Description

오일 함유 폐수 처리장치{Disposal device of waste water with oil}Disposal device of waste water with oil

본 고안은 스트립 연마라인에서 발생되는 오일 함유 폐수를 처리하는 처리설비에 관한 것으로, 침전조 상부로 부유되는 오일을 효과적으로 처리하고 배관 등의 막힘을 방지할 수 있도록 된 오일 함유 폐수 처리장치에 관한 것이다.The present invention relates to a treatment facility for treating oil-containing wastewater generated in a strip polishing line, and relates to an oil-containing wastewater treatment device that is capable of effectively treating oil suspended in an upper portion of a sedimentation tank and preventing clogging of piping.

일반적으로 철강을 제조하는 과정에서 다양한 부산물(스케일, 내화물, 유분, 산화규소, 니켈, 크롬 등)이 찌꺼기로 배출되어 나오는 데, 이러한 오염물질은 폐수 처리기술인 여과, 침전, 중화 등 약품 처리에 의한 물리 화학적 방법을 통해 처리되게 된다.In general, various by-products (scale, refractory, oil, silicon oxide, nickel, chromium, etc.) are discharged as waste during steel manufacturing process. These pollutants are produced by chemical treatment such as filtration, sedimentation, and neutralization. It is treated through physicochemical methods.

폐수 처리는 비용해성 물질을 물과 분리시키는 데 그 목적을 두며 처리방법으로는 폐수에 각 약품을 투입, 중화처리하여 이물질과 깨끗한 물로 분리시킨 후 아주 작은 알갱이의 이물질(콜로이드)은 침전조에서 고속 침강재를 투입하여 이물질을 응결시켜 이물질인 슬러지는 침전시키고 깨끗한 물(상등수)는 배출시키게 된다.Wastewater treatment aims to separate insoluble substances from water.In the treatment method, each chemical is injected into the wastewater, neutralized, and separated into foreign matter and clean water, and very small grains (colloids) are settled in the sedimentation tank at high speed. The ash is added to condense foreign matters, and the sludge, which is foreign matters, is settled and the clean water (supernatant) is discharged.

특히, CGL(coil grinding line)설비에서 발생되는 폐수에는 연마유와 같은 오일이 다량 함유되어 있는 데, 이러한 오일은 약품 투입 과정 중 폐수에서 분리되어져 침전조 상부로 부유되므로 별도의 처리장치를 이용하여 처리하도록 되어 있다.In particular, the wastewater generated from the CGL (coil grinding line) facility contains a large amount of oil such as abrasive oil, which is separated from the wastewater during the chemical input process and suspended above the sedimentation tank so that it is treated using a separate treatment device. It is supposed to be.

종래의 오일 처리를 위한 장치를 살펴보면 도 5에 도시된 바와 같이, 원통형의 침전조(100) 내부에 설치되는 내부원통(110)과, 내부원통(110) 중앙의 구동모터(130)의 축에 연결된 회전샤프트(120)에 설치되어 폐수 상부에 떠있는 부유 오일을 걷어내기 위한 스크레이퍼(140)와 오일이 담겨지는 오일거터(150) 및 침전조(100)의 내부원통(110) 내부로 폐수를 유입시키기 위한 이송관(160)과, 상기 오일거터(150)에 수집되는 오일을 배출시키기 위한 배출관(170) 등으로 이루어진다.Looking at the conventional oil treatment apparatus as shown in Figure 5, connected to the shaft of the inner cylinder 110 and the drive motor 130 in the center of the inner cylinder 110, which is installed inside the cylindrical settling tank 100 Installed on the rotary shaft 120 to allow the wastewater to flow into the inner cylinder 110 of the oil gutter 150 and the sedimentation tank 100 in which the scraper 140 and oil are contained to lift off the floating oil floating on the upper portion of the wastewater. It consists of a transfer pipe 160 for, and a discharge pipe 170 for discharging the oil collected in the oil gutter 150 and the like.

또한 유입관(160) 내부로 에어관(180)이 설치되어 에어와 폐수가 같이 유입되게 되는 데, 종래에는 에어의 힘에 의해 침전조의 폐수가 심하게 출렁거려 부유오일 모음 거터로 상등수가 넘쳐 유입되는 문제점이 발생되었다.In addition, the air pipe 180 is installed inside the inlet pipe 160 so that the air and the waste water are introduced together. In the related art, the wastewater of the sedimentation tank is slumped by the force of the air, and the supernatant is overflowed into the floating oil collection gutter. A problem has occurred.

