Description
本發明係有關於一種熱散裝物品用冷卻設備。The present invention relates to a cooling device for a heat-dissipating article.
在冷卻諸熱散裝物品(例如燒結鐵礦)時盡可能有效地利用與其同時所生成之廢熱的嘗試。Attempts to utilize waste heat generated at the same time as efficiently when cooling hot bulk items, such as sintered iron ore.
呈圓形井下熱交換器或圓形刮面熱交換器型式之叉流式熱交換器係屬先前技藝。然而，在圓形井下熱交換器之情形中，隨著廢氣溫度持續下降，使得廢熱回收將被限制在此熱交換器的前三分之一。在圓形刮面熱交換器之情形中，將有熱與暖廢氣之混合存在，但其溫度基本上不可能達到如最高時之情形，以致使得廢熱回收之效率也被降低。A prior art is a cross-flow heat exchanger of the type of a circular downhole heat exchanger or a circular scraper heat exchanger. However, in the case of a circular downhole heat exchanger, as the exhaust gas temperature continues to decrease, waste heat recovery will be limited to the first third of this heat exchanger. In the case of a circular scraped surface heat exchanger, there will be a mixture of hot and warm exhaust gases, but the temperature is substantially impossible to reach as high as possible, so that the efficiency of waste heat recovery is also reduced.
本發明之目的在於，藉由諸熱散裝物品於冷卻期間所生成之廢熱可被更有效利用之手段，以創造許多可行性。It is an object of the present invention to create a number of possibilities by utilizing the waste heat generated by the heat-dissipating articles during cooling to be more effectively utilized.
此目地係經由一種具有如申請專利範圍第1項中所述特徵之熱散裝物品用冷卻設備而達成。本發明中所請求之冷卻設備的其他有利發展則係申請專利範圍第2至9項附屬項之目的。This object is achieved by a cooling apparatus for a heat-dissipating article having the features recited in claim 1 of the patent application. Other advantageous developments of the cooling apparatus claimed in the present invention are for the purposes of the sub-items 2 to 9 of the patent application.
一種熱散裝物品用冷卻設備將如本發明中所請求般被發展成使得A cooling device for hot bulk articles will be developed as requested in the present invention such that
- 此冷卻設備包括一具有一垂直主軸之冷卻塔，而諸熱散裝物品在此冷卻塔中係藉由一氣流被冷卻，- the cooling device comprises a cooling tower having a vertical main axis, and the hot bulk items are cooled in the cooling tower by a gas flow,
- 此冷卻設備具有一供應裝置，而諸熱散裝物品藉由此供應裝置從上方灌注至冷卻塔內，使諸熱散裝物品可堆置於該冷卻塔中，- the cooling device has a supply device, and the heat-dissipating articles are poured into the cooling tower from above by the supply device, so that the heat-dissipating articles can be stacked in the cooling tower,
- 此冷卻設備具有一移除裝置，而處於冷狀態下之諸散裝物品藉由此移除裝置從冷卻塔之底部移除，以便使餘留在該冷卻塔中之諸散裝物品可向下地滑出，- the cooling device has a removal device, and the bulk items in the cold state are removed from the bottom of the cooling tower by the removal device so that the bulk items remaining in the cooling tower can slide down Out,
- 此冷卻設備具有一送氣裝置，而氣流藉由此送氣裝置被輸送通過冷卻塔，- the cooling device has a gas supply device, and the gas flow is conveyed through the cooling tower by the gas supply device
- 此冷卻設備具有一帶離裝置，而氣流藉由此帶離裝置被帶離冷卻塔，- the cooling device has a take-off device, and the air flow is carried away from the cooling tower by the take-off device,
- 複數個氣流引導手段被配置在冷卻塔中，而諸氣流引導手段從複數個被配置在該塔外壁中之入口處起徑向地向內延伸至該主軸，a plurality of airflow guiding means disposed in the cooling tower, and the airflow guiding means extending radially inward from the plurality of inlets disposed in the outer wall of the tower to the main shaft,
- 諸氣流引導手段被實施成細長型引導手段，其當朝各自之延伸方向觀看時在其長度上具有複數個可供氣流用之出口，以致使此氣流可被引入位於冷卻塔中之諸熱散裝物品內，- the air flow guiding means are embodied as elongated guiding means which, when viewed in the respective extension directions, have a plurality of outlets for the air flow over their length, so that the air flow can be introduced into the heat in the cooling tower In bulk goods,
- 在朝該主軸之方向觀看時，諸氣流引導手段被配置在冷卻塔之中央區域中，且該帶離裝置被配置在冷卻塔之上部區域中，以致使此氣流從底部至頂部地橫貫位於此冷卻塔中之諸熱散裝物品。- when viewed in the direction of the main shaft, the air flow guiding means are arranged in a central region of the cooling tower, and the stripping device is arranged in the upper region of the cooling tower such that the air flow traverses from bottom to top Hot bulk items in this cooling tower.
