In the field of industrial liquid filtration, the stability of equipment, ease of maintenance, and flexibility of filter bag replacement are often the key points that enterprises focus on. Recently, a water treatment enterprise located in Southeast Asia, during its production line upgrade project, introduced a batch of 2# bag filters for liquid impurity interception and clarification treatment in the process. This enterprise has been engaged in industrial water treatment and maintenance of circulating water systems for a long time, and has high requirements for the corrosion resistance, sealing performance, and daily maintenance efficiency of filtration equipment.
It is known that in the initial stage of the project, this enterprise used various types of filtration equipment, but in actual operation, it often encountered some problems, such as rapid aging of equipment sealing parts, insufficiently convenient filter bag replacement, and poor matching between the inlet and outlet connection methods and the existing pipeline system. These problems affected the continuous operation efficiency of the production line and increased the daily maintenance costs. Therefore, the enterprise compared multiple options during the equipment selection stage and finally chose the 2# bag filter of model JYSF-2#-304.
Technical Specifications & Material
This bag filter is made of SS304 stainless steel material, with the surface treated by sandblasting, which has good corrosion resistance and structural strength, and can adapt to the long-term contact with liquid in the water treatment environment. The sealing material is nitrile rubber (NBR), showing good sealing stability under normal liquid filtration conditions. The inlet and outlet of the equipment adopt 2-inch BSPT internal thread connection, side inlet and bottom outlet, which is relatively smooth in connection with the existing pipeline system, reducing the amount of renovation work. The cylinder diameter is 219mm, and the cylinder height is approximately 1200mm, belonging to the standard specifications of 2# bag filter, with moderate installation space requirements, making it easy to be flexibly arranged in the existing production line layout.
Operating Parameters & Versatility
In terms of operating parameters, the design pressure of this equipment is 10 bar, and it is equipped with a pressure gauge, which enables operators to observe the pressure changes in the system in real time. Each unit is equipped with 1 2# filter bag, with a size of 180×810mm, a filtration accuracy of 50 microns, and a material of PP. The enterprise also selected 2# filter bags with filtration accuracies of 1um, 5um, 50um, and 100um for different liquid media and different particle size scenarios for switching use. This flexible filter bag configuration enables the same equipment to cover multiple filtration accuracy requirements, reducing the need for repeated equipment purchases.
During actual use, the enterprise reported that the opening and replacement of the filter bag of the bag filter is relatively simple, and the daily maintenance workload has been reduced. The side inlet and bottom outlet structure design also helps to optimize the pipeline layout, making the on-site pipelines more orderly and reducing unnecessary elbow connections. In addition, the standard 50 micron PP filter bag performs stably in the conventional water treatment process and can effectively intercept suspended particles and impurities in the liquid, ensuring the stable operation of the subsequent process.
The project leader of this enterprise stated that the main reason for choosing this bag filter is its reliable material, standard specifications, strong filter bag adaptability, and convenient maintenance. After a period of operation observation, the equipment overall performance meets expectations, the filtration effect is stable, and the maintenance cost is controllable. The enterprise also plans to continue using similar equipment in other production lines to further improve the overall liquid filtration efficiency.
This application case indicates that the 2# stainless steel bag filter has good applicability in industrial water treatment and conventional liquid filtration scenarios. Its SS304 material, standard 2# specification, side-in bottom-out connection method, and multiple precision filter bag selection options can meet the filtration requirements under different working conditions, providing a stable, flexible and easy-to-maintain liquid filtration solution for foreign customers.
