Application of electric heating in heating of complex equipment

In the field of industrial production, there are often a large number of equipment with complex structures and various functions. These complex equipment face many challenges in their normal operation in low-temperature environments, and electric heating technology plays a key role with its unique advantages.

For some large and complex equipment such as reaction towers and heat exchangers in chemical production, traditional heating methods can hardly meet their heating needs. Electric heating can be flexibly laid according to the irregular shapes of these equipment. For example, in the tower body, tower kettle, top condenser and other parts of the reaction tower, by wrapping the electric heating tape along the surface of the equipment or customizing the laying method, it can ensure that all key parts of the equipment can obtain stable heat. The electric heating system can provide a suitable temperature environment for the chemical reaction in the reaction tower, ensuring the stability of the reaction rate and product quality. For heat exchangers, electric heating can prevent the medium from solidifying or increasing viscosity due to low temperature, thereby maintaining good heat exchange efficiency.

In the process of oil extraction and refining, oil wellhead equipment, oil pipelines, and various oil storage tanks constitute a complex equipment network. Oil wellheads are prone to freezing in cold weather, affecting the normal extraction of crude oil. Electric heating can be directly applied to valves, pipelines and other parts of the wellhead device to prevent crude oil from solidifying at the wellhead due to low temperature and ensure the smooth output of crude oil. Oil pipelines pass through different geographical environments and face huge temperature differences. Electric heating cables are laid along the pipelines to maintain the fluidity of crude oil in the pipelines, whether in cold ground or underground environments. In terms of oil storage tanks, the electric heating system can be installed on the outer wall and top of the tank to prevent crude oil from stratifying or solidifying in the tank, and also prevent damage to the tank structure caused by temperature changes.

In the pharmaceutical industry, some production equipment needs to operate under strict temperature conditions to ensure the quality and purity of drugs. For example, equipment such as reactors, crystallizers, and large containers for storing pharmaceuticals often have complex internal structures and high-precision temperature requirements. Electric heating technology provides an ideal heating solution for these devices through precise temperature control. The self-limiting temperature electric heating belt can automatically adjust the power according to the actual temperature of the equipment, so that the chemical reaction in the reactor can be carried out at the optimal temperature, ensuring the quality of drug synthesis. For crystallizers, the appropriate electric heating temperature can control the crystallization speed and the quality of the crystals, meeting the strict requirements of the pharmaceutical process.

The advantages of electric heating in heating complex equipment are manifold. First, it is highly adaptable and can be flexibly configured according to the shape, structure and heating requirements of different equipment. Second, the temperature control accuracy of the electric heating system is high. Through advanced controllers and sensors, the temperature error can be controlled within a very small range, which is crucial for those temperature-sensitive equipment. Furthermore, the installation of electric heating is relatively simple and does not require large-scale modification of the existing equipment structure. It can be installed without affecting the normal operation of the equipment. In addition, electric heating has good safety and reliability during operation, reducing the potential safety hazards such as fire and explosion caused by traditional heating methods.

In short, the application of electric heating in the heating of complex equipment provides an efficient and reliable means of temperature assurance for industrial production, ensuring the normal operation of various equipment in low temperature environments, and plays an important role in improving production efficiency and product quality.
