Fluid Explosion-Proof Electric Heater

Fluid explosion-proof electric heater is a device that converts electrical energy into thermal energy to heat the material to be heated. During operation, the low-temperature fluid medium enters the input port under pressure through the pipeline, flows along the specific heat exchange channel inside the electric heating container, following the path designed based on fluid thermodynamics principles, 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 provides the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power based on the temperature sensor signal at the outlet, ensuring uniform medium temperature at the outlet. When the heating element overheats, the independent overheat protection device immediately cuts off the heating power supply, preventing the heated material from overheating, coking, deteriorating, or carbonizing, which could otherwise damage the heating element, effectively extending the service life of the electric heater.

Application Scope

Typical applications of fluid explosion-proof electric heaters mainly include:
1. Heating of chemical materials in the chemical industry, drying of certain powders under 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. Process water, superheated steam, molten salt, nitrogen (air), water gas, and other fluids requiring heating.
4. Hazardous gas locations in Zone 1 and Zone 2;
5. Explosive gas or vapor environments of Groups IIA and 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-proof measures.

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 for high-voltage thermal energy, developed based on advanced foreign electric heater technology. This electric heating furnace operates by using electrical energy as the power source to convert the 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 by electrical energy, delivers 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 cycle, i.e., it returns through the circulation pump to the electric heating furnace to absorb heat again and transmit it to the internal high-voltage temperature system. Through this cyclic operation, the electric heating furnace continuously transfers heat, enabling the internal high-voltage temperature system to obtain a sustained high-temperature energy source, thereby meeting the heating requirements of the heated medium during high-temperature processes.
Explosion-proof electric heater has the following characteristics in the mechanical electric heating industry:
1. It 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 a high-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, small volume, light weight, and easy installation. 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 intelligence. 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 temperature medium inside the gas electric heater during operation. 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, a reliable and safe monitoring device is added to the electric heater system. However, the price of this electric heater is relatively high.
5. The electrical equipment has multiple associated interfaces, allowing effective monitoring of the heat transfer oil pump, temperature and flow of the heat transfer oil, and internal high-voltage pressure at any time, thereby achieving more energy-saving, environmentally friendly, and efficient ideal reforms for the explosion-proof electric heater.
