High Filtration Capacity Multi-Bag Filter

The high filtration capacity multi-bag filter is a kind of high-efficiency liquid filtration equipment, which has the advantages of high filtration capacity, high filtration flow rate and high filtration accuracy, and is widely used in chemical, food, pharmaceutical and other industries.

 

The high filtration capacity multi-bag filter employs multiple filter bags to filter the liquid. The liquid to be filtered enters the filter from the inlet, and the liquid is evenly distributed into each filter bag through the dispenser. Inside the filter bag, when the liquid passes through the filter cloth, the suspended matter is intercepted by the filter cloth, and the clean liquid flows out through the filter cloth. The filtered liquid collects from the bottom of the filter bag to the outlet, and finally flows out of the filter. At the same time, the filtered filter residue accumulates in the filter bag. As the filtration proceeds, the thickness of the filter residue layer gradually increases, and the filtration resistance also increases. In order to maintain the filtration effect, the filter bag needs to be cleaned or replaced regularly.

 

Structural features

The high filtration capacity multi-bag filter is mainly composed of shell, filter bag, filter plate, distributor, inlet and outlet pipes and other components. Its structural characteristics are as follows:

1. Shell

The shell of the multi-bag filter is usually made of stainless steel, which has high strength and corrosion resistance. There are multiple filter bag installation positions inside the shell to facilitate the installation and replacement of the filter bag.

2. Filter bag

The filter bag is the core component of the multi-bag filter, and its material, filtration accuracy and other parameters directly affect the filtration effect. The filter bag is usually made of synthetic fiber materials such as polyester and polypropylene, which have good strength and corrosion resistance. The filtration accuracy of the filter bag is usually between 0.5μm and 800μm, which can be selected according to actual needs.

3. Filter plate

The filter plate is located at the bottom of the filter bag to support the filter bag and prevent deformation of the filter bag. The filter plate material is usually the same as the shell material to ensure the corrosion resistance and strength of the entire filter.

4. Dispenser

The dispenser is used to evenly distribute the liquid to be filtered into each filter bag to ensure that each filter bag can be fully filtered. The dispenser is usually made of stainless steel, which has high strength and corrosion resistance.

5. Inlet and outlet pipelines

Multi-bag filter inlet and outlet pipelines are used to connect the filter to external equipment, usually made of stainless steel to ensure the corrosion resistance and strength of the entire system.

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.
