Pipeline electric heater Introduction of two heating methods
Method 1: direct heating (internal heating)
Direct heating is achieved by Pipe heater The internal flange type tubular electric heating element is inserted upside down in the reactor jacket of the pipeline heater to heat the heat conducting oil, and the heat energy in the pipeline heater is transmitted to the chemical raw materials in the reactor inside the pipeline heater; or the tubular electric heating element in the pipeline heater is directly inserted into the reactor in the pipeline heater, or the electric heating pipe is evenly distributed around the wall of the pipe heater. This mode is called the internal heating type of the pipe heater. The internal heating type of the pipeline heater has the advantages of fast temperature rising and high efficiency.

Method 2: indirect heating (far infrared heating)
Indirect heating is the emergence in recent years, through the far-infrared electric heating equipment, the internal of the pipe heater Electric heater It covers the bottom of the reactor and the middle and lower parts of the pipeline heater for heating without direct contact. The far-infrared electric heating device of the pipeline heater has a large heating area of the internal system of the pipeline heater, which makes the temperature of the pipeline heater rise steadily and rapidly, the heat release of the pipeline heater is uniform, the temperature control of the pipeline heater is convenient, and the pipeline heating is convenient The heater can be controlled by upper, middle and lower sections. The temperature of the kettle wall in the pipeline heater kettle is easy to control. The pipeline heater has no side effect on the fuel in the kettle, and it will not cause carbonization of the material in the pipeline heater. The pipeline heater has no noise and pollution. The pipeline heater has the characteristics of long-lasting durability, and the energy-saving effect of the pipeline heater is very obvious.
The materials heated and dried in the far-infrared pipeline heater absorb the far-infrared radiation energy at the same time inside the pipe heater and the surface molecules of the pipe heater at a certain depth. The pipeline heater will absorb the energy and generate heat like the solar energy. When the material in the pipeline is heated, the heating of the pipe heater is uniform, thus avoiding the quantitative change of the pipeline heater due to different thermal expansion degrees, It can maintain the shape, physical and mechanical properties, fastness and color of the object to be heated. Pipeline heater is widely used in electronics, electrical appliances, textile, energy and other fields. Far infrared pipeline electric heater has the advantages of good radiation effect, energy saving, convenient and flexible use.
