Product DetailsThe heat exchange element material of the device developed is a new type of silicon carbide engineering ceramics, which has excellent performance in high temperature resistance and thermal shock resistance. It is air-cooled from 1000 ℃ to room temperature, and no cracks appear after more than 50 cycles; thermal conductivity It is equivalent to stainless steel; it has good corrosion resistance in oxidizing and acidic media. In the structure, the thermal compensation is successfully solved and the gas sealing problem is solved better. The device has high heat transfer efficiency and significant energy saving effect. It can be used to preheat the combustion air or heat the process gas in certain processes, which can save primary energy, and the fuel saving rate can reach more than 30%. It can strengthen the process and significantly increase the production capacity. . Tubular silicon carbide insert high temperature heat exchanger is a new type of heat exchange device developed to replace metal heat exchangers and solve the defects of unreasonable long-term operation in high-temperature flue gas and the need for cold air to reduce the use effect. The heat exchanger made of this material is a replacement product of high-temperature flue gas waste heat recovery in the world. The tubular silicon carbide insert high-temperature heat exchanger has a compact structure and a large heat exchange area per unit volume. It is compressed by an internal spring to absorb thermal expansion. When the flue gas temperature is 1300°C, the air preheating temperature can reach 600°C or more. The interface part of the heat exchanger adopts corresponding technology to reduce vibration and strengthen sealing to reduce air leakage. The air leakage rate is less than 5% of professional requirements. The silicon carbide heat exchanger is composed of a number of air passages with a square cross-section and a rectangular flue gas passage cross-section of silicon carbide tubes glued together in a crisscross pattern. The air passage and the flue gas passage are double-layered, and the structure is firm and high. With high mechanical strength, it solves the phenomenon of cracking and easy air leakage of the corrugated ceramic heat exchanger separator. Four L-shaped seals are glued at the junction of the air and flue gas channels. The shell is made of steel plate, and the middle is filled with aluminum silicate refractory fiber, which plays a role of sealing, heat insulation and anti-mechanical vibration. The air inlet and outlet discs are internally connected, and the cold and hot air generates a steady flow in the connecting pipe, and the flow rate is stable. The heat exchanger can be widely used in the recovery of flue gas in various industrial furnaces and is an ideal energy-saving devic

Extreme corrosion resistance: meet extreme requirements for corrosion resistance, such as a mixture containing multiple corrosive components
High equipment availability: Robust tube sheet (such as thick metal core) and uniform and constant tube sealing of each tube to ensure the highest reliability against leakage Compact: For example, compared with glass equipment, the heat exchange area can be reduced by up to 70% through efficient direct sintering of silicon carbide tubes
Low maintenance costs: the head is easy to disassemble for direct cleaning or inspection of the pipe Clean: no risk of contamination or reaction of the process medium Performance introduction of perfluoroether sealing ring:
1. High temperature and high pressure resistance: It can work for a long time at a high temperature of 200°C, and can maintain effective elastic recovery, low compression deformation, and maintain excellent sealing performance under high temperature and high pressure.
2. Chemical resistance:
It can withstand more than 1800 kinds of chemicals, solvents and plasma corrosion. It has very high resistance to volume expansion, ensuring long-term sealing under severe working conditions. Why choose pressureless sintered tube? At present, the silicon carbide heat exchange tube researched and developed in the world mainly includes two material systems: reaction sintering SIC and pressureless sintering SiC. Among them, the silicon carbide ceramic material prepared by the reaction sintering process often contains 10-30 % Free silicon, so its corrosion resistance to alkali and strong acid media is poor. In contrast, pressureless sintered silicon carbide ceramic materials are prepared by high-temperature sintering of submicron SiC and non-oxide sintering aids. This material often has excellent comprehensive properties. Therefore, the silicon carbide tube used by our company is Pressureless sintered SiC.
1. Super corrosion resistance, suitable for various strong corrosion conditions.2. The surface is smooth and not easy to scale.3. The heat exchange tube has high hardness and is extremely resistant to wear.4. High temperature resistance 250℃, pressure resistance 1.0MPa.5. Choose high-purity pressureless sintered tube to prevent reaction sintered tube.6. Imported perfluoroether sealing ring is selected, which is resistant to high temperature and corrosion.7. The flow surface of the head, etc. is lined with PTFE or enamel.8. Innovative installation method, safe and reliable, and convenient maintenance.
