Efficient-Clarification Candle Filter

The efficient-clarification candle filter is a high-efficiency, continuous-operation filtration device widely used in chemical, pharmaceutical, food, environmental protection and other industries to clarify liquids containing small amounts of solid particles.

 

The basic construction of candle filter

An efficient-clarification candle filter usually consists of a closed cylinder and a series of vertically arranged filter cartridges. Each cartridge resembles a candle, hence the name "candle" filter. The filter cartridge is the core component of the device, and its material selection and configuration directly affect the filtration effect and efficiency.

 

Filter cartridge and filter cloth

The filter cartridge is covered with a special filter cloth, which is carefully selected according to the characteristics of the raw material liquid to be filtered. For some special raw materials, it may be necessary to add filter aids, such as activated carbon or diatomaceous earth, to improve the filtration effect.

 

Formation of "filter cake layer"

When the liquid passes through the filter cloth, the solid matter will gradually accumulate on the surface of the filter cloth, forming a layer called the "filter cake layer". This layer of structure can effectively block the particulate impurities in the liquid due to its tiny voids, making the filtrate clear.

 

Filtering cycle and efficiency

As normal filtration progresses, the "filter cake layer" will gradually thicken, which will reduce the rate of filtrate passing through the filter cake layer, thus affecting the filtration efficiency. Therefore, regular removal of the "filter cake layer" is the key to maintaining filtration efficiency.

 

Anti-blow off cake and slag removal

When the system detects that the thickness of the filter cake layer exceeds the standard, the anti-blow cake procedure is usually initiated. This process is triggered by a signal from the pressure sensor. The system will reverse the flow of compressed air or other gases through the filter cartridge to help remove the filter cake layer. At the same time, a valve at the bottom of the cylinder will open to expel the falling solid material.

 

The reconstruction and new cycle of the filter cake layer

After the removal is completed, the system will rebuild a new "filter cake layer" and start a new round of filtration cycle. This process is automated, ensuring the continuity and productivity of the filtration operation.

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.
