When the water production requirement is to further process the EDI water, the control system 3 controls the electronically controlled three-way valve 14d to connect to the next-level purification device. In the EDI device, the directional migration of ions in the water is realized under the action of the electric field, so as to achieve the deep purification and desalination of water.

reactors

21 and 22 in sequence from upstream to downstream. The additive injection device is provided with two

additive injection parts

23 and 24. The additive from the additive injection part is added to the corresponding reactor to carry out the corresponding reaction to produce the required solution, such as slightly acidic hypochlorous water.

In this embodiment, the hypochlorous acid water generator 2 has two

reactors

21 and 22. The reactor 21 has a parallel phase fluid part 21a, a phase interface reaction part 21b, and a fluid homogenizing part 21d.

Specifically, the parallel phase fluid part 21a is arranged such that the first additive from the first additive injection part, such as sodium hypochlorite, naturally diffuses in the water from the purification device by virtue of its own diffusive force. The parallel phase fluid part 21a may be a section of pipeline without any obstacles inside. In this way, the additive stock solution with high concentration can first diffuse naturally and reduce the concentration, thereby preventing useless reactions. The direction in which the first additive is added to the water forms an oblique angle with the flow direction of the water, and the oblique angle may be any suitable angle, for example, 60 to 110 degrees.

The phase interface reaction part 21b is arranged to enable the solution from the parallel phase fluid part 21a to be sputtered in the phase interface reaction part 21b and has a water inlet and a water outlet. The water inlet of the phase interface reaction part 21b is connected to the water outlet of the parallel phase fluid part 21a. The phase interface reaction part 21b is arranged to promote further diffusion of the additive in the phase interface reaction part. The phase interface reaction part may be a pipeline with interference sheets arranged inside. When the mixed liquid formed by the water and the additive flows through the phase interface reaction part, it will collide with the interference plate, thereby promoting the diffusion of the additive in the water.

The fluid homogenizing part 21d is arranged to be able to homogenize the solution from the phase interface reaction part 21b and has a water inlet and a water outlet, and the water inlet of the fluid homogenizing part is connected with the water outlet of the phase interface reaction part.

As shown in FIG. 1, in this embodiment, a filter 21c is also provided between the phase interface reaction part 21b and the fluid homogenizing part 21d of the reactor 21. The filter 21c can prevent garbage and air, and can also homogenize the solution, and at the same time make molecules from large to small, and can also homogenize the flow rate of the generated water to stabilize it. If necessary, the filter 21c may not be provided. The liquid coming out of the reactor 21 is the first mixed liquid.

Similarly, the reactor 22 has a parallel phase fluid part 22a, a phase interface reaction part 22b, and a fluid homogenizing part 22c. The parallel phase fluid portion 22a of the reactor 22 is arranged to diffuse the second additive (for example, HCl) into another liquid (for example, the first mixed liquid) to form a solution, and has a water inlet and a water outlet. Specifically, the parallel phase fluid part is arranged so that the second additive from the second additive injection part, such as hydrochloric acid, naturally diffuses in the solution from the reactor 21 by virtue of its own diffusion force. The parallel phase fluid part can be a section of pipeline without any obstacles inside. In this way, the additive stock solution with high concentration can first diffuse naturally and reduce the concentration, thereby preventing useless reactions. The direction in which the second additive is added to the first mixed liquid forms an oblique angle with the flow direction of the first mixed liquid, and the oblique angle may be any suitable angle, for example, 60 to 110 degrees.

The phase interface reaction part 22b is arranged to enable the solution from the parallel phase fluid part to be sputtered in the phase interface reaction part and has a water inlet and a water outlet. The water inlet of the phase interface reaction part 22b is connected to the water outlet of the parallel phase fluid part 21a. The phase interface reaction part 22b is arranged to promote further diffusion of the second additive in the phase interface reaction part 22b. The phase interface reaction part 22b may be a pipe in which interference pieces are arranged. When the mixed liquid of water, the first additive and the second additive flows through the phase interface reaction part, it will collide with the interference plate, thereby promoting the diffusion of the additive in the water.

The fluid homogenizing part 22c is arranged to be able to homogenize the solution from the phase interface reaction part 22b and has a water inlet and a water outlet, and the water inlet of the fluid homogenizing part is connected with the water outlet of the phase interface reaction part.

As shown in FIG. 1, in this embodiment, a phase interface reaction part 2d and a jet flow part 2e are sequentially provided between the reactor 21 and the reactor 22. The phase interface reaction part 2d is similar in structure and function to the phase interface reaction part 21b, both of which promote the further diffusion of additives, and can be constituted by a pipe with interfering sheets inside.

The injection stream portion 2e is provided with an additive injection port. The additive from the additive injection part can enter the jet stream part through the additive injection port. The jet stream portion is arranged so that the flow rate of the solution from the previous-stage reactor increases. Thus, the additive, such as hydrochloric acid, can be quickly diluted, so that the additive has little room for reaction with the first additive in the solution of the previous stage reactor, such as sodium hypochlorite. The jet portion 2e may be a section of pipe whose inner diameter changes from large to small. When water flows through the pipe, the speed becomes faster. The jet flow part may also have another structure that can accelerate the water flow.

In some cases, the jet portion 2e may not be provided. If the jet stream part 2e and the reactor 22 are provided at the same time, the additive from the additive injection part is first added to the jet stream part and mixed with the solution from the previous reactor before entering the reactor 22. If only the reactor 22 is provided without the jet stream part, the additive from the additive injection part directly enters the parallel phase fluid part of the reactor 22 and is mixed with the solution from the previous stage reactor.

Corresponding inlets and outlets are provided between the various parts within each reactor and between the reactors. These interconnected inlets and outlets can be separate inlets and outlets, or they can be the same part, that is, the inlet and outlet are actually the same part.
