隨著科技的進步,能源的需求與消耗日益提高,然而石化燃料的蘊藏有限且其成本逐年增加,因此再生能源的開發與利用便成為現今各國爭相研發之課題。 With the advancement of technology, the demand and consumption of energy is increasing. However, the accumulation of fossil fuels is limited and its cost is increasing year by year. Therefore, the development and utilization of renewable energy has become the subject of research and development in various countries.
顆粒燃料係為一種新類型的燃料,屬再生能源生質能之固態燃料。一般而言,顆粒燃料之主要原料為生質物(例如植物或其廢棄物),經過破碎、乾燥與造粒等步驟使蓬鬆的原料成為密實的粒狀,大幅減少原料的體積,在相同容積下能儲存較多的熱能,可提高原料的燃燒效率,便於運送及儲藏,並具有低污染的優點。目前,顆粒燃料已廣泛應用於各種工業設備或公共設施之加熱系統,例如鍋爐,以作為替代燃料使用。由於燃料顆粒之能源投資報酬率較高,可預期地顆粒燃料之未來市場需求將會大幅增加。 The particulate fuel is a new type of fuel that is a solid fuel for renewable energy. In general, the main raw material of the particulate fuel is a raw material (such as a plant or its waste). After the steps of crushing, drying and granulating, the fluffy raw material is made into a dense granular shape, and the volume of the raw material is greatly reduced, under the same volume. It can store more heat energy, improve the combustion efficiency of raw materials, facilitate transportation and storage, and has the advantage of low pollution. At present, particulate fuel has been widely used in heating systems of various industrial equipment or public facilities, such as boilers, as an alternative fuel. Due to the high energy return on fuel pellets, it is expected that the future market demand for pellet fuel will increase significantly.
環保科技亦為現今各國著重發展的領域之一。廢棄物衍生燃料(Refuse Derived Fuel,RDF)為將廢棄物經不同處理程序製成燃料之技術,其不只可以將廢棄物減量,且可作為替代燃料使用, 達到節能減碳之目的。 Environmental technology is also one of the areas where countries are now focusing on development.

The biological sludge is the main waste of the sewage treatment plant. It is the waste generated by the various waste water in the sewage sewer that is deposited on the bottom and processed after the artificial purification of water. However, as production has increased year by year, the subsequent treatment of biological sludge has become an increasingly important issue. At present, the treatment methods of biological sludge are mainly landfill method and composting method. Among them, the buried method requires the problem of landfill site and subsequent site utilization. The composting law is less decontamination. As for other advanced methods, it is too expensive to process. practical.

In the present embodiment, the particle size of the derivatized particulate fuel is preferably from 6 mm to 8 mm, but not limited thereto.
請參閱第二圖,其係為本案另一較佳實施例之生質物混合生物污泥之衍生顆粒燃料之製法流程圖。於本實施例中,製造生質物混 合生物污泥之衍生顆粒燃料之主要步驟與第一圖所示實施例相似,於此不再贅述,惟於步驟S11及步驟S12中,更可包括檢測生物污泥及生質物之熱值之步驟。於另一實施例中,於步驟S11及步驟S12中更可包括檢測生物污泥及生質物之灰分及含水率之步驟。於本實施例中,於步驟S11及步驟S12之後,更可包括由檢測而得的生物污泥與生質物的熱值,配比出具所需目標熱值之衍生顆粒燃料的步驟S125。舉例而言,如適合一工業鍋爐需求的衍生顆粒燃料之目標熱值設定為約3800卡/克,且檢測得知原料生物污泥的熱值為3230卡/克,原料生質物的熱值為4350卡/克時,可估算得生物污泥對生質物的重量百分比需約為:50:50,因此便可利用估算取得的生物污泥對生質物的特定重量百分比進行後續混合物料及壓製成衍生顆粒燃料之步驟。於一些實施例中,於步驟S125中,更可包括由檢測而得的生物污泥與生質物的熱值、灰分及含水率,配比出具所需目標熱值及灰分之衍生顆粒燃料或具所需特性之衍生顆粒燃料的步驟。 Please refer to the second figure, which is a flow chart of a method for preparing a derivative particulate fuel of bio-mixed biological sludge according to another preferred embodiment of the present invention. In this embodiment, the raw material mixture is manufactured. The main steps of the bio-sludge-derived granule fuel are similar to the embodiment shown in the first figure, and will not be further described herein. However, in step S11 and step S12, the calorific value of the biological sludge and the biomass can be detected. step. In another embodiment, the step of detecting the ash and moisture content of the biological sludge and the biomass is further included in steps S11 and S12. In this embodiment, after step S11 and step S12, step S125 of extracting the derived particulate fuel having the desired target heating value may be further included by detecting the calorific value of the biological sludge and the biomass. For example, if the target calorific value of the derivative pellet fuel suitable for an industrial boiler demand is set to about 3800 cal/g, and the calorific value of the raw material biological sludge is found to be 3230 cal/g, the calorific value of the raw biomass is At 4,350 calories per gram, it can be estimated that the weight percentage of biological sludge to raw material needs to be about 50:50, so that the estimated weight percentage of the biological sludge can be used to carry out the subsequent mixture and the derivative into a derivative. The step of pellet fuel. In some embodiments, in step S125, the calorific value, the ash content, and the moisture content of the biological sludge and the biomass obtained by the detection may be further included, and the derivative particulate fuel or the ash having the desired target calorific value and ash is produced. The step of deriving the particulate fuel of the desired characteristics.
