Main Uses in the Mechanical Electric Heating Industry
The explosion-proof electric heater is an efficient, energy-saving, environmentally friendly, and safe explosion-proof industrial electric heating furnace for high-voltage thermal energy, developed based on the advanced technical level of foreign electric heaters. 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, the explosion-proof electric heating furnace uses heat transfer oil as the heat carrier. The internal high-voltage temperature system, through the circulation pump of the heat transfer oil and forced processing of 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 heat transfer oil begins a new heating work efficiency, i.e., it returns to the electric heating furnace through the circulation pump 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, enabling the internal high-voltage temperature system to obtain sustained high-temperature energy, 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 continuous transfer of the internal high-voltage temperature system, ensuring that the internal high-voltage temperature system of the electric heating equipment obtains higher temperature energy using electrical energy, meeting the high-temperature heating requirements of the medium during operation, and maximizing its effect.
2. This equipment has a precise structure, light volume, light weight, and convenient installation. It does not cause harmful pollution to the surrounding environment during heating 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 adopt 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 issued by the DCS. Moreover, reliable and safe monitoring devices have been added to the electric heater system. However, the price reference for this type of electric heater is relatively high.
5. The electrical equipment has multiple related interfaces, allowing effective monitoring of the heat transfer oil pump, temperature and flow of heat transfer oil, and internal high-voltage temperature pressure, thereby achieving an ideal reform of explosion-proof electric heaters that is more energy-saving, more environmentally friendly, and more efficient.
