防爆流体加热器

    空气加热器是主要对气体流进行加热的电加热设备。空气加热器的发热元件为不锈钢电加热管，加热器内腔设有多个折流板（导流板），引导气体流向，延长气体在内腔的滞留时间，从而使气体充分加热，使气体加热均匀，提高热交换效率。空气加热器的加热元件不锈钢加热管，是在无缝钢管内装入电热丝，空隙部分填满有良好导热性和绝缘性的氧化镁粉后缩管而成的。当电流通过高温电阻丝的时候，产生的热通过结晶氧化镁粉向加热管表面扩散，再传递到被加热空气中去，以达到加热的目的。

The air heater is an electric heating device which mainly heats the gas stream. The heating element of the air heater is a stainless steel electric heating tube, and the inside of the heater is provided with a plurality of baffles (baffles) to guide the gas flow and prolong the residence time of the gas in the cavity so that the gas is sufficiently heated so that the gas Heating evenly, improve heat exchange efficiency. Air heater heating element Stainless steel heating pipe, is installed in the seamless steel pipe heating wire, filled with a good part of the thermal conductivity and insulation of the magnesium oxide powder after the shrinkage made. When the current through the high temperature resistance wire, the heat generated by the crystallization of magnesium oxide powder to the surface of the heating tube, and then passed to the heated air to achieve the purpose of heating.
