關於對流動性的處理對象物加熱乾燥的系統,企盼能更加削減乾燥所需的時間及費用。 The system for heating and drying the object to be treated for fluidity is expected to further reduce the time and cost required for drying.

本發明的一態樣為一種系統,具有:第1槽,其將流動性的處理對象物暫時地收進並進行預熱;第2槽,其收進藉由前述第1槽所預熱之處理對象物並進行加熱乾燥處理;及熱回收單元,其利用從前述第2槽排出之排氣的熱來加熱前述第1槽。 An aspect of the present invention provides a system including: a first tank that temporarily collects and preheats a fluid processing object; and a second tank that is preheated by the first tank The object to be processed is subjected to heat drying treatment, and the heat recovery unit heats the first tank by heat of the exhaust gas discharged from the second tank.

在對第2槽中之流動性的處理對象物進行乾燥的過程中,從第2槽排出含有水蒸氣的排氣,此排氣通過集塵機等而被廢棄到外界。該系統中,於第2槽的上游設置將在第2槽乾燥的處理對象物暫時地收進之第1槽,利用第2槽的排氣的熱(排熱)加熱第1槽,將在第1槽預熱後的處理對象物供給至第2槽。利用第2槽的排熱對暫時地儲存於第2槽上游的第1槽之處理對象物進行加熱(預熱),藉此可削減乾燥所需的費用。 In the process of drying the fluidity of the object to be treated in the second tank, the exhaust gas containing water vapor is discharged from the second tank, and the exhaust gas is discarded to the outside through a dust collector or the like. In this system, the first tank in which the object to be processed which is dried in the second tank is temporarily taken in the upstream of the second tank is provided, and the first tank is heated by the heat (exhaust heat) of the exhaust gas in the second tank. The object to be treated after the first tank is preheated is supplied to the second tank. By heating (preheating) the object to be treated which is temporarily stored in the first tank upstream of the second tank by the heat removal in the second tank, the cost required for drying can be reduced.

又,藉由將第1槽中預熱的處理對象物供給至第2槽,可縮短乾燥所需的時間。而且,藉由在第1槽中預熱處理對象物可提升處理對象物的流動性。因此,處理對象物在從第1槽供給至第2槽之際的搬送變得容易,能以配管、螺旋式送料機等低成本的系統將處理對象物移送至第2槽。 Moreover, by supplying the object to be processed which is preheated in the first tank to the second tank, the time required for drying can be shortened. Further, the fluidity of the object to be processed can be improved by preheating the object in the first groove. Therefore, the conveyance of the object to be processed is facilitated when it is supplied from the first tank to the second tank, and the object to be processed can be transferred to the second tank by a low-cost system such as a pipe or a screw feeder.

較佳為,第1槽包含具備第2槽的1批次份量的容量之計量槽。在使用第2槽的加熱乾燥處理是批次作業的情況,透過預熱1批次份量的容量的計量槽,利用第2槽的排熱可將下個批次份量的處理對象物集中加熱。因此,可提升排熱的利用效率。又,雖處理對象物高溫長時間保持時容易發生腐敗等之問題,但藉由加熱1批次份量的處理對象物亦可抑制那種問題的發生。 Preferably, the first tank includes a metering tank having a capacity of one batch of the second tank. In the case where the heat drying treatment using the second tank is a batch operation, the processing target of the next batch size can be collectively heated by the heat removal of the second tank by preheating the metering tank of the capacity of one batch. Therefore, the utilization efficiency of the exhaust heat can be improved. In addition, although the object to be processed is likely to be spoiled when the temperature of the object to be treated is high for a long period of time, it is possible to suppress the occurrence of such a problem by heating the object to be processed in one batch.

第2槽的排氣包含水蒸氣及各式各樣的成分。因此,較佳為,熱回收單元包含利用第2槽之排氣的熱生成預熱第1槽的溫水之熱交換單元。可抑制在對第1槽進行預熱的配管系統等發生所謂腐蝕、氣孔堵塞之問題。 The exhaust gas in the second tank contains water vapor and various components. Therefore, it is preferable that the heat recovery unit includes a heat exchange unit that uses the heat of the exhaust gas of the second tank to preheat the warm water of the first tank. It is possible to suppress the occurrence of so-called corrosion and pore clogging in a piping system that preheats the first tank.

