a result, only the same type of fluorescent paint can be efficiently collected in one place, and various operations performed after the fluorescent paint is collected can be smoothly performed.
[0045] 例えば、本実施形態に係るウェス洗浄装置 100において、赤色系の発光を行う赤 色蛍光塗料が付着したウェスを洗浄した場合は、赤色蛍光塗料を除去するための洗 浄液剤用蛍光塗料除去部 41に洗浄液剤を通過させる。 [0045] For example, in the waste cleaning apparatus 100 according to the present embodiment, when the waste with the red fluorescent paint that emits red light is washed, the fluorescent paint for the cleaning liquid for removing the red fluorescent paint is used. The cleaning liquid is passed through the removal unit 41.
また、緑色系の発光を行う緑色蛍光塗料が付着したウェスを洗浄した場合は、緑色 蛍光塗料を除去するための洗浄液剤用蛍光塗料除去部 42に洗浄液剤を通過させ る。  Further, when the waste with the green fluorescent paint that emits green light is washed, the cleaning liquid is passed through the fluorescent paint removing unit 42 for the cleaning liquid for removing the green fluorescent paint.
或!、はまた、青色系の発光を行う青色蛍光塗料が付着したウェスを洗浄した場合 は、青色蛍光塗料を除去するための洗浄液剤用蛍光塗料除去部 43に洗浄液剤を 通過させる。  Or, when the waste with the blue fluorescent paint that emits blue light is washed, the cleaning liquid is passed through the fluorescent paint removing unit 43 for cleaning liquid for removing the blue fluorescent paint.
以上のように、洗浄対象のウェスに付着する蛍光塗料の種類に応じて、洗浄液剤 の排出先の洗浄液剤用蛍光塗料除去部を変えることで、赤色蛍光塗料、緑色蛍光 塗料、青色蛍光塗料をそれぞれ選別して別個に回収することができる。  As described above, red fluorescent paint, green fluorescent paint, and blue fluorescent paint can be changed by changing the fluorescent paint removal section for the cleaning liquid discharge destination according to the type of fluorescent paint that adheres to the waste to be cleaned. Each can be sorted and collected separately.
[0046] 洗浄液剤用バッファータンク 3は、洗浄液剤用蛍光塗料除去部 4の上流位置に配 置されており、洗浄タンク A2から排出された洗浄液剤が滞留するのを防ぐ機能を持 つ。 [0046] The cleaning liquid buffer tank 3 is arranged upstream of the cleaning liquid fluorescent paint removing section 4. It has a function to prevent the cleaning liquid discharged from cleaning tank A2 from accumulating.
[0047] すなわち、洗浄液剤用蛍光塗料除去部 4に何らかの障害が発生し、洗浄タンク A2 カゝら排出される洗浄液剤の排出速度と、蛍光塗料除去部 4で行われる蛍光塗料の除 去速度に差が発生した場合に、一時的に洗浄液剤を洗浄液剤用バッファータンク 3 に受け入れることで、洗浄液剤が洗浄タンク A2に滞留することを防止する。  [0047] That is, when a failure occurs in the fluorescent paint removal unit 4 for the cleaning liquid, the discharge rate of the cleaning liquid discharged from the cleaning tank A2 and the removal rate of the fluorescent paint performed in the fluorescent paint removal unit 4 If a difference occurs, the cleaning liquid is temporarily received in the cleaning liquid buffer tank 3 to prevent the cleaning liquid from staying in the cleaning tank A2.
[0048] そして、洗浄液剤用蛍光塗料除去部 4において、万が一完全に蛍光塗料の除去が 行われなくなった場合であっても、洗浄液剤の滞留を防ぐために、洗浄液剤用バッフ ァータンク 3の容積は洗浄タンク A2の容積よりも大き 、ことが好ま 、。  [0048] Then, even if the fluorescent paint removal unit 4 for the cleaning liquid does not completely remove the fluorescent paint, the volume of the buffer tank 3 for the cleaning liquid is set to prevent the cleaning liquid from staying. It is preferred that it is larger than the volume of the washing tank A2.
[0049] また、洗浄液剤用バッファータンク 3と蛍光塗料除去部 4との間には、洗浄液剤の一 部を再び洗浄液剤用バッファータンク 3に戻す経路 31が備えられており、この経路を 備えることで、洗浄液剤が循環し、洗浄液剤用バッファータンク 3内に蛍光塗料が沈 殿することを防止する。  [0049] In addition, a path 31 is provided between the cleaning liquid buffer tank 3 and the fluorescent paint removing unit 4 to return a part of the cleaning liquid to the cleaning liquid buffer tank 3 again. As a result, the cleaning liquid circulates and the fluorescent paint is prevented from being deposited in the buffer tank 3 for the cleaning liquid.
[0050] 洗浄液剤貯蔵タンク 5は、排ガス分離部 Dと接続されており、排ガス分離部 Dで回 収された洗浄液剤又は濯ぎ液剤をここで一旦貯蔵して洗浄液剤用蛍光体除去部 4 力 の洗浄液剤と一緒にし、その後、洗浄液剤投入タンク 6に送る機能を有する。  [0050] The cleaning liquid storage tank 5 is connected to the exhaust gas separation unit D. The cleaning liquid or the rinsing liquid collected by the exhaust gas separation unit D is temporarily stored here, and the phosphor removal unit for cleaning liquid 4 It has the function of being sent together with the cleaning liquid and then sent to the cleaning liquid tank 6.
[0051] 洗浄液剤投入タンク 6は、洗浄液剤用蛍光体除去部 4において蛍光塗料が除去さ れた再利用可能になった洗浄液剤が、洗浄タンク A2に供給されるまでの間、貯蔵さ れる部分である。  [0051] The cleaning liquid charging tank 6 is stored until the cleaning liquid that can be reused after the fluorescent paint is removed in the cleaning liquid phosphor removing section 4 is supplied to the cleaning tank A2. Part.
[0052] また、洗浄液剤投入タンク 6には後述する液剤調整タンク 20が接続されている。  Further, a liquid agent adjustment tank 20 described later is connected to the cleaning liquid agent supply tank 6.
