Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrode structure design, in particular to a new electrode structure for high temperature and high pressure environment. BACKGROUND

[0002] In high temperature and high pressure thermal equipment, the performance and stability of the electrode directly affect the operating efficiency and safety of the equipment. Such equipment is widely used in the fields of energy, aerospace and industrial manufacturing. For example, in high temperature and high pressure reactors, plasma generators and gas turbines, the electrode needs to withstand extreme temperature (above 500℃) and pressure (above 10MPa) conditions, while also ensuring mechanical stability. However, the existing electrode design method usually only focuses on a single aspect, and fails to comprehensively consider the needs of the electrode in terms of heat insulation, cooling and sealing. Therefore, the stability and reliability of the electrode under extreme environment are difficult to fully guarantee.

[0003] The commonly used electrode structure design scheme in the prior art mainly includes high temperature heat insulation design, external cooling design and high temperature sealing design. High temperature heat insulation design usually uses high thermal conductivity ceramic or fiber material to cover the electrode, which can effectively isolate heat and protect the internal structure. However, in high temperature environment, there will be a large thermal stress, which is easy to cause material cracking or electrode deformation, limiting its service life and reliability. External cooling design reduces the electrode temperature through external cooling system such as cooling liquid circulation or cooling air flow. Although this method has obvious cooling effect and can effectively reduce the electrode temperature, the system is complex, which increases the maintenance difficulty and cost of the equipment, and the cooling efficiency is limited, which is difficult to meet the cooling demand in high temperature and high pressure environment. High temperature sealing design usually uses high temperature sealing materials such as metal sealing ring or high temperature rubber sealing ring to ensure the sealing of the electrode and the outside. However, in high pressure environment, high temperature sealing materials are prone to leakage, affecting the normal operation of the electrode and the equipment, and it is difficult to ensure long-term stable work.

However, the present application can be practiced in a variety of ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific implementations disclosed below.

[0022] The utility model provides a kind of novel electrode structure for high temperature high pressure environment, including electrode main body 1 and cooling device 3.Electrode main body 1 inside is equipped with inner flow passage 2, and cooling device 3 is arranged in inner flow passage 2.This design is by setting up inner flow passage 3 in electrode main body 1, and cooling device 3 is installed in inner flow passage, effectively solve the cooling problem of electrode in high temperature high pressure environment, to improve the stability and reliability of electrode.Electrode main body 1 provides mechanical support and conductive function, and cooling device 3 is cooled to electrode main body 1 by inner flow passage 2, and they cooperate with each other, ensure the normal work of electrode under extreme environment.

[0023] In some specific embodiments, the electrode body is a cylindrical hollow structure.The electrode main body 1 is a cylindrical hollow structure.The cylindrical hollow structure can provide better mechanical strength and stability in high temperature high pressure environment.Through this structure design, the electrode main body 1 can better withstand the stress from high temperature high pressure environment, thereby improving the overall stability and service life of the electrode.

[0024] The electrode main body 1 of the cylindrical hollow structure can be realized in various ways.For example, a cylindrical hollow electrode body can be made of high-strength metal materials such as stainless steel or alloy steel or copper.Such materials have good mechanical strength and high-temperature resistance, and can remain stable in high temperature high pressure environment.In addition, reinforcing ribs can be provided inside the electrode body to further enhance its structural strength and stability.As a preferred embodiment, the hollow inner wall of the electrode body (the inner wall of the inner flow pipe 2) can be filled with a high-temperature-resistant insulating material to improve the heat resistance and insulation performance of the electrode.

[0025] In some specific embodiments, the electrode structure includes an electrode main body 1 and a cooling device 3, and further includes a clamping sleeve 4, and the cooling device 3 is connected to the electrode main body 1 through the clamping sleeve 4.The design of the clamping sleeve 4 can ensure the stable connection of the cooling device 3 and the electrode main body 1, thereby providing effective cooling effect in high temperature high pressure environment.The clamping sleeve 4 is connected to the electrode main body 1, ensuring the stability and reliability of the cooling device 3 under high temperature high pressure conditions.

