在進行污水處理或者淨水處理所產生的沉澱物一般被稱為污泥，此時的污泥的含水率占整體重量的百分之七十至百分之八十(含水率70%~80%)，通常須將汙泥的含水率乾燥至20%~30%，才有利於回收再利用，例如：作為堆肥材料。
近年來發展出一種直接供應水氣含量低之熱空氣或冷空氣至儲存汙泥之器具中以減少汙泥中的水氣之汙泥處理方法，並且，發展出一種汙泥乾燥設備，透過高溫熱能使得該汙泥乾燥設備中的汙泥處於一高溫狀態，以使汙泥中之水氣被蒸發，以減少汙泥的重量與體積，便能減少汙泥中的水氣含量。
上述的汙泥乾燥設備是經由一加熱乾燥法(例如：經由旋轉爐或旋轉盤加熱)，也就是利用攝氏800度或溫度更高之熱空氣與汙泥的接觸來乾燥汙泥。然而，由於汙泥的外部已先吸收了所有熱能以蒸發水氣，熱能的傳導便被阻擋在汙泥的外部範圍，所以該熱能無法傳導至汙泥的內部區域，導致處理汙泥的效果不佳。此外，汙泥的黏性導致汙泥自身容易形成團粒結構(結球)，該團粒結構也會降低烘乾汙泥的功效。
因此，如何能夠提升污泥的處理效果，降低汙泥的含水率，是值得本領域具有通常知識者去衡量地。
The sediment produced during sewage treatment or water purification treatment is generally called sludge. At this time, the moisture content of the sludge accounts for 70% to 80% of the overall weight (moisture content 70% to 80%). %), usually the moisture content of the sludge must be dried to 20%~30% before it can be recycled and reused, for example: as compost material.
In recent years, a sludge treatment method has been developed that directly supplies hot air or cold air with low water vapor content into equipment storing sludge to reduce the water vapor in the sludge. Moreover, a sludge drying equipment has been developed that uses high-temperature sludge drying equipment. Warm heat can cause the sludge in the sludge drying equipment to be in a high temperature state, so that the water vapor in the sludge can be evaporated to reduce the weight and volume of the sludge, thus reducing the water vapor content in the sludge.
The above-mentioned sludge drying equipment uses a heating drying method (for example, heating via a rotary furnace or rotating disk), that is, the contact between hot air at 800 degrees Celsius or higher and the sludge is used to dry the sludge. However, since the outside of the sludge has first absorbed all the heat energy to evaporate water vapor, the conduction of heat energy is blocked in the outer range of the sludge, so the heat energy cannot be conducted to the inner area of the sludge, resulting in ineffective sludge treatment. good. In addition, the viscosity of the sludge causes the sludge itself to easily form an aggregate structure (balling), which will also reduce the efficiency of drying the sludge.
Therefore, how to improve the treatment effect of sludge and reduce the moisture content of sludge is worthy of consideration by those with general knowledge in this field.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings.
請參閱圖1A及圖1B，圖1A所繪示為汙泥烘乾系統10的示意圖，圖1B所繪示為汙泥烘乾系統10移除頂蓋15的示意圖。本發明之汙泥烘乾系統10包括一主殼體11、一第一螺旋桿組件12、一第二螺旋桿組件13、一驅動馬達14、一頂蓋15及多個紅外線加熱裝置16。其中，驅動馬達14是位於主殼體11的外部，而頂蓋15是設置於主殼體11的正上方。
上述中，主殼體11的一端設有一汙泥置入口11A，主殼體11的另一端設有一汙泥出口11B，汙泥置入口11A位於第一螺旋桿組件12及第二螺旋桿組件13的上方，汙泥出口11B是位於第一螺旋桿組件12及第二螺旋桿組件13的下方。此外，含水率70%~80%的污泥是從汙泥置入口11A投入，而處理後的汙泥(含水率20%~30%的汙泥)則是經由汙泥出口11B送出。
請參閱圖2A、圖2B及圖2C，圖2A及圖2B所繪示為第一螺旋桿組件12及第二螺旋桿組件13及驅動馬達14的示意圖，圖2C所繪示為驅動馬達14經由鏈條141連結第一齒輪121的示意圖。第一螺旋桿組件12是包括一第一齒輪121、一第一圓桿122、一第一螺旋片123及多個第一延伸柱124，而第二螺旋桿組件13是包括一第二齒輪131、一第二圓桿132、一第二螺旋片133及多個第二延伸柱134。其中，第一齒輪121是設置在主殼體11的外部，第一圓桿122、第一螺旋片123及第一延伸柱124皆是設置在主殼體11內，第一圓桿122是平行於第二圓桿132。另外，兩相鄰的第一延伸柱124是具有一適當間距，且第一螺旋片132及第二螺旋片133是相互交錯。
