Stainless Steel Housing Bag Filter

The stainless steel housing bag filter contains the following parts: filter cylinder, filter cylinder cover, quick opening mechanism,filter bags and stainless steel filter bag reinforcement screen. The filter cylinder is made of stainless steel, providing excellent decay resistance. The filter bag is the core part of the bag filter, and its material and structure directly affect the filtration effect and service life of the filter.

 

During operation, the liquid to be filtered enters the bag filter through the liquid inlet. The position of the liquid inlet is usually designed on the side or top of the filter to ensure that the liquid can be evenly distributed above the filter bag. Under the action of pressure, the liquid passes through the filter bag from the top down or from the outside to the inside. The microporous structure of the filter bag can effectively intercept impurities such as solid particles, suspended solids and microorganisms in the fluid.

 

Impurities with larger particles will be trapped on the surface and inside of the filter bag. The clean liquid will pass through the pores of the filter bag, collect along a preset path, and finally flow out from the liquid outlet at the bottom or side of the filter.

Choosing the right filter bag is the key to ensuring the filtration effect. When choosing a filter bag, factors such as the chemical properties of the fluid, temperature, operating pressure, pH value, viscosity, type and content of impurities need to be considered.

Advantages of bag filters

The stainless steel housing bag filter offers the following significant advantages:

1. Simple structure. The bag filter is compact, concise, and easy to install and maintain.

2. Flexible operation. The quick-opening device makes it easy and fast to maintain and replace the filter bag, greatly improving work efficiency.

3. Consumables economy. Filter bags, as wearing parts, are relatively inexpensive and easy to replace, reducing operating costs.

4. Stable performance. High-quality filter bags and tight sealing design ensure the filtration effect and service life of the filter.

5. Strong adaptability. Suitable filter bag materials and specifications can be selected according to different working conditions to meet various complex filtration requirements.

6. Environmental protection and energy conservation. Reducing waste generation and energy consumption, in line with the concept of green environmental protection.

 

Working principle of the bag filter

The working principle of the stainless steel housing bag filter is relatively simple. When the liquid containing impurities enters the filter, it will first enter the cylinder through the feed port. In the cylinder, the liquid will be forced to filter through the filter bag. Since the pore size of the filter bag is very small, it can effectively trap tiny impurities in the liquid. The liquid filtered by the filter bag will be discharged through the discharge port of the filter to achieve purification of the liquid.

 

In the filtration process, the filter bag plays a key role. The material selection of the filter bag directly affects the filtration accuracy and service life of the filter. Generally speaking, high-quality filter bags can withstand high pressure and temperature, while having good chemical stability and wear resistance. This allows the bag filter to maintain excellent filtration results under various complex working conditions.

 

Filter bag replacement or cleaning

When the filter bag reaches saturation or the pressure difference is too high, it needs to be replaced or cleaned. For single-use or difficult-to-clean filter bags, the old filter bag can be directly removed and a new filter bag can be installed. For those filter bags that can be cleaned and reused, it is necessary to close the inlet and outlet valves to release the pressure inside the filter, then open the filter cover or quick-opening mechanism, remove the filter bag for cleaning, and then put it back in place after cleaning.

 

Selection of bag filters

1. According to the nature of the filter medium. When selecting a filter bag, it is necessary to choose the appropriate filter bag material and structure according to the nature of the filter medium, such as particle size, humidity, temperature, corrosiveness, etc.

2. According to the filtration area and processing capacity. According to the required filtration area and processing capacity in the production process, choose the appropriate size of the bag filter.

3. According to the degree of automation. According to the production requirements, choose whether the bag filter of the automatic control device is required.

 

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.
