加热器

QJY型油加热器
QJY Oil Heater

●主要用途
  本产品用于饱和蒸汽加热燃油和滑油的一种管壳式热交换器。
●结构说明
  本加热器是常用的管壳式换热设备,由端盖、壳体、管组和附件组成。端盖是带有油进、出口接管的封头。壳体是无缝钢管(也可由钢板卷焊成型),壳体上焊有蒸汽进口接管、凝水出口接管、安全阀座、放泄口等附加零件。管组由管板、折流板、“U”型加热管等组成。壳体外表面包扎绝热材料,可减少热量散失。
●原理
  油从端盖进口进入加热器,在“U”型管内作迂回往复流动,通过管壁吸收蒸汽的潜热,再从端盖上的油出口流出。通过调节蒸汽的流量,使出口油温达到设定要求。蒸汽从壳体上端蒸汽进口进入,通过折流板在壳腔流动,再从凝水出口排出。


●The main purpose
   The product is a shell-and-tube heat exchanger used for heating fuel and lubricating-oil with saturated steam.
● Introduction of the structure
   The heater is a kind of used shell- and-tube heat exchanger which consists of head cover, Shell, nest of tubes and accessories. The head cover is a seal head with oil inlet and outlet adapters attached. The shell is made of seamless steel pipe (also can be formed by steel plate roll welding), steam inlet adapter, condensing water outlet adapter, safety valve base, discharge and etc. are welded on the shell. The nest of tubes consists of tube sheet, baffle, U-heating tube and so on. The insulation materials are wrapped in appearance of the shell to reduce the heat loss.
●Principle
    The oil entering the heater from inlet of the head cover makes advance and return movement in U-tube to absorb latent heat of steam through tube wall, and then come out from oil outlet of the head cover. Through adjust the steam flow capacity so as to reach design requirements of the outlet oil temperature. The steam entering from the steam inlet of upper shell flows in the shell cavity through the baffle, again discharges from the condensing water outlet.
