Top Quality Automatic Operation Candle Filter

The top quality automatic operation candle filter utilizes vertically arranged filter elements within a pressure vessel to achieve efficient filtration. It is specifically designed for clarifying liquids containing a relatively low concentration of solids. This compact filtration system offers high productivity, dry cake discharge, and versatile cake handling capabilities.

 

The candle filter consists of multiple porous filter elements, or candles, housed within a sealed container. Over these elements, a filter cloth or other suitable filter media is fitted to capture the solids.

 

During operation, slurry is pumped into the filter, where the liquid portion passes through the filter media and into the center of the filter elements. The clarified liquid, or filtrate, then flows to a collection point and is discharged. Before a filter cake has formed on the filter elements, the filtrate is recirculated back into the filter to continue the filtration process. This recirculation continues until a sufficient filter cake has built up to meet the filtration criteria.

 

Once the filter cake has reached the desired thickness, a signal is sent to stop the recirculation of the filtrate. At this point, the filtrate is directed through a three-way valve to the next stage of the process for further use. The filter cake, meanwhile, remains on the filter elements until it is ready to be discharged.

Advantages of Candle Filters

1. High Productivity. Candle filters offer high filtration rates due to the large surface area provided by the multiple filter elements.

2. Dry Cake Discharge. The filter cake is discharged in a dry state, eliminating the need for additional drying processes.

3. Versatile Cake Handling. The filter cake can be handled in various ways, including manual discharge, automated discharge, or reslurrying for further processing.

4. Compact Design. Candle filters are compact and require minimal space for installation and operation.

5. Automatic Operation. The filtration process is fully automated, minimizing operator intervention and ensuring consistent performance.

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.
