Liquid Clarification Candle Filter

The liquid clarification candle filter marks a filtration device used to clarify liquids containing small amounts of solid substances. It is widely used in food, beverage, pharmaceutical, chemical and other industries. Unlike other types of filters, the candle filters use a unique filter cartridge design that can effectively remove particulate impurities in liquids and achieve liquid clarification.

Structure

The liquid clarification candle filter consists of the cylinder, filter element, filter cloth, pressure sensor and backflushing system.

- Cylinder: Cylindrical container for holding filter elements.

- Filter element: Porous cylindrical support body, with special filter cloth.

- Filter cloth: Select according to the characteristics of the raw material liquid to filter particulate impurities.

- Pressure sensor: Monitor the pressure in the cylinder to determine the thickness of the filter cake layer.

- Backflushing System: Composed of air or liquid, it is used to remove the filter cake layer.

 

Working principle

When the liquid flows through the candle filter, solid impurities will form a filter cake layer on the surface of the filter cloth. As the thickness of the filter cake layer increases, the rate of liquid passing through the filter cake will decrease, and the filtration efficiency will also decrease. At this time, the pressure sensor will detect that the pressure in the cylinder is rising, triggering the backflushing system start-up.

- Backflushing cake removal

The backflushing system ejects air or liquid from the bottom of the filter element, forming a strong airflow or liquid flow. These airflows or liquid flows initialize the filter cake layer and peel it off the surface of the filter cloth. At the same time, the valve at the bottom of the cylinder opens, and the filter cake layer is expelled from the filter.

- Reconstruct the filter cake layer

After the backflushing cake removal is completed, a new cake layer begins to reconstruct on the surface of the filter cloth. This process continues for a period of time until the cake layer reaches the optimum thickness and filtration efficiency is reached.

 

Advantages

- High filtration efficiency. The filter cake layer has tiny pores, which can effectively retain particulate impurities.

- Reusable. Filter elements and filter cloths can be used multiple times to reduce filtration costs.

- High degree of automation. Pressure sensors and backflushing systems are automatically controlled without manual intervention.

- Strong adaptability. Special filter cloth can be selected according to different raw material liquid characteristics.

- Easy to maintain. Backflushing system can quickly remove the filter cake layer, simplifying maintenance work.

 

Applications

The liquid clarification candle filter is widely used in the following fields:

- Food and beverages. To clarify fruit juices, beers, wines, cooking oils, etc.

- Pharmaceuticals. To clarify drug solutions, plasma, etc.

- Chemical industry. To clarify chemical raw materials, intermediates, etc.

- Water treatment. To clarify industrial wastewater, domestic wastewater, etc.

 

Selection

When selecting a candle filter, consider the following factors:

- Feature of raw material liquid: Solid content, particle size, viscosity, etc.

- Filtration efficiency requirements: Clarification required.

- Processing capacity: The amount of liquid to be handled per hour.

- Backflushing frequency: Determined according to the characteristics of the raw material liquid and the filtration efficiency requirements.

By considering these factors comprehensively, appropriate model of candle filters can be selected to meet specific application requirements.

 

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.
