Boiler put into use, that is a long period of high temperature water environments. At high temperature, oxygen and water contained in the boiler furnace wall, furnace tube reaction, severe corrosion of boilers, especially in the vapor at the interface, the more intense corrosion. Therefore, important occasions where the use of boilers, boiler feedwater are necessary to reduce the oxygen content of the water. The method commonly used is the addition of a dedicated boiler feed water deaerator. Over the past method of oxygen deaerator used are: thermal oxygen, vacuum oxygen, oxygen and other analytical. Their common feature is the large investment and high operating costs, an area of ??large, complex operation, poor reliability, and sponge iron in exchange medium, which greatly simplifies the response program, and easy to backwash, can be reused. Main features: room temperature oxygen, no heating, thermal oxygen to overcome the energy consumption; no chemical pharmaceutical, chemical oxygen to avoid environmental pollution of water quality; good sponge effect of oxygen???. The oxygen content in the treated water can be stabilized at 0.005㎎ / L or less;? Installation without special requirements, overcome heat, oxygen must be high-mounted vacuum inconvenience, and covers an area of ??greatly reduced;? Simple structure, reliable, construction, maintenance low-cost, long-life, non-toxic, do not pollute the environment;? normal operation, automatic operation, no manned. Instructions requires water pressure> 0.25Mpa, should be added if enough pressure pumps and intermediate tanks;? Backwash water tap water or well water, the backwash water pressure> 0.25Mpa, the reaction strength requirements 16-25L / S · m2;? Manual backwash time to grasp the deaerator inlet and outlet can be used to determine the pressure, when the import and export water pressure> 0.15Mpa backwash. Can also be monitored to determine the oxygen content of the water outlet, when the oxygen content exceeded, you should backwash;? Automatic deaerator available time control, usually every 24 hours backwash 20-30 minutes;? Oxygen tank to air isolation measures.
