Description

分餾盤Fractionation tray

本創作係一種分餾及熱交換盤，尤指能設置於萃取分離及熱交換等裝置之塔槽內部，並能提升物質之分離及熱交換效率的分餾盤，本創作之多數通氣口及多數導氣結構能有效導體之流動，增加氣液的接觸時間，減少導氣結構之死角，並能於塔槽中減少由氣體帶液滴往上層之分餾盤移動的比例。This creation is a fractionation and heat exchange tray, especially a fractionation tray that can be installed in the tower tank of extraction separation and heat exchange devices, and can improve the separation and heat exchange efficiency of substances. The gas structure can effectively conduct the flow of conductors, increase the contact time of gas and liquid, reduce the dead angle of the gas guide structure, and reduce the proportion of liquid droplets moving from the gas to the upper fractionation tray in the tower groove.

蒸餾塔、萃取塔、吸收塔或脫除塔等萃取分離裝置係利用不同成份之物質的沸點差異以分離混和液中的物質，所述萃取分離裝置包含一塔槽、交錯且間隔設置於所述塔槽中的複數分餾盤及設置於所述塔槽底部的一加熱器，混合液會被導入所述塔槽中，並流動到所述塔槽底部，所述加熱器會加熱而使部分混和液汽化並產生氣體，當向下流動的液體與向上移動的氣體接觸時，液體中較易揮發的物質會轉移至氣體中，而氣體中較難揮發的物質會轉移至液體中，藉此使混和液中的物質能依據易揮發程度而於所述塔槽中分離。Extraction and separation devices such as distillation towers, extraction towers, absorption towers or removal towers use the difference in boiling point of substances of different components to separate substances in the mixed liquid. A plurality of fractionation trays in the tower tank and a heater arranged at the bottom of the tower tank, the mixed liquid will be introduced into the tower tank and flow to the bottom of the tower tank, and the heater will heat and partially mix The liquid vaporizes and generates a gas. When the downward flowing liquid contacts the upward moving gas, the more volatile substances in the liquid are transferred to the gas, and the less volatile substances in the gas are transferred to the liquid, thereby making the The substances in the mixed liquid can be separated in the column tank according to the degree of volatility.

其中，所述分餾盤上間隔地形成有多數通口，當液體於所述塔槽中向下流動時會一層一層地流經交錯的分餾盤，而氣體向上移動時會通過所述分餾盤上的通口，並接觸而攪動所述分餾盤上的液體，使氣體與液體中的物質更容易相互轉移，惟當氣體通過所述分餾盤之通口時，由於沒有任何遮擋，氣體會直接向上衝升，造成氣體與液體之間的接觸時間不足，而無法充分進行攪動作用，又產生之液滴會被氣體帶至位於上層的分餾盤，導致分離效率減低。Wherein, a plurality of ports are formed on the fractionating tray at intervals. When the liquid flows downward in the tower tank, it will flow through the staggered fractionating trays layer by layer, and when the gas moves upward, it will pass through the fractionating tray. The through port of the fractionation tray is contacted to agitate the liquid on the fractionation tray, so that the substances in the gas and the liquid can be transferred to each other more easily. As a result, the contact time between the gas and the liquid is insufficient, so that the stirring effect cannot be fully performed, and the generated droplets will be carried by the gas to the upper fractionation tray, resulting in a decrease in the separation efficiency.

為了改善前述情形，如圖10所示，現今之分餾盤包含形成有多數通口81的一板體80及拱型的多數遮擋結構90，該多數遮擋結構90間隔地設置於該板體80，並分別跨過該多數通口81的上方，所述遮擋結構90的左右兩側分別與所述板體80之間形成有一出口91，所述出口91連通該通口81，當氣體向上移動並通過所述板體80之通口81時，會被所述遮擋結構90阻擋而不會直接向上衝升，並轉向朝所述遮擋結構90左右兩側的出口91導出再上升，藉此增加氣體的流動路徑，以增加氣體與液體之間的攪動作用。In order to improve the aforementioned situation, as shown in FIG. 10 , the present fractionating tray includes a plate body 80 formed with a plurality of openings 81 and a plurality of arch-shaped shielding structures 90 . The shielding structures 90 are arranged on the plate body 80 at intervals. and respectively straddling the top of the plurality of through ports 81, an outlet 91 is formed between the left and right sides of the shielding structure 90 and the plate body 80 respectively, and the outlet 91 communicates with the through port 81. When passing through the opening 81 of the plate body 80 , it will be blocked by the shielding structure 90 and will not directly rise upward, and will be turned to the exits 91 on the left and right sides of the shielding structure 90 to be led out and then ascended, thereby increasing the gas flow path to increase agitation between gas and liquid.

