Three.Operating Principle How Does It Work
A Twist-Porous Regulating Fiber Filter is an advanced filtration equipment. It utilizes a soft, high-strength curved fiber filament with stable performance and high single-filament strength as the filter material, combined with an electrical control system to process raw water filtration. It boasts high filtration accuracy, large flow rate, and relatively small land occupation.
Twisting pore controll fiber filter is an advanced filter equipment. It USES a kind of stable performance, high strength single filament soft, high strength curved fiber filament as the filter material, with the electronic control system, to achieve the filtering of raw water treatment, which has the advantages of high filtering accuracy, large flow, relatively small cover area.
Unlike traditional vertical filtration methods, this filter allows the pre-filtered water to pass through the filter layer horizontally, enabling devices with the same diameter to achieve higher flow rates and capacities.
Different from the traditional longitudinal flow filtration method, the incoming-water is transversely through the filtration layer, so with the same diameter the equipment can achieve a larger flow velocity and flow rate.
1.Filter StatusFiltering
As shown in the right figure, the rotary mechanism mounted on the outside of the drum drives the filter unit to rotate, causing the PP fiber bundle to tightly wrap around the central water output pipe, forming a uniform, fine, and dense porous filter layer. The filtered water passes through this filter layer from the outside to the central water output pipe, thereby trapping and adsorbing impurities in the water. During the filtration process, the pre-filtered water system passes through the filter layer horizontally because the PP filter fibers are arranged in a certain pattern, thus no bias flow occurs.
As shown in the figure on the right, the rotating units outside the tank drives the filtration module to rotate, so that the PP fiber bundle is tightly wound on the central tube，forming a uniform, tiny and dense porous filtration layer.through which the incoming water enters the central tube from the outside, thereby retaining and adsorbing the sewage in the water. In the process of filtration, the incoming water goes through the filtration layer in a horizontal direction. Because the PP filter wires are arranged in a certain rule, the bias phenomenon will not occur.

A certain quantity of fine PP fiber bundles are wrapped longitudinally around the central drain pipe, forming a filter unit. Depending on the specifications of the filter, one or four filter units are set up inside the tank.
A certain number of fine PP fiber bundles are longitudinally wrapped on the central gathering pipe to form a filter unit. One ｏｒ four sets of filter units are set in the tank according to the size of the filter specifications.
The surface area of the four filter cartridges inside the equipment exceeds the cross-sectional area of the drum, thus allowing for a high theoretical filtration rate of up to 100m/h. Generally, the rate is between 60 to 80m/h. Taking a DN2000 twisted-pore regulating fiber filter as an example, its flow rate can reach 200 to 300 T/H, whereas a standard DN2000 high-efficiency fiber filter typically operates at a flow rate of 30m/h with a corresponding flow of 94 T/H.
The surface area of the four filter cartridge in the equipment is larger than the cross-sectional area of the tank, so its theoretical filtration rate can be up to 100m/h. Generally, it can reach 60 ~ 80m/h. For example, the flow rate of DN2000 torsional pore regulated fiber filter can reach 200 ~ 300T/H, while the conventional flow rate of DN2000 high efficiency fiber filter is 30m/ H, and the corresponding flow rate is 94T/H.
2.Backflush stateBackwashing
When the retained material increases and the pressure difference (or flow, operating time) reaches the set value, the automatic backwashing process is initiated. During backwashing, the external rotating mechanism drives the PP filter fibers to relax completely, under the combined action of backwashing water flow and cleaning air, washing off the retained pollutants and discharging them through the effluent pipeline. After cleaning, the system can automatically switch to the filtering state or standby state.
When withholding content increased, the differential pressure (flow rateor Running time) to set data, automatically enters backwashing steps. The rotating units outside the tank drives the filtration module thoroughly relaxed, under the joint action of the backwashing water and compresses air, the elution of sewage intercepted is discharged through the drainage pipe, after cleaning can automatically enter the filtering state ｏｒ into standby state.
|
|
During the backwashing process, the introduction of cleaning air causes the PP filter fibers to vibrate intensely and rub against each other, along with the effect of the cleaning air, making it easy for the retained materials on the filter fibers to be removed under the combined flushing of backwashing water and cleaning air. Additionally, the rotating mechanism drives the filter fibers to perform several rotations and relaxation actions during the backwashing process, which aids in achieving a better backwashing effect similar to that of a washing machine.
The compressed clean air, make PP fiber bundle in the process of cleaning produce strong jitter and rubbing against each other, and Plus the carrying effect of cleaning air,the sewage intercepted on the fiberbundle can be easily peeled off by the combined washing water and cleaning air. In addition, the rotary mechanism drives the filter wire to repeat several times of rotation and relaxation during the backwashing process, which is helpful to obtain better backwashing effect similar to that of washing machine.
