Description
本創作係關於用以從油水混合物分離油的油水分離裝置,以及含有該裝置之用以從油水混合物分離油的油水分離系統。詳言之,係關於使用可從油水混合物吸收油而分離油的油水分離劑之油水分離裝置,以及油水分離系統。The present invention relates to a water-oil separation device for separating oil from an oil-water mixture, and a water-oil separation system containing the device for separating oil from an oil-water mixture. More specifically, it relates to an oil-water separation device using an oil-water separating agent that can separate oil from oil-water mixture, and a water-oil separation system.
油與水通常不會混合,但受到超音波或剪切力時,水或油之一方會變成微細的液滴而分散於另一方之水相或油相中,變成乳化狀(乳液)。此般乳液中之油係難以與水分離。因此,含有油與水之乳液的油水混合物係難以油水分離處理,潛在性地存在廢液之處理與油之再利用等多種問題。Oil and water usually do not mix, but when subjected to ultrasonic or shearing force, one of water or oil becomes fine droplets and is dispersed in the other aqueous phase or oil phase to become emulsified (emulsion). The oil in such emulsions is difficult to separate from water. Therefore, the oil-water mixture containing the emulsion of oil and water is difficult to separate from oil and water, and there are many problems such as disposal of waste liquid and reuse of oil.
如此從含有油與水之乳液的油水混合物分離油與水之方法,習知有利用氣化溫度差、比重差、利用微生物、化學處理、利用電性、界面之性質之差異的吸附劑等(例如,專利文獻1至6)。然而,藉由此般方法分離油之方法,有需要大規模設備、處理能力 差、處理費時等問題。因此,對於環境之負荷亦變大,而且,於成本面上,對於企業等的負擔亦增加。例如,於海洋或河川之汚染水中進行油水分離處理時,由於並無短時間內大量處理汚染水中所含之含有油與水之乳液的油水混合物之技術,故油以外之水等亦仍需直接以油水混合物之形式帶回。Thus, a method of separating oil and water from an oil-water mixture containing an emulsion of oil and water is known to have an adsorbent which utilizes a difference in vaporization temperature, a specific gravity, a microorganism, a chemical treatment, an electrical property, and an interface property ( For example, Patent Documents 1 to 6). However, the method of separating oil by this method requires large-scale equipment and processing capability. Poor, processing time and other issues. Therefore, the load on the environment is also increased, and on the cost side, the burden on companies and the like is also increasing. For example, when oil-water separation treatment is carried out in polluted water in the ocean or river, since there is no technology for processing oil-water mixture containing oil and water emulsion contained in polluted water in a short time, water other than oil still needs to be directly Brought back in the form of a mixture of oil and water.

本說明書中,「油水混合物」係指油與水共存之混合物,油水混合物亦包含著含有油以外的其他成分者。油水混合物中所含之油與水係可為分離共存之狀態,亦可為油與水形成之乳液(油水乳液)。而且,油水混合物中可含有一部分之油與水分離之狀態,亦可含有一部分油與水之乳液。In the present specification, "oil-water mixture" means a mixture in which oil and water coexist, and the oil-water mixture also contains components other than oil. The oil and water contained in the oil-water mixture may be in a state of separation and coexistence, and may also be an emulsion of oil and water (oil-water emulsion). Further, the oil-water mixture may contain a part of the oil separated from the water, and may also contain a part of the oil and water emulsion.
另外,含有油水混合物為油與水之乳液時,該乳液較佳係實質上由油與水所成之乳液。在此,「實質上由油與水所成之乳液」係指乳液中除了油以及水以外,雖未限制含有其他成分,但乳液中含有95%以上、96%以上、97%以上、98%以上、99%以上、99.9%以上之油與水。而且,油水混合物所含之油與水之乳液係可為水中油型(O/W)乳液或油中水型(O/W)乳液。而且,構成乳液之油與水之比例亦無特別限制。Further, when the oil-water mixture is an emulsion of oil and water, the emulsion is preferably an emulsion substantially composed of oil and water. Here, "an emulsion substantially composed of oil and water" means that the emulsion contains not less than oil and water, but contains 95% or more, 96% or more, 97% or more, 98% of the emulsion. Above, 99% or more, 99.9% or more of oil and water. Further, the oil-water emulsion contained in the oil-water mixture may be an oil-in-water (O/W) emulsion or an oil-in-water (O/W) emulsion.