즉, 침전조 내부로 아무 장치 없이 바로 에어와 폐수가 유입되어 부상되어야 하나 에어가 폐수 속에 포함되어 있는 오일을 효과적으로 흡착하여 부유시키지 못하며, 폭기되는 에어의 힘에 의해 침전조 상부의 수면이 상당히 출렁이게 되어 스크레이퍼에 보유오일만이 거터 내부로 걷어지는 것이 아니라 상등수도 거터 내부로 유입되어져 배출관을 통해 빠져나가게 됨에 따라 재처리 비용이 증가되는 것이다.In other words, air and wastewater should be introduced and floated without any device into the sedimentation tank, but air cannot effectively adsorb and float the oil contained in the wastewater, and the surface of the sedimentation tank is greatly shaken by the force of the aerated air. Not only the holding oil in the scraper walks inside the gutter, but also the reprocessing cost increases as the supernatant water flows into the gutter and exits through the discharge pipe.

또한 도 5에서와 같이, 침전조(100) 하부에는 가라앉은 슬러지를 이송시키기 위한 이송배관(190)과 펌프(200)가 설치되어 있는 데, 이송배관(190)이 덩어리진 슬러지에 의해 막히게 되는 경우에는 펌프(200) 출측 배관 밸브를 잠그고 에어를 공급하여 관통하게 되는 데, 순간적으로 에어가 폭기되므로서 침전조(100) 하부에 누적되어 있던 슬러지가 부유되어 상등수와 같이 오일거터(150)를 통해 유출되는 문제점이 발생되었다.In addition, as shown in Figure 5, the lower portion of the settling tank 100 is provided with a transfer pipe 190 and a pump 200 for transferring the settled sludge, when the transfer pipe 190 is blocked by agglomerated sludge In the pump 200, the outlet valve is shut off and the air is supplied. The sludge accumulated in the lower part of the sedimentation tank 100 is suspended due to the aeration of the air and flows out through the oil gutter 150 as the supernatant water. The problem arises.

이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 오일이 함유되어 있는 폐수의 오일을 효과적으로 처리하고 침전조 하부에 누적되어 있는 슬러지를 안정적이고 원활하게 처리하여 수질환경 오염 방지 및 폐수 재처리 비용을 절감할 수 있도록 된 오일 함유 폐수 처리장치를 제공함에 그 목적이 있다.In order to solve the problems described above, the present invention effectively treats oil in wastewater containing oil and stably and smoothly treats sludge accumulated in the lower part of the sedimentation tank to prevent water pollution and reprocess the wastewater. It is an object of the present invention to provide an oil-containing wastewater treatment apparatus that can reduce costs.

본 고안에 따르면, 부유통(30) 중앙에 설치되어 내부로 슬러지 스크레이퍼(20)를 회전시키기 위한 샤프트(18)가 삽입되는 고정관(38)은 내부원통(22) 상부까지 연장되는 데, 이 고정관(38) 상단에는 뒤에 설명되는 거터부가 고정설치되게 된다.According to the present invention, the fixed tube 38 is installed in the center of the floating cylinder 30 is inserted into the shaft 18 for rotating the sludge scraper 20 into the inner cylinder 22 is extended to the upper, this fixed tube (38) On the upper end, the gutter portion described later is fixedly installed.

상기 거터부는 도 1과 도 3에 도시된 바와 같이, 내부원통(22) 상부로 부유된 오일을 걷어내기 위한 것으로, 부유통(30)의 고정관(38) 상부에 부착설치되고 내부원통(22) 상부에 위치하며 표면에 다수개의 홀(52)이 형성된 원판(50)과, 상기 구동모터(16)의 샤프트(18)에 설치되어 원판(50) 표면을 쓸어 홀(52)을 통해 나온 오일을 걷어주기 위한 오일 스크레이퍼(54), 원판(50) 일측에 방사방향으로 절결된 슬릿(56)을 통해 낙하되는 오일을 받아 배출관(60)을 통해 침전조(10) 외부로 배출시키기 위한 오일거터(58)로 이루어진다.As shown in Figure 1 and 3, the gutter portion is for removing the oil suspended in the upper portion of the inner cylinder 22, is attached to the fixed tube 38 of the floating cylinder 30, the inner cylinder 22 A disk 50 having a plurality of holes 52 formed on the surface thereof, and installed in the shaft 18 of the driving motor 16 and sweeping the surface of the disk 50 to discharge oil through the holes 52. Oil scraper 54 for walking the oil gutter for receiving the oil falling through the slit 56 cut in the radial direction on one side of the disc 50, discharged through the discharge pipe 60 to the outside of the settling tank 10 ( 58).

