High Filtration Efficiency Candle Filter

The high filtration efficiency candle filter is a fully automated, intermittent filter system that employs vertically arranged filter cartridges within a pressurized tank. It is designed for clarifying liquids containing a small amount of solids. This compact unit offers high productivity, dry cake discharge, and versatile cake handling methods.

 

The candle filter is available in a variety of sizes and configurations to suit different applications and flow requirements. It can be used as a standalone unit or integrated into larger systems, making it versatile and adaptable to a wide range of industrial processes.

Structure and Working Principle

The high filtration efficiency candle filter consists of multiple porous filter cartridges enclosed within a sealed vessel. These cartridges are covered with filter cloth (or other filtering media) that serves as the primary barrier for separating solids from the liquid. The filtration process begins by pumping the slurry into the filter vessel. As the slurry enters, the liquid passes through the filtering media and enters the porous core of the filter cartridges, eventually collecting at the clean liquid outlet for discharge.

 

Before the formation of a filter cake, the discharged "clean liquid" is recirculated back to the slurry inlet, allowing for continuous filtering until a filter cake of sufficient thickness and density is established. This filter cake acts as an additional barrier, enhancing the filtration efficiency. Once the desired filter cake is formed, a signal is sent to control the system, stopping the recirculation of the clean liquid. The clean liquid is then diverted through a three-way valve to the next processing stage, and the normal filtration process begins.

 

Advantages of the High Filtration Efficiency Candle Filter

1. High Filtration Efficiency. The combination of the porous filter cartridges and the filter cloth provides excellent filtration efficiency, effectively removing solids from the liquid.

2. Compact Design. The compact structure of the candle filter allows for a high degree of automation and integration into existing processing lines.

3. Dry Cake Discharge. The filter cake can be discharged in a dry state, which is beneficial for further processing or disposal.

4. Versatile Cake Handling. The filter design allows for various cake handling methods, including manual, pneumatic, or mechanical discharge.

5. Continuous Operation. With the recirculation of clean liquid during the initial stages of filtration, the candle filter can operate continuously until the desired filter cake is formed.

6. Easy Maintenance. The filter cartridges and filter cloth are easily accessible, allowing for quick replacement and maintenance.

 

Applications

The high filtration efficiency candle filter is widely used in various industries, including chemicals, pharmaceuticals, food and beverage, mining, and more. It is particularly suited for applications where clarification of liquids containing small amounts of solids is required.

 

Operation and Control

The operation of the high filtration efficiency candle filter is typically automated, with sensors and control systems monitoring various parameters such as filter cake thickness, pressure drop, and flow rates. These parameters are used to optimize the filtration process and ensure efficient operation.

 

Environmental Impact

By effectively removing solids from liquids, the high filtration efficiency candle filter contributes to environmental sustainability. It reduces the need for further treatment or disposal of contaminated liquids, thus minimizing the impact on the environment.

 

Operation

Maintenance of the high filtration efficiency candle filter is user-friendly, with replaceable filter candles and easily accessible components that minimize downtime and maximize productivity.

 

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.
