Explosion proof heater is one of the international popular electric heating equipment with high quality and long life. Used for warming, holding and heating a flowing liquid or gaseous medium. When the heating medium through the electric heating chamber under pressure, the fluid thermodynamics principle even take huge heat generated by the heating element in the work of the heating medium temperature reaches the requirement of customers.
An explosion proof electric heater is a kind of electric energy that is consumed and converted into heat energy to heat the material to be heated. 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 editor
Explosion-proof heater generally used for dangerous situations due to the presence of potentially explosive, flammable and explosive environment of oil, gas, dust, once exposed to electric spark can cause an explosion, so in this case requires the use of explosion-proof heater heating. The main explosion-proof measure of the explosion-proof heater is that there is a flameproof device in the junction box of the heater, so as to eliminate the hidden danger of the electric spark explosion. For different heating occasions, the heater explosion-proof grade requirements are different, depending on the specific circumstances.
Typical applications of explosion-proof electric heaters are:
1，chemical material heating, heating, some powder drying under certain pressure, chemical process and spray drying.
2, hydrocarbon heating, including oil, crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin and so on
3, process water, superheated steam, molten salt, nitrogen (air) gas, water gas and so on, need to warm up heating fluid heating.
4, because of the use of advanced explosion-proof structure, the equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, such as the need for explosion-proof sites.
