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 reacts Fe2O3 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, the working 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.
2, the main characteristics
Technical features: sponge iron deaerator adopts the techniques and working principle has the following features:
1) can be realized at room temperature, heating water without oxygen,
2) systems available water, don't need preparation time, also don't need oxygen tank,
3) oxygen stable and reliable, and the effect of oxygen content in water stability than 0.05 mg/L, accord with standard of low-pressure boiler water,
4) no special requirements, overcome the heat, high vacuum deaeration must install the inconvenience,
5) equipment can be low to decorate, simple production process, no high height requirement.
