Stainless Steel Heat Exchanger

Gas-oil tube heat exchanger

As a widely used heat exchange equipment in the industrial field, gas oil tube heat exchangers play an important role in various industries such as petroleum, chemical, and energy due to their high efficiency and stable performance. This article will provide a detailed introduction to the basic structure, working principle, performance characteristics, and application status of gas oil tube heat exchangers.

    product detail

    Basic structure:
    Gas oil tube heat exchanger, as the name suggests, is a device used for heat exchange between gas and oil. It is mainly composed of shell, tube bundle, tube plate, head and other parts. The shell is mostly circular, with parallel tube bundles arranged inside, and the two ends of the tube bundles are fixed on the tube plate. Gas and oil flow separately inside and outside the tube, exchanging heat through the wall of the tube bundle.
    . Shell: protects the internal tube bundle and fluid, usually with high pressure bearing capacity.
    . Bundle: Composed of multiple tubes arranged in parallel, it is the main component for heat transfer.
    . Tube plate: used to fix the tube bundle and ensure its stable position inside the shell.
    . Head: located at both ends of the shell, used to enclose the shell and connect inlet and outlet pipelines.

     

    Working principle:
    In a gas oil tube heat exchanger, gas and oil flow through the inside and outside of the tube respectively for heat exchange. Specifically, high-temperature gas flows inside the tube (known as the tube side), while low-temperature oil flows outside the tube (known as the shell side). The gas transfers heat to the wall of the tube bundle, which in turn transfers heat to the oil, thereby achieving heat transfer.
    To improve heat transfer efficiency, a certain number of transverse baffles are usually installed inside the shell. These baffles not only prevent fluid short circuits and increase fluid velocity, but also force the fluid to cross flow through the tube bundle multiple times along the prescribed path, greatly increasing turbulence and enhancing heat transfer efficiency.
    Performance characteristics
    1. Efficient and energy-saving: Gas oil tube heat exchangers have high heat transfer efficiency, which can fully utilize heat and reduce energy consumption.
    2. Wide applicability: Suitable for various media and working conditions, such as steam, water, oil, and weakly corrosive chemical raw materials.
    3. Structural stability: Adopting a sturdy shell structure and stable tube bundle design to ensure stable operation of the equipment under high pressure and high temperature conditions.
    4. Easy to maintain: Some types of tubular heat exchangers, such as U-shaped tubular heat exchangers, allow for free expansion and extraction of heat exchange tube bundles, making them easy to clean and maintain.


    Application:
    Gas oil tube heat exchangers have a wide range of applications in industrial production. In the petroleum industry, it is often used in processes such as oil and gas separation and crude oil heating; In the chemical industry, it is used for heating and cooling various chemical raw materials; In the field of energy, it can be used for heat recovery and waste heat utilization. In addition, with the increasing awareness of environmental protection and continuous technological progress, countries are actively developing environmentally friendly cleaning technologies to reduce energy consumption and minimize environmental impact.
