Description

Technical Field

[0001] The utility model belongs to the field of chlorine recovery, and specifically relates to a chlorine detection and recovery device for a liquid flow battery. Background Art

[0002] The electrolyte of the liquid flow battery system is divided into sulfuric acid-based solution, hydrochloric acid-based solution and sulfuric acid-hydrochloric acid-based mixed solution. The electrolyte will produce volatile acidic waste gas during the charging and discharging process. The hydrochloric acid-based electrolyte will even produce toxic gases such as chlorine. The chlorine detection and recovery device is used to recover and detect chlorine.

[0003] When the existing chlorine recovery device recovers chlorine, the chlorine recovery device is connected to the pipeline of the liquid flow battery system, and the storage tank stores the recovered chlorine. When the storage tank needs to be replaced, there is no structure to seal the connecting pipeline, which easily leads to chlorine leakage in the liquid flow battery system.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a chlorine gas detection and recovery device for a liquid flow battery, thereby solving the technical problems in the prior art.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0008] The storage tank is located at the bottom of the recovery shell, and a third connecting pipe threadedly matched with the second connecting pipe is installed on the upper side of the storage tank. A second plugging component transmission-matched with the first plugging component is installed in the third connecting pipe, wherein the inner side of the third connecting pipe is provided with an internal thread, and the outer side of the second connecting pipe is provided with an external thread meshing with the internal thread.

[0009] Optionally, the first plugging assembly includes a fixing ring installed in the second connecting tube, a first plugging head located on the upper side of the fixing ring, a fixing frame installed on the lower side of the fixing ring, and a first tension spring installed between the fixing frame and the first plugging head; a first inclined surface which is in low contact with the fixing ring is provided on the lower side of the first plugging head.

[0010] Optionally, the second plugging assembly includes a fixed plate installed in the third connecting pipe, a second plugging head located in the storage tank and corresponding to the third connecting pipe, and a second tension spring installed between the second plugging head and the fixed plate; a second inclined surface is provided on the lower side of the second plugging head and is in low contact with the pipe mouth of the third connecting pipe; a socket is opened on the lower side of the fixed frame, and an insertion rod corresponding to the socket is installed on the upper side of the fixed plate, and the insertion rod corresponds to the first plugging head.

[0011] A chlorine gas detection device for a liquid flow battery comprises a chlorine gas recovery device for a liquid flow battery as described in any one of the above.

[0012] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0013] By setting up the first plugging component and the second plugging component, when the storage tank and the recovery shell are disassembled, the first plugging component and the second plugging component can respectively block the second connecting pipe and the third connecting pipe, thereby reducing the situation where chlorine gas leakage causes environmental pollution and even endangers personal safety. When the storage tank and the recovery shell are installed, the second plugging component squeezes the first plugging component to cancel the blockage of the second connecting pipe, and the air pump generates gas to squeeze the second plugging component to cancel the blockage of the third connecting pipe, thereby facilitating the recovery of chlorine gas and collecting it in the storage tank for storage.

[0027] By setting up the first plugging component 7 and the second plugging component 11, when the storage tank 4 and the recovery shell 1 are disassembled, the first plugging component 7 and the second plugging component 11 can respectively block the second connecting pipe 3 and the third connecting pipe 5, thereby reducing the situation where the leakage of chlorine gas causes environmental pollution and even endangers personal safety. When the storage tank 4 and the recovery shell 1 are installed, the second plugging component 11 squeezes the first plugging component 7 to cancel the blockage of the second connecting pipe 3, and the gas generated by the air pump 6 squeezes the second plugging component 11 to cancel the blockage of the third connecting pipe 5, thereby facilitating the recovery and collection of chlorine gas into the storage tank 4 for storage.

[0028] like Figure 2-4 As shown, the first plugging assembly 7 of this embodiment includes a fixing ring 701 installed in the second connecting pipe 3, a first plugging head 702 located on the upper side of the fixing ring 701, a fixing frame 703 installed on the lower side of the fixing ring 701, and a first tension spring 704 installed between the fixing frame 703 and the first plugging head 702; the lower side of the first plugging head 702 is provided with a first inclined surface which is in low contact with the fixing ring 701;
