200422582 玖、發明說明： 一、發明所屬之技術領域_ 本發明係關於一種淸除系統，其使用可移動淸洗元件用 來淸洗管路內側。 —n先前技術 熱分配系統一般具有凝結器單元，其包含有傳送流體的 配管。過去以來已提案有許多淸洗此管路內側的方式，以 防止流體流過管路之時，在管路內側累積髒物或其它非所 要沉積物。 一個提出之方法係使用由橡膠或海綿狀材料製成的淸洗 球’其直徑稍比管路者更大，使得當其等隨流體而移動通 過管路之時，球會被壓縮。以此方式，球會被迫擦過管路 之壁，以保持壁淸潔且免除沉積物。通常，球及流體係從 上游側朝流體流動方向而通過管路流到管路之下游側。然 後球在下游側從流體分離，然後再循環回到管路之上游 側。如美國專利US6,070,652號專利文件中所揭示之一個 栗，一般設置有將球再循環的裝置。但是，使用栗將球再 循ί哀的一個缺點在於’栗易產生誤動作，並且此系統通常 需要相當的停機時間以供維修。 爲了克服上述缺點，已有提案一種淸除系統，其不需要 使用泵將球再循環，其一個例子係揭示於美國專利u S 5， 5 9 2，9 9 0號專利文件中。在該先前技術中，再循環裝置包括 有一個外殻設置於管路之上游與下游側之間。外殻包括一 個穿孔的隔板，其可將外殻區分成上室及下室。當球再循 環且被此外殻收集之時，隔板可使流體通過下室，而保持 200422582 球在上室中。外殼另外包括有··第1通道，其連接上室的 一端到管路之下游，第2及第3通道，其連接上室的另一 端到管路上游側之第1及第2段，使管路之第2段的壓力 在與第1段的壓力比較時稍低，但是比管路之下游側者更 高。外殼亦包括有第4通道，其連接下室到一個壓力比其 它三個通道之任何一個之壓力低之來源。在此先前技術中 所揭示的淸除系統亦具有複數個閥，其配置用來控制沿著 上述不同通道中之流體流動。此先前技術之一個缺點爲設 計之複雜度，其需要一個序列之動作用來打開及關閉複數 個閥，以將球再循環。除此之外，爲了將球拉入外殼中， 設置於第4通道的閥必須打開，因而可能會使流體排出。 因此，每次球被再循環時均會浪費流體，並且維護此系統 的成本可能很昂貴。 本發明之一個目的在提供一種淸除系統，其可消除先前 技術之至少一個缺點。 三、發明內容 本發明，依照其一般定義，在提供一個淸洗連到入口管 及出口管的管路，其使用如淸洗球之淸洗元件，其可由控 制兩個閥之打開及關閉而再循環。 本發明之第1目的在提供一種用來淸洗傳送流體用之管 路的系統，管路係被連到入口管及出口管，該系統具有·· 複數個淸洗球，其可隨著通過管路的流體而循環； 一個設置於出口管且配置成將淸洗球從流體分離的分離 器； 一個再循環裝置，其包括有： 200422582 一個外殼，配置成可收集淸洗球，該外殼具有由一 個有穿孔的隔板所分隔之第1及第2室，穿孔的隔板 配置成可使流體而非淸洗球通過第2室； 一個球輸送管，其具有一個入口連結到外殼之第1 室上的第1開口，及一個出口連結到入口管上的第1 開口； 一個流體輸送管，其具有一個入口連結到入口管上 之第2開口，及一個出口連結到外殻之第1室上的第2 開口； 一個流體送回管，其具有一個入口連結到外殼之第2 室上的一個開口，及一個出口連結到出口管上的開 P ； 一個球送回管，其具有一個入口連結到在分離器上 之開口，及一個出口連結到外殼之第1室上的第3開 □； 一個裝置，用來輸送淸洗球到入口管，因而使高壓可形 成於流體輸送管的入口，並且低壓可形成於球輸送管之出 口，壓力差造成淸洗球從外殼轉移到入口管；及 一個裝置，用來將淸洗球回歸到外殼，而使高壓形成於 球送回管之入口，並且低壓可形成於流體送回管的出口， 壓力差造成淸洗球從分離器轉移回到外殻， 其中，再循環裝置、輸送淸洗元件的裝置及將淸洗球送 回的裝置被配置成，可選擇地將複數個淸洗球從入口管轉 移到出口管。 最好，淸除系統中之再循環裝置又包括有第1閥沿著流 2004225 82 體輸送管而設置’第2閥沿著流體送回管而設置，第丨單 向閥沿著球輸送管而設置，及第2單向閥沿著球送回管而 設置；第1單向閥被操作時可將淸洗元件從外殻轉移到入 口管，並且第2單向閥被操作時可將淸洗球從分離器轉移 到外殻。 ’ 最好，淸除系統中之再循環裝置又包括一第3閥沿着球 送回管而設置及一第4閥沿著球輸送管而設置。 最好，淸除系統中之淸洗球供應裝置係由打開第1閥且 保持第2閥關閉而操作，其可在流體輸送管之入口處造成 高壓，並且在球輸送管之出口造成低壓，高壓形成一個吸 力將流體從入口管通過流體輸送管而吸入外殼，流過外殼 之流體的力量將淸洗球從外殼通過第1單向閥而移動到球 輸送管，其中第4閥保持打開，造成淸洗球流入入口通道 中。 最好，將淸除系統中之淸洗球送回的裝置係由打開第2 閥且保持第1閥關閉而操作，因而在球送回管之入口處造 成高壓，且在流體送回管之出口處造成低壓，高壓形成一 個吸力將流體及淸洗球從分離器通過第2單向閥而吸入球 送回管，流體的力量將淸洗球通過第2單向閥而移動到球 送回管而進入外殻，其中該淸洗球被扣住於外殻中，而流 體流經外殼中之穿孔隔板而回到第2閥保持打開的流體送 回管，並且進入出口通道中。 最好，淸除系統具有漏斗狀之分離器。 最好，淸除系統之分離器包括有穿孔，其可使流體穿過 但是不使淸洗球通過。 200422582 最好’分離益之穿孔爲矩形長孔、每一個具有長度方向 之形式。 最好，分離器之矩形長孔的長度方向並不平行於漏斗的 中心軸。 最好，淸除系統具有第1裝置，其可轉動在管路之前的 入口管處之流體及淸洗球，以使淸洗球散亂分佈地進入管 路中。 最好，淸除系統具有第2裝置，其可轉動在分離器之前 的出口管處之流體及淸洗球，以使淸洗球在通過管路時累 積於其表面的髒物從淸洗球表面鬆動，並且在流體中被帶 離。 最好，轉動流體及淸洗球的裝置之方向係對向於矩形長 孔的長度方向。 本發明上述實施例之一個優點爲在入口管及出口管處之 不同壓力造成吸力，其可提供簡單且成本低廉的方法將淸 洗管路之淸洗球循環。此一個系統亦對環境友善，因爲沒 有浪費流體。 本發明尤其在淸洗熱交換器或凝結器之流體傳送管路時 特別有用’並且本發明在下面因而係以此應用而說明。 四、實施方式 第1圖係顯示用來淸洗一個凝結器7之中的管路8的淸 除系統。管路8係複數個平行且相隔開的管子，其等被連 到一個入口管5及一個出口管9。一種如水之冷卻流體通 過管路8 ’以使其它如蒸汽或冷凍氣體之流體凝結，該流 體從入口 25循環通過在管路8與一個出口 29之間的空間。 200422582 冷卻流體（朝向w 1所示之方向）從一個入口通道丨循環通 過凝結器管路8而到出口通道1 5，入口通道1由入口管5 而連到凝結器之上游側，而出口通道1 5則由出口管9而連 到管路8之下游側。 淸除系統包括有複數個淸洗元件，並且在此實施例中係 使用淸洗球20。此淸洗球20 —般係由海綿狀材料製成，並 且其直徑稍比管路8之直徑更大，因而當淸洗球20被強迫 通過管路8之時會被壓縮，以防止微粒在管路8中堆積。 依此方式，可防止管路8中累積不必要的沉積物，以免降 低熱交換器的效率或甚而造成腐蝕。 淸除系統又包括一個分離器1 2及再循環裝置，其可將淸 洗球20從出口管9轉移到入口管5。 分離器1 2之功能在將淸洗球2 0從在出口管9處的冷卻 流體中分離，並且在此實施例中，分離器1 2爲漏斗狀。分 離器1 2插入於出口管9與排掉流體的出口通道1 5之間。 分離器1 2包括有穿孔，其配置成使流體通過流到出口通道 15，但是不讓淸洗球20通過。 最好，穿孔爲矩形長孔3 2之形式，其具有長度方向傾斜 於特定方向，例如從流體流動方向看時爲反時針方向。本 實施例之分離器1 2及矩形長孔32的詳圖分別顯示於第5 及6圖中。分離器1 2被連到再循環裝置，以將淸洗球20 從出口管9轉移到入口管5。 在此實施例中，再循環裝置包括一個收集淸洗球20用之 外殻2 1。外殻2 1具有穿孔之隔板2 8，其將外殼2 1區分成 第1室1 9及在隔板2 8之對向側的第2室2 7。隔板2 8可使 -10- 200422582 流體通過，但是不讓淸洗球2 0通過，因而淸洗球2 0累積 於第1室19中。外殻21又包含一個蓋子18用以蓋住第1 室1 9，並且可移除，以便加入或移除淸洗球20。 再循環裝置又包括有一個流體送回管16及球送回管 1 7。流體送回管1 6用來連接外殼2 1到出口通道1 5，以將 流體（而非淸洗球2 0)從外殻2 1轉移到出口通道1 5。流體送 回管16在外殼21之第2室27上具有一個入口 30,並且在 出口通道15上有一個出口 14。球送回管17用來連接分離 器1 2到外殼2 1，以從出口管9轉移淸洗球20到外殼21。 球送回管17在分離器12上具有入口 13，並且在外殼21 之第1室19上具有出口 31。球送回管17之進入開口 13 係形成於抵擋出口管9之流體流動W 3的方向上，使球送 回管17之入口 13處的壓力高於在流體送回管16之出口 14 處的壓力。球送回管17可包含有一個手動閥HV2，除了當 更換或加入淸洗球20之外，其係永遠打開。 再循環裝置亦包括有一個球輸送管24及一個流體輸送管 23。球輸送管24係用來連接外殻2 1到入口管5，以從外殼 2 1輸送淸洗球2 0回到入口管5。 