Main applications in the mechanical electric heating industry:
Explosion-proof electric heater is a high-efficiency, energy-saving, environmentally friendly, and safe explosion-proof industrial electric heating furnace for high-voltage thermal energy, developed based on advanced foreign electric heater technology. This electric heating furnace uses electricity as the power source to convert its internal high-voltage voltage system into thermal energy.
Generally speaking, the explosion-proof electric heating furnace uses thermal oil as the heat carrier. The internal high-voltage voltage system, through the circulation pump of the thermal oil and forced processing by electric energy, transfers the heat of the internal high-voltage voltage to one or more electric heating devices. After passing through the transition function in the high-voltage voltage system of the electric heating device, the thermal oil starts a new heating work cycle, i.e., it returns through the circulation pump to the electric heating furnace to absorb heat again and transfer it to the internal high-voltage voltage system of the electric heating furnace. Through this cyclic operation, the electric heating furnace continuously transfers heat, allowing its internal high-voltage voltage system to obtain a sustained high-temperature energy source, thereby meeting the heating requirements of the heating medium during high-temperature processes.
The characteristics of explosion-proof electric heaters in the mechanical electric heating industry are as follows:
1. It can achieve uninterrupted transfer of the internal high-voltage voltage system, ensuring that the electric heating equipment's internal high-voltage voltage system uses electrical energy to obtain higher temperature energy, meeting the high-temperature heating requirements of the medium during operation and maximizing its effect.
2. This equipment has a precise structure, small volume, light weight, and is easy to install. During heating, it does not produce harmful pollution to the surrounding environment and can achieve relatively high heating temperatures and efficiency at relatively low working pressures.
3. High level of intelligence. Relevant technical personnel from China Electric Heater Network have adopted an advanced intelligent heating working mode, i.e., by setting the original temperature during operation through the high-temperature voltage medium inside the gas electric heater. In experiments, this temperature control accuracy can reach a range of ±2°C to ±0.2°C.
4. The internal high-voltage system of this equipment can provide alarm signals such as operation, high temperature, fault, and shutdown to the DCS system, and can also receive automatic and shutdown operation commands from the DCS. Moreover, a reliable and safe monitoring device has been added to the electric heater system. However, the price reference for this electric heater is relatively high.
5. The electrical equipment has multiple associated interfaces, allowing effective monitoring of the thermal oil pump, thermal oil temperature and flow, and internal high-voltage voltage pressure at any time. This achieves the ideal improvement of the explosion-proof electric heater to be more energy-saving, environmentally friendly, and efficient.
