多柱式自清洗过滤器01

I. Product Introduction

The multi - column self - cleaning filter is an advanced filtration device that integrates multiple filter columns into a unified system, combining high - efficiency filtration with automatic self - cleaning functionality. Each filter column is equipped with high - quality filter media, such as stainless - steel wire mesh, sintered metal filters, or high - performance filter cartridges. These columns work in parallel during normal filtration, significantly increasing the overall filtration area and flow - handling capacity. When the fluid enters the filter, it is evenly distributed among the columns, and impurities like suspended solids, colloids, rust, and sediment are effectively intercepted by the filter media. As the impurities accumulate, and either the pressure difference between the inlet and outlet reaches a preset value (usually 0.05 - 0.1MPa) or the operation time reaches a set duration (e.g., 8 - 24 hours), the self - cleaning system is activated. Through a sophisticated control mechanism, the filter columns are cleaned one by one or in groups without interrupting the overall filtration process, ensuring long - term stable operation and reducing manual maintenance requirements. This makes the multi - column self - cleaning filter highly suitable for industries with high - flow and continuous filtration demands, such as industrial water treatment, petrochemicals, and food processing.

II. Working Process

  1. Normal Filtration Stage

    • Fluid Inflow: The fluid to be filtered enters the main body of the multi - column self - cleaning filter through the inlet. A well - designed distribution system evenly divides the fluid flow among all the filter columns, ensuring that each column bears an appropriate load and operates efficiently.

    • Filtration in Columns: Inside each filter column, the fluid passes through the filter media from the outside to the inside (or vice versa depending on the design). During this process, the filter media traps various impurities, while the purified fluid flows out of the columns and converges towards the outlet of the filter, ready to be transported to the subsequent processes.

  2. Self - Cleaning Trigger

    • Pressure Difference Trigger: As the filtration progresses, impurities gradually accumulate on the filter media within the columns, increasing the flow resistance and causing the pressure difference between the inlet and outlet of the filter to rise. Once this pressure difference reaches the pre - set threshold (0.05 - 0.1MPa), it serves as a signal to start the self - cleaning process.

    • Time - Based Trigger: In cases where the fluid quality is relatively good and the pressure difference does not increase significantly, the filter initiates self - cleaning based on a pre - determined operation time (e.g., 8 - 24 hours). This regular cleaning schedule helps maintain the optimal filtration performance of the columns.

  3. Self - Cleaning Process

    • Isolation of Columns: When the self - cleaning process starts, the control system isolates one or several filter columns from the normal filtration flow. This is achieved by closing specific valves connected to the columns, preventing the fluid from passing through them.

    • Backwashing or Scrubbing: For the isolated columns, different cleaning methods can be applied. In the case of backwashing, a high - velocity reverse flow of clean fluid (either from a dedicated backwash water source or recycled treated water) is introduced into the columns. The reverse flow scours the filter media, loosening and flushing away the accumulated impurities. Some models may also use a scrubbing mechanism, where mechanical brushes or scrapers clean the surface of the filter media to remove stubborn contaminants more effectively.

    • Impurity Discharge: The flushed - out impurities are carried by the cleaning fluid and discharged from the filter through a dedicated 排污口. After the cleaning is completed, the isolated columns are reconnected to the normal filtration flow, and the system proceeds to clean the next set of columns until all columns have been cleaned.

  4. Resumption of Normal Filtration: Once all the filter columns have completed the self - cleaning process, the filter fully resumes its normal filtration operation, ensuring a continuous supply of purified fluid.

III. Product Features

Key AdvantagesDescription
High - Flow and Large - Capacity FiltrationWith multiple filter columns working in parallel, the filter can handle high - flow rates, with a treatment capacity ranging from 10 - 2000m³/h, making it ideal for large - scale industrial applications.
Intelligent Automatic Self - CleaningThe built - in intelligent control system precisely monitors the operation status of each column and triggers self - cleaning based on pressure difference or time. The cleaning process can be adjusted according to actual needs, ensuring efficient and timely maintenance.
Low Maintenance and Long Service LifeThe self - cleaning function significantly reduces the frequency of manual filter media replacement. High - quality materials used for the filter columns and components ensure excellent corrosion resistance and wear resistance, extending the overall service life of the filter to 8 - 10 years.
Flexible Configuration and AdaptabilityDifferent types of filter media can be installed in the columns to meet various filtration precision requirements (ranging from 5 - 3000 microns). The filter can also be customized in terms of the number of columns and connection modes, adapting well to different process requirements and site conditions.
Energy - Saving and Water - Saving DesignThe optimized self - cleaning process minimizes the consumption of cleaning water, with each cleaning cycle consuming only 0.5 - 1% of the treated water volume. The efficient hydraulic design reduces energy loss during normal filtration, lowering overall operating costs.
