食生成物を捕獲する高温吸着処理方法に関する。[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is directed to the treatment of copper, iron, etc. eluted from piping systems, heat exchangers, etc. contained in high-temperature cooling water of fuel cells. This invention relates to a high temperature adsorption treatment method for capturing heavy metal corrosion products.

、燃料となる水素と酸素の化学エネルギが直接電気エネ

。(Prior art) A fuel cell generates electricity by causing hydrogen and oxygen to slowly react in a reactor using a catalyst, and the chemical energy of the hydrogen and oxygen used as fuel is directly converted into electrical energy. It is more efficient than other power generation methods.

低いものを使用する。In this case, electricity is generated while producing water through the reaction between hydrogen and oxygen, but at the same time heat is also generated, so in order to maintain high power generation efficiency, the temperature inside the reaction vessel must be kept at 160-160℃.
It is necessary to maintain the temperature at 230°C, and cooling water is constantly flowing into the reactor. This cooling water is 5 to 10 degrees Celsius higher than the temperature inside the reactor.
Use a low one.

造上、電位が加わっており。That is, it is a high temperature of 150 to 225°C. Corrosion products of heavy metals such as copper or iron are leached into the cooling water from the inner walls of cooling pipes and other piping, joints, tanks, heat exchangers, etc. Furthermore, due to the structure of the fuel cell, an electric potential is applied to the cooling pipes and their joints.

くする。In addition to accelerating corrosion, it also tends to attract or deposit heavy metal corrosion products. This cooling water flows through a circulation channel,
If the treatment continues for a long time, the above-mentioned adhesion and deposition will progress and some of the cooling pipes and their joints will become clogged, resulting in uneven temperature distribution within the reactor, reducing power generation efficiency and shortening battery life. do.

ン交換樹脂で低温浄化していた。In order to suppress the adhesion and accumulation of heavy metal corrosion products to the cooling pipes and joints, it is necessary to maintain the quality of the cooling water at a high purity. Conventionally, some of this cooling water was taken out of the circulation system,
After the temperature was lowered to 40 to 60°C using a heat exchanger (cooler), low-temperature purification was performed using an ion exchange resin.

かった。従って、高温状態の冷却水中かＪう重金属腐食
生成物を除去できることが要望されている。However, low-temperature purification using ion exchange resin has a large energy loss, so this amount is reduced to 10% of the amount of circulating cooling water.
It was not practical to set the concentration to 10% or more, and sufficient purification could not be achieved. Therefore, it is desired to be able to remove heavy metal corrosion products from cooling water at high temperatures.

した。The present inventors have confirmed through experiments that manganese dioxide is optimal as a high-temperature adsorption filter material that can be applied to this treatment. It was also confirmed that electrolytic manganese dioxide produced by electrolysis is suitable as this manganese dioxide adsorption filter material.

よる腐食を防止する必要がある。The sulfate in this electrolytic manganese dioxide dissolves into sulfuric acid H2SO4 in high temperature water (150 to 225°C) such as cooling water of a fuel cell. When sulfuric acid is eluted into cooling water, it corrodes cooling pipes, piping, joints, tanks, etc., and significantly accelerates clogging of cooling pipes and piping. Therefore, it is necessary to prevent corrosion caused by this sulfuric acid.

本発明者らは電解二酸化マンガンから溶出した硫酸によ

酸は冷却管。The amount of sulfate eluted from electrolytic manganese dioxide is extremely high immediately after the start of water flow treatment, decreases over time, and finally stops eluting. The sulfuric acid eluted into this cooling water is in the cooling pipe.

処理塔７の出口配管８に接続する。This high-temperature adsorption treatment tower 7 accommodates electrolytic manganese dioxide as a high-temperature adsorption filter material. The outlet pipe 8 of the high-temperature adsorption treatment tower 7 is connected to the inlet of the cooling pipe 2 via an on-off valve 9, thereby forming a cooling water circulation system. Further, the cooling water outlet pipe 4 is branched, and the branch side has an on-off valve 10.
After connecting to a cooler 11 via a cooler 11, it is connected to a low temperature purifier 12 made of ion exchange resin or the like. An outlet pipe 13 of the low temperature purifier 12 is connected to the gas-liquid separator 3 via a pump 14 and a heater 15. On the other hand, an alkali tank 16 containing alkali such as sodium hydroxide and potassium hydroxide is connected to a pressure pump 17. The outlet pipe 18 of this pressurizing pump 17 is connected to the outlet pipe 8 of the high temperature adsorption treatment tower 7 via a heater 19 and an on-off valve 20.

示す低温浄化が必要となる。First, the on-off valves 6 and 9 are opened, and the on-off valves 1.0.20 are closed. Cooling water is in the cooling pipe 2. It passes through the gas-liquid separator 3 and various piping, and contains heavy metal corrosion products generated therefrom. This cooling water is sent to the high temperature adsorption treatment tower 7 by the circulation pump 5. The high temperature adsorption treatment tower 7 contains electrolytic manganese dioxide for adsorption treatment of these heavy metal corrosion products. This electrolytic manganese dioxide efficiently adsorbs heavy metals in high-temperature hot water such as cooling water for fuel cells. This main festival'manganese dioxide is a substance other than heavy metals, such as carbon dioxide.
Since anions such as Q- and 5oH- cannot be adsorbed, the following low-temperature purification is required.

Processing is performed using a low temperature purifier 12 such as ion exchange resin.

め、上記のアルカリ溶液の供給はその期間だけでよい。This will corrode tanks, etc., so take the following steps to prevent corrosion. Open the on-off valve 20, pressurize the alkali solution in the alkali tank 16 with the pump 17, raise the temperature to the same level as the cooling water with the heater 9, pass it through the on-off valve 20, and enter the outlet pipe 8 of the high-temperature adsorption treatment tower 7. supply The alkaline solution supplied to the outlet pipe 8 neutralizes the sulfuric acid eluted into the cooling water in the high temperature adsorption treatment tower 7. Since cooling pipes and the like are less corroded in alkaline conditions than in acidic conditions, neutralization is performed to make them neutral or slightly alkaline. Although corrosion caused by sulfuric acid can be prevented by neutralizing in this way, since the salt concentration (for example, sodium sulfate when neutralized with sodium hydroxide) is high, it is necessary to remove these salts with the low temperature purifier 12. . However, the sulfate content of this electrolytic manganese dioxide is approximately 1%.
Since the elution ends within a period of time after the start of the treatment, the above-mentioned alkaline solution needs to be supplied only during that period.

また、低温浄化器１２として、イオン交換樹脂を使用し

必要な樹脂量は５００〜６００ｋｇと推定される。Further, when an ion exchange resin is used as the low temperature purifier 12, the amount of resin required for removing sulfates is estimated to be 500 to 600 kg for 1 liter of electrolytic manganese dioxide.

Furthermore, the accuracy of neutralization may be improved by measuring the pH or acidity of the cooling water discharged from the high-temperature adsorption treatment tower 7 and supplying an amount of alkaline solution corresponding to the pH or acidity.

不必要となる。In the above example, the sulfuric acid eluted after filling electrolytic manganese dioxide containing sulfate into the high-temperature adsorption treatment tower 7 was neutralized with an alkali. By using electrolytic manganese dioxide impregnated with manganese dioxide, it is possible to neutralize it with the eluted sulfuric acid and alkali. In this case, an alkaline solution supply device becomes unnecessary.