然而，當氣體通過所述分餾盤而自所述遮擋結構90左右兩側的出口91導出時，自二相鄰的遮擋結構90的相對側之出口91導出的氣體會相互碰撞，而於二相鄰的遮擋結構90之間的位置直接上升，使得氣體較難以與所述遮擋結構90周遭及上方的液體進行攪動，造成分離效率降低，同時由於所述遮擋結構90之死角較多，而會造成液相中的固體阻塞，而仍有改善之空間。However, when the gas is led out from the outlets 91 on the left and right sides of the shielding structure 90 through the fractionation tray, the gases led out from the outlets 91 on the opposite sides of the two adjacent shielding structures 90 will collide with each other, and the two-phase The position between the adjacent shielding structures 90 rises directly, making it difficult for the gas to agitate with the liquid around and above the shielding structures 90, resulting in lower separation efficiency. Solids in the liquid phase block and there is still room for improvement.

本創作之主要目的在於提供一分餾盤，希藉此改善現今之分餾盤的遮擋結構周遭及上方的液體難以被氣體接觸攪動，使得物質之分離效率降低之問題。The main purpose of this creation is to provide a fractionating tray, thereby improving the problem that the liquid around and above the shielding structure of the current fractionating tray is difficult to be contacted and agitated by gas, which reduces the separation efficiency of substances.

In addition, the first connecting parts 24 of the plurality of gas guiding structures 20 are oriented in the same direction, and the width of the first connecting parts 24 larger than the width of the second connecting portion 26 .

本創作分餾盤能裝設於一萃取分離裝置之塔槽中，並使該多數導氣結構20之第一連接部24至第二連接部26之方向與液體於所述分餾盤上的流向同方向，當所述萃取分離裝置運作時，液體會流經所述分餾盤之盤體10上方，氣體會自所述分餾盤的下方往上升，而接觸到該盤體10的底部，並能通過該盤體10之該多數通氣口11而進入該多數導氣結構20之導氣空間21中。The fractionation tray of the present invention can be installed in the tower tank of an extraction and separation device, and the direction of the first connection part 24 to the second connection part 26 of the plurality of gas guide structures 20 is the same as the flow direction of the liquid on the fractionation tray When the extraction and separation device operates, the liquid will flow above the disc body 10 of the fractionation tray, and the gas will rise from the bottom of the fractionation tray, contact the bottom of the disc body 10, and pass through The plurality of ventilation openings 11 of the disk body 10 enter into the air guiding spaces 21 of the plurality of air guiding structures 20 .

此時，如圖7及圖8所示，以氣體通過一個所述通氣口11而言，氣體能進入所述通氣口11上方的導氣結構20之導氣空間21，並能通過所述導氣結構20之導氣孔23及所述導氣結構20之左右兩側的出氣口22，而導出至所述分餾盤的上方，並能與該盤體10上流過的液體接觸及攪動，使氣體及液體中不同成分的物質能因沸點高低的差異而進行轉移，藉此使物質分離而達到分餾的效果。At this time, as shown in FIG. 7 and FIG. 8 , as far as the gas passes through one of the air vents 11 , the gas can enter the air guiding space 21 of the air guiding structure 20 above the air vent 11 , and can pass through the air guiding space 21 . The air guide holes 23 of the air guide structure 20 and the air outlets 22 on the left and right sides of the air guide structure 20 are led out to the top of the fractionation plate, and can be contacted and stirred with the liquid flowing on the plate body 10 to make the gas And the substances of different components in the liquid can be transferred due to the difference in boiling point, so as to separate the substances and achieve the effect of fractionation.

