Description
本發明係與高分子廢棄物熱裂解油化系統有關，特別是指一種高分子廢棄物熱裂解油化系統之裂解槽裝置。The invention relates to a polymer waste thermal cracking oilization system, in particular to a cracking tank device of a polymer waste thermal cracking oilification system.
熱裂解法是指將一般高分子廢棄物置於無氧或少量氧氣之狀態下，利用熱能裂解使其分解，成為氣體、液體或殘渣之處理方法，換言之，即將高分子廢棄物轉換成可回收之資源油、裂解氣及焦碳等產物。The thermal cracking method refers to a method in which a general polymer waste is placed in a state of no oxygen or a small amount of oxygen, and is decomposed by thermal energy cracking to be a gas, a liquid or a residue, in other words, a polymer waste is converted into a recyclable product. Resources such as resource oil, cracked gas and coke.
參閱第1圖，顯示習用高分子廢棄物熱裂解油化系統示意圖，其主要將高分子廢棄物連同催化劑或其他必要的化學物質置入攪拌槽11內進行攪拌混合，攪拌混合而成的被裂解廢棄物係呈液固流體狀，其並藉由管件12進入裂解槽裝置，亦即由第一裂解槽13上端的入料口131流至於其內，藉以進行熱裂解作業，熱裂解而成的油氣則由第一裂解槽13上端的油氣出口132排出，並經分餾系統14冷卻獲取資源油，而尚未列解完全的被裂解廢棄物則被螺旋輸送單元15推動，使其流經第一裂解槽13下端的出料口133、管子134、最終由第二裂解槽16上端的入料口161流至於其內，讓尚未裂解完全的被裂解廢棄物於該第二裂解槽16內再次進行熱裂解作業，以達最佳的產能。然而，習用高分子廢棄物熱裂解油化系統的裂解槽裝置雖然可以縮減整體裂解反應的時間、增加攪拌槽11每一批次裂解之處理量、增進反應效果、加快反應速率、以及避免焦碳於裂解槽中過度加溫或過反應時間過長而造成型態改變，但是其於實際使用情形，該裂解槽裝置仍具有須立即改善之缺陷。Referring to Fig. 1, there is shown a schematic diagram of a conventional polymer waste thermal cracking oilification system, which mainly incorporates polymer waste together with a catalyst or other necessary chemical substance into a stirred tank 11 for stirring and mixing, and is stirred and mixed to be cracked. The waste is in the form of a liquid-solid fluid, which is introduced into the cracking tank device by the pipe member 12, that is, from the inlet port 131 at the upper end of the first cracking tank 13, to be thermally cracked and thermally cracked. The oil and gas is discharged from the oil and gas outlet 132 at the upper end of the first cracking tank 13, and is cooled by the fractionation system 14 to obtain the resource oil, and the completely cracked waste which has not yet been exhausted is pushed by the screw conveying unit 15 to flow through the first cracking. The discharge port 133 at the lower end of the tank 13 and the pipe 134 are finally flowed into the inlet port 161 of the upper end of the second cracking tank 16, so that the cracked waste which has not been completely cracked is again heatd in the second cracking tank 16. Cracking operations to achieve optimum capacity. However, the cracking tank device of the conventional polymer waste thermal cracking oilification system can reduce the time of the overall cracking reaction, increase the throughput of each batch of cracking of the stirring tank 11, improve the reaction effect, accelerate the reaction rate, and avoid coke. Excessive heating or over-reaction in the cracking tank causes the type to change, but in actual use, the cracking tank device still has defects that need to be improved immediately.
