电加热反应釜优缺点对比

时间:2017-10-23作者:舜甫科技 点击:
  电加热反应釜具有加热迅速、耐高温、耐腐蚀、卫生、无环境污染、无需锅炉自动加温、使用方便等特点。用电热棒加热夹套里面的导热油,使导热油温度升到所需要的温度,然后有测温控制仪控制电热帮使期断电恒温。是在吸收国内外先进技术的基础上研制成功的新型产品,广泛地应用于医药、化工、食品、天然调味品、食品添加剂、轻工等行业。
 
  由于部分电加热反应釜超温超压,所以要及时检查、修复自控系统;严格执行操作规程;根据操作法,按规定定量定时投料,严防误操作;增加传热面积或清除结垢,改善传热效果;及时修复搅拌器,提高搅拌效率;关总汽阀,断汽修理阀门。电加热反应釜的搅拌器已经摒弃了单一搅拌器发展到用双搅拌器或外加泵强制循环。
 
  反应釜采用电加热时,设备较轻便简单,温度较易调节,而且不用泵、炉子、烟囱等设施,开动也非常简单,危险性不高,成本费用较低,但操作费用较其它加热方法高,热效率在85%以下,因此适用于加热温度在400℃以下和电能价格较低的地方。当下电加热反应釜外表面一般焊蛇管,由于蛇管与釜壁有间隙,这就使热阻增加,传热效果降低。现在新应用的热管技术很好的克服了这些缺点,将是电加热反应釜发展趋势。
 
  The electric heating reactor has the characteristics of rapid heating, high temperature resistance, corrosion resistance, sanitation, no environmental pollution, no need of automatic heating of boiler and convenient use. The electric heating rod is used to heat the heat conducting oil in the jacket, so that the temperature of the heat conducting oil is raised to the required temperature, and then the temperature control device is used to control the electric heating force to make the power supply cut off and keep constant temperature. It is a new product developed on the basis of absorbing advanced technology at home and abroad. It is widely used in medicine, chemical industry, food, natural condiment, food additive, light industry and other industries.
 
  Automatic control system of electrical inspection, repair processing method of heating reactor temperature and pressure exceeding the implementation of strict rules, according to the operation method, take emergency pressure release, according to the provisions of the timing quantitative feeding, to prevent misoperation, increase the heat transfer area or remove scaling, improve the heat transfer effect of repairing the agitator, improve the mixing efficiency, off steam valve, cut-off valve repair. The agitator of the electric heating reactor has abandoned the single agitator and developed into a forced circulation with a double agitator or an external pump.
 
  The electric heating device is simple, portable, easy temperature regulation, without pump, stoves, chimneys and other facilities, use is also very simple, the risk is not high, the cost is low, but the operation cost compared to other methods of heating, thermal efficiency is below 85%, so it is suitable for the heating temperature can lower prices the place below 400 DEG C and electricity. At present, the outer surface of the electric heating reactor is generally welded with a snake tube. Because of the gap between the snake tube and the kettle wall, the thermal resistance is increased, and the heat transfer effect is reduced. Now the new application of heat pipe technology is a good way to overcome these shortcomings, will be the development trend of electric heating reactor.
