Application of Electric Heating Thermal Oil Furnace in Meltblown Nonwoven Machine (Hot Press, Nonwoven Roller)

Nonwoven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is a new generation of environmentally friendly material with characteristics such as moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxic and non-irritating, rich colors, low cost, and recyclability. For example, it is mostly made from polypropylene (PP) pellets as raw material, produced through a continuous one-step process of high-temperature melting, spinning, web laying, hot pressing, and winding. It is called cloth because it has the appearance and certain properties of cloth.

Nonwoven fabric is not woven or knitted from yarns, but fibers are directly bonded together through physical methods. In existing technology, it is mainly produced by spinning through a spinneret and then hot pressing to form the nonwoven fabric. The main function of the electric heating thermal oil furnace produced by our company is to heat the thermal oil.

The electric heating thermal oil furnace, an organic heat carrier furnace, is a new type of safe, energy-saving, high-efficiency, low-pressure, and high-temperature heat-providing special explosion-proof industrial furnace developed based on advanced foreign technology. This furnace uses electricity as the heat source, i.e., tubular electric heating elements immersed in thermal oil generate heat when electrified. With thermal oil as the heat carrier, it is forced to circulate by a hot oil circulation pump, transferring heat to one or several heat-using equipment. After the heat is unloaded by the heat-using equipment, the thermal oil returns through the circulation pump to the electric heating thermal oil furnace to absorb heat again and transfer it to the heat-using equipment, repeating the cycle to achieve continuous heat transfer. This ensures that the heat-using equipment obtains a continuous and stable high-temperature energy source, meeting the process requirements for medium heating. The electric heating thermal oil furnace can use a digital temperature controller for temperature control, with functions such as over-temperature alarm, low oil level alarm, and over-pressure alarm. It also has anti-dry burning and explosion-proof safety measures. The explosion-proof electric heating thermal oil furnace has explosion-proof grades such as exdiibt4, exdiibt6, exdiict6, etc.

The electric heating thermal oil furnace system consists of an explosion-proof electric heater, an organic heat carrier furnace, a heat exchanger (if any), an on-site explosion-proof operation box, a hot oil pump, an expansion tank, etc., assembled into a skid. Users only need to connect the power supply, the inlet and outlet pipelines of the medium, and some electrical interfaces to use it.