其一、由於其第一、二裂解槽13、16係呈水平橫臥的型態設置於平面上，因此，令被裂解廢棄物進入於最後一裂解槽(即第二裂解槽16)內後，可能尚未完全被裂解而成為殘渣，第二裂解槽16內的螺旋輸送單元15會將尚未完全被列解的殘渣由其下端的出料口162送出至乾燥系統17，此時，由於第二裂解槽16並無預先乾燥段的設計，因此，被完全裂解而成為殘渣的乾燥時間過短，使殘渣的焦油量過高，無法獲得更質純的焦碳，因而無法精煉作為碳黑或活性碳的原料。First, since the first and second cracking tanks 13, 16 are horizontally lying on the plane, the cracked waste is allowed to enter the last cracking tank (ie, the second cracking tank 16). , may not have been completely cracked to become a residue, the screw conveying unit 15 in the second cracking tank 16 will send the residue that has not been completely decomposed to the drying system 17 from the discharge port 162 at the lower end thereof, at this time, due to the second The cracking tank 16 has no pre-drying section design. Therefore, the drying time of being completely cracked to become a residue is too short, so that the amount of tar of the residue is too high, and a more pure coke cannot be obtained, so that it cannot be refined as carbon black or active. Carbon raw materials.
其二、同樣由於第一、二裂解槽13、16係呈水平橫臥的型態設置於平面上，因此，各裂解槽進行裂解作業所產生的油氣並無法順利的由第一、二裂解槽13、16上端的油氣出口132、163排出，而會積聚在各裂解槽內槽壁與該螺旋輸送單元15螺旋葉片151的上方，造成輸送不平順、產能及效率的不足。Secondly, since the first and second cracking tanks 13 and 16 are horizontally lying on the plane, the oil and gas generated by the cracking operation of each cracking tank cannot be smoothly solved by the first and second cracking tanks. The oil and gas outlets 132 and 163 at the upper end of the 13 and 16 are discharged, and accumulate in the groove wall in each cracking tank and above the spiral blade 151 of the screw conveying unit 15, resulting in insufficient conveying, productivity, and efficiency.
據此，如何開發出一種高分子廢棄物熱裂解油化系統之裂解槽裝置，其可解決上述問題，即是本發明急欲解決的問題，亦是本發明研發的動機。Accordingly, how to develop a cracking tank device for a polymer waste thermal cracking oilification system, which solves the above problems, is an urgent problem to be solved by the present invention, and is also an incentive for the development of the present invention.

至於本發明實施例的作動方式及其功效，做以下說明。As for the operation mode and the effect of the embodiment of the present invention, the following description will be made.
當預熱熔化的高分子廢棄物進入攪拌槽52將所攪拌混合後的添加物和被裂解廢棄物通過管件51經過該第一裂解槽20的入料口231而位於其內進行熱裂解作業，經控制其前段23的熱夾套21加熱，使該前段23升溫至340至380℃之間時，部份的被裂解廢棄物已被熱裂解，而未熱裂解的被裂解廢棄物則被轉動的螺旋輸送單元40送至第一裂解槽20的後段24，並控制所對應的熱夾套22加熱，使該後段24升溫至380至420℃之間繼續熱裂解，已熱裂解產生的油氣經由該螺旋輸送單元40的螺旋葉片43葉緣處的缺口431，再經過下一葉緣處的缺口431，依此類推，該油氣即可經由該第一裂解槽20底部送至上端的油氣出口241，而得以被分餾系統53負壓很平順的抽出，以進行分餾、冷卻獲取資源油氣的程序作業。When the preheated molten polymer waste enters the agitation tank 52, the agitated mixed additive and the cracked waste are passed through the pipe member 51 through the inlet port 231 of the first cracking tank 20 to be thermally cracked therein. After heating the hot jacket 21 of the front section 23 to heat the front section 23 to between 340 and 380 ° C, part of the cracked waste has been thermally cracked, and the unheated cracked waste is rotated. The spiral conveying unit 40 is sent to the rear section 24 of the first cracking tank 20, and controls the corresponding hot jacket 22 to be heated, so that the rear section 24 is heated to between 380 and 420 ° C to continue thermal cracking, and the oil and gas generated by the thermal cracking is passed through The notch 431 at the leaf edge of the spiral blade 43 of the screw conveying unit 40 passes through the notch 431 at the next blade edge, and so on, and the oil and gas can be sent to the upper end oil and gas outlet 241 through the bottom of the first cracking tank 20. It can be extracted smoothly by the fractionation system 53 under negative pressure to perform fractionation and cooling to obtain the resource oil and gas.
