This enterprise has long been troubled by unstable filtration efficiency and frequent filter bag replacements in its liquid filtration process. The main processing involves chemical liquids and intermediate materials, and there are high requirements for the corrosion resistance, pressure-bearing capacity, and continuous operation stability of the filtration equipment. The original filtration equipment had a rapid increase in pressure difference when handling large flow rates, resulting in increased maintenance frequency and affecting the production rhythm.
After comparing various filtration schemes, the enterprise finally selected a 7-bag stainless steel bag filter, model JYMF-7P2. The equipment is made of SS304 stainless steel, with sandblasted surface treatment. The design pressure is 1.6 MPa, the working pressure is 1 MPa, the inlet and outlet are DN250 flanges, and the side inlet and bottom outlet structure. It can well match the on-site pipeline layout and process requirements.
This filter can be equipped with 7 2# PP filter bags, with a filter bag size of 180×810mm, a filtration accuracy of 100 um, and a plastic inward folding design. Compared with the original equipment, the 7-bag structure significantly increases the single-unit filtration area and processing capacity. In large-flow conditions of chemical liquids, it can maintain a relatively stable operating pressure difference and reduce the frequency of filter bag replacement. The cylinder wall thickness is 5 mm, with high structural strength, and it is suitable for long-term continuous operation.
The customer reported that after the equipment was put into operation, the overall efficiency of the liquid filtration process was improved, the filter bag replacement cycle was extended, and the daily maintenance operation was also more convenient. Due to the use of standard DN250 flanges and side inlet and bottom outlet design, the on-site installation and connection were smooth, and no significant changes were made to the original pipeline system.
The project leader of the enterprise stated that the main reason for choosing this 7-bag bag filter was its SS304 stainless steel shell’s corrosion resistance and structural strength, as well as the high throughput advantage brought by the multi-bag design. For scenarios requiring large flow rates and continuous operation, such equipment has good adaptability.
Currently, this equipment has been operating stably at the customer’s site. The customer stated that if there are similar filtration requirements in other production processes in the future, they will also give priority to the same type of 7-bag stainless steel bag filter to further improve the efficiency and stability of the overall liquid filtration system.
