Embodiment

[0051] Hereinafter, specific embodiments of the present invention will be described in detail according to the accompanying drawings. figure 1 It is an explanatory diagram showing the first embodiment of the present invention in general.

[0052] exist figure 1 Among them, the water softening device according to the present invention, as the basic structure of the water softener 1, is equipped with a resin cartridge 2 filled with an ion exchange resin (not shown in the figure) and a control valve 3. The control valve 3 is connected to a water supply line 4 for supplying water to the control valve 3 and a treated water line 5 for supplying softened water treated treated water to a soft water tank (not shown). In addition, a brine tank 6 for storing brine for regenerating the ion exchange resin is connected to the control valve 3 through a brine line 7 . The brine line 7 is provided with a device 8 for detecting the concentration of brine supplied from the brine tank 6 into th...

Abstract

The invention provides a water softening device and its regeneration controlling method capable of detecting the hardness of the supply water to be softened with the large of time and controlling regeneration timing based on the detected value. The water softening device is provided with an inlet water hardness measuring means 10 for measuring the hardness of supply water to the water softener 1, a treated water quantity measuring means 11 for measuring the flow rate of treated water after passing through the water softener 1, a salt water concentration detecting means 8 for detecting the salt water concentration at regeneration and a salt water consumption detecting means 9 for detecting the salt water consumption at regeneration. Further, a hardness overlooking detecting means 12 which measures the hardness of water which passed through the water softener 1 and detects the overlooking of hardness is provided.

Description

[Technical field] [0001] The invention relates to a softening water device and a regeneration control method for forming soft water by performing ion exchange treatment on raw water containing hardness components. [Background technique] [0002] It is well known that a device for removing the hardness component contained in the supply water is connected to the water supply line to the heating and cooling equipment such as boilers, water heaters, and coolers, since it is necessary to prevent scale from adhering to the heating and cooling equipment. Among them, the use of An automatic regeneration type water softener in which the hardness component is removed by an ion exchange resin is widely used. This water softener uses Na + Type ion exchange resin that replaces the hardness component Ca contained in water 2+ or Mg 2+ and other metal cations to remove hardness components. Furthermore, in the case where the ion exchange resin is saturated with cations and loses its abil...
