水を吸入する方法が公知である。[Prior art] In conventional salt water control devices, the interval from the previous regeneration to the next regeneration is determined based on the properties of the raw water to be regenerated, and the hardness is calculated along with the amount of water flow during that time, and the amount of salt water is adjusted accordingly. The amount of salt water (that is, the amount of salt) to be used for one regeneration is determined in advance with a safety factor in mind, and the regeneration time is calculated. In addition, as a method of sucking salt water during regeneration, the nozzle 7 at the tip of the raw water line 7
A method is known in which saline water is sucked from a saline line by means of the ejector action of A.

生を終了するといつたことが問題となる。 Figure 3 shows the relationship between the amount of salt water suction during regeneration, the instantaneous flow rate of salt water detected by a flow meter inserted in the water collection pipe, and the required salt water suction time.The vertical axis on the left shows the amount of salt water suction. The vertical axis on the right side shows the required salt water suction time, and the horizontal axis shows the instantaneous salt water flow rate detected by the flow meter. Point a in the figure indicates that if the flow rate is less than or equal to a, the nozzle 7A at the tip of the raw water line 7 does not perform the ejector action, so the salt water is not sucked in, and if the flow rate is greater than or equal to a, the nozzle acts as an ejector. This indicates that salt water is sucked in. In other words, when using the conventional method, as long as the flow rate of raw water is equal to or greater than a, even if the flow rate of raw water changes during regeneration, regeneration is only performed steadily within the pre-calculated regeneration time.
The problem is that the regeneration ends before the amount of salt water necessary for the regeneration is completely supplied.

The control valve connected to the resin cylinder is connected to a salt water line 6, a raw water line 7, a soft water line 8, and a drainage line 9. When water is flowing, raw water flows from the upper part of the resin cylinder under raw water pressure, and the water flows through the resin cylinder. The water is transferred from the water collection pipe to the soft water line. During regeneration, as shown in FIG. 2, salt water is sucked through the salt water line according to the raw water flow rate by ejector action via a salt water suction nozzle 7A provided at the lead-in end of the raw water line 7. The inhaled salt water regenerates the ion exchange resin, and at this time, the drain containing the generated hardness is discharged from the drainage line via the water collection pipe and the flow meter 10.

This arithmetic circuit 12 takes into account the hardness of the raw water measured in advance and the interval from one regeneration to the next regeneration, detects the amount of water flowing during this period with the flow meter when water is flowing, and calculates the hardness and the amount of water flowing. The system is configured to calculate the amount of brine required for reasonable regeneration. Further, the arithmetic circuit 13 stores in advance the relationship between the flow rate of salt water and the amount of salt water sucked in, and during regeneration, the flow meter detects the amount of drainage, thereby confirming the actual amount of salt water suction, and the arithmetic circuit 12 The apparatus is configured to receive a signal indicating a set amount of salt water, and when that amount of salt water is reached, to terminate the regeneration and issue a signal.

2, the hardness of the raw water and the interval from one regeneration to the next regeneration are set in advance. During water softening, raw water enters the resin cylinder from the raw water line, comes into contact with the ion exchange resin, is softened, and is transferred from the water collection pipe and flowmeter to the outside of the system through the control valve. The amount of water flowing at this time is detected by a flow meter, and the calculation circuit 1
2 as a signal to set the amount of salt water required for regeneration. The ion exchange resin in the resin cylinder is sequentially converted from Na type to Ca type ion exchange resin from the upstream side by ion exchange. When the regeneration is started according to the interval set in the calculation circuit 12, the amount of salt water set in the calculation circuit 12 is sent to the calculation circuit 13 as a signal. The control valve sucks in salt water, and the salt water that reaches the resin cylinder undergoes ion exchange with Ca type ion exchange resin, and the ion exchange resin is Na
Regenerated into a mold. At this time, the amount of salt water sucked in varies depending on the amount of raw water passing through the nozzle, so the flow meter detects the amount of salt water passing through, and sends the amount of passing salt water as a signal to the calculation circuit 12, which indicates the amount of salt water that has passed through the nozzle. Check the actual amount of salt water suction based on the relationship between the amount and the amount of salt water suction. Drain water containing hardness during regeneration is discharged to the outside of the system through a water collection pipe and a drainage line. When the actual amount of salt water suction confirmed by the calculation circuit 13 reaches the amount of salt water required for regeneration set by the calculation circuit 12, the regeneration is terminated by a signal from the calculation circuit 13. After that, raw water is supplied to the salt water tank from the salt water line, and the raw salt in the salt water tank is dissolved to generate salt water.

る。 Note that when water is flowing, the flow rate is detected by the flowmeter, and the amount of salt water necessary for regeneration is set in accordance with the hardness and the amount of water flowing. At the same time, the time required for regeneration is also set, and the arithmetic circuit 12' is configured so that the control valve performs the regeneration operation within the set time.
By using this, even if the flow meter is malfunctioning, regeneration can be completed after the set time has elapsed.

Therefore, it is possible to check whether the amount of salt water necessary for regeneration is actually being supplied, thereby eliminating the possibility that regeneration is incomplete. Compared to determining the amount of salt water based only on the regeneration time, it is possible to reduce errors by directly measuring the flow rate, allowing the amount of salt water required for regeneration to be used accurately, and eliminating unnecessary amounts of salt. Since there is no need to do this, running costs can be reduced. Furthermore, even if the flow meter is out of order, it is controlled based on time, so it is possible to move on to the next step after the set time has elapsed. Furthermore, by setting the regeneration interval to one day, the capacity of the water softener can be maintained at a high level at the beginning of each day's work.