For example, the injection portion 1 may be disposed at an upper portion of the oil-water separation device 10. At this time, the injection portion 1 is particularly preferably located at the center of the upper portion of the oil-water separation device 10. This is because if the injection portion 1 is located close to the inner wall of the oil-water separation device 10, the oil-water mixture is likely to be in contact with the oil-water separating agent due to conduction along the inner wall, so that the separation efficiency of the oil is lowered. The inner diameter or the like of the injection portion 1 of the oil-water mixture can be appropriately designed in accordance with the oil-water mixture and the amount thereof to be applied in the present creation. The injection portion 1 is preferably a hose that can transport the oil-water mixture to the oil-water separation device from the outside, for example, a configuration having a hose joint.
將油水混合物注入至注入部1之手段並無特別限制,但較佳為利用泵注入油水混合物。而且,所屬技術領域中具有通常知識者可考慮較佳之揚程能力與較佳之油水混合物之注入量,適當地選擇使用之泵。The means for injecting the oil-water mixture into the injection portion 1 is not particularly limited, but it is preferred to inject the oil-water mixture by means of a pump. Moreover, those skilled in the art can appropriately select the pump to be used in consideration of the preferred head capacity and the preferred amount of oil-water mixture injected.
從注入部1所注入之油水混合物係流入槽體之上槽內。The oil-water mixture injected from the injection unit 1 flows into the groove above the tank.
油水分離裝置之槽內的空間係藉由過濾器分為槽體之上槽以及油水分離部2。流入槽體上之槽內之油水混合物係通過過濾器,流入填充有油水分離劑之油水分離部2。The space in the tank of the oil-water separation device is divided into a tank upper tank and a water-water separation unit 2 by a filter. The oil-water mixture flowing into the tank on the tank passes through the filter and flows into the oil-water separation unit 2 filled with the oil-water separating agent.
在此,於過濾器上,係使油水混合物通過油水分離部2內,但亦存有油水分離劑無法通過之大小的開口(洞)。過濾器上開口的大小係可依使用之油水分離劑而適當設定。例如,就油水分離劑而言,使用國際環境開發股份有限公司所提供之油水分離劑(AZ powder)時,開口較佳為0.2mm以下。Here, the oil-water mixture is passed through the oil-water separation unit 2 on the filter, but there are also openings (holes) of a size that the oil-water separating agent cannot pass. The size of the opening in the filter can be appropriately set depending on the oil-water separating agent to be used. For example, in the case of the oil-water separating agent, when the oil-water separating agent (AZ powder) supplied by International Environment Development Co., Ltd. is used, the opening is preferably 0.2 mm or less.
油水混合物係於填充有油水分離劑之油水分離部2中與油水分離劑接觸。藉此,將來自油水混合物之油吸收至油水 分離劑,以分離油。在此,因填充有油水分離劑之油水分離部2內的空隙率低,故油水分離部2內因流入之油水混合物而成為加壓狀態。特別是就油水分離劑而言,使用如國際環境開發股份有限公司所提供之油水分離劑(AZ powder)般空隙率低的油水分離劑時,加上油水分離劑自身的低空隙率,使油水分離部2內易成為加壓狀態。加壓狀態下之油水分離劑因該壓力使油水分離劑彼此之密度提高,油水分離劑所具有的微細孔進一步變小。如此所形成之加壓狀態下油水分離劑之微細孔,成為最特別適合於吸附在水中油型乳液中的油滴之狀態。The oil-water mixture is brought into contact with the oil-water separating agent in the oil-water separation unit 2 filled with the oil-water separating agent. Thereby, the oil from the oil-water mixture is absorbed into the oil water A separating agent to separate the oil. Here, since the void ratio in the oil-water separation unit 2 filled with the oil-water separating agent is low, the oil-water separation unit 2 is pressurized in the oil-water mixture flowing therein. In particular, in the case of the oil-water separating agent, when the oil-water separating agent having a low void ratio such as the AZ powder supplied by International Environmental Development Co., Ltd. is used, the oil-water separating agent itself is added with a low void ratio to make the oil-water The inside of the separation unit 2 is likely to be in a pressurized state. The oil-water separating agent in a pressurized state increases the density of the oil-water separating agents by the pressure, and the fine pores of the oil-water separating agent are further reduced. The fine pores of the oil-water separating agent in the pressurized state thus formed are in a state most suitable for oil droplets adsorbed in the oil-type emulsion in water.
在此,加壓狀態可依所使用之油水分離劑而適當設定,例如使用國際環境開發股份有限公司所提供之油水分離劑(AZ powder)時,較佳係0.08MPA至0.12MPA。以油水混合物之水壓實現此般之加壓狀態時,所屬技術領域中具有通常知識者可考慮油水分離裝置之構造以及大小,適當選擇具有較佳的揚程能力以及注入量之泵而達成。Here, the pressurized state can be appropriately set depending on the oil-water separating agent to be used. For example, when using an oil-water separating agent (AZ powder) supplied by International Environmental Development Co., Ltd., it is preferably 0.08 MPA to 0.12 MPA. When such a pressurized state is achieved by the water pressure of the oil-water mixture, those skilled in the art can consider the structure and size of the oil-water separation device, and appropriately select a pump having a better head capacity and injection amount.