其中，藉由所述導氣孔23之設計能將氣體導引至所述導氣結構20的上方，並能增加氣體之流動路徑，使氣體更容易接觸液體，且液體於該盤體10上流動時，能先接觸寬度較寬之該第一連接部24，進而增加液體之擾動，藉此能增加氣體與液體之間的攪拌作用，而提升物質分離及熱交換之效率。The design of the air guide holes 23 can guide the gas to the top of the air guide structure 20 , and can increase the flow path of the gas, so that the gas can more easily contact the liquid, and the liquid flows on the disk body 10 . When the first connecting portion 24 with a wider width can be contacted first, the disturbance of the liquid can be increased, thereby increasing the stirring effect between the gas and the liquid, and improving the efficiency of material separation and heat exchange.

再者，當氣體通過所述導氣結構20之第一連接部24、導引部25或第二連接部26上的導氣孔23時能被向上導出，而當氣體接觸到所述導氣結構20之導引部25之底部的該二導引斜面251時，會受所述導引斜面251引導而通過該二出氣口22，並能朝所述導氣結構20之左右兩側的斜上方導出，因此，所述導氣孔23及所述導引斜面251之設計皆能使氣體向上導出，而增加氣體與所述導氣結構20之上方的液體之間的接觸，進而能提升氣體與液體之間的攪動作用，藉此有效提升分離及熱交換效率。Furthermore, when the gas passes through the first connecting part 24, the guiding part 25 or the air guiding hole 23 on the second connecting part 26 of the air guiding structure 20, it can be guided upward, and when the gas contacts the air guiding structure When the two guiding inclined surfaces 251 at the bottom of the guiding portion 25 of the 20 are guided by the guiding inclined surfaces 251 and pass through the two air outlets 22, they can be directed to the obliquely upwards of the left and right sides of the air guiding structure 20. Therefore, the design of the air guide holes 23 and the guide slopes 251 can both enable the gas to be led out upward, thereby increasing the contact between the gas and the liquid above the air guide structure 20, thereby improving the gas and the liquid. The stirring effect between them can effectively improve the separation and heat exchange efficiency.

此外，透過所述導引斜面251呈傾斜之設計，使氣體除了以橫向方向而自所述導氣結構20的左右兩側導出外，亦會沿斜向方向而朝所述導氣結構20的斜上方導出，並透過所述導氣孔23之分流，而使通過所述出氣口22的氣體減少，因此能避免氣體或液體中較難揮發的物質或雜質於通過所述出氣口22時殘留在該導引部25與所述出氣口22的邊緣，以避免汙染通過所述導氣結構20的氣體或液體。In addition, through the inclined design of the guiding inclined surface 251 , the gas is not only led out from the left and right sides of the gas guiding structure 20 in the lateral direction, but also directed toward the gas guiding structure 20 in the oblique direction. The gas is led out obliquely upward and passes through the shunt of the air guide hole 23 , so that the gas passing through the air outlet 22 is reduced, so that the less volatile substances or impurities in the gas or liquid can be prevented from remaining in the air outlet 22 when passing through the air outlet 22 . The guide portion 25 and the edge of the air outlet 22 are used to avoid contamination of the gas or liquid passing through the air guide structure 20 .

另外，如圖9所示，以氣體通過複數個相鄰的所述通氣口11而言，藉由每一所述通氣口11上方的導氣結構20之引導，使氣體能自所述導氣孔23或所述出氣口22導出，而能分布於所述導氣結構20上方或二相鄰的導氣結構20之間，且氣體自每二相鄰的導氣結構20之相對側的出氣口22導出時係朝斜上方移動，因此能減少氣體相互碰撞，並增加氣體於所述導氣結構20周遭的分佈範圍，能提升氣體通過所述分餾盤時的均勻度，並藉此增加氣體與液體之間的攪動作用。In addition, as shown in FIG. 9 , in the case of gas passing through a plurality of adjacent air holes 11 , the gas can be guided from the air guide holes by the guide structure 20 above each of the air holes 11 . 23 or the air outlet 22, and can be distributed above the air guide structure 20 or between two adjacent air guide structures 20, and the gas is from the air outlet on the opposite side of each two adjacent air guide structures 20 22 moves obliquely upward when it is exported, so it can reduce the collision of the gases with each other, and increase the distribution range of the gas around the gas guide structure 20, which can improve the uniformity of the gas passing through the fractionation tray, and thereby increase the gas and the gas. agitation between liquids.
