Description

本発明は、アルカリ蓄電池の製造工程で排出される廃液を処理する廃液処理装置に関する。   The present invention relates to a waste liquid treatment apparatus for treating waste liquid discharged in a manufacturing process of an alkaline storage battery.

アルカリ蓄電池の製造の際には、電解液の注液工程において電解液成分の水酸化カリウム等を含むアルカリ水溶液が廃液として大量に排出される。そこで、前記廃液からアルカリ水溶液を回収する技術が検討されている。   When manufacturing an alkaline storage battery, a large amount of an alkaline aqueous solution containing potassium hydroxide or the like as an electrolytic solution component is discharged as a waste solution in the electrolytic solution pouring step. Thus, a technique for recovering an alkaline aqueous solution from the waste liquid has been studied.

前記廃液からアルカリ水溶液を回収する装置として、従来、陽極と陰極との間に、陽極室と、陰極室とを形成した電気透析装置が知られている（例えば特許文献１参照）。   As an apparatus for recovering an alkaline aqueous solution from the waste liquid, an electrodialysis apparatus in which an anode chamber and a cathode chamber are formed between an anode and a cathode has been conventionally known (see, for example, Patent Document 1).

前記電気透析装置において、前記陽極室は、陽極側がバイポーラ膜、陰極側が陽イオン交換膜で仕切られている。また、前記陰極室は、陽極側が陽イオン交換膜、陰極側がバイポーラ膜で仕切られている。   In the electrodialysis apparatus, the anode chamber is partitioned by a bipolar membrane on the anode side and a cation exchange membrane on the cathode side. The cathode chamber is partitioned by a cation exchange membrane on the anode side and a bipolar membrane on the cathode side.

前記装置では、前記陽極室に前記アルカリ水溶液として水酸化カリウムを含む廃液を供給し、前記陰極室に回収媒体液を供給して電気透析を行う。この結果、前記陰極側室から該廃液より高濃度の水酸化カリウムを含むアルカリ水溶液を回収することができるとされている。   In the apparatus, waste liquid containing potassium hydroxide as the alkaline aqueous solution is supplied to the anode chamber, and a recovery medium solution is supplied to the cathode chamber to perform electrodialysis. As a result, an alkaline aqueous solution containing potassium hydroxide having a higher concentration than the waste liquid can be recovered from the cathode side chamber.

特開２００９−２１３２３８号公報（段落〔０００６〕）JP 2009-213238 A (paragraph [0006])

しかしながら、前記従来の装置は、バイポーラ膜及び陽イオン交換膜等の高価な膜材料を用いるので、コストの増大が避けられないという不都合がある。   However, since the conventional apparatus uses expensive membrane materials such as a bipolar membrane and a cation exchange membrane, there is a disadvantage that an increase in cost is inevitable.

本発明は、かかる不都合を解消して、アルカリ蓄電池の製造の際に排出される廃液を処理することができる安価な廃液処理装置を提供することを目的とする。   An object of the present invention is to provide an inexpensive waste liquid treatment apparatus capable of solving such inconvenience and treating waste liquid discharged during the production of an alkaline storage battery.

かかる目的を達成するために、本発明は、アルカリ蓄電池の製造の際に排出される廃液を処理する廃液処理装置であって、電解槽と、該電解槽内に配設された素焼部材に仕切られた陽極室及び陰極室と、該陽極室内に設けられた陽極と、該陰極室内に設けられた陰極と、該陽極及び該陰極に電解電圧を印加する電圧印加手段とを備え、該陽極室に該廃液を供給すると共に、前記陰極室に回収媒体液を供給し、該電圧印加手段により該陽極及び該陰極に電解電圧を印加して電解を行うことにより、該廃液中の金属イオンの一部を該陰極室に移動させ、該陰極室に該金属イオンを含む水溶液を得ることを特徴とする。   In order to achieve such an object, the present invention provides a waste liquid treatment apparatus for treating a waste liquid discharged during the production of an alkaline storage battery, and is divided into an electrolytic cell and an unglazed member disposed in the electrolytic cell. An anode chamber and a cathode chamber provided; an anode provided in the anode chamber; a cathode provided in the cathode chamber; and a voltage applying means for applying an electrolytic voltage to the anode and the cathode. The waste liquid is supplied to the cathode chamber, the recovery medium liquid is supplied to the cathode chamber, and electrolysis is performed by applying an electrolysis voltage to the anode and the cathode by the voltage applying means. A part is moved to the cathode chamber, and an aqueous solution containing the metal ions in the cathode chamber is obtained.

