Explosion-proof electric heater is a kind of equipment used in explosion-proof occasion to convert electric power into heat energy. Used for heating, holding and heating liquid, gaseous and solid media flowing or stationary.

Fluid explosion-proof electric heater is a kind of energy-consuming converter to heat energy to heat the materials that need to be heated. In the work, the low-temperature fluid medium enters its input port through the pipeline under the action of pressure, along the specific heat transfer channel inside the electric heating vessel, using the path designed by the principle of fluid thermodynamics, takes away the high-temperature heat energy generated in the work of the electric heating element, makes the temperature of the heated medium rise, and the outlet of the electric heater obtains the high-temperature medium required by the technology. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor signal of the output port, so that the medium temperature of the output port is uniform; when the heating element is overheated, the independent overheating protection device of the heating element immediately cuts off the heating power supply, avoiding the coking, deterioration and carbonization caused by the overtemperature of the heating material, and causing the burning of the heating element in serious cases, effectively prolonging the electricity supply. Service life of heater.

Typical applications of fluid explosion-proof electric heaters include:

1. Application in chemical industry of air electric heater, heating of chemical material, drying of powder under certain pressure, chemical process and spray drying.

2. Hydrocarbon heating, including petroleum crude oil, heavy oil, fuel oil, heat conducting oil, lubricating oil, paraffin, etc.

3. Process water, superheated steam, molten salt, nitrogen (air) gas, water gas and other fluids that need heating.

4. Because of the advanced explosion-proof structure, the equipment can be widely used in chemical industry, military industry, petroleum, natural gas, offshore platforms, ships, mining areas and other places requiring explosion-proof.

Compared with ordinary heaters, the advantages of air electric heaters are obvious:

1. The field operation box and equipment of the air electric heater are combined into a whole pry block to be installed in zone 2 explosion-proof * electric heater: indoor or outdoor installation, non-corrosive

2. Functional characteristics of air electric heater in explosion-proof zone 2. 1. Small size and high power: air electric heater mainly uses cluster tubular electrothermal elements.

3. The air electric heater has fast thermal response, high temperature control precision, high comprehensive thermal efficiency, and the heating temperature of the air electric heater must be high: the high working temperature of the heater design can reach 850 C.

4. The outlet temperature of the medium in the air electric heater is uniform and the temperature control precision is high.

5. Wide application and strong adaptability: The air electric heater can be applied to explosion-proof or common occasions. The explosion-proof grade of the air electric heater can be up to class D II B and C, and the withstand voltage can be up to 20 MPa.

6. Long life and high reliability: The air electric heater is made of special electrothermal materials. The designed surface power load is low and multiple protection is adopted, which greatly increases the safety and life of the air electric heater.

7. Fully automatic control: According to the requirements, through the circuit design of the air heater, it can easily realize the automatic control of the outlet temperature, flow rate, pressure and other parameters of the air heater, and can be connected with the computer.

8. The energy-saving effect of the air electric heater is remarkable. The heat generated by electric energy is almost 100% transferred to the heating medium of the air electric heater.
