Nonwoven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is made 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, polypropylene (PP) pellets are often used as raw materials, which are produced by a continuous one-step process of high-temperature melting, spinning, web laying, hot pressing, and winding. It is called cloth because of its appearance and certain properties.
Nonwoven fabric is not made by interweaving or knitting yarns one by one, but by directly bonding fibers together through physical methods. In the existing technology, it is mainly produced by spinning through a spinneret and then hot pressing to finally 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 (organic heat carrier furnace) is a new type of safe, energy-efficient, low-pressure, high-temperature special explosion-proof industrial furnace developed on the basis of absorbing advanced foreign technology. This furnace uses electric energy as the heat source, that is, the tubular electric heating elements immersed in the thermal oil generate heat when powered on, and uses thermal oil as the heat carrier. Through forced circulation by a hot oil circulation pump, the heat is transferred to one or several heat-using equipment. After the thermal oil is unloaded by the heat-using equipment, it returns to the electric heating thermal oil furnace through the circulation pump to absorb heat again and transfer it to the heat-using equipment, repeating the cycle to achieve continuous heat transfer. It ensures that the heat-using equipment can obtain a continuous and stable high-temperature energy source, meeting the process requirements of 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 heating and explosion-proof safety measures. The explosion-proof grade of the explosion-proof electric heating thermal oil furnace is 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), a field explosion-proof operation box, a hot oil pump, an expansion tank, etc., combined 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.