較佳為,該系統具有在第2槽內使葉片旋轉並攪拌之攪拌單元,第2槽包含排氣口,其排出排氣且第2槽內的開口是朝向葉片的旋轉方向。由於排氣口的開口是面向依攪拌單元之旋轉在第2槽內生成之流動方向的下游側,故因流動的處理對象物乾燥而產生的固體物、粉末、塵等難以進入排氣口。可降低從排氣口回收的排氣所含之粉末等固體物的量,熱回收單元的設計變容易。 Preferably, the system has a stirring unit that rotates and agitates the vanes in the second tank, and the second tank includes an exhaust port that exhausts the exhaust gas and the opening in the second tank faces the rotation direction of the vane. Since the opening of the exhaust port faces the downstream side in the flow direction generated in the second groove by the rotation of the agitation unit, solid matter, powder, dust, and the like which are generated by the drying of the object to be processed are hard to enter the exhaust port. The amount of solid matter such as powder contained in the exhaust gas recovered from the exhaust port can be reduced, and the design of the heat recovery unit becomes easy.

較佳為,該系統更具有使蒸氣斷續地吹出至前述排氣口的前述第2槽內的開口近旁之注入單元。第2槽的加熱,典型的是使用蒸氣,特別是飽和或接近飽和或過飽和的狀態之生蒸氣。在該情況,較佳為,系統更具有蒸氣供給單元,其供給加熱用蒸氣而從外側以蒸氣對第2槽進行加熱,注入單元吹出加熱用蒸氣的一部份。藉由將蒸氣朝排氣口的 開口近旁放出,使開口近旁的濕度暫時地提高,可抑制乾燥或正乾燥中的粉末(塵)連同氣體一起被排出。 Preferably, the system further has an injection unit that intermittently blows the vapor to the vicinity of the opening in the second groove of the exhaust port. The heating of the second tank is typically the use of steam, particularly a saturated or near saturated or supersaturated state of the vapor. In this case, it is preferable that the system further includes a vapor supply unit that supplies the steam for heating and heats the second tank from the outside with steam, and the injection unit blows a part of the steam for heating. By venting the vapor toward the exhaust The opening is released in the vicinity of the opening, so that the humidity in the vicinity of the opening is temporarily increased, and it is possible to suppress the powder (dust) in the drying or the drying from being discharged together with the gas.

攪拌單元的一例為,包含有:通過第2槽的中心之旋轉軸;從旋轉軸向水平方向突出的複數個第1臂;可對複數個第1臂各自裝卸地安裝的第2臂;及安裝於第2臂的前端且順著第2槽的內壁之弧狀的攪拌葉片。第2臂亦可含有和攪拌葉片呈三角形地安裝之2根副臂。第2臂及攪拌葉片會有因攪拌處理對象物而緩慢被切削且因處理對象物的狀態而偶有變形的情形。在那種情況時,可容易地交換第2臂及攪拌葉片。 An example of the agitation unit includes: a rotation axis that passes through a center of the second groove; a plurality of first arms that protrude horizontally from the rotation axis; and a second arm that is detachably attached to the plurality of first arms; An agitating blade attached to the distal end of the second arm and following the inner wall of the second groove. The second arm may also include two jibs that are triangularly mounted with the agitating blades. The second arm and the agitating blade may be slowly cut by the object to be agitated, and may be deformed occasionally due to the state of the object to be processed. In that case, the second arm and the stirring blade can be easily exchanged.

較佳為,攪拌單元的通過第2槽的中心之旋轉軸係被以對第2槽的下側可上下地滑動之狀態支承,在被從第2槽的上方懸吊的狀態下由驅動單元旋轉驅動。藉由將旋轉軸以可對第2槽的下側滑動的狀態支承,即便是施加於旋轉軸的負荷大的情況亦可使之穩定地旋轉,且可對應第2槽的熱膨脹。 Preferably, the rotation axis of the center of the second groove is supported by the lower side of the second groove so as to be vertically slidable, and the drive unit is suspended by the upper side of the second groove. Rotate the drive. By supporting the rotating shaft in a state in which the lower side of the second groove can be slid, even when the load applied to the rotating shaft is large, the rotating shaft can be stably rotated, and the thermal expansion of the second groove can be performed.

該系統亦可更具有分類單元,其從廢棄物分類含有包裝材料的異物並將流動性的處理對象物向第1槽供給。從食品等之廢棄物的分類到乾燥處理為止,能以1個系統來處理。 The system may further include a sorting unit that sorts the foreign matter containing the packaging material from the waste and supplies the fluidized object to be treated in the first tank. It can be processed by one system from the classification of wastes such as foods to drying treatment.

本發明的其他態樣之一為,使用對流動性的處理對象物進行乾燥的系統來製造乾燥物之方法。該系統系統包含:第1槽,其將處理對象物暫時地收進並進行預熱;第2槽,其收進藉由第1槽所預熱之處理對象物並進行加熱乾燥 處理;及熱回收單元,其回收含有從第2槽排出的水蒸氣之排氣的熱,該方法包含以下步驟。 One of the other aspects of the present invention is a method of producing a dried product using a system for drying a fluidity-treated object. The system system includes a first tank that temporarily collects and preheats the object to be processed, and a second tank that collects the object to be heated by the first tank and heats and dries it. And a heat recovery unit that recovers heat of the exhaust gas containing water vapor discharged from the second tank, the method comprising the following steps.

