Fluid Explosion-Proof Electric Heater
Fluid explosion-proof electric heater is a device that consumes electrical energy and converts it into heat energy to heat the materials that need to be heated. During operation, the low-temperature fluid medium enters its input port through a pipeline under pressure, flows along a specific heat exchange channel inside the electric heating container, which is designed based on the principles of fluid thermodynamics, and carries away the high-temperature thermal energy generated by the electric heating elements during operation, thereby raising the temperature of the heated medium. The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power of the electric heater based on the temperature sensor signal at the outlet, ensuring uniform temperature of the medium at the outlet. When the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing the heated material from overheating, which could cause coking, deterioration, or carbonization, and in severe cases, damage the heating element, effectively extending the service life of the electric heater.Typical applications of fluid explosion-proof electric heaters mainly include:
1. Heating and temperature raising of chemical materials in the chemical industry, drying of some powders under certain pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids that need to be heated.
4. Zone 1 and Zone 2 hazardous gas locations;
5. Explosive gas or vapor atmospheres of Group IIA, IIB, T1 to T4;
6. Due to the advanced explosion-proof structure, the equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion protection.
Main Uses in the 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 developed based on advanced foreign electric heater technology, which provides high-voltage thermal energy. This electric heating furnace is a working method that uses electrical energy as the power source to convert its internal high-voltage voltage system into thermal energy.Generally speaking, the explosion-proof electric heating furnace uses heat transfer oil as the heat carrier. The internal high-voltage voltage system forces the heat transfer oil through the circulation pump with electrical energy, transferring the heat from the internal high-voltage voltage to one or more electric heating devices. After passing through the transition function of the high-voltage voltage system in the electric heating device, the heat transfer oil starts a new heating work cycle, i.e., it returns to the electric heating furnace through the circulation pump to absorb heat again and transfer it to the internal high-voltage voltage system of the electric heating furnace. Through this cyclic work, the electric heating furnace continuously transfers heat, enabling the internal high-voltage voltage system of the electric heating furnace to obtain a continuous high-temperature energy source, thus meeting the heating requirements of the heating medium during high-temperature processes.
Explosion-proof electric heater The characteristics of the mechanical electric heating industry are as follows:
1. It can achieve continuous transfer of the internal high-voltage voltage system, ensuring that the internal high-voltage voltage system of the electric heating device 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. 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 intelligent standards. The relevant technical personnel of China Electric Heater Network adopt an advanced intelligent heating working mode, i.e., by setting the original temperature of the high-voltage voltage medium inside the gas electric heater during work. 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 of the heater to the DCS system, and can also receive automatic and shutdown operation commands from the DCS. Moreover, reliable and safe monitoring devices have been added to the electric heater system, but 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 the heat transfer oil, and pressure of the internal high-voltage voltage, thereby achieving an ideal reform of the explosion-proof electric heater that is more energy-saving, environmentally friendly, and efficient.