液剤調整タンク 20は、洗浄液剤が洗浄タンク A2から排出されて、洗浄液剤投入タ ンク 6に貯蔵されるまでの過程で、洗浄液剤の成分比率に変化が生じた場合に、洗 浄液剤の成分比率を適正に戻す機能を有する。  The liquid adjustment tank 20 is a component of the cleaning liquid when the ratio of the cleaning liquid changes in the process from the time when the cleaning liquid is discharged from the cleaning tank A2 and stored in the cleaning liquid charging tank 6. Has a function to return the ratio to an appropriate level.
すなわち、液剤調整タンク 20の内部には調整された洗浄液剤が貯蔵されており、 その洗浄液剤を状況に応じて適宜洗浄液剤投入タンク 6に送り込むことで、洗浄液 剤投入タンク 6内の洗浄液剤を常に適正な成分比率に保っている。  That is, the adjusted cleaning liquid is stored inside the liquid adjustment tank 20, and the cleaning liquid in the cleaning liquid input tank 6 is supplied by appropriately sending the cleaning liquid to the cleaning liquid input tank 6 according to the situation. Always keep the proper component ratio.
ここで、通常、洗浄液剤としては、主としてメタノールの他、酢酸、リモネン等の添カロ 剤が含有されており、この洗浄液剤投入タンク 6にて洗浄液剤が適切に調整される。 [0053] 〔洗浄液剤の回収サイクル〕 Here, the cleaning liquid usually contains, in addition to methanol, additive agents such as acetic acid and limonene, and the cleaning liquid is appropriately adjusted in the cleaning liquid charging tank 6. [Recovery cycle of cleaning liquid]
次に、洗浄工程において使われた使用済の洗浄液剤が、再利用可能となって再び 洗浄タンク内に供給されるまでの過程を説明する。  Next, the process until the used cleaning liquid used in the cleaning process becomes reusable and is supplied to the cleaning tank again will be described.
まず、ウェス洗浄機 A内で洗浄工程が完了すると、洗浄タンク A2から使用された洗 浄液剤が排出され、洗浄液剤用バッファータンク 3を通過して洗浄液剤用蛍光塗料 除去部 4に送られる。  First, when the cleaning process is completed in the waste washer A, the used cleaning solution is discharged from the cleaning tank A2, passes through the cleaning solution buffer tank 3, and is sent to the cleaning solution fluorescent paint removing unit 4.
[0054] このとき、洗浄工程において洗浄したウェスに付着した蛍光塗料の種類に応じて、 洗浄液剤用バッファータンク 3の前に設けられて閉じていたノ レブが適宜開かれる。 すなわち、本実施形態に係るウェス洗浄装置 100においては、赤色系の蛍光塗料 が洗浄液剤に含まれている場合は、バルブ VIのみを開放して、赤色系蛍光塗料の 除去を行う蛍光塗料回収部 41にのみ洗浄液剤が流れるようにする。  [0054] At this time, the closed nozzle provided in front of the cleaning liquid buffer tank 3 is appropriately opened according to the type of fluorescent paint adhering to the waste washed in the washing step. That is, in the waste washing apparatus 100 according to the present embodiment, when the red fluorescent paint is contained in the cleaning liquid, only the valve VI is opened and the red fluorescent paint collecting unit is removed to remove the red fluorescent paint. Allow cleaning fluid to flow only in 41.
また例えば、洗浄液剤中の緑色系蛍光塗料を除去する場合にはバルブ V2のみを 開放し、或いは洗浄液剤中の青色系蛍光塗料を除去する場合には、バルブ V3のみ を開放するというように、洗浄液剤が特定の蛍光塗料回収部のみ通過するようにバル ブが選択的に開放される。  In addition, for example, when removing the green fluorescent paint in the cleaning liquid, only the valve V2 is opened, or when removing the blue fluorescent paint in the cleaning liquid, only the valve V3 is opened. The valve is selectively opened so that the cleaning liquid passes only through the specific fluorescent paint recovery section.
このように除去する蛍光塗料の種類に応じてバルブを選択的に開閉することで、効 率的な蛍光塗料の回収が可能となる。  By selectively opening and closing the valve according to the type of fluorescent paint to be removed in this way, it is possible to efficiently collect the fluorescent paint.
[0055] そして、洗浄液剤用蛍光体除去部 4に送られた洗浄液剤は、ろ過用の第 1フィルタ 一 Fl、ろ過用の第 2フィルター F2を順次通過する過程で、効率的に洗浄液剤の蛍 光塗料がろ過されて分離回収される。 [0055] Then, the cleaning liquid sent to the cleaning liquid phosphor removing section 4 passes through the first filter for filtration Fl and the second filter for filtration F2 in order, and the cleaning liquid agent is efficiently removed. The fluorescent paint is filtered and separated.
[0056] 蛍光塗料が除去された洗浄液剤は、洗浄液剤貯蔵タンク 5に一旦貯蔵される。 The cleaning liquid from which the fluorescent paint has been removed is temporarily stored in the cleaning liquid storage tank 5.
そして、洗浄液剤貯蔵タンク 5に貯蔵された洗浄液剤は、排ガス分離部 Dで回収さ れた洗浄液剤と共に洗浄液剤投入タンク6に送られる。 Then, the cleaning liquid stored in the cleaning liquid storage tank 5 is sent to the cleaning liquid charging tank 6 together with the cleaning liquid recovered by the exhaust gas separation unit D.
[0057] 洗浄液剤投入タンク 6に洗浄液剤が送られると、先述したように、洗浄液剤の成分 比率を適正な値に戻すために、液剤調整タンク 20から調整された洗浄液剤が洗浄 液剤投入タンク 6に注入される。 [0057] When the cleaning liquid is sent to the cleaning liquid charging tank 6, as described above, the cleaning liquid adjusted from the liquid adjusting tank 20 is used as the cleaning liquid charging tank in order to return the component ratio of the cleaning liquid to an appropriate value. Injected into 6.
より、具体的には、液剤調整タンク 20には洗浄液剤の主成分の液剤が貯蔵されて V、る液剤タンク 21と、洗浄液剤の主成分となる液剤に添加されるその他の薬剤が貯 蔵されている添加薬剤貯蔵タンク 22とが接続されており、液剤調整タンク 20は成分 比率が調整された洗浄液剤の貯蔵を行う。 More specifically, the liquid preparation tank 20 stores the main liquid of the cleaning liquid V, and the liquid tank 21 and other chemicals added to the main liquid of the cleaning liquid are stored. It is connected to the stored additive medicine storage tank 22, and the liquid preparation tank 20 stores the cleaning liquid whose component ratio is adjusted.