此發展在於達成：氣流並非以交叉流而是以反向流橫貫諸熱散裝物品。因此不可能再有熱與暖廢氣之混合。This development consists in achieving that the airflow does not traverse the hot bulk items in a reverse flow but in a reverse flow. Therefore, it is impossible to mix hot and warm exhaust gases.
較佳的是，諸氣流引導手段相對於水平形成一傾斜角度，以使此諸氣流引導手段可向上傾斜至該主軸。此發展進一步優化廢熱利用之效率。此在，如果此傾斜角度被選定成大約與諸熱散裝物品相對於水平所形成之散裝物品角度尤其可起作用。因此，此傾斜角度較佳地係介於20°與45°之間，且大部分情形係介於25°與35°之間。Preferably, the airflow guiding means form an oblique angle with respect to the horizontal so that the airflow guiding means can be inclined upward to the main shaft. This development further optimizes the efficiency of waste heat utilization. Thus, it is particularly useful if the angle of inclination is selected to be approximately the angle of the bulk article formed relative to the horizontal of the heat-bulk articles. Therefore, the angle of inclination is preferably between 20 and 45, and in most cases between 25 and 35.

諸氣流引導手段較佳的是延伸直至主軸處，或直至一被配置在此主軸上之轂部處。於此達成：諸熱散裝物品實際上在冷卻塔的整個橫截面上可被氣流橫貫並冷卻。Preferably, the airflow guiding means extend up to the main shaft or up to a hub disposed on the main shaft. It is achieved here that the hot bulk items are actually traversed and cooled by the air flow over the entire cross section of the cooling tower.
帶離裝置較佳的是被配置在該塔外壁中。此發展在於達成：可在無需考量此帶離裝置之發展下設計該供應裝置。Preferably, the strapping device is disposed in the outer wall of the tower. This development is achieved by designing the supply device without the need to consider the development of the strip device.
在本發明之一較佳發展中，此供應裝置係呈一旋轉導槽之形式。此發展達成使諸熱散裝物品在冷卻塔之截面面積上有更好之分佈。In a preferred development of the invention, the supply means is in the form of a rotating channel. This development has resulted in a better distribution of the hot bulk items in the cross-sectional area of the cooling tower.