1.利用第2槽對處理對象物進行乾燥,且利用藉熱回收單元所回收的排熱來加熱前述第1槽。 1. The object to be processed is dried by the second tank, and the first tank is heated by the heat of exhaustion recovered by the heat recovery unit.

2.使第2槽內藉由對處理對象物進行加熱乾燥所製造之乾燥物從前述第2槽排出。 2. The dried product produced by heating and drying the object to be treated in the second tank is discharged from the second tank.

3.使預熱的處理對象物從第1槽移動至第2槽。 3. The preheated object to be processed is moved from the first tank to the second tank.

圖1係顯示廢棄物處理系統的概略構成之方塊圖。該廢棄物處理系統(處理系統)1係將食品廢棄物,例如袋裝的家庭垃圾、從食品工場排出的廚房垃圾等之原材料(廢棄物)2,分成可再生成堆肥、飼料等作利用的分類物4、難再利用的樹脂製袋及塑膠托盤等之異物3,將分類物4作為再生成物5予以輸出的系統。食品殘渣等之可再利用的物質最初被粉碎、加水等並被分類(分離)成具流動性狀態之物(分類 物、流動物)4後,使之乾燥而轉換成堆肥、飼料等之再生成物(乾燥物)5。 Fig. 1 is a block diagram showing a schematic configuration of a waste disposal system. The waste disposal system (treatment system) 1 divides raw materials (waste) 2 such as food waste, such as packaged household waste, kitchen waste discharged from a food factory, into reusable compost, feed, etc. A classification system 4, a resin bag made of a resin that is difficult to reuse, and a foreign matter 3 such as a plastic tray, and a system in which the classified product 4 is output as the regenerated product 5. Reusable substances such as food residues are initially pulverized, watered, etc., and classified (separated) into a fluid state (classification) After the object or the fluid) 4, it is dried and converted into a reconstituted product (dry matter) 5 of compost, feed, or the like.

攪拌單元430包含:葉輪軸432,其沿著爐身410的中心軸配置;驅動單元480,其驅動葉輪軸432;及複數個葉片單元431,其等藉由葉輪軸432而在爐身410的內部411被驅動旋轉。驅動單元480係搭載於爐身410的上板413之上,包含有:馬達482;齒輪單元481,其將馬達482的動力傳遞至葉輪軸432;及軸承單元485,其支承葉輪軸432使之可對爐身410旋轉。葉輪軸432的上下方向之荷重(推力)係由齒輪單元481所支承。亦即,葉輪軸432係以藉齒輪單元481從上方懸吊的狀態進行旋轉。亦可作成葉輪軸432係其荷重是利用止推軸承等之別的方法由爐身410的上方承接,且葉輪軸432透過爐身410的熱膨脹而被吊起。 The agitation unit 430 includes an impeller shaft 432 disposed along a central axis of the furnace body 410, a drive unit 480 that drives the impeller shaft 432, and a plurality of blade units 431 that are at the furnace body 410 by the impeller shaft 432. The inner portion 411 is driven to rotate. The driving unit 480 is mounted on the upper plate 413 of the shaft 410 and includes a motor 482, a gear unit 481 that transmits power of the motor 482 to the impeller shaft 432, and a bearing unit 485 that supports the impeller shaft 432. The shaft 410 can be rotated. The load (thrust) in the vertical direction of the impeller shaft 432 is supported by the gear unit 481. That is, the impeller shaft 432 is rotated in a state of being suspended from above by the gear unit 481. The impeller shaft 432 may be formed such that the load is received from above the shaft 410 by a method such as a thrust bearing, and the impeller shaft 432 is lifted by thermal expansion of the shaft 410.

葉輪軸432係經由油封486貫通上板413且橫亙爐身410的內部411大致整體地上下延伸,葉輪軸432的下端432a會到達爐身410之底板414的正上,但不與底板414接觸。在底板414安裝沿著爐身410的中心軸朝上方延伸的支承杆439。支承杆439係貫通中空的葉輪軸432之下端432a並插入葉輪軸432的內部,從葉輪軸內部以葉輪軸432可對支承杆439上下地滑動的狀態支承著葉輪軸432。 The impeller shaft 432 penetrates the upper plate 413 via the oil seal 486 and extends substantially vertically up and down the inner portion 411 of the furnace body 410. The lower end 432a of the impeller shaft 432 reaches the bottom plate 414 of the shaft 410, but does not contact the bottom plate 414. A support rod 439 extending upward along the central axis of the shaft 410 is mounted on the bottom plate 414. The support rod 439 penetrates the lower end 432a of the hollow impeller shaft 432 and is inserted into the inside of the impeller shaft 432. The impeller shaft 432 is supported by the impeller shaft 432 from the inside of the impeller shaft 432 so that the support rod 439 can slide up and down.

