真空除氧器操作说明一篇中英文的介绍与除氧器设备附件

真空除氧器操作说明:

       1、气体在水中的溶解度与气体在水面温度和气体类型上的分压有关。根据亨利定律,当水温达到相应压力下的饱和温度时,水开始沸腾,其在水中的溶解度等于零。此时不再溶解气体,水面上的蒸汽压力等于外压,气体的分压等于零。水的沸点与水的压力成正比。例如,在正常温度下,水在100度沸腾,当压力降低时,水的沸点降低。真空除氧的原理使表面上的水的压力抽成真空,沸腾的普通开水达到脱氧的目的。

     

       真空除氧器除氧头、除氧水箱、抽真空装置、真空引水泵等均可安装,适用于蒸汽锅炉给水系统、热水锅炉给水除氧器除水等气体。它具有以下优点:

       (1)除氧装置不仅能除去水中的氧气,也可除去二氧化碳和其他气体;

       (2)当氧气消耗的蒸汽锅炉,全部使用;

       (3)氧热水供暖锅炉房没有额外的蒸汽时,水的供应;

       (4)运行稳定,真空度高,操作方便;

       (5)从正常运行的时间开始,除氧效果不变,当负荷变化在0-120 %的范围;

       (6)增加水中没有氧盐和其他杂质的量;

       (7)低的安装,方便的小型锅炉单层布置,节省投资;

       (8)SZY的装配设备,一体化的整体设备,小占地面积大,安装方便,设备到位后,水管连接,接通电源即可投入运行。

Vacuum deaerator operation instructions

        1.the gas solubility in water is related to the partial pressure of the gas on the water surface temperature and the type of gas. According to Henry's law, when the water temperature reaches the saturation temperature at the corresponding pressure, water begins to boil, and its solubility in water is equal to zero. No longer dissolved gas, at this time the steam pressure on the water surface is equal to the external pressure, and the partial pressure of the gas is equal to zero. The boiling point of water is proportional to the pressure at which water is located. For example, at normal temperatures, water boils at 100 degrees, and when the pressure is lowered, the boiling point of water is lowered. The principle of vacuum deaeration makes the pressure on the surface of the water pumped into a vacuum, boiling the ordinary boiling water to achieve the purpose of deoxidization. 

        The deaerator deaerator head, deaerator water tank, vacuum pumping device and vacuum diversion pump etc., can low installation, suitable for steam boiler feedwater system, hot water heating boiler feed water deaerator to remove water and other gases. It has the following advantages: 

        (1) deoxidization device not only can remove the oxygen in the water, can also remove carbon dioxide and other gases; 

        (2) when the oxygen consumption of steam boiler, all use;

        (3) oxygen in hot water heating boiler room without extra steam when the supply of water; 

        (4) stable operation, high vacuum degree, convenient operation; 

        (5) from the start of the normal operation of the time, the deoxidization effect unchanged when the load changes in the range of 0-120%; 

        (6) increase the amount of salt and other impurities by no oxygen in water; 

        (7) low installation, convenient for small type boiler single-layer arrangement, save investment; 

        (8) SZY for the integration of assembly equipment, overall equipment, small occupied area, convenient installation, equipment in place after water pipe connected, connected to the power supply can be put into operation.
