Beijing sponge sponge iron filter water fluoride removal agent

Sponge iron oxygen scavenger Products: As water oxygen scavenger, it is the use of a particle size of 200 mesh or less Fe3O4 powder bonded together after high temperature reduction made 2-5mm and 1-3mm there are two kinds of particle size . Replacement reaction because the restore process, a certain number of gaps, and voids when bonding the powder particles, so that oxygen scavenger like a sponge, high porosity, large surface area, activity is also very high, easy to oxygen and water, produced by the reaction Fe3O4, so as to achieve the purpose of oxygen. Luyuan brand sponge iron oxygen scavenger added anti-compaction agent, the oxygen process will not harden, easy backwashing and maintenance. After the product by the number of units, the effect is very good, water oxygen content can be reduced entirely 0.05mg / L or less, so as to achieve the purpose of oxygen, the reaction product is readily soluble in water flocculent precipitate, was blocked off, with certain intensity of backwash water can rinse. Sponge iron consumption is very low, depending on the quantity and quality of treatment, usually 3--6 months supplement once. Sponge iron has good reduction activity and high specific surface area characteristics, as water oxygen scavenger sponge size is 2-5mm, high porosity, easily reacts with oxygen in water to achieve the purpose of oxygen, the reaction product is not soluble flocculent precipitate in water, was blocked off, with a certain intensity of backwash water can rinse. I developed the company's sponge iron oxygen scavenger is the use of a redox reaction principle, except through the filter precipitate manner exclusion, after pipes, boilers and circulating water dissolved oxygen corrosion treated water dissolved oxygen content can be reduced to 0.03MG / L less oxygen at room temperature filter sponge is a new way of oxygen appeared in recent years, because of its low investment, low operating and maintenance costs, the use of safe and good effect of oxygen and other characteristics are increasingly being applied to the boiler , circulating water like oxygen. The key factor applied at room temperature filter sponge iron deaerator oxygen effect is sponge iron filter performance. 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 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 working principle of oxygen at room temperature filter is a chemical oxygen, which uses specialized production of reactive sponge iron (DRI) to remove dissolved oxygen, the main component of sponge iron, its porous internal structure, providing a ratio surface area of ??5-10 times the ordinary iron, oxygen and iron in the water can occur 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 with the water flowing through the rest of the sponge iron When the 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. After the product by the number of units, the effect is very good, water oxygen content down to 0.05mg / L or less, and deal with every cubic meter of water consumed only about 25g, truly high-quality, low-cost operation. The softened water because they do not easily 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 features of the technical characteristics: Technology and working principle sponge iron deaerator used has the following characteristics: 1) can be achieved at room temperature, oxygen, water without heating; 2) the system can supply at any time, may need time to prepare, but also may not require an oxygen tank; 3) effect of oxygen stable and reliable, the dissolved oxygen content stabilize ≤0.05mg / L, in line with the low-pressure boiler water quality standards; 4) installation without special requirements, to overcome the heat, oxygen must be high-mounted vacuum inconvenience; 5) devices can lower layout, the process is simple, without excessive height requirements. Features: The new sponge iron filter deaerator launched in the country for several years, the early design of the device structure and process have some shortcomings gradually exposed, and sometimes a great impact on system operation in actual operation. Combined with a number of user experience for the inadequacies of earlier designs, the Company adopted new design ideas, imported components and advanced control technology design and production of sponge iron filter deaerator, has the following characteristics: 1) processes more simple and reasonable, the device simple and compact structure, easy operation and maintenance; 2) control high degree of automation, the system can automatically backwash based on time or work pressure loss, without manual operation, timely backwash eliminates oxygen scavenger agglomeration circumstances, to reduce water consumption, the equipment is always in good working condition; 3) Equipment with dual tank structure or a single pot dual-chamber structure, continuous production of water, if the water pressure is sufficient, even when the backwash without interrupting production of water, so after working-level system more stable and reliable; 4) the device automatically backwash water using anaerobic further improve the backwash effect, reduce water consumption, oxygen scavenger consumption. 5) automation system power consumption is very low, with manual override, backwash operation can be carried out only one button.