本発明の廃液処理装置は、電解槽内に素焼部材を配設することにより、該電解槽を陽極室と陰極室とに仕切り、該陽極室内に陽極を設けると共に、該陰極室内に陰極を設け、該陽極及び該陰極は電圧印加手段に接続されている。   The waste liquid treatment apparatus of the present invention has an unglazed member disposed in an electrolytic cell, thereby partitioning the electrolytic cell into an anode chamber and a cathode chamber, providing an anode in the anode chamber, and providing a cathode in the cathode chamber. The anode and the cathode are connected to voltage application means.

本発明の廃液処理装置では、前記陽極室に、アルカリ蓄電池の製造の際に排出される廃液を供給すると共に、前記陰極室に回収媒体液を供給し、前記電圧印加手段により前記陽極及び前記陰極に電解電圧を印加して電解を行う。このようにして電解を行うと、前記素焼部材が陽イオン透過膜として作用し、前記廃液中の金属イオンの一部が該素焼部材を透過して、前記陰極室に移動する。この結果、前記陰極室に前記金属イオンを含む水溶液を得ることができる。   In the waste liquid treatment apparatus according to the present invention, the anode chamber is supplied with the waste liquid discharged during the production of the alkaline storage battery, and is also supplied with the recovery medium liquid to the cathode chamber, and the anode and the cathode are supplied by the voltage application means. Electrolysis is performed by applying an electrolysis voltage to. When electrolysis is performed in this manner, the unglazed member acts as a cation permeable membrane, and a part of the metal ions in the waste liquid permeates the unglazed member and moves to the cathode chamber. As a result, an aqueous solution containing the metal ions in the cathode chamber can be obtained.

本発明の廃液処理装置では、バイポーラ膜及び陽イオン交換膜等の高価な膜材料に代えて前記素焼部材を用いるので、装置を安価に構成することができ、かかる安価な装置によってアルカリ蓄電池の製造の際に排出される前記廃液の処理を行うことができる。   In the waste liquid treatment apparatus of the present invention, since the unglazed member is used in place of expensive membrane materials such as bipolar membranes and cation exchange membranes, the apparatus can be configured at low cost, and the alkaline storage battery can be manufactured by such inexpensive apparatus. The waste liquid discharged during the process can be treated.

本発明の廃液処理装置では、前記電解槽を前記素焼部材により２分して、一方を前記陽極室とし、他方を陰極室としてもよいが、該電解槽の一部の領域を該素焼部材により画成し、その内部を該陽極室とし、外部を該陰極室としてもよい。この場合、前記素焼部材は、板状の部材であってもよいが、該素焼部材として、素焼壺を用いることにより、該素焼部材により画成された領域を容易に形成することができる。即ち、前記素焼壺を用いる場合には、該素焼壺の内部が前記陽極室となり、外部が前記陰極室となる。   In the waste liquid treatment apparatus of the present invention, the electrolytic cell may be divided into two parts by the unglazed member, and one of them may be used as the anode chamber and the other as the cathode chamber. The inside may be the anode chamber and the outside may be the cathode chamber. In this case, the unglazed member may be a plate-shaped member, but by using unglazed soot as the unglazed member, a region defined by the unglazed member can be easily formed. That is, when using the union shochu, the inside of the union shochu becomes the anode chamber and the outside becomes the cathode chamber.

アルカリ蓄電池の製造の際に排出される前記廃液は、前記金属イオンとして、ニッケル、カリウム及びカドミウムを含んでいる。そこで、前記素焼部材は、ニッケル及びカリウムを透過させると共に、カドミウムを吸着する機能を備えることが好ましい。   The waste liquid discharged in the production of the alkaline storage battery contains nickel, potassium and cadmium as the metal ions. Therefore, it is preferable that the unglazed member has a function of allowing nickel and potassium to permeate and adsorbing cadmium.