洗浄液剤投入タンク 6内の洗浄液剤の成分比率が適正でな 、場合、液剤調整タン ク 20から調整された洗浄液剤が洗浄液剤投入タンク 6内に送り込まれ、洗浄液剤投 入タンク 6内の洗浄液剤が適正な成分比率に調整される。  If the component ratio of the cleaning liquid in the cleaning liquid charging tank 6 is not appropriate, the cleaning liquid adjusted from the liquid adjusting tank 20 is sent into the cleaning liquid charging tank 6 and the cleaning liquid in the cleaning liquid charging tank 6 is used. The agent is adjusted to an appropriate component ratio.
そして、適正な成分比率になった洗浄液剤は洗浄タンク A2に注入されるまでの間 、洗净液剤投入タンク 6に貯蔵される。  The cleaning liquid having an appropriate component ratio is stored in the cleaning liquid charging tank 6 until it is injected into the cleaning tank A2.
[0058] 洗浄液剤が洗浄タンクに供給される場合、洗浄液剤投入タンク 6から送られた洗浄 液剤は液剤供給ノズル A3から一定圧力でウェスに対して噴射されながら貯留される [0058] When the cleaning liquid is supplied to the cleaning tank, the cleaning liquid sent from the cleaning liquid charging tank 6 is stored while being injected from the liquid supply nozzle A3 to the waste at a constant pressure.
[0059] 〔濯ぎ液剤供給回収部〕 [0059] [Rinse Solution Supply / Recovery Unit]
図 1に示すように、濯ぎ液剤供給回収部 Cは、濯ぎ工程で使用した濯ぎ液剤力 蛍 光塗料を除去し、蛍光塗料除去済みの濯ぎ液剤を貯蔵する機能を有する。  As shown in FIG. 1, the rinsing liquid supply / recovery unit C has a function of removing the rinsing liquid power fluorescent paint used in the rinsing process and storing the rinse liquid after the fluorescent paint is removed.
濯ぎ液剤供給回収部 Cは、濯ぎ液剤用バッファータンク 7と、濯ぎ液剤用蛍光塗料 除去部 8と、濯ぎ液剤貯蔵タンク 9と、を備える。  The rinsing liquid supply / recovery unit C includes a rinsing liquid buffer tank 7, a rinsing liquid fluorescent paint removing unit 8, and a rinsing liquid storage tank 9.
これらのうち、濯ぎ液剤用蛍光塗料除去部 8で、濯ぎ工程で使用された使用済みの 濯ぎ液剤から、該濯ぎ液剤に溶解する蛍光塗料が除去される。  Among these, the fluorescent paint removing unit 8 for rinsing liquid removes the fluorescent paint dissolved in the rinsing liquid from the used rinsing liquid used in the rinsing step.
[0060] 濯ぎ液剤用蛍光塗料除去部 8における蛍光塗料の除去方法は、洗浄液剤用蛍光 塗料除去部 4と同様に、ろ過用のフィルター Fを用いる方法が主に採用される。 [0060] As with the fluorescent paint removing unit 4 for the cleaning liquid, a method using the filter F for filtration is mainly employed as the fluorescent paint removing method in the fluorescent paint removing unit 8 for the rinsing liquid.
[0061] この場合も、メッシュ目の異なる複数のろ過用のフィルター Fl、 F2、 F3を備えること で、蛍光塗料の回収効率を向上させることが可能となる。 [0061] Also in this case, the collection efficiency of the fluorescent paint can be improved by providing a plurality of filtration filters Fl, F2, and F3 having different meshes.
[0062] また、濯ぎ液剤供給回収部 Cは、先述した洗浄液剤供給回収部 Bと同様に、濯ぎ液 剤用蛍光塗料除去部 8を、除去すべき蛍光塗料の種類に応じて複数系統備えること で、濯ぎ液剤から蛍光塗料を効率的に回収することが可能となる。 [0062] In addition, the rinsing liquid supply / recovery unit C includes a plurality of rinsing liquid fluorescent paint removing units 8 depending on the type of fluorescent paint to be removed, in the same manner as the cleaning liquid supply / recovery unit B described above. Thus, the fluorescent paint can be efficiently recovered from the rinse liquid.
[0063] 濯ぎ液剤用バッファータンク 7は、濯ぎ液剤用蛍光塗料除去部 8の上流位置に配置 され、濯ぎ液剤が滞留するのを防ぐ機能を有する。 [0063] The rinsing liquid buffer tank 7 is disposed upstream of the rinsing liquid fluorescent paint removing unit 8 and has a function of preventing the rinsing liquid from staying.
すなわち、濯ぎ液剤用蛍光塗料除去部 8に何らかの障害が発生し、濯ぎ液剤の排 出速度と、濯ぎ液材用蛍光塗料除去部 7での蛍光塗料除去速度に差が発生した場 合に、濯ぎ液剤用バッファータンク 7が一時的に濯ぎ液剤を受け入れることで、濯ぎ 液剤が洗浄タンク A2に滞留することを防止する。 In other words, when a failure occurs in the rinsing liquid fluorescent paint removing unit 8 and there is a difference between the rinsing liquid discharging speed and the fluorescent paint removing speed in the rinsing liquid fluorescent paint removing unit 7. In addition, the rinsing liquid buffer tank 7 temporarily receives the rinsing liquid, thereby preventing the rinsing liquid from staying in the cleaning tank A2.
[0064] また、濯ぎ液剤用蛍光塗料除去部 8において万が一完全に蛍光塗料の除去が行 われなくなった場合であっても、濯ぎ液剤の滞留を防ぐために、濯ぎ液剤用バッファ 一タンク 7の容積は洗浄タンク A2の容積よりも大き 、ことが好ま U、。 [0064] In addition, even if the fluorescent paint removal unit 8 for the rinsing liquid agent does not completely remove the fluorescent paint, the volume of the rinsing liquid buffer tank 7 is set to prevent the rinsing liquid agent from staying. U, which is larger than the volume of the washing tank A2.
