Analysis of the working principle of explosion proof electric heater and the principle of explosion proof

The explosion-proof electric heater is usually used for risk situations where explosion can happen. Because there are flammable and explosive oil, gas and dust in the surrounding environment, once the electric spark is touched, it will cause the explosion. Therefore, it is necessary to choose an explosion-proof electric heater for heating in such an environment.

The first explosion proof method of the explosion proof electric heater is that there is a flameproof device in the connection box of the heater to eliminate the risk of detonating by the electric spark. On different heating occasions, the heater's explosion-proof grade needs to be different, depending on the specific conditions. Explosion-proof electric heaters are common applications:

Chemical materials in chemical industry are heating up, some powder is monotonous, chemical process and jet are monotonous under certain pressure.

Hydrocarbon heating, including oil crude oil, heavy oil, fuel oil, heat conduction oil, oil, stone wax, etc.

Water, superheated steam, molten salt, nitrogen (empty) gas, water gas and so on, and so on.

Due to the selection of the prior explosion-proof plan, the equipment can be widely used in chemical industry, military industry, petroleum, natural gas, marine way, ship and mining area.

Explosion-proof electric heater is an international popular high quality long life electric heating equipment. It is used to heat, heat and heat the liquid and gaseous media of the flow. When the heating medium is under pressure, the heating chamber is heated through the electric heater, and the huge heat generated by the working of the electric heating element is uniformly carried out by using the fluid thermodynamics principle, so that the temperature of the heated medium reaches the user's technological requirement. The principle of explosion proof electric heater and the principle of explosion protection are introduced.

The working principle of explosion-proof heater:

Explosion-proof electric heater is a kind of electric energy conversion to heat energy, to heat the heating material. In the work of low temperature fluid through a pipe under pressure into the input port, along the electric heating container specific heat flow path using fluid thermodynamic principle, take heat energy generated in the heating element, the heating medium temperature, high temperature medium electric heater export process requirements. The electric heater internal control system according to the automatic regulation of the heater power output temperature sensor signal output port, the output port of the uniform medium temperature; when the heating element overheating, overheating protection device independent of the heating element immediately cut off the heating power, heating the material to avoid overheating caused by coking, metamorphism, carbonization, leading to severe fever element burn, prolong the service life of the electric heater.

Explosion proof principle of explosion-proof heater:

The explosion-proof electric heater is usually used for dangerous occasions where explosion is possible. Because there are flammable and explosive oil, gas and dust in the surrounding environment, once the electric spark is touched, it will cause an explosion, so heating in this area requires an explosion-proof heater. The main explosion-proof measure of the explosion proof heater is that there is a flameproof device in the connection box of the heater to eliminate the hidden danger of the detonating by the electric spark. For different heating occasions, the heater's explosion-proof grade requirements are also different, depending on the specific conditions.
