  What are the different filter bag materials


Bag filter filtration material made of different materials, each has its different ways of filter, filtration efficiency and filtration precision, even using the same filter material, when the filtrate temperature, viscosity and velocity or filtrate quality and the effect of impurity content change filter will change according to the actual working condition, please select the most appropriate filtering material.


There are many kinds of filter materials with different materials, and different filtrates have different physical and chemical characteristics. In the process of filtration, the filter material must be compatible with it, can not have chemical reactions, and the filter material must also face the same pressure and temperature changes as the filtrate, the filter material must be able to maintain its fixed structure, the aperture does not change, can not soften, crack or release the composition, to provide a stable and uniform filtration quality.


Different filter materials have different physical and chemical characteristics. Please refer to the following table to select the appropriate filter materials


In general, the filtering polarity such as relatively high acid and alkali salt filtrate, choice of quality of the filter material of PP polypropylene (PP) filter solvent polarity such as low filtrate, can choose PE polyester (polyester) or NY Nylon (Nylon) quality of the filter material.


How long does it usually take to replace the filter bag of the bag filter?


Bag filter is a kind of multi-purpose filter equipment with novel structure, small volume, simple and flexible operation, energy saving, high efficiency, airtight work and strong applicability. Bag filter is a new filter system. The bag filter consists of a stainless steel cylinder, a supporting net basket and a filter bag. The liquid flows in through the inlet and flows out through the outlet after filtering through the filter bag. Impurities are intercepted in the filter bag. The liquid to be filtered goes through the inlet of the filter, and the intercepting particles and impurities of the filter bag are intercepted in the filter bag, so that the filtration system is easy to clean. The design of the handle inside the filter bag makes the replacement of the filter bag quick and easy.


The inlet and outlet design of bag filter generally adopts side bottom outlet mode, which makes it easy and quick to replace the filter bag.