[0065] 濯ぎ液剤貯蔵タンク 9は、濯ぎ液剤用蛍光塗料除去部 8で蛍光塗料が除去され、 再利用可能になった濯ぎ液剤を、洗浄タンク A2内に供給するまでの間、一時的に貯 蔵する場所である。 [0065] The rinsing liquid storage tank 9 temporarily stores the rinsing liquid after the fluorescent paint has been removed by the rinsing liquid fluorescent paint removing unit 8 until the reusable rinsing liquid is supplied into the cleaning tank A2. It is a place to store.
また、濯ぎ液剤貯蔵タンク 9は、液剤調整タンク 20を介して洗浄液剤投入タンク 6と 接続されており、緊急時には濯ぎ液剤を、濯ぎ液剤貯蔵タンク 9から洗浄液剤投入タ ンク 6に送る役割を果たす。  Further, the rinsing liquid storage tank 9 is connected to the cleaning liquid supply tank 6 via the liquid adjustment tank 20, and plays a role of sending the rinsing liquid from the rinsing liquid storage tank 9 to the cleaning liquid input tank 6 in an emergency. .
すなわち、洗浄液剤投入タンク 6内に洗浄工程に必要とされる量の洗浄液剤が無く 、且つ液剤調整タンク 20と液剤タンク 21にも十分な量の洗浄液剤が無い場合、緊急 措置として濯ぎ液剤貯蔵タンク 9内の濯ぎ液剤が一度液剤調整タンク 20に送られ、 そこで洗浄液剤の成分比率に調整されてから洗浄液剤投入タンク 6に送られる。  That is, if there is no cleaning liquid in the cleaning liquid supply tank 6 required for the cleaning process, and there is not a sufficient amount of cleaning liquid in the liquid adjustment tank 20 and the liquid tank 21, the rinsing liquid is stored as an emergency measure. The rinsing liquid in the tank 9 is once sent to the liquid preparation tank 20, where it is adjusted to the component ratio of the cleaning liquid and then sent to the cleaning liquid charging tank 6.
[0066] 〔濯ぎ液剤の回収サイクル〕 [0066] [Rinsing liquid recovery cycle]
次に、濯ぎ工程において使われた使用済みの濯ぎ液剤が再利用可能となり、再び 洗浄タンク A2内に供給されるまでの流れを説明する。  Next, a flow until the used rinsing liquid used in the rinsing process becomes reusable and is supplied again into the washing tank A2 will be described.
まず濯ぎ工程が完了すると、洗浄タンク A2から使用済みの濯ぎ液剤が排出され、 濯ぎ液剤用バッファータンク 7を通過して、濯ぎ液剤用蛍光塗料除去部 8に送られる  First, when the rinsing process is completed, the used rinsing liquid is discharged from the washing tank A2, passes through the rinsing liquid buffer tank 7, and is sent to the rinsing liquid fluorescent paint removing unit 8.
[0067] この濯ぎ液剤用蛍光塗料除去部 8に送られた使用済みの濯ぎ液剤は、ここで蛍光 塗料を除去され、再利用可能な状態となって濯ぎ液剤貯蔵タンク 9に貯蔵される。 この蛍光塗料の除去には、前述したように、 3 μのメッシュ目を有する第 1フィルター F1, 1 μのメッシュ目を有する第 2フィルター F2、 0. 5 μのメッシュ目を有する第 3フィ ルター F3を順次通過させることにより、蛍光塗料の全体として回収が無理なく効率良 く行われる。 [0067] The used rinsing liquid sent to the rinsing liquid fluorescent paint removing unit 8 is stored in the rinsing liquid storage tank 9 in a state where it can be reused after the fluorescent paint is removed. To remove the fluorescent paint, as described above, the first filter F3 having a mesh size of 3μ, the second filter F2 having a mesh size of 1μ, and the third filter having a mesh size of 0.5μ. By sequentially passing F3, the entire fluorescent paint can be recovered efficiently and efficiently.
[0068] 濯ぎ液剤が、洗浄タンク Α2に供給される際は、濯ぎ液剤貯蔵タンク 9に貯蔵されて V、た濯ぎ液剤力 液剤供給ノズル A3からウェス Xに向カゝつて一定の圧力で噴射され ることで洗浄タンク A2に供給される。 [0068] When the rinsing liquid is supplied to the washing tank Α2, it is stored in the rinsing liquid storage tank 9. V, rinsing liquid power The liquid is supplied to the washing tank A2 by being sprayed from the liquid supply nozzle A3 toward the waste X at a constant pressure.
[0069] 〔排ガス分離部〕 [0069] [Exhaust gas separation unit]
図 3は、排ガス分離部 Dの構成を模式的に示す説明図である。  FIG. 3 is an explanatory diagram schematically showing the configuration of the exhaust gas separation unit D. As shown in FIG.
図 3に示すように、排ガス分離部 Dは、ウェス洗浄機 A内に充満する混合ガスを吸 引し、ウェス洗浄機 A外に排出するための吸引手段 10と、混合ガス中に含まれる気 化した洗浄液剤及又は濯ぎ液剤を液ィ匕させるための液ィ匕装置 11とを備える。  As shown in FIG. 3, the exhaust gas separation unit D sucks the mixed gas that fills the waste washer A and discharges it outside the waste washer A, and the gas contained in the mixed gas. And a liquid rinsing device 11 for liquefying the cleaned cleaning liquid and / or rinsing liquid.
なお、吸引手段 10としては例えば真空ポンプが採用される。  For example, a vacuum pump is employed as the suction means 10.
[0070] 液ィ匕装置 11としては、吸引した混合ガスを冷却して、洗浄液剤又は濯ぎ液剤を液 化させる冷却装置や、吸引したガスを圧縮させることで、洗浄液剤又は濯ぎ液剤を液 ィ匕させる圧縮機等が採用可能である。 [0070] As the liquid supply device 11, the suctioned mixed gas is cooled to liquefy the cleaning liquid or the rinsing liquid, or the suctioned gas is compressed to irrigate the cleaning liquid or the rinsing liquid. It is possible to adopt a compressor that causes drowning.
