Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cells, and in particular relates to a heat exchange medium distribution device for multiple electrolytic cells. Background Technology

[0002] Temperature control is crucial in the operation of electrolytic cells. To maintain stable operation within a suitable temperature range, temperature regulation is achieved through a heat exchange medium. However, in multi-electrolytic cell systems, the heat exchange medium needs to be rationally distributed to ensure uniform and stable heat exchange in each cell. In multi-electrolytic cell systems, if electrolytic cells need to be started sequentially or additional cells need to be added during operation, a preheating device using the absorbed heat exchange medium is proposed to quickly bring the cells into operation and reduce energy waste.

[0038] Referring to the accompanying drawings, this embodiment provides a multi-electrolysis cell heat exchange medium distribution device, comprising:

[0039] Heat exchange plate 1 is connected to the motor slot;

[0040] The heat exchange section 2 has several partitioned spaces inside for heat exchange of different parts of the heat exchange plate 1;

[0041] Distribution section 3 is connected to heat exchange section 2. Distribution section 3 is provided with flow divider 5 inside, which is used to distribute heat exchange medium to different spaces of heat exchange section 2.

[0042] The reflux control unit 4 is located at the edge of the heat exchange unit 2. The heat exchange medium is refluxed or preheated at different positions of the heat exchange plate 1 through the reflux control unit 4.

[0043] The heat exchange medium flows in through the distribution section 3, and then enters the corresponding space of the heat exchange section 2 through the diversion section 5, where heat exchange occurs at the corresponding position. The heat exchange medium is then discharged through the return control section 4 or flows into an adjacent heat exchange space to preheat the space in preparation for use.

[0044] In this embodiment, the heat exchange unit 2 includes a heat exchange space 2-1 and a distribution space 2-3. The heat exchange space 2-1 is provided with multiple spaces, and the heat exchange space 2-1 is provided with an inlet and an outlet. The inlet is connected to the distribution space 2-3. The distribution space 2-3 is provided with a distribution unit 3, and the outlet is connected to the reflux control unit 4.

[0045] The heat exchange section 2 has multiple heat exchange spaces 2-1. The heat exchange medium enters through the inlet and exits through the outlet, then enters the reflux control section 4. The distribution space 2-3 is connected to the inlet of all the heat exchange spaces. Under the control of the flow distribution section 5, the heat exchange medium enters the space that needs heat exchange for heat exchange.

[0046] The heat exchange section 2 also includes drain outlet 3 2-5 and drain outlet 4 2-6. When only a single heat exchange space 2-1 is needed, the space corresponding to drain outlet 3 2-5 is in a state of heat exchange medium being introduced. The heat exchange medium enters the reflux control section 4 through drain outlet 3 2-5 and is directly discharged. If both heat exchange spaces 2-1 need to work simultaneously, that is, the reflux control section 4 rotates to connect drain outlet 3 2-5 and drain outlet 4 2-6, respectively, to the heat exchange spaces 2-1 corresponding to drain outlet 3 2-5. At this time, the heat exchange medium, carrying a portion of the heat from the heat exchange space 2-1 corresponding to drain outlet 3 2-5, enters the space 2-6 to preheat it, so that the electrolytic cell can quickly reach the operating temperature. After the temperature is reached, the heat exchange medium is introduced into the heat exchange space 2-1 corresponding to drain outlet 4 2-6, and the medium is discharged through drain outlet 4 2-6.

[0047] If the space corresponding to drain outlet 1 2-1 needs to be heat exchanged first, and then the space corresponding to drain outlet 3 2-5 needs to be heat exchanged, the medium first enters the corresponding reflux control unit 4 through drain outlet 1 2-1, and then enters the heat exchange space corresponding to drain outlet 3 2-5 through the other heat exchange spaces 2-1 and the reflux control units 4 corresponding to drain outlet 3 2-5 and drain outlet 4 2-6.

[0048] When in operation, drain outlet 2-2 is closed.

[0049] In this embodiment, the distribution unit 3 includes an inlet tank 3-1, a connecting tank 3-2, and a return tank 3-3. One end of the connecting tank 3-2 is connected to the inlet tank, and the other end is connected to the return tank 3-3. The connecting tank 3-2 is connected to the inlet of the heat exchange space 2-1.

[0050] In this embodiment, the connecting groove 3-2 is provided with a distribution groove 3-4, which is connected to the inlet of the heat exchange space 2-1 and the flow divider 5.

[0051] The heat exchange medium enters through the inlet tank 3-1, and after passing through the diversion section 5 in the distribution tank 3-4, it reaches the corresponding heat exchange space 2-1. When multiple heat exchange spaces 2-1 need to work at the same time, the heat exchange medium enters the next distribution tank 3-4 after passing through the connecting tank 3-2.

[0052] After the operation is completed, the heat exchange medium is discharged through the return water tank 3-3.

[0053] In this embodiment, the diversion section 5 includes a diversion block 5-2 rotatably connected to the distribution groove 3-4, and the diversion block 5-2 has a T-shaped channel inside that can communicate with the heat exchange space 2-1.

[0054] The rotation of the diversion motor 5-1 drives the diversion block 5-2 to rotate, thereby connecting the water inlet tank 3-1 with different heat exchange spaces 2-1.

[0055] In this embodiment, the reflux control unit 4 includes a housing 4-1 and a rotating shaft 4-3. The rotating shaft 4-3 is rotatably connected inside the housing 4-1. The housing 4-1 has multiple openings, which are connected to the outlet of the heat exchange space 2-1.

[0056] The outer casing 4-1 is provided with a reflux port 4-2 to connect the heat exchange space 2-1 with the rotating shaft 4-3.

[0057] In this embodiment, the rotating shaft 4-3 is provided with a connecting channel 4-3-1 and a single row channel 4-3-3. The connecting channel 4-3-1 can be connected to multiple heat exchange spaces 2-1, and the single row channel 4-3-3 can be connected to one heat exchange space 2-1.

[0058] In this embodiment, the single-row channel 4-3-3 is arranged along the axis and has a water inlet 4-3-2 connected to the heat exchange space 2-1 in the radial direction.

[0059] In this embodiment, the end of the rotating shaft 4-3 is provided with a drainage cover 2-7, and the drainage cover 2-7 is provided with an isolation part for isolating the connecting channel 4-3-1 and the single-row channel 4-3-3.

[0060] In this embodiment, the isolation part is the isolation pad 2-8.

[0061] When one heat exchange space 2-1 is working, the drain motor 4-4 rotates, connecting the inlet 4-3-2 and the outlet 2-5. The heat exchange medium enters the single-row channel 4-3-3 through the inlet 4-3-2 and is then discharged through the outlet 2-9 on the drain cover.

[0062] When the two heat exchange spaces 2-1 are working, the drain motor 4-4 rotates, connecting the connecting channel 4-3-1 with the drain outlet 2-5 and the drain outlet 2-6. The heat exchange medium is discharged through the connecting channel 4-3-1 and the drain outlet 2-9.

[0063] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
