旋膜式除氧器安装、使用说明书Rotary film type deaerator installation, operation instruction一、旋膜除氧器的设计特征one, rotary membrane deaerator design features旋膜除氧器，是一种新型热力除氧器，可用于定压、滑压、负压等方式运行，适应于各类电站锅炉、工业锅炉给水及热电厂补给水或热用户用水的除氧。
Rotary membrane deaerator, is a new type of thermal deaerator, can be used for constant pressure, sliding pressure and negative pressure means such as operation, suitable for all kinds of power station boiler, industry boiler feed water and thermal power plant supplies water or hot water users of oxygen.旋膜除氧器的设计特征是：Rotary membrane deaerator design features are:利用气体在水中的溶解特性，通过加热蒸汽，将进入除氧器的补给水、凝结水（包括各种疏水）加热到与除氧器内部压力相对应的饱和温度。
根据亨利定律和道尔顿定律，溶解水中的氧和二氧化碳等非冷凝气体自水中析出，由顶部排气管排入大气，使水中的含氧量达到规定的标准，合格的除氧水贮存在除氧器下部的水箱中，随时准备锅炉给水的需要。
Using gas in water dissolving characteristic, through the heating steam, will enter the deaerator supply water, condensate (including all kinds of hydrophobic) heating to the deaerator internal pressure corresponding saturation temperature.According to Henry's law and Dalton law, the dissolution is the water of oxygen and carbondioxide and noncondensable gas from the water precipitation, the top exhaust pipe into the atmosphere, make the water of oxygen content meet the prescribed standard, qualified oxygen water stored in the lower part of deaerator water tank, ready to boiler feed water needs.旋膜除氧器，由于具备上述技术特性，尤为适用热电厂，热电厂的补给水量大（补水率最大要求100％），补给水温低（最低要求－15℃），含氧量高（约10000ug/L）。
一般除氧器在这种条件下，难于将补给水中溶解氧排除到达到规定的标准。
因此，往往将热力系统设计，为大气式及压力式除氧器两级串联运行方式，即补给水先送入大气式除氧器，经一次除氧后再送入压力式除氧器进行二次除氧，既增加了设备与运行操作，又增加了厂房建筑面积。
Rotary membrane deaerator, because have the above technical characteristics, particularly for thermal power plant, thermal power plant supply water (water rate maximum demand 100%), supply water temperature low (minimum requirements - 15 ℃), oxygen content high (about 10000 ug/L). General deaerator in this condition, the difficult to will supply the water dissolved oxygen (do) ruled out to meet the prescribed standard.Therefore, often will thermal system design, for atmospheric type and pressure type deaerator two stage series operation mode, namely make-up water first into the atmospheric type deaerator, via a oxygen before into pressure type deaerator for secondary oxygen, which increased the equipment and operation, and increase the area of factory building.如果，热电厂采用旋膜除氧器，则可根据需要选用一台压力式或大气式除氧器一次将补给水中的溶解氧排除至规定的标准。
这样，可以节省一台除氧器及相应的厂房面积，运行管理也方便。
因此，旋膜除氧器，是电力行业推广的新产品，在国内外处于领先水平。
If, thermal power plant using spiral membrane deaerator, can according to need to choose a pressure type or atmospheric type deaerator a will supply the water dissolved oxygen (do) to eliminate the provisions of the standard.In this way, can save a deaerator and corresponding workshop area, operation management and convenient.Therefore, rotary membrane deaerator, is the electric power industry promotion of new products at home and abroad, a leading level.二、基本结构和工作原理Second, the basic structure and working principle旋膜除氧设备，由旋膜除氧器、除氧器水箱以及附件组成，按水流方向，由上而下分为排气区段，起膜器组，空间区段，水蓖层、填料层、蒸汽分配时机及除氧水箱等组成。
Rotary membrane oxygen equipment, by rotary membrane deaerator, deaerator water tank and accessories composition, according to the flow direction, by go up and divided into exhaust section, the film machine group, the space section, water layer, labyrinth packing layer, steam distribution time and oxygen tank, etc.主凝结水、补给水及其它软化水通过管道进入起膜器贮水室，经起膜器上若干个切向螺旋形排列的小孔由起膜管外壁，以高速的射流而出，然后贴管内壁形成湍流旋转水膜，旋转而下，最后由离心作用在起膜管下端出口形成水膜裙，进入空间区段。
在这样的工况下，起膜管是中空的，加热蒸汽可以通畅的由其中通过，并受水的吸卷，与水充分搅合，进行热质交换，冷凝成水，能量消失后变成水滴，以自由落体下降，是为一级除氧；Main condensate, make-up water and other softening water through the pipe into the membrane device storage water chamber, by the membrane device on the several tangential spiral array holes by the membrane tube outer wall, with high-speed jet out, and then stick tube wall form turbulence rotating water film, rotate, finally by centrifugal action in the film pipe bottom export formation water film skirt, into space section.In such conditions, the film pipe is hollow, heating steam can unobstructed by it through, and by water suction roll, and the water fully JiaoGe, carries on the heat and mass transfer, condensed into water, energy disappears into water droplets to free fall down, it is for level 1 oxygen;除氧水进入蓖条组及填料层进入深度除氧后，汇聚于水箱，送入锅炉与此同时溶解于水中的氧和其它不凝结气体不断的从水中逸出，上升进入排气区间，水膜裙交叉空间可能滞留的气体，由连通管排至排气区，再经气水分离器进入排气管排入大气。
Oxygen water into article labyrinth packing layer and group into depth oxygen, gathering in water tank, into the boiler meanwhile dissolved in the water of oxygen and other not condensate gas unceasingly from the water escape and rise into the exhaust interval, water film skirt cross space may be stranded gas, by communicating pipe line to exhaust area, then qi water separator into the exhaust pipe is vented to atmosphere.三、设备的型号及技术规范Three, equipment model and technical specifications旋膜除氧器，分为压力式、大气式两种类型。
