Sponge iron deaerator Rationale: I. Overview: remove oxygen dissolved in the water, to prevent boiler corrosion or other water equipment to ensure its safe and economic operation has a vital significance. However, over the years it has been the traditional method of oxygen (thermal oxygen, vacuum oxygen, redox resin oxygen desorption of oxygen, oxygen steel scrap, etc.), due to harsh external conditions, reach Ideal effect of oxygen or can not operate economically distressed. It overcomes the shortcomings of traditional methods of oxygen, dissolved oxygen content in the water 0.05mg / 1 or less, and the results have become oxygen equipment replacements. Second, the principle to let the water containing oxygen through a special sponge iron filter (the filter has a huge surface area, copper scrap is 5-10 times, so that the water of oxygen and iron oxidation reaction occurs completely, its chemical reaction is: 2Fe + 2H20 + O2 → 2Fe (OH) 2 2Fe (OH) 2 + H20 + 1 / 2O2 → 2Fe (OH) 3 ↓ reaction product was soft floc, a high active oxygen scavenger sponge stored at the surface, and was trapped, it can easily be washed away backwash water, excluded.
