に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a high-temperature adsorption treatment device that directly adsorbs and removes heavy metal corrosion products dissolved in fuel cell cooling water or the like under high-temperature hydrothermal conditions.

防止するため、循環冷却水の一部を分岐して温度を約６
０℃以下に下げた後、イオン交換樹脂を用いた低温浄化
装置により浄化している。For this reason, the heat of reaction during power generation is controlled by passing cooling water through a cooling pipe inside the cell. Steel pipes are used for cooling pipes due to their thermal conductivity and workability, but trace amounts of corrosion products of heavy metals such as copper and iron are eluted from the cooling pipes and other piping during operation. The eluted heavy metal corrosion products pass through the circulating cooling water and adhere to the inlet of the cooling pipe on the electrode side as oxide scale (cuprous oxide in the case of eluted steel), clogging the cooling pipe. Therefore, in order to prevent such blockage accidents, in conventional actual plants, part of the circulating cooling water is branched off to reduce the temperature to about 6.
After lowering the temperature to below 0°C, it is purified using a low-temperature purification device using ion exchange resin.

離器２から直接流れてくる液と再び合流する。A conventional fuel cell cooling water plant will be explained with reference to FIG. Cooling water discharged from a cooling pipe built into the battery body 1 is separated into gas and liquid by a gas-liquid separator 2. The separated cooling water becomes a liquid, passes through a valve 3, is pressurized by a pump 4, and is again supplied to the battery body 1 through a valve 5. A part of this circulating cooling water (150 to 190°C) is branched, passes through a valve 6, is pressurized by a pump 7, is lowered in temperature to about 60°C or less in a heat exchanger 8, and is then sent to an ion exchange resin column. 9
Heavy metal corrosion products are removed. This treated liquid rejoins the liquid flowing directly from the gas-liquid separator 2.

中で重金属腐食生成物を吸着除去できる高温吸着処理装
置が要望されてきている。(Problem to be Solved by the Invention) However, in the fuel cell cooling water plans 1 to 1 described above, the cooling water is cooled to below the heat-resistant temperature of the ion exchange resin (approximately 60°C) before being processed, resulting in a large heat loss. This results in lower power generation efficiency of the fuel cell. In other words, heat loss increases in proportion to the processing flow rate, and power generation efficiency also decreases. Therefore, there is a limit to the processing flow rate, and it is difficult to prevent the cooling pipes from clogging with the current methods. For these reasons, there is a need for a high-temperature adsorption treatment device that can adsorb and remove heavy metal corrosion products in high-temperature hot water.

発表されている。In order to achieve the above requirements, the inventors began investigating high-temperature adsorbents. As a result, we confirmed that inorganic adsorbents are effective in adsorbing heavy metal ions under high-temperature hydrothermal conditions. Inorganic adsorbents have better heat resistance than ion exchange resins, and have already been used in Amphlett's "I Norga".

を長時間安定に動作させる対策が必要となる。The present inventor has confirmed through experiments that manganese dioxide has excellent properties as a high-temperature adsorption filter material that can be applied to the high-temperature purification system of the fuel cell. This manganese dioxide can adsorb and remove not only ions but also insoluble colloids and crud. However, if the treatment is carried out for a long time, the pressure loss will increase due to the adhesion of colloids and crud. Therefore, measures are required to ensure stable operation of the device for a long period of time.

The purpose of this invention is to provide a processing device.
