Technical Field
[0001] This utility model belongs to the field of electrolytic cells, and in particular relates to a medium heat exchange transfer device for multiple electrolytic cells. Background Technology
[0002] Electrolytic cell preheating is a crucial step in electrolysis industrial production, primarily used to heat the electrolytic cell to a suitable temperature range before it is put into operation. This process is significant for ensuring the normal operation of the electrolytic cell, improving electrolysis efficiency, and extending equipment lifespan. It allows the electrolyte to reach its optimal electrolytic state, thereby increasing current efficiency and reducing energy loss; it avoids thermal stress caused by sudden temperature changes when the electrolytic cell is directly energized in a cold state, preventing cracks or damage to the cell lining material; and it ensures a more uniform temperature distribution within the electrolytic cell, reducing localized overheating or undercooling, thus guaranteeing the stability of the electrolysis process.
[0003] Existing heat exchange methods mainly rely on gas burners, electric heaters, or electrodes or heating elements inside the electrolytic cell, increasing energy consumption. Furthermore, in multi-cell operation, the heat exchange medium is directly refluxed for cooling, resulting in heat waste.
[0004] In summary, a multi-electrolysis cell medium heat exchange transfer device is proposed. Utility Model Content

[0031] Referring to the accompanying drawings, this embodiment provides a multi-electrolysis cell medium heat exchange transfer device, comprising:
[0032] The outer casing 1 has an inlet 9 and several outlets 8;
[0033] Isolation groove 3 isolates each pair of adjacent outlets 8 from each other;
[0034] Control plug 4 controls the connection and disconnection between isolation 3 and inlet 9;
[0035] The return tank 2, together with the upper cover 6, forms a closed space for receiving the returned heat exchange medium;
[0036] The return channel 2 is connected to the isolation channel 3 by changing its relative position to the control plug 4.
[0037] Inlet 9 is connected to the heat exchange medium supply system, and outlet 8 is connected to the heat exchanger. The heat exchanger is connected to the electrolytic cell for cooling the electrolytic cell. Under normal cooling conditions, drive mechanism 5 moves control plug 4 along the axis, connecting water inlet space 1-2 to outlet 8 corresponding to drive mechanism 5 through inlet 3-2, thereby supplying heat exchange medium to the heat exchanger. When an additional electrolytic cell needs to be added, the heat exchange medium of the currently operating electrolytic cell flows back to return tank 2. At this time, drive mechanism 5 corresponding to the additional electrolytic cell is activated, causing control plug 4 to move a certain distance. At this time, control plug 4 is not disengaged from isolation tank 3, which means the water inlet... The heat exchange medium in space 1-2 cannot enter the corresponding outlet 8 through the corresponding inlet 3-2. At this time, the radial through hole 4-3 is connected to the radial opening 2-3. The hot heat exchange medium that returns enters the cavity 4-2 through the radial opening 2-3 and the radial through hole 4-3, and flows into the corresponding outlet 8 through the inlet 3-2, realizing the preheating function of the hot medium on the electrolytic cell. When the set temperature is reached, the drive mechanism 5 continues to operate, causing the radial through hole 4-3 to be misaligned with the radial opening 2-3, and opening the inlet 3-2, so that the heat exchange medium in the water inlet space 1-2 flows into the outlet 8 through the inlet 3-2.
[0038] In this embodiment, the outer shell 1 is provided with an inlet space 1-2 and an outlet space 2-1. The inlet space 1-2 is provided with an inlet 9, and the outlet space 2-1 is provided with an outlet 8. The isolation groove 3 separates the inlet space 1-2 and the outlet space 2-1.
[0039] The heat exchange medium is stored in the inlet space 1-2 through the inlet 9, waiting for the inlet 3-2 to be opened.
[0040] In this embodiment, the isolation tank 3 includes a partition 3-1 and an inlet 3-2. The partition 3-1 separates each of the outlets 8, and the inlet 3-2 is provided in multiple ways and is arranged corresponding to the outlets 8.
[0041] The outlet 8 is preferably provided with 6 outlets, and the corresponding partition 3-1 is also provided with 6 outlets, so that each outlet 8 is not connected and the heat exchange medium of other electrolytic cells will not flow in when one electrolytic cell is used, thus avoiding energy waste.
[0042] In this embodiment, the control plug 4 includes a cylinder 4-1, one end of which is connected to the water inlet 3-2, and the other end is slidably connected to the return channel 2. The middle part of the cylinder 4-1 is a cavity 4-2, which connects the return channel 2 and the isolation channel 3.
[0043] The cylinder 4-1 separates the water inlet space 1-2 from the outlet 8, serving as an opening and closing mechanism. During preheating, it connects the return tank 2 to the outlet 8 through the cavity 4-2, allowing the hot heat exchange medium to flow back into the corresponding electrolytic cell heat exchanger.
[0044] In this embodiment, the upper cover 6 is provided with a driving mechanism 5, which is used to drive the cylinder 4-1 to move axially.
[0045] In this embodiment, the driving mechanism 5 includes a screw 5-1, which is threadedly connected to one end of the cylinder 4-1 near the return groove 2.
[0046] The screw 5-1 rotates under the drive of the motor 5-2. The rotation of the screw 5-1 drives the cylinder 4-1 to move along the axis, thereby realizing two actions: one is to open the water inlet 3-2 to connect the water inlet space 1-2 with the outlet 8, and the other is to connect the return channel 2 with the outlet 8 through the cavity 4-2.
[0047] In this embodiment, the reflux groove 2 is provided with a sliding sleeve 2-2, and the inside of the sliding sleeve 2-2 is slidably connected to the cylinder 4-1.
[0048] In this embodiment, the sliding sleeve 2-2 is provided with a radial opening 2-3, and the cylinder 4-1 is provided with a radial through hole 4-3. The driving mechanism 5 drives the cylinder 4-1 to move, so that the radial opening 2-3 connects to the radial through hole 4-3.
[0049] The sliding sleeve 2-2 is provided with a radial opening 2-3. When the screw 5-1 rotates and drives the cylinder 4-1 to move in the direction of the motor 5-2, the radial opening 2-3 and the radial through hole 4-3 will first be connected. At this time, the cylinder 4-1 and the water inlet 3-2 are not separated, and the preheating condition is achieved. When the screw 5-1 continues to move, the radial opening 2-3 and the radial through hole 4-3 will be misaligned and closed. At this time, after the cylinder 4-1 continues to move a certain distance, it will be separated from the water inlet 3-2.
[0050] In this embodiment, a connecting post 3-3 is provided on the side of the isolation groove 3 away from the outlet 8. The connecting post 3-3 fixes the return groove 2 and the upper cover 6 to the outer shell 1. The connecting post 3-3 fixes the outer shell 1, the return groove 2 and the upper cover 6 together.
[0051] In this embodiment, a reflux inlet 10 is provided outside the reflux tank 2. The reflux inlet 10 is connected to the reflux of the electrolytic cell heat exchanger, which can keep the electrolytic cell inactive at the set temperature and quickly put it into operation at any time.
[0052] 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.