另外,加壓狀態與非加壓狀態相比,油水分離劑之體積較佳成為35%至50%之加壓狀態,更佳為體積成為40%至45%之加壓狀態。Further, the volume of the oil-water separating agent is preferably from 35% to 50% in a pressurized state as compared with the non-pressurized state, and more preferably in a pressurized state of 40% to 45% by volume.
另外,如上述般,以油水分離劑從油水混合物分離油時,只要能夠設計使油水分離劑成為加壓狀態之空間,槽內的構造並無限定。因此,例如可以沒有槽體上槽(注入口部分與過濾器一體化等),或亦可於油水分離部之下設置過濾器,形成槽體下槽。Further, as described above, when the oil-water separating agent is used to separate the oil from the oil-water mixture, the structure in the tank is not limited as long as the oil-water separating agent can be designed to be in a pressurized state. Therefore, for example, there may be no groove on the tank (integration of the injection port portion with the filter, etc.), or a filter may be provided below the oil-water separation portion to form the groove lower groove.
另外,加壓狀態並未限定來自於油水混合物流入之水壓,以 機械的壓力等所屬技術領域中具有通常知識者習知的方法所加壓者亦為本創作所包含。例如,藉由將油水分離部2之構造以螺絲等鎖上而於油水分離部2內施加壓力之方法、對油水分離部2施重而對油水分離部2內施加壓力之方法、於油水分離部2內施加空氣壓力之方法等,亦可對油水分離劑施加壓力。In addition, the pressurized state does not limit the water pressure from the inflow of the oil-water mixture, The pressure of mechanical pressure, etc., which is well known to those skilled in the art, is also encompassed by the present invention. For example, a method of applying pressure to the oil-water separation unit 2 by locking the structure of the oil-water separation unit 2 with a screw or the like, a method of applying pressure to the oil-water separation unit 2 by weighting the oil-water separation unit 2, and separating oil and water The method of applying air pressure in the portion 2 or the like may also apply pressure to the oil-water separating agent.
本創作中可使用之油水分離劑係能夠以物理性吸收油的具有微細孔的粒子或粉末,係實質上不吸收水之粒子或粉末,而且只要是可藉由對油水分離劑施加壓力而釋放已吸收的油者,即無特別限定。此般之油水分離劑特佳為使用可取自國際環境開發股份有限公司之油水分離劑(AZ powder)。The oil-water separating agent usable in the present invention is a microporous particle or powder capable of physically absorbing oil, which does not substantially absorb water particles or powder, and can be released by applying pressure to the oil-water separating agent. The absorbed oil is not particularly limited. It is particularly preferable to use an oil-water separating agent (AZ powder) which can be taken from International Environmental Development Co., Ltd.
另外,油水分離部2內之內壁之摩擦係數係比粉末低,內壁與粉末之間之密度最容易降低。因此,油水混合物係通過這些密度低的地方,形成所謂之水道,產生未與油水分離劑接觸的地方。為抑制此般之現象,較佳係減低油水分離部2內壁的表面積,例如,較佳係使內壁的形狀成為圓形。Further, the coefficient of friction of the inner wall in the oil-water separation unit 2 is lower than that of the powder, and the density between the inner wall and the powder is most likely to decrease. Therefore, the oil-water mixture passes through these low-density places to form a so-called water channel, which produces a place where it is not in contact with the oil-water separating agent. In order to suppress such a phenomenon, it is preferable to reduce the surface area of the inner wall of the oil-water separation unit 2. For example, it is preferable to make the shape of the inner wall circular.
油水分離部2中,與油水分離劑接觸之油水混合物藉由油水分離劑吸收預定量的油,得到經分離預定量的油之油水混合物(較佳係實質上不含油之水性混合物)。In the oil-water separation unit 2, the oil-water mixture in contact with the oil-water separating agent absorbs a predetermined amount of oil by the oil-water separating agent to obtain an oil-water mixture (preferably an oil-free aqueous mixture substantially free of oil) which is separated by a predetermined amount of oil.
如此,經分離預定量的油之油水混合物,係由位於油水分離部內之回收口3回收。Thus, the oil-water mixture separated by a predetermined amount of oil is recovered from the recovery port 3 located in the oil-water separation unit.
