.概述Abstract


孔隙調節型纖維過濾器(PORE CONTROLLABLE  FIBER BUNDLE FILTER),又可稱為扭轉式纖維過濾器(TWISTING FILTER)。是一種利用經過特殊處理的長纖維為過濾介質的水過濾設備。針對傳統的纖維過濾設備過濾面積相對較小的缺點,該設備采用橫向流過濾方式,在不加大設備直徑的前提下有效地增加了過濾面積,提高了設備流量。上世紀九十年代國內率先有人提出扭轉式纖維過濾器的構思并加以實施。本公司在總結改善前人的技術基礎上,申請了相關的專利并獲得了授權。

    Pore Controllable Fiber Bundle Filter, also can be referred to as TWISTING FIBER FILTER. The water filtration equipment which using a specially treated long fiber as the filtration medium. In view of the disadvantage of relatively small filtration area of traditional fiber filtration equipment, this equipment adopts the transverse flow filtration mode, which effectively increases the filtration area and increases the flow rate of the equipment without increasing the diameter of the equipment. In 1990s, the concept of twisting fiber filter was firstly put forward and implemented in China. On the basis of summarizing and improving previous technologies, our company has applied for relevant patents and obtained authorization.

 

 

.工作原理 How Does It Work

 

 

      扭轉式孔隙調節型纖維過濾器是一種先進的過濾設備。它采用一種性能穩定、單絲強度高的柔軟、高強曲化纖維長絲作為濾材,配合電控系統,實現對原水的過濾處理,其具有過濾精度高、流量大、占地面積相對小等優點。

 

      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.

 

       不同于傳統的縱向過濾方式,這種過濾器濾前水是橫向穿過濾層的,所以同樣直徑的設備,能夠實現較大的流速和流量。

 

       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.過濾狀態Filtering

 

 

 

    如右圖中所示,設置在罐體外部的回轉機構驅動過濾單元旋轉,使PP絲束緊密纏繞在中心產水管上,形成均勻、微小、致密孔隙的過濾層。待濾水從外部通過該濾層進入中心產水管,從而對水中的污物起到截留和吸附作用。在過濾過程中,濾前水系沿水平方向穿過濾層,因為PP濾絲是按一定規律排列,所以不會產生偏流現象。

 

    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.

 

 

 

 

   “一定數量的柔細的PP纖維束沿縱向包裹在中心集水管上,構成一個過濾單元。根據過濾器規格大小的不同,在罐體內設置一套或四套過濾單元。”

 

     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.

 

   設備內四處濾筒的表面積大于罐體的橫截面積,因此其理論濾速最高可到100m/h。一般可達60~80m/h。以DN2000的扭轉式孔隙調節型纖維過濾器為例,其流量可達到200~300T/H,而普通的DN2000的高效纖維過濾器其常規流速為30m/h,相應的流量為94T/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.逆洗狀態Backwashing

 

 

 

    當截留物增多,壓差(或流量、運行時間)達到設定值時,即自動進入反洗步驟。反洗時,外部的回轉機構驅動PP濾絲徹底放松,在反洗水流和清洗空氣的聯合作用下,把截留的污物洗脫并通過排污管路排出,清洗結束后可自動進入過濾狀態或進入待機狀態。

 

    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.

 

 

 

      反洗時因為引入了清洗空氣,使PP濾絲在清洗過程中產生強烈的抖動并相互摩擦,加之清洗空氣的攜帶效應,使濾絲上的截留物很容易在反洗水流和清洗空氣的聯合沖刷下剝離下來。另外回轉機構在反洗過程中驅動濾絲重復若干次回轉和放松動作,有助于獲得類似洗衣機的更好的反洗效果。

 

    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.

.設備維護保養注意事項Equipment Maintenance Notes

1.使用注意事項Operational Considerations

 

  1)設定反沖洗壓力(0.5-0.8㎏/㎝2)時,不要設定過高,否則會造成過濾水質惡化,水量減少,排管異常等。

 

   Set back flush pressure (0.5-0.8㎏/㎝2), don't set too high,or will cause deterioration of water quality, water flow reduction and abnormal exhaust pipe, etc.

 

   2)原水進水口裝調節閥和止回閥;反沖洗進水口裝止回閥。

Install regulating valve and check valve at raw water inlet; install check valve at backflush inlet.

 

   3)運行狀態下嚴禁往回轉齒輪處伸手或放入其他物體等。

It is strictly prohibited to reach for or put other objects into the rotary gear under the running state.

 

   4)停機后一定要反復沖洗過濾纖維,徹底排除過濾器內部的水(使過濾纖維絲不粘有懸浮物,如沒有沖洗干凈,則會降低過濾效果)。

   After the filter is shut down, it is necessary to repeatedly flush the filter fiber, and completely remove the water inside the filter (making filter fiber filaments free of suspended solids; if not, the filtering effect is reduced)

 

   5)一個月至少進行藥劑浸泡清洗一次,用CaCLO2或NaCLO等消毒劑(CL的濃度為20ppm)注入過濾器內浸泡至少12個小時左右,進行氣、水混合沖洗清除濾材纖維絲上的藻類和微生物等物質。

   Soak and clean at least once a month. Infuse disinfectant such as CaCLO2 or NaCLO (CL concentration is 20ppm) into the filter and soak for at least 12 hours. Then mix air and water to rinse and remove algae, microorganisms and other substances on the filter fiber.

 

   6)建議三個月一次拆下所有閥門,用軟布徹底清除其內異物。

   It is recommended to remove all the valves once every three months and thoroughly remove the foreign bodies with soft cloth.

 

   7)為防止回轉齒輪生銹,需定期涂抹潤滑脂。

   To prevent rotary gear from rusting, grease should be applied regularly.
