Automatic Backwash Filter With Good Filtering Effect

The automatic backwash filter with good filtering effect marks an essential component in various industrial and commercial applications, providing reliable and efficient filtration of particulate contaminants. It aims to remove particulate contaminants from high-flow, high-velocity, low-viscosity fluids. This self-cleaning filtration device is widely used in various industrial and commercial applications, including water treatment, chemical processing, food and beverage manufacturing, and more.

 

The automatic backwash filter operates on the principle of depth filtration. As the fluid enters the filter through the inlet, it passes through a filter element, which traps the particulate contaminants. The filtered fluid then exits the filter through the outlet.

 

Automatic Backwash Mechanism

The automatic backwash mechanism is triggered when the pressure drop across the filter element reaches a predetermined setpoint. This pressure drop indicates that the filter element has accumulated a significant amount of contaminants and needs to be cleaned.

 

The backwash process initiates by opening a valve that directs a portion of the filtered fluid back through the filter element in the opposite direction. This reverse flow dislodges the accumulated contaminants from the filter element and flushes them out through a dedicated drain port.

 

Control System

The automatic backwash filter is equipped with a control system that monitors the pressure drop across the filter element and initiates the backwash process as needed. This control system can be programmed to operate on a timed interval or differential pressure basis.

Selection Criteria

When selecting an automatic backwash filter, the following factors should be considered:

1. Flow rate. The flow rate of the fluid to be filtered.

2. Particle size. The size of the particles to be removed.

3. Viscosity. The viscosity of the fluid.

4. Pressure drop. The allowable pressure drop across the filter element.

5. Backwash frequency. The desired frequency of the backwash process.

 

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.