另外,由於回收口3具有複數個使油水混合物通過至油水分離部2內,但油水分離劑無法通過的大小的開口,因此僅有經分離預定量的油之油水混合物由回收口3回收。而且,回收口3之開口大小係可與過濾器相同或相異。而且,回收口3較 佳係於離開油水分離裝置2之內壁的地方以挿入油水分離部2內的形狀設置,並且開口部分較佳為在離開油水分離部之底邊的地方開啟。這是為了避免直接回收於內壁輸送之幾乎不與油水分離劑接觸之油水混合物之故。Further, since the recovery port 3 has a plurality of openings that allow the oil-water mixture to pass through the oil-water separation unit 2, but the oil-water separating agent cannot pass, only the oil-water mixture separated by a predetermined amount of oil is recovered from the recovery port 3. Moreover, the opening size of the recovery port 3 can be the same as or different from the filter. Moreover, the recovery port 3 is more Preferably, the portion which is separated from the inner wall of the oil-water separation device 2 is disposed in the shape of the oil-water separation portion 2, and the opening portion is preferably opened at a position away from the bottom edge of the oil-water separation portion. This is to avoid direct recovery of the oil-water mixture that is transported to the inner wall and hardly contacts the oil-water separating agent.
如此,關於本創作之油水分離裝置10係可從油水混合物分離預定量的油。而且,油水混合物中所含之油量多時,可連續連接複數台油水分離裝置10,重覆分離油水混合物中之油。連結複數台油水分離裝置而使用之際,最先使用之油水分離裝置10之回收口3與接續使用之油水分離裝置10之注入口1可由軟管等連結。Thus, the oil-water separation device 10 of the present invention can separate a predetermined amount of oil from the oil-water mixture. Further, when the amount of oil contained in the oil-water mixture is large, a plurality of oil-water separation devices 10 may be continuously connected to repeatedly separate the oil in the oil-water mixture. When the plurality of oil-water separation devices are connected and used, the recovery port 3 of the oil-water separation device 10 that is used first and the injection port 1 of the oil-water separation device 10 that is used in succession can be connected by a hose or the like.
另外,依據本創作,提供用以從油水混合物分離油的油水分離系統,係具備上述之油水分離裝置10與一次處理裝置20之系統。Further, according to the present invention, an oil-water separation system for separating oil from an oil-water mixture is provided, and the system of the above-described oil-water separation device 10 and primary treatment device 20 is provided.
一次處理裝置20係於油水分離裝置10中為了使從油水混合物之油之分離更具效果,在以油水分離裝置10從油水混合物分離油之前,藉由一次處理油水分離劑處理油水混合物中大尺寸之油粒子之裝置。The primary treatment device 20 is connected to the oil-water separation device 10 in order to make the separation of the oil from the oil-water mixture more effective. Before the oil-water separation device 10 separates the oil from the oil-water mixture, the oil-water mixture is treated in a large size by treating the oil-water separating agent once. The device of oil particles.
在此,第2圖係詳細表示一次處理裝置20之一實施方式。Here, FIG. 2 is a view showing an embodiment of the primary processing device 20 in detail.
第2圖所示一次處理裝置20係於上部為開放之一次處理槽內,具備含有油水分離劑之一次處理油水分離部21、用以將一次處理油水分離部21固定於一次處理槽之固定具、回收藉由油水分離劑分離油後之油水混合物的一次處理回收口。The primary treatment device 20 shown in Fig. 2 is provided in a primary treatment tank whose upper portion is open, and includes a primary treatment oil-water separation unit 21 including a water-oil separation agent, and a fixture for fixing the primary treatment oil-water separation unit 21 to the primary treatment tank. And recovering the primary treatment recovery port of the oil-water mixture after separating the oil by the oil-water separating agent.
由於一次處理槽20之上部為開放,故可一次將大量的油水混合物注入設置於一次處理槽內的一次處理油水分離部21。Since the upper portion of the primary treatment tank 20 is open, a large amount of the oil-water mixture can be injected into the primary treatment oil-water separation unit 21 provided in the primary treatment tank at a time.