於本實施例中,熱值係採用NIEA R 214.01C方法以燃燒彈熱卡計檢測而得。灰分則以NIEA R205.01C方法檢測而得,其中灰分表示待測物於高溫爐中加熱灰化後的殘留物佔原重量的比例。含水率可採CNS452木材含水率試驗法操作之,其係將試體乾燥至恆量,並計算乾燥後試體質量損失之百分比。由於該些性質及其檢測方法係為本領域技術人員所熟習者,於此不再贅述。 In the present embodiment, the calorific value is obtained by the NIEA R 214.01C method using a thermal bomb calorimeter. The ash is obtained by the method of NIEA R205.01C, wherein the ash represents the ratio of the residue of the test object to the original weight after heating and ashing in the high temperature furnace. The water content can be operated by the CNS452 wood moisture test method, which is to dry the test piece to a constant amount and calculate the percentage loss of the sample after drying. Since these properties and their detection methods are familiar to those skilled in the art, they will not be described again.
於一實施例中,生質物為柳杉,其係為木本植物,且生物污泥係取自於污水處理廠,藉以製造本案之生質物混合生物污泥之衍生顆粒燃料。請參閱表一,其係為以生質物與生物污泥之各種不同 配比製成之衍生顆粒燃料之特性表,其中S3W7表示生物污泥佔總重量的30%,柳杉佔70%;S5W5表示生物污泥佔總重量的50%,柳杉佔50%;S7W3表示生物污泥佔總重量的70%,柳杉佔30%。由表一可知,依據本案製法所產出的衍生顆粒燃料皆具有較佳的整體密度,因此可降低儲存及運送的成本。此外,增加生物污泥的重量比例會降低熱值、提高灰分,增加柳杉的重量比例則會提高熱值、降低灰分,換言之,生物污泥的特性為低熱值高灰分,柳杉則為高熱值低灰分,且生物污泥與柳杉的熱值及灰分大致成線性關係,可依混合的比例推得其混合後的熱值及灰分。因此,藉由本案之製法可產製出具所需熱值及灰份等特性之衍生顆粒燃料,以適用於所需的加熱系統,例如工業鍋爐。舉例而言,如顆粒燃料之灰分過高,將使加熱系統的燃燒效率降低,並衍生後續粉塵排放的處理問題,因以藉由本案之製法可產製出具所需熱值及灰份等特性之衍生顆粒燃料,以適用於所需的加熱系統。 In one embodiment, the biomass is cedar, which is a woody plant, and the biological sludge is taken from a sewage treatment plant to produce a derivative particulate fuel of the biological biomass mixed biological sludge of the present invention. Please refer to Table 1, which is based on the difference between biomass and biological sludge. The characteristic table of the derivative granular fuel produced by the ratio, wherein S3W7 represents that the biological sludge accounts for 30% of the total weight, the cedar accounts for 70%; the S5W5 represents that the biological sludge accounts for 50% of the total weight, and the cedar accounts for 50%; S7W3 It means that the biological sludge accounts for 70% of the total weight, and the cedar accounts for 30%. It can be seen from Table 1 that the derivative particulate fuel produced according to the method of the present invention has a better overall density, thereby reducing the cost of storage and transportation. In addition, increasing the weight ratio of biological sludge will reduce the calorific value and increase the ash content. Increasing the weight ratio of cedar will increase the calorific value and reduce the ash. In other words, the characteristics of the biological sludge are low calorific value and high ash, and the cedar is high fever. The value is low ash, and the calorific value and ash content of the biological sludge and the cedar are approximately linear, and the calorific value and ash of the mixture can be derived according to the mixing ratio. Therefore, by the method of the present invention, a derivative particulate fuel having the desired calorific value and ash content can be produced to be applied to a desired heating system such as an industrial boiler. For example, if the ash content of the particulate fuel is too high, the combustion efficiency of the heating system will be lowered, and the subsequent dust discharge treatment problem will be derived, because the desired heating value and ash content can be produced by the method of the present invention. Derivatized particulate fuel to suit the heating system required.
