As is well known, water supply lines to cooling and heating equipment such as boilers, water heaters, and coolers are equipped with devices to remove hardness contained in the water in order to prevent scale buildup within the cooling and heating equipment. Among them, automatic regeneration water softeners that use ion exchange resin to remove hardness are widely used. This type of water softener uses Na + type ion exchange resin to replace metal cations such as Ca 2+ or Mg 2+ contained in water with Na + to remove hardness. When the resin is replaced with cations and becomes saturated and loses its ability to remove hardness, the ability is restored by reacting with salt water.

る。 By the way, in order to perform playback operations efficiently,
Detects the degree of saturation of the ion exchange resin and supplies the minimum amount of regeneration salt water according to the condition.
It is desirable to perform the regeneration operation at an appropriate timing depending on the degree of saturation. In this case, the method for detecting the degree of saturation of the ion exchange resin is to measure the amount of raw water flowing through the ion exchange resin layer (water flow rate).
There is a method of calculating this value from the amount of hardness contained in the raw water (usually approximately constant). When regeneration is performed using such a flow rate regeneration method, compared to a timer method that performs regeneration at fixed intervals regardless of the water flow rate, it is possible to save the amount of regeneration salt water used and reduce running costs. There is an effect.

However, when using the flow rate regeneration method, if the flowmeter that measures the amount of water passing through malfunctions, the amount of water passing through cannot be integrated, and the ion exchange resin is incorrectly assumed to be in an unsaturated state when it is actually saturated. If the hardness is detected, the regeneration operation may be delayed and the hardness may flow out. If this water is used in a boiler, scale will adhere to the inside of the can, causing overheating and damage to the can.

In view of the above-mentioned problems, this invention combines a flow rate regeneration method and a timer method to ensure that the water softener can regenerate even if the flow meter fails. The flow meter calculates the amount of water flowing through the water softener using a flow meter, and performs a regeneration operation of the water softener when the integrated value reaches a predetermined value, and a failure detection means for the flow meter. The water softener is characterized by including an operation of regenerating the water softener when a predetermined time has elapsed from the previous regeneration operation using a timer in the event of a failure.

るようになつている。 In the figure, 1 is a water softener, which has a resin cylinder 11 and a control valve 12. The ion exchange resin in the resin cylinder 11 removes hardness in raw water, softens the water, and sends it to the water softener tank 5. ing. that time,
When the ion exchange resin becomes saturated, the control valve 12 switches the flow path configuration to suck salt water into the resin cylinder 11, thereby performing a regeneration operation to regenerate the capacity of the ion exchange resin. 3 is a flow meter that measures the amount of water flowing and sends the detection signal to the totalizer 6. When the integrated value of the amount of water flowing reaches a predetermined value, the regeneration controller 7
A reproduction signal is output to the control valve 12.

A discriminator 9 compares and discriminates the signal from the controller 8 that controls the supply/stop of soft water to the soft water tank 5 with the signal from the flow meter 3, and the flow meter 3 indicates normal status when soft water is supplied/stopped. This is to determine whether a certain detection signal is being output. Reference numeral 10 indicates an electric valve inserted into the water flow line, and reference numeral 13 indicates a water level sensor for detecting the water level in the soft water tank 5.

ある。 In addition, a switch that operates above a certain flow rate is installed in the water flow line, or a means is installed to detect the pressure difference in the water flow line before and after the water softener, and these detection signals are compared with the signal from the flow meter. , it may be determined whether a normal detection signal is output from the flowmeter depending on the presence or absence of water flow. It is also possible to provide a spare flowmeter and determine that the flowmeter is malfunctioning when there is a large difference between the measured values of the two flowmeters.

つている。 4 is a timer which starts counting the reproduction signal from the reproduction controller 7 as a reset signal, and sends a signal to that effect to the reproduction controller 7 when a predetermined time has elapsed. However, a relay contact 14 is inserted between the timer 4 and the regeneration controller 7, and the relay contact closes only when a flowmeter failure signal is received from the failure detection means 2. The regeneration controller 7 receives the output signal of the timer 4 and outputs a regeneration signal only when the flowmeter fails.

Clear the value of totalizer 6. If the failure detection means 2 detects that the flowmeter 3 has failed, the relay contact 14 is closed to switch to the timer system, and the regeneration operation is performed when a predetermined period of time has elapsed since the previous regeneration operation.

This invention has the above-mentioned configuration, and combines the flow rate regeneration method and the timer method. Normally, the flow rate regeneration method is used to perform the regeneration operation of the water softener, but when the flowmeter malfunctions, the water softener is switched to the timer method for regeneration. Since the water softener is configured to operate, even if the flow meter fails, the water softener can be regenerated reliably, making it possible to perform extremely safe regeneration control of the water softener without leaking hardness. Moreover, since the flow rate regeneration method is normally adopted, the amount of regeneration salt water used can be saved and running costs can be reduced.
