[0025] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0027] An electrolytic cell consists of a cell body, an anode, and a cathode, with the anode and cathode chambers usually separated by a diaphragm. Based on the electrolyte, they are classified into three types: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface to produce the desired product. Currently, in the upper equipment of the electrolytic cell, the shell-opening cylinder releases air from the high-temperature valve exhaust port once per shell-opening cycle, and this shell-opening is quite frequent. The two exhaust ports of the high-temperature valve are connected together by a polyurethane sleeve and connector before being connected to the silencer. However, under these high-frequency and high-temperature operating conditions, the polyurethane sleeve and connector connecting the two exhaust ports are very prone to damage and detachment, affecting gas transmission between the high-temperature valve and the silencer.
[0028] Therefore, this application provides a high-temperature valve device for an electrolytic cell, which enables normal gas transmission between the high-temperature valve and the silencer.
[0029] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.
[0030] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a high-temperature valve device for an electrolytic cell provided in an embodiment of this application. A high-temperature valve device 10 for an electrolytic cell includes a high-temperature valve 1, a silencer 2, and a connecting pipe 3. The high-temperature valve 1 has an exhaust port 11. The silencer 2 is disposed above the high-temperature valve 1. The connecting pipe 3 connects the high-temperature valve 1 and the silencer 2, with one end connected to the exhaust port 11 and the other end connected to the silencer 2. Generally, valves with an operating temperature greater than 450 degrees Celsius are referred to as high-temperature valves.
[0031] Thus, compared with the high-temperature valve with two exhaust holes in the related art, in the embodiment, the exhaust hole 11 is only one, and directly communicates with the muffler 2 through the connecting pipe 3, without the need to connect between the two exhaust holes, so that the connecting pipe and the joint connected between the two exhaust holes can be prevented from being damaged and falling off to some extent, so that the high-temperature valve and the muffler can normally transmit gas.
[0032] The connecting pipe 3 can be a polyurethane tubing (PU tubing). In this regard, the material of the connecting pipe is not specifically limited.
[0033] In order to enable the gas flowing out of the high-temperature valve 1 to quickly flow into the muffler 2 for muffling, in some optional embodiments, the extension direction of the connecting pipe 3 is consistent with the up-down direction. The extension direction of the connecting pipe 3 consistent with the up-down direction can be understood as that the two pipe openings of the connecting pipe 3 are arranged in alignment in the up-down direction, or can be understood as that the two pipe openings of the connecting pipe 3 are not arranged in alignment in the up-down direction.
[0034] It can be understood that if the two pipe openings of the connecting pipe 3 are not arranged in alignment in the up-down direction, the time of the gas in the connecting pipe 3 will be prolonged, so that the gas is difficult to quickly flow into the muffler 2 for muffling. Therefore, in the embodiment, the central axes of the two pipe openings of the connecting pipe 3 coincide. That is, the two pipe openings of the connecting pipe 3 are arranged in alignment in the up-down direction.
[0035] Please refer to Figures 2 to 5 , Figure 2 the cross-sectional view of the connecting pipe in the high-temperature valve device for the electrolytic cell provided in the embodiment of the present application, Figure 3 is Figure 2 the enlarged schematic view of the partial structure at A in FIG. 8, Figure 4 the another cross-sectional view of the connecting pipe in the high-temperature valve device for the electrolytic cell provided in the embodiment of the present application, Figure 5 is Figure 4 the enlarged schematic view of the partial structure at B in FIG. 9. In order to reduce the noise of the gas flowing in the connecting pipe 3, as an optional embodiment, the pipe wall of the connecting pipe 3 is provided with a muffling structure. In this way, the noise generated by the gas flowing in the connecting pipe 3 can be reduced by the arrangement of the muffling structure.
[0036] Specifically, the muffling structure can include a plurality of spaced protrusions 4 arranged on the pipe wall of the connecting pipe 3; the protruding direction of the protrusions 4 is consistent with the radial direction of the connecting pipe 3. In this way, the sound generated by the gas flowing in the connecting pipe 3 will be blocked by the protrusions 4, and the noise of the gas in the flowing process is reduced.
[0037] If the noise generated by the gas near the muffler 2 is smaller, the noise eliminated by the muffler 2 is smaller, and therefore, as an optional embodiment, the distance between the two protrusions 4 gradually decreases in the direction near the muffler 2. That is, the closer to the muffler 2, the stronger the sound blocking effect of the protrusion 4, the smaller the noise generated by the gas entering the muffler 2, and the smaller the noise eliminated by the muffler 2.
[0038] As shown in Figure 3 In order to improve the noise reduction effect of the protrusion 4, in some optional embodiments, the top of the protrusion 4 is provided with a pit 41. In this way, the noise generated by the gas is more consumed in the propagation process, so that the noise generated by the gas entering the muffler 2 is smaller, and the noise eliminated by the muffler 2 is further reduced.
[0039] As shown in Figure 5 In other embodiments, an acoustic channel 42 can be formed in the protrusion 4. Similarly, the setting of the acoustic channel 42 also converts part of the sound energy into kinetic energy of the gas to reduce the noise generated by the gas flowing in the connecting pipe 3.
[0040] Specifically, the acoustic channel 42 penetrates the protrusion 4, and the extension direction of the acoustic channel 42 is consistent with the protruding direction of the protrusion 4. In this way, the acoustic channel 42 is convenient to open.
[0041] It should be noted that in the present embodiment, the protrusion 4 can be integrally formed on the pipe wall of the connecting pipe 3, or the protrusion 4 can be formed externally and then welded with the pipe wall of the connecting pipe 3. Herein, the connection mode of the protrusion 4 and the pipe wall of the connecting pipe 3 is not specifically limited.
[0042] The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary description, and cannot be understood as a limitation of the present patent, and for those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.
[0043] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