球輸送管24在外殻21之第1室19上具有入口 26,並且 在入口管5具有出口 3。球輸送管24可包含有一個手動閥 ΗV 1 ’除了當更換淸洗球2〇之外，其係永遠打開。流體輸 送管2 3係用來連接入口管5到外殻2丨，以將流體從入口管 5轉移到外殻21。流體輸送管23在入口管5具有具有入口 2，並且在外殼21之第1室19上具有出口 22。流體輸送管 23之入口 2係形成於抵擋入口管5之流體流動W 1的方向 -11 - 2004225 82 上，使流體輸送管23之入口 2處的壓力高於在球輸送管24 之出口 3處的壓力。 輸送淸洗球的裝置及送回淸洗球的裝置包括兩個閥V 1 及V2,其分別沿著流體輸送管23及流體送回管16而設置， 以控制淸洗球20從凝結器管路8之下游側流經外殼2 1而 到凝結器管路8之上游側。輸送淸洗球20的裝置係由打開 第1閥V 1且保持第2閥V2關閉而操作，以使淸洗球20 從外殻2 1被吸到入口管5。送回淸洗球20的裝置係由打開 第2閥V2且保持第1閥V1關閉而操作，因而淸洗球20 從分離器1 2被吸回到外殼2 1。 外殼21亦包括有兩個逆止閥或單向閥CV1及CV2，分別 沿著球輸送管24及球送回管17而設置。第1逆止閥CV1 僅可使流體及淸洗球20從外殼2 1到入口管5的方向流動， 反之不可。第2逆止閥CV2僅可使流體及淸洗球20從分離 器1 2到外殻2 1的方向流動，反之不可。 淸除系統又包括轉動裝置配置於入口管5及出口管9 處，並且在此實施例中係使用螺旋槳。 第1螺旋槳4被設置在入口管5且在管路8之前，用以 轉動淸洗球20，使淸洗球20以如符號6所指示之散亂形式 進入管路8中。轉動裝置在確保淸洗球20在進入凝結器7 時可由離心力而散亂地分佈。第2螺旋槳1 0被設置於出口 管9處且在分離器1 2之前，其可轉動流體及淸洗球20，使 淸洗球2 0彼此在分離器1 2之之開口 1 1處碰撞。此可提高 在淸洗球2 0之間的碰撞次數，以在淸洗球2 0通過管路8 之後，移除堆積在淸洗球20表面上的髒物。 -12- 200422582 在敘述淸除系統之許多元件之後，將參照第1,2,3及4圖 而說明淸除系統的操作。 吾等假設一個初期位置，其顯示於第1圖中，藉此使閥 VI及V2被關閉，並且淸洗球20被堆積於外殼21之第1 室1 9中。在球輸送管24及球送回管1 7中沒有流體流動， 因爲在球輸送管24之出口 3處的壓力係高於在球送回管17 之入口 13處的壓力，以及兩個逆止閥CV1，CV2的功用之 故。 當凝結器7操作時，冷卻流體通過入口管5。依照流體力 學的原理，在流體輸送管23之入口 2處的靜壓係高於在球 輸送管24之出口 3處的靜壓，因爲流體輸送管23之入口 2 係形成於抵擋入口管5之流體流動W1的方向上。此壓力 差形成一個吸力，其可將流體從入口管5經由流體輸送管 23而吸入到外殼2 1，並且將流體及淸洗球20從外殻2 1經 由球輸送管24吸入到入口管5。 爲了使淸洗球20從外殻2 1被吸出到入口管5，第1閥 V 1被打開而第2閥V2被關閉，使流體可從入口管5被吸 入到外殻2 1，並且然後淸洗球20從外殻2 1被吸出而進入 入口管5以循環到管路8而淸洗管路8的內壁。這是顯示 於第2圖之情形。流體從流體輸送管23流入外殼2 1的方 向，以及淸洗球20從外殼2 1經由逆止閥CV 1流動的方向 係顯示於第2圖的粗箭頭中。 輸出淸洗球20而產生淸洗球20之轉移的裝置係由打開 第1閥V 1且保持第2閥V 2關閉而操作。依此方式，淸洗 球20根據流體輸送管23之入口 2與球輸送管24之出口 3 -13- 200422582 的壓力差而從外殼2 1被吸到管路8之上游。 在所有的淸洗球2 0被吸到入口管5之後，第1閥V1被 關閉且第2閥V2保持關閉。當第1閥V1被關閉時，淸洗 球20的輸送被停止，如第3圖所示。 當第1閥V1被打開時，第1螺旋槳4亦被作動，以迫使 流體流動W2及淸洗球20轉動，因而淸洗球20散亂地進入 管路8中。 在淸洗過程之後，第2螺旋槳1 0再度轉動淸洗球20，使 淸洗球20彼此碰撞，並且被淸洗球20從管路8移除且目 前附著於淸洗球2 0的污物微粒被擦除。然後，污物微粒被 流體流動W3所攜帶而經由出口通道1 5排出。須提及者， 第2螺旋槳1 0及從而淸洗球2 0之轉動方向最好爲與分離 器1 2之傾斜長孔3 2之方向爲對向。例如，若傾斜長孔3 2 之長度方向爲反時針方向時，則淸洗球2 0被螺旋槳1 〇所 轉動的方向最好爲順時針方向。此可提高淸洗球20彼此之 間的碰撞次數。 在轉動之後，淸洗球20累積在分離器1 2之開口 1 1上， 如第3圖所不。 依照流體力學的原理，在球送回管1 7之入口 1 3處的靜 壓係高於在流體送回管1 6之出口 1 4處的靜壓，因爲球送 回管1 7之入口 1 3係形成於抵擋出口管9之流體流動W3 . 的方向上。此壓力差形成一個吸力，其可將流體（及淸洗球 20)從分離器12經由球送回管17而吸入到外殻2卜並且將 流體（非淸洗球20 ’由於外殼21之穿孔隔板28)從外殼21 經由流體送回管1 6吸入到出口通道1 5。 -14- 200422582 將淸洗球20從分離器1 2送回到外殼2 1的裝置，係由打 開第2閥V 2且保持第1閥V1關閉而操作，因而淸洗球20 從分離器1 2被吸回到外殼2 1，並且流體（非淸洗球20，由 於外殼21之穿孔隔板28)從外殼21被吸到出口通道15。 這是顯示於第4圖之情形。流體及淸洗球20從球送回管1 7 流入外殼2 1的方向，以及流體從第1室1 9進入第2室2 7 然後進入流體送回管1 6的流動方向係顯示於粗箭頭中。 最後，當所有的淸洗球20已回到外殼21之第1室19且 堆積在此之時，閥V1及V2均關閉，如第1圖所示。當閥 V2關閉時，淸洗球20之送回操作被停止。 可了解，將淸洗球20送回的裝置，係由打開第2閥V2 且保持第1閥V 1關閉而操作。而輸送淸洗球20的裝置係 由打開第1閥V 1且保持第2閥V2關閉而操作。在兩個操 作中，淸洗球20均由淸洗球送回裝置的操作，及輸送淸洗 球裝置之操作而循環通過再循環裝置。在兩個操作中，係 由兩個閥V 1及V2之打開及關閉、或關閉及打開，而在球 送回管17之入口 13與流體送回管16之出口 14之間，以 及在流體輸送管23之入口 2與球輸送管24之出口 3之間 造成壓力差。因此，整個淸除系統之操作可以經由兩個手 工或機械操作的閥V 1及V2而很容易地控制。 當需求產生時，當淸洗球20必須更換時，手動閥ΗV 1， HV2被關閉，並且蓋18被打開，使淸洗球20可被更換。 雖然本發明在此已參照較佳實施例而說明，須了解，在 不違離本發明隨附之申請專利範圍所定義的範疇之下，熟 於此技術者可從事許多變更及應用或修改。 -15- 200422582 本發明之有利效果 從上述實施例中可看出，整個淸除系統之操作可以經由 兩個閥VI及V2而很容易地控制，閥VI及V2可爲手工操 作或設置裝置以自動地操作。並且，整個淸除系統具有限 的移動零件，因而更可靠且需要更少的維修。 除此之外’淸除系統並不浪費冷卻流體，其可隨著淸洗 球20而一起再循環。 五、圖式簡單說明200422582 Description of the invention: 1. Technical field to which the invention belongs _ The present invention relates to a cleaning system that uses a movable cleaning element to clean the inside of a pipeline. —N Prior art Heat distribution systems typically have a condenser unit that contains piping to convey fluid. Many ways have been proposed in the past to wash the inside of this pipe to prevent dirt or other unwanted deposits from accumulating inside the pipe when fluid flows through it. One proposed method uses a wash ball made of rubber or sponge-like material, which is slightly larger in diameter than the pipe, so that when the ball moves with the fluid through the pipe, the ball is compressed. In this way, the ball will be forced across the wall of the pipe to keep the walls clean and free of deposits. Generally, the ball and flow system flows from the upstream