較佳的是，此冷卻設備被發展成使得：Preferably, the cooling device is developed such that:
- 冷卻塔被配置在一建築物中，而此建築物之諸側壁從底部起延伸直至諸入口上方處，- the cooling tower is arranged in a building, and the side walls of the building extend from the bottom up to above the entrances,
- 移除裝置被配置在此建築物之內部，以便使自冷卻塔處移除之諸散裝物品被安置在此建築物之內部，- a removal device is disposed inside the building such that bulk items removed from the cooling tower are placed inside the building,
- 此冷卻設備具有一連續式輸送裝置，則自冷卻塔中移除之諸散裝物品可藉由此連續式輸送裝置被帶離該建築物，- the cooling device has a continuous conveyor, whereby the bulk items removed from the cooling tower can be carried away from the building by means of the continuous conveyor
- 此連續式輸送裝置具有多個槽狀容器，其在相對於輸送方向橫向觀看時具有一容器截面，而在朝此輸送方向觀看時則具有一容器長度，- the continuous conveyor has a plurality of trough-like containers having a cross-section of the container when viewed transversely with respect to the transport direction and a length of the container when viewed in the direction of transport,
- 諸容器經由兩個被實施成隧道形式之通道區域而從該建築物露出並進入該建築物內，並且- the containers are exposed from the building and into the building via two passage areas that are embodied in the form of tunnels, and

此發展在該送氣裝置被實施成風扇時尤其有利。此風扇在於達成使該氣流之洩漏損失最小化。This development is particularly advantageous when the air supply device is implemented as a fan. This fan is designed to minimize leakage losses from the gas stream.
其它優點與細節可藉由下列示範性實施例之說明以及配合參照所附圖式而被提出。Other advantages and details can be derived from the following description of exemplary embodiments and the accompanying drawings.
如第1圖所示，一種用於冷卻熱散裝物品1(例如小顆粒之燒結鐵礦)之冷卻設備具有一配備有一垂直主軸3之冷卻塔2。此諸熱散裝物品1係藉由氣流4而被冷卻於冷卻塔2中。As shown in Fig. 1, a cooling apparatus for cooling a heat-dissipating article 1 (e.g., small-sized sintered iron ore) has a cooling tower 2 equipped with a vertical main shaft 3. The heat-dissipating articles 1 are cooled in the cooling tower 2 by the air stream 4.
此冷卻設備具有一供應裝置5。諸熱散裝物品1藉由供應裝置5而從上方被灌注至冷卻塔2內。此乃意謂此諸熱散裝物品1會被堆積在冷卻塔2中。This cooling device has a supply device 5. The heat-dissipating articles 1 are poured into the cooling tower 2 from above by the supply device 5. This means that the hot bulk items 1 are stacked in the cooling tower 2.
對應於第1圖中所示，供應裝置5可被實施成一以預定速度n而轉動之旋轉導槽。速度n通常係相當低的。例如，倘若供應裝置5被發展成一旋轉導槽，則速度n可在0.25 rev/min(轉數/分鐘)至1 rev/min間之範圍內。Corresponding to that shown in Fig. 1, the supply device 5 can be implemented as a rotary guide that rotates at a predetermined speed n. The speed n is usually quite low. For example, if the supply device 5 is developed into a rotating channel, the speed n can range from 0.25 rev/min (revolutions per minute) to 1 rev/min.
成為一旋轉導槽之設計意謂諸熱散裝物品1較佳的係分布在冷卻塔2之(水平)橫截面上。然而，可由供應裝置5藉以分布諸熱散裝物品1之有效半徑r，通常係顯著小於冷卻塔2之半徑R。具體而言，此由供應裝置5藉以分布諸熱散裝物品1之有效半徑r最大係冷卻塔2之半徑R的30%。在大部分情形中，所達數值甚至僅在10%與25%之間。因此，一頂錐被形成於塔外壁6(亦即冷卻塔2之垂直或大致垂直壁)附近。此頂錐具有一典型之散裝物品角度α。通常，此散裝物品角度α(取決於諸散裝物品1)係介於大約30°與大約38°之間。The design of a rotating guide means that the heat-dissipating articles 1 are preferably distributed over the (horizontal) cross section of the cooling tower 2. However, the effective radius r of the heat-dissipating articles 1 can be distributed by the supply device 5, typically significantly less than the radius R of the cooling tower 2. Specifically, the effective radius r of the heat-dissipating articles 1 distributed by the supply device 5 is at most 30% of the radius R of the cooling tower 2. In most cases, the value is even between 10% and 25%. Thus, a cone is formed adjacent the outer wall 6 of the tower (i.e., the vertical or substantially vertical wall of the cooling tower 2). This top cone has a typical bulk item angle a. Typically, this bulk item angle a (depending on the bulk item 1) is between about 30° and about 38°.
