The characteristics of the explosion proof electric heater and what is the application industry

The explosion-proof heater is a new type of explosion-proof industrial furnace developed on the basis of absorbing advanced technology at home and abroad, which is energy efficient, new and safe, and can provide high temperature heat energy. The industrial furnace is a kind of electric energy source, which is heated by tubular electric heating elements immersed in the heat conducting oil, and then generates heat by heat. Then the heat conduction oil is used as the heat carrier. After that, the heat pump is forced to circulate, and heat is transferred to one or more thermal equipment.

When the heat equipment is unloaded, the heat conducting oil must be reused through the circulating pump, then go back to the electric heating furnace, then absorb heat and transmit it to the thermal equipment, so that the continuous heat transfer can be realized. Ensure that the heat equipment can be used to obtain stable and stable high temperature energy. Meet the technical requirements of medium heating.

Equipment features:

The equipment is compact in structure, small in size, light in weight, and easy to install and operate. There is no pollution when heating, and it can get higher working temperature under lower working pressure.

High automation, the use of advanced automatic temperature control mode, that is, through the set of temperature feedback to the control system to realize the automatic regulation of heat load. The control technology with a perfect combination of fuzzy control and self tuning PID control can reach a temperature control accuracy of + 1 to + 0.1, or even more accurate. And it can be connected with the computer to carry out human-computer dialogue. The control system can provide the DCS system with signals such as heater running, over temperature, stop, temperature signal, interlock state and so on, so that it can accept automatic and stop operation commands issued by DCS. And a reliable safety monitoring device is set up. Such as:

Conventional electrical protection, leakage protection, short circuit protection and so on.

There are multiple interlocking interfaces to monitor the oil pump, flow and pressure at any time.

There is a set of independent temperature alarm system which is independent of normal temperature control. When a conventional temperature control is out of control due to various reasons, the system can alarm not only in time, but also can turn off the electric heater without reclosing, so as to ensure the safe operation of the system. And enter the contact signal.

The heat utilization rate is high, the efficiency of energy saving is remarkable, and the operation cost is low and the recovery investment is fast.

In short, the fluid explosion-proof electric heater is a kind of equipment used in explosion-proof occasions to convert electricity into thermal energy. It is used to heat, heat and heat the liquid, gaseous and solid medium of flow or stationary.

Chemical industry materials heating and heating, some powder drying, chemical process and spray drying under certain pressure.

Hydrocarbon heating, including oil crude oil, heavy oil, fuel oil, heat conduction oil, oil, stone wax, etc.

Process water, superheated steam, molten salt, nitrogen (air) gas, water gas and so on, and so on.

Because of the advanced explosion-proof structure, the equipment can be widely applied to chemical industry, military industry, petroleum, natural gas, offshore platforms, ships and mining areas.

Functional characteristics:

Small volume and high power: the heater mainly uses a cluster tubular electric heating element.

The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high.

The heating temperature is high: the heater can be designed for the highest working temperature of 850 degrees C.

The temperature of the medium is uniform and the precision of temperature control is high.

Wide application and strong adaptability: the heater can be applied to explosion-proof or ordinary occasions, explosion-proof grade can reach D II B grade and C grade, and the pressure can be up to 20MPa.

Long life and high reliability: the heater is made of special electrothermal material, and its surface power load is low, and multiple protection is adopted, so that the safety and life of electric heater will be greatly increased.

Fully automatic control: according to the requirement, through heater circuit design, it can realize automatic control of outlet temperature, flow and pressure and so on, and it can be networked with computer.

The energy saving effect is remarkable, the energy produced by electric energy is almost 100% to the heating medium.
