Detailed Description
Fig. 1 is a schematic structural view of a gas processing apparatus 200 according to an embodiment of the present invention.
The gas processing apparatus 200 of the present embodiment is used to process a specific gas component in a gas, for example, to increase or decrease the content of the specific gas component. The gas processing device 200 may generally include a multi-faceted electrode.
The gas processing apparatus 200 of the present embodiment processes a specific gas component in a gas by an electrochemical reaction of an electrode.
The multi-faceted electrode has a plurality of segments of plates 222 oriented differently, each segment of plates 222 configured to process a particular gas component in a space toward which it is oriented by an electrochemical reaction. The different orientations of the plurality of segments of plates 222 mean that the plurality of segments of plates 222 are not in the same plane. For example, adjacent plates 222 may be angled or curved so that multiple electrodes may be simultaneously oriented in different spaces and may be simultaneously in airflow communication with different spaces.
Since the gas processing apparatus 200 has the multi-surface electrode, each segment of the electrode plate 222 of the multi-surface electrode can face different spaces and process the specific gas components in the facing spaces, according to the solution of the present embodiment, the specific gas components in the plurality of spaces can be processed by using the same gas processing apparatus 200, which is beneficial to simplifying the architecture of the refrigerator 10 and reducing the manufacturing cost.
In some alternative embodiments, gas treatment device 200 further includes a multi-sided counter electrode having multiple segments of counter plates 242 oriented differently, with one pair of plates 242 opposing one plate 222 to form multiple sets of electrode pairs. That is, each segment of the plate 222 has a counter plate 242 corresponding thereto. In each set of electrode pairs, the plate 222 is opposite in polarity to the counter plate 242, and may be either an anode or a cathode, respectively.
Since each electrode plate 222 has a corresponding counter electrode 242 to form a plurality of electrode pairs, and the two electrodes of each electrode pair respectively perform different electrochemical reactions and obtain different gas conditioning effects, the solution of the present embodiment is advantageous for improving the flexibility of the gas conditioning process of the gas processing apparatus 200.
By arranging the plurality of segments of counter electrode plates 242 and making the plurality of segments of counter electrode plates 242 and the plurality of segments of electrode plates 222 face each other one by one, a plurality of sets of electrode pairs are formed, each set of electrode pairs can independently perform electrochemical reaction, and thus gas components in corresponding spaces can be independently adjusted, so that the gas treatment device 200 can adapt to different gas conditioning requirements of a plurality of spaces, and the universality of the gas treatment device 200 can be improved.
Of course, in alternative embodiments, the polarity of the multi-segment plates 222 of the multi-face electrode may be the same, and the polarity of the multi-segment counter plates 242 of the multi-face counter electrode may be the same, which is beneficial to ensure the consistency of the multi-face electrode and the multi-face counter electrode, and reduce or avoid the occurrence of confusion.
In some alternative embodiments, the multi-faced counter electrode may be changed into a counter electrode with other shapes, for example, a flat plate-shaped counter electrode or a columnar counter electrode, as long as the counter electrode is opposite to each segment of the electrode plate 222 of the multi-faced electrode.
For example, each segment of the multi-surface electrode 222 may be a plate, and the segments of the multi-segment electrode 222 may be bent and connected to form a wave-shaped cut-off surface, and a flat counter electrode may be disposed on the opposite side of the multi-segment electrode 222. For another example, each segment of the plate 222 of the multi-surface electrode may be a plate, and the multiple segments of the plate 222 may be connected end to end in sequence and enclose a closed hollow prism, and at this time, the columnar counter electrode may be disposed inside the hollow prism where the multiple segments of the plate 222 are located. Of course, the shape of the multi-faced electrode and the multi-faced counter electrode is not limited to these examples.
In some alternative embodiments, the multi-faced electrode and the multi-faced counter electrode are selected from either of the anode and the cathode, respectively. That is, the multi-segment plates 222 of the multi-face electrode have the same polarity, and the multi-segment counter plates 242 of the multi-face counter electrode have the same polarity. The polarity of the plate 222 is the polarity of the multi-sided electrode, and the polarity of the counter plate 242 is the polarity of the multi-sided counter electrode. Wherein the cathode is adapted to be connected to a negative pole of a power source and adapted to consume oxygen by performing an electrochemical reaction. The anode is adapted to be connected to a positive electrode of a power source and to provide reactants to the cathode by performing an electrochemical reaction.