一次處理油水分離部21的構造中係成為含有一次處理油水分離劑,而可將注入一次處理油水分離部21之油水混合物中的油分離的構造。而且,一次處理油水分離部21係具有油水分離劑無法通過,但藉由油水分離劑分離油後之油水混合物可通過之構造。此般之一次處理油水分離部並未限定為下列者,但例如,可具有網籠等形狀。網籠之大小較佳係含有可一次投入下述所示之螺旋擠壓機內之量的油水分離劑之大小。而且,較佳係單一之作業員可搬運之大小。網籠的大小如上述時,則可提高作業之效率,故為較佳。例如,可於一次處理槽內同時設置複數個適當大小的網籠,作為油水分離部21。In the structure of the primary oil-water separation unit 21, the primary oil-water separating agent is contained, and the oil injected into the oil-water mixture of the primary oil-water separation unit 21 can be separated. Further, the primary treatment oil-water separation unit 21 has a structure in which the oil-water separating agent cannot pass, but the oil-water mixture obtained by separating the oil by the oil-water separating agent can pass therethrough. The primary treatment oil-water separation unit is not limited to the following, but may have a shape such as a cage. The size of the cage is preferably such that it contains the amount of the oil-water separating agent which can be fed into the screw extruder shown below. Moreover, it is preferably a size that can be carried by a single operator. When the size of the cage is as described above, the efficiency of the work can be improved, which is preferable. For example, a plurality of appropriately sized cages may be simultaneously provided in the primary treatment tank as the oil-water separation unit 21.
一次處理油水分離部21係藉由固定具固定於一次處理槽。油水混合物係可直接注入一次處理油水分離部21內。於是,於一次處理油水分離部21內所注入之油水混合物與一次處理油水分離劑接觸而分離油。此時,一次處理裝置係可主要以分離油水混合物中所含之大尺寸之油粒子為目的而使用。而且,因去除大尺寸之油粒子,大幅提升於油水分離裝置中乳液中油滴之分離效率,故為較佳。而且,本說明書中,「大尺寸之油粒子」係指油水混合物所含之油中,未與水乳化(乳液化)之油。因此,本說明書中,「大尺寸之油粒子」係例如包含形成油水混合物中所含之油中水型乳液之油相,及油水混合物中所含之與水分離而存在之油等。而且,一次處理裝置中,分離之油係不限於大尺寸之油粒子,亦可為乳液中分離之油滴。The primary treatment oil-water separation unit 21 is fixed to the primary treatment tank by a fixture. The oil-water mixture can be directly injected into the treated oil-water separation unit 21 once. Then, the oil-water mixture injected into the oil-water separation unit 21 in one treatment is brought into contact with the primary treatment oil-water separating agent to separate the oil. At this time, the primary treatment apparatus can be mainly used for the purpose of separating large-sized oil particles contained in the oil-water mixture. Further, since the large-sized oil particles are removed, the separation efficiency of the oil droplets in the emulsion in the oil-water separator is greatly improved, which is preferable. Further, in the present specification, the "large-sized oil particles" means an oil which is not emulsified (emulsiond) with water in the oil contained in the oil-water mixture. Therefore, in the present specification, the "large-sized oil particles" include, for example, an oil phase which forms an aqueous emulsion in the oil contained in the oil-water mixture, and an oil which is contained in the oil-water mixture and which is separated from the water. Further, in the primary treatment apparatus, the separated oil is not limited to large-sized oil particles, and may be oil droplets separated in the emulsion.
一次處理油水分離劑係可使用與上述油水分離裝置所用之油水分離劑相同者,亦可使用相異者。特佳為使用國際環 境開發股份有限公司所提供之油水分離劑(AZ powder)。The oil-water separating agent for the primary treatment may be the same as the oil-water separating agent used in the above-described oil-water separation device, or may be used. Tejia is using the international ring Oil and water separation agent (AZ powder) supplied by Environmental Development Co., Ltd.
在一次處理油水分離部21中油被分離後流出至一次處理槽內之油水混合物,係由一次處理回收口回收。The oil-water mixture which is discharged into the primary treatment tank after the oil is separated in the primary oil-water separation unit 21 is recovered from the primary treatment recovery port.
另外,一次處理回收口可與油水分離裝置之注入口1以軟管等連結。或者,亦可由連結用槽42等暫時性一次處理裝置,將油水混合物回收至儲存油水混合物之槽,於該槽使用泵43將油水混合物注入油水分離裝置10之注入口1。Further, the primary treatment recovery port may be connected to the injection port 1 of the oil-water separation device by a hose or the like. Alternatively, the oil-water mixture may be recovered into a tank for storing the oil-water mixture by a temporary primary treatment device such as the connection tank 42, and the oil-water mixture may be injected into the injection port 1 of the oil-water separation device 10 using the pump 43 in the tank.
另外,依據本創作,提供除了上述之油水分離裝置外又具備螺旋擠壓裝置30之用以從油水混合物分離油的油水分離系統。Further, according to the present invention, there is provided an oil-water separation system for providing oil separation from an oil-water mixture in addition to the above-described oil-water separation device.
螺旋擠壓裝置30係用以於油水分離裝置10中擠壓供以從油水混合物中分離油之油水分離劑,藉以將油回收,並且使該油水分離劑可於油之分離中再度利用之裝置。The screw extrusion device 30 is a device for squeezing the oil-water separating agent for separating oil from the oil-water mixture in the oil-water separating device 10, thereby recovering the oil, and the oil-water separating agent can be reused in the separation of the oil. .