side toward the fluid flow direction through the pipeline to the downstream side of the pipeline. The ball is then separated from the fluid on the downstream side and recirculated back to the upstream side of the pipe. A pump, such as that disclosed in U.S. Patent No. 6,070,652, is generally provided with a device for recirculating the balls. However, one disadvantage of using a chestnut to re-ball is that the chestnut is prone to malfunction, and this system usually requires considerable downtime for maintenance. In order to overcome the above disadvantages, an eradication system has been proposed, which does not require the use of a pump to recirculate the ball. An example of this is disclosed in U.S. Patent No. 5,925,990. In this prior art, the recirculation device includes a casing provided between the upstream and downstream sides of the pipe. The enclosure includes a perforated partition that divides the enclosure into an upper chamber and a lower chamber. When the ball recirculates and is collected by this shell, the baffle allows fluid to pass through the lower chamber, keeping the 200422582 ball in the upper chamber. The housing additionally includes a first passage, which connects one end of the upper chamber to the downstream of the pipeline, and second and third passages, which connect the other end of the upper chamber to the first and second segments on the upstream side of the pipeline, so that The pressure in the second stage of the pipeline is slightly lower than the pressure in the first stage, but it is higher than that on the downstream side of the pipeline. The enclosure also includes a fourth channel that connects the lower chamber to a source with a lower pressure than any of the other three channels. The scavenging system disclosed in this prior art also has a plurality of valves which are configured to control the flow of fluid along the different channels mentioned above. One disadvantage of this prior art is the complexity of the design, which requires a sequence of actions to open and close multiple valves to recirculate the ball. In addition, in order to pull the ball into the housing, the valve provided in the fourth passage must be opened, and thus the fluid may be discharged. As a result, fluid is wasted each time the ball is recirculated and the cost of maintaining this system can be expensive. It is an object of the present invention to provide an eradication system which can eliminate at least one disadvantage of the prior art. 3. Summary of the Invention The present invention, in accordance with its general definition, provides a rinsing pipeline connected to the inlet pipe and the outlet pipe, which uses a rinsing element such as a rinsing ball, which can be controlled by opening and closing two valves. Recycling. A first object of the present invention is to provide a system for rinsing a pipeline for conveying a fluid. The piping system is connected to an inlet pipe and an outlet pipe. The system has a plurality of rinsing balls, which can be passed along with Fluid circulating through the pipeline; a separator provided at the outlet pipe and configured to separate the washing ball from the fluid; a recirculation device comprising: 200422582 a housing configured to collect the washing ball, the housing having The first and second compartments are separated by a perforated partition. The perforated partitions are configured to allow fluids to pass through the second compartment instead of washing balls; a ball duct having an inlet connected to the first 1 opening in chamber 1, and a first opening with an outlet connected to the inlet tube; a fluid delivery tube having a second opening with an inlet connected to the inlet tube, and a first outlet with an outlet connected to the housing A second opening in the chamber; a fluid return pipe having an opening in the second chamber with an inlet