Environmental sponge iron filter, sponge filter material, Wuhan source water filter Wholesale

Sponge iron filter (also called oxygen scavenger) using high-quality ore, the use of oxidation-reduction reaction principle, except through the filter precipitate manner exclusion, after the pipeline, boiler water is circulating oxygen corrosion treated water dissolved oxygen content can be achieved 0.05 mg / L or less, and the oxygen scavenger having backwash frequency is low, high compressive strength, not powder, not structural plate, large surface area. High activity, good regeneration and so on. The treated sponge iron activated oxygen scavenger, spongy porous iron particles, the dissolved oxygen in water to mention sponge iron filter (also called oxygen scavenger) using high-quality ore, the use of oxidation-reduction reaction principle, through the filter In addition to the exclusion of Formula lake manner, for pipes, boiler corrosion by dissolved oxygen is circulating water dissolved oxygen content in the treated water can reach 0.05 mg / L or less, and the oxygen scavenger having backwash frequency is low, high compressive strength, not powder , does not end boards, large specific surface area. High activity, good regeneration and so on. After activation of the oxygen scavenger sponge iron, spongy porous iron particles, the dissolved oxygen in water to provide an opportunity to react with the active iron, accelerate the oxidation-reduction 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 ↓ Application: can be used for a variety of boilers, heat pipes water, industrial cooling water, etc. need to remove dissolved oxygen in place. First, the sponge iron works in water treatment project in oxygen at room temperature filter is a chemical oxygen, is the use of specialized production of reactive sponge iron (DRI) to remove dissolved oxygen, the main component of sponge iron, its loose porous internal structure, specific surface area provides 5-10 times the ordinary iron, oxygen and iron in the water can take place quickly and thoroughly oxidation, dissolved oxygen stable at 0.05mg / L or less, 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 easily soluble in water flocks, when As the water flows through the rest of the sponge iron particles are blocked off, as long as a certain intensity of backwash water can rinse (about 5 minutes). Sponge iron consumption is very low, according to the quantity and quality of the different treatment, generally 3-6 months supplement once. (Through an increase in oxygen after a small amount of iron ions, usually 0.2-0.5mg / L, the hot water boiler is still in line with state water quality standards, but for the stringent requirements of steam boiler feed water or have water supply Fe2 + oxygen, it can be installed in addition to iron equipment, removal of Fe2 +, this center with a variety of ion exchange in addition to iron means for users to choose.) as the sponge iron is the use of water oxygen scavenger particle size of -200 mesh The following Fe3O4 powder bonded together, particle size of about 2-5mm. Replacement reaction because the restore process, a certain number of gaps, and voids when bonding the powder particles, so that oxygen scavenger high porosity, large surface area, but also because the original ore direct reduction of income, relatively pure, so highly reactive oxygen reacts with water pole generate Fe3O4, so as to achieve the purpose of oxygen. At the same time utilization also increased to 90%. And because a certain amount of impurities, so that in the process of oxygen is a weak bond between the particles can only be connected to the basic stainless steel die into the group. The softened water is not easy to make the oxygen scavenger surface passivation, it slows down the oxidation, and the impact effect of oxygen, it should be softened and then oxygen. After a period of time, should be backwashed. Second, the main technical features of sponge iron in the water treatment project: technical and working principle sponge iron deaerator used has the following characteristics: 1. normal operation without heating, to overcome the heat, oxygen and weaknesses vacuum heating energy consumption ; it can be achieved at room temperature, oxygen, water without heating; 2. area, accounting for a small space, easy to install, to overcome the heat, high-mounted vacuum oxygen inconvenience; it works: sponge iron oxygen scavenger is activated Processing After high active filler, is spongy porous iron particles, the dissolved oxygen in water to provide the conditions to react with the active iron, when the water through the sponge iron containing oxygen, water, oxygen and iron oxidation reaction occurs completely, thereby eliminating the dissolved oxygen content of the water. The system can supply at any time, may need time to prepare, but also do not need an oxygen tank; 3 is not dissolved in water soft floc, when it accumulated to a certain extent, it can drain through the backwash, to make sponge iron recovery The initial oxygen capacity. Effect of oxygen stable and reliable, the dissolved oxygen content stabilize ≤0.05mg / L, in line with the low-pressure boiler water quality standards; Features: The new sponge iron filter deaerator launched in the country for several years, the early design of the device structure and processes The actual operation has some shortcomings gradually exposed, and sometimes a great impact on system operation.
