Sponge iron oxygen to overcome the steel scrap oxygen, less surface area than the major drawback easily passivated, full contact with water; but found the general sponge iron powder easily, sometimes harden in practical applications, unstable oxygen cases, the study found that in general the best management sponge iron steel scraps to overcome these shortcomings, but because for steelmaking impurities generally only focus on its total iron and sulfur, phosphorus, etc., for the proportion to be the bigger the better, the smaller surface area better (larger surface area in the smelting process more easily oxidized), there is no requirement for physical strength, and the non-ferrous impurities, oxygen and water treatment requirements opposite. Because we use oxygen sponge with which the following main points: First, the active iron content, the better the activity of iron; second, the specific surface area; third, physical strength, the index is too small to easily pulverized; it is generally used sponge Water problems in more oxygen. The sponge iron oxygen water that is dedicated to "normal sponge iron oxygen scavenger" system using a special process and then by reducing secondary crushing, magnetic separation, screening, testing and other processes carefully made, so there will not harden, powder, sponge iron filter oxygen principle: The sponge has enormous surface area of ??the filter, when water containing dissolved oxygen by sponge iron, the oxygen in the water and sponge iron oxidation reaction occurs completely tired students to a certain extent. , they can drain through the backwash, the ability to restore to the initial oxygen sponge iron filter working environment: Dealing with water: 4-50t / h Backwash intensity: 16-21L / m2 Backwash interval: 24h Working temperature: 5-80 ℃ oxygen speed: 15-18m / h before treatment dissolved oxygen content: 6-8mg / L Working pressure: dissolved oxygen content after 0.15-0.5MPa process:. 0.03-0.05mg / L sponge iron filter Applications : all kinds of boilers, heat exchangers, heat pipes water, industrial cooling water and oil field water sponge filter characteristics: 1. help long life, non-toxic, do not pollute the environment, water oxygen content stabilize at 0.05mg / L or less, and in full compliance with national low-pressure boiler water quality standards (GB1576-2001) requirements. 2. normal operation without heating, low running costs, to overcome the thermal oxygen, vacuum oxygen required heating energy consumption drawback. 3. less ., generally oxygen scavenger consumption per ton of water 10g 4. backwash frequency is low, good regeneration sponge Present Situation and Prospects: In China, the production of sponge iron industry, mainly coal-based tunnel kiln tank type method, this process technology is relatively mature, relatively stable, treated sponge iron activated oxygen scavenger, spongy porous iron particles, the dissolved oxygen in water to provide an opportunity to react with the active iron to accelerate redox reaction, it dissolved oxygen chemical reaction with water as follows: Fe + H2O + 1 / 2O2 → Fe2 ++ 2OH- Fe2 ++ 2OH- + 1 / 2H2O + 1 / 4O2 → Fe (OH) 3 ↓ sponge application Range: can be used for a variety of boilers, heat pipes water, industrial cooling water, etc. need to remove dissolved oxygen place.
