In some embodiments, the electrolytic oxygen removal device 40 can also include a reactor 100 and at least one electrolytic oxygen removal unit 200. One side of the reactor 100 forms at least one reaction space 110 which is open towards the front, and the electrolytic oxygen removal units 200 are correspondingly arranged in the reaction space 110 one by one and used for consuming oxygen outside the electrolytic oxygen removal device 40 through electrochemical reaction under the action of electrolytic voltage; wherein each electrolytic oxygen-scavenging unit 200 further comprises an anode plate 210, the anode plate 210 having a main body plate 212, the main body plate 212 being fixed to the rear wall 110a of the reaction space 110.
The reactor 100 may be flat with a wider surface recessed to form one or more reaction spaces 110, and the reaction spaces 110 may be used to contain an electrolyte (e.g., a sodium hydroxide solution, etc.) for an electrolysis reaction.
Referring to fig. 3, in some further embodiments, each electrolytic oxygen removal unit 200 may further include a cathode membrane assembly 220, the cathode membrane assembly 220 being disposed at an opening of the reaction space 110 spaced apart from the body plate 212 to enclose the reaction space 110.
The cathode membrane assembly 220 serves to consume oxygen through electrochemical reaction under the action of an electrolysis voltage. The anode plate 210 serves to supply a reactant (e.g., electrons) to the cathode membrane assembly 220 through an electrochemical reaction under the action of an electrolysis voltage and generate oxygen.
Under power-on conditions, oxygen in the air may undergo a reduction reaction at the cathode membrane assembly 220, namely: o is 2 +2H 2 O+4e - →4OH - . OH-generated from the cathode membrane assembly 220 may undergo an oxidation reaction at the anode plate 210 and generate oxygen, that is: 4OH - →O 2 +2H 2 O+4e - 。
In addition, utility model people realize: a certain distance needs to be firmly maintained between the cathode membrane assembly 220 and the main plate 212 of the anode plate 210 to avoid the reaction efficiency from being low due to an excessively large distance and to avoid the reaction process from being affected by the oxygen generated by the anode plate 210 being unable to be discharged in time due to an excessively small distance.
In this embodiment, since the main body plate 212 of the anode plate 210 is directly fixed to the rear wall 110a of the reaction space 110, that is, the main body plate 212 of the anode plate 210 is in a stable state with respect to the position of the entire reaction space 110, and when the cathode membrane module 220 is installed at the opening of the reaction space 110, the interval therebetween forms a stable interval, and this way, the parts for installing the anode plate 210 in the reaction space 110 are omitted, the reaction space 110 is expanded, and the assembly process is simplified.
Referring to fig. 5 and 6, in some embodiments, the anode plate 210 may be formed by integral injection molding with the reactor 100, so that the main plate 212 of the anode plate 210 is firmly fixed on the rear wall 110a of the reaction space 110, and the production efficiency is improved.
Specifically, a clamping wall 112 extending along a circumferential direction thereof is formed in the reaction space 110, and the clamping wall 112 is used to clamp an edge of the main body plate 212 in cooperation with the rear wall 110a of the reaction space 110 to fix the main body plate 212 such that a central portion of the main body plate 212 is exposed to the reaction space 110.
During injection molding, an injection mold is first manufactured according to the shape of the reactor 100, then the anode plate 210 is fixed at the position of the rear wall 110a of the reactor 100, finally, liquid plastic material (such as polypropylene and the like) is injected into the injection mold, and after cooling and shaping, the assembly formed by the anode plate 210 and the reactor 100 is ejected out of the mold.
It should be noted that, in designing the injection mold, it is also considered to design the clamping wall 112 at the rear wall 110a of the reaction space 110 so that the finally formed reactor 100 can be stably wrapped around the body plate 212 by the clamping wall 112.
Further, the clamping wall 112 extends in a circumferential direction within the reaction space 110, i.e., the clamping wall 112 may extend along the rear wall 110a of the reaction space 110. In some embodiments, the width of the retaining wall 112 may be set between 3cm and 15cm, such as 3cm, 10cm, 15cm, etc.
By the above definition, not only the clamping wall 112 can be matched with the rear wall 110a of the reactor 100 to fix the main body plate 212 of the anode plate 210, but also the clamping wall 112 does not occupy too large area of the main body plate 212, so that the exposed main body plate 212 is larger to ensure the electrolysis efficiency.
Referring to fig. 3, 5 and 6, the anode plate 210 may further include an anode electrical tab 214, and the anode electrical tab 214 is formed at a top edge of the body plate 212 and protrudes from the reaction space 110 to facilitate connection of an external power source.
Specifically, the main body plate 212 of the anode plate 210 may be integrally formed with an anode electrical tab 214, and the anode electrical tab 214 is formed on the top of the main body plate 212, which extends out from the reaction space 110 of the reactor 100 and is connected to the positive electrode of the external power source, so that the anode plate 210 is positively charged and an oxidation reaction occurs.
Since the main body plate 212 of the anode plate 210 is wrapped at the rear wall 110a of the reaction space 110 and the anode electrical tab 214 is formed at the top edge of the main body plate 212, a partial section of the anode electrical tab 214 can also be injection molded into the reactor 100 together during injection molding, and only the end thereof is exposed out of the reactor 100. Therefore, the anode plate 210 can be conveniently powered on, the anode connecting piece 214 can be ensured to be in a stable state, and the influence on the normal power supply of the anode plate 210 caused by factors such as shaking is avoided.
Referring to fig. 7, fig. 7 is a schematic view of an anode plate 210 in an electrolytic oxygen removal device 40 according to an embodiment of the present invention. Further, the anode contact 214 may further include a first section 214a and a second section 214b, a first end of the first section 214a is formed at a top edge of the body plate 212 and extends upward to the inside of the reactor 100, and a first end of the second section 214b is formed at a second end of the first section 214a and extends forward such that the second end thereof protrudes from the inside of the reactor 100.
Referring to fig. 5, the anode electrical connection tab 214 is formed on the top edge of the body plate 212 and then extends upward, extends into the interior of the reactor 100, and then extends forward from the interior of the reactor 100. Compared with the scheme of directly penetrating out of the clamping wall 112, the mode fully utilizes the advantage of injection molding, the anode electric connecting piece 214 is fixed by the reactor 100 with larger thickness (the first section 214a penetrates upwards into the interior of the reactor 100), and the anode electric connecting piece 214 is ensured to be fixed more stably.
Referring to fig. 5 and 7, further, the first section 214a and/or the second section 214b of the anode electrical tab 214 may also be wave-shaped, and fig. 5 shows that the first section 214a is wave-shaped. This is advantageous for obtaining a larger contact area between the anode electrical connecting piece 214 and the reactor 100 during injection molding, and further ensuring that the anode electrical connecting piece 214 is more stably fixed.
In summary, the electrolytic oxygen removal device 40 of the present embodiment provides a technical solution for fixing the reactor 100 and the anode plate 210 by an integral injection molding. In this embodiment, the clamping wall 112 and the rear wall 110a of the reaction space 110 are used to clamp the main plate 212 of the anode plate 210 by injection molding, and the anode contact piece 214 of the anode plate 210 is also fixed to the reactor 100.
The electrolytic oxygen removal device 40 adopting the mode not only can conveniently fix the anode plate 210 and the reactor 100, but also can eliminate other parts for fixing the anode plate 210, simplify the production process, improve the production efficiency and facilitate the batch production.
