An overview of the removal of oxygen dissolved in the water, to prevent corrosion of boiler or other water equipment to ensure its safe and economic operation of great significance. For years, people have been the traditional method of oxygen due to the effects of harsh external conditions less than ideal oxygen effect, or can not operate economically distressed. The company introduced the patented technology, developed at room temperature filter deaerator, which overcomes the shortcomings of traditional methods of oxygen, since the market three years ago, proved that the dissolved oxygen content of the effluent can guarantee 0.05mg / L or less, has become a low-pressure boiler oxygen equipment replacements. Second, the mechanism of oxygen at room temperature filter oxygen iron with simple equipment, easy operation, low capital investment, low operating cost, as long as the effects of unstable oxygen to overcome the iron, the need for regular activation and other shortcomings, in fact, for industry The boiler is an ideal method of oxygen. The mechanism of oxygen at room temperature filter: Applying patented technology to produce sponge iron tablets, the main ingredient is iron, its long and short loose internal structure, specific surface area provides is 5-10 times that of ordinary iron, can make the oxygen in the water and iron rapidly complete oxidation reaction, the dissolved oxygen stable at 0.05mg / L or less, the reaction is: 2Fe + 2H2O + O2 → 2Fe (OH) 2 2Fe (OH2) + H2O + 1 / 2O2 → 2Fe (OH) 3 ↓ reaction product as long as certain intensity of backwash water can rinse (about 5 minutes). Sponge iron consumption is very low, according to the different water treatment and water quality, generally from March to June supplement once. After oxygen water increased after a small amount of iron (usually 0.2-0.5mg / L), it is still in line for the hot water boiler water quality standards prescribed by the state. But for steam boiler feed water or Fe2 +, there are strict requirements for water supply oxygen, iron can be installed in the existing deaerator, deaerator to remove the water, Fe2 +, to ensure the boiler feed water quality. The company has a variety of iron ion exchange equipment for users to choose. Third, the device features 1, can be achieved at room temperature, oxygen, water without heating; 2, stable and reliable effect of oxygen, dissolved oxygen content of the water stable ≤0.05mg / L, to meet the low-pressure boiler water quality standards; 3, the full range of equipment control mode according to user requirements to select automatic or manual control; 4, install, no special requirements, to overcome the heat, oxygen must be high-mounted vacuum inconvenience; 5, the device can be arranged low, small footprint, simple process; 6 For automatic deaerator is no need to install the backwash pump, the system is simple.