원판(50)은 고정관(38) 상부에 형성된 플랜지(40)와 보울트 체결하고, 바람직하게는 내부원통(22) 내주면으로 서포터(62)를 부착설치하여 서포터(62)에 놓여지는 원판(50)과 보울트 체결하므로서 체결력을 강화시킨다.The disc 50 is bolted with the flange 40 formed on the fixing pipe 38, and preferably the disc 50 placed on the supporter 62 by attaching and installing the supporter 62 to the inner circumferential surface of the inner cylinder 22. The tightening force is strengthened by tightening the bolt with.

여기서 상기 원판(50)은 상등수면에 접촉될 듯 말 듯 하게 설치되어, 원판(50) 표면에 형성된 홀(52)을 통해 오일만이 빠져나오게 된다.Here, the disc 50 is installed so as to be in contact with the upper surface of the water, only the oil is drawn out through the hole 52 formed in the surface of the disc 50.

한편, 본 고안은 침전조(10) 바닥에 쌓이게 되는 슬러지 처리시 슬러지가 슬러지이송배관 내부에서 막히게 되는 경우 이를 제거하기 위한 제거부를 더욱 포함한다.On the other hand, the present invention further includes a removal unit for removing the sludge when the sludge is accumulated in the sludge transport pipe during the sludge treatment to be accumulated on the bottom of the settling tank (10).

이를 위해 상기 제거부는 도 3에 도시된 바와 같이, 침전조(10) 하부에 형성된 슬러지투입구(70)에 연결되어 슬러지를 이송시키기 위한 이송배관(72) 내부에 길이방향으로 놓여져 양단이 회동가능하게 지지되는 회전축(74)과, 이 회전축(74)에 일정간격으로 배열 설치되는 십자형 철심(76), 상기 회전축(74)에 연결되어 회전축(74)을 회전시키기 위한 구동모터(78)로 이루어진다.To this end, the removal unit is connected to the sludge inlet 70 formed at the bottom of the settling tank 10, as shown in Figure 3 is placed in the longitudinal direction inside the conveying pipe 72 for transporting the sludge so that both ends are rotatably supported. It consists of a rotating shaft 74, a cross-shaped iron core 76 is arranged at a predetermined interval on the rotary shaft 74, the drive motor 78 is connected to the rotary shaft 74 to rotate the rotary shaft 74.

이에 따라 회전축(74)에 설치된 십자형 철심(76)이 이송배관(72) 내부의 슬러지를 파쇄하여 막힘을 제거하게 된다.Accordingly, the cross iron core 76 installed on the rotary shaft 74 breaks the sludge in the transfer pipe 72 to remove the blockage.

이하 본 고안의 작용에 대해 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

오일을 함유하고 있는 폐수는 폐수 이송관(12) 일측에 연결설치된 에어관(24)을 통해 투입되는 에어와 함께 내부원통(22)에 내부에 설치된 부유통(30)으로 유입되는 데, 부유통(30)에 의해 에어와 폐수가 균등하게 퍼지면서 공급된 에어와 폐수가 골고루 혼합되게 된다.Waste water containing oil flows into the floating cylinder 30 installed inside the inner cylinder 22 together with the air introduced through the air pipe 24 connected to one side of the wastewater conveying pipe 12, By 30, the air and the wastewater are evenly spread, and the supplied air and the wastewater are evenly mixed.

따라서 오일은 에어 기포 표면에 묻게 되고 기포 표면에 묻은 오일과 폐수가 분리되면서 부유통(30) 상부에 형성된 홀(32)을 통해 내부원통(22)으로 균일하게 빠져나가게 된다.Therefore, the oil is buried on the surface of the air bubble and the oil and waste water on the surface of the bubble is separated out evenly into the inner cylinder 22 through the hole 32 formed in the upper portion of the float (30).