この場合、前記陰極室には、ニッケルを含む水酸化カリウム水溶液を得ることができる。前記ニッケルは前記水酸化カリウム水溶液から分離して、メッキ材料として用いることができる。また、前記水酸化カリウム水溶液は、濃度を調整することにより、アルカリ蓄電池の製造の際の電解液として用いることができ、或いはカリ肥料として用いることができる。前記水酸化カリウム水溶液をカリ肥料として用いる場合、前記廃液に含まれるカドミウムは有害物となるが、該カドミウムは前記素焼部材に吸着されて除去されており、該水酸化カリウム水溶液は該カドミウムを含まないので好都合である。   In this case, an aqueous potassium hydroxide solution containing nickel can be obtained in the cathode chamber. The nickel can be separated from the potassium hydroxide aqueous solution and used as a plating material. Moreover, the said potassium hydroxide aqueous solution can be used as electrolyte solution at the time of manufacture of an alkaline storage battery by adjusting a density | concentration, or can be used as a potassium fertilizer. When the potassium hydroxide aqueous solution is used as a potash fertilizer, cadmium contained in the waste liquid becomes a harmful substance, but the cadmium is adsorbed and removed by the unglazed member, and the potassium hydroxide aqueous solution does not contain the cadmium. So convenient.

本発明の廃液処理装置では、前記回収媒体液は、純水または前記廃液よりもカリウム濃度の低い水酸化カリウム水溶液であることが好ましい。前記回収媒体液が、前記廃液よりもカリウム濃度の低い水酸化カリウム水溶液である場合、該水酸化カリウム水溶液は、別途調製してもよく、前記陰極室に得られた水酸化カリウム水溶液の濃度を調整したものを用いてもよい。   In the waste liquid treatment apparatus of the present invention, the recovery medium liquid is preferably pure water or a potassium hydroxide aqueous solution having a potassium concentration lower than that of the waste liquid. When the recovery medium liquid is a potassium hydroxide aqueous solution having a lower potassium concentration than the waste liquid, the potassium hydroxide aqueous solution may be prepared separately, and the concentration of the potassium hydroxide aqueous solution obtained in the cathode chamber may be adjusted. You may use what was adjusted.

次に、添付の図面を参照しながら本発明の実施の形態についてさらに詳しく説明する。   Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

図１に示すように、本実施形態のカリウム回収装置１は、電解槽２と、電解槽２内に配設された素焼壺３とを備えている。素焼壺３は、粘土を有底筒状に形成し、６００〜９００℃の範囲の温度で焼成したものであり、例えば、直径０．１〜６００μｍの範囲の微細孔が不規則に形成されているものを用いることができる。   As shown in FIG. 1, the potassium recovery apparatus 1 of the present embodiment includes an electrolytic cell 2 and a raw cautery 3 disposed in the electrolytic cell 2. The union shochu 3 is formed by forming clay into a bottomed cylindrical shape and firing at a temperature in the range of 600 to 900 ° C. For example, micropores in the range of 0.1 to 600 μm in diameter are irregularly formed. Can be used.

カリウム回収装置１では、素焼壺３の内部が素焼壺３により画成された陽極室４となり、陽極室４内に例えばステンレス板からなる陽極５が配設されている。また、電解槽２の素焼壺３の外部の領域が陰極室６となり、陰極室６内に例えばステンレス板からなる陰極７が配設されている。そして、陽極５及び陰極７は、電圧印加手段としての直流電源装置８に電気的に接続されている。   In the potassium recovery apparatus 1, the inside of the union shochu 3 becomes an anode chamber 4 defined by the union shochu 3, and an anode 5 made of, for example, a stainless plate is disposed in the anode chamber 4. Further, a region outside the union cautery 3 of the electrolytic cell 2 becomes a cathode chamber 6, and a cathode 7 made of, for example, a stainless plate is disposed in the cathode chamber 6. The anode 5 and the cathode 7 are electrically connected to a DC power supply device 8 as voltage application means.