connected to the housing, and an opening P connected to the outlet pipe in an outlet; a ball return pipe having a Entrance To the opening in the separator, and a third opening connected to the first chamber of the housing with an outlet; a device for conveying the washing ball to the inlet pipe, so that high pressure can be formed at the inlet of the fluid delivery pipe And the low pressure can be formed at the outlet of the ball conveying pipe, the pressure difference causes the washing ball to be transferred from the shell to the inlet pipe; and a device for returning the washing ball to the shell, so that the high pressure is formed at the entrance of the ball return pipe And the low pressure can be formed at the outlet of the fluid return pipe. The pressure difference causes the scrubbing balls to be transferred from the separator back to the casing. Among them, the recirculation device, the device for transporting the scrubbing element and the device for returning the scrubbing ball are It is configured to selectively transfer a plurality of rinse balls from the inlet tube to the outlet tube. Preferably, the recirculation device in the removal system further includes a first valve provided along the flow 2004225 82 body delivery pipe, a second valve provided along the fluid return pipe, and a one-way valve along the ball delivery pipe. And the second check valve is set along the ball return pipe; when the first check valve is operated, the cleaning element can be transferred from the housing to the inlet pipe, and when the second check valve is operated, the淸 Wash balls are transferred from the separator to the housing. Preferably, the recirculation device in the depletion system further includes a third valve disposed along the ball return pipe and a fourth valve disposed along the ball conveying pipe. Preferably, the cleaning ball supply device in the cleaning system is operated by opening the first valve and keeping the second valve closed, which can cause high pressure at the inlet of the fluid transfer pipe and low pressure at the outlet of the ball transfer pipe. The high pressure creates a suction that draws fluid from the inlet pipe through the fluid delivery pipe into the housing, and the force of the fluid flowing through the housing moves the scrub ball from the housing to the ball delivery pipe through the first check valve, where the fourth valve remains open, Causes scouring balls to flow into the entrance channel. Preferably, the device for returning the cleaning ball in the depletion system is operated by opening the second valve and keeping the first valve closed, thereby causing high pressure at the inlet of the ball return pipe, and at the fluid return pipe. The outlet creates a low pressure. The high pressure creates a suction to suck the fluid and the scrubbing ball from the separator through the second check valve and suck the ball back to the pipe. The force of the fluid moves the scrubbing ball to the ball and returns it through the second check valve. The tube enters the casing, and the rinsing ball is locked in the casing, and the fluid flows through the perforated partition in the casing and returns to the fluid return tube, which is kept open by the second valve, and enters the outlet channel. Preferably, the removal system has a funnel-shaped separator. Preferably, the separator of the depletion system includes a perforation that allows fluid to pass through but does not pass the decontamination ball. 200422582 The best perforation benefits are rectangular long holes, each of which has a lengthwise form. Preferably, the longitudinal direction of the rectangular long hole of the separator is not parallel to the central axis of the funnel. Preferably, the depletion system has a first device which can rotate the fluid and the decontamination balls at the inlet pipe before the pipeline to disperse the