Zusammenfassung: | To reduce initial costs and maintenance costs.SOLUTION: A chemical supply device 200 comprises: a measuring pipe 210 provided with a fluorescence sensor 220 and an ORP sensor 222; a chemical supply part 250 for supplying a chemical to the measuring pipe 210; a switching control unit 290 for switching between a first control state for introducing cooling water from a first cooling water circulation device 110A to the measuring pipe 210 and introducing the cooling water discharged from the measuring pipe 210 to the first cooling water circulation device 110A again, and a second control state for introducing cooling water from a second cooling water circulation device 110B to the measuring pipe 210 and introducing the cooling water discharged from the measuring pipe 210 to the second cooling water circulation device 110B again; and a supply control unit 292 for controlling an amount of the chemical to be supplied by the chemical supply part 250 on the basis of a measurement result of one or both of the fluorescence sensor 220 and the ORP sensor 222.SELECTED DRAWING: Figure 1
【課題】初期コストおよびメンテナンスコストを低減する。【解決手段】薬剤供給装置200は、蛍光センサ220およびORPセンサ222が設けられた測定配管210と、測定配管210に薬剤を供給する薬剤供給部250と、第1の冷却水循環装置110Aから冷却水を測定配管210に導入し、測定配管210から排出された冷却水を第1の冷却水循環装置110Aに再導入する第1制御状態と、第2の冷却水循環装置110Bから冷却水を測定配管210に導入し、測定配管210から排出された冷却水を第2の冷却水循環装置110Bに再導入する第2制御状態とを切り換える切換制御部290と、蛍光センサ220およびORPセンサ222のうちいずれか一方または両方の測定結果に基づいて、薬剤供給部250が供給する薬剤の量を制御する供給制御部292と、を備える。【選択図】図1 |
