Detailed Description
Fig. 1 is a schematic block diagram of a gas processing apparatus 200 according to an embodiment of the present invention. The gas processing device 200 can generally include a housing 210, a first electrode plate 220, and a second electrode plate 240. The gas processing apparatus 200 of the present embodiment processes a specific substance component in a gas flowing therethrough by performing an electrochemical reaction, for example, increasing or decreasing the content of the specific substance component.
The housing 210 has an arc-shaped curved surface 212. For example, the arc curved surface 212 may be a curved surface that is arched toward the outside of the case 210, or may be a curved surface that is concave toward the inside of the case 210.
The arc-shaped curved surface 212 is provided with a ventilation area 212a. The gas permeable area 212a allows gas to pass through. The form of the ventilation region 212a is not limited as long as it can perform ventilation. For example, an opening may be directly formed in the arc-shaped curved surface 212, or a hole may be formed in the arc-shaped curved surface 212.
The interior of the housing 210 defines an electrolysis chamber 214 located inside the gas permeable region 212a. The electrolytic chamber 214 is used for containing an electrolyte, so that a first electrode plate 220 and a second electrode plate 240, which will be described below, are immersed in the electrolyte.
The first electrode plate 220 is an arc-shaped curved surface 212 plate adapted to the shape of the arc-shaped curved surface 212, and is disposed at the air permeable area 212a. The first electrode plate 220 is adapted to the shape of the arc-shaped curved surface 212, so that the first electrode plate 220 can be attached to the air permeable area 212a of the arc-shaped curved surface 212. For example, in some embodiments, the arc of the first electrode plate 220 is the same as the arc of the arc-shaped curved surface 212.
In the gas processing apparatus 200 of the present embodiment, since the housing 210 has the arc-shaped curved surface 212, the gas permeable region 212a is opened on the arc-shaped curved surface 212, the first electrode plate 220 is provided as the arc-shaped curved surface 212 matching with the outer shape of the arc-shaped curved surface 212, and the second electrode plate 240 is at least partially provided in the electrolytic chamber 214 in the housing 210, the contact area between the first electrode plate 220 and the gas outside the housing 210 can be increased by using a limited volume, and therefore, the gas processing apparatus 200 has advantages of high gas conditioning efficiency and small volume.
Compared with the straight structure in the prior art, the gas processing apparatus 200 of the present embodiment adds the arc-shaped curved surface 212 structure, and provides the novel gas processing apparatus 200 with unique shape and structure, which breaks through the limitation of the flat structure layout of the refrigerator 10. The arc-shaped curved surface 212 is not only embodied on the electrode plate, but also embodied on the housing 210, so that the gas processing apparatus 200 can make the first electrode plate 220 fully contact with the gas to be processed by virtue of a smaller volume.
In some alternative embodiments, the housing 210 is a hollow sphere with walls defining an arcuate curve 212. That is, the whole housing 210 is a rounded arc-shaped curved surface 212, and the ventilation area 212a can be selectively provided at any position and can occupy a relatively large area, thereby obtaining a relatively large ventilation area.
Since the housing 210 may be in the shape of a hollow sphere, this unique profile makes the gas treatment device 200 suitable for installation in certain specific spaces, such as the pressing compartment 160 of the refrigerator 10 or a duct, etc., which is advantageous to increase the variety of installation locations of the gas treatment device 200.
In some further embodiments, the breathable regions 212a are disposed on a hemispherical surface of the housing 210. That is, the area of the ventilation area 212a does not exceed the hemispherical surface area of the housing 210. In this way, a portion of the spherical surface can contact the external gas of the housing 210, so that the first electrode plate 220 can process the specific substance in the gas, and another portion of the spherical surface can release the substance generated by the electrochemical reaction without interfering with each other.
In some further embodiments, the second electrode plate 240 is opposite to the first electrode plate 220 and is disposed in a central cutaway plane of the case 210. The central cutting plane of the casing 210 is a section with the largest internal area of the casing 210, which can provide a wider arrangement space for the second electrode plate 240, and increase the plate surface area of the second electrode plate 240.