decontamination balls into the pipeline. Preferably, the decontamination system has a second device that can rotate the fluid and the decontamination ball at the outlet pipe in front of the separator, so that the dirt accumulated on the surface of the decontamination ball as it passes through the pipeline is removed from the decontamination ball. The surface is loose and is carried away in the fluid. Preferably, the direction of the means for rotating the fluid and washing the balls is opposite to the longitudinal direction of the rectangular long hole. One of the advantages of the above embodiments of the present invention is that the suction pressure caused by the different pressures at the inlet pipe and the outlet pipe can provide a simple and low-cost method to cycle the washing balls of the washing pipe. This system is also environmentally friendly because no fluid is wasted. The present invention is particularly useful when cleaning fluid transfer lines of heat exchangers or condensers' and the present invention will therefore be described below for this application. 4. Embodiments Fig. 1 shows a cleaning system for cleaning the pipeline 8 in a condenser 7. The pipeline 8 is a plurality of parallel and spaced pipes, which are connected to an inlet pipe 5 and an outlet pipe 9. A cooling fluid, such as water, passes through the conduit 8 'to condense other fluids, such as steam or refrigerated gas, which circulates from the inlet 25 through the space between the conduit 8 and an outlet 29. 200422582 Cooling fluid (in the direction shown by w 1) circulates from an inlet channel 丨 through condenser tube 8 to outlet channel 15; inlet channel 1 is connected to the upstream side of the condenser by inlet tube 5 and the outlet channel 15 is connected to the downstream side of the pipeline 8 by the outlet pipe 9. The erasing system includes a plurality of scouring elements, and a scouring ball 20 is used in this embodiment. The washing ball 20 is generally made of a sponge-like material, and its diameter is slightly larger than the diameter of the pipe 8. Therefore, when the washing ball 20 is forced through the pipe 8, it will be compressed to prevent particles from Accumulation in line 8. In this way, it is possible to prevent unnecessary deposits from accumulating in the pipe 8 so as to avoid reducing the efficiency of the heat exchanger or even causing corrosion. The scavenging system further includes a separator 12 and a recirculation device, which can transfer the scouring ball 20 from the outlet pipe 9 to the inlet pipe 5. The function of the separator 12 is to separate the washing ball 20 from the cooling fluid at the outlet pipe 9, and in this embodiment, the separator 12 is funnel-shaped. The separator 12 is inserted between the outlet pipe 9 and the outlet passage 15 for draining the fluid. The separator 12 includes perforations that are configured to allow fluid to flow through to the outlet passage 15 but not to allow the scrub ball 20 to pass. Preferably, the perforation is in the form of a rectangular long hole 32 having a longitudinal direction inclined to a specific direction, for example, counterclockwise when viewed from the direction of fluid flow. The detailed views of the separator 12 and the rectangular long hole 32 of this embodiment are shown in Figs. 5 and 6, respectively. The separator 12 is connected to a recirculation device to transfer the scrub ball 20 from the outlet pipe 9 to the inlet pipe 5. In this embodiment, the recycling device includes a housing 21 for collecting and washing balls 20. The housing 21 has a perforated partition 28, which divides the housing 21 into a first chamber 19 and a second chamber 27 on the opposite side of the partition 28. The partition plate 28 can pass the -10- 200422582 fluid, but does not allow the washing balls 20 to pass, so the washing balls 20 are accumulated