Simple-Structure Bag Filter

The simple-structure bag filter is a simple but ingeniously designed filtration device. Its core part is the filter bag, a filter medium made of fine materials, capable of capturing particles of different sizes. The entire filter system is supported by a metal mesh basket to ensure that the filter bag maintains a stable opening state during operation, thus ensuring stable flow and filtration effect.

 

The simple-structure bag filter can handle large flow rates and are suitable for rapid filtration of large quantities of liquids. Good sealing performance ensures that there will be no leakage during the filtration process, ensuring filtration quality and working environment hygiene. Since the filtration process is mainly physical interception, there is basically no material consumption.

 

Working principle of the bag filter

1. The liquid enters the bag filter through the inlet and flows through the metal mesh basket.

2. Impurities in the liquid are blocked by the metal mesh basket and intercepted inside the filter bag.

3. The filtered cleaning liquid passes through the filter bag and flows out from the outlet.

4. After a certain amount of impurities have accumulated in the filter bag, the bag filter can continue to be used by replacing the filter bag.

 

Structural characteristics of the bag filter

1. Metal mesh basket. The metal mesh basket serves as a support for the filter bag and a preliminary filter for the liquid.

2. Filter bag. The filter bag is made of high-quality synthetic or natural fibers, providing high filtration efficiency and strength.

3. Inlet and outlet. The inlet and outlet are equipped to facilitate the flow of liquids while preventing the filter bag from falling off.

4. Flange. A flange is set at the connection between the filter and the pipeline for easy installation and disassembly.

5. Shell. The shell is made of high-quality carbon steel or stainless steel, providing high strength and corrosion resistance.

 

Operation process of the bag filter

1. Preparation. Preparation work before turning on the filter, including checking whether the filter is in good condition, whether the connecting pipes are unblocked, and confirming the working pressure.

2. Start the filter. Open the inlet valve, the liquid enters the filter, is filtered through the filter bag, and flows out from the outlet.

3. Monitor the filtration process. During the filtration process, always pay attention to the operating status of the filter, such as filtration speed, pressure, etc., to ensure the filtration effect.

4. Replace the filter bag. After a certain amount of impurities have accumulated in the filter bag, close the inlet valve, open the filter housing, and remove the filter bag for replacement.

5. Clean the filter. After replacing the filter bag, clean the filter to ensure the filtration effect for the next use.

6. Close the filter: After completing the filtration task, close the inlet valve and stop the filter from running.

 

Advantages of the bag filter

1. High filtration efficiency. Using high-quality filter bags, the filtration effect is significant.

2. Simple structure. The bag filter is compact and takes up little space.

3. Easy maintenance. The filter bag is easy to replace and easy to clean.

4. Strong adaptability. The bag filter is suitable for filtration of various liquids, with adjustable filtration accuracy.

5. Good safety. The bag filter runs stably and has a low failure rate.

 

Application

Widely used in chemical, food processing, pharmaceutical, coating, oil treatment, water treatment and other industries for purification, separation, recycling and other processes.

 

Choice of the filter bag

The filter bag is the core component of the simple-structure bag filter, and its material and accuracy directly affect the filtration effect. To choose the right filter bag, you need to consider the following factors:

1. Filtration accuracy. Choose the appropriate filtration accuracy according to the size of the particles to be removed.

2. Material. Considering compatibility and durability, materials that can resist corrosion of the filtered material should be selected.

3. Differential pressure. The maximum allowable differential pressure during operation is an important parameter when selecting a filter bag.

4. Capacity. The capacity of the filter bag determines how much material it can filter before reaching clogging.

 

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.