そして、液ィ匕した洗浄液剤又は濯ぎ液剤は、洗浄液剤貯蔵タンク 5に送られ、再利 用される。  Then, the washed cleaning liquid or rinsing liquid is sent to the cleaning liquid storage tank 5 and reused.
[0071] 次に、ウェス洗浄機によってウェスの洗浄を完了させるまでの操作を、順次工程に 従って説明する。  [0071] Next, an operation until the waste cleaning is completed by the waste washer will be described according to the sequential steps.
ここでウェスとして長尺もの、例えば 600m X l. 5mのものが採用される。 図 4は、本実施形態に係るウェス洗浄機内で行なわれる工程を示した工程図である いま、ウェス洗浄機内に洗浄する対象となるウェスが第 1のリールに巻かれることに より投入されたと想定する。  Here, a long one, for example, 600 m × l.5 m is used as the waste. FIG. 4 is a process diagram showing the steps performed in the waste washer according to the present embodiment. It is assumed that the waste to be cleaned in the waste washer is introduced by being wound around the first reel. To do.
[0072] 始めに、ウェス洗浄機内の減圧 S1が行われる(減圧工程)。 [0072] First, pressure reduction S1 in the waste washer is performed (pressure reduction step).
ウェス洗净機内の減圧 S1はウェス洗浄機内の空気を、排ガス分離部 Dに設けられ た吸引手段 10を用いて吸引し、ウェス洗浄機内の気圧をゲージ圧で一定圧 (例えば 90kPa)まで低下させる。  Depressurization in the waste washer S1 sucks the air in the waste washer using the suction means 10 provided in the exhaust gas separation part D, and reduces the atmospheric pressure in the waste washer to a constant pressure (for example, 90 kPa) with a gauge pressure. .
[0073] ウェス洗浄機内の減圧 S1が完了した後には、不燃性ガスの充填 S 2が行われる。 [0073] After the pressure reduction S1 in the waste washer is completed, a non-combustible gas filling S2 is performed.
不燃性ガスは、窒素等の不燃性ガスを、ウェス洗浄機内の圧力がゲージ圧で一定 圧(例えば— 20kPa〜― lOkPa)になるまで、ウェス洗浄機内へ充填される。  The incombustible gas is filled into the waste washer until the pressure in the waste washer reaches a constant pressure (for example, -20 kPa to -lOkPa).
ウェス洗净機内に不燃性ガスを充填することで、後述するように、気化した洗浄液 剤又は気化した濯ぎ液剤が静電気等の発生により突然、発火し爆発するのを防止す ることがでさる。 By filling the waste washer with a non-combustible gas, as described later, the vaporized cleaning liquid It is possible to prevent the agent or vaporized rinsing liquid from suddenly igniting and exploding due to the occurrence of static electricity.
[0074] なお、不燃性ガスの充填が完了した際における、ウェス洗浄機内の酸素濃度を 6% 以下にすることが好ましい。  [0074] It is preferable that the oxygen concentration in the waste washer is 6% or less when the filling of the nonflammable gas is completed.
すなわち、洗浄液剤または濯ぎ液剤として主に用いられるメタノールは、気化状態 では周囲の酸素濃度が 6%以下であるときには燃焼しな 、と 、う性質を有して 、るた め、不燃性ガスの充填 S2が完了した際のウェス洗浄機内の酸素濃度を 6%以下に することで、安全にメタノールを用いることができるようになる。  That is, methanol, which is mainly used as a cleaning liquid or a rinsing liquid, has a property that it does not burn in the vaporized state when the ambient oxygen concentration is 6% or less, and is therefore a nonflammable gas. By reducing the oxygen concentration in the waste washer when filling S2 is completed to 6% or less, methanol can be used safely.
[0075] このような酸素濃度の調整は、後述する洗浄工程,濯ぎ工程、又は乾燥工程にお いて、危険防止の観点力 常時行われる。 [0075] Such adjustment of the oxygen concentration is always performed in terms of risk prevention in a cleaning process, a rinsing process, or a drying process, which will be described later.
[0076] なお、酸素濃度は洗浄機本体内に設けられた図示しない濃度センサによって常時 計測される。 Note that the oxygen concentration is constantly measured by a concentration sensor (not shown) provided in the cleaning machine main body.
不燃性ガスの充填が完了した後、洗浄タンク内に洗浄液剤の供給 S3が行われ、一 定量が貯留される。  After the filling of the non-combustible gas is completed, the cleaning liquid supply S3 is performed in the cleaning tank, and a certain amount is stored.
[0077] 洗浄液剤の供給が完了するまで、第 1のリール及び第 2のリールを交互に駆動して 、順方向及び逆方向のウェスの巻き取りを交互に繰り返し行う。  [0077] Until the supply of the cleaning liquid is completed, the first reel and the second reel are alternately driven, and the waste of the waste in the forward direction and the reverse direction is alternately repeated.
ウェスの卷取りが行われて ヽる最中、洗浄液剤は移動するウェスの幅全体に渡つ て液剤供給用のノズル A3から一定圧力で噴射されて、洗浄タンクに所定の量が貯 留される。  While the waste is being removed, the cleaning liquid is sprayed at a constant pressure from the nozzle A3 for supplying the liquid over the entire width of the moving waste, and a predetermined amount is stored in the cleaning tank. The
このことが、蛍光塗料のウエスカもの分離に役立つことは既に述べた。  It has already been described that this is useful for the separation of fluorescent paints.
[0078] 洗浄液剤の供給 S3が完了した後には、ウェスの洗浄 S4が行われる(洗浄工程)。 [0078] After the supply S3 of the cleaning liquid is completed, the waste cleaning S4 is performed (cleaning step).
ウェスの洗浄工程は、洗浄順工程及び洗浄逆工程の二つの工程力もなる。  The waste washing process also has two process forces, a washing order process and a washing reverse process.
[0079] 図 5は、洗浄順工程及び洗浄逆工程を模式的に示す説明図である。  FIG. 5 is an explanatory view schematically showing a cleaning order process and a cleaning reverse process.
図 5 (a)に示すように、洗浄順工程は、第 2のリール a2が第 1のリール alに巻き取ら れているウェスを、案内ローラー a3を介して洗浄タンク内の洗浄液剤に浸漬させなが ら卷き取る工程である。  As shown in FIG. 5 (a), in the cleaning sequence step, the waste having the second reel a2 wound around the first reel al is immersed in the cleaning liquid in the cleaning tank via the guide roller a3. This is the process of scraping.