因此,葉輪軸432,係以上端部於軸承單元485不在水平方向移動且下端藉由支承杆439而不在水平方向移動的方式支承,沿著爐身410的中心軸在水平方向旋轉。且葉輪軸432的下端對支承杆439上下地滑動。因此,葉輪軸432係以上端被驅動單元480懸吊的狀態進行旋轉。當爐身410被蒸氣加熱而在上下方向產生熱膨脹時,葉輪軸432會因為驅動單元480而被朝上方拉伸,但葉輪軸432的下端會依支承杆439進行滑動,不會從支承杆439脫落。即便爐身410熱膨脹,葉輪軸432的上下端還是被支承在爐身410的中心軸的位置,藉由驅動單元480穩定地旋轉。 Therefore, the impeller shaft 432 is supported such that the upper end portion of the impeller shaft 485 does not move in the horizontal direction and the lower end is not moved in the horizontal direction by the support rod 439, and rotates in the horizontal direction along the central axis of the shaft 410. The lower end of the impeller shaft 432 slides up and down the support rod 439. Therefore, the impeller shaft 432 is rotated in a state in which the upper end is suspended by the drive unit 480. When the furnace body 410 is heated by steam to cause thermal expansion in the up and down direction, the impeller shaft 432 is pulled upward by the drive unit 480, but the lower end of the impeller shaft 432 is slid by the support rod 439 without coming from the support rod 439. Fall off. Even if the shaft 410 is thermally expanded, the upper and lower ends of the impeller shaft 432 are supported at the position of the central axis of the shaft 410, and are stably rotated by the driving unit 480.

因此,即便乾燥中的分類物4之負荷施加於葉片單元431,葉片單元431仍不會左右地振動,能使葉片單元431以接近於側壁412的狀態旋動。因此,能以葉片單元431將緊貼於側壁412之乾燥中的分類物4往上刮(刮落),能抑制側壁412因被分類物4所包覆而使熱傳導率、乾燥效率降低的情形。因此,可隔著側壁412有效率地加熱分類物4。 Therefore, even if the load of the classified product 4 in the dry state is applied to the blade unit 431, the blade unit 431 does not vibrate left and right, and the blade unit 431 can be rotated in a state close to the side wall 412. Therefore, the blade unit 431 can scrape (scrape) the sorted material 4 that is in contact with the drying of the side wall 412, and can suppress the thermal conductivity and the drying efficiency of the side wall 412 being covered by the classified object 4. . Therefore, the sorter 4 can be efficiently heated across the side wall 412.

在葉輪軸432,複數個葉片單元431在葉輪軸432上下方向呈螺旋狀地安裝,當葉輪軸432一旋轉時葉片單元431亦同時旋轉。本例中,從上方觀看是朝順時鐘方向11旋轉,但亦可設計成朝逆時鐘方向旋轉。各個葉片單元431包含:第1臂434,從葉輪軸432朝周壁412於徑向(水平方向)延伸的方式安裝在葉輪軸432;第2臂435,在第1臂434前端呈複數分支地延伸;及板狀刮板(上刮葉片)436,安裝在第2臂435的前端。 In the impeller shaft 432, a plurality of blade units 431 are spirally mounted in the vertical direction of the impeller shaft 432, and the blade unit 431 also rotates as the impeller shaft 432 rotates. In this example, it is rotated in the clockwise direction 11 as viewed from above, but may be designed to rotate in the counterclockwise direction. Each of the blade units 431 includes a first arm 434 that is attached to the impeller shaft 432 so as to extend in the radial direction (horizontal direction) from the impeller shaft 432 toward the peripheral wall 412. The second arm 435 extends in a plurality of branches at the distal end of the first arm 434. And a plate-shaped squeegee (upper blade) 436 attached to the front end of the second arm 435.

刮板436係為外側緣順著爐身410的周壁(側壁)412之弧狀的板狀構件,例如為不銹鋼製。刮板436係藉由臂434及435以相對於行進方向(順時鐘方向)11後端是比前端還高的方式對葉輪軸432傾斜安裝。當葉輪軸432一旋轉時,安裝於葉輪軸432的複數個刮板436對除了爐身410的周壁412上方以外的大致全區域進行掃除,藉此可將附著於周壁412之乾燥中的分類物4刮落(上刮)。各個刮板436係例如被安裝成相對於水平方向呈10~15°的角度,以一刮板436掃過的區域與上下的刮板436掃過的區域會一部份重複的方式來設定刮板436的角度及長度。 The squeegee 436 is an arc-shaped plate-like member whose outer edge follows the peripheral wall (side wall) 412 of the shaft 410, and is made of, for example, stainless steel. The squeegee 436 is attached to the impeller shaft 432 by the arms 434 and 435 so as to be higher than the front end with respect to the traveling direction (clockwise direction) 11. When the impeller shaft 432 rotates, the plurality of squeegees 436 attached to the impeller shaft 432 sweep away substantially the entire area except the upper portion of the peripheral wall 412 of the shaft 410, whereby the dry matter attached to the peripheral wall 412 can be sorted. 4 scraping (upper shaving). Each of the squeegees 436 is mounted, for example, at an angle of 10 to 15 degrees with respect to the horizontal direction, and the area swept by a squeegee 436 and the area swept by the upper and lower squeegees 436 are partially scraped. The angle and length of the plate 436.

