Description
본 발명은 금속부품등을 세정할 때 발생되는 폐수를 여과시켜 폐수에 포함된 기름과 이물질을 분리함과 동시에 기름에 포함된 세정액을 분리하여 재사용할 수 있도록 한 유수분리용 필터에 관한 것이다.The present invention relates to an oil-water separation filter for filtering wastewater generated when washing metal parts, so as to separate oil and foreign substances contained in the wastewater and to separate and reuse the cleaning liquid contained in the oil.
일반적으로, 금속부품등을 세정할 때 사용되는 세척제는 염소계 탄화수소, 석유계 용제등으로서 이들 약품은 오존층을 파괴하고 수질오염등을 발생시키는 공해물질로 처리상 많은 문제점을 가지고 있었다.In general, the cleaning agents used to clean metal parts and the like are chlorine hydrocarbons, petroleum solvents, and the like, and these chemicals are pollutants that destroy the ozone layer and cause water pollution.
따라서, 종래 세정폐수를 정수하기 위해서는 별도의 복잡한 기계설비로 된 유수분리장치와 폐수처리장치등을 설비해야 되므로서 막대한 경비부담을 가지게 되는 폐단이 있었다.Therefore, in order to purify the waste water of the prior art, there has been an enormous cost burden because it requires the installation of a separate oil and water separator and a waste water treatment device.
본 발명은 이와 같은 점을 감안하여 안출한 것으로 물과 친화력이 강한 극세섬유에 이온막을 형성시킨 필터를 제공하여 세정폐수를 유수분리하고, 세정액은 재사용할 수 있도록 하므로서 종래의 폐단을 해소한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been made in view of such a point to provide a filter in which an ionic membrane is formed on microfibers having strong affinity with water to separate oil and water from washing waste water and to reuse the washing liquid, thereby eliminating the conventional waste. When described in detail based on the accompanying drawings as follows.
제1도는 본 발명의 사시도.1 is a perspective view of the present invention.
제2도는 본 발명의 단면도.2 is a cross-sectional view of the present invention.

본 발명의 필터(1)는 내부중심에 구멍(2)이 관통된 원통형상으로 구성되어 유수분리기의 탱크내에 설치되는 것으로 내외면에 부직포(3)의 내부에 폴리에틸렌등과 같이 물과 친화력이 강하며 압력부하가 적고 내약품성을 가지는 재질의 극세섬유에 이온막을 형성시킨 여과포(4)(4')를 다수층 적층시켜 상하부에 캡(5)(5')을 고정시킨 구조로 되어 있다. 이와 같이 된 본 발명은 유수분리기의 탱크내에 설치되어 세정공정에서 배출되는 세정액과 오일의 혼합 폐수가 필터(1)의 부직포(3)를 통해 여과포(4)(4')를 거친 후 다시 내측의 부직포(3)를 통해 구멍(2)으로 배출되는데 이 과정에서, 여과포(4)(4')는 물과 친화력이 강하며 압력부하가 적고 내약품성을 가지는 폴리에틸렌과 같은 극세섬유에 이온막이 형성된 구조로 되어 있으므로 세정액과 오일이 혼합된 세정폐수가 부직포(3)를 통해 여과포(4)(4')를 통과할 때 여과포(4)(4')의 강한 친화력에 의해 에멀죤상태로 오일을 끌어모으는 힘으로 오일의 작은 입자가 큰방울의 입자로 뭉쳐져 완전한 오일로 만들어지면서 내부의 부직포(3)를 통해 중심구멍(2)으로 통과되어 나오게 되고, 구멍(2)으로 여과되어 나온 기름은 세정액보다 비중이 약해 세정액의 상부에 뜨게 되므로 이 상태에서 세정액과 오일을 쉽게 분리하여 세정액은 재사용하고 오일은 폐기하면 되는 것으로 본 발명의 필터는 실험결과 유수분리 능력이 50-60℃에서 오염기존의 99% 이상이 제거되는 것으로 국립공업기술원의 연구결과 입증되었다.The filter 1 of the present invention has a cylindrical shape with a hole 2 penetrated at an inner center thereof and is installed in a tank of an oil / water separator, and has a strong affinity with water, such as polyethylene, inside the nonwoven fabric 3 on the inner and outer surfaces thereof. It has a structure in which caps (5) and (5 ') are fixed to the upper and lower parts by laminating a plurality of layers of filter cloth (4) and (4') in which an ion membrane is formed on microfibers having a low pressure load and chemical resistance. Thus, the present invention is installed in the tank of the oil / water separator and the mixed wastewater of the washing liquid and oil discharged from the washing process passes through the filter cloth (4) (4 ') through the nonwoven fabric (3) of the filter (1) and then again inside The nonwoven fabric (3) is discharged into the hole (2). In this process, the filter cloth (4) (4 ') has a structure in which an ion membrane is formed on ultrafine fibers such as polyethylene having a high affinity with water, a low pressure load, and chemical resistance. As the cleaning waste water mixed with the cleaning liquid and the oil passes through the filter cloth (4) (4 ') through the nonwoven fabric (3), the oil is attracted to the emulsion state by the strong affinity of the filter cloth (4) (4'). As a result of the gathering force, the small particles of oil aggregate into large droplets to form a complete oil, which passes through the inner nonwoven fabric 3 to the center hole 2, and the oil filtered out of the hole 2 is better than the cleaning liquid. Low specific gravity, floating on top of cleaning solution Therefore, in this state, the cleaning liquid and oil can be easily separated, the cleaning liquid can be reused, and the oil can be discarded. As a result of the experiment, the filter of the present invention can remove more than 99% of the existing contaminants at 50-60 ° C. Has been proven.
이와 같이 본 발명은 세정폐수나 각종산업 공장에서 배출되는 산업폐수의 오일과 물을 화공약품을 사용치 않고 여과포(4)(4')를 통과시켜 분리하므로 2차적인 환경오염을 막고 분리된 오일과 물을 재사용할 수 있으므로 원가절감의 효과가 있는등 우수한 발명이다.As described above, the present invention separates oil and water of washing wastewater or industrial wastewater discharged from various industrial plants through the filter cloth (4) (4 ') without using chemicals, thereby preventing secondary environmental pollution and separating oil. And because the water can be reused is an excellent invention, such as cost reduction effect.