For example, the plate surface of the second electrode plate 240 may be circular, and the diameter of the second electrode plate is the same as the diameter of the sphere of the housing 210, so as to be disposed at the central section of the housing 210, which can make the second electrode plate 240 obtain the largest plate surface area in the spherical housing 210, thereby comprehensively increasing the electrochemical reaction rates of the two electrode plates.
In some alternative embodiments, the ventilation area 212a is an opening or an array of through holes. For example, when the gas permeable region 212a is an opening, the circumferentially inner side of the opening provides a "window" through which gas passes. When the gas permeable areas 212a are through holes, the circumferentially inner side of each through hole provides a "window" through which gas passes.
In some alternative embodiments, the first electrode plate 220 is disposed inside the air permeation region 212a and covers the air permeation region 212a. Here, the "inside of the gas permeable area 212 a" refers to a side of the gas permeable area 212a facing the electrolytic chamber 214. That is, the first electrode plate 220 does not protrude from the case 210, which can protect the first electrode plate 220 from being damaged by the collision.
For example, the first electrode plate 220 may be mounted to the air permeable region 212a of the housing 210 by any connection means, such as clamping, screwing, bonding, and the like.
Of course, the first electrode plate 220 may also cover the outside of the air permeable region 212a, which may reduce the assembly difficulty to some extent. Or when the gas permeable region 212a is an opening, the first electrode plate 220 may be disposed circumferentially inside the opening.
In some alternative embodiments, the first electrode plate 220 has a water-proof gas-permeable membrane. Or the breathable region 212a is provided with a waterproof breathable film, and the first electrode plate 220 is disposed on the inner side or the outer side of the waterproof breathable film. The waterproof breathable membrane may allow gas to pass through while preventing water from passing through.
By providing the waterproof gas-permeable membrane, the electrolyte in the electrolytic chamber 214 can be prevented from leaking, and the gas to be treated is not affected to participate in the electrochemical reaction at the first electrode plate 220.
For example, the second electrode plate 240 may be a nickel plate, but is not limited thereto; the first electrode plate 220 may have a multi-layer film structure, and may include, from the outside to the inside, a catalytic layer, a first waterproof and breathable layer, a current collecting layer, and a second waterproof and breathable layer. Here, directional terms such as "outer" and "inner" are used with respect to an actual usage state of the first electrode plate 220, and with respect to other structures of the first electrode plate 220, the catalytic layer is located at an outermost side of the first electrode plate 220 so as to be in contact with the gas.
The catalytic layer may be a metal catalyst, wherein the metal may be a noble metal or a rare metal, and may be selected from the group consisting of platinum, gold, silver, manganese, and rubidium, for example. The metal catalyst particles may be attached to the carbon black particles. The first waterproof breathable layer and the second waterproof breathable layer can be waterproof breathable films respectively. The current collecting layer can be made into a corrosion-resistant metal current collecting net, such as metal nickel, metal titanium and the like, so that the current collecting layer not only has better conductivity, corrosion resistance and supporting strength. And because first electrode plate 220 itself has certain intensity, can satisfy the sealing strength demand of electrolysis chamber 214 completely, first electrode plate 220 adopts two-layer waterproof ventilative layer also can prevent effectively because the leakage that electrolyte corrodes and arouse in addition.
The electrolytic cavity 214 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 first electrode plate 220 is a cathode for connecting to a negative electrode of a power supply to consume oxygen by performing an electrochemical reaction under the action of an electrolytic voltage. For example, oxygen in the air may undergo a reduction reaction at the first electrode plate 220, that is: o is 2 +2H 2 O+4e - →4OH - 。
The second electrode plate 240 is an anode for connecting with a positive electrode of a power supply to supply a reactant to the first electrode plate 220 by performing an electrochemical reaction under the action of an electrolytic voltage. First electrode plateOH produced by 220 - An oxidation reaction may occur at the second electrode plate 240 and oxygen may be generated, that is: 4OH - →O 2 +2H 2 O+4e - 。
By adopting the structure, the gas processing device 200 can process the oxygen in the storage space of the refrigerator 10 so as to conform to the development concept of low-oxygen preservation, prolong the storage life of food materials such as fruits and vegetables and improve the preservation performance of the refrigerator 10.