在刮板436後端的上方安裝有朝上方突出的突起(爪)437。例如,突起437係為相對於旋轉方向(行進方向)11前方的高度較高之梯形板體,可使乾燥且呈塊狀(團狀)的乾燥中之分類物4有效地破碎。因該系統1所處理之對象物而異,亦可為沒有突起437,又,不僅是刮板436的後端,亦可在中間或前端設置複數個突起。 A protrusion (claw) 437 that protrudes upward is attached above the rear end of the squeegee 436. For example, the protrusion 437 is a trapezoidal plate body having a high height in front of the rotation direction (traveling direction) 11, and the dry and block-shaped (packed) dry classification 4 can be effectively broken. Depending on the object to be processed by the system 1, there may be no protrusions 437, and not only the rear end of the squeegee 436, but also a plurality of protrusions may be provided in the middle or at the front end.

支承刮板436的第2臂435係包含從與第1臂434連接之連接部435a分支的複數個副臂435b。本例中的臂435包含呈Y字狀分支的2根副臂435b,利用該等副臂435b於前後複數個位置支承刮板436。因此,能使刮板436的位置及姿勢穩定,能使刮板436接近周壁412並有效率地將分類物4刮落。刮板436因和分類物4接觸有可能磨損消耗、損傷。因此,以對第2臂435可裝卸的方式安裝較為理想。例如,能藉螺栓或螺帽將刮板436安裝於第2臂435,螺栓或螺帽可設 於刮板436的上面、亦可設於下面。由於刮板436的下面與分類物4接觸的機會少,故容易抑制螺栓或螺帽的消耗。 The second arm 435 of the support blade 436 includes a plurality of sub-arms 435b branched from the connection portion 435a connected to the first arm 434. The arm 435 in this example includes two sub-arms 435b branched in a Y-shape, and the sub-arms 435b support the squeegee 436 at a plurality of positions in front and rear. Therefore, the position and posture of the blade 436 can be stabilized, and the blade 436 can be brought close to the peripheral wall 412 and the sorting object 4 can be scraped off efficiently. The squeegee 436 may wear and damage due to contact with the sorter 4. Therefore, it is preferable to mount the second arm 435 so as to be attachable and detachable. For example, the squeegee 436 can be attached to the second arm 435 by bolts or nuts, and the bolt or nut can be set. On the upper surface of the squeegee 436, it may be provided below. Since the lower surface of the squeegee 436 has less chance of coming into contact with the sorter 4, it is easy to suppress the consumption of the bolt or the nut.

本例中,再者,以亦能利用螺栓或螺帽對第1臂434進行裝卸的方式安裝第2臂435,可在第2臂435消耗,損傷時進行交換。第1臂434係以120度間距安裝於葉輪軸432。安裝第1臂434的間隔為等間隔即可不限定為120度。又,複數個第1臂434為,以各個複數個刮板436從下側輪流將分類物4上刮並可將分類物4上刮到爐身410上方的方式呈螺旋狀地安裝於葉輪軸432上。 In this example, the second arm 435 is attached so that the first arm 434 can be attached or detached by a bolt or a nut, and the second arm 435 can be consumed and exchanged at the time of damage. The first arm 434 is attached to the impeller shaft 432 at a pitch of 120 degrees. The interval at which the first arm 434 is attached is not equal to 120 degrees. Further, the plurality of first arms 434 are spirally attached to the impeller shaft in such a manner that each of the plurality of squeegees 436 scrapes the sorting material 4 from the lower side and scrapes the sorting material 4 above the shaft 410. On 432.