而尚未裂解完全的被裂解廢棄物則被螺旋輸送單元40推動，使其流經第一裂解槽20的出料口242，並由最末裂解槽30的入料口331流至於其內，尚未熱裂解完全的被裂解廢棄物在該最末裂解槽30的前段33再次進行熱裂解作業，經控制其前段33的熱夾套31加熱，使前段33升溫至420至450℃間時，令該被裂解廢棄物完全被裂解成殘渣，被熱裂解完成的殘渣則被該螺旋輸送單元40送至最末裂解槽30的後段34進行預乾燥作業，其可控制後段34的熱夾套32加熱，使後段34升溫至450℃以上進行殘渣預乾燥，最後由該最末裂解槽30出料口342輸出至乾燥系統57進行乾燥作業。同樣的，該最末裂解槽30熱裂解所生成的油氣得以由其上端的油氣出口341，而被分餾系統53負壓很平順的抽出，以進行分餾、冷卻獲取資源油氣的程序作業。The cracked waste which has not been completely cracked is pushed by the screw conveying unit 40 to flow through the discharge port 242 of the first cracking tank 20, and flows into the inlet port 331 of the last cracking tank 30, and has not yet been therein. The thermally cracked completely cracked waste is again subjected to a thermal cracking operation in the front section 33 of the last cracking tank 30, and is heated by the hot jacket 31 controlling the front section 33 to raise the front section 33 to 420 to 450 ° C. The cracked waste is completely cracked into a residue, and the residue which is thermally cracked is sent to the rear section 34 of the last cracking tank 30 by the screw conveying unit 40 for pre-drying operation, which can control the heat jacket 32 of the rear section 34 to be heated. The temperature of the rear stage 34 is raised to 450 ° C or higher to carry out pre-drying of the residue, and finally, the discharge port 342 of the last cracking tank 30 is output to the drying system 57 for drying. Similarly, the oil and gas generated by the thermal cracking of the last cracking tank 30 can be taken out by the oil and gas outlet 341 at the upper end thereof, and is smoothly extracted by the fractionating system 53 for the purpose of fractionation and cooling to obtain the resource oil and gas.
本發明藉上述具體實施例之結構，可得到下述的功效：According to the structure of the above specific embodiment, the present invention can obtain the following effects:
其一、由於該第一裂解槽20與最末裂解槽30係由後段24、34高於前段23、33的方式依序設置，使該第一裂解槽20與最末裂解槽30呈傾斜狀的型態設置，特別是最末裂解槽30的入料口331低於出料口342，使其後段34為預乾燥段，因此，令被裂解廢棄物進入於最末裂解槽30內後，於其前段33可完全被裂解而成為殘渣，最末裂解槽30內的螺旋輸送單元40會將殘渣由其前段33送至後段34(即預乾燥段)，此時，被完全裂解而成為殘渣在該後段34可被預先進行乾燥作業，降低殘渣的焦油含量，使得殘渣由該最末裂解槽30下端的出料口342送出至乾燥系統57進行乾燥作業後，使乾燥系統作業更順利。First, since the first cracking tank 20 and the last cracking tank 30 are sequentially disposed in a manner that the rear sections 24 and 34 are higher than the front sections 23 and 33, the first cracking tank 20 and the last cracking tank 30 are inclined. The type setting, in particular, the inlet port 331 of the last cracking tank 30 is lower than the discharge port 342, so that the rear section 34 is a pre-drying section. Therefore, after the cracked waste enters the last cracking tank 30, In the front section 33, it can be completely cracked to become a residue, and the screw conveying unit 40 in the last cracking tank 30 sends the residue from the front section 33 to the rear section 34 (i.e., the pre-drying section), at which time it is completely cracked to become a residue. In the rear section 34, the drying operation can be performed in advance to reduce the tar content of the residue, so that the residue is sent out from the discharge port 342 at the lower end of the last cracking tank 30 to the drying system 57 for drying operation, thereby making the drying system work more smoothly.
