Main Uses of the Mechanical Electric Heating Industry
Explosion-proof electric heaters are a type of efficient, energy-saving, environmentally friendly, and safe explosion-proof industrial electric heating furnace developed based on advanced foreign electric heater technology, providing high-voltage thermal energy. This electric heating furnace operates by using electrical energy as a power source to convert its internal high-voltage temperature system into thermal energy.
Generally speaking, an explosion-proof electric heating furnace uses thermal oil as a heat carrier. The internal high-voltage temperature system, through the circulation pump of the thermal oil and forced processing by electrical energy, transfers the heat from the internal high-voltage temperature to one or more electric heating devices. After passing through the transition function in the high-voltage temperature system of the electric heating device, the thermal oil begins a new heating work cycle, i.e., it returns through the circulation pump to the electric heating furnace to absorb heat a second time and transmit it to the internal high-voltage temperature system of the electric heating furnace. Through this cyclic operation, the electric heating furnace continuously transfers heat, allowing its internal high-voltage temperature 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. They can achieve uninterrupted transfer of the internal high-voltage temperature system, ensuring that the internal high-voltage temperature system of the electric heating device 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 cause harmful pollution to the surrounding environment and can achieve relatively high heating temperatures and efficiency at relatively low working pressures.
3. High level of intelligent standards. 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-voltage temperature medium inside the gas electric heater. In experiments, this temperature control accuracy can reach a range of ±2℃ to ±0.2℃.
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 accept automatic and shutdown operation commands from the DCS. Moreover, reliable and safe monitoring devices have been added to the electric heater system. However, the price of this electric heater is relatively high.
5. The electrical equipment has multiple related interfaces, allowing effective monitoring of the thermal oil pump, thermal oil temperature and flow, and internal high-voltage pressure at any time. This achieves the ideal reform of explosion-proof electric heaters to be more energy-saving, environmentally friendly, and efficient.