in the first chamber 19. The housing 21 further includes a cover 18 for covering the first chamber 19, and is removable for adding or removing the washing ball 20. The recirculation device further includes a fluid return pipe 16 and a ball return pipe 17. The fluid return pipe 16 is used to connect the housing 21 to the outlet channel 15 to transfer the fluid (not the washing ball 20) from the housing 21 to the outlet channel 15. The fluid return pipe 16 has an inlet 30 in the second chamber 27 of the casing 21 and an outlet 14 in the outlet passage 15. The ball return pipe 17 is used to connect the separator 12 to the housing 21 to transfer the washing ball 20 from the outlet pipe 9 to the housing 21. The ball return tube 17 has an inlet 13 on the separator 12 and an outlet 31 on the first chamber 19 of the casing 21. The inlet opening 13 of the ball return pipe 17 is formed in a direction that resists the fluid flow W 3 of the outlet pipe 9, so that the pressure at the inlet 13 of the ball return pipe 17 is higher than that at the outlet 14 of the fluid return pipe 16. pressure. The ball return tube 17 may include a manual valve HV2, which is always open except when the ball 20 is replaced or added. The recirculation device also includes a ball transfer pipe 24 and a fluid transfer pipe 23. The ball conveying pipe 24 is used to connect the housing 21 to the inlet pipe 5 to convey the washing balls 20 from the housing 21 back to the inlet pipe 5. The ball transfer pipe 24 has an inlet 26 in the first chamber 19 of the housing 21, and has an outlet 3 in the inlet pipe 5. The ball delivery tube 24 may include a manual valve ΗV 1 ′ except that when the 淸 wash ball 2 is replaced, it is always open. The fluid transfer pipe 23 is used to connect the inlet pipe 5 to the housing 2 to transfer fluid from the inlet pipe 5 to the housing 21. The fluid transfer pipe 23 has an inlet 2 in the inlet pipe 5 and an outlet 22 in the first chamber 19 of the casing 21. The inlet 2 of the fluid conveying pipe 23 is formed in the direction -11-2004225 82 which resists the fluid flow W 1 of the inlet pipe 5 so that the pressure at the inlet 2 of the fluid conveying pipe 23 is higher than the outlet 3 of the ball conveying pipe 24 pressure. The device for conveying and washing the ball includes two valves V1 and V2, which are respectively arranged along the fluid conveying pipe 23 and the fluid returning pipe 16 to control the washing ball 20 from the condenser tube. The downstream side of the path 8 flows through the casing 21 to the upstream side of the condenser pipe 8. The device for conveying the washing ball 20 is operated by opening the first valve V 1 and keeping the second valve V2 closed, so that the washing ball 20 is sucked from the housing 21 to the inlet pipe 5. The device for returning the washing ball 20 is operated by opening the second valve V2 and keeping the first valve V1 closed, so the washing ball 20 is sucked back from the separator 12 to the housing 21. The housing 21 also includes two check valves or check valves CV1 and CV2, which are provided along the ball conveying pipe 24 and the ball return pipe 17, respectively. The first check valve CV1 can only flow the fluid and the washing ball 20 from the housing 21 to the inlet pipe 5, and vice versa. The second check valve CV2 can only flow the fluid and the washing ball 20 from the separator 12 to the housing 21, and vice versa. The eradication system further includes a rotating device arranged at the inlet pipe 5 and the outlet pipe 9, and a propeller is used in this embodiment. The first propeller 4 is provided in the inlet pipe 5 and before the pipe 8 to rotate the washing ball 20 so that the washing ball 20 enters the pipe 8 in a scattered form as indicated by the symbol 6. The rotating device ensures that the scouring balls 20 are scattered randomly by the centrifugal force