sponge iron as filter to remove oxide from the boiler's water. 0- 4 mm , 3- 20 mm . T fe 85% min.
The sponge iron possesses high reduction activate nature and high specific surface area. As oxide removal agent for water, its sponge granular is 2- 5 mm , its poriness percentage is very high, and having large specific superficial area. it is very activative, so it can react with the oxide in the water. This reaction can produce Fe3O3, in this way, to remove the oxide. The reaction product is cotton shaped precipitation, which is intercepted halfway, and it can be washed clearly by backwashing water. Hardness 57 asy mm etry coefficient k80?1. 8 poriness 30- 50% ashes <0. 51 Working theories
The co mm on temperature oxide removal belongs to the chemistry method, which uses the special activated sponge iron to remove the oxide in the water, the sponge irons main ingredient is iron, its inside structure is very loose and having many holes, it has a superficial area which is 50- 100 thousand times as the co mm on scrap iron. It can make the oxide in the water to react with iron i mm ediately and totally, and make the dissolved oxide keep steady under 0. 05mg/ L, the reaction formula is:
2Fe2+ + 2H2O + O2>2Fe (OH) 2 4Fe (OH) 2+ 2H2O +O2>4Fe (OH) 3 2 The reaction product Fe (OH) 2Fe (OH) 3 are cotton precipitation which can not dissolve in water, which will be intercepted when it flows with the water passing other sponge iron granules. The precipitation can be washed clearly by a certain intensity of reverse washing water flow.
The consumption of sponge iron is very low, according to the waters quantity and quality, usually, it needs to be supplemented each 3- 6 months.
As oxide removal sponge iron, Only when the Fe3O4s granule diameter is lower than 200 mesh, it can glue with each other granule, and the bigger granule diameter is 2- 5 mm . Because the reduction process happens replacement reaction, it formed many pores, and also many pores have been shaped when powdery micro granules glue together. This makes the oxide removal agents pores increase and the superficial area enlarge. Also, since it is produced directly by reduction of primaryore, so it is pure, and very activated, and easily to react with the oxide in the water to produce Fe3O4, at last to remove oxide. Meanwhile, its usage efficiency can exceed 90% .
3 Since it concludes certain quantity of inclusions, so the granule can only be connected by weak bond, so basically it can not be rusted into a mess. It has been used by many factories, and the effect is very good. When the water has been treated, which concludes oxide only 0. 06mg/ L, to treat the waste water, each cubic meter of water only cost 25g sponge iron, so it is really a good quality and low cost product.
Because if the water hasnt been softened, it will make the oxide removal surface inactivated and the oxidation will slow down, so it needs to be oxidizing firstly then to be treated. When it has been used for some time, it should be reverse washed. 2. Main specialists
1) It can remove the oxide in the co mm on temperature, the coming water doesnt need to be warm.
2) The system could supply water any time, it doesnt need to prepare, nor need oxide removal container. 3) The oxide removal effect is very steady, when the water has been treated, its oxide content is lower than 0. 05mg/ L, which cater to low pressure boiler water quality standard.
4) The fixing doesnt need specific requirement, and it also overcomes the inconvenience of the heating power, vacuums high position fixing .
5) The equipment can be placed lowly, the technique is simple. Product characteristic