此外，此冷卻設備具有一移除裝置7。諸散裝物品1藉由此移除裝置7而被從冷卻塔2之底部移除。此乃意謂餘留在冷卻塔2中之諸散裝物品1會向下地滑出。此移除裝置7可被實施成一能以圓形方式被移動之推台。Furthermore, this cooling device has a removal device 7. The bulk items 1 are removed from the bottom of the cooling tower 2 by means of the removal device 7. This means that the bulk items 1 remaining in the cooling tower 2 will slide downward. This removal device 7 can be implemented as a push table that can be moved in a circular manner.
此冷卻設備亦具有一送氣裝置8。氣流4經由此送氣裝置8被輸送通過冷卻塔2。送氣裝置8較佳地被實施成一風扇。然而，原則上亦可成為一抽吸裝置。This cooling device also has a gas supply device 8. The gas stream 4 is conveyed through the cooling tower 2 via this gas supply device 8. The air supply device 8 is preferably embodied as a fan. However, in principle, it can also be a suction device.
此冷卻設備亦具有一帶離裝置9。氣流4藉由此帶離裝置9被帶離冷卻塔2。This cooling device also has a strapping device 9. The gas stream 4 is carried away from the cooling tower 2 by means of the stripping device 9.
當諸散裝物品1被供應至冷卻塔2時，這些物品是熱的。此時典型之溫度達到900℃。當諸散裝物品1從冷卻塔2被移除時，這些物品是(相當)冷的。此時典型之溫度係介於70℃至150℃之間。諸熱散裝物品1之冷卻大致係藉由流經冷卻塔2之氣流4而被執行。因此，氣流4係以冷的狀態(溫度通常等於周遭溫度)被引至冷卻塔2中，且係以熱的狀態(溫度通常介於600℃至800℃之間)自冷卻塔2處被帶離。When the bulk items 1 are supplied to the cooling tower 2, these items are hot. At this time, the typical temperature reaches 900 °C. When the bulk items 1 are removed from the cooling tower 2, the items are (quite) cold. Typical temperatures are now between 70 ° C and 150 ° C. The cooling of the hot bulk items 1 is generally performed by the air flow 4 flowing through the cooling tower 2. Therefore, the gas stream 4 is introduced into the cooling tower 2 in a cold state (temperature is usually equal to the ambient temperature), and is taken from the cooling tower 2 in a hot state (temperature is usually between 600 ° C and 800 ° C). from.
冷卻塔2通常被配置在一建築物10中。此建築物10具有多個側壁11。此諸側壁11從底部起延伸至冷卻塔2之一中間高度h處。通常，相對於此冷卻塔2之整個高度H，此中間高度h係介於此冷卻塔2之整個高度H的40%與60%之間。Cooling tower 2 is typically disposed in a building 10. This building 10 has a plurality of side walls 11. The side walls 11 extend from the bottom to an intermediate height h of one of the cooling towers 2. Typically, this intermediate height h is between 40% and 60% of the entire height H of the cooling tower 2 relative to the entire height H of the cooling tower 2.
送氣裝置8(特別是如果其被實施成一風扇)可被配置在建築物10內部。然而，送氣裝置8通常被配置在建築物10外部。帶離裝置9被配置在冷卻塔2之上部區域中，且因此在建築物10之外部。The air supply device 8 (especially if it is implemented as a fan) can be disposed inside the building 10. However, the air supply device 8 is typically disposed outside of the building 10. The strapping device 9 is arranged in the upper region of the cooling tower 2 and is therefore outside the building 10.
帶離裝置9可被配置在冷卻塔2之上表面12上。帶離裝置9較佳的是被配置在塔外壁6中，亦即在側面。The strapping device 9 can be disposed on the upper surface 12 of the cooling tower 2. The strapping device 9 is preferably arranged in the outer wall 6 of the tower, i.e. on the side.
