Sponge iron prices nationwide】 【boiler corrosion due to having a large specific surface area of ??sponge iron, surface energy is high, there is a strong electrochemical enrichment, strong reduction, physical adsorption and flocculation other superior physical and chemical properties, and therefore boiler water oxygen, phosphorus wastewater, organic wastewater, wastewater treatment electroplating wastewater and nitrates in certain applications and research. But all the reports, the sponge material for water treatment are mostly industrial sponge, due to the production of different purposes, the main consideration of industrial sponge rate of increase of the metal sponge, sponge lower impurity content, etc., while the associated with water treatment reduced iron grains degree of crystallinity, has sufficient surface area and strength, etc. are not considered. Therefore, the surface energy of industrial sponge generally not very high, and easy powder, pollutant removal efficiency is low. Report dwell sponge iron oxygen scavenger, oxygen scavenger sponge iron factory, sophisticated production equipment Product description deoxidants sponge filter (also called oxygen scavenger) using high-quality ore, the use of redox reaction principle, through the filter In addition to amylin way to exclude, for pipes, boiler circulating water dissolved oxygen corrosion treated water dissolved oxygen content can reach 0.05 mg / L or less, the oxygen scavenger with a backwash frequency is low, high compressive strength, not powder, no structural plate, large surface area. High activity, regeneration and good. The activated oxygen scavenger after sponge, spongy porous iron particles, dissolved oxygen in water to provide a reaction with the active iron opportunity to accelerate the oxidation-reduction reaction, it is dissolved with water chemical reaction is as follows: Fe + H2O +1 / 2O2 → Fe2 + +2 OH-Fe2 + +2 OH-+1 / 2H2O +1 / 4O2 → Fe (OH) 3 ↓ Applications: can be used for a variety of boilers, heat pipes water, industrial cooling water need to remove dissolved oxygen and other places. Sponge filter characteristics: high quality sponge iron ore, the use of redox reaction principle, in addition to sediment through filtration by way of exclusion, sponge iron oxygen scavenger, spongy porous iron tablets, dissolved oxygen in water provides a active iron reaction opportunity to accelerate the oxidation-reduction reaction, it is dissolved with water chemical reaction is as follows: Fe + H2O +1 / 2O2 → Fe2 + +2 OH-Fe2 + +2 OH-+1 / 2H2O +1 / 4O2 → Fe (OH) 3 ↓ Applications: can be used for a variety of boilers, heat pipes water, industrial cooling water. As water oxygen scavenger sponge filter particle size 2-5mm, high porosity, large surface area, high activity easily with water and oxygen react to form Fe3O3, to achieve the purpose of oxygen, the reaction product is not soluble flocculent precipitate in water, the main component is iron sponge, its porous internal structure, providing a specific surface area of ??5-10 times the ordinary iron, oxygen water can quickly and thoroughly and iron oxidation reaction, dissolved oxygen stable at 0.05mg / L or less, does not dissolve in water, soft floc, when accumulated to a certain extent it can drain through the backwash, the oxygen sponge to return to the initial capacity. Oxygen effect is stable and reliable, the dissolved oxygen content of stability ≤ 0.05mg / L, low-pressure boiler water quality standards in line sponge Features: The new sponge filter deaerator launched in the country for several years, sponge iron oxygen scavenger early design The device structure the reaction is: 2Fe2 + + 2H2O + O2 → 2Fe (OH) 2 4Fe (OH) 2 + 2H2O + O2 → 4Fe (OH) 3 the reaction product of Fe (OH) 2, Fe (OH) 3 is not soluble flocculent precipitate in water, when water flows through the rest of the sponge iron with particles to be blocked off, as long as a certain intensity of the backwash water can rinse (approximately 5 minutes). Sponge iron consumption is very low, according to the quantity and quality of the different treatment, usually 3 - 6 months added once. With a certain intensity of backwash water can rinse Hardness 5 - 7, the uniformity coefficient k80 ≤ 1.8, porosity of 30-50%, ash content <0.5 sponge filter for the first time into the deaerator, you must first go through backwashing to remove the sponge filter surface residues of floating ash impurities, such as water no obvious turbidity, the change is positive backwash wash, washing five minutes after the normal operation. Sponge iron deaerator automatic backwash initial use, the need for professional and technical personnel responsible for PLC devices, so as to avoid unnecessary losses caused by automated programs. Sponge filter consumption is very low, according to the quantity and quality of the different treatment, usually 3 - 6 months added once. Sponge filter Specifications: sponge filter specification :1.0-3 .0 mm ,3.0-5 .0 mm ,5.0-8 .0 mm ,8.0-12mm. Common specifications for 1.0-3.0mm ,3.0-5 .0 mm ,5.0-8 .0 mm. . Room temperature filter sponge iron oxygen technology, is a chemical oxygen. And thermal oxygen, oxygen analysis, resins and chemical oxygen oxygen compared to sponge iron oxygen technology into a small, easy to promote, oxygen effect, low running costs. Sponge iron deaerator massive sponge with high active oxygen filter, the oxygen filter is a sponge-like porous iron particles, the internal structure is regular porous mesh, surface area 80m2 / g, as the water DO provides a great reaction space, accelerates the oxidation reaction, the reaction is: 2Fe +2 H2O + O2 → 2Fe (OH) 2 Fe (OH) 2 adsorbed on the sponge iron particles, but it is in an oxygen-containing Water is unstable, it will be oxidized to ferric iron compounds, the reaction is: 4Fe (OH) 2 +2 H2O + O2 → 4Fe (OH) 3 ↓.
