DESCALING AGENT SUPPLY DEVICE
To provide a descaling agent supply device capable of inhibiting a descaling agent from remaining in a nozzle and a washing water flow passage after removing scale accumulated in the nozzle and the washing water flow passage.SOLUTION: A descaling agent supply device comprises a control unit that performs: on a feed water valve, pump, and flow rate sensor, control of switching the feed water valve into a state capable of supplying washing water to a washing water flow passage concurrently with driving the pump to start supply of the washing water to the washing water flow passage and starting detection of a flow rate of the washing water in the washing water flow passage using the flow rate sensor; and, after a predetermined period of time, on the feed water valve and flow rate sensor, control of switching the feed water valve into a state of stopping supply of washing water to the washing water flow passage concurrently with flow rate detection control of detecting, using the flow rate sensor, the flow rate in the washing water flow passage becoming equal to or lower than a predetermined value.SELECTED DRAWING: Figure 10
【課題】ノズル及び洗浄水流路に溜まったスケールを除去した後に、デスケール剤がノズル及び洗浄水流路に残ることを抑えることが可能なデスケール剤の供給装置を提供すること。【解決手段】制御部は、給水弁を切り換えて洗浄水を洗浄水流路に供給可能な状態とすると同時に、ポンプを駆動させて、洗浄水を洗浄水流路に供給し始め、且つ、流量センサにより洗浄水流路における洗浄水の流量を検知し始める制御を、給水弁、ポンプ、及び、流量センサに対して行い、所定時間後に、給水弁を切り換えて洗浄水を洗浄水流路に対して供給停止状態とすると同時に、洗浄水流路における流量が所定の値以下になったことを流量センサによって検知する流量検知制御を、給水弁及び流量センサに対して行う、デスケール剤の供給装置である。【選択図】図10