複數個氣流引導手段13被配置在冷卻塔2中。原則上，氣流引導手段13之最小數量係兩個。然而，實際上本實施例中至少有六個氣流引導手段13。原則上，氣流引導手段13之最大數量係無限制的。然而，通常數量不會超過40個。在大部分之情形中，氣流引導手段13之數量係介於8與16之間。A plurality of airflow guiding means 13 are disposed in the cooling tower 2. In principle, the minimum number of airflow guiding means 13 is two. However, actually there are at least six airflow guiding means 13 in this embodiment. In principle, the maximum number of airflow guiding means 13 is unlimited. However, the number usually does not exceed 40. In most cases, the number of airflow guiding means 13 is between 8 and 16.
諸氣流引導手段13被實施成如第1圖中所示之細長形引導手段。此諸手段具有被配置在塔外壁6之入口14。從此諸入口14處，氣流引導手段13徑向地朝內延伸至冷卻塔2之主軸3。此諸氣流引導手段13之發展例如可為輪輻狀(如圖所示)、新月形等。其他之發展亦係可能的。唯一之重要因素在於：其與冷卻塔2之主軸3相隔的距離必須沿著氣流引導手段之縱向延長而減小。The airflow guiding means 13 are embodied as an elongated guiding means as shown in Fig. 1. These means have an inlet 14 that is disposed at the outer wall 6 of the tower. From here the inlets 14, the air flow guiding means 13 extend radially inwards to the main shaft 3 of the cooling tower 2. The development of the airflow guiding means 13 may be, for example, a spoke shape (as shown), a crescent shape or the like. Other developments are also possible. The only important factor is that its distance from the main shaft 3 of the cooling tower 2 must be reduced along the longitudinal extension of the air flow guiding means.
諸氣流引導手段13(當由其各自之延伸方向觀看時在其長度上)具有可供氣流4用之出口15。氣流4(在仍冷之時刻)藉由諸入口14被引入諸氣流引導手段13內，並藉由諸出口15而自該處被引導至位於冷卻塔2中之諸熱散裝物品內。The air flow guiding means 13 (on their length when viewed from their respective extension directions) have an outlet 15 for the air flow 4. The gas stream 4 (when still cold) is introduced into the gas flow guiding means 13 by means of the inlets 14 and is guided therefrom by the outlets 15 into the heat-dissipating articles located in the cooling tower 2.
諸氣流引導手段13之截面在從其長度上觀看時可為恆定的。然而，諸氣流引導手段13之截面較佳地係朝冷卻塔2之主軸3而減小，對應第1圖所示。The cross-section of the airflow guiding means 13 can be constant when viewed from its length. However, the cross-section of the airflow guiding means 13 is preferably reduced toward the main shaft 3 of the cooling tower 2, as shown in Fig. 1.
當由冷卻塔2之主軸3方向觀看時，諸氣流引導手段13被配置在冷卻塔2之中央區域16。此中央區域16從冷卻塔2之整個高度H的大約30%處起延伸至冷卻塔2之整個高度H的大約70%處。然而，與諸氣流引導手段13之精確配置無關的是，此諸氣流引導手段13被配置在帶離裝置9之下方。當冷卻塔2被配置在建築物10中時，諸入口14被附加地配置在建築物10之頂部17下方。因此，建築物10之諸側壁11延伸直至超過諸氣流引導手段13之諸入口14處。由於諸氣流引導手段13位於帶離裝置9下方之配置，使得氣流4由底部至頂部地橫貫位於冷卻塔2中之諸熱散裝物品1(反向流原理)。The airflow guiding means 13 are disposed in the central region 16 of the cooling tower 2 when viewed from the direction of the main shaft 3 of the cooling tower 2. This central region 16 extends from approximately 30% of the entire height H of the cooling tower 2 to approximately 70% of the entire height H of the cooling tower 2. However, irrespective of the precise configuration of the airflow guiding means 13, the airflow guiding means 13 are disposed below the strapping means 9. When the cooling tower 2 is disposed in the building 10, the inlets 14 are additionally disposed below the top 17 of the building 10. Thus, the side walls 11 of the building 10 extend beyond the inlets 14 of the airflow guiding means 13. Since the airflow guiding means 13 are located below the belt-off device 9, the airflow 4 traverses the heat-dissipating articles 1 (reverse flow principle) located in the cooling tower 2 from the bottom to the top.
