Electric heater is an international popular electric heating equipment. It is used for heating, heat preservation and heating of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under the action of pressure, the principle of fluid thermodynamics is used to uniformly take away the huge heat generated by the electric heating element, so that the temperature of the heated medium can meet the user’s technological requirements. One of them is called explosion-proof electric heater. Let me explain it to you below:
Explosion-proof electric heater is a kind of consumption electric energy converted into heat energy to heat the material to be heated. During operation, the low-temperature fluid medium enters its input port through the pipeline under the action of pressure, along the specific heat exchange flow channel inside the electric heating container, and uses the path designed by the principle of fluid thermodynamics to take away the high-temperature heat energy generated by the electric heating element. The temperature of the heated medium is increased, and the high temperature medium required by the process is obtained from the outlet of the electric heater. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor signal at the output port, so that the temperature of the medium at 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 to avoid The overheating of the heating material will cause coking, deterioration and carbonization, and in severe cases, the heating element will be burned out, which effectively prolongs the service life of the electric heater.
Typical applications of explosion-proof electric heaters are:
1. The chemical materials in the chemical industry are heated by heating, some powders are dried under a certain pressure, chemical processes and spray drying.
2. Hydrocarbon heating, including petroleum crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Process water, superheated steam, molten salt, nitrogen (air) gas, water gas and other fluids that need to be heated.
4. Due to the 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.
Features
1. Small size and high power: the heater mainly adopts clustered tubular electric heating elements
2. The thermal response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high.
3. High heating temperature: The designed working temperature of the heater can reach 850℃.
4. The outlet temperature of the medium is uniform and the temperature control accuracy is high.
5. Wide application range and strong adaptability: The heater can be used in explosion-proof or ordinary occasions, the explosion-proof grade can reach dⅡB and C grades, and the pressure resistance can reach 20MPa.
6. Long life and high reliability: The heater is made of special electric heating materials, designed with low surface power load, and adopts multiple protections, which greatly increases the safety and life of the electric heater.
7. Fully automatic control: According to the requirements of the heater circuit design, it is convenient to realize automatic control of parameters such as outlet temperature, flow rate, pressure, etc., and can be networked with a computer.
8. The energy-saving effect is remarkable, and almost 100% of the heat generated by the electric energy is transferred to the heating medium.
Convert electrical energy into heat to heat objects. It is a form of electric energy utilization. Compared with general fuel heating, electric heating can obtain higher temperature (such as arc heating, the temperature can reach more than 3000 ℃), and it is easy to realize automatic temperature control and remote control, (such as car electric heating cup) can be used as required. The heated object maintains a certain temperature distribution. Electric heating can directly generate heat inside the heated object, so it has high thermal efficiency and fast heating rate, and can realize overall uniform heating or local heating (including surface heating) according to the heating process requirements, and it is easy to realize vacuum heating and controlled atmosphere heating. In the process of electric heating, less waste gas, residue and smoke are generated, which can keep the heated object clean and does not pollute the environment. Therefore, electric heating is widely used in the fields of production, scientific research and testing. Especially in the manufacture of single crystals and transistors, mechanical parts and surface quenching, smelting of iron alloys and the manufacture of artificial graphite, electric heating methods are used.
According to the different ways of electric energy conversion, electric heating is usually divided into resistance heating, induction heating, arc heating, electron beam heating, infrared heating and medium heating.
