Room temperature filtering sponge iron deaeratorIt has good reducing activity and high specific surface area characteristics. As a water deoxygenation agent, the sponge has a particle size of 2-5mm, extremely high porosity, large specific surface area, high activity, and is easily reacted with oxygen in water to generate Fe3O3, thus achieving the purpose of deoxygenation. The reaction product is a flocculent precipitate that is not easily soluble in water, which can be intercepted and washed clean with a certain strength of backwash water.

Deoxygenation can be achieved at room temperature without heating the inlet water

Working principle of room temperature filtering sponge iron deaerator:

The room temperature filtration sponge iron deoxygenation equipment belongs to chemical deoxygenation. It uses specially produced active sponge iron (direct reduced iron) to remove dissolved oxygen in water. The main component of sponge iron is iron, and its loose and porous internal structure provides a specific surface area 50000 to 100000 times that of ordinary iron filings, which can cause rapid and thorough oxidation reaction between oxygen and iron in water, stabilizing dissolved oxygen below 0.05mg/l.

The reaction equation is: 2Fe2++2H2O+O2 → 2Fe (OH) 2 4fe (OH) 2+2H2O+O2 → 4fe (OH) 3

The reaction products fe (oh) 2 and fe (oh) 3 are flocculent precipitates that are not easily soluble in water. When they pass through other sponge iron particles with the water flow, they are intercepted and can be washed clean with a certain strength of backwash water flow (about 5 minutes).

Deoxygenation can be achieved at room temperature without heating the inlet water

Main features of room temperature filtration sponge iron deaerator:

Deoxygenation can be achieved at room temperature without heating the inlet water;

The system can supply water at any time, without the need for preparation time or a deoxygenated water tank;

The deoxygenation effect is stable and reliable, and the dissolved oxygen content in the effluent is stable at ≤ 0.05mg/l, which meets the water quality standards for low-pressure boilers;

There are no special requirements for installation, overcoming the inconvenience of high-level installation for thermal and vacuum deoxygenation;

The equipment can be arranged in a low position, the process is simple, and there are no high height requirements. Product features: The new sponge iron filter type deaerator has been launched in China for several years. The early designed equipment structure and process have gradually exposed some shortcomings in actual operation, sometimes causing significant impact on system operation. Based on the practical experience of several users and the shortcomings of early design, our company adopts a new design concept, original imported components, and advanced control technology to design and produce sponge iron.
