1、真空除氧器操作说明书中英文真空除氧器Vacuum Deaerator说明书Instruction江苏津宜水工业装备有限公司Jiangsu Jinyi Water Industry Equipment Co.,Ltd.、 用途天然水中溶有多种气体，在锅炉水给水中，氧对锅炉腐蚀的危害最大.为此国家标准 GB1576W5低压锅炉水质标准”中规定2吨/时以上锅炉必须除氧.真空除氧器的出水含氧量能满足标准的要求.真空除氧器还能够用于石油钻井回注水的除氧及水处理脱硫工艺 中氢离子交换器后除二氧化碳等多种场合.Application:There are various gases dissolved in
2、nature water; the oxygen contained in the boiler feed water may cause maximum corrosion to the boiler. So the national standard GB1576-85 low-pressure boiler water quality standard clearly states that all the boilers of 2 t/h or higher are required to have their feed water deaerated. The oxygen leve
3、l in the treated water from the vacuum deaerator can meet the standard and requirement. The vacuum deaerators may also be used for deaeration of the return water in oil drilling industry and for CO2 removal after the hydrogen ion exchange in the desulfurization process of water treatment;二、原理真空除氧的原理
4、是基于亨利定律，即在封闭容器中，气体在水中的溶解度与该气体在水面上的分压力成正比.水在沸腾时，水面上蒸汽的分压力增加，溶解于水中的气体分压力随之减小，当水面上充满了水蒸气时，水不再具有溶解气体的能力，水中所溶解的气体就析出 从水的饱和温度特性可知，在真空状态下低温水也能沸腾.真空除氧就是利用这一特性达到除去气体（包括氧气）的目的.Working principle:The working principle of the vacuum deaeration is based on the Henry theory, that is, in a closed container, the sol
5、ubility of gases in the water is in proportion to the partial pressure of the gas on the water surface; when the water is boiling, the partial pressure of the steam on the water surface will increase, while the partial pressure of the dissolved gas will decrease accordingly; when the water surface i
6、s covered full with steam, the water will no longer have the capacity to dissolve the gas and then the dissolved gas in the water will be separated out. We can see from the saturated temperature characteristics of the water that low-temperature water can also boil under vacuum condition, which is ut
7、ilized by the vacuum deaerator to remove the gases including oxygen;三、特点1、运转工况稳定，真空度高，使用场合广.2、不消耗蒸汽，锅炉出力可全部利用.3、低温的除氧水可经过换热器回收低品位的废热后再作为锅炉给 水，从而收到节能效果.4、 适应性强，从负荷0-120%范围内变化时，除氧效果不受影响.5、 本除氧器除高位安装外，接上引水泵机组后还能够低位安装，便 于单层布置的小锅炉房用，节省投资，管理操作维修方便.Characteristics:1, Stable operating conditions, high level
8、 of vacuum and widespreadapplications;2, No consumption of steam and all outputs from the boiler may befully utilized.3, The low-temperature deaerated water may be recycled as feed water to the boiler after its low-grade waste heat is recovered by the heat exchanger to save the energy;4, High adapta
9、bility, the changes of the load within 0-120% will haveno impact on the deaeration efficiency;5, In addition to overhead installation, the deaerator may also be installed at low place after connection with the water pump, whichis suitable for small boiler room with only single floor featuring low co
10、st and easy and convenient management, operation and maintenance;四、技术规格真空除氧器主要由除氧器(脱气塔与除氧水箱)，水喷射真 空泵机组、引水泵机组等三部分设备组成，下述为除氧器技术规 格，其它设备可备阅其样本。Technical specifications:The vacuum deaerator mainly consists of deaerator (degas tower and deaerated water tank), water jet pump unit and priming pump unit. Th
11、e technical specification for the deaerator is described as following, the technical specifications for the other two parts may refer to corresponding instructions;五、设备与附件Equipments and accessories1、脱气塔脱气塔内装有铜制雾化喷头，每只喷头处理水量恒定，从而 得到最佳的喷雾效果。塔内装有填料层、传质快、亲水性能好。 雾化的结果大大增加了水的脱气面积，当雾化的水滴继续流经无 规则堆放的填料层时，进一步
12、加强了脱气效果。因此，虽然水在 脱气塔内停留的时间很短，然而除氧效果很好。Degassing tower:The degassing tower is provided with copper atomizing nozzles inside with stable water flow from each nozzle to achieve the best atomizing efficiency. The packing inside the tower features fast mass transfer and good hydrophilic performance. The a
13、tomization will result in the great increase of the degassing area of the water; and the degassing efficiency is further strengthened when the atomized water droplets flow through the packing layers stacked in disorder. As the result, despite the short-time retention of the water in the degassing to
14、wer, the deaeration efficiency is satisfactory;2、除氧水箱除氧器运行时，水箱内处于负压。因此在高位安装时，水箱 出口处与锅炉给水泵进口之间的净距离不得小于11米。在低位安 装时(水箱出水口与锅炉给水泵在同一高度)，水箱出水口要接 上引水泵机组，使负压水升压后进入锅炉给水泵，水箱上装有人 孔，便于维修保养时使用。Deaerated water tank:The water tank is in negative pressure inside when the dearator is running, so when the deaerator i
15、s to be installed at high position, the net distance between the outlet of the water tank and the inlet of the water feed pump of boiler shall be no less than 11 meters. When the deaerator is to be installed at low place (the outlet of water tank and the water feed pump of the boiler are at the same
16、 height), the outlet of the water tank shall be connected to the priming pump unit to increase the water pressure before flowing to the feed water pump of the boiler. The manholes furnished on the water tank are to be used during the maintenance;3、水喷射真空泵机组由水喷射真空泵、循环水箱、离心泵组成。离心泵将循环水经 过喷嘴造成高速水流而产生真空。本水喷射真空除氧装置可利用 软化兼作循环水，温度不会升高，因而可得到较高的真空度，提 高除氧效果。方法是利用原有的软化水水箱兼作循环水箱，节约 设备及占地面