when entering the condenser 7. The second propeller 10 is disposed at the outlet pipe 9 and before the separator 12, it can rotate the fluid and the washing ball 20 so that the washing ball 20 collides with each other at the opening 11 of the separator 12. This can increase the number of collisions between the washing balls 20 to remove the dirt accumulated on the surface of the washing balls 20 after the washing balls 20 pass through the pipeline 8. -12- 200422582 After describing many elements of the erasure system, the operation of the erasure system will be described with reference to FIGS. 1, 2, 3 and 4. We assume an initial position, which is shown in the first figure, whereby the valves VI and V2 are closed, and the washing ball 20 is stacked in the first chamber 19 of the casing 21. There is no fluid flow in the ball transfer tube 24 and the ball return tube 17 because the pressure at the outlet 3 of the ball transfer tube 24 is higher than the pressure at the inlet 13 of the ball return tube 17 and two backstops The function of the valves CV1, CV2. When the condenser 7 is operating, the cooling fluid passes through the inlet pipe 5. According to the principle of fluid mechanics, the static pressure at the inlet 2 of the fluid transfer pipe 23 is higher than the static pressure at the outlet 3 of the ball transfer pipe 24, because the inlet 2 of the fluid transfer pipe 23 is formed to resist the inlet pipe 5. The direction of fluid flow W1. This pressure difference creates a suction force, which can draw fluid from the inlet pipe 5 through the fluid delivery pipe 23 into the housing 21, and draw fluid and wash balls 20 from the housing 21 through the ball delivery pipe 24 to the inlet pipe 5 . In order to allow the rinsing ball 20 to be sucked out of the housing 21 to the inlet pipe 5, the first valve V1 is opened and the second valve V2 is closed, so that the fluid can be sucked into the housing 21 from the inlet pipe 5 and then The washing ball 20 is sucked out of the casing 21 and enters the inlet pipe 5 to circulate to the pipe 8 and the inner wall of the pipe 8 is washed. This is the case shown in Figure 2. The direction in which the fluid flows from the fluid delivery pipe 23 into the casing 21 and the direction in which the washing ball 20 flows from the casing 21 through the check valve CV 1 are shown by the thick arrows in FIG. 2. The device for outputting the rinsing ball 20 and generating the transfer of the rinsing ball 20 is operated by opening the first valve V 1 and keeping the second valve V 2 closed. In this way, the washing ball 20 is sucked from the housing 21 to the upstream of the pipe 8 in accordance with the pressure difference between the inlet 2 of the fluid delivery pipe 23 and the outlet 3-13-22200422 of the ball delivery pipe 24. After all the washing balls 20 are sucked into the inlet pipe 5, the first valve V1 is closed and the second valve V2 remains closed. When the first valve V1 is closed, the feeding of the washing ball 20 is stopped, as shown in FIG. When the first valve V1 is opened, the first propeller 4 is also actuated to force the fluid flow W2 and the washing ball 20 to rotate, so that the washing ball 20 enters the pipeline 8 in a random manner. After the cleaning process, the second propeller 10 rotates the cleaning ball 20 again, causing the cleaning ball 20 to collide with each other, and is removed from the pipeline 8 by the cleaning ball 20 and the dirt currently attached to the cleaning ball 2 0 The particles are erased. Then, the dirt particles are carried by the fluid flow W3 and are discharged through the outlet passage 15. It must be mentioned that the rotation direction of the second propeller 10 and thus the washing ball 20 is preferably opposite to the direction of the inclined long hole 32 of the separator 12. For example, if the length direction of the inclined