また図 5 (b)に示すように、洗浄逆工程は、洗浄順工程とは逆に、第 1のリール alが 第 2のリール a2に巻き取られているウェスを、案内ローラー a3を介して洗浄液剤に浸 漬させながら巻き取る工程である。 In addition, as shown in FIG. 5 (b), in the reverse cleaning step, the first reel al is wound around the second reel a2 via the guide roller a3. Immerse in cleaning solution It is a process of winding while soaking.
このような巻き取りは、例えば 50mZ分の巻き取り速度で行われ、 5往復される。  Such winding is performed, for example, at a winding speed of 50 mZ and is reciprocated five times.
[0080] 上記洗浄順工程と洗浄逆工程とでは、移動するウェスの方向が逆となり、ウェスの 表面に沿った洗浄液剤の相対的な流れる方向が逆になる。 [0080] In the cleaning order process and the cleaning reverse process, the direction of the moving waste is reversed, and the relative flow direction of the cleaning liquid along the surface of the waste is reversed.
そのため、洗浄順工程と洗浄逆工程を繰り返し行なうと、洗浄液剤がウェス表面に 付着する蛍光塗料に対して二方向から力を加えることになり、一方向からのみ力をカロ えた場合よりも、ウエスカも蛍光塗料が効率的に除去されやすい。  For this reason, if the washing sequence process and the washing reverse process are repeated, the cleaning liquid will apply a force from two directions to the fluorescent paint adhering to the surface of the waste cloth. In addition, the fluorescent paint is easily removed efficiently.
また、ウェスの材質が特に繊維布材である場合には、該繊維布材の繊維の隙間に 洗浄液剤がムラなく浸透し、ウェスを一方向に移動させながら洗浄液剤に浸漬させた 場合よりも、洗浄効果が高まる。  In addition, when the cloth material is a fiber cloth material, the cleaning liquid penetrates the gaps between the fibers of the fiber cloth material evenly, and the cloth is moved in one direction while being immersed in the cleaning liquid. The cleaning effect is enhanced.
[0081] ところで、洗浄液剤としては、蛍光塗料を含む榭脂を効率よく溶かすと ヽぅ観点から 、洗浄液剤にはメタノールを用いることが好まし 、。 [0081] By the way, as the cleaning liquid, it is preferable to use methanol as the cleaning liquid from the viewpoint of efficiently dissolving the resin containing the fluorescent paint.
また、洗浄液剤として、メタノール及び酢酸の混合物を用いることがより好ましい。 洗浄液剤における酢酸の含有率が 8〜24体積%であると、繊維質の破損等に伴う ウェスの耐久性低下を抑制することができる。  Moreover, it is more preferable to use a mixture of methanol and acetic acid as the cleaning liquid. When the content of acetic acid in the cleaning liquid is 8 to 24% by volume, it is possible to suppress a decrease in the durability of the cloth due to fiber breakage or the like.
[0082] また、洗浄液剤として、メタノール及び酢酸の混合物に、更にリモネンが添加された ものを用いることがさらに好ま 、。  [0082] Further, it is more preferable to use a cleaning liquid obtained by adding limonene to a mixture of methanol and acetic acid.
洗浄液剤中でリモネンは、いわゆる相間移動触媒として機能するため、繊維布材か ら付着物がより一層効率よく除去される。  In the cleaning liquid, limonene functions as a so-called phase transfer catalyst, so that deposits are more efficiently removed from the fiber cloth material.
このとき、洗浄液剤中のリモネンの含有率は 0. 01-1. OmlZlであることが好まし い。  At this time, the limonene content in the cleaning solution is preferably 0.01-1.OmlZl.
[0083] ウェスの洗浄 S4が完了した後には、洗浄液剤の排出 S5が行われる。  [0083] After the waste cleaning S4 is completed, the cleaning liquid is discharged S5.
すなわち洗浄タンク A2から洗浄液剤を排出させ、洗浄液剤供給回収部 Bへ送る。 洗浄液剤供給回収部 Bに洗浄液剤が送られると、洗浄液剤供給回収部 Bでは、洗 浄液剤から蛍光塗料を除去し (第一蛍光塗料回収工程)、蛍光塗料が除去された洗 浄液剤を、次のバッチ処理における洗浄液剤の供給が再び開始されるまで貯蔵する なお、洗浄液剤供給回収部 Bが、目の粗さを異にする複数のろ過用のフィルターを 備えている場合、第一蛍光塗料回収工程において、より効率の良い蛍光塗料の除去 が可能となる。 That is, the cleaning liquid is discharged from the cleaning tank A2 and sent to the cleaning liquid supply and recovery unit B. When the cleaning liquid is sent to the cleaning liquid supply / recovery section B, the cleaning liquid supply / recovery section B removes the fluorescent paint from the cleaning liquid (first fluorescent paint recovery process) and supplies the cleaning liquid from which the fluorescent paint has been removed. The cleaning liquid supply in the next batch process is stored until it is restarted.The cleaning liquid supply and recovery section B has a plurality of filtration filters with different eye roughnesses. If so, the fluorescent paint can be removed more efficiently in the first fluorescent paint recovery process.
[0084] 洗浄液剤の排出 S5が行われ、全ての洗浄液剤が洗浄タンクカゝら排出されると、今 度は濯ぎ液剤の供給 S6が開始され洗浄タンク内に一定量が貯留される。  [0084] When the cleaning liquid discharge S5 is performed and all the cleaning liquid is discharged from the cleaning tank cover, the rinsing liquid supply S6 is started and a fixed amount is stored in the cleaning tank.
濯ぎ液剤の供給が完了するまで、第 1のリール al及び第 2のリール a2を交互に駆 動して、順方向及び逆方向のウェスの巻き取りを交互に繰り返し行う。  Until the supply of the rinsing liquid is completed, the first reel al and the second reel a2 are alternately driven, and the winding of the waste in the forward direction and the reverse direction is alternately repeated.