於螺旋擠壓裝置30中,對於吸收有油之油水分離劑之擠押較佳係擠押至油水分離劑內殘留20%左右之液體左右。此般之擠押由於不會破壞油水分離劑自身之構造,故可增加可再利用次數。而且,螺旋擠壓機之構造只要為可如上述般擠押者即可,並無特別限制。In the screw extruder 30, the extrusion of the oil-water separating agent that absorbs the oil is preferably carried out to about 20% of the liquid remaining in the oil-water separating agent. In this way, the number of reusable times can be increased because the structure of the oil-water separating agent itself is not destroyed. Further, the configuration of the screw extruder is not particularly limited as long as it can be squeezed as described above.
於是,如上述般以壓力擠押油水分離劑而回收油,油水分離劑至少可再利用20次左右。藉此,可進一步抑制油水分離處理所必要之成本。Then, the oil-water separating agent is squeezed by pressure as described above to recover the oil, and the oil-water separating agent can be reused for at least about 20 times. Thereby, the cost necessary for the oil-water separation treatment can be further suppressed.
另外,藉由螺旋擠壓裝置變成可再利用狀態之油水分離劑亦可為一次處理裝置20中使用之一次處理油水分離劑。Further, the oil-water separating agent which becomes a reusable state by the screw pressing means may be the oil-water separating agent which is used once in the primary processing apparatus 20.
另外,雖未限定為以下之態樣,由有效再利用油水分離劑之 觀點,較佳為於一次處理裝置中使用在油水分離裝置中使用之油水分離劑,藉由螺旋擠壓機使一次處理裝置中使用之油水分離劑回復至可再度使用整狀態,再度於油水分離裝置中使用之方式循環的態樣。In addition, although it is not limited to the following aspects, the oil-water separating agent is effectively reused. In view of the above, it is preferred to use the oil-water separating agent used in the oil-water separation device in the primary treatment device, and the oil-water separating agent used in the primary treatment device is returned to the reusable state by the screw extruder, and then separated from the oil and water. The way the device is cycled in the way it is used.
關於使用本創作之油水分離裝置及/或一次處理裝置從油水混合物分離油後,可使油水混合物中之油,成為作為目標之油在排出基準以下,更佳係回收之油水混合物實質上不含油,或完全不含油。When the oil is separated from the oil-water mixture using the oil-water separation device and/or the primary treatment device of the present invention, the oil in the oil-water mixture can be made the target oil below the discharge standard, and the oil-water mixture recovered more preferably does not contain oil. , or completely free of oil.
油水混合物中之油之濃度,所屬技術領域中具有通常知識者可以習知之方法測定,例如,可藉由正己烷萃取物之測定而進行。The concentration of the oil in the oil-water mixture can be determined by a method known to those skilled in the art, for example, by measurement of a n-hexane extract.

以下,本創作將參照實施例而予以更詳細說明。然而,本創作可以各式態樣具體表現,不應解釋為限定於在此所記載之實施例。Hereinafter, the present creation will be described in more detail with reference to the embodiments. However, the present invention may be embodied in various forms and should not be construed as being limited to the embodiments described herein.
以下,利用圖式詳細說明實施例。Hereinafter, the embodiments will be described in detail using the drawings.
第1圖係表示從側面觀察本實施例所用之油水分離裝置之構造時之剖面示意圖。Fig. 1 is a schematic cross-sectional view showing the structure of the oil-water separation apparatus used in the present embodiment as seen from the side.
首先,使用國際環境開發公司製之油水分離劑(AZ powder)作為油水分離劑。於油水分離部內填充油水分離劑,準備油水分離裝置10。而且,在油水分離裝置10內部之上側設置過濾器(設網孔,開口0.1mm)。而且,油水分離裝置係使用全體容量為30L者。目標油水混合物係使用來自A重油之油水混合物。First, an oil-water separating agent (AZ powder) manufactured by International Environmental Development Corporation was used as an oil-water separating agent. The oil-water separation unit is filled in the oil-water separation unit, and the oil-water separation device 10 is prepared. Further, a filter (a mesh opening, opening 0.1 mm) was provided on the upper side of the inside of the oil-water separator 10. Further, the oil-water separation device uses a total capacity of 30L. The target oil-water mixture uses an oil-water mixture from A heavy oil.
另外,油水混合物中之油分以正己烷萃取物測定時為18.4ppm。另外,以下所記載之重油之濃度測定亦採相同方式進行。Further, the oil content in the oil-water mixture was 18.4 ppm as measured by the n-hexane extract. In addition, the measurement of the concentration of the heavy oil described below was also carried out in the same manner.
