Explosion-proof electric heating heat conduction oil furnace

Explosion-proof electric heating heat transfer oil furnace (organic heat carrier furnace) is a new type of safe, energy-saving, high efficiency, low pressure, can provide high temperature heat energy special explosion-proof industrial furnace. The furnace is based on electric energy as the heat source, that is, the tubular electric heating element immersed in the thermal oil generates heat, and the thermal oil is used as the heat carrier, and the heat is transmitted to one or several thermal equipment through the hot oil circulation pump for forced circulation. When the thermal equipment is unloaded, the thermal oil will be re-through the circulation pump, back to the electric heating furnace to absorb heat transfer to the thermal equipment, so repeat, to achieve continuous transfer of heat, to ensure that the thermal equipment can be used to obtain continuous and stable high temperature energy, to meet the process requirements of medium heating.

The heat conduction oil furnace can be controlled by digital display temperature controller, which has the functions of over-temperature alarm, low oil level alarm and over-pressure alarm. And has anti-dry burning and explosion-proof safety measures. Explosion-proof heater explosion-proof grade for ExdIIBT4, ExdIIBT6, ExdIICT6 and so on.

Equipment features:

1, the equipment has a compact structure, small size, light weight, easy installation and operation. No pollution during heating, and high working temperature can be obtained under low working pressure.

2, high degree of automation, the use of advanced automatic temperature control mode, that is, through the set temperature feedback to the control system to achieve automatic adjustment of heat load. Using the perfect combination of fuzzy control and self-tuning PID control technology, the temperature control accuracy can reach ±1℃ ~ ±0.1℃, or even more. And can be connected with the computer, man-machine dialogue. The control system can provide the DCS system with the heater in operation, overtemperature, stop, temperature signal, interlock state and other signals, and can accept the automatic and stop operation command issued by the DCS. And add a reliable safety monitoring device. Such as:

① Conventional electrical protection, leakage protection, short circuit protection, etc.

② With a number of interlocking interfaces, at any time to effectively monitor the oil pump, flow, pressure.

(3) There is a set of overtemperature alarm system independent of normal temperature control. When the conventional temperature control is out of control due to various reasons, the system can not only alarm in time, but also turn off the electric heater unreset to ensure the safe operation of the system. And input the contact signal.

3, the equipment structure is reasonable, mature technology, complete supporting, short installation cycle, convenient operation and maintenance, safe and reliable, wide range of application.

4, the use of internal heat closed-circuit heating, high heat utilization rate, significant energy saving effect, and low operating costs, fast recovery investment.

● Main uses:

Used in petrochemical, oil materials, building materials industry, textile printing and dyeing, food, plastics, rubber, pharmaceutical and so on.
