Description

Technical Field

[0002] The cooling water pool of raw anode carbon blocks plays an extremely important role in ensuring production safety, improving production efficiency and protecting the environment.

[0003] The cooling water pool of the raw anode carbon block plays a vital role in the production process. It not only ensures that the carbon block is baked at the predetermined temperature, but also effectively reduces the resistivity of the carbon block during use, thereby improving the electrolysis efficiency. In addition, the cooling water pool can also control the temperature distribution of the carbon block, reduce the deformation and cracking of the carbon block during the electrolysis process, and extend the service life of the carbon block.

[0004] Specifically, the cooling water pool controls the temperature of the carbon blocks to prevent them from deforming or cracking at high temperatures, thereby ensuring the stable use of the carbon blocks in the electrolyzer. At the same time, the cooling process can also reduce the emission of harmful gases, protect the environment and the health of workers. In addition, reasonable cooling can also reduce the resistivity of the carbon blocks, reduce energy consumption during the electrolysis process, and improve production efficiency.

[0025] Refer to Figures 1 to 3The working process of the water pool constant temperature control system according to an embodiment of the present invention is as follows: four thermal resistance thermometers 3 respectively obtain the temperature of the cooling water in the corresponding area of ​​the water pool 1. When the average temperature of the four temperatures obtained is higher than the predetermined temperature (when there is only one thermal resistance thermometer 3, the temperature of the cooling water detected by this thermal resistance thermometer 3 is compared with the predetermined temperature), the PLC distributed I / O cabinet 5 controls the water inlet pipe valve 4 and the catenary water pool outlet valve 6 to open.

At the same time, the original anode water pump room PLC controller 7 controls the water pump 8 to stop running, and controls the front valve 10 and the rear valve 12 to close, thereby stopping the injection of cooling water into the water pool 1, and allowing the existing cooling water in the water pool 1 to flow out through the catenary water pool outlet valve 6, thereby restoring the cooling water level in the water pool 1 to the preset liquid level.

[0028] When the liquid level meter 2 detects that the liquid level of cooling water in the water pool 1 is lower than the preset liquid level, the PLC distributed I / O cabinet 5 controls the water inlet pipe valve 4 to open, and controls the catenary water pool outlet valve 6 to close. At the same time, the original anode water pump room PLC controller 7 controls the water pump 8 to run, and controls the front valve 10 and the rear valve 12 to open, thereby injecting cooling water into the water pool 1 to restore the liquid level of cooling water in the water pool 1 to the preset liquid level.