ウェスの卷取りが行われている最中、濯ぎ液剤は、移動するウェスの幅全体に渡つ て液剤供給用のノズル A3から一定圧力で噴射されて、洗浄タンク A2に所定の量が 貯留される。  During waste cutting, the rinsing liquid is sprayed at a constant pressure from the liquid supply nozzle A3 over the entire width of the moving waste, and a predetermined amount is stored in the cleaning tank A2. The
このことが、蛍光塗料のウエスカ の分離に役立つ。  This is useful for separating Huescas of fluorescent paint.
[0085] 洗浄タンク内に所定の量の濯ぎ液剤が貯留されると、ウェスの濯ぎ S7が行われる( 濯ぎ工程)。 [0085] When a predetermined amount of the rinsing liquid is stored in the washing tank, the rinsing S7 of the waste is performed (rinsing step).
このウェスの濯ぎ S7における濯ぎ方法は、先述したウェスの洗浄 S4における洗浄 方法と同じ方法で行われる。  The rinsing method in the waste rinsing S7 is performed in the same manner as the cleaning method in the above-described waste washing S4.
すなわち、濯ぎ工程は、第 1のリール alに巻かれたウェスを、第 2のリール a2が案 内ローラーを介して、濯ぎ液剤に浸漬させながら巻き取る濯ぎ順工程と、第 2のリー ルに卷かれたウェスを、第 1のリールが案内ローラーを介して、濯ぎ液剤に浸漬させ ながら巻き取る濯ぎ逆工程とよりなり、それらが相互に繰り返し行われウェスの濯ぎ作 用が効率よく遂行される。  That is, the rinsing process includes a rinsing sequence process in which the waste wound on the first reel al is wound up while the second reel a2 is immersed in the rinsing liquid via the inner roller, and the second reel. It consists of a reverse rinsing process in which the first reel is wound up while the first reel is immersed in the rinsing liquid via the guide roller, and these are repeatedly performed to efficiently perform the rinsing operation of the waste. .
このような巻き取りは、例えば 50mZ分の巻き取り速度で行われ、 3往復される。  Such winding is performed, for example, at a winding speed of 50 mZ and is reciprocated three times.
[0086] またここでも、蛍光塗料を含む榭脂を効率よく溶かすことができるという観点から、洗 浄液剤と同様に濯ぎ液剤としてメタノール、又は酢酸を含有させたメタノール、を用い ることが好ましい。 [0086] Here, too, it is preferable to use methanol or methanol containing acetic acid as a rinsing liquid as in the case of the cleaning liquid, from the viewpoint that the resin containing the fluorescent paint can be dissolved efficiently.
酢酸の含有率を 8〜24体積%とすることや、また、濯ぎ液剤に更にリモネンを含有 させ、濯ぎ液剤中のリモネンの含有率を 0. 01〜: L OmlZlとする点についても同様 なことがいえる。  The same applies to the content of acetic acid being 8 to 24% by volume, and further including limonene in the rinsing solution, and the content of limonene in the rinsing solution being 0.01 to: L OmlZl. I can say.
なお、先述した洗浄液剤とは最初の洗浄におけるバッジ処理で使用する液剤を ヽ い、濯ぎ液剤とは、その後の濯ぎにおけるバッジ処理で使用する液剤をいう。 [0087] ウェスの濯ぎ S7が完了した後には、濯ぎ液剤の排出 S8が行われる。 すなわち洗浄タンク力も濯ぎ液剤を排出させ、濯ぎ液剤供給回収部 Cへ送る。 濯ぎ液剤供給回収部 Cに濯ぎ液剤が送られると、濯ぎ液剤供給回収部 Cでは、濯 ぎ液剤から蛍光塗料を除去し (第二蛍光塗料回収工程)、蛍光塗料が除去された濯 ぎ液剤を濯ぎ液材の供給が再び開始されるまで貯蔵する。 The above-mentioned cleaning liquid refers to the liquid used in the badge process in the first cleaning, and the rinsing liquid refers to the liquid used in the badge process in the subsequent rinsing. [0087] After the waste rinsing S7 is completed, the rinsing liquid is discharged S8. That is, the washing tank power is also discharged to the rinsing liquid supply and recovery unit C. When the rinsing liquid is sent to the rinsing liquid supply / recovery section C, the rinsing liquid supply / recovery section C removes the fluorescent paint from the rinsing liquid (second fluorescent paint recovery process), and then removes the rinsing liquid from which the fluorescent paint has been removed. Store until rinsing fluid supply is started again.
なお、濯ぎ液剤供給回収部が目の粗さを異にする複数のろ過用のフィルターを備 えている場合、第二蛍光塗料回収工程において、より効率の良い蛍光塗料の除去が 可能となる。  If the rinsing liquid supply / recovery unit is equipped with a plurality of filtration filters having different eye roughnesses, the fluorescent paint can be more efficiently removed in the second fluorescent paint recovery process.
[0088] 濯ぎ液剤の排出 S8が行われ、全ての濯ぎ液剤が洗浄タンクから排出されると、今 度はウェスの乾燥 S9が行われる(乾燥工程)。  [0088] When the rinsing liquid is discharged S8 and all the rinsing liquid is discharged from the washing tank, the waste is dried S9 (drying step).
ウェスの乾燥 S9は、効率ィ匕の観点から、ウェス洗浄機内の温度を上昇させて行う。 ウェスに染み込んでいた濯ぎ液剤が気化されてウェスが乾燥する。  Drying the waste S9 is performed by increasing the temperature in the waste washer from the viewpoint of efficiency. The rinsing liquid soaked in the waste is vaporized and the waste is dried.
ここでウェス洗浄機内の温度に関しては、洗浄液剤がメタノールである場合、ウェス 洗浄機内で制御される圧力、すなわちゲージ圧で— 20kPa〜― lOkPaの状態にお ける沸点以上にされる。  Here, when the cleaning liquid is methanol, the temperature in the waste washer is set to a pressure controlled in the waste washer, that is, a gauge pressure equal to or higher than the boiling point in a state of −20 kPa to −10 kPa.
このように使用する洗浄液剤の沸点以上に加熱することは気化を促すことから重要 である。  Heating above the boiling point of the cleaning liquid used in this way is important because it promotes vaporization.
このようなことから、熱効率を考慮して例えば 55°C程度に制御される。  For this reason, the temperature is controlled to about 55 ° C. in consideration of thermal efficiency.