此外，第一圓桿122的一端是連結第一齒輪121，而第一螺旋片123是環繞第一圓桿122。並且，這些第一延伸柱124是連結在第一圓桿122及第一螺旋片123之間，每一個第一延伸柱124是設有一第一撥片124P。在本實施例中，第一螺旋往上片123是用以攪拌汙泥及推送汙泥往汙泥出口11B的方向移動，而第一撥片124P是用以將汙泥往上撥動，有助於打碎汙泥的團粒結構(結球)，增加汙泥與空氣的接觸面積。
另外，第二齒輪131是齧合於第一齒輪121，第二圓桿132的一端是連結第二齒輪131，且第二螺旋片133是環繞於第二圓桿132。在本實施例中，第二螺旋片133環繞於第二圓桿132的方向是不同第一螺旋片123環繞於第一圓桿122的方向；更詳細的說，第二螺旋片133環繞於第二圓桿132的方向是相反於第一螺旋片123環繞於第一圓桿122的方向。此外，第一螺旋桿組件12及第二螺旋桿組件13是屬於相同的結構，只是兩造的組裝方向不同，導致第一螺旋片123與第二螺旋片133具有相反的環繞方向。
並且，第二圓桿132、第二螺旋片133及第二延伸柱134皆是設置在主殼體11內，這些第二延伸柱134是連結在第二圓桿132及第二螺旋片133之間。此外，兩相鄰的第二延伸柱134是具有一適當間距，且每一個第二延伸柱134是設有一第二撥片134P。在本實施例中，第二螺旋片133是用以攪拌汙泥及推送汙泥往汙泥出口11B的方向移動，而第二撥片134P是用以將汙泥往上撥動，同樣有助於打碎汙泥的團粒結構(結球)，並增加汙泥與空氣的接觸面積。
請再次參閱圖2C，驅動馬達14是經由一鏈條141連結第一齒輪121，以使驅動馬達14驅動第一齒輪121進行轉動。並且，轉動的第一齒輪121也會同時帶動第二齒輪131進行不同方向的轉動。詳細來說，第一齒輪121是逆時針轉動，而造成第二齒輪131便會進行順時針轉動。因此，第一螺旋桿組件12本身的轉動方向是不同於第二螺旋桿組件13的轉動方向。如此一來，汙泥會分別在主殼體11的兩側邊被第一撥片124P及第二撥片134P往上撥動，有助於打碎汙泥的團粒結構(結球)，還能使汙泥內的水氣向外部散發。
上述中，由於第二螺旋片133環繞於第二圓桿132的方向是不同第一螺旋片123環繞於第一圓桿122的方向，且第一螺旋桿組件12本身的轉動方向是不同於第二螺旋桿組件13的轉動方向，所以被第一螺旋片123與第二螺旋片133攪拌的汙泥便朝同一方向前進，也就是朝著汙泥出口11B的方向移動(請參閱圖1A)。
請再次參閱圖1A，所有的紅外線加熱裝置16是位於主殼體11的正下方，這些紅外線加熱裝置16是用以加熱所需處理的汙泥(含水率70%~80%的污泥)，以降低汙泥的含水量。
在上述的實施例中，主要是揭露汙泥烘乾系統10的架構為主，下列將配合圖3中的汙泥的處理方法來說明汙泥烘乾系統10如何處理含水率70%~80%的汙泥。
首先，請參閱步驟S1，提供一汙泥，該汙泥的含水率約為70%~80% 。之後，請參閱步驟S2，將多個奈米矽片及一適量的酵素加入該汙泥內，以形成一待處理汙泥。詳細來說，多個奈米矽片與酵素尚未均勻的混入該汙泥內的狀態被定義為該待處理汙泥。然後，請參閱步驟S3，該待處理汙泥經由汙泥置入口11A投入於主殼體11內，以使該待處理汙泥接觸到第一螺旋片123、第一撥片124P、第二螺旋片133及第二撥片134P。上述中，所使用到的奈米矽片為維騰環保科技有限公司所生產的「ecoSi 艾克思」奈米矽片，每個奈米矽片的體積為 100×100×1nm
3片狀物，且每片「ecoSi 艾克思」奈米矽片是帶有 20,000個負電荷，所以對於細菌具有極佳的物理捕捉性。
接著，請參閱步驟S4，經由第一螺旋桿組件12及第二螺旋桿組件13攪拌且撥動該待處理汙泥。詳細來說，第一螺旋片123與第二螺旋片133是用以攪拌該待處理汙泥及推送該待處理汙泥往汙泥出口11B的方向移動。並且，第一撥片124P及第二撥片134P是用以將汙泥往上撥動，增加該待處理汙泥與空氣的接觸面積，更有助於熱能傳導至汙泥的內部區域。此外，透過第一螺旋片123與第二螺旋片133攪拌該待處理汙泥，此時的奈米矽片與酵素便能均勻的混入於該待處理汙泥內。
再來，請參閱步驟S5，經由所述的紅外線加熱裝置16加熱該待處理汙泥，以形成一乾燥汙泥。具體來說，紅外線加熱裝置16經由紅外線加熱被攪拌及撥動中的汙泥，以將汙泥的水氣引導到上方的空氣中，便能將汙泥的含水率乾燥至20%~30%的範圍(該乾燥汙泥)。
之後，請參閱步驟S6，經由汙泥出口11B送出該乾燥汙泥。其中，含水率20 %左右的汙泥便適合作為堆肥材料。並且。該乾燥汙泥內的奈米矽片能利用物理電荷吸附作用來捕捉細菌，發揮滅菌的功效，以清除該乾燥汙泥內的細菌，並去除或螯合有毒重金屬。如此一來，富含天然奈米矽片的乾燥汙泥便能替代化學農藥被土壤吸收，對於農作物的收成能增加20%左右的產量。此外，適量的酵素有助於減少土壤中養分被固定與沉澱，使得營養要素能夠充分為植物吸收利用。
請參閱圖4，圖4所繪示為堆疊四台汙泥烘乾系統10的示意圖。在上述的實施例中是一台汙泥烘乾系統10對汙泥進行處理。然而，在其他的實施例中也能使用多台汙泥烘乾系統10由上而下進行堆疊，例如圖4所顯示的推疊四台汙泥烘乾系統10。其中，上方的汙泥烘乾系統10的汙泥出口11B皆是對應於下方另一台汙泥烘乾系統10的一汙泥置入口11A。因此，該待處理汙泥便能同時透過四台汙泥烘乾系統10以一條龍的方式進行乾燥處理。這樣一來，更能確保提升污泥的處理效果，降低汙泥的含水率。
雖然本發明已以較佳實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。

