1, Summarize
Remove soluble in water, the oxygen to prevent the boiler water or other equipment corrosion, ensure the safe and economic operation has important significance. However, people have been in DuoNian for traditional oxygen method (thermal deaeration, vacuum oxygen, REDOX resin oxygen, analytical oxygen, steel scurf oxygen, etc.), by demanding outside condition the influence, short of the ideal oxygen effect or not economic operation and frustration. Microcomputer control room temperature filtration type deaerator, overcome traditional oxygen method shortcomings, the water dissolved oxygen content in 0.05 mg / 1 below. This achievement has been become oxygen equipment upgrading of products.
2, Working principle
Let contains oxygen, water through the special sponge iron filter material (the filter material has great specific surface area, is copper scurf 5-100000 times, the oxygen and iron happens the oxidation reaction of thoroughly, and its chemical reactive for:
Fe 2 + 2 + 2 Fe and H20 O2 (OH) 2
2 Fe (OH) 2 + H20 + 1/2 O2-2 Fe (OH) 3
Reaction to the floe soft things, using when sponge iron response surface to a certain extent, because the sponge iron filter layer depths of dissolved oxygen oxygen is low, can't make Fe (OH) 2 all oxidized to Fe (OH) 3, so in the water with a small amount of Fe + 2, generally in 0.5-0.8 mg/L or so, the increase of the hot water boiler is still a small iron that accords with national regulation, water quality for steam boiler need to configure the iron removal in. In addition to the iron have ion exchange method and manganese sand filter method. The former expires, the latter with NaCl solution regeneration failure with water after washing, on the ion exchange chromatography for three price of iron poisoning of resin, the iron pollution to prevent bivalent iron in the regeneration process translated into three price, while the iron ion in the following measures:
Every time the resin bed regenerative in renewable punishment to join in the equivalent of 1% of the Na2SO3 NaCl dosage.
After four to five cycle after the operation to join equivalent to 1.5% of the NaHSO3 NaCl dosage
3, main characteristics
3.1 normal oxygen, no heat. Overcome the thermal deaeration, vacuum oxygen must be heating energy dissipation faults.
3.2 high efficiency and stability, oxygen levels in the water stable 0.05 mg/LFA, reached the medium voltage boiler water quality standards.
3.3, equipment whole province investment assembly factory, small volume, cover an area of an area small, low installation, low operating cost, microcomputer automatic control.
3.4 deaerator and in addition to the packing are avirulent insipidity iron, hot water boiler steam is produced and harmless to the human body.
