海绵铁除氧剂∕ 海绵铁除氧剂滤料∕ 除氧海绵铁

     海绵铁具有较好的还原活性和高比表面积特点，作为水除氧剂的海绵粒度为2-5mm，孔隙率极高，比表面积大，活性高，极易与水中的氧发生反应生成Fe3O3,从而达到除氧目的，反应产物为不易溶于水的絮状沉淀，被拦截下来，用一定强度的反洗水可以冲洗干净。
       1、工作原理
        常温过滤式除氧属化学除氧，它采用专门生产的活性海绵铁(直接还原铁)来去除水中溶解氧，海绵铁主要成分是铁，其疏松多孔的内部结构，提供的比表面积是普通铁屑的5-10万倍，可使水中的氧与铁发生迅速彻底的氧化反应，使溶解氧稳定在0.05mg/L以下，其反应式为：
        2Fe2+ + 2H2O + O2→2Fe(OH)2 4Fe(OH)2+ 2H2O +O2→4Fe(OH)3
        反应产物Fe(OH)2、Fe(OH)3为不易溶于水的絮状沉淀，当随着水流经其余的海绵铁颗粒时被拦截下来，只要用一定强度的反洗水流就可以冲洗干净(大约5分钟)。
        海绵铁的消耗量很低，根据处理水量与水质的不同，一般3 - 6个月补充一次即可。
        (经过除氧后的中增加了少量的铁离子,一般为0.2 - 0.5mg/L，对于热水锅炉来说仍符合国家规定的水质标准，但对于蒸汽锅炉或对给水Fe2+有严格要求的给水除氧来说，可以加装除铁装置，去除水中的Fe2+。)
        作为水除氧剂的海绵铁是利用粒度在-200目以下的Fe3O4 粉末粘结在一起，粒度为2-5mm左右。因其还原过程发生置换反应，形成一定数量的空隙，还有粉末微粒粘结时的空隙，使得除氧剂孔隙极高，比表面积大，又因其为原生矿直接还原所得，相对纯净，所以活性极高，极与水中的氧发生反应生成Fe3O4，从而达到除氧目的。同时利用率也得到提高到90%以上。
        而且由于含有一定量的杂质，使其在除氧过程中颗粒之间只能是弱键连接，基本不锈死成团。该产品经多家单位使用后，效果十分理想，出水含氧量降到0.05mg/L以下，处理每立方米水仅消耗25g左右，真正做到了高质量、低成本运行。
因不经软化的水易使除氧剂表面发生钝化，使其氧化减慢，而影响除氧效果，故应先软化再除氧。使用一段时间后，应进行反洗

Sponge iron has good reduction activity and high specific features, as the water in sponge granularity for 2-5mm, porosity, high spicific surface extremely easily, high activity, with the oxygen react Fe3O3 formation, thus achieved the purpose of oxygen, reaction products for easy soluble in water, floc was with a certain intensity, the wash water rinse clean can.
1 and work principle
Normal oxygen removal filter brand-newly type of chemical oxygen, it adopts special production activity sponge iron (direct return) to remove water oxygen, sponge iron main component is iron, its loose porous, the internal structure of the surface is provided general iron 5-10 million times, can make the oxygen and iron happen quickly complete oxidation reaction, make the dissolved oxygen stable at 0.05 mg/L below, its type:
2Fe2 + + 2H2O + O2-2Fe (OH) 2 4Fe (OH) 2 + 2H2O + O2-4Fe (OH) 3
Reaction products Fe (OH) 2, Fe (OH) 3 for not soluble in water, as floc flow through the rest of the sponge iron granules were intercepted by a certain intensity and if the washing water can be rinsed clean (about 5 minutes).
The consumption of sponge iron is very low, according to the different water quality and water treatment, 3-6 months added again.
(after the oxygen in small amounts of iron ions increased, general 0.2-0.5 mg/L for hot water boiler, it is still that accords with national regulation of water quality standards, but to steam boiler of Fe2 + water or have strict water, can add iron removal device, the Fe2 +).
As the water in sponge iron is using particle in Fe3O4 below 200 - powder together, particle size for about 2-5mm. Because of its reduction process replacement, a certain amount of space, and powder particles, make the space when bonding agent of high oxygen pore, high spicific surface, and because of its original mineral for direct reduction of income, relatively high purity, so activity, and the oxygen react Fe3O4 formation, thus achieved the purpose of oxygen. While the efficiency improvement to 90%.
And because the impurities, containing in the process of oxygen between particles are only key links, basic doesn't rust. This product by several units, the effect is very ideal, after water to 0.05 mg/normoxia under L, 25g consumption per cubic meter of water only around it, high quality and low cost.
Because of the water to soften agent of oxygen, make its surface passivation happen, but slow oxidation affect oxygen effect, so be softened to oxygen. After a period of using, should carry out the washing
