Description

TECHNICAL FIELD

[0001] The utility model relates to brine deployment equipment technical field, especially in an online salt system. BACKGROUND

[0002] The sodium hypochlorite generator is a kind of equipment for generating sodium hypochlorite (NaClO) solution by electrolyzing brine (NaCl solution), and is widely used in water treatment and disinfection and sterilization. In the working process of the sodium hypochlorite generator, the accuracy, stability and hardness of the brine concentration used directly affect the concentration and stability of the sodium hypochlorite generated by the sodium hypochlorite generator. If the brine concentration is too high, it will cause the sodium hypochlorite generator to consume too much salt, increasing the production cost. If the brine concentration is too low, it will cause the electrolysis voltage to be too high and the effective chlorine concentration of sodium hypochlorite to be reduced, and the yield to be reduced. If the hardness of the brine is too high, the electrodes of the sodium hypochlorite generator will be quickly scaled, not only increasing the energy consumption and reducing the yield, but also damaging the electrode coating, and even causing the electrode to be scrapped.

[0003] The traditional salt deployment system has unstable brine concentration and easy interruption of supply, and the softener needs to be manually supplemented with salt frequently according to the consumption of regenerated salt. If the supplement is not timely, the softener will fail to regenerate and cause the hardness of the configured brine to exceed the standard. The instability of brine concentration, hardness and supply will lead to unstable sodium hypochlorite preparation efficiency and reduced service life of the system equipment. In order to ensure the disinfection effect, the entire disinfection system needs to be frequently adjusted and maintained, greatly increasing the operation cost.

[0004] Therefore, in view of the deficiencies of the prior art, it is necessary to design an online salt deployment system to solve the above problems.

[0032] Example:

[0033] like Figure 1 As shown, this utility model discloses an online salt preparation system, including two water softeners 1, a concentrated brine tank 2, a salt preparation tank 3, and a finished brine tank 4. The inlet pipes of both water softeners 1 are connected to the raw water source 100, which provides raw water to the water softeners 1. The brine suction port of the water softener 1 is connected to the concentrated brine tank 2 through a pipe. It should be noted that the water softener 1 can be connected to the concentrated brine tank 2 through a separate pipe or share a single pipe. The soft water outlet of water softener 1 is connected to the soft water inlet of brine tank 3 through a pipe. A solenoid valve 5 is installed on the outlet pipe of water softener 1. The outlet pipe of concentrated brine tank 2 is connected to the suction port of concentrated brine lift pump 6. The discharge port of concentrated brine lift pump 6 is connected to the brine inlet of brine tank 3 through a pipe.

[0036] As Figure 1 shown, in order to further ensure the continuous supply of brine, the second liquid level meter 41 is arranged in the finished brine pool 4, the second liquid level meter 41 is electrically connected with the controller, the liquid surface in the finished brine pool 4 is adjusted through the second liquid level meter 41, when the liquid surface is lower than the set value, a signal is fed back to the controller, the controller controls the salt mixing of the salt mixing pool 3 and the brine delivery of the salt mixing pool lifting pump 7 to the finished brine pool 4.

[0037] As Figure 1 shown, in order to further ensure the continuous supply of brine, the liquid inlet of the concentrated brine pool 2 is communicated with the concentrated brine source 200 through a pipeline, the concentrated brine in the concentrated brine pool 2 can be supplemented at any time.

[0038] As Figure 1As shown, the liquid outlet of the finished brine tank 4 is communicated with the sodium hypochlorite generator through a pipeline, so as to ensure the accuracy and continuity of the brine supply to the sodium hypochlorite generator, thereby improving the production of sodium hypochlorite and reducing the production cost.
