The utilization rate of the brine is actually the utilization rate of sodium ions in the brine, in the regeneration and recovery process, the sodium ions need to be exchanged with calcium and magnesium ions adsorbed in the soft water cavity 201, if the concentration of the calcium and magnesium ions in the soft water cavity 201 is too high, the exchange is weakened, more sodium ions in the brine are discharged without being exchanged, and at the moment, the utilization rate of the brine is low.

Alternatively, the first switch member 120 opens only one of the brine passages 111 at a time and closes the other brine passages 111.

In one embodiment, as shown in fig. 1 and 2, the at least two brine channels 111 can be divided into a first channel 111a and a second channel 111b, each of the first channel 111a and the second channel 111b includes at least one brine channel 111, the first switch 120 has a first position and a second position, when the first switch 120 moves to the first position, the first switch 120 opens the first channel 111a and closes the rest of the brine channels, and when the first switch 120 moves to the second position, the first switch opens the second channel 111b and closes the rest of the brine channels.

The raw water in the first water inlet channel 113 or the second water inlet channel 114 can be mixed with the salt solution fed by the salt absorption channel 112 to form salt solution for regeneration and recovery, as shown in fig. 2, when the first passage 111a is closed by the first switching member 120, the first water inlet channel 113 communicated with the first passage 111a cannot be continuously fed, and at this time, the raw water passes through the second water inlet channel 114 and is mixed with the salt solution fed by the salt absorption channel 112 to form salt solution to flow into the second passage 111b, similarly, as shown in fig. 1, when the second passage 111b is closed by the first switching member 120, the raw water passes through the first water inlet channel 113 and is mixed with the salt solution fed by the salt absorption channel 112 to form salt solution to flow into the first passage 111a, because the flow rates of the first water inlet channel 113 and the second water inlet channel 114 are different, the concentration of the salt solution formed after being mixed with the salt solution fed by the salt absorption channel 112 is also different, and different salt solution channels 111 can be switched according to the utilization rate, saline water with different concentrations is fed into the soft water cavity 201 to improve the utilization rate of the saline water.

Optionally, one of the first and

second passages

111a and 111b outputs low concentration brine, and the other outputs high concentration brine, when the utilization rate of brine is low, if the brine with lower concentration is initially introduced, the exchange can be enhanced by switching to the other brine passage 111 to input brine with higher concentration into the soft water cavity 201; or if the higher-concentration brine is initially introduced, the lower-concentration brine can be input into the soft water cavity 201 by switching to the other brine passage 111 to dilute the calcium-magnesium ion concentration in the soft water cavity 201, and then the higher-concentration brine is switched back again, so that the higher-concentration brine can have a better exchange effect again, and the regeneration recovery effect can be improved in the above manner.

Because the internal diameter of first end 132a is greater than the external diameter of first inner tube 131, first intercommunication portion 113a wholly is located inhales salt passageway 112, then first drainage clearance 133 is cyclic annularly, can be the cyclic annular first intercommunication portion 113a of inhaling with the salt solution that inhales in the salt passageway 112, consequently, it is better to the suction effect of salt solution, the internal diameter of second end 132b reduces along the direction that is close to first passageway 111a gradually, the direction that makes salt solution get into first intercommunication portion 113a is certain contained angle with the flow direction of raw water, it is more abundant to make raw water and salt solution mix, form the salt solution of misce bene.