爐身410內之典型的分類物4之動向為,被複數個刮板436沿著周壁412的內側一邊加熱一邊到達爐身410的上方,順著葉輪軸432朝底壁414落下。在分類物4順著葉輪軸432落下時會因為衝撞分支的第2臂435而粉碎。因此,在爐身410的內部,分類物4一邊被加熱一邊被攪拌及破壞而成為較細的粒子狀或粉狀。在那時,分類物4所含的水分成為水蒸氣6從爐身410被排出。 The movement of the typical classification 4 in the shaft 410 is such that a plurality of squeegees 436 are heated along the inner side of the peripheral wall 412 to reach above the shaft 410, and descend toward the bottom wall 414 along the impeller shaft 432. When the sorter 4 falls down the impeller shaft 432, it is pulverized by the second arm 435 which collides with the branch. Therefore, in the inside of the furnace body 410, the classified object 4 is stirred and broken while being heated to become finer particles or powder. At that time, the moisture contained in the classified material 4 is discharged from the furnace body 410 as the water vapor 6.

爐身410包含收進分類物4之供給口420、及排出含水蒸氣的氣體(排氣)之排氣口460。供給口420及排氣口460包含分別以貫通上板413的方式設置的噴嘴(管台)421及461。排氣管461之面向爐身410的內部之開口462係朝攪拌單元430的旋轉方向,即順時鐘方向11開設。亦可為控制排氣口460的開口462之朝向而在爐身410的上壁413的內側彎曲排氣管461,亦可在上壁413的內側設置面向順時鐘方向11開設開口462之盒狀的構造物。 The furnace body 410 includes a supply port 420 for receiving the classified product 4, and an exhaust port 460 for discharging a gas (exhaust) containing water vapor. The supply port 420 and the exhaust port 460 include nozzles (tube stages) 421 and 461 which are provided to penetrate the upper plate 413, respectively. The opening 462 of the exhaust pipe 461 facing the inside of the furnace body 410 is opened in the direction of rotation of the stirring unit 430, that is, in the clockwise direction 11. The exhaust pipe 461 may be bent inside the upper wall 413 of the furnace body 410 for controlling the direction of the opening 462 of the exhaust port 460, or may be provided on the inner side of the upper wall 413 to open the opening 462 in the clockwise direction 11. Structure.

在爐身410的內部411,因分類物4被加熱而產生水蒸氣6,同時分類物4經乾燥而成的乾燥物5被刮板436捲起成為粉塵。藉由使排氣口460的開口462朝向與刮板436行進方向相同方向,可抑制連同刮板436一起被邊旋轉邊被扒上爐身410的上部之粉狀的乾燥物5侵入到排氣口460,可使主成分為水蒸氣6的流狀體(氣體)從排氣口460排出。 In the interior 411 of the furnace body 410, the water vapor 6 is generated by the classification of the product 4, and the dried product 5 obtained by drying the classified product 4 is rolled up by the squeegee 436 to become dust. By making the opening 462 of the exhaust port 460 in the same direction as the traveling direction of the squeegee 436, it is possible to suppress the powdery dry matter 5 that has been smashed up along the upper portion of the furnace body 410 while being rotated together with the squeegee 436 into the exhaust gas. The port 460 allows a fluid (gas) whose main component is water vapor 6 to be discharged from the exhaust port 460.

而且,在爐身410的排氣口460設有將蒸氣51朝爐身410的內部411吹出的蒸氣注入單元440。本例中,在排氣管461的一部份上設有蒸氣注入用的噴嘴441,建構成可在排氣管461的內部使蒸氣51朝爐身410的內部411吹出。藉由定期地將蒸氣吹向排氣管461的內部,可將蓄積於排氣管461的乾燥物5以加濕的狀態剝離並使之返回爐身410的內部411。因此,可抑制排氣管461因乾燥物5而堵塞及乾燥物5經由蒸氣排出管501被搬送至熱回收單元500的情形。又,在進行乾燥物5之除去時是使用蒸氣51而非空氣,藉此可抑制乾燥物5在乾燥的狀態下被捲起而進到蒸氣排出管501那側的情形。因此,以注入的蒸氣51盡可能是乾燥度低的飽和或過飽和的蒸氣(生蒸氣)較理想。 Further, a steam injection unit 440 that blows the steam 51 toward the inside 411 of the furnace body 410 is provided at the exhaust port 460 of the furnace body 410. In this example, a portion of the exhaust pipe 461 is provided with a nozzle 441 for vapor injection, and the steam 51 is blown toward the inside 411 of the furnace body 410 inside the exhaust pipe 461. By periodically blowing the vapor into the inside of the exhaust pipe 461, the dried product 5 accumulated in the exhaust pipe 461 can be peeled off and returned to the inside 411 of the furnace body 410. Therefore, it is possible to suppress the clogging of the exhaust pipe 461 by the dry matter 5 and the fact that the dried product 5 is transported to the heat recovery unit 500 via the vapor discharge pipe 501. Further, when the drying of the dried product 5 is carried out, the steam 51 is used instead of the air, whereby the dry product 5 can be prevented from being rolled up in a dry state and coming to the side of the vapor discharge pipe 501. Therefore, it is preferable that the injected vapor 51 is as saturated or supersaturated vapor (raw steam) as low as possible.

