Description
一種汚泥衍生燃料，尤指利用有機汚泥混合咖啡渣所形成之燃料。 A sludge-derived fuel, especially a fuel formed by mixing organic coffee sludge with coffee grounds.
按，下水道汚水處裡後會產生大量的汚泥，一般的處理方法是將其汚泥經脫水或乾燥後，形成含水量低於百分之七十以下之汚泥餅，再以掩埋方式棄置，此種方式未來會造成嚴重的環境負荷，因此，世界各國都致力發展下水道汚泥的再生利用方法，降低下水道汚泥對環境的影響，目前對於下水道汚泥之再生利用大致上有熱能回收、再生利用、焚化灰渣材料以及農業土地利用。 According to the sewerage, there will be a large amount of sludge in the sewerage. The general treatment method is to dewater or dry the sludge to form a sludge cake with a water content of less than 70%, and then dispose of it in a buried manner. The future will cause severe environmental load. Therefore, all countries in the world are committed to developing the recycling method of sewage sludge and reducing the impact of sewage sludge on the environment. At present, there are roughly heat recovery, recycling and incineration ash for the recycling of sewage sludge. Materials and agricultural land use.
由於下水道汚泥為含有高量熱值之有機物質，並具有低灰分之特性，以國內下水道汚泥為例其發熱量約為13100KJ/KG至18700KJ/KG，若直接將下水道汚泥脫水乾燥製成汚泥衍生燃料(sludge-derived fuel)，不論是存放或是使用，皆會產生惡臭造成環境汚染及公害，因此，即有相關業者將脫水乾燥後的汚泥，以加熱乾燥製成焦炭，或是經熱解後產生燃氣與燃油，此種方式之處理成本相當的高，且為利用大量的資源讓汚泥可生成衍生燃料使用，相對之下，所獲得的效益就相當的低。 Since the sewage sludge is an organic substance containing a high amount of calorific value and has a low ash characteristic, the domestic sewage sludge is taken as an example, and its calorific value is about 13100 KJ/KG to 18700 KJ/KG. If the sewage sludge is directly dehydrated and dried to form sludge derivatization. Sludge-derived fuel, whether stored or used, will cause environmental pollution and pollution caused by foul odor. Therefore, the relevant producers will dehydrate the dried sludge to produce coke by heat drying or pyrolysis. After the generation of gas and fuel, the treatment cost of this method is quite high, and the use of a large amount of resources allows the sludge to be used to generate derivative fuels, and the benefits obtained are relatively low.
是以，要如何有效的將下水道汚泥製成汚泥衍生燃料，並可降低汚泥衍生燃料對環境之汙染與其所造成之公害，即為相關業 者所亟欲研發之課題。 Therefore, how to effectively make sewage sludge into sludge-derived fuel, and reduce the environmental pollution caused by sludge-derived fuel and the pollution caused by it, The subject of research and development.
本發明之主要目的在於，利用有機汚泥形成汚泥衍生燃料，使燃料於存放或經燃燒反應釋放能量時，降低對空氣之汚染，並提升汚泥衍生燃料之使用價值。 The main object of the present invention is to form sludge-derived fuel by using organic sludge to reduce the pollution of air when the fuel is stored or released by the combustion reaction, and to enhance the use value of the sludge-derived fuel.
為達上述目的，本發明之汚泥衍生燃料，係以有機汚泥經乾燥與粉碎並混合咖啡渣所形成，利用咖啡渣減少有機汚泥於存放或是經燃燒反應釋放能量時所產生之臭味，降低對空氣之汚染，且製作過程簡單，提升汚泥衍生燃料之使用價值。 In order to achieve the above object, the sludge-derived fuel of the present invention is formed by drying and pulverizing and mixing coffee grounds with organic sludge, and using coffee grounds to reduce the odor generated by the organic sludge when stored or released by the combustion reaction, and is reduced. The pollution of the air, and the production process is simple, and the use value of the sludge-derived fuel is improved.