具體而言係如下記載方式,從來自A重油之油水混合物分離油。Specifically, the oil is separated from the oil-water mixture derived from the A heavy oil in the following manner.
從注入口1連續注入來自A重油之油水混合物。The oil-water mixture from the A heavy oil is continuously injected from the injection port 1.
此時,油水混合物係使用2吋水中泵以0.1MPA的水壓,注 入至注入口1。At this time, the oil-water mixture is pumped with a water pressure of 0.1 MPA using a 2-inch water pump. Into the injection port 1.
通過過濾器之油水混合物係均勻流入至填充有油水分離劑之油水分離部2中。The oil-water mixture passing through the filter uniformly flows into the oil-water separation unit 2 filled with the oil-water separating agent.
流入至填充有油水分離劑之油水分離部2內之油水混合物係藉由與油水分離劑接觸,使油水混合物中之油被吸收至油水分離劑中。藉此,僅有經分離預定量的油之油水混合物由回收口3回收。The oil-water mixture flowing into the oil-water separation unit 2 filled with the oil-water separating agent is brought into contact with the oil-water separating agent to cause the oil in the oil-water mixture to be absorbed into the oil-water separating agent. Thereby, only the oil-water mixture separated by a predetermined amount of oil is recovered from the recovery port 3.
由回收口3回收之油水混合物中,A重油之濃度係2.9ppm。In the oil-water mixture recovered from the recovery port 3, the concentration of the A heavy oil was 2.9 ppm.
另外,藉由連續注入油水混合物,經分離預定量的油之油水混合物可於1小時回收3600L。Further, by continuously injecting the oil-water mixture, 3,600 liters can be recovered in one hour by separating the oil-water mixture of a predetermined amount of oil.
(實施例1-2.使用2台油水分離裝置之從油水混合物分離油)(Example 1-2. Separating oil from oil-water mixture using two oil-water separation devices)
在此,對實施例1所使用之油水分離裝置之回收口3連結軟管,將該軟管與新的油水分離裝置之注入口1連結,藉以連結2台油水分離裝置。Here, the recovery port 3 of the oil-water separation device used in the first embodiment is connected to a hose, and the hose is connected to the injection port 1 of the new oil-water separator, thereby connecting two oil-water separators.
除了使用如上述般製作之2台油水分離裝置以外,係與實施例1同樣進行從含有A重油之油水混合物分離油的處理。而且,第2台油水分離裝置之構造係與實施例1所使用之油水分離裝置相同。A treatment for separating oil from an oil-water mixture containing A heavy oil was carried out in the same manner as in Example 1 except that two oil-water separation apparatuses produced as described above were used. Further, the structure of the second oil-water separation device is the same as that of the oil-water separation device used in the first embodiment.
實施例1中回收之油水混合物中重油之濃度係2.9ppm,相對於此,由第2台油水分離裝置之回收口所回收之油水混合物中重油之濃度係0.8ppm。The concentration of the heavy oil in the oil-water mixture recovered in Example 1 was 2.9 ppm. On the other hand, the concentration of the heavy oil in the oil-water mixture recovered from the recovery port of the second oil-water separator was 0.8 ppm.
(實施例2.使用一次處理裝置從油水混合物分離油)(Example 2. Separating oil from oil-water mixture using a primary treatment device)
油水混合物中含有大的油粒子時,較佳係使用一次處理裝置 20,預先進行油與水之粗略分離。When the oil-water mixture contains large oil particles, it is preferred to use a primary treatment device. 20, a rough separation of oil and water in advance.
第2圖係顯示本實施例所使用之網籠式一次處理裝置20(亦即,使用網籠作為一次處理油水分離部之一次處理裝置)之示意圖(平面圖、正面圖、以及右側面圖)以及網籠式一次處理裝置20中所使用之網籠21的正面圖。2 is a schematic view (plan view, front view, and right side view) showing the net cage type primary processing device 20 used in the present embodiment (that is, using a net cage as a primary processing device for processing the oil-water separation unit once); A front view of the cage 21 used in the cage-type primary processing device 20.
一次處理油水分離部21之網籠(大小:30cm×30cm×80cm)內,填充1kg油水分離劑。而且,使用國際環境開發公司製之油水分離劑(AZ powder)作為油水分離劑。In a cage (size: 30 cm × 30 cm × 80 cm) of the oil-water separation unit 21, 1 kg of the oil-water separating agent was filled. Further, an oil-water separating agent (AZ powder) manufactured by International Environmental Development Corporation was used as the oil-water separating agent.
