Electric Mineral Insulated Heaters For Heat Conduction Oil

500KW Electric Mineral Insulated Heater for Heat Conduction Oil is a heating device of new type, safety, high efficiency and energy saving and low pressure (atmospheric pressure or lower pressure). It can provide high temperature heat energy for special industrial furnace. Taking heat conduction oil as heat carrier, the heater transfers the energy by heating pump to circulate heat carrier to transfer the heat to heat-use equipment.

I. Technical parameters of 500KW heat-conducting oil electric heater:

1. Heating medium: heat conduction oil;

2. Heating temperature: 0-350℃;

3. Work output: 500KW;

 

Two, 500KW heat conduction oil electric heater function overview:

500KW heat conduction oil electric heater is a heating device of new type, safety, high efficiency and energy saving and low pressure (atmospheric pressure or lower pressure). It can provide high temperature heat energy for special industrial furnace. Taking heat conduction oil as heat carrier, the heater transfers the energy by heating pump to circulate heat carrier to transfer the heat to heat-use equipment.

 

Electric heat conduction oil heating system consists of explosion-proof electric heater, organic heat carrier furnace, heat exchanger (if any), on-site explosion-proof operation box, hot oil pump, expansion tank, etc., which is combined into a skid block. Users only need to access the inlet and outlet pipeline, power supply and some electrical interfaces for use.

 

Three, 500KW heat conduction oil electric heater working principle:

 

heat is generated and transported by the electric heating element immersed into the heat conduction oil. Heat conduction oil, as medium circulated by circulating pump, is forced to liquid circulation and transfers heat to one or multiple heat using equipment. After unloading at the heating equipment, the heat oil returns to the electric heater through the circulating pump for absorbing heat then go back to heat use equipment. Around this circulation, the continuous transmission of heat is realized. The heated object temperature is increased while heating process requirement is reached.

 

Four, 500KW heat conduction oil electric heater application scope:

 

Petroleum and chemical industry: polymerization, condensation, distillation, melting, dehydration, forced insulation.

 

Oil industry: fatty acid distillation, oil decomposition, concentration, esterification, vacuum deodorization and other reaction kettle temperature control, reactor heating.

 

Synthetic fiber industry: polymerization, melting, spinning, extension, drying.

 

Textile printing and dyeing work: heat setting roller heating, drying room heating, heat capacity dyeing.

 

Nonwovens industry: nonwoven fabrics.

 

Feed industry: drying.

 

Plastic and rubber industry: hot pressing, rolling, extrusion, vulcanization molding.

 

Paper industry: dry, corrugated paper processing.

 

Fifth, structure and working principle

1. Structure

The electric heater structure consists of nine parts. (See Figure 1)

2. Working Principle

The cold medium enters the diversion chamber through the oil inlet, so that the medium flows into the mixing chamber along the periphery of the heating element, and the mixed medium flows out from the oil outlet at a uniform temperature. The mixing chamber is equipped with a temperature measuring sensor, and the temperature signal is collected and transmitted to the electronic control system. The temperature control instrument controls the primary circuit to realize automatic control of the oil temperature. When the oil products or electric heating element of the heater is overheated, the protection device automatically cuts off the power supply and the control cabinet emits an audible and visual alarm signal.
