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, polypropylene (PP material) pellets are often used as raw materials, which are produced by high-temperature melting, spinning, web laying, hot pressing and winding in a continuous one-step process. It is called cloth because it has the appearance and some properties of cloth.
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 formed by spinning through a spinneret and then hot pressing to finally form 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-saving, high-efficiency, low-pressure special explosion-proof industrial furnace that can provide high-temperature heat energy, developed on the basis of absorbing advanced foreign technology. This furnace uses electric energy as the heat source, that is, the tubular electric heating element immersed in the thermal oil generates heat when electrified, and uses the thermal oil as the heat carrier. Through the forced circulation of the hot oil circulation pump, the heat is transferred to one or several heat-using equipment. After being unloaded by the heat-using equipment, the thermal oil returns to the electric heating thermal oil furnace through the circulation pump to absorb heat again and transfer it to the heat-using equipment, and so on, realizing continuous heat transfer. Ensure that the heat-using equipment can obtain continuous and stable high-temperature energy. Meet the process requirements of medium heating. The electric heating thermal oil furnace can use a digital temperature controller for temperature control, with over-temperature alarm, low oil level alarm, and over-pressure alarm functions. It also has anti-dry burning 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), an on-site 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.
