Recycling water recycling facility and recycling water recycling method

摘要

Problem to be solved: to provide an efficient circulation water reuse facility and a recycling method of circulating water which do not require an excessive pump for the ability to send circulating water to maintain the minimum flow rate when the consumption of circulating water decreases.Recycling water recycling facilitiesThe first channel isLiquid feed pumpA first pipe connecting the first tank and the liquid feed pumpConnecting the process using the feed pump and circulating waterHaving a second pipe comprising a flowmeterAs the second channelHaving a third piping comprising a regulating valve branched from the second piping and returning to the first vesselWhen the flow rate of the flowmeter is less than the first reference value, the opening of the regulating valve is increased so that the difference is reduced.When the first reference value is exceeded, the opening degree of the regulating valve is reduced.Diagram