For example, the specific gas component of the present embodiment may be oxygen. The oxygen in the air can undergo a reduction reaction at the cathode, i.e.: o is 2 +2H 2 O+4e - →4OH - . OH produced at the cathode - An oxidation reaction may occur at the anode and generate oxygen, i.e.: 4OH - →O 2 +2H 2 O+4e - . Anode is using OH - While the electrochemical reaction takes place, a reactant, e.g. an electron, is also supplied to the cathode - 。
By adopting the structure, the gas treatment device 200 can treat the oxygen in the storage space of the refrigerator 10 so as to comply with the development concept of low-oxygen preservation, prolong the shelf life of food materials such as fruits and vegetables and improve the preservation performance of the refrigerator 10.
Meanwhile, since the anode generates oxygen during the electrochemical reaction, the oxygen can be utilized and, for example, can be delivered to the high oxygen space of the refrigerator 10, which can improve the air conditioning capability of the refrigerator 10, so that a low oxygen fresh-keeping atmosphere and a high oxygen fresh-keeping atmosphere can be created at the same time.
In some embodiments, the electrolysis chamber 230 may be provided with a vent to facilitate the discharge of oxygen generated at the anode. Oxygen generated at the anode may be exhausted through an exhaust port. For example, the exhaust port may be provided on the first or second protective frame 212 or 214, which will be described below, and located directly above the electrolytic chamber 230.
Of course, the above examples of electrochemical reactions and their equations are merely illustrative, and those skilled in the art should be able to easily extend the gas treatment device 200 of the present embodiment to other types of electrochemical reactions and treat specific gas components of other types, such as electrochemical reactions for generating or consuming carbon dioxide, electrochemical reactions for generating or consuming nitrogen, electrochemical reactions for generating or consuming ethylene, etc., and such extensions are all within the scope of the present invention.
Each segment of the plate 222 of the multi-faceted electrode may be a unitary piece or may be a separate piece. When each segment of the plate 222 of the multi-surface electrode is a single piece, the plate-shaped electrode can be bent to form a plurality of segments of plates 222 with different orientations, or the plurality of segments of plates 222 with different orientations can be directly obtained by a forming process. When the plurality of segments of plates 222 are separate pieces, the plurality of segments of plates 222 are spliced to form a multi-face electrode, and a gap may be formed between adjacent plates 222. Each segment of counter plate 242 of the multi-faceted counter electrode may be a unitary piece or may be individually discrete pieces. When each section of the counter electrode 242 of the multi-surface counter electrode is a single piece, the flat-plate-shaped electrode may be bent to form a plurality of sections of counter electrodes 242 with different orientations, or the plurality of sections of counter electrodes 242 with different orientations may be directly obtained by a forming process. When the multi-segment counter electrode plate 242 is a discrete member, the multi-segment counter electrode plate 242 forms a multi-face counter electrode by splicing, and a gap may be formed between adjacent counter electrode plates 242. Here, the "separate members" are members provided independently of each other, and the concept of "integrally formed" as the "one-piece member" is contrary to the concept of "integrally formed".
The pole plates 222 which are separately arranged are adopted to form a multi-surface electrode, the counter pole plates 242 which are separately arranged are adopted to form a multi-surface counter electrode, the pole plates 222 and the positions and the orientations of the counter pole plates 242 can be flexibly arranged, the structure of the gas processing device 200 is diversified and refined, the gas processing device is convenient to perform gas conditioning processing on a plurality of storage spaces with specific spatial layout, a complex bending process or a forming process is not needed, and the gas processing device has the advantage of simple process.
In some alternative embodiments, the multi-segment plate 222 of the multi-face electrode and the multi-segment counter plate 242 of the multi-face counter electrode respectively enclose a hollow prism, such as a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, or the like, preferably a quadrangular prism. The multi-segment plate 222 can treat gas from all sides, which makes the gas treatment device 200 particularly suitable for being mounted to a refrigerator 10 having a large number of storage spaces.
Because the multi-segment electrode plate 222 of the multi-face electrode and the multi-segment counter electrode plate 242 of the multi-face counter electrode respectively enclose the hollow prism, the gas conditioning device has a small volume and a small occupied space, and the gas conditioning device has a high gas conditioning efficiency because a plurality of electrode pairs can simultaneously treat gas in a plurality of different spaces and gas in the same space, so that the gas conditioning device has the advantages of high gas conditioning efficiency and small volume based on the scheme of the embodiment.