於本實施例中,本案之生質物混合生物污泥之衍生顆粒燃料具有 較佳之顆粒堅牢度(Pellet Durability Index,PDI),其中顆粒堅牢度係以ASAE S269.5的方法測試,其表示造粒而得的顆粒在遭受外力而擠壓或翻滾時保持顆粒的完整程度。含水率為影響顆粒堅牢度的因素之一,原生生物污泥的含水率較高,為使衍生顆粒燃料具有較佳之顆粒堅牢度,可將原生生物污泥先初步脫水,使混合物料含水率介於10%至25%之間,則將使造粒而得的衍生顆粒燃料具有較佳的顆粒堅牢度。 In this embodiment, the biomass-derived biological sludge-derived particulate fuel of the present invention has Preferred Pellet Durability Index (PDI), wherein the particle fastness is tested by the method of ASAE S269.5, which means that the granulated particles retain the integrity of the granules when subjected to external forces to squeeze or tumble. The water content is one of the factors affecting the fastness of the particles. The moisture content of the raw biological sludge is relatively high. In order to make the derived granular fuel have better particle fastness, the primary biological sludge can be preliminarily dehydrated to make the moisture content of the mixture. Between 10% and 25%, the granulated derived particulate fuel will have better particle fastness.
於一些實施例中,提高混合物料之造粒環境的溫度有助於提昇衍生顆粒燃料之堅牢度。於本實施例中,混合物料壓製成衍生顆粒燃料之較佳環境溫度為攝氏80度以上,並以連續壓製之方式製成複數個衍生顆粒燃料。於本實施例中,造粒過程中環境溫度的提高,使生物污泥中所包含的蛋白質以及生質物中所包含的木質素熔融,並於冷卻後凝固,形成膠合狀態,具有黏著劑的效果,使衍生顆粒燃料較密實,有較佳的顆粒堅牢度,因此混合物料無需另行添加黏著劑即可造粒成型。當然,於另一些實施例中,於造粒過程中亦可選擇添加一些黏著劑,以助於顆粒的成形及愈加提高其顆粒堅牢度。 In some embodiments, increasing the temperature of the granulation environment of the blend material helps to increase the fastness of the derivatized particulate fuel. In the present embodiment, the mixture is pressed to form a pelletized fuel at a preferred ambient temperature of 80 degrees Celsius or more, and a plurality of derivative particulate fuels are produced by continuous compression. In the present embodiment, the increase in the ambient temperature during the granulation process melts the protein contained in the biological sludge and the lignin contained in the raw material, and solidifies after cooling to form a cemented state, and has an adhesive effect. In order to make the derived particulate fuel denser and have better particle fastness, the mixture can be pelletized without additional adhesive. Of course, in other embodiments, some adhesives may be added during the granulation process to aid in the formation of the granules and to increase the particle fastness.
於另一些實施例中,生質物可為草本植物,如稻稈、狼尾草、培地茅、玉米稈或芒草,且生物污泥係取自於污水處理廠,藉以製造本案之生質物混合生物污泥之衍生顆粒燃料。由於草本生質物相較於生物污泥亦具有高熱值低灰分的性質,因此,可藉由將生質物混入生物污泥,提高製得之衍生顆粒燃料的熱值,同時降低灰分的比例。 In other embodiments, the biomass may be a herbaceous plant, such as rice straw, pennisetum, medusa, corn stalk or miscanthus, and the biological sludge is taken from a sewage treatment plant to produce a hybrid organism of the present invention. Sludge derived pellet fuel. Since the herbaceous biomass has a high calorific value and a low ash property as compared with the biological sludge, the calorific value of the produced derivative pellet fuel can be improved by mixing the biomass into the biological sludge, and the proportion of the ash can be reduced.
根據本案之構想,本案亦提供一種生質物混合生物污泥之衍生顆 粒燃料,其包含生質物以及熱值介於2400卡/克至3900卡/克的生物污泥,其中生物污泥與生質物混合為一混合物料,且該混合物料係壓製為複數個衍生顆粒燃料。本案之生質物混合生物污泥之衍生顆粒燃料之組成、配比及其特性已於前述,於此不再贅述。 According to the concept of this case, the case also provides a derivative of bio-mixed biological sludge. a granular fuel comprising a biomass and a biological sludge having a calorific value of from 2400 calories to 3900 calories per gram, wherein the biological sludge and the biomass are mixed into a mixture, and the mixture is pressed into a plurality of derived particles fuel. The composition, ratio and characteristics of the derived particulate fuel of the biomass-mixed biological sludge in the present invention have been described above and will not be described herein.
綜上所述,本案提供一種生質物混合生物污泥之衍生顆粒燃料及其製法,其可以較低成本之方式使生物污泥大幅減量去化,並使廢棄物燃料化,達到有效的資源再利用。此外,本案之衍生顆粒燃料及其製法可製成單位熱能較高且便於儲藏與運送之固態衍生燃料,以作為各種加熱設備之替代燃料使用,並可達到節能減碳之目的。再則,本案之衍生顆粒燃料及其製法可依使用需求製成各種具較高熱值及較低灰份之衍生顆粒燃料,且其製造成本低,製造過程之能源消耗較低,易於量產。 In summary, the present invention provides a derivative particulate fuel of biomass mixed biological sludge and a preparation method thereof, which can substantially reduce the amount of biological sludge in a lower cost manner, and fuel the waste to achieve an effective resource. use.
