Abstract:
1. A carbonate spring producing system which dissolves a carbonic acid gas in hot water to produce carbonate springs, the carbonate spring producing system characterized by including: carbonic acid gas supply means; a control valve which controls a flow rate of the carbonic acid gas; hot water supply means; a carbonic acid gas dissolver which is connected to the carbonic acid gas supply means and connected to the hot water supply means; a gas-liquid separator which is connected on a downstream side of the carbonic acid gas dissolver; an un-dissolved carbonic acid gas lead-out pipe which is connected on an upstream side of the carbonic acid gas dissolver while connected to the gas-liquid separator; a liquid lead-out pipe which is connected to the gas-liquid separator; detection means for measuring a liquid level of the gas-liquid separator, flow rate control means for controlling the flow rate of the supplied carbonic acid gas and the flow rate of the un-dissolved carbonic acid gas based on the liquid level of the gas-liquid separator; and gas flow rate control means for measuring a rate at which the liquid level is lowered in the gas-liquid separator with a device, the gas flow rate control means computing a carbonic acid gas concentration in the hot water to control the flow rate of the supplied carbonic acid gas.