在爐身410的周壁412的底壁414正上,設有將乾燥物5排出的排出口470。排出口470的一例為噴嘴(管台),亦可為面向爐身410的內部朝下方傾斜者,俾抑制乾燥中的分類物4、乾燥物5的堆積。在排出口470連接有螺旋式送料機(螺旋式輸送機)610,在乾燥中係可利用適當的開閉機構例如閘門或閥事先將排出口470關閉、亦可使螺旋式送料 機610朝和排出方向相反方向旋轉。 Immediately above the bottom wall 414 of the peripheral wall 412 of the shaft 410, a discharge port 470 for discharging the dried product 5 is provided. An example of the discharge port 470 is a nozzle (tube stage), and the inside of the furnace body 410 may be inclined downward, and the accumulation of the classified product 4 and the dried product 5 during drying may be suppressed. A screw feeder (screw conveyor) 610 is connected to the discharge port 470. In the drying, the discharge port 470 can be closed in advance by a suitable opening and closing mechanism such as a gate or a valve, and the screw feed can also be performed. The machine 610 rotates in the opposite direction to the discharge direction.

圖4以流程圖顯示藉處理系統1製造乾燥物5之過程。於步驟901,並列地進行使用分類裝置100的分類處理910、使用乾燥裝置400的乾燥處理940、以及使用計量單元350將分類物4預熱的處理930。在未存在有作為分類處理910的對象之廢棄物2的情況,不進行分類處理910。同樣地,在未存在有作為乾燥處理940的對象之分類物4的情況,不進行乾燥處理940及預熱處理930。 Figure 4 shows, in a flow chart, the process by which the processing system 1 produces the dried product 5. In step 901, the sorting process 910 using the sorting device 100, the drying process 940 using the drying device 400, and the process 930 of preheating the sorter 4 using the metering unit 350 are performed in parallel. In the case where the waste 2 which is the object of the classification process 910 does not exist, the classification process 910 is not performed. Similarly, in the case where the classification 4 which is the object of the drying process 940 does not exist, the drying process 940 and the pre-heat treatment 930 are not performed.

在分類處理910,控制單元800的控制分類裝置之機能810是驅動旋轉葉片120,當流動性的分類物4一儲存於分類裝置100時,螺旋式送料機180將分類物4送往壓送裝置200,壓送裝置200將分類物4送至儲存槽311暫時儲存。 In the sorting process 910, the function 810 of the control sorting device of the control unit 800 drives the rotating blade 120. When the fluidity classification 4 is stored in the sorting device 100, the screw feeder 180 sends the sorting device 4 to the presser device. 200, the pressure feeding device 200 sends the classification 4 to the storage tank 311 for temporary storage.

在乾燥處理940,控制單元800的控制乾燥裝置之機能840是驅動乾燥裝置400的攪拌單元430的驅動單元480,使複數個葉片單元431在藉蒸氣加熱的爐身410中旋轉。藉此使被收進爐身410之流動性(漿狀)的分類物4被加熱乾燥並粉碎而生成乾燥物5。在乾燥處理940,控制單元800定期地操作被設在爐身410的排氣口460之蒸氣注入單元440的電磁閥442,向排氣口460及其近旁注入蒸氣51,以抑制排氣口460被乾燥物5堵塞及乾燥物5流越(carry-over)熱回收單元500之側的情況。 In the drying process 940, the function 840 of the control drying device of the control unit 800 is a drive unit 480 that drives the agitation unit 430 of the drying device 400 to rotate a plurality of blade units 431 in the furnace body 410 heated by steam. Thereby, the fluidity (slurry) classified product 4 that has been taken into the furnace body 410 is dried by heating and pulverized to form a dried product 5. In the drying process 940, the control unit 800 periodically operates the solenoid valve 442 of the vapor injection unit 440 disposed at the exhaust port 460 of the furnace body 410, and injects the steam 51 toward the exhaust port 460 and its vicinity to suppress the exhaust port 460. The object to be dried 5 is clogged and the dried product 5 is carried-over to the side of the heat recovery unit 500.

