Description
本發明是有關於一種含油浮渣的黏度降低方法以及含油排水的黏度降低方法。 The invention relates to a method for reducing viscosity of oily dross and a method for reducing viscosity of oily drainage.
於冷軋等金屬的軋製處理中需要用以潤滑性的油、用以冷卻的水,產生含油排水。如上所述而於金屬的軋製處理等中產生的含油排水於油水分離槽中分離為水分與油分。所分離的水分可進行回收而於冷軋等中再利用,或者送至排水處理設備中。油分於分離時作為浮渣而浮起,該包含油分的浮渣(以下稱為「含油浮渣」)自油水分離槽中藉由泵進行送液,作為工業廢棄物而進行焚燒處置。 In the rolling treatment of metals such as cold rolling, oil for lubrication and water for cooling are required to produce oily drainage. The oil-containing drainage generated in the metal rolling treatment or the like as described above is separated into moisture and oil in the oil-water separation tank. The separated moisture can be recovered and reused in cold rolling or the like, or sent to a drainage treatment facility. The oil is floated as scum at the time of separation, and the scum containing oil (hereinafter referred to as "oily scum") is pumped from the oil-water separation tank by a pump, and is incinerated as industrial waste.
含油排水及含油浮渣的黏度容易由於油分的影響而變高。黏度的上升在低溫環境下顯著,特別是含油浮渣由於油分的濃度高而黏度容易變高,且對自油水分離槽中藉由泵進行送液作業造成深刻的影響。 The viscosity of oily drainage and oily scum is likely to increase due to the influence of oil. The increase in viscosity is remarkable in a low temperature environment, in particular, the oily scum is highly susceptible to high viscosity due to the high concentration of oil, and has a profound influence on the liquid feeding operation by the pump in the oil-water separation tank.
作為含油排水的油水分離處理,提出了專利文獻1及專利文獻2的技術。 The techniques of Patent Document 1 and Patent Document 2 have been proposed as the oil-water separation treatment of the oil-containing drainage.
專利文獻1是於油分離槽中,自含油廢水中分離浮起油後,未注入藥劑地於加壓浮起槽中進一步分離浮起油而藉由2個階段將浮起油除去,其後進行乳液破乳(emulsion breaking)而添加凝聚劑,使所分離的油分凝聚,於加壓浮起濃縮槽中作為浮渣而浮起且進行濃縮而除去。然而,專利文獻1僅僅著眼於油水分離,關於含油排水或含油浮渣的黏度降低並無任何考慮。 Patent Document 1 discloses that in the oil separation tank, after the floating oil is separated from the oily wastewater, the floating oil is further separated in the pressurized floating tank without injecting the chemical, and the floating oil is removed in two stages, and thereafter The emulsion breaking is performed to add an aggregating agent, and the separated oil is agglomerated, and is floated as scum in a pressurized floating concentration tank, and concentrated and removed. However, Patent Document 1 only focuses on oil-water separation, and there is no consideration regarding the viscosity reduction of oil-containing drainage or oil-containing scum.
專利文獻2揭示了使用特定的油水分離性促進劑而進行油水分離處理的方法,關於含油排水或含油浮渣的黏度降低並無任何考慮。 Patent Document 2 discloses a method of performing oil-water separation treatment using a specific oil-water separation promoter, and there is no consideration regarding the viscosity reduction of oil-containing drainage or oil-containing scum.
為了降低含油排水或含油浮渣的黏度,有效的是加溫。於專利文獻3中揭示了為了對油泥進行流體化而使操作性提高,對油泥進行加溫的方法。 In order to reduce the viscosity of oily drainage or oily scum, it is effective to increase the temperature. Patent Document 3 discloses a method of increasing the operability in order to fluidize the sludge and heating the sludge.

然而,如專利文獻3的加溫處理存在如下的問題:一系 列的步驟中的能量消耗量變大。 However, the warming process of Patent Document 3 has the following problems: The energy consumption in the steps of the column becomes larger.
