Introduction;
Non-woven Fabric Heater Model
Stock supply of non-woven machine compressed air heater is an electric heating device mainly for heating gas flow. The inner cavity of the compressed air heater is equipped with multiple baffles (guide plates) to guide the gas flow direction, prolong the residence time of the gas in the cavity, so that the gas is fully heated, the gas heating is uniform, and the heat exchange efficiency is improved.
Detailed explanation;
Non-woven Fabric Heater Model
It is a new type of environmentally friendly heat energy conversion equipment. It uses electricity as energy and compressed air as the medium. The flowing medium is input from the pump body pressure at low temperature, and absorbs heat energy during the flow process to reach the process required temperature at the equipment outlet. Through the temperature detection device at the equipment outlet and the regulation of the electric heater power, the fluid medium temperature can be ensured to meet the process requirements. With the help of equipment sensors and protection devices, once the medium temperature is too high, the equipment will intelligently stop heating; once the heating element is overheated, the heating will also stop to avoid overheating damage to the heating element.
Working principle:
High-temperature resistance wires are evenly distributed inside a high-temperature resistant stainless steel seamless tube, and the gaps are densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced, with high thermal efficiency, but also uniform heating. When current passes through the high-temperature resistance wire, the generated heat diffuses through the crystalline magnesium oxide powder to the surface of the metal tube, and then transfers to the heated part or air gas, achieving the purpose of heating.
Heater is mainly used to heat the required gas flow from the initial temperature to the required gas temperature, up to 800°C. It has been widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry, and higher education institutions. It is especially suitable for automatic temperature control and high-flow high-temperature system and accessory tests. The compressed air heater has a wide range of applications: it can heat any gas, and the generated hot gas is dry, non-conductive, non-combustible, non-explosive, non-corrosive, reliable, and the heated space heats up quickly (controllable).
