Description
本發明係與造紙廢棄物有關,特別有關於一種從造紙廢棄物中分離塑料與紙料的造紙廢棄物回收系統。The present invention relates to papermaking waste, and more particularly to a papermaking waste recycling system for separating plastics and paper stock from papermaking waste.
目前造紙工業的原料來源有極大比例來自回收廢紙,在這些廢紙中有一部分是結合紙張與塑料的複合材料或是結合紙張、聚乙烯(PE)膜與鋁箔的鋁箔包,由於此種複合材料或鋁箔包的組成材料結合的十分緊密,普通的分離工藝無法完全分離,所以只能作為紙漿廢渣。對於紙漿廢渣的處理,傳統的方式是焚化或掩埋,此方式不僅污染環境,同時亦是資源的浪費。At present, a large proportion of raw materials for the paper industry come from recycled waste paper. Some of these waste papers are composite materials combining paper and plastic or aluminum foil coated with paper, polyethylene (PE) film and aluminum foil. The material of the material or the foil package is very tightly combined, and the ordinary separation process cannot be completely separated, so it can only be used as pulp waste. For the treatment of pulp waste, the traditional way is incineration or landfill, which not only pollutes the environment, but also is a waste of resources.
目前已經有一種分離設備,採用如第一圖所示的工藝流程,對這部分被造紙廠廢棄的塑紙混合廢棄物進行粉碎、沉澱、過濾、浮選等方法把其中雜質(包括石頭、金屬、木材、棉紗、泥沙)分離出來,同時將紙漿和塑料分離出來,紙漿可重新送回造紙廠,塑料可以重新造粒變成塑料原料。At present, there is a separation equipment, which uses the process flow shown in the first figure to pulverize, precipitate, filter, float, etc. the waste paper mixed waste discarded by the paper mill to remove impurities (including stones and metals). The wood, cotton yarn, and sediment are separated, and the pulp and plastic are separated. The pulp can be sent back to the paper mill, and the plastic can be re-granulated into plastic raw materials.
具體的做法是:先用定量皮帶秤1將從紙漿廠運來的潮濕紙漿廢渣(其中包括少量的紙、塑料、磁性金屬與非磁性金屬、石塊、砂子、木材及其他廢棄物)以一定速度送入滾筒篩2,該滾筒篩2的入口端略高於出口端,伴隨著進料在緩慢的旋轉。其中,一部分碎粒雜物會落在收集皮帶運輸機3上,然後被運送至滾筒篩廢棄物倉4,而剩下的較大塊廢渣會從滾筒篩2的出口端落入接續皮帶運輸機5送入粉碎機6,在粉碎機6中係設有噴淋水,大塊的雜物被粉碎成小塊後,進入到開放式分離機7,在其中一面用水噴淋,一面用螺旋送料桿攪拌和送料。The specific method is: first use the quantitative belt scale 1 to transfer the wet pulp residue (including a small amount of paper, plastic, magnetic metal and non-magnetic metal, stone, sand, wood and other wastes) from the pulp mill. The speed is fed into the trommel 2, the inlet end of which is slightly above the outlet end, with the feed being slowly rotated. Among them, a part of the debris will fall on the collecting belt conveyor 3, and then transported to the drum screening waste bin 4, and the remaining larger scrap will fall from the outlet end of the drum screen 2 into the connecting belt conveyor 5 Into the pulverizer 6, the pulverizer 6 is provided with spray water, and the large pieces of debris are pulverized into small pieces, and then enter the open type separator 7, and one side is sprayed with water while stirring with a screw feed rod. And feeding.
接著,從開放式分離機7輸出後,該被粉碎和攪拌的混合雜物進入散漿機8進行強力的攪拌和沉澱,俾較重的砂石、金屬沉澱到底部,並透過散漿機8的雙閘閥排出到散漿機廢棄物倉9,而含有大量塑料的較輕混合雜物則從散漿機8的上方輸出,並進入第二次粉碎處理;該粉碎機10將混合雜物再度粉碎後又一次進入開放式分離機11,並一面噴淋、一面攪拌及一面傳送把混合雜物送入浮選槽12;該浮選槽12設有多個子槽,每個子槽的水位依次降低,俾含有PP、PE、OPP塑料的雜物較輕,可漂在水面上,而該含有PVC、PET塑料的較重,則逐漸下沉到槽底。其中,該漂浮物在多級高度不同的子槽跌落時,每跌落一次就摔打一次,如此,便可實現紙纖維和塑料混合物的分離。Then, after being output from the open separator 7, the pulverized and stirred mixed impurities enter the pulper 8 for vigorous stirring and precipitation, and the heavier sand and metal are precipitated to the bottom and passed through the pulper 8 The double gate valve is discharged to the pulper waste bin 9, and the lighter mixed debris containing a large amount of plastic is output from above the slurry machine 8 and enters the second pulverization process; the pulverizer 10 remixes the mixed debris After the pulverization, the open separator 11 is again introduced, and the mixed impurities are sent to the flotation tank 12 while being sprayed, stirred, and conveyed; the flotation tank 12 is provided with a plurality of sub-tanks, and the water level of each sub-tank is sequentially lowered. The impurities containing PP, PE and OPP plastics are lighter and can float on the water surface, while the heavy ones containing PVC and PET plastics gradually sink to the bottom of the tank. Wherein, the floating object is beaten once every fall when the sub-grooves with different heights of different levels fall, so that the separation of the paper fiber and the plastic mixture can be achieved.
另,該沉澱在浮選槽各子槽底部的混合物係被真空泵驅動的吸管13吸出,而吸管13的移動是由人工來完成的。接著,在最後一個子槽漂出的PP、PE、OPP塑料,經開放式分離機14被送入料倉15,再經與塑料造粒機16製成塑料原料回收。而沉到槽底的PVC、PET混合物則被壓成塑料棒(條),可以做為鍋爐燃料。Further, the mixture of the precipitate at the bottom of each sub-tank of the flotation cell is sucked by the suction pump 13 driven by the vacuum pump, and the movement of the suction pipe 13 is performed manually. Then, the PP, PE, and OPP plastic which are floated in the last sub-tank are sent to the silo 15 through the open separator 14, and then recycled to the plastic raw material by the plastic granulator 16. The PVC and PET mixture that sinks to the bottom of the tank is pressed into a plastic rod (strip) that can be used as boiler fuel.
上述的分離設備仍存在以下問題:初選過程過於簡單,初選效率低,使原料中的雜質分離不充分,給後續的浮選處理帶來很大困難。The above separation equipment still has the following problems: the primary selection process is too simple, the primary selection efficiency is low, and the impurities in the raw materials are not sufficiently separated, which brings great difficulty to the subsequent flotation treatment.
有鑑於此,本發明人為改善並解決上述之缺失,特潛心研究並配合學理之運用,提出一種設計合理且有效改善上述缺失之本發明。In view of the above, the present inventors have made an effort to improve and solve the above-mentioned deficiencies, and to study and cooperate with the application of the theory, and propose a present invention which is reasonable in design and effective in improving the above-mentioned defects.