而且,關於含油浮渣,亦可藉由添加水而降低黏度,但由於浮渣的水分增加而存在如下的問題:於焚燒處置時變得需要大量的助燃劑,且由於水分的存在而使含油浮渣的熱量降低,含油浮渣的再利用變困難。 Further, with regard to the oil-containing dross, the viscosity can be lowered by adding water, but the moisture of the dross increases due to the fact that a large amount of combustion improver is required at the time of incineration treatment, and oil is contained due to the presence of moisture. The heat of the scum is lowered, and the reuse of the oily scum becomes difficult.
本發明是在此種狀況下而成者,其目的在於提供並不大量消耗能量或伴隨著含油浮渣中的水分增加地使含油浮渣或含油排水的黏度降低的方法。 The present invention has been made in such a situation, and an object thereof is to provide a method for reducing the viscosity of an oil-containing dross or an oil-containing drain without causing a large amount of energy consumption or accompanying an increase in moisture in the oil-containing dross.

本發明的含油浮渣的黏度降低方法以及含油排水的黏 度降低方法可並不大量消耗能量或伴隨著含油浮渣中的水分增加地使含油浮渣及含油排水的黏度降低。 Viscosity reducing method for oily dross of the present invention and viscosity of oily drainage The degree reduction method may reduce the viscosity of the oil-containing scum and the oil-containing drainage without a large amount of energy consumption or accompanied by an increase in moisture in the oil-containing scum.
[含油浮渣的黏度降低方法] [Method for reducing viscosity of oily scum]
本發明的含油浮渣的黏度降低方法是對含油浮渣添加選自烷基二苯基醚二磺酸鹽、二烷基磺基琥珀酸鹽及聚氧伸烷基烷基醚硫酸鹽的1種以上的磺酸鹽及/或硫酸酯鹽(以下有時稱為「本發明的磺酸鹽及/或硫酸酯鹽」)。 The method for reducing the viscosity of the oil-containing dross of the present invention is to add an oil-containing dross to the salt selected from the group consisting of alkyl diphenyl ether disulfonate, dialkyl sulfosuccinate and polyoxyalkylene alkyl ether sulfate. The above sulfonate and/or sulfate salt (hereinafter sometimes referred to as "the sulfonate and/or sulfate salt of the present invention").
另外,於本發明中所謂的「含油浮渣」至少包含藉由油水分離槽而分離的油分(浮起油),進一步根據情況包含於油水分離時與油分一起同時取出的水分等油分以外的成分、及散布於含油浮渣中的水分等在油水分離後所添加的成分。 In addition, the "oil-containing scum" in the present invention includes at least an oil component (floating oil) separated by the oil-water separation tank, and further contains a component other than the oil component such as moisture which is taken out together with the oil component at the time of oil-water separation. And the components added after the separation of the oil and water, such as water dispersed in the oily scum.
本發明的含油浮渣的黏度降低方法中所可應用的含油浮渣並無特別限制。含油浮渣的來源可列舉在冷軋等金屬的軋製處理等中所產生的含油排水。 The oil-containing dross which can be applied in the viscosity reduction method of the oil-containing dross of the present invention is not particularly limited. Examples of the source of the oil-containing dross include oil-containing drainage water generated in a rolling treatment of a metal such as cold rolling.
含油浮渣中的油分並無特別限定,通常為20質量%~80質量%。 The oil content in the oil-containing dross is not particularly limited, but is usually 20% by mass to 80% by mass.
作為磺酸鹽及/或硫酸酯鹽,可使用選自烷基二苯基醚二磺酸鹽、二烷基磺基琥珀酸鹽及聚氧伸烷基烷基醚硫酸鹽的1種以上。自於如含油浮渣這樣的油分多的系統中的黏度降低優異的 方面而言,該些中適宜的是二烷基磺基琥珀酸鹽。 As the sulfonate and/or sulfate salt, one or more selected from the group consisting of alkyl diphenyl ether disulfonate, dialkyl sulfosuccinate, and polyoxyalkylene alkyl sulfate can be used. Excellent in viscosity reduction in systems with a large oil content such as oily scum In terms of aspects, dialkyl sulfosuccinates are suitable among these.
認為本發明的磺酸鹽及/或硫酸酯鹽由於阻礙油分中所含的蠟成分的結晶化而有助於含油浮渣的黏度降低。而且,認為藉由促進含油浮渣中的油滴的分散而有助於含油浮渣的黏度降低。 It is considered that the sulfonate and/or sulfate salt of the present invention contributes to a decrease in viscosity of the oil-containing dross due to inhibition of crystallization of the wax component contained in the oil component. Further, it is considered that the viscosity of the oil-containing dross is lowered by promoting the dispersion of the oil droplets in the oil-containing dross.
