The popularity of bag filters has garnered widespread attention from various enterprises. The equipment boasts numerous advantages in wastewater treatment, offering users superior water filtration capabilities. However, many are unaware that there are various types of bag filters. If customers plan to purchase this equipment, they need to pay attention to its selection principles.
The bag filter we refer to is a versatile and easy-to-operate multi-purpose filtration equipment. It is widely used in the chemical, petroleum, mining, and water supply industries. Applications include filtering industrial wastewater, recirculating water, waste oil treatment, and blast furnace water systems.
What are its selection principles like?
Nominal Pressure: Determine the pressure class of the filter based on the high pressure that may occur in the filtration pipeline.
2. Filter Resistance Loss Calculation: For water filters, under normal rated flow rate calculations, the pressure loss is 0.52 to 1.2 kPa.
3.进出口尺寸: The principle is that the inlet and outlet dimensions of the filter should not be smaller than the inlet diameter of the pump it is paired with, typically matching the diameter of the inlet pipe.
4. Selection of mesh count: Primarily consider the particle size of impurities to be intercepted, determined by the medium process requirements. Refer to the table "Filter Mesh Specifications" for the particle size range that various mesh sizes can intercept.
Filter Material: Generally, the filter material is selected to match the material of the connected process pipeline. For different service conditions, cast iron, carbon steel, low-alloy steel, or stainless steel filter materials can be considered.
For many manufacturing companies, what they need is a cost-effective water filtration system. Currently, bag filters have become the preferred choice for numerous enterprises due to their numerous advantages and strong functionalities. However, when making a purchase, it is advisable to follow the above selection principles.