In some alternative embodiments, the hollow prism body in which the multi-segment counter plate 242 of the multi-face counter electrode is located is sleeved outside the hollow prism body in which the multi-segment plate 222 of the multi-face electrode is located. The side of the multi-sided electrode facing away from the multi-sided counter electrode forms a gas flow channel 250 for gas to flow through, and gas to be treated can flow through the gas flow channel 250 and participate as a reactant in the electrochemical reaction of the plate 222. Fig. 2 is a schematic structural view of a gas processing apparatus 200 according to another embodiment of the present invention, in which arrows show the flow direction of gas flowing through a gas flow channel 250 formed on one side of a multi-sided electrode facing away from a multi-sided counter electrode, and partial pole plates and counter pole plates are omitted.
At this time, the gas to be treated may flow along the extending direction of the gas flow channel 250, and during the flowing process, the specific gas component in the gas continuously participates in the electrochemical reaction and is consumed, which may make the gas flowing out of the gas flow channel 250 contain very little specific gas component, enhance the gas conditioning effect, reduce the time required for gas conditioning, and reduce the gas flow cycle number. The storage space of the refrigerator 10 and the gas processing device 200 may be configured to accommodate only one or a few air flow cycles.
The side of the multi-faced electrode facing away from the multi-faced electrode also forms a gas flow channel 250 through which the gas flows. The multi-faced electrodes may treat a specific gas component in the gas flowing through or staying in the gas flow channel 250 through an electrochemical reaction.
The gap between the faceted electrode and the faceted counter electrode forms an electrolysis chamber 230 for holding electrolyte. The electrolytic cavity 230 can contain alkaline electrolyte, such as 0.1-8 mol/L NaOH or KOH, and the concentration thereof can be adjusted according to actual needs.
In some alternative embodiments, the gas treatment device 200 further includes a first protective frame 212 and a second protective frame 214. The first protective frame 212 is a hollow prism and is sleeved outside the hollow prism where the multi-segment counter electrode plates 242 of the multi-pair electrodes are located. The second protective frame 214 is also hollow prism-shaped and is sleeved on the inner side or the outer side of the hollow prism where the multi-segment electrode plate 222 of the multi-face electrode is located.
The first and second protective frames 212 and 214 are used to protect the multi-faced electrode and the multi-faced electrode, respectively, which may improve the structural strength of the gas treatment device 200 to some extent and reduce or prevent leakage of the electrolyte. In some further embodiments, the first protective frame 212 may be provided with air holes for allowing air to pass through, so as to avoid completely shielding the multiple counter electrodes and ensure normal gas-adjusting process.
It should be noted that, when the multi-segment plate 222 of the multi-face electrode and the multi-segment counter plate 242 of the multi-face counter electrode are separate pieces, the first protective frame 212 and the second protective frame 214 also perform an integrating function, so that the separately arranged plate 222 and counter plate 242 are assembled into a whole.
Of course, in alternative embodiments, the hollow prism body in which the multi-segment counter plate 242 of the multi-face counter electrode is located may be changed to be sleeved in the hollow prism body in which the multi-segment plate 222 of the multi-face electrode is located. At this time, the multi-surface electrode can obtain a larger area of the electrode plate 222 to increase the electrochemical reaction rate, and a gas flow channel 250 for gas to flow is formed at one side of the multi-surface electrode facing back to the multi-surface counter electrode, and the gas flow channel 250 has a larger gas flow space. When the multi-face electrode is a cathode and is used to remove oxygen, the gas processing device 200 can achieve greater oxygen removal efficiency.
In some alternative embodiments, the multi-faceted electrode treats a particular gas component of the gas flowing or residing in its side facing away from the multi-faceted counter electrode by an electrochemical reaction that provides the reactant to the multi-faceted electrode. The air flow channel 250 enclosed by one side of the multi-surface electrode back to the multi-surface counter electrode is the inner space of the multi-surface electrode.
In other alternative embodiments, the polarity of the multi-sided electrode and the multi-sided counter electrode may be reversed, for example, the multi-sided counter electrode may treat a particular gas component in the gas flowing or retained on the side thereof facing away from the multi-sided electrode by performing an electrochemical reaction that provides a reactant to the multi-sided counter electrode. The air flow channel 250 facing the side of the multi-face electrode facing away from the multi-face electrode is the outer space of the multi-face electrode.
