The explosion-proof electric heater heat conduction characteristics and uses

The explosion-proof electric heater furnace (organic heat carrier furnace) is based on the absorption of foreign advanced technology, a new type of safety, high efficiency, low voltage, high temperature heat energy can supply special explosion-proof industrial furnace developed.

The furnace is a kind of electric heating source, that is, the tubular heating element immersed in the heat conducting oil generates electricity by electricity. The heat conduction oil is used as the heat carrier, and the heat pump is forced to circulate through the hot oil circulation pump to transmit heat to one or more thermal equipment. When the heat equipment is unloaded, the heat conducting oil passes through the circulating pump and goes back to the electric heating furnace, and then absorbs heat to the thermal equipment. So it completes the successive transmission of heat through cycle. Ensure the use of heat equipment to obtain continued and stable high temperature power. The technical requirement of satisfactory medium heating. Can choose the digital temperature control furnace temperature control instrument, with over temperature alarm and alarm, ultra low oil pressure alarm function. It also has safety measures for preventing dry burning and explosion protection. Explosion-proof heater explosion-proof grade is ExdIIBT4, ExdIIBT6, ExdIICT6 and so on.

Equipment features:

The equipment is compact in layout, small in size, light in weight and simple in operation of equipment. There is no pollution when heating, and it can obtain higher working temperature under lower working pressure.

With a high degree of initiative, a leading active temperature control system is chosen, that is, through the set temperature feedback to the control system to complete the active conditioning of the heat load. Using the manipulating technology with fuzzy control and self - tuning PID control, the temperature control accuracy can reach to + 1 - 0.1 and even more accurate. And it can be connected with the computer to implement the human-computer dialogue. The control system can provide the heater with signal in operation, over temperature, stop, temperature signal and interlocking condition to the DCS system, and it can withstand the proactive and aborted operation instructions announced by DCS. And a reliable safety monitoring equipment has been added.

Such as: conventional electrical maintenance, leakage maintenance, short circuit maintenance, and so on. There are multiple interlocking interfaces, which can be used to monitor the oil pump, flow and pressure at any time. It has a set of independent temperature control alarm system which is independent of normal temperature control. When a temperature control is out of control due to various reasons, the system can not only alarm in time, but also can not reset the electric heater, so as to ensure the safe operation of the system. And enter the contact signal.

Equipment layout is reasonable, technical and sophisticated, complete matching, short equipment cycle, convenient operation and repair, safe and reliable, wide range of application.

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

Main uses: used in petrochemical, oil and oil materials, building materials industry, textile printing and dyeing, food, plastic, rubber, pharmaceutical and so on.