Meanwhile, since the second electrode plate 240 generates oxygen during the electrochemical reaction, the oxygen can be utilized and, for example, can be delivered to the high oxygen space 140 of the refrigerator 10, which can improve the air conditioning capability of the refrigerator 10, so that it can create a low oxygen fresh-keeping atmosphere and a high oxygen fresh-keeping atmosphere at the same time.
In order to smoothly discharge the oxygen generated by the second electrode plate 240, the electrolytic chamber 214 may be opened with an exhaust port. Oxygen generated from the second electrode plate 240 may be discharged through the gas outlet.
The power source for the gas treatment device 200 may be a battery, or may be other power supply configurations. For example, when the gas treatment device 200 is disposed within the refrigerator 10, the refrigerator 10 may provide power to the gas treatment device 200 using a main control board, or may provide power to the gas treatment device 200 using a power supply structure of other components inside the refrigerator 10.
In some alternative embodiments, the gas treatment device 200 can also include a gas flow chamber 260, the gas flow chamber 260 having a treatment air duct 266. The airflow chamber 260 is disposed outside the air permeable region 212a and is formed with a fitting opening into which the hemisphere of the case 210 is fitted. For example, the airflow chamber 260 may be substantially in the shape of a hollow cubic column, and the length of the bottom side of the airflow chamber may be the same as the diameter of the spherical housing 210 or may be larger than the diameter of the spherical housing 210, so that the hemisphere of the spherical housing 210 can extend into the inner space of the airflow chamber 260 (e.g., the processing air duct 266) through the mounting opening and achieve a snap fit.
Note that the hemisphere of the spherical housing 210 extending into the airflow chamber 260 has the above-described air permeable region 212a. The wall of the processing air duct 266 may be provided with an inlet 262 and an outlet 264, for example, the inlet 262 of the processing air duct 266 may be communicated with an air outlet of the storage space, and the outlet 264 of the processing air duct 266 may be communicated with an air return opening of the storage space, so that an air circulation channel may be formed, and the air conditioning efficiency of the storage space may be improved.
Of course, the polarities of the first and second electrode plates 220 and 240 may be reversed. For example, in some embodiments, the first electrode plate 220 is an anode for connecting to a positive electrode of a power supply to provide a reactant to the first electrode plate 220 by performing an electrochemical reaction under the action of an electrolysis voltage and generate oxygen. The second electrode plate 240 is a cathode for connecting with a negative electrode of a power supply to consume oxygen by performing an electrochemical reaction under the action of an electrolytic voltage. Oxygen in the air may undergo a reduction reaction at the second electrode plate 240, that is: o is 2 +2H 2 O+4e - →4OH - . OH generated from the second electrode plate 240 - An oxidation reaction may occur at the first electrode plate 220 and oxygen may be generated, that is: 4OH - →O 2 +2H 2 O+4e - 。
In this embodiment, in order to contact the second electrode plate 240 with oxygen in the air, the casing 210 further defines a ventilation chamber 216 located at one side of the electrolytic chamber 214 and communicating with the space outside the casing 210. That is, the gas in the space outside the housing 210 may enter the ventilation chamber 216. For example, the ventilation chamber 216 may be opened with ventilation holes to allow air from the space outside the housing 210 to pass through. The second electrode plate 240 is located between the venting chamber 216 and the electrolytic chamber 214, and spaces the venting chamber 216 and the electrolytic chamber 214. In this way, the side of the second electrode plate 240 facing the ventilation cavity 216 can contact oxygen in the air, and perform an electrochemical reaction using the oxygen as a reactant. Oxygen generated by the electrochemical reaction of the first electrode plate 220 may be discharged from the gas permeable region 212a.
When the first electrode plate 220 is an anode and the second electrode plate 240 is a cathode, the second electrode plate 240 may have a waterproof gas-permeable membrane. Or a waterproof breathable film for separating the ventilation cavity 216 and the electrolysis cavity 214 is arranged in the shell 210, and the second electrode plate 240 is arranged on the side of the waterproof breathable film facing the electrolysis cavity 214. By doing so, leakage of electrolyte to the ventilation chamber 216 through the second electrode plate 240 can be reduced or avoided.

