Description

Technical Field

[0001] The utility model relates to the technical field of special gas pipeline heating, and in particular to a heating device and a system for special gas pipelines. Background Art

[0002] In modern industrial production and daily life, pipelines are widely used in the fields of petroleum, chemical industry, electricity, medicine, food, etc. to transport liquids or gases. In order to meet specific process requirements or improve efficiency, ensure the effective flow of the medium and prevent solidification or increase in viscosity due to low temperature, it is often necessary to heat the medium in the pipeline.

[0003] Traditional pipeline heating methods include the use of electric heating tapes, hot water or steam heating, etc. Electric heating tapes heat the pipeline by directly wrapping a resistance wire around the outside of the special gas pipeline and generating heat when powered on. This method is easy to install, but the heat is easily lost, the heating efficiency is low, and the resistance wire is directly exposed, which poses a major safety hazard. Hot water heating heats the pipeline by circulating hot water. This method is environmentally friendly and low-cost, but the heating speed is slow and is limited by the temperature of the heat source, so it is not suitable for high-temperature heating needs. Steam heating uses the high temperature of steam to heat the pipeline. This method has a fast heating speed and high efficiency, but requires additional steam generation equipment, which increases the complexity and cost of the system.

[0004] With the advancement of science and technology and the development of the industry, traditional pipeline heating devices can no longer meet the growing performance requirements. Some heating devices have appeared in the prior art, such as setting a pipe body, setting a heating resistor wire in the pipe body, and setting a conveying channel. The equipment is not only simple but also highly safe. However, this heating device is not flexible and convenient to install and disassemble, cannot monitor the temperature inside the heating device, does not have a heat preservation function, and heat is easily lost. At the same time, it does not have the function of timely heat dissipation. When heating is not needed, the cooling is slow and the cooling time is long.

[0005] In view of the problems in the related technology, such as the heating device is not flexible and convenient to install and disassemble, does not have a real-time temperature monitoring device, heat is easily lost, and the cooling is slow, no effective solution has been proposed.
