Description
Technical Field
The invention belongs to the technical field of water treatment equipment, and particularly relates to a wireless sensing device and water softening equipment using the same.
Background
The water softening equipment mainly removes calcium and magnesium ions in water through an ion exchanger to achieve the purpose of reducing the water hardness. When the ion exchange agent is used for the exchange reaction of sodium ions Na +, the method is called a sodium (Na) type ion exchange method. When using the nano-ion exchange method, a certain amount of salt is consumed. When the ion exchange resin exchanges the sodium ions inside, the calcium and magnesium ions in the resin need to be exchanged again by salt, and the process is called regeneration.
The point in time at which the ion exchanger is exhausted and must be regenerated depends on the rated capacity of the water softening device, on the water quality (i.e. raw water hardness) and on the water consumption.
In the conventional water softening plant, the regeneration period is generally controlled by time or flow, and when the water softening plant is used for the set time or flow, the regeneration process is started. However, this method of setting a fixed regeneration cycle ignores the actual use situation of the user and ignores the water quality change at different local times. When the water consumption of a user is increased, the ion exchanger consumes sodium ions in the ion exchanger before the set time of the regeneration period is not reached, hard water cannot be softened, and thus the water used by the user is still hard water which is not subjected to softening treatment; when the water consumption of the user is reduced, even if the sodium ion consumption in the ion exchanger is low after the set regeneration period is reached, the softening treatment can be continued, and the salt is wasted when the regeneration is started.
In addition, the change of water hardness also affects the determination of the regeneration cycle, and if the current water hardness is low, the softening treatment can be continued even if the consumption of sodium ions in the ion exchanger is low after the set regeneration cycle is reached; if the hardness of the current water is high, the ion exchanger consumes the sodium ions inside before the regeneration set period is not reached, the tap water cannot be softened, and the water used by the user is still hard water without being softened. Therefore, the regeneration period of the water softening equipment is realized by means of time control or flow control based on theoretical calculation, but the actual use condition is influenced by a plurality of factors, such as impurities of inlet water, whether the regeneration is sufficient or not, the service life of the ion exchange resin and the like, finally have errors with the theoretical calculation result, and the waste of the regenerant or the insufficient regeneration is caused.
