Xinshao Photoelectric Thermal Group Co., Ltd. has an electrical appliance called explosion-proof electric heater, which is a device that can convert electrical energy into thermal energy and heat materials that need to be heated. It is the most common electric heating product in explosion-proof places. Then some people will have doubts, why are explosion-proof electric heaters used? Because in many chemical and dust sites, electrical machinery and equipment cannot meet the requirements, and explosion accidents may occur at any time. When explosive substances are mixed with oxygen in the air When the mixed concentration reaches the explosion limit, once there is an explosion source, an explosion will occur, and the consequences of the explosion will bring immeasurable losses and casualties to the enterprise. At this time, the explosion-proof electric heater will greatly play its role. come with me

1. Working principle: When the explosion-proof electric heater is working, it can enter its input port through a pipeline under pressure in a low-temperature fluid medium, and along its internal specific heat exchange channel, the path designed by the fluid theory is used to transfer the electric heating The high-temperature heat energy generated during the operation of the element is taken away, the temperature of the heated medium increases, and the outlet reaches the high-temperature medium required by the process. Its internal control system automatically adjusts the temperature of the medium at the output port according to the temperature sensor signal at the output port; and when the heating element is overheated, its independent overheat protection device will immediately cut off the power supply. This design is to prevent material deterioration and coking. Or carbonization, or even burn out the components in more serious cases, which will affect the service life of the electric heater.

The above is the working principle of explosion-proof electric heater. In addition to learning the principle of explosion-proof electric heater, I also found that the original explosion-proof electric heater is used in various places. Let me show you in batches.

Second, the application site of explosion-proof electric heater:

1. In the chemical industry

Chemical materials can be heated by heating and drying some powders under pressure

Explanation: Because the crushing of raw materials in the chemical industry will generate a large amount of dust, these dusts are collected into the dust removal room through the dust removal system and then reused. However, due to the dust generated by different raw materials, the moisture content will vary greatly. In the long run, these dusts are generally directly compressed and then reused. In the dust, when the moisture is too large, it will cause mildew and hardening during storage and transportation, which will make the treatment effect extremely poor and affect the quality of the product after secondary use. At the same time, the moisture content of the dust is too high. When the tablet machine presses the dust, it often occurs that the tablet machine is blocked, or even damages the tablet machine, which will shorten the service life of the equipment and affect the continuity of production. , resulting in low-quality products produced. In order to improve this problem, the use of Xinshao Photoelectric's new explosion-proof pipeline heater just solves this problem, not only the drying effect is good, but also the moisture content of different chemical dusts can be monitored in real time, and the quality and advantages of dust tableting can be guaranteed.

2. Explosion-proof electric heaters are used for heating hydrocarbons, including petroleum, crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.

Explanation: When different types of hydrocarbons are dried and heated, the heat transfer oil furnace is a commonly used oil-type explosion-proof electric heater.

3. Use in process water, superheated steam, molten salt, nitrogen (air), water gas and other fluid media that need to be heated.

Explanation: Process water includes drinking water, purified water, water for injection and sterilized water for injection. In the process water, we will use explosion-proof pipeline heaters. The superheated steam expands adiabatically when it passes through the steam turbine to convert thermal energy into mechanical energy. a process. Water gas is commonly used to smelt metals.

3. Features of explosion-proof electric heater:

Due to the advanced explosion-proof layout, the equipment can be widely used in various explosion-proof places such as chemical industry, military industry, oil, natural gas, offshore platforms, ships, and mining areas.
