304 316L Stainless Steel Multi-Bag Filter Housing

304 stainless steel is also known as 18/8 stainless steel because it contains about 18% chromium and 8% nickel. This proportion of alloy composition gives it good comprehensive properties, including excellent corrosion resistance, heat resistance, good mechanical properties and processing formability. 304 stainless steel is suitable for use in most fresh water and weakly corrosive media, such as daily water treatment, light industrial fluid filtration, etc. It is relatively low cost and is one of the most widely used stainless steel materials in industrial filtration equipment.

316L stainless steel adds 2% molybdenum to 304, which significantly improves its corrosion resistance in chloride ion environments, especially in highly corrosive environments such as seawater, swimming pool water treatment, and certain chemical product production. "L" represents low carbon content, which reduces the risk of sensitization corrosion after welding. Therefore, 316L stainless steel is more suitable for filter components that require frequent welding or work in high-temperature environments. In addition, 316L also has good heat resistance and intergranular corrosion resistance, and is the preferred material for high-standard hygienic environments such as the pharmaceutical and food industries.

The 304 316l stainless steel multi-bag filter housing is mainly composed of a filter container (housing), supporting net baskets, filter bags, and corresponding water inlet and outlet and seals. It pushes the liquid to be filtered into the filter through a pump or other means. The liquid flows through the filter bags from the outside in or from top to bottom, and the solid particles are trapped on the surface or inside of the filter bags, while the clean liquid flows out through the filter bags.

1. Filter container. Made of 304 or 316L stainless steel, it guarantees the strength and corrosion resistance of the equipment. The design of the container ensures the stable installation of the filter bag and the even distribution of the liquid.

2. Support basket. Located inside the container, it is used to support the filter bag to ensure that the filter bag does not deform when pressed, and at the same time, it is convenient for the installation and replacement of the filter bag.

3. Filter bags. Choose filter bags of different materials and pore sizes according to the requirements of filtration accuracy. Common ones include nylon, polyester, polypropylene, etc., which can intercept particles of different sizes. The size and number of filter bags determine the processing capacity and filtration efficiency of the filter.

4. Water inlet and outlet and seals. Water inlet and outlet are generally designed as flange connections, which are convenient for installation and maintenance. Nitrile rubber, fluororubber, etc. are commonly used for seals to ensure no leakage.

Parameters

Performance advantage

- High efficiency and large capacity. The multi-bag design significantly increases the filtration area, resulting in a large processing capacity per unit time, and the filtration efficiency can be easily improved by increasing the number of filter bags.

- Easy to maintain. Filter bag replacement is simple and quick, eliminating the need to disassemble the entire filter, reducing maintenance costs and downtime.

- Flexibility. Filter bags of different materials and precision can be selected according to actual needs to meet the filtration requirements under different working conditions.

- Corrosion resistance. 304/316L stainless steel material ensures long-term stable operation in harsh environments and extends the life of the equipment.

- Strong adaptability. Suitable for a variety of fluid media, from clean water to solutions containing certain concentrations of chemicals, it can be effectively filtered.

Application example

In the pretreatment of chemical raw materials and the purification of finished products, multi-bag filters are used to remove suspended solids and particulate impurities to ensure the purity of subsequent reactions or products.

1. Pharmaceutical industry. It is used for the refining and filtration of pharmaceutical liquids to ensure a sterile environment during the production of medicines and comply with GMP standards.

2. Food and beverage. In the production of fruit juice, beer, dairy products, etc., filters are used to remove solid impurities from raw materials to maintain product quality and taste.

3. Water treatment. Whether it is drinking water or industrial water treatment, multi-bag filters are an effective tool for removing suspended matter and particulate matter, protecting subsequent RO membranes, ultrafiltration and other precision equipment.

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
