Description

Technical Field

[0002] Explosion-proof thermal oil heater is an industrial equipment used for heating. It converts electrical energy into thermal energy through electric heating elements, transfers it to thermal oil, and then transports the heat to the equipment or medium that needs to be heated through a circulation system.

[0003] Thermal oil may undergo thermal cracking reaction when running at high temperature for a long time, producing low-flash-point oligomers. These substances may further undergo polymerization reaction to generate polymers. The accumulation of polymers will not only reduce the fluidity of oil products and affect the heat transfer efficiency, but also may cause local overheating of pipelines, increasing the risk of pipeline deformation or bursting. Existing explosion-proof thermal oil heaters lack temperature detection devices, resulting in inaccurate control of internal temperature. If cracks occur in the device and internal thermal oil leaks, it may not be discovered in time, causing the internal thermal oil to leak completely and cause waste. In addition, thermal oil may produce harmful substances when it comes into contact with oxygen under high temperature conditions.