前述之汚泥衍生燃料，其中該有機汚泥係為處理下水道廢水時所產生。 The aforementioned sludge-derived fuel, wherein the organic sludge is produced when treating sewage water.
前述之汚泥衍生燃料，其中該有機汚泥混合咖啡渣後，係以擠壓成型方式製成棒狀或粒狀。 The sludge-derived fuel described above, wherein the organic sludge is mixed with coffee grounds, and is formed into a rod shape or a granular shape by extrusion molding.
第一圖 係為本發明之流程圖。 The first figure is a flow chart of the present invention.
請參閱第一圖所示，本發明於製造汚泥衍生燃料時，係依照下列步驟進行： Referring to the first figure, the present invention is carried out in the following steps in the manufacture of sludge-derived fuel:
(A)脫水：將廢水處理廠於處理下水道廢水時所產生之有機汚泥，利用脫水方式將其乾燥，降低有機汚泥的含水量，使有機汚泥形成固態。 (A) Dehydration: The organic sludge produced by the wastewater treatment plant in the treatment of sewage water is dried by dehydration, and the water content of the organic sludge is reduced to form a solid state of the organic sludge.
(B)粉碎混合：將固態之有機汚泥粉碎，並添加咖啡渣混合。 (B) Crushing and mixing: The solid organic sludge is pulverized, and coffee grounds are added and mixed.
(C)擠壓成型：將粉碎後混合有咖啡渣之汚泥，以擠壓方式壓縮成 密度較大的粒狀、棒狀、塊狀等各種形狀之衍生燃料，以方便燃燒使用。 (C) Extrusion: the sludge mixed with coffee ground after crushing is compressed into a squeezed manner Derivative fuels of various shapes such as granular, rod-shaped, and blocky materials with high density for convenient combustion.
再者，本發明之衍生燃料特別選用咖啡渣混合有機汚泥，其 重點如下： Furthermore, the derivative fuel of the present invention particularly uses coffee grounds mixed organic sludge, Highlights are as follows:
1、咖啡渣屬於多孔性結構之有機物質，其含碳量高達50%以上，可有效地去吸附有機汚泥所產生的臭味，大幅降低衍生燃料存放或是經燃燒反應釋放能量時所產生之臭味，且咖啡渣燃燒時亦會釋放出大量熱能，提高燃燒效能。 1. Coffee slag is an organic substance with a porous structure. Its carbon content is as high as 50% or more, which can effectively absorb the odor generated by organic sludge, and greatly reduce the storage of derivative fuel or the release of energy through combustion reaction. Odor, and coffee slag will also release a lot of heat when burning, improving combustion efficiency.
2、咖啡豆經烘焙、研磨形成咖啡粉，而沖泡咖啡後所殘留之咖啡渣亦成粉狀，故只需將咖啡渣乾燥後即可使用，完全不需再製加工，且咖啡渣亦屬廢棄物，因此，本發明之衍生燃料除了可有效利用下水道汚泥外，亦同時解決了咖啡渣廢棄物之問題。 2. The coffee beans are roasted and ground to form coffee powder, and the coffee ground residue remaining after brewing the coffee is also powdered. Therefore, the coffee grounds can be used only after drying, and no need to be processed any more, and the coffee grounds are also Waste, therefore, the derivative fuel of the present invention not only effectively utilizes sewage sludge, but also solves the problem of coffee ground waste.
另，在製造汚泥衍生燃料時，係可於粉粹混合的過程中添加纖維質污泥，例如：於處理造紙廢水時所產生之紙漿污泥，此種纖維質污泥亦為有機成分，利用纖維質污泥中的纖維，可讓衍生燃料於擠壓成型的過程更加容易，即纖維質污泥作為衍生燃料中的結合劑使用。 In addition, in the production of sludge-derived fuel, fibrous sludge can be added during the mixing process, for example, pulp sludge generated in the treatment of papermaking wastewater, which is also an organic component. The fibers in the fibrous sludge make the process of extrusion of the derivative fuel easier, that is, the fibrous sludge is used as a binder in the derivative fuel.