如上所述,本發明的磺酸鹽及/或硫酸酯鹽具有使含油浮渣的黏度降低的作用,故可使含油浮渣中所散布的水的量減少。由此而使含油浮渣中的水分減少,可削減對含油浮渣進行焚燒處置時的助燃劑的添加量。而且,藉由減少含油浮渣中的水分,可使含油浮渣的熱量變高,可再利用所回收的含油浮渣。 As described above, the sulfonate and/or sulfate salt of the present invention has an effect of lowering the viscosity of the oil-containing dross, so that the amount of water dispersed in the oil-containing dross can be reduced. Thereby, the water content in the oil-containing dross is reduced, and the amount of the combustion improver added to the incineration of the oil-containing dross can be reduced. Moreover, by reducing the moisture in the oily scum, the heat of the oily scum can be increased, and the recovered oily scum can be reused.
而且,變得無需對含油浮渣進行加熱而降低黏度,可削減蒸氣等能量的使用量。 Further, it is not necessary to heat the oil-containing dross to lower the viscosity, and it is possible to reduce the amount of energy such as steam.
本發明的磺酸鹽及/或硫酸酯鹽起到降低含油浮渣的黏度的作用,由於該作用,封入至硬的油膜中的水變得容易逃逸至油膜外,亦可促進油水分離效果。特別是烷基二苯基醚二磺酸鹽及二烷基磺基琥珀酸於油水分離作用優異的方面而言適宜。由於含油浮渣的油水分離效果,可於油水分離的每個階段減少含油浮渣的水分。 The sulfonate and/or sulfate salt of the present invention serves to reduce the viscosity of the oil-containing dross. By this action, the water enclosed in the hard oil film easily escapes to the outside of the oil film, and the oil-water separation effect can be promoted. In particular, the alkyl diphenyl ether disulfonate and the dialkyl sulfosuccinic acid are suitable in terms of excellent oil-water separation. Due to the oil-water separation effect of the oil-containing scum, the moisture of the oil-containing scum can be reduced at each stage of the oil-water separation.

於實施例1~實施例5及比較例1~比較例8中,於黏度測定後用抹刀對試管的試樣進行120秒的攪拌,將含油浮渣與藥劑加以混合後,於20℃的環境下進行18小時的靜置,藉由目視觀察油水分離的狀態。其結果,將可觀察水層為整體的1/5~1/4的情況作為「○」,將可觀察水層不足1/5的情況作為「△」,將油水未分離而無法觀察水層的情況作為「×」。將結果表示於表1中。 In Examples 1 to 5 and Comparative Examples 1 to 8, the sample of the test tube was stirred with a spatula for 120 seconds after the viscosity measurement, and the oil-containing dross was mixed with the drug at 20 ° C. The environment was allowed to stand for 18 hours under the environment, and the state of oil-water separation was visually observed. As a result, the case where the water layer is observed as 1/5 to 1/4 of the whole is regarded as "○", and the case where the water layer is less than 1/5 is observed as "△", and the oil and water are not separated and the water layer cannot be observed. The situation is "X". The results are shown in Table 1.
根據表1的結果可知:添加有選自烷基二苯基醚二磺酸鹽、二烷基磺基琥珀酸鹽及聚氧伸烷基烷基醚硫酸鹽的磺酸鹽及/或硫酸酯鹽的實施例1~實施例5可大幅降低最初的含油浮渣的黏度(7.6Pa.s)。而且,實施例1、實施例3~實施例5的磺酸鹽及/或硫酸酯鹽的油水分離效果亦優異。 According to the results of Table 1, it is known that a sulfonate and/or a sulfate selected from the group consisting of alkyl diphenyl ether disulfonate, dialkyl sulfosuccinate and polyoxyalkylene alkyl sulfate is added. Examples 1 to 5 of the salt can greatly reduce the viscosity (7.6 Pa.s) of the initial oil-containing dross. Further, the sulfonate and/or sulfate salt of Example 1, Example 3 to Example 5 was also excellent in oil-water separation effect.