原則上，諸氣流引導手段13能以水平方式延伸。然而，相對應於第1圖中所示者，諸氣流引導手段13較佳的是與水平面形成一傾斜角度β，以便使諸氣流引導手段13朝冷卻塔2之主軸3向上傾斜。此傾斜角度β可依需要被決定。此傾斜角度β較佳的是可被選擇成使其大致與散裝物品角度α相對應。具體而言，傾斜角度β應介於20°與45°間。介於28°與40°間之值尤其較佳。In principle, the airflow guiding means 13 can extend in a horizontal manner. However, corresponding to those shown in Fig. 1, the airflow guiding means 13 preferably form an oblique angle β with the horizontal plane so that the airflow guiding means 13 are inclined upward toward the main shaft 3 of the cooling tower 2. This tilt angle β can be determined as needed. Preferably, the angle of inclination β can be selected such that it substantially corresponds to the angle α of the bulk item. Specifically, the inclination angle β should be between 20° and 45°. A value between 28 and 40 is especially preferred.
原則上，可在諸氣流引導手段13中之多個任意點處設置出口15。然而，較佳的是，對應於第2圖所示者，此諸出口15被專屬地配置在諸氣流引導手段13之底部表面上。具體而言，如第2圖所示者，此諸氣流引導手段13在其整個底部表面上可為敞開的。在此情形中，諸氣流引導手段13較佳的是具有兩個側面區域18及一頂部區域19。諸側面區域18大致呈垂直地延伸。頂部區域19則橋接諸側面區域18。頂部區域19較佳的是具有一倒“V”形之截面。In principle, the outlet 15 can be provided at any of a number of points in the airflow guiding means 13. However, it is preferable that the outlets 15 are exclusively disposed on the bottom surface of the airflow guiding means 13 corresponding to those shown in Fig. 2. Specifically, as shown in Fig. 2, the airflow guiding means 13 may be open on the entire bottom surface thereof. In this case, the airflow guiding means 13 preferably have two side regions 18 and a top region 19. The side regions 18 extend generally vertically. The top region 19 then bridges the side regions 18. The top region 19 preferably has an inverted "V" shaped cross section.
諸氣流引導手段13可終止於冷卻塔2之主軸3的前方。然而，此諸氣流引導手段13較佳的是延伸直至主軸3處(或直至一配置在冷卻塔2之主軸3區域中的「轂部」20處)。The air flow guiding means 13 may terminate in front of the main shaft 3 of the cooling tower 2. However, the airflow guiding means 13 preferably extend up to the main shaft 3 (or up to a "hub portion" 20 disposed in the region of the main shaft 3 of the cooling tower 2).
當冷卻塔2被配置在建築物10內部時，移除裝置7通常也被配置在建築物10之內部。因此，被從冷卻塔2處所移除之諸散裝物品1(仍然)如最初地被置於建築物10之內部。因此，在此情形中，此冷卻設備具有一裝置，而被從冷卻塔2處所移除之諸散裝物品1則藉此裝置被帶離建築物10。此裝置較佳地被實施成一如第3圖中所示之連續式輸送裝置21。When the cooling tower 2 is disposed inside the building 10, the removal device 7 is also typically disposed inside the building 10. Therefore, the bulk items 1 removed from the cooling tower 2 (still) are initially placed inside the building 10. Therefore, in this case, the cooling device has a device, and the bulk items 1 removed from the cooling tower 2 are thereby carried away from the building 10. This device is preferably implemented as a continuous conveyor 21 as shown in Figure 3.