In alternative embodiments, the housing 210 may be transformed into other shapes. For example, the housing 210 may be a hollow cylinder with walls defining an arcuate surface 212. The cylindrical housing 210 is easy to mount and fix, which is beneficial to reducing the mounting difficulty of the gas treatment device 200.
In some further embodiments, the air permeable region 212a is disposed on a half side of the housing 210. The half side of the case 210 means a half of the side of the cylindrical case 210 taken along a central longitudinal section of the cylindrical case 210. The first electrode plate 220 is disposed at the gas permeation region 212a, and the second electrode plate 240 is disposed in a central longitudinal sectional plane of the cylindrical case 210. For example, the plate surface of the second electrode plate 240 may have a rectangular parallelepiped shape having a width equal to the diameter of the cylindrical case 210 and a length equal to the height of the cylindrical case 210 so as to be disposed exactly at the central longitudinal section of the case 210, thereby obtaining the maximum plate surface area.
When the first electrode plate 220 is an anode and the second electrode plate 240 is a cathode, the casing 210 further defines a gas exchange chamber 216 inside the casing 210, the gas exchange chamber being located at one side of the electrolytic chamber 214 and communicating with the space outside the casing 210, as in the above embodiment. That is, the gas in the space outside the housing 210 may enter the ventilation chamber 216. For example, the ventilation chamber 216 may be opened with ventilation holes to allow air in the space outside the housing 210 to pass through. The second electrode plate 240 is located between the venting chamber 216 and the electrolytic chamber 214, and spaces the venting chamber 216 and the electrolytic chamber 214. In this way, the side of the second electrode plate 240 facing the ventilation cavity 216 can contact oxygen in the air, and perform an electrochemical reaction using the oxygen as a reactant. Oxygen generated by the electrochemical reaction of the first electrode plate 220 may be discharged from the gas permeable region 212a. And the ventilation chamber 216 may have a substantially tubular structure, which may enlarge the air intake area of the first electrode plate 220, and may improve the simplicity of the sealing of the device.

The cathode of the gas treatment device 200 may be in gas flow communication with the hypoxic space 120 and reduce the oxygen content of the hypoxic space 120 via an electrochemical reaction. The anode of gas treatment device 200 may be in gas flow communication with high oxygen space 140 and increase the oxygen content of high oxygen space 140 by an electrochemical reaction.
For example, by providing an air inlet line 312 and an air return line 314 between the cathode and the low oxygen space 120, air flow communication between the cathode and the low oxygen space 120 may be achieved; gas flow communication between the anode and the high oxygen space 140 can be achieved by providing an oxygen delivery passage between the electrolysis chamber 214 in which the anode is located and the high oxygen space 140. A gas flow actuating means 320 may be connected to the gas inlet line 312 for causing a gas flow to be formed from the low oxygen space 120 through the gas inlet line 312 to the cathode and back to the low oxygen space 120 after flowing through the return gas line 314.
An oxygen delivery passage is also provided in communication between electrolysis chamber 214 and high oxygen volume 140 for delivering anode-generated oxygen to high oxygen volume 140. For example, the oxygen delivery channel may have a first end 420 connected to the exhaust port and a second end 440 connected to the hyperoxia space 140.
As shown in fig. 4, the gas treatment device 200 is disposed within the press compartment 160 of the refrigerator 10. The press machine compartment 160 has a certain reserved space, and the space utilization of the refrigerator 10 can be improved by installing the gas treatment device 200 using the reserved space. By virtue of the temperature environment of the press cabin 160, the gas processing apparatus 200 can exert high oxygen removal efficiency and oxygen generation efficiency.
Of course, the gas processing device 200 may be selectively disposed at any suitable position in the box 100, and fig. 4 is only illustrated by way of example in the case of being disposed in the pressing chamber 160, but should not be construed as limiting the installation position of the gas processing device 200.
