DN250 390t/h large-flow security filter for power plant

1.The production of stainless steel large-flow security filter:

The stainless steel large-flow security filter protects the following equipment components in the liquid filtration system. It is often used for the solid-liquid separation of various suspensions after sand filtration (coarse filtration), before ultrafiltration or reverse osmosis, and environmental requirements. Relatively high, relatively high filtration accuracy of chemical liquid filtration to ensure the water quality filtration accuracy and protect the membrane filter element from damage by large particles. The filter medium is more commonly used when the filter medium is water, so the security filter belongs to the water filter. Fine filtration. The shell of the cylinder is generally made of stainless steel. The interior uses PP melt blown, wire-fired, folded, titanium filter, activated carbon filter and other tubular filter elements as the filter element. When the filter is running, the fluid medium will make the original liquid pass through the filter element under pressure. Staying on the pipe wall, the clean medium flows out through the filter element, so as to achieve the purpose of filtration.

2.Product performance characteristics of stainless steel large flow security filter:

1) The security filter can withstand higher filtration pressure and can effectively remove suspended solids and rust in the liquid;

2 The filter element can be made of a variety of materials to meet the needs of various fluid filtration;

3） Small size, large filtering area, small resistance and long service life;

4） Resistance to acid, alkali and other chemical solvents;

5） High filtration precision, uniform pore size of the filter element, high strength, high temperature resistance, and the filter element is not easy to deform;

6)Small filtration resistance, large flux, strong dirt interception ability and long service life;

7) The filter element material has high cleanliness and no pollution to the filter medium;

8)Low price, low operating cost, easy to clean, and the filter element can be replaced.
