[0001] The utility model relates to the technical field of heat exchangers, in particular to an anti-corrosion electrophoresis heat exchanger. Background Art

[0002] A heat exchanger is a heat exchange device that can transfer part of the heat of a hot fluid to a cold fluid. Therefore, heat exchangers are often used in chemical, oil refining, food and other fields to utilize their heat exchange principle to achieve waste heat recovery.

[0003] When the heat exchanger is working, a high-temperature fluid needs to circulate inside the heat exchanger all the time. The high-temperature fluid is generally corrosive and tends to erode the internal pipes of the heat exchanger as the heat exchanger is used, which can easily affect the use effect and service life of the heat exchanger. At the same time, impurities will be entrained in the high-temperature fluid. As the impurities move in the heat exchanger, they can easily clog the circulation holes of the heat exchanger, causing the heat exchange efficiency of the heat exchanger to gradually decrease. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0029] like Figures 1 to 7 As shown, the corrosion-resistant electrophoretic heat exchanger includes a shell 1 and a circulation pipe 4 arranged on the shell 1. The circulation pipe 4 is circulated and coiled around the shell 1 from bottom to top, and the tube body 41 of the circulation pipe 4 is passed through the shell 1.

[0030] The shell 1 is provided with multiple layers of partitions 13 distributed up and down, and the tube body 41 of the circulation pipe 4 is pressed and fixed on the partition 13. The partition 13 and the tube body 41 cooperate with the upper and lower multi-layer partitioning inside of the shell 1. The surface of the partition 1 is provided with an electrophoretic anti-corrosion coating. The anti-corrosion coating is sprayed on the surface of the partition 1 by electrophoresis to improve the corrosion resistance of this embodiment, thereby improving the use stability and service life of this embodiment.

[0031] A liquid inlet pipe 2 is provided at the upper end of the shell 1, and the liquid inlet pipe 2 is used to transport high-temperature fluid into the shell 1. A liquid outlet pipe 3 is provided at the lower end of the shell 1, and the liquid outlet pipe 3 is used to discharge the high-temperature fluid out of the shell 1. A through hole 131 is provided on each layer of the partition 13, and the through holes 131 on adjacent partitions 13 are staggered in an up-down manner. The partitions 13 and the through holes 131 cooperate to form a flow channel 14 for fluid circulation. The high-temperature fluid flows through the tube body 41 from top to bottom along the flow channel 14, and then the heat is transferred to the lower-temperature fluid flowing in the tube body 41 through the high-temperature fluid to achieve heat recycling.

[0032] The lower end of the circulation pipe 4 is provided with an inlet end 412, and the fluid with a lower temperature flows into the circulation pipe 4 from the lower inlet end 412. The upper end of the circulation pipe 4 is provided with an outlet end 411, and the fluid flowing in the circulation pipe 4 flows out from the outlet end 411.

[0033] The outlet end 411 is arranged close to the liquid inlet pipe 2, and the inlet end 412 is arranged close to the liquid outlet pipe 3. The temperature of the fluid when flowing out of the liquid outlet pipe 3 is lower than the temperature of the fluid when flowing into the liquid inlet pipe 2 (because part of its heat is conducted to the fluid with lower temperature, that is, the fluid flowing in the circulation pipe 4), and then the fluid at the liquid outlet pipe 3 is preheated to the fluid in the circulation pipe 4, and as the fluid in the circulation pipe 4 is transported, it gradually flows to the vicinity of the liquid inlet pipe 2 with higher temperature. When the fluid in the circulation pipe 4 is discharged outward through the outlet end 411, its temperature is closer to the temperature at the liquid inlet pipe 2, that is, the fluid in the circulation pipe 4 absorbs more heat and can recycle and utilize heat more efficiently.

[0034] The shell 1 includes a front plate 11 and a rear plate 12 that are sealed and installed front and back. The front and rear ends of the shell 1 are sealed by cooperating with the front plate 11 and the rear plate 12. A flange tube 42 is installed at one end of the tube body 41. The tube body 41 can be detachably installed on the front plate 11 through the flange tube 42. Specifically, the flange tube 42 can be bolted to the front plate 11 by bolts, and then one end of the tube body 41 can be detachably installed on the shell 1 to achieve fixation of one end of the tube body 41.

[0035] The other end of the tube body 41 is plugged into a second connecting pipe 46 fixedly mounted on the housing 1 . The second connecting pipe 46 is fixedly mounted on the rear plate 12 and can be fixed by welding or other methods.

[0036] The tube body 41 is provided with a plug-in portion 43 at one end of the connecting tube 46, and the connecting tube 46 is provided with a flared section 461 adapted to the plug-in portion 43. When one end of the tube body 41 is fixed by the flange tube 42, the plug-in portion 43 is plugged and fixed to the flared section 461 to achieve the fixation of the other end of the tube body 41.

[0037] At this time, the tube body 41 is pressed downward and fixed on the partition 13 . At the same time, in order to improve the sealing between the tube body 41 and the partition 13 , a sealing gasket is provided between the tube body 41 and the partition 13 .

[0038] Furthermore, an annular groove 431 is provided on the plug-in portion 43, and an abutment ring 44 is provided on the annular groove 431. The flange tube 42 is tightened and fixed on the front plate 11, and the abutment ring 44 abuts against the inner periphery of the flared section 461 to ensure the sealing of the plug-in assembly between the tube body 41 and the connecting tube 2 46.

[0039] The connecting pipe 2 46 is used to connect one end of the two pipe bodies 41, and the connecting pipe 1 45 is installed on the flange pipe 42. The connecting pipe 1 45 is used to connect the other ends of the two pipe bodies 41. The multiple pipe bodies 41 are connected by matching the connecting pipe 1 45 with the connecting pipe 2 46, and then assembled into a circulation pipe 4.

[0040] As this embodiment is used, the high-temperature fluid flowing in the shell 1 often carries some impurities. As the embodiment is used, the impurities may clog the through holes 131 of the partition 13, thereby causing the heat exchange performance of this embodiment to gradually decrease.

[0041] The tube body 41 is removed from the front plate 11 of the shell 1 through the flange tube 42 so that the interior of the shell 1 can be flushed more conveniently and efficiently to avoid the impact of more pipes in the shell 1 on the flushing effect, that is, to improve the cleaning ability of the interior of the shell 1 to avoid impurities carried by the high-temperature fluid from remaining in the shell 1, thereby reducing the corrosion of this embodiment by the impurities, thereby increasing the service life of this embodiment.

[0042] Furthermore, by removing the tube body 41 and then flushing the through hole 131 on the partition 13, impurities on the through hole 131 can be effectively flushed away to avoid the problem of clogging of the through hole 131, thereby ensuring that this embodiment has good heat exchange efficiency.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
