Main uses of mechanical electric heating industry
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 on the basis of advanced foreign electric heater technology. 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 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 of the high-voltage temperature system in the electric heating equipment, the heat transfer oil starts a new heating work efficiency, that is, it returns to the electric heating furnace through the circulation pump again to absorb heat for the second time and transmit it to the internal high-voltage temperature system of the electric heating furnace. Through this cyclic work, the electric heating furnace continuously transfers heat, so that the internal high-voltage temperature system of the electric heating furnace can obtain a continuous high-temperature energy source, thereby meeting the heating requirements of the heating medium during the high-temperature process.
The characteristics of explosion-proof electric heaters in the mechanical electric heating industry are as follows:
1. It can realize continuous transmission 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 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, light volume, light weight, and convenient installation. During heating, it does not cause pollution to the surrounding environment, and can achieve relatively high heating temperature and efficiency under relatively low working pressure.
3. High level of intelligence. Relevant technical personnel of China Electric Heater Network adopt advanced intelligent heating working mode, that is, by setting the original temperature in the working process 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 DCS. Moreover, a reliable and safe monitoring device is added to the electric heater system, but the price 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 at any time, thereby achieving an ideal reform of explosion-proof electric heater that is more energy-saving, more environmentally friendly, and more efficient.
