Shell is welded of cylinder and stamping elliptical head. Small and middlesize low pressure deaerator has one couple of flanges connecting the top and bottom for assembly and repair purpose. High pressure deaerator hasmanhole for repair purpose.2.起膜器：由水室、汽室、起膜管、凝结水接管、补充水接管和一次进汽接管组成。
Film collector is composed by water tank, steam room, film collect pipe,condensed water pipe, feed water pipe and inlet steam pipe.3.凝结水、化学补水、经起膜管呈螺旋状按一定的角度喷出，形成水膜裙，在此通过一次蒸汽接管引进的蒸汽加热，及由二次蒸汽接管引进的蒸汽经液汽网、水篦子后的蒸汽充分加热，达到接近除氧器工作压力下的饱和温度（即低于饱和温度2-3℃）并进行粗除氧。
一般经此膜段可除去给水中含氧量的90-95%左右。
Condensed water, chemical feed water helically sprays out at a certain angle through film collector to build up a water film net where steam from inletsteam pipe will be heated, and the steam will fully heated with outlet steam flow through liquid & steam net and the grate to achieve the saturatedtemperature to roughly deoxidation. Generally it can deoxidize 90% to 95% oxygen content.4.淋水篦子：是由数层交错排列的角形钢制件组成，经起膜段粗除氧的给水及由疏水管引进的加热器等疏水在这里混合进行二次分配，呈均匀淋雨状落到装到其下的液汽网上。
Spray grate is composed by layers crossed angle steel. There are roughlydeoxidized feed water and drain water from heater draining pipe mixed and distributed again, and regular spray to lower liquid & steam net.5.液汽网：是由相互间隔的扁钢带及一个圆筒体，内装一定高度特制的不锈钢扁丝网组成，给水在这里与二次蒸汽充分接触，加热到饱和温度并进行深度除氧，以保证除氧水中含量：低压大汽式除氧器低于10μg/L，高压除氧器低于7μg/L。
Liquid and steam net is composed by separated flat steel tape and roundcylinder with certain height of stainless steel flat wire net inside. The feedwater meets outlet steam adequately, and heat to saturated temperature to deeply deoxidation to make sure the oxygen content of low pressuredeaerator lower than 10μg/L, and 7μg/L for high pressure deaerator.6.水箱：未凝结的蒸汽和由给水解析出来的氧等气体，经装在封头上的排汽管排出，除过氧的给水汇集到除氧头的下部容器即水箱内。
Water tank, uncondensed steam and oxygen separated from feed water shall be discharged from steam discharging pipe from the head, and thedeoxidized water will flow to the water tank.四、连接系统和附件: CONNECTING SYSTEM AND ACCESSORIES除氧器在安装工地与水箱的接口圈焊接，构成除氧设备，除氧器设备附件包括：Deaerator is welded in field with the water tank interface, and the equipment accessories are listed below.1.安全阀：装有水箱上，当设备内在压力超出允许值时，安全阀自动打开泄压，起安全保护作用。