The sludge inlet 11A is located in the first screw assembly 12 and the second screw assembly 13 above, the sludge outlet 11B is located below the first screw assembly 12 and the second screw assembly 13 . In addition, sludge with a moisture content of 70% to 80% is input from the sludge inlet 11A, and the treated sludge (sludge with a moisture content of 20% to 30%) is sent out through the sludge outlet 11B. Please refer to Figures 2A, 2B and 2C. Figures 2A and 2B show schematic diagrams of the first screw assembly 12, the second screw assembly 13 and the drive motor 14. Figure 2C shows the drive motor 14 via Schematic diagram of the chain 141 connecting the first gear 121 . The first screw assembly 12 includes a first gear 121, a first round rod 122, a first spiral blade 123 and a plurality of first extension columns 124, and the second screw assembly 13 includes a second gear 131 , a second round rod 132 , a second spiral piece 133 and a plurality of second extension columns 134 . Among them, the first gear 121 is arranged outside the main housing 11, the first round rod 122, the first spiral piece 123 and the first extension column 124 are all arranged inside the main housing 11, and the first round rod 122 is parallel on the second round rod 132. In addition, two adjacent first extending columns 124 have an appropriate spacing, and the first helical pieces 132 and the second helical pieces 133 are staggered with each other. In addition, one end of the first round rod 122 is connected to the first gear 121 , and the first spiral piece 123 surrounds the first round rod 122 . Moreover, these first extension columns 124 are connected between the first round rod 122 and the first spiral piece 123, and each first extension column 124 is provided with a first paddle 124P. In this embodiment, the first spiral upward piece 123 is used to stir the sludge and push the sludge toward the direction of the sludge outlet 11B, and the first paddle 124P is used to stir the sludge upward. Helps break up the sludge's granular structure (balling) and increases the contact area between sludge and air. In addition, the second gear 131 is meshed with the first gear 121 , one end of the second round rod 132 is connected to the second gear 131 , and the second spiral piece 133 surrounds the second round rod 132 . In this embodiment, the direction in which the second spiral piece 133 surrounds the second round rod 132 is different from the direction in which the first spiral piece 123 surrounds the first round rod 122; more specifically, the direction in which the second spiral piece 133 surrounds the first round rod 122 is different. The direction of the two round rods 132 is opposite to the direction in which the first spiral piece 123 surrounds the first round rod 122 . In addition, the first screw assembly 12 and the second screw assembly 13 have the same structure, but their assembly directions are different, resulting in the first spiral piece 123 and the second spiral piece 133 having opposite circumferential directions. Moreover, the second round rod 132, the second spiral piece 133 and the second extension column 134 are all arranged in the main housing 11, and these second extension columns 134 are connected between the second round rod 132 and the second spiral piece 133. between.