ウェスの乾燥は、第 1のリールに巻かれたウェスを第 2のリールが巻き取る乾燥順ェ 程と、第 2のリールに巻かれたウェスを第 1のリールが巻き取る乾燥逆工程と、が交互 に繰り返し行われる。  The drying of the waste includes a drying process in which the second reel winds the waste wound on the first reel, and a reverse drying process in which the first reel winds the waste wound on the second reel. Are repeated alternately.
なお、ウェスの乾燥 S9は、ウェスの長さが例えば 600mであれば 4時間程度行われ る。  The waste drying S9 is performed for about 4 hours if the waste length is 600 m, for example.
この際、第 1のリールと第 2のリールとにより交互に巻き取りが行われ乾燥順工程、 乾燥逆工程が遂行される。  At this time, winding is alternately performed by the first reel and the second reel, and the drying order process and the drying reverse process are performed.
なお、ウェスの巻き取られる速さは、好ましくは 6mZ分程度である。  The speed at which the waste is wound is preferably about 6 mZ.
[0089] ここで、ウェスの乾燥中に気化した濯ぎ液剤によって、ウェス洗浄機内の気圧が上 昇し、濯ぎ液材の気化速度を減少させる傾向がある。 このことを防止するために、ウェス洗浄機内の気圧が所定の値 (例えば 20kPa〜 - lOkPa)を上回った際にはウェス洗浄機内の混合ガスの排気 S10がその都度行わ れる。 Here, the rinsing liquid evaporated during the drying of the waste tends to increase the atmospheric pressure in the waste washer and reduce the vaporization rate of the rinsing liquid. In order to prevent this, when the atmospheric pressure in the waste washer exceeds a predetermined value (for example, 20 kPa to -lOkPa), the mixed gas in the waste washer is exhausted S10 each time.
混合ガスは、排ガス分離部 Dが備える吸引手段 10により、ウェス洗浄機外へ排出さ れる。  The mixed gas is discharged out of the waste washer by the suction means 10 provided in the exhaust gas separation part D.
[0090] 混合ガスは、ウェス洗浄機に設けられたガス排出口 A5からウェス洗浄機外に排出 され、排ガス分離部 Dが備える液ィ匕装置 11へと送られる。  [0090] The mixed gas is discharged out of the waste washer from a gas discharge port A5 provided in the waste washer, and is sent to the liquid tank device 11 provided in the exhaust gas separator D.
混合ガスが液化装置 11へ送られると、気化して ヽる洗浄液剤又は濯ぎ液剤は液ィ匕 して、混合ガスから分離される。  When the mixed gas is sent to the liquefying device 11, the cleaning liquid or the rinsing liquid that is vaporized is liquidized and separated from the mixed gas.
そして、液ィ匕した洗浄液剤又は濯ぎ液剤は洗浄液剤貯蔵タンク 5に送られ、再利用 される。  The washed cleaning liquid or rinsing liquid is sent to the cleaning liquid storage tank 5 and reused.
洗浄液剤又は濯ぎ液剤が分離されて回収された後の混合ガスは、適時、吸引手段 10から大気中へと放出される。  The mixed gas after the cleaning liquid or the rinsing liquid is separated and collected is discharged from the suction means 10 into the atmosphere at an appropriate time.
[0091] ウェスの乾燥 S9が完了した後は、混合ガスの排出 S10が行われ、その排出の後、 不燃性ガスの充填 S 11が行われる。 [0091] After drying S9, the mixed gas discharge S10 is performed, and after the discharge, nonflammable gas filling S11 is performed.
ウェス洗净機内の気圧を大気圧と同じ大きさにするために、ウェス洗浄機内に窒素 等の不燃性ガスが充填される。  In order to make the pressure inside the waste washer as large as the atmospheric pressure, the waste washer is filled with non-combustible gas such as nitrogen.
不燃性ガスの充填 S11を行うことにより、爆発等の危険性を回避しながらウェス洗 浄機を容易に開放することができるようになる。そして、ウェス洗浄機カゝらウェスを取り 出すことで、ウェスの洗浄の全工程が完了する。  Filling with non-flammable gas S11 makes it possible to easily open the waste washer while avoiding the danger of explosion. Then, by removing the waste cloth from the waste washer, the entire waste washing process is completed.
[0092] 以上本発明を述べてきた力 本発明はその目的に沿う限り、種々の変更が可能で ある。 [0092] Powers that have described the present invention As described above, various modifications can be made to the present invention as long as the object is met.
例えば洗浄機本体内の空間は、少なくとも、洗浄タンク及びウェスを巻き取るため の一対のリールを備えるだけの容積があれば種々の設計変更可能である。  For example, the design of the space in the main body of the cleaning machine can be changed in various ways as long as it has at least a capacity for providing a cleaning tank and a pair of reels for winding the waste cloth.
また、図 1におけるポンプやバルブの位置は、洗浄液剤供給回収部、濯ぎ液剤供 給回収部、排ガス分離部等の機能が達成できる限り、その位置や数は問わない。 また、洗浄工程や濯ぎ工程において、第 1及び第 2のリールを使って巻き取る際、ど ちらのリールを最初の巻き取り状態にするかは自由である。 産業上の利用可能性 In addition, the positions of the pumps and valves in FIG. 1 are not limited as long as the functions such as the cleaning liquid supply / recovery unit, the rinsing liquid supply / recovery unit, and the exhaust gas separation unit can be achieved. In the cleaning process and the rinsing process, when winding with the first and second reels, it is free to decide which reel is in the initial winding state. Industrial applicability
[0093] 本発明は、蛍光塗料が付着したウェスを洗浄することで該ウェスを再利用可能にし 、且つ、蛍光塗料に含まれる金属蛍光体を回収することが可能なウェス洗浄装置及 び洗浄方法に関するものであるが、その原理を用いる限り、他のウェス洗浄分野にお ける装置に十分適用可能であり、その応用分野は広い。  [0093] The present invention provides a waste cleaning apparatus and a cleaning method capable of reusing a waste cloth by washing the waste cloth to which the fluorescent paint is adhered, and collecting a metal phosphor contained in the fluorescent paint. However, as long as the principle is used, it is sufficiently applicable to apparatuses in other waste cleaning fields, and its application fields are wide.