尤其是在送氣裝置8成一風扇型式之情形中，當氣流4因此在一開始時被吹至建築物10內，並藉由諸入口14而僅從該處被引導至諸氣流引導手段13內時，連續式輸送裝置21可從建築物10露出，並且再度進入建築物10，而在連續式輸送裝置21中之諸通道區域22應相對被密封。為達成此目的，如第3圖中所示，此連續式輸送裝置21可具有多個槽狀容器23。當相對於輸送方向x橫向觀看時，此諸容器23具有一如第4圖所示之容器截面。當朝輸送方向x觀看時，此諸容器具有一如第3圖所示之長度l。例如，連續式輸送裝置21因此可被實施成一種所謂之輸送機，其包括多個具有交叉通道之波狀側壁。In particular, in the case where the air supply unit 8 is in the form of a fan, when the air flow 4 is thus blown into the building 10 at the beginning and is guided from the other to the air flow guiding means 13 by the inlets 14 The continuous conveyor 21 can be exposed from the building 10 and re-enter the building 10, while the passage areas 22 in the continuous conveyor 21 should be relatively sealed. To achieve this, as shown in FIG. 3, the continuous conveyor 21 can have a plurality of trough-like containers 23. The containers 23 have a container cross section as shown in Fig. 4 when viewed transversely with respect to the conveying direction x. The containers have a length l as shown in Fig. 3 when viewed in the conveying direction x. For example, the continuous conveyor 21 can thus be implemented as a so-called conveyor comprising a plurality of undulating sidewalls having intersecting passages.
讓多個連續輸送機裝置21(更精確而言：多個容器23)得以藉由從建築物10處露出並進入建築物10內通道區域22，其較佳的是被實施成隧道。此諸通道區域(隧道)22具有一可順應該容器截面之截面，如第4圖所示。在適當處，多個密封唇或類似者可被配置在諸隧道壁之側面。當朝輸送方向x觀看時，諸隧道22在各種情形下亦具有一隧道長度L，其係大於容器長度l。隧道長度L較佳的是，甚至其長度至少係容器長度l的兩倍，例如大約2.5至3.5倍長。A plurality of continuous conveyor devices 21 (more precisely: a plurality of containers 23) are allowed to be tunneled by being exposed from the building 10 and into the passage area 22 in the building 10. The passage areas (tunnels) 22 have a cross section that conforms to the cross section of the container, as shown in Fig. 4. Where appropriate, a plurality of sealing lips or the like may be disposed on the sides of the tunnel walls. When viewed in the transport direction x, the tunnels 22 also have a tunnel length L in each case which is greater than the length l of the container. The tunnel length L is preferably such that its length is at least twice the length l of the container, for example about 2.5 to 3.5 times longer.
本發明具有許多優點。尤其是，可較高效率地冷卻位於冷卻塔2中之諸熱散裝物品1。此外，由於本發明中所請求之冷卻設備僅具有很少之機械組件。因此，在其生產成本及維護兩方面皆優於習知之系統。除此之外，本發明所需之冷卻空氣量小於先前技藝。因此，送氣裝置8之尺寸相較於習知冷卻設備之尺寸要小。任何隨後被連接至帶離裝置9上的清潔與除塵裝置在尺寸上亦可被設計成較小於先前技藝者。以上為專門用以說明本發明之敘述。對照本發明之保護範圍，將獨有地藉由所附申請專利範圍而決定。The invention has many advantages. In particular, the heat-packed articles 1 located in the cooling tower 2 can be cooled more efficiently. Furthermore, since the cooling device claimed in the present invention has only a few mechanical components. Therefore, it is superior to the conventional system in both its production cost and maintenance. In addition to this, the amount of cooling air required by the present invention is less than in the prior art. Therefore, the size of the air supply unit 8 is smaller than that of the conventional cooling device. Any cleaning and dedusting device that is subsequently attached to the tape removal device 9 can also be sized smaller than prior art. The above is a description specifically for explaining the present invention. The scope of protection of the present invention will be determined solely by the scope of the appended claims.
