The working principle and function features of explosion-proof electric heater

Editing principle of explosion proof electric heater:

The utility model relates to a fluid explosion-proof electric heater, which is used for heating materials by converting electric energy consumption into heat energy. 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.

Typical applications of explosion-proof electric heater are mainly:

The chemical material of chemical industry, under certain pressure heating heating powder drying, spray drying and chemical process.

The hydrocarbons including crude oil, heating oil, fuel oil, heavy oil, thermal oil, lubricating oil, paraffin wax etc.

3 process water, superheated steam, molten salt, nitrogen (air) gas, water gas and so on for heating the heating fluid.

Due to the adoption of the explosion-proof structure of advanced equipment can be widely applied to places in the explosion-proof chemical industry, petroleum, natural gas, offshore platform, shipbuilding, mining etc..

Functional characteristics

The small volume, large power heater: mainly uses the cluster type tubular electric heating element

The fast response, high precision, high comprehensive heat efficiency.

3 high heating temperature heater design: maximum working temperature is 850 degrees centigrade.

The outlet temperature of the homogeneous medium, high precision of temperature control.

The application of a wide range of adaptability, the heater can be applicable to explosion-proof or ordinary occasions, explosion-proof grade up to D grade and C grade II B, voltage up to 20MPa.

The long service life, high reliability, the heater is made of special electric materials, the design of surface power load is low, and the use of multiple protection, the electric heater safety and greatly increased the life.

The automatic control: according to the requirement by the heater circuit design, automatic control parameters can facilitate the realization of outlet temperature, flow and pressure, and computer network.

The energy-saving effect of electricity heat generated by the heating medium to almost 100%.

Convert electric energy into heat energy to heat objects. It is a form of electrical energy utilization. Compared with the general fuel heating, electric heating can obtain higher temperature (such as electric arc heating, the temperature can reach more than 3000 DEG C), automatic control and remote control to achieve the temperature (such as vehicle, electric heating cup) can according to the needs of the heated object to maintain certain temperature distribution. Electric heating can be heated in the heat inside the object directly, and high thermal efficiency, fast heating speed, and according to the requirements of the heating process, to achieve the overall uniform heating or heating (including surface heating), easy to implement and control the heating heating in vacuum atmosphere. In the process of electric heating, the waste gas, the residue and the smoke and dust are less, and the cleaning of the heated object can be kept, and the environment is not polluted. Therefore, electric heating is widely used in the fields of production, scientific research and experiment. Electrical heating is adopted, especially in the manufacture of single crystals and transistors, mechanical parts and surface hardening, melting of iron alloys, and fabrication of synthetic graphite.

According to the different modes of electric energy conversion, electric heating is usually divided into resistance heating, induction heating, arc heating, electron beam heating, infrared heating and dielectric heating, etc..
