Main uses of mechanical electric heating industry
The 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 the technical level of advanced foreign electric heaters. This electric heating furnace is a working method that uses 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 the forced processing of electrical energy, transfers the heat of the internal high-voltage temperature to one or more electric heating equipment. After passing through the transition function in the high-voltage temperature system of the electric heating equipment, the heat transfer oil starts a new heating work efficiency, that is, through the circulation pump again, returns to the electric heating furnace for secondary heat absorption and transfers the heat to the internal high-voltage temperature system of the electric heating furnace. Through this cyclic work, the electric heating furnace continuously transfers heat, enabling the internal high-voltage temperature system of the electric heating furnace to obtain a continuous high-temperature energy source, thereby meeting the heating requirements of the heating medium during the high-temperature process.
The characteristics of the explosion-proof electric heater 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 uses electrical energy to obtain a higher temperature energy source, 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 process. During heating, it does not cause harmful pollution to the surrounding environment, and can obtain relatively high heating temperature and efficiency under relatively low working pressure.
3. High intelligent standard. The relevant technical personnel of China Electric Heater Network adopt an advanced intelligent heating working mode, that is, 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 of the heater to the DCS system, and can also accept automatic and shutdown operation commands issued by the DCS. Moreover, a reliable and safe monitoring device is added to the electric heater system, but the price reference of this electric heater is relatively high.
5. The electrical equipment has multiple related interfaces, which can effectively monitor the heat transfer oil pump, the temperature and flow of the heat transfer oil, and the pressure of the internal high-voltage temperature, thereby achieving the ideal reform of explosion-proof electric heater that is more energy-saving, more environmentally friendly, and more efficient.