[0026] In some embodiments, the clamping sleeve 4 can be connected to the electrode body 1 in a threaded engagement manner to ensure the stability and sealing of the connection. The cooling device 3 can be a cooling water pipe, which is connected to the inner flow channel 2 of the electrode body 1 through the clamping sleeve 4 to achieve effective injection and circulation of cooling water. Specifically, the threaded engagement connection between the clamping sleeve 4 and the electrode body 1 can be achieved through standard thread machining technology. The accuracy and strength of the threaded engagement can be ensured by selecting appropriate thread specifications and materials. For example, high-strength metal materials can be used for thread machining to ensure reliability in high-temperature and high-pressure environments. Further, sealing rings or sealant can be added at the threaded connection to enhance the sealing performance of the connection and prevent cooling liquid leakage. As a preferred embodiment, a double-thread structure can be designed to provide higher connection strength and stability.

[0027] In some embodiments, the electrode body 1 has a water outlet on the outer wall of the end near the clamping sleeve 4, which penetrates the inner flow channel 2 and the outside world. By providing a water outlet on the outer wall of the end of the electrode body 1 near the clamping sleeve 4, cooling water can flow out of the inner flow channel 2, thereby solving the problem of cooling water discharge in the electrode body 1 in a high-temperature and high-pressure environment. This design ensures that the cooling water can be discharged smoothly, avoiding the retention of cooling water in the inner flow channel, thereby improving the cooling effect and stability of the electrode in a high-temperature and high-pressure environment. The outer wall of the end of the electrode body 1 near the clamping sleeve 4 has a water outlet that penetrates the inner flow channel 2 and the outside world, which can be achieved through precision machining technology. Specifically, the size and position of the water outlet need to be designed according to the specific structure of the electrode body and the cooling water flow to ensure that the cooling water can be effectively discharged. As a preferred embodiment, the water outlet can be designed as multiple small holes to disperse the discharge pressure of the cooling water, further improving the cooling effect.

[0028] In some embodiments, the base of the electrode body 1 is also provided with a sealing ring 5. The sealing ring 5 serves to ensure the sealing performance of the electrode in a high-temperature and high-pressure environment. By providing a sealing ring 5 on the electrode base, leakage problems in a high-temperature and high-pressure environment can be effectively prevented, thereby improving the stability and reliability of the electrode and ensuring long-term stable operation of the electrode in extreme environments. The sealing ring can be made of high-temperature rubber material or metal material to ensure its stability and durability in a high-temperature and high-pressure environment. The shape of the sealing ring can be an O-ring, a U-ring or other suitable structure to adapt to different sealing requirements. In addition, the sealing ring can be installed in an embedded manner or fixed by a fixing device to ensure that it does not easily fall off or shift during use.

[0029] The application can effectively reduce the temperature of the electrode by arranging the inner flow channel 2 in the electrode body 1 and arranging the cooling device 3 in the inner flow channel 2, thereby improving the stability of the electrode in a high-temperature and high-pressure environment. The electrode body 1 adopts a cylindrical hollow structure and connects the cooling device 3 through the clamping sleeve head 4 and the threaded engagement mode, ensuring the reliability and sealing performance of the connection. The cooling water pipe injects cooling water into the inner flow channel 2 and discharges it through the water outlet, further enhancing the cooling effect. The electrode body 1 is made of copper material to improve the heat conduction performance, and the base is provided with a sealing ring to enhance the sealing effect. Through the mutual cooperation of these technical features, the stability and reliability of the electrode in a high-temperature and high-pressure environment are solved. The cylindrical hollow structure design of the electrode body 1 can also effectively increase the flow area of the cooling water and improve the cooling efficiency. The clamping sleeve head 4 is connected with the electrode body 1 through the threaded engagement mode, which ensures the close connection between the cooling device 3 and the electrode body 1 and prevents the leakage of cooling water. The water outlet design penetrating the inner flow channel 2 and the outside ensures the smooth discharge of the cooling water, avoids the retention of the cooling water in the inner flow channel 2, and further improves the cooling effect. The sealing ring 5 on the base further enhances the sealing performance of the electrode and prevents the leakage of cooling water to the outside environment.