カリウム回収装置１では、陽極室４に水酸化カリウムを含む廃液９を供給すると共に、陰極室６に回収媒体液１０を供給し、直流電源装置８により陽極５及び陰極７に電解電圧を印加して電解を行う。廃液９は、アルカリ蓄電池の製造の際に排出されるものであり、例えば、５．０〜１０．０重量％の範囲のカリウムと、１．０〜５．０重量％の範囲のニッケルと、０．５〜２．０重量％の範囲のカドミウムとを含んでいる。尚、前記カリウムは水酸化カリウムとして含まれている。   In the potassium recovery device 1, a waste liquid 9 containing potassium hydroxide is supplied to the anode chamber 4, a recovery medium solution 10 is supplied to the cathode chamber 6, and an electrolytic voltage is applied to the anode 5 and the cathode 7 by the DC power supply device 8. Electrolyze. The waste liquid 9 is discharged when the alkaline storage battery is manufactured, for example, potassium in the range of 5.0 to 10.0% by weight, nickel in the range of 1.0 to 5.0% by weight, And cadmium in the range of 0.5 to 2.0% by weight. The potassium is included as potassium hydroxide.

回収媒体液１０は、純水であってもよく、廃液９よりも水酸化カリウム濃度の低い水酸化カリウム水溶液であってもよい。回収媒体液１０として水酸化カリウム水溶液を用いる場合、その濃度は、例えば０．１〜５．０重量％の範囲とする。   The recovery medium liquid 10 may be pure water or a potassium hydroxide aqueous solution having a potassium hydroxide concentration lower than that of the waste liquid 9. In the case where an aqueous potassium hydroxide solution is used as the recovery medium liquid 10, the concentration is, for example, in the range of 0.1 to 5.0% by weight.

直流電源装置８は、例えば、２．０〜５．０Ｖ、５．０〜１５．０Ａの範囲の直流電流を、５．０〜１２．０時間の範囲の時間、陽極５及び陰極７に供給する。   The DC power supply 8 supplies, for example, a DC current in the range of 2.0 to 5.0 V and 5.0 to 15.0 A to the anode 5 and the cathode 7 for a time in the range of 5.0 to 12.0 hours. To do.

このようにして電解を行うと、素焼壺３が陽イオン透過膜として作用し、陽極室４内のカリウムイオン、ニッケルイオン等の陽イオンが素焼壺３を透過して、陰極室６に移動する一方、カドミウムイオンが素焼壺３に吸着される。この結果、陰極室６に、ニッケルを含むと共に、初期状態の回収媒体液１０よりも高濃度の水酸化カリウム水溶液を得ることができる。   When electrolysis is performed in this way, the union shochu 3 acts as a cation permeable membrane, and cations such as potassium ions and nickel ions in the anode chamber 4 pass through the union shochu 3 and move to the cathode chamber 6. On the other hand, cadmium ions are adsorbed on the raw shochu 3. As a result, an aqueous potassium hydroxide solution containing nickel in the cathode chamber 6 and having a higher concentration than the recovery medium liquid 10 in the initial state can be obtained.

尚、本実施形態では、素焼壺３を用いるものとして説明しているが、粘土を６００〜９００℃の範囲の温度で焼成し、直径０．１〜６００μｍの範囲の微細孔が不規則に形成されているものであれば、素焼壺３に代えて、板状の素焼部材（素焼板）を用いてもよい。素焼板を用いる場合、電解槽２を素焼板により２分して、一方を陽極室４とし、他方を陰極室６としてもよいが、電解槽２の一部の領域を該素焼板により画成し、その内部を陽極室４とし、外部を陰極室６としてもよい。   In the present embodiment, the explanation is made assuming that the raw shochu 3 is used. However, clay is fired at a temperature in the range of 600 to 900 ° C., and micropores in the range of 0.1 to 600 μm in diameter are irregularly formed. As long as it has been used, a plate-shaped unglazed member (unglazed plate) may be used instead of the unglazed porcelain 3. In the case of using an unglazed plate, the electrolytic cell 2 may be divided into two by the unglazed plate, and one side may be used as the anode chamber 4 and the other may be used as the cathode chamber 6. The inside may be the anode chamber 4 and the outside may be the cathode chamber 6.