其二、同樣由於該第一裂解槽20與最末裂解槽30呈傾斜狀的型態設置，因此，被裂解廢棄物因各裂解槽呈傾斜狀所以有較大停留空間，而得以增加被裂解廢棄物反應的時間。另外，各裂解槽進行裂解作業所產生的油氣會經過所對應的螺旋輸送單元40螺旋葉片43上的缺口431，藉由分餾系統53負壓很平順的由油氣出口241、341被抽出，以進行分餾、冷卻獲取資源油氣的程序作業，並不會使油氣積聚在各裂解槽槽內壁的上方，造成油氣被抽出不平順，影響產能及效率的不足之缺陷。Secondly, since the first cracking tank 20 and the last cracking tank 30 are arranged in an inclined shape, the cracked waste has a large residence space due to the inclined cracking of each cracking tank, and is increased in cracking. The time of waste reaction. In addition, the oil and gas generated by the cracking operation of each cracking tank passes through the notch 431 on the spiral blade 43 of the corresponding screw conveying unit 40, and is extracted by the oil and gas outlets 241 and 341 by the fractionating system 53 with a negative pressure. The procedure of fractional distillation and cooling to obtain resources and oil and gas does not cause oil and gas to accumulate above the inner walls of each cracking tank, resulting in oil and gas being pumped out unevenly, which affects the defects of production capacity and efficiency.
其三、由於各裂解槽外壁加熱，被裂解廢棄物於熱裂解後通常會產生結焦成為殘渣的物質，且會附著積聚於各該裂解槽內壁面由螺旋葉片43刮除，但該螺旋葉片43的缺口431處會造成殘渣結焦於各該裂解槽的內壁面，因此，可藉由螺旋輸送單元40的螺旋葉片43上所設置的刮除片432，刮除對應螺旋葉片43缺口431處所蓄積的殘渣，使該第一裂解槽20內壁面25以及最末裂解槽30內壁面35可保持有最佳的傳熱面積，同時，亦可得到較均勻的攪拌，達到傳熱率較佳的功效增進，而得以提升產能。Thirdly, due to the heating of the outer wall of each cracking tank, the cracked waste usually generates a material which is coked as a residue after thermal cracking, and adheres to the inner wall surface of each cracking tank and is scraped off by the spiral blade 43, but the spiral blade 43 is scraped. The gap 431 causes the residue to be coked on the inner wall surface of each of the cracking grooves. Therefore, the scraping piece 432 provided on the spiral blade 43 of the screw conveying unit 40 can scrape off the accumulated portion of the corresponding spiral blade 43 at the notch 431. The residue allows the inner wall surface 25 of the first cracking tank 20 and the inner wall surface 35 of the last cracking tank 30 to maintain an optimum heat transfer area, and at the same time, a relatively uniform agitation can be obtained, and the heat transfer rate is improved. And can increase production capacity.
值得一提的是，本發明可以依產量增加而增設裂解槽，當產量增加時可在該第一裂解槽內尚未熱裂解完全的被裂解廢棄物進入最末裂解槽之前，增設與該第一裂解槽相同構造的裂解槽，可依被裂解廢棄物的被裂解溫度類別，增設與該第一裂解槽相同構造的裂解槽並調整設定各裂解槽各段夾套的溫度以得最佳產品。亦即，除了最末裂解槽的入料口低於出料口之外，其餘裂解槽的入料口與出料口係位於同一水平面，除了第一裂解槽的入料口與攪拌槽連通、以及最末裂解槽的出料口與乾燥系統連通之外，各該裂解槽的出料口與相鄰裂解槽的入料口相通。It is worth mentioning that the present invention can add a cracking tank according to the increase of the output, and when the output is increased, the first cracking tank can be added to the first cracking tank before the hot cracking of the completely cracked waste into the last cracking tank. The cracking tank of the same structure of the cracking tank can be added with the cracking tank of the same structure as the cracking temperature of the cracked waste, and the temperature of the jacket of each cracking tank can be adjusted to obtain the best product. That is, except that the inlet port of the last cracking tank is lower than the discharge port, the inlet port and the discharge port of the other cracking tank are at the same level, except that the inlet of the first cracking tank is connected with the stirring tank, And the discharge port of the last cracking tank is connected to the drying system, and the discharge port of each of the cracking tanks communicates with the inlet of the adjacent cracking tank.