long hole 32 is counterclockwise, the direction in which the washing ball 20 is rotated by the propeller 10 is preferably clockwise. This can increase the number of collisions of the washing balls 20 with each other. After the rotation, the washing ball 20 accumulates on the opening 11 of the separator 12 as shown in FIG. 3. According to the principle of fluid mechanics, the static pressure at the inlet 13 of the ball return pipe 17 is higher than the static pressure at the outlet 14 of the fluid return pipe 16 because the inlet 1 of the ball return pipe 1 7 3 is formed in a direction that resists the fluid flow W3. Of the outlet pipe 9. This pressure difference forms a suction force, which can suck fluid (and rinse ball 20) from separator 12 via ball return tube 17 and suck into fluid 2 and the fluid (non-wash ball 20 'due to perforation of casing 21) The partition plate 28) is sucked into the outlet channel 15 from the housing 21 via the fluid return pipe 16. -14- 200422582 The device for returning the cleaning ball 20 from the separator 12 to the housing 21 is operated by opening the second valve V 2 and keeping the first valve V1 closed, so the cleaning ball 20 is removed from the separator 1 2 is sucked back into the casing 21, and the fluid (non-washed balls 20, due to the perforated partition 28 of the casing 21) is sucked from the casing 21 to the outlet channel 15. This is the situation shown in Figure 4. The direction in which the fluid and washing ball 20 flows from the ball return tube 17 into the housing 21, and the direction of the fluid from the first chamber 19 into the second chamber 2 7 and then into the fluid return pipe 16 is shown by the thick arrow in. Finally, when all the decontamination balls 20 have returned to the first chamber 19 of the housing 21 and accumulated there, the valves V1 and V2 are closed, as shown in Fig. 1. When the valve V2 is closed, the return operation of the washing ball 20 is stopped. It can be understood that the device for returning the washing ball 20 is operated by opening the second valve V2 and keeping the first valve V1 closed. The device for conveying the scrub ball 20 is operated by opening the first valve V1 and keeping the second valve V2 closed. In both operations, the washing ball 20 is circulated through the recycling device by the operation of the washing ball returning device and the operation of conveying the washing ball device. In both operations, the two valves V1 and V2 are opened and closed, or closed and opened, between the inlet 13 of the ball return pipe 17 and the outlet 14 of the fluid return pipe 16, and between the fluid A pressure difference is caused between the inlet 2 of the transfer pipe 23 and the outlet 3 of the ball transfer pipe 24. Therefore, the operation of the entire depletion system can be easily controlled via two manually or mechanically operated valves V1 and V2. When demand arises, when the 淸 wash ball 20 must be replaced, the manual valves ΗV 1, HV2 are closed, and the cover 18 is opened, so that the 淸 wash ball 20 can be replaced. Although the present invention has been described herein with reference to preferred embodiments, it must be understood that those skilled in the art can make many changes and applications or modifications without departing from the scope defined by the scope of the patent application accompanying the present invention. -15- 200422582 The advantageous effects of the present invention can be seen from the above embodiments. The operation of the entire depletion system can be easily controlled through two valves VI and V2. Operate automatically. Also, the entire depletion system has limited moving parts, making it more reliable and requiring less maintenance. In addition to this, the purging system does not waste cooling fluid, which can be recirculated along with the purging balls 20. V. Simple illustration