於網籠式一次處理裝置20之本體的槽(容量1000L)的內部設置8個填充有油水分離劑之網籠。網籠的設置係使用鋁框之固定具。如此,準備網籠式一次處理裝置2。而且,使用來自A重油之油水混合物作為目標之油水混合物。而且,油水混合物中所含之A重油之濃度係32.3ppm。Eight cages filled with oil-water separating agent were placed inside the tank (capacity 1000 L) of the main body of the net cage type primary treatment device 20. The cage is set using an aluminum frame fixture. In this way, the net cage type primary processing device 2 is prepared. Moreover, an oil-water mixture from A heavy oil was used as the target oil-water mixture. Further, the concentration of the A heavy oil contained in the oil-water mixture was 32.3 ppm.
使用水中泵,將來自A重油之油水混合物連續注入網籠內。The oil-water mixture from the A heavy oil was continuously injected into the cage using a water pump.
流入填充有油水分離劑之網籠內之油水混合物係藉由與油水分離劑接觸,使油水混合物中之油被吸收至油水分離劑中。藉此,僅有經分離預定量的油之油水混合物由網籠排出,最後,由網籠式一次處理裝置20之一次處理回收口回收。The oil-water mixture flowing into the cage filled with the oil-water separating agent is brought into contact with the oil-water separating agent to cause the oil in the oil-water mixture to be absorbed into the oil-water separating agent. Thereby, only the oil-water mixture separated by a predetermined amount of oil is discharged from the cage, and finally, it is recovered by the treatment recovery port of the net cage type primary treatment device 20.
由一次處理回收口所回收之油水分離物中A重油之濃度係18.4ppm。The concentration of the A heavy oil in the oil-water separation body recovered from the primary treatment recovery port was 18.4 ppm.
另外,藉由將油水混合物連續注入網籠式一次處理裝置20,經分離預定量的油之油水混合物可與油水混合物之流入量相等,以每分鐘200L的量回收。Further, by continuously injecting the oil-water mixture into the net cage type primary treatment device 20, the oil-water mixture separated by a predetermined amount of oil can be equal to the inflow amount of the oil-water mixture, and is recovered in an amount of 200 L per minute.
另外,由網籠式一次處理裝置20之一次回收口所回收之油水 混合物(含有乳液),可直接與實施例1之油水混合物同樣注入油水分離裝置內。In addition, the oil and water recovered by the primary recovery port of the net cage type primary treatment device 20 The mixture (containing the emulsion) was directly injected into the oil-water separation device in the same manner as the oil-water mixture of Example 1.
(實施例3.藉由螺旋擠壓裝置從油水分離劑分離油性成分)(Example 3. Separation of oily components from oil-water separating agent by a screw extruder)
回收實施例2所使用之油水分離劑,藉由螺旋擠壓裝置進行擠壓,將油水分離劑回復至可再利用之狀態。The oil-water separating agent used in Example 2 was recovered, and extruded by a screw extruder to return the oil-water separating agent to a reusable state.
更具體而言,係使用第3圖所示之螺旋擠壓機,於螺旋擠壓機之投入口投入10L、6kg之吸附有油之油水分離劑。More specifically, 10 L and 6 kg of oil-water separating agent adsorbed with oil were placed in the screw extruder at the inlet of the screw extruder using the screw extruder shown in Fig. 3.
從投入口所投入之油水分離劑係藉由旋擰,押出至圓筒內。此時,藉由旋擰之壓力,從油水分離劑中釋放油。而且,此時於油水分離劑,係施加不致使油水分離劑所具之彈性與復原力消失之程度的不致過強的壓力。藉此,不致給予油水分離劑過度的損傷。The oil-water separating agent input from the inlet is screwed out into the cylinder. At this time, the oil is released from the oil-water separating agent by the pressure of the screwing. Further, at this time, in the oil-water separating agent, a pressure which does not cause the elasticity and the restoring force of the oil-water separating agent to disappear is not excessively applied. Thereby, excessive damage to the oil-water separating agent is not imparted.
由油水分離劑用之排出口可回收3kg之已釋放油性成分之油水分離劑。藉由油水分離劑用之排出口所回收之油水分離劑僅含少量的油,成為可再利用之狀態。3kg of the oil-water separating agent of the released oily component can be recovered from the discharge port for the oil-water separating agent. The oil-water separating agent recovered by the discharge port for the oil-water separating agent contains only a small amount of oil and is in a reusable state.
另外,在圓筒內由油水分離劑所釋放之油,可由設置於圓筒內之下部之油回收用回收口回收。回收之油量係2L。Further, the oil released from the oil-water separating agent in the cylinder can be recovered by the oil recovery recovery port provided in the lower portion of the cylinder. The amount of oil recovered is 2L.
