Application of bag filters in the electronic industry

There are a large number of electronic product manufacturing enterprises. Various organic and inorganic substances are used in the production process, including heavy metals and many toxic and harmful substances. Pollutants (especially discharged wastewater) will produce a lot of poisonous and carcinogenic substances.

Compared with the metallurgy and chemical industry, the harmful impact of pollutants from electronic manufacturing on the social environment and people’s life is more hidden.

The bag filter has a reasonable structure, good sealing, and simple operation. Therefore, it is very suitable for wastewater treatment in the electronic industry.

The side leakage probability of the bag filter is small, which can ensure the effective filtration of pollutants. In addition, the filter bag can be replaced quickly, and the operation cost is minimal.

The inner surface of the filter is polished and very easy to clean.

When the bag filter works, the liquid flow direction is side in and side out or in and bottom out. The liquid medium is pressed or pumped into the bag filter barrel through the pressure in the pipeline. After the liquid medium passes through the filter material layer of the filter bag, the solid is retained in the filter bag, and the liquid part flows into the outlet to achieve the effect of separating pollutants.

When filtering high viscosity liquid, compressed air can be introduced through the exhaust valve to accelerate the discharge of residual liquid and shorten the waiting time. At this time, we should note that the air used for pressurized release must be stable, and the pressure shall not exceed the working pressure of the filter.

A bag filter is suitable for filtering cooling water, removing impurities in copper foil electrolytic stabilization cell, filtering chemical slurry, oil removal in copper foil production, etc. Bag filter provides a guarantee for the development of the electronic industry and improves economic benefits.

At the same time, bag filter plays a vital role in food processing, natural gas purification, ink, and other industries.