In some alternative embodiments, the gas treatment device 200 may further include a first enclosure 216 and a second enclosure 218.
Wherein the first closing portion 216 closes a gap between the first end of the multi-faced electrode and the first end of the multi-faced counter electrode. The second closure portion 218 closes a gap between the second end of the multi-faceted electrode and the second end of the multi-faceted counter electrode. That is, the first closing part 216 and the second closing part 218 close the gaps between the both ends of the multi-surface electrode and the multi-surface counter electrode, respectively, to seal the electrolytic chamber 230.
In some alternative embodiments, the first and second closure portions 216 and 218 may be in the form of annular cover plates to close the gap between the ends of the multi-faceted electrode and the multi-faceted counter electrode, respectively, and may be attached to the multi-faceted electrode and the multi-faceted counter electrode, respectively, by any means such as riveting, welding, threading, snapping, or bonding.
Fig. 3 is a schematic structural view of the refrigerator 10 according to one embodiment of the present invention. The structure of the refrigerator 10 will be described below taking as an example a case where a specific gas component is oxygen.
The refrigerator 10 may generally include a cabinet 100 and the gas treatment device 200 of any of the above embodiments. In which a storage space is formed in the cabinet 100, for example, the storage space may include a low oxygen space and/or a high oxygen space. The cathode of the gas treatment device 200 may be in gas flow communication with the reduced oxygen space and reduce the oxygen content of the reduced oxygen space through an electrochemical reaction. The anode of the gas treatment device 200 may be in gas flow communication with the high oxygen space and increase the oxygen content of the high oxygen space through an electrochemical reaction.
For example, when the cathode is a multi-faced electrode and the multi-faced electrode is sleeved inside the multi-faced electrode, the two ends of the airflow channel 250 formed at one side of the multi-faced electrode facing away from the multi-faced counter electrode and the low oxygen space may be respectively communicated with the air inlet pipeline and the air return pipeline, so that the airflow communication between the cathode and the low oxygen space may be realized, and the airflow circulation channel may be formed. An airflow actuating device may be connected between the inlet line and the hypoxic space for causing an airflow to be formed from the hypoxic space through the inlet line and towards the cathode, and back to the hypoxic space after flowing through the return air line.
The refrigerator 10 also has an oxygen gas delivery passage communicating the electrolysis chamber 230 with the high oxygen space for delivering the oxygen gas generated at the anode to the high oxygen space. For example, the oxygen delivery passage may have a first end connected to the exhaust port and a second end connected to the high oxygen space.
The gas treatment device 200 may be disposed within a foaming material of the refrigerator 10. The foaming material has a certain reserved space, and the space utilization rate of the refrigerator 10 can be improved by installing the gas treatment device 200 in the reserved space. By means of the heat-insulating environment of the foaming material, the gas processing apparatus 200 can exert high oxygen removal efficiency and oxygen generation efficiency.
Of course, the gas processing device 200 may alternatively be disposed at any suitable location within the enclosure 100, such as within a press compartment, on a duct cover, or within the storage compartment 120, etc. Fig. 3 illustrates the case of being installed in the storage chamber 120 as an example, but the installation position of the gas processing apparatus 200 is not limited thereto.
Because the multi-segment polar plate 222 and the multi-segment counter polar plate 242 respectively enclose a hollow quadrangular prism, and the hollow quadrangular prism at the counter polar plate 242 is sleeved outside the hollow quadrangular prism at the polar plate 222, therefore, the counter polar plates 242 are opposite in pairs, as shown in fig. 3, when the gas treatment device 200 is arranged between two storage spaces arranged side by side, each storage space can be opposite to one pair of polar plates 242 respectively, the unique structure of the gas treatment device 200 can be perfectly matched with the layout structure of the storage compartment 120 of the refrigerator 10, the structure is ingenious, the gas path structure can be favorably reduced, and the space layout of the refrigerator 10 is optimized.
For example, in some alternative embodiments, the first storage space 121 is laterally juxtaposed with the second storage space 122. The hollow quadrangular prism where the counter plate 242 is located is disposed between the first storage space 121 and the second storage space 122, so that the counter plates 242 located at two lateral sides of the hollow quadrangular prism are respectively in air flow communication with the first storage space 121 and the second storage space 122.
Of course, the spatial layout pattern of the refrigerator 10 is not limited thereto. For example, in other alternative embodiments, the first storage space 121 and the second storage space 122 are longitudinally juxtaposed.
