Explosion-proof electric heaters are usually used in situations where there is a risk of explosion, because there are various flammable and explosive oils, gases, dusts, etc. in the surrounding environment. If it touches an electric spark, it will cause an explosion, so an anti-drying electric heater must be used for heating in other occasions. The key explosion-proof measure of the explosion-proof electric heater is to have a drying device in the junction box of the electric heater to remove the safety hazard caused by electric sparks. For different heating occasions, the explosion-proof grades of electric heaters are also different, depending on the details.
The common application occasions of explosion-proof electric heaters are the heating and heating of chemical materials in the chemical industry, some powder drying under certain pressure, chemical process and spray drying. Hydrocarbon heating, including petroleum crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, stone, etc.; process water, superheated steam, molten salt, nitrogen (air), water gas and other fluids that need to be heated Because of the excellent explosion-proof structure, the machinery and equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, etc. where explosion-proof is required.
The structure type, the marine explosion-proof electric heater adopts the optimized composite design concept, so that the heat transfer is sufficient and the heat loss is significantly reduced. Electric heaters have the advantages of energy saving, safety protection, explosion-proof, intelligent temperature control, and compact space occupation. Under the premise of ensuring the same flow setting temperature for heating, the thermal efficiency of traditional electric heaters is increased by 20%~25%, the heat loss is reduced by 35%, and the safety factor against dry burning is increased by 30%. Enables continuous transmission of the internal high temperature voltage system. Ensure that the high temperature voltage system inside the electric heating equipment uses electric energy to obtain higher temperature power energy.
Meet the high temperature heating requirements of the medium during work tasks, so that its effect can be fully exerted.
The electric heater machine equipment has the advantages of precise structure, light volume, light weight and convenient installation process. When heating, it will not cause injury and pollution to the surrounding environment, and can obtain very high heating temperature and efficiency under relatively low working pressure. The internal high-voltage system can provide the DCS system with alarm signals such as heater operation, high temperature, failure, and shutdown, and can also accept the operation slogans such as automatic and shutdown issued by DCS. The monitoring device, but the price of other electric heaters is relatively high. It can effectively monitor the heat transfer oil pump, the temperature flow of the heat transfer oil, and the pressure of the internal high temperature voltage at any time.