在預熱處理930,控制單元800的控制計量單元的機能830是使用計量單元350的攪拌裝置362攪拌被收進計量槽361的分類物4。計量槽361係被從熱回收單元500所供 給之溫水9所加熱,以預熱被收進計量槽361之1批次份量的分類物4。在熱回收單元500,使用從乾燥裝置400的爐身410排出之水蒸氣6的熱(排熱)生成溫水9。由於計量槽361中之分類物4的預熱是使用乾燥裝置400的排熱,故可削減運轉成本。藉由將已預熱之分類物4供予乾燥裝置400可降低乾燥裝置400的處理費用及時間。因此,能以低成本生成乾燥物5。 In the preheat treatment 930, the function 830 of the control metering unit of the control unit 800 is agitating the sorting material 4 that is taken into the metering tank 361 using the stirring device 362 of the metering unit 350. The metering tank 361 is supplied from the heat recovery unit 500 The warm water 9 is heated to preheat the classified product 4 which is taken into the batch portion of the measuring tank 361. In the heat recovery unit 500, warm water 9 is generated using heat (exhaust heat) of the water vapor 6 discharged from the furnace body 410 of the drying device 400. Since the preheating of the sorting material 4 in the measuring tank 361 is the exhaust heat using the drying device 400, the running cost can be reduced. The processing cost and time of the drying device 400 can be reduced by supplying the preheated classification 4 to the drying device 400. Therefore, the dried product 5 can be produced at low cost.

在計量槽361中,對乾燥裝置400的1次乾燥處理份量(1批次份量)的分類物4進行預熱。因此,由於在計量槽361中,限定對下個乾燥處理的分類物4進行預熱,故可將分類物4的計量槽361的出口溫度設高。因此,在從乾燥裝置400排出的水蒸氣6沒那麼多的情況,亦可有效率地預熱分類物4,又可確保搬送所需的流動性。雖分類物4經長期間預熱時會有分類物4發酵、腐敗的可能性,但該系統1中,因為是在乾燥處理前利用計量槽361將限於1批次份量之量的分類物4進行預熱,故可防範發生那樣的問題。 In the measuring tank 361, the classified product 4 of the primary drying treatment amount (one batch portion) of the drying device 400 is preheated. Therefore, since the classification 4 of the next drying process is preheated in the metering tank 361, the outlet temperature of the metering tank 361 of the class 4 can be set high. Therefore, in the case where there is not much water vapor 6 discharged from the drying device 400, the classification 4 can be efficiently preheated, and the fluidity required for transportation can be ensured. Although the classification 4 may have a possibility of fermentation and spoilage of the classified product 4 when it is preheated for a long period of time, in the system 1, the classification 4 is limited to the amount of one batch by using the measuring tank 361 before the drying treatment. Preheating can prevent such problems from occurring.

又,藉由在計量槽361預熱分類物4可提高分類物4的流動性,變得容易從計量槽361朝爐身410搬送分類物4。因此,可藉由簡單的配管、輸送機將流動性的分類物4從計量槽361朝爐身410供給。 Moreover, by preheating the sorted product 4 in the measuring tank 361, the fluidity of the sorting material 4 can be improved, and the sorting material 4 can be easily conveyed from the measuring tank 361 toward the furnace body 410. Therefore, the fluidity classification 4 can be supplied from the measuring tank 361 to the furnace body 410 by a simple piping or conveyor.

於步驟902當乾燥裝置400中的乾燥處理一結束時,於步驟903開動搬送單元600的螺旋式送料機610從爐身410排出乾燥物5。於步驟904,操作供給閥380,將於計量槽361中預熱的分類物4收進爐身410作為下個乾燥處理的處理對象物。於步驟905,驅動攪拌單元430,再度開始乾燥 處理。當自計量槽361排出分類物4時,於步驟906,操作閥330而從儲存槽311將下個乾燥處理的分類物4收進計量槽361,開始預熱。 In step 902, when the drying process in the drying device 400 is completed, the screw feeder 610 that starts the conveying unit 600 in step 903 discharges the dry matter 5 from the furnace body 410. In step 904, the supply valve 380 is operated, and the classified product 4 preheated in the measuring tank 361 is taken into the furnace body 410 as a processing target for the next drying process. In step 905, the stirring unit 430 is driven to start drying again. deal with. When the sorting material 4 is discharged from the metering tank 361, in step 906, the valve 330 is operated to collect the next dried processed sorting material 4 from the storage tank 311 into the measuring tank 361, and the preheating is started.

此外,上述係以包含有分類裝置100、壓送裝置200、乾燥裝置400等之處理系統1為例作說明本發明,但處理系統1亦可為將在其他處理系統已分類的分類物4收進儲存槽311,以計量單元350預熱,再以乾燥裝置400生成乾燥物5的系統。又,處理系統1亦可為依藉由乾燥裝置400再生之物(再生物、乾燥物)5及其用途而具有上述的裝置以外更含有脫脂裝置等。 Further, the present invention is described by taking the processing system 1 including the sorting device 100, the pressurizing device 200, the drying device 400, and the like as an example, but the processing system 1 may also be a sorted product 4 that has been classified in other processing systems. The storage tank 311 is preheated by the metering unit 350, and the drying apparatus 400 is used to generate a system of the dried material 5. Further, the treatment system 1 may include a degreasing device or the like in addition to the above-described devices depending on the material (regenerant, dry matter) 5 regenerated by the drying device 400 and its use.
