Description

Technical Field

[0001] The utility model relates to the technical field of electrolysis of carbon dioxide, and more specifically to an electrolysis of carbon dioxide reactor with a pressure relief function. Background Art

[0002] With the acceleration of the global industrialization process, the consumption of fossil energy has continued to increase, resulting in a large amount of carbon dioxide being emitted into the atmosphere, causing serious environmental problems. The electrolysis of carbon dioxide technology uses electric current to decompose carbon dioxide into usable gas products under specific conditions. By applying a DC power supply, an electrolysis reaction is carried out in a carbon dioxide solution or a pure carbon dioxide medium, causing carbon dioxide molecules to be adsorbed and precipitated on the surface of the conductor, thereby producing different gas products at the anode and cathode. These gas products can be further converted into high-value-added chemicals, such as carbon monoxide, hydrogen, hydrocarbons, etc., providing a new source of raw materials for the energy and chemical industries.

[0003] The shortcomings of the existing technology: During the electrolysis process of the carbon dioxide electrolysis reactor, the resistance and conductivity inside the reactor will change as the electrolysis process proceeds, so the current will also fluctuate. When the current is too large, the energy consumption inside the reactor increases rapidly, which can easily cause the equipment to overheat and further cause safety hazards. In addition, excessive current may also cause equipment damage and reduce the service life of the reactor. A large amount of heat will be generated inside the reactor during the electrolysis process, and the temperature will rise too quickly, which can easily cause a sharp increase in the pressure inside the reactor. Therefore, it is necessary to design a carbon dioxide electrolysis reactor with a pressure relief function. Utility Model Content

The top of the valve body 601 is fixedly connected to the protective cap 605. The protective cap 605 is provided with an adjusting screw 606. The adjusting screw 60 6 is fixedly connected to the top of the piston rod 602, and a fastening nut 607 is threadedly connected to the adjusting screw 606. By rotating the adjusting screw 606 and the fastening nut 607, the positions of the piston rod 602 and the piston plate 603 can be adjusted, thereby controlling the opening and closing of the pressure relief mechanism 6, and realizing precise control of the internal pressure of the reactor.

[0026] The working principle of the utility model is as follows: first, carbon dioxide and electrolyte are added into the cavity 101 of the reactor body 1, and the electrolysis equipment is started to start the electrolysis reaction. During the reaction, the pressure sensor 13 and the temperature sensor 14 will monitor the pressure and temperature changes inside the reactor in real time, and transmit the data to the control system. When the pressure exceeds the set value, the control system will send a signal to the pressure relief mechanism 6 to move the piston rod 602 and the piston plate 603, thereby opening the pressure relief mechanism 6 and discharging the excess pressure. At the same time, when the temperature exceeds the set value, the control system will send a signal to the temperature control mechanism 10 to automatically adjust the working state of the heater 1004 and the cooler 1005 to keep the temperature inside the reactor stable. Through the real-time monitoring of the pressure sensor 13 and the temperature sensor 14 and the intelligent control of the control system, the pressure and temperature inside the reactor can be accurately controlled to ensure the smooth progress and safe operation of the electrolysis reaction.
