Widely used in petroleum, chemical, pharmaceutical, textile, food processing and other industries. It converts electrical energy into thermal energy, and then transfers the heat to the medium or equipment that needs heating through thermal oil. This article will introduce the working principle, structural characteristics, application fields and usage precautions of thermal oil electric heater in detail.
Working Principle
The main working principle of thermal oil electric heater is as follows:
Electrical energy converted into thermal energy: The electric heater is equipped with resistance wires inside. When current passes through the resistance wires, according to Joule's law, the resistance wires generate heat.
Thermal oil circulation: The generated heat is transferred to the thermal oil through the metal sheath. The thermal oil circulates in the system under the action of the pump, transferring the heat to the medium or equipment that needs heating.
Temperature control: Through temperature sensors and controllers, the temperature of the thermal oil is monitored and adjusted in real time to ensure the stability and safety of the heating process.
Structural Characteristics
Electric heating element: Usually uses resistance wire as the heating element, with efficient and stable heating performance.
Thermal oil system: Includes thermal oil pump, heat exchanger, expansion tank and other components to ensure the circulation of thermal oil and the transfer of heat energy.
Temperature control system: Equipped with temperature sensors and controllers to achieve precise control of the heating temperature.
Safety protection devices: Including overheat protection, overpressure protection, leakage alarm, etc., to ensure the safe operation of the equipment.
Shell and insulation layer: Made of high-quality materials, the shell and insulation layer reduce heat loss and improve energy efficiency.
Application Fields
Petroleum and chemical industry: Used for heat tracing of crude oil pipelines, heating and insulation of reactors, temperature control of chemical reactions, etc.
Pharmaceutical industry: Used for temperature control in drug synthesis, extraction, concentration and other processes.
Textile industry: Used for heating of dyeing machines, setting machines and other equipment.
Food processing: Used for heating in food drying, sterilization, cooking and other processes.
