Product Description Product DescriptionThe vertical tubular furnace is a type of industrial equipment designed with a "vertical tubular structure" as its core. It is widely applied in processes such as heat transfer, reactions, and separations. Leveraging its compact layout, high efficiency, and stable operation, it has become a key piece of equipment in the chemical, energy, and pharmaceutical industries. The core components include vertically arranged metal or specialty material tubes, upper and lower tube sheets, a shell, and associated inlet and outlet piping, along with temperature control components. Different media can be introduced into the tubes and the spaces between them, enabling heat exchange or material reactions through the tube walls to meet specific process requirements in industrial production.Compact Layout: Utilizing a vertical installation method, it significantly saves floor space compared to horizontal equipment, making it particularly suitable for production scenarios with limited workshop space. It allows for vertical process integration with upstream and downstream equipment, optimizing the overall production line layout. Its main advantages are as follows:Efficient Mass and Heat Transfer: The vertical tube design ensures a stable flow state of the media within the tubes or between them, reducing local eddies or stagnant zones and enhancing media contact efficiency. Some products further enhance heat transfer efficiency by incorporating built-in flow guides or fins, achieving a 15%-30% increase in thermal efficiency compared to traditional equipment.Stable Operation and Easy Maintenance: The vertical arrangement of the tubes facilitates the natural settling of impurities in the media, reducing the risk of pipeline blockage. The upper and lower tube sheets are connected using flanges or welds with excellent sealing performance, minimizing leakage risks. A maintenance port is reserved at the top of the equipment, allowing for convenient tube cleaning, replacement, or internal component maintenance without the need for extensive disassembly.Product FeaturesStrong Material Adaptability: Depending on the application scenario, the tubes can be made of materials such as carbon steel, stainless steel, titanium alloy, Hastelloy, or fiberglass-reinforced plastic, to withstand corrosion, high temperatures, or high-pressure environments from different media. For example, stainless steel is commonly used in the chemical industry to handle acidic and alkaline media, while high-temperature alloys are employed in the energy sector for processes exceeding 300°C.Broad Process Compatibility: It can flexibly adapt to various process requirements, serving as a heat exchanger (e.g., steam heating, cold water cooling), a reactor (e.g., tubular reactor for gas-liquid or liquid-liquid reactions), or a separation component within a distillation column. By adjusting the number of tubes, their length, and media flow rates, it meets different capacity and process precision requirements.Intelligent Control: Mainstream products are equipped with temperature, pressure, and flow sensors that can be linked to a central control system for real-time monitoring of equipment operation parameters. Some high-end models support automatic adjustment of media inlet and outlet valve openings to precisely control process temperatures or reaction progress, reducing manual intervention and enhancing production stability.Product ApplicationsChemical Industry: Used for heating acid-base solutions, condensing heat exchange during solvent recovery, or serving as a tubular reactor for chemical reactions such as esterification and polymerization. For example, in coating production, a vertical tubular heat exchanger heats raw materials to reaction temperatures while controlling heat release during the reaction.Energy Sector: In waste heat recovery systems, vertical tubular heat exchangers recover waste heat from boiler flue gases or industrial wastewater to heat cold water or air, enabling energy recycling. They can also serve as core components in biomass energy conversion equipment, facilitating biomass pyrolysis or gasification processes.Pharmaceutical and Food Industries: Vertical tubular equipment made of food-grade stainless steel can be used for processes such as liquid sterilization, juice concentration, and dairy product pasteurization. The smooth, dead-angle-free tubes comply with sanitary standards, preventing media residue contamination and ensuring product safety.