It is used to break up the aggregate structure (balling) of sludge and increase the contact area between sludge and air. Please refer to FIG. 2C again. The driving motor 14 is connected to the first gear 121 through a chain 141 so that the driving motor 14 drives the first gear 121 to rotate. Moreover, the rotating first gear 121 will also drive the second gear 131 to rotate in different directions. Specifically, the first gear 121 rotates counterclockwise, causing the second gear 131 to rotate clockwise. Therefore, the rotation direction of the first screw rod assembly 12 itself is different from the rotation direction of the second screw rod assembly 13 . In this way, the sludge will be moved upward by the first paddle 124P and the second paddle 134P on both sides of the main housing 11, which helps to break up the sludge's granular structure (balling), and can also Let the water vapor in the sludge escape to the outside. In the above, since the direction in which the second spiral piece 133 surrounds the second round rod 132 is different from the direction in which the first spiral piece 123 surrounds the first round rod 122, and the rotation direction of the first spiral rod assembly 12 itself is different from the direction in which the first spiral piece 123 surrounds the first round rod 122, The rotation direction of the two screw rod assembly 13 is so that the sludge stirred by the first screw blade 123 and the second screw blade 133 moves in the same direction, that is, toward the sludge outlet 11B (see Figure 1A). Please refer to Figure 1A again. All infrared heating devices 16 are located directly below the main housing 11. These infrared heating devices 16 are used to heat the sludge to be treated (sludge with a moisture content of 70% to 80%). to reduce the moisture content of sludge. In the above embodiment, the structure of the sludge drying system 10 is mainly disclosed. The following will illustrate how the sludge drying system 10 processes the moisture content of 70% to 80% in conjunction with the sludge treatment method in Figure 3. of sludge. First, please refer to step S1 to provide a sludge with a moisture content of approximately 70% to 80%. Afterwards, please refer to step S2 to add a plurality of silicon nanosheets and an appropriate amount of enzyme into the sludge to form a sludge to be treated. Specifically, the state in which multiple silicon nanochips and enzymes are not evenly mixed into the sludge is defined as the sludge to be treated. Then, please refer to step S3. The sludge to be treated is put into the main housing 11 through the sludge insertion port 11A, so that the sludge to be treated contacts the first spiral piece 123, the first paddle 124P, and the second spiral piece. piece 133 and the second pick 134P. In the above, the silicon nanosheets used are "ecoSi" silicon nanosheets produced by Witten Environmental Protection Technology Co., Ltd., and the volume of each silicon nanosheet is 100×100×1nm 3 sheets. , and each "ecoSi" nano silicon chip has 20,000 negative charges, so it has excellent physical capture properties for bacteria. Next, please refer to step S4 to stir and stir the sludge to be treated through the first screw assembly 12 and the second screw assembly 13 . Specifically, the first spiral blade 123 and the second spiral blade 133 are used to stir the sludge to be treated and push the sludge to be treated toward the direction of the sludge outlet 11B. In addition, the first paddle 124P and the second paddle 134P are used to push the sludge upward to increase the contact area between the sludge to be treated and the air, and further facilitate the conduction of heat energy to the internal area of the sludge. In addition, by stirring the sludge to be treated through the first spiral blade 123 and the second spiral blade 133, the silicon nanosheets and enzymes can be evenly mixed into the sludge to be treated. Next, please refer to step S5 to heat the sludge to be treated through the infrared heating device 16 to form dry sludge. Specifically, the infrared heating device 16 heats the stirred and stirred sludge through infrared rays to guide the moisture of the sludge into the air above, thereby drying the moisture content of the sludge to 20%~30%. range (the dry sludge). Afterwards, please refer to step S6 to send the dried sludge through the sludge outlet 11B. Among them, sludge with a moisture content of about 20% is suitable as compost material. And. The nano-silica chips in the dry sludge can use physical charge adsorption to capture bacteria and exert a sterilization effect to remove bacteria in the dry sludge and remove or chelate toxic heavy metals. In this way, dry sludge rich in natural silicon nanoflakes can be absorbed into the soil instead of chemical pesticides, which can increase crop yields by about 20%. In addition, an appropriate amount of enzymes can help reduce the fixation and precipitation of nutrients in the soil, so that nutrients can be fully absorbed and utilized by plants. Please refer to FIG. 4 , which is a schematic diagram of stacking four sludge drying systems 10 . In the above embodiment, a sludge drying system 10 processes the sludge. However, in other embodiments, multiple sludge drying systems 10 can also be stacked from top to bottom, for example, four sludge drying systems 10 are stacked as shown in FIG. 4 . Among them, the sludge outlet 11B of the sludge drying system 10 above corresponds to a sludge inlet 11A of the other sludge drying system 10 below. Therefore, the sludge to be treated can be dried simultaneously through four sludge drying systems 10 in a one-stop manner. In this way, it is better to ensure that the sludge treatment effect is improved and the moisture content of the sludge is reduced. Although the present invention has been disclosed above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone with ordinary skill in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. , therefore, the protection scope of the present invention shall be determined by the appended patent application scope.
