Structural Features

The unique-design horizontal self-cleaning filter typically exhibits the following structural characteristics:

1. Horizontal Configuration

The equipment body is horizontally arranged, facilitating a lower profile, space-saving installation, and convenient maintenance.

2. Modular Design

Key components such as filter cylinders, valves, controllers, and backwash pumps are designed modularly, allowing flexible configuration according to actual needs, ease of expansion, or replacement.

3. Precision Filtration Elements

Depending on the nature of the treated liquid and filtration accuracy requirements, different materials and precision grades of filtration elements are selected to ensure effective filtration.

4. High-Strength Housing

Typically made of carbon steel or stainless steel, the housing possesses excellent corrosion resistance and pressure-bearing capability.

5. Intelligent Control System

Integrating pressure difference sensors, time controllers, solenoid valves, PLCs, and other elements, the system achieves automated control over the entire filtration, cleaning, and monitoring processes.

 

Working Principle

The unique-design horizontal self-cleaning filter combines pressure difference control and time-based control to achieve automatic cleaning. The workflow is as follows:

1. Normal Filtration Stage

The incoming liquid enters the filter through the inlet port, first entering the interior of the filter cylinder. The filter cylinder contains precision filtration elements (such as metal mesh, filter cloth, or sintered filter cores), which effectively intercept impurities in the liquid. Clean liquid passes through the filter cylinder and exits via the outlet port, proceeding to the next process or system.

2. Pressure Difference Monitoring and Triggering Cleaning

As the accumulation of impurities on the filter cylinder surface increases during filtration, a pressure difference forms between its inner and outer sides. When this pressure difference reaches a preset value, the control system automatically initiates the cleaning program. A differential pressure sensor continuously monitors and feeds back this change, ensuring precise triggering of the cleaning process.

3. Backwashing Process

During cleaning, the control system closes the inlet valve, opens the drain valve, and activates the internal backwash pump. The backwash pump draws a portion of clean liquid or external water source, directing it in reverse at high pressure through the filter cylinder, forcefully scouring the inner wall to dislodge adhered impurities, which then exit along with the backwash liquid through the drain port. Special designs at the bottom of the filter cylinder (such as an air cushion or scraper) enhance cleaning effectiveness during this process.

4. Cleaning Completion and Resuming Filtration

After backwashing is completed, the drain valve closes, the inlet valve reopens, and the filter resumes normal filtration mode. The entire process requires no manual intervention, achieving full automation.

 

Application Areas

The unique-design horizontal self-cleaning filter, due to its efficiency, intelligence, and user-friendly operation, finds widespread use in the following fields:

1. Industrial Production

Such as chemical, pharmaceutical, food & beverage, metallurgy, power generation, oil & gas industries, in applications involving process water, circulating cooling water, wastewater treatment, and more.

2. Environmental Treatment

In wastewater treatment plants for pretreatment, reclaimed water reuse, and advanced treatment stages, as well as in rainwater harvesting, surface water purification projects, and others.

3. Water Treatment

In waterworks, drinking water equipment, pool water treatment, seawater desalination pretreatment, and so forth.

4. Agricultural Irrigation

For agricultural irrigation water, greenhouse fertigation systems, aquaculture water treatment, among others.

 

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.
