Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
The invention provides a sodium hypochlorite generator.
The electrode assembly and the sodium hypochlorite generator of the present invention will be described with reference to fig. 1 to 3.
Referring to fig. 1 and 2, in one embodiment, the electrode assembly 1 of the present invention comprises a first electrode 101 and a second electrode 102, wherein the first electrode 101 and the second electrode 102 are flat sheet-like structures.
The first electrode 101 may be in electrical communication with a positive electrode of a power supply unit (to be described later), and the second electrode 102 may be in electrical communication with a negative electrode of the power supply unit. Thus, the electrode assembly 1 may form an electrolysis circuit.
Further, the first electrode 101 may include a plurality of first arms 1011, and similarly, the second electrode 102 may include a plurality of second arms 1021. In addition, the first arm 1011 and the second arm 1021 can be staggered, so that the effective electrode area of the first electrode and the second electrode is increased, and the electrolysis efficiency is improved.
Preferably, the first electrode 101 and the second electrode 102 are made of a titanium material, and the surface is provided with ruthenium iridium plating or platinum gold plating.
Referring to fig. 1 and 2, in an embodiment, the first electrode 101 may further include a first stem arm 1012, and the plurality of first branch arms 1011 are disposed on the first stem arm 1012 at intervals. Similarly, the second electrode 102 may further include a second stem arm 1022, and the plurality of second arms 1021 are arranged at intervals on the second stem arm 1022. Thus, the first arms 1011 and the second arms 1021 arranged at intervals can be staggered with each other.
Referring to FIG. 1, in one embodiment, the first arms 1011 are disposed on the same side of the first backbone arm 1012, and similarly, the second arms 1021 are disposed on the same side of the second backbone arm 1022. Also, the first electrode 101 and the second electrode 102 are disposed to intersect, so that the plurality of first arms 1011 and the plurality of second arms 1021 can be staggered.
Referring to fig. 2, in another embodiment, a plurality of first arms 1011 are disposed on both sides of the first backbone arm 1012, and similarly, a plurality of second arms 1021 are disposed on both sides of the second backbone arm 1022. Also, the first electrode 101 and the second electrode 102 are disposed to intersect, so that the plurality of first arms 1011 and the plurality of second arms 1021 can be staggered.
Preferably, the plurality of first leg arms 1011 may be bent toward the first stem arm 1012 to form a semi-circular arm. Similarly, the second plurality of arms 1021 may be curved toward the second spine arm 1022 to form a semi-circular arm. Thus, the plurality of first arms 1011 and the plurality of second arms 1021 can be staggered and wrapped around each other, thereby further increasing the effective electrode area of the first electrode 101 and the second electrode 102.
Referring to fig. 1 and 2, in one embodiment, the first electrode 101 and the second electrode 102 are provided with fixing holes 103, respectively. The fixing hole 103 is used for a wire (not shown) to pass through, and the wire can be further connected to a power supply unit. Thus, the first electrode 101 can be electrically connected to the positive electrode of the power feeding unit, and the second electrode 102 can be electrically connected to the negative electrode of the power feeding unit.
Referring to figure 3, in one embodiment, the sodium hypochlorite generator of the invention comprises an electrode assembly 1 and a cup 2 of any of the embodiments described above. Wherein, the cup body 2 is used for containing saline solution, and the electrode component 1 is arranged in the cup body 2.
Preferably, the electrode assembly 1 is disposed at a low water level of the cup body 2 so that the saline solution can completely soak the electrode assembly 1. Thus, chlorine gas (to be described later) generated by the electrolysis reaction can be sufficiently mixed with the salt solution to react, and the utilization rate of the electrode assembly can be improved.
Further, a power supply unit (not shown) is provided on the control unit 3, and a positive electrode and a negative electrode of the power supply unit are connected to the electrode assembly 1, respectively, so that the electrode assembly 1 forms an electrolysis circuit.
Thus, when the saline solution is injected into the cup body 2, chlorine ions in the solution are electrolyzed at the anode of the electrode assembly 1 to generate chlorine gas, and hydrogen ions are electrolyzed at the cathode of the electrode assembly 1 to generate hydrogen gas. Chlorine is dissolved in salt solution and reacts to generate sodium hypochlorite. The chemical reaction equation is as follows:
anode: 2Cl--2e→Cl2↑
Anode: 2H6++2e→H2↑
And (3) hydrolysis reaction: cl2+H2O→HClO+HCl
And (3) total reaction: NaCl + H2O＝NaClO+H2↑
Preferably, the control unit 3 may control the power supply voltage, the power supply current and the power supply time of the power supply unit to generate sodium hypochlorite solutions of different concentrations.
The sodium hypochlorite generator can generate sodium hypochlorite by applying voltage and current to the electrode group to electrolyze a salt solution by the electrode group. And sodium hypochlorite solutions with different concentrations can be generated by controlling parameters of voltage and current applied to the electrode group so as to meet different use requirements of users.
Meanwhile, the sodium hypochlorite generator can be used for preparing sodium hypochlorite at any time without storing the sodium hypochlorite. And the sodium hypochlorite is safe to prepare, has no other unknown chemical impurity residues, and is harmless to human bodies. The sodium hypochlorite aqueous solution can meet the requirements of body disinfection, kitchen disinfection, vegetable and fruit disinfection, clothes disinfection and the like. Meanwhile, the sodium hypochlorite aqueous solution can also be used for disinfection of nonmetal houses and floors and spray disinfection and sterilization of household daily environments.
During the actual use of the generator, scale may be generated on the first electrode 101 and the second electrode 102, which affects the electrolysis efficiency. Further, the control unit 3 may periodically switch the positive electrode and the negative electrode of the power supply unit, and adjust the cathode-anode characteristics of the first electrode 101 and the second electrode 102, that is, the first electrode 101 is electrically connected to the negative electrode of the power supply unit, and the second electrode 102 is electrically connected to the positive electrode of the power supply unit. Thus, the scale formed on the first electrode 101 and the second electrode 102 automatically falls off and is washed away by the water flow. Therefore, the influence of the water scale on the electrolysis efficiency can be effectively relieved.
In one embodiment, the control unit 3 is connected to a control panel (not shown). The control panel can be used for interacting with a user, and the user can set parameters of power supply voltage, power supply current and power supply time through the control panel. The user can also manipulate the control unit 3 to switch the positive and negative poles of the power supply unit through the control panel.
In one embodiment, the cup body 2 may be provided with a water inlet 201 and a water outlet 202, so that the saline solution can be injected into the cup body 2 from the water inlet 201, and the sodium hypochlorite solution (to be described later) is poured out from the water outlet 201 after the sodium hypochlorite solution is generated. Of course, it is also possible to provide only one water inlet for both filling and pouring out the solution.
Preferably, a cap 203 may be provided on the water inlet 201 to open and close the water inlet 201 to prevent dust from entering the cup body 2.
Preferably, the cup body 2 may be provided with a handle 204 to facilitate access to the sodium hypochlorite generator.
It should be noted that the directions "front", "rear", "upper", "lower", and the like are provided for convenience of description, and do not necessarily correspond to the front, rear, upper, and lower in space in actual operation.
In the experiment, the cup body is set to be 2.3L, can contain saline solution 2.0L, and the electrode group selects spiral electrode, and single electrode area is 40cm2, and saline solution concentration is 0.5%, tests show that effective residual chlorine content and bactericidal effect see the following table:
through above-mentioned embodiment, we can conclude, common escherichia coli and staphylococcus aureus can effectively be killed to the hypochlorite generator, can effectively protect user's health safety, have fine practical value to the user.