次に、本発明の実施例を示す。   Next, examples of the present invention will be described.

本実施例では、電解槽２に、素焼壺３を配設し、内容積５．０リットルの陽極室４と、内容積２０．０リットルの陰極室６とを備えるカリウム回収装置１を用いた。   In the present embodiment, the potassium recovery apparatus 1 provided with the union shochu 3 in the electrolytic cell 2, the anode chamber 4 having an internal volume of 5.0 liters, and the cathode chamber 6 having an internal volume of 20.0 liters was used. .

次に、陽極室４に水酸化カリウムを含む廃液９を４．０リットル（４４８０ｇ）供給した。廃液９は、アルカリ蓄電池の製造の際に排出されたものであり、全量に対し８．２重量％の水酸化カリウムと、２．１重量％の範囲のニッケルと、１．３重量％の範囲のカドミウムとをを含んでいた。また、陽極室６に回収媒体液１０として、廃液９より低濃度の２．８重量％の水酸化カリウム水溶液１６．０リットル（１６６４０ｇ）を供給した。   Next, 4.0 liters (4480 g) of waste liquid 9 containing potassium hydroxide was supplied to the anode chamber 4. The waste liquid 9 was discharged during the production of the alkaline storage battery, and was 8.2% by weight of potassium hydroxide, 2.1% by weight of nickel, and 1.3% by weight of the total amount. Of cadmium. Further, 16.0 liters (16640 g) of a 2.8 wt% potassium hydroxide aqueous solution having a lower concentration than the waste liquid 9 was supplied to the anode chamber 6 as the recovery medium liquid 10.

次に、直流電源装置８から、４．０Ｖ、１２．０Ａの直流電流を、１０．０時間に亘って陽極５及び陰極７に供給し、電解を行った。前記電解終了後、廃液９及び回収媒体液１０の水酸化カリウム濃度を測定したところ、廃液９は４．６重量％、回収媒体液１０は３．８重量％であった。従って、陽極室４内の廃液９に含まれていたカリウム３６７ｇのうち、１６８ｇが陰極室６に移動し、回収されたことが明らかである（回収率４５．８％）。   Next, a direct current of 4.0 V and 12.0 A was supplied from the direct current power supply device 8 to the anode 5 and the cathode 7 for 10.0 hours to perform electrolysis. After completion of the electrolysis, the potassium hydroxide concentrations of the waste liquid 9 and the recovery medium liquid 10 were measured. As a result, the waste liquid 9 was 4.6% by weight and the recovery medium liquid 10 was 3.8% by weight. Therefore, it is clear that 168 g of potassium 367 g contained in the waste liquid 9 in the anode chamber 4 moved to the cathode chamber 6 and was recovered (recovery rate 45.8%).

また、廃液９及び回収媒体液１０のニッケル濃度を測定したところ、廃液９は１．３重量％、回収媒体液１０は０．２３重量％であった。従って、陽極室４内の廃液９に含まれていたニッケル９４．１ｇのうち、３９．１ｇが陰極室６に移動し、回収されたことが明らかである（回収率４２．０％）。   Further, when the nickel concentrations of the waste liquid 9 and the recovery medium liquid 10 were measured, the waste liquid 9 was 1.3% by weight and the recovery medium liquid 10 was 0.23% by weight. Therefore, it is clear that 39.1 g of 94.1 g of nickel contained in the waste liquid 9 in the anode chamber 4 moved to the cathode chamber 6 and was recovered (recovery rate 42.0%).

さらに、廃液９及び回収媒体液１０のカドミウム濃度を測定したところ、廃液９は０．８重量％、回収媒体液１０は０．０５重量％であった。従って、陽極室４内の廃液９に含まれていたカドミウム５８．２ｇのうち、８．１ｇが素焼壺３に吸着されたものと考えられる。   Further, when the cadmium concentrations of the waste liquid 9 and the recovery medium liquid 10 were measured, the waste liquid 9 was 0.8% by weight, and the recovery medium liquid 10 was 0.05% by weight. Therefore, it is considered that 8.1 g out of 58.2 g of cadmium contained in the waste liquid 9 in the anode chamber 4 was adsorbed by the raw shochu 3.
