Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline anti-corrosion, in particular to a pipeline anti-electrochemical corrosion device. Background Art
[0002] The EDI module integrates electrodialysis technology and ion exchange technology. Through the selective permeation of anions and cations by anion and cation exchange membranes and the exchange of ions by ion exchange resins, the directional migration of ions is achieved under the action of a DC electric field, thereby completing the deep desalination of water.
[0003] While desalting, the hydrogen ions and hydroxide ions produced by water electrolysis regenerate the ion exchange resin, so ultrapure water can be continuously produced without acid-base chemical regeneration. However, after EDI undergoes ion exchange, some anions and cations will precipitate, and many connecting pipes in pure water systems are made of stainless steel, which is prone to electrochemical corrosion, resulting in corrosion of pipes and precipitation of metal ions, which will not only cause pipe leakage, but also damage the EDI module and affect equipment operation.

[0007] Compared with the prior art, the utility model has the following beneficial effects:
[0008] Since the conductive module is connected to the pipe body, the liquid in the pipe body is in direct contact with the conductive module and has a larger contact area, and the ions in the water can be efficiently conducted out of the pipe through the conductive module, thus avoiding electrochemical corrosion of the metal pipe at the downstream end.
[0009] As a preferred solution, the upstream interface and the downstream interface are both three-way valve structures, and two ends of the three-way valve are respectively connected to the tube body and the conductive module.

[0024] like Figure 1 As shown, the utility model proposes a pipeline anti-electrochemical corrosion device, including: a pipe body 10, an upstream interface 2, a downstream interface 4, a conductive module and a grounding module 9, wherein at least two conductive modules are provided, and here the first conductive module 3 and the second conductive module 5 are taken as examples, the first conductive module 3 and the second conductive module 5 are respectively connected to the two ends of the pipe body 10, and the first conductive module 3 and the second conductive module 5 are respectively electrically connected to the grounding module 9 through the first wire 7 and the second wire 8. Exemplarily, the grounding module 9 is designed as a grounding bar; the upstream interface 2 and the downstream interface 4 are respectively connected to the two ends of the pipe body 10. The device can connect the corresponding components according to different application requirements. For example, by connecting the upstream interface 2 to the outlet channel 1 of the EDI module, anions can be removed from the liquid in the EDI treatment process.
[0025] Using the above solution,
[0026] Since the conductive module is connected to the pipe body 10, the liquid in the pipe body 10 is in direct contact with the conductive module and has a larger contact area, and the ions in the water can be efficiently conducted out of the pipe through the conductive module, thereby avoiding electrochemical corrosion of the downstream metal pipe 6.
[0027] As a preferred solution, both the upstream interface 2 and the downstream interface 4 are designed as a three-way valve structure, the three-way valve has three interconnected outlets, the two ends of the three-way valve are respectively connected to the pipe body 10 and the conductive module, and the other end of the three-way valve is used as a channel connecting the upstream or downstream. In this way, the structure of the upstream interface 2 and the downstream interface 4 is simple and the materials are convenient to obtain, which saves costs.
[0028] As a preferred solution, the pipe body 10, the upstream interface 2 and the downstream interface 4 are all made of non-conductive materials, so that the anions can more efficiently pass through the conductive module and the wire in sequence, and finally be guided from the grounding module 9 to the ground.