이와 같이 에어와 폐수가 일차적으로 부유통(30)에 투입되어 섞어지고 홀(32)을 통해 일정량씩 빠져나감에 따라 폐수속에 포함되어 있는 오일을 에어가 효과적으로 흡착할 수 있고, 특히 에어가 폭기된 경우 그 충격이 폐수 상부까지 전달되지 않아 상등수가 출렁이는 것을 방지할 수 있게 된다.As such, the air and the wastewater are first introduced into the floating container 30, mixed with each other, and the air is effectively adsorbed to the oil contained in the wastewater as the water is discharged by a predetermined amount through the hole 32. In particular, the air is aerated. In this case, the impact is not transmitted to the upper part of the waste water, thereby preventing the supernatant from slumping.

오일 흡착 에어는 부유통(30)의 홀(32)을 빠져나와 내부원통(22) 상부로 부유되는 데, 내부원통(22) 상부에 설치된 원판(50)이 상등수의 출렁임을 방지하게 되고, 부유된 오일만이 원판(50)에 형성된 홀(52)을 통해 원판(50) 윗면으로 흘러나오게 된다.The oil adsorption air exits the hole 32 of the floating cylinder 30 and floats to the upper portion of the inner cylinder 22. The disc 50 installed on the upper portion of the inner cylinder 22 prevents the supernatant from swelling. Only the used oil flows to the upper surface of the disk 50 through the hole 52 formed in the disk 50.

이때, 원판(50) 상부에 밀착되어 있는 오일 스크레이퍼(54)가 구동모터(16)의 작동에 의해 회전되면서 원판(50) 윗면을 일방향으로 쓸어 원판(50)의 홀(52)을 통해 나온 오일을 걷어내게 된다.At this time, the oil scraper 54 in close contact with the top of the disc 50 is rotated by the operation of the drive motor 16, the oil exits through the hole 52 of the disc 50 by sweeping the top surface of the disc 50 in one direction. Kick off.

스크레이퍼(54)에 의해 걷어진 오일은 스크레이퍼(54)가 일방향으로 회전함에 따라 밀려나가 원판(50)의 슬릿(56)을 통해 슬릿(56) 하부에 설치되어 있는 오일 거터(58)에 담아지게 되고, 걷어진 오일은 거터(58)에 연결된 배출관(60)을 통해 빠져나가게 된다.The oil collected by the scraper 54 is pushed out as the scraper 54 rotates in one direction so that the oil is collected in the oil gutter 58 installed below the slit 56 through the slit 56 of the disc 50. And, the oil is drawn out through the discharge pipe 60 is connected to the gutter (58).

따라서 원판(50)에 의해 상등수의 출렁임이 방지되므로서 오일만을 거터(58)로 걷어낼 수 있게 되는 것이다.Therefore, only the oil can be rolled out to the gutter 58 by preventing the supernatant from being slumped by the disc 50.

한편, 침전조(10) 바닥에 쌓이는 슬러지는 샤프트(18)에 연결된 슬러지 스크레이퍼(20)가 구동모터(16)의 작동에 의해 회전되면서 침전조(10) 바닥의 샤프트(18) 하부에 형성된 슬러지투입구(70)를 통해 슬러지 이송배관(72)으로 빠져나가게 되는 데, 덩어리진 슬러지 등은 이송배관(72)에 설치된 십자형 철심(76)에 의해 파쇄되어 이송배관(72)의 막힘이 방지되게 된다.On the other hand, the sludge accumulated on the bottom of the settling tank 10 is rotated by the operation of the drive motor 16, the sludge scraper 20 connected to the shaft 18, the sludge inlet formed in the lower shaft 18 of the bottom of the settling tank 10 ( The sludge is passed through the sludge transfer pipe 72 through 70, and the lumped sludge or the like is crushed by the cruciform iron core 76 installed in the transfer pipe 72 to prevent the blockage of the transfer pipe 72.

즉, 슬러지 이송펌프(80)가 가동되면 구동모터(16)에 전원이 인가되면서 구동모터(16)에 연결된 회전축(74)이 회전하게 되고, 상기 회전축(74)에 설치된 십자형 철심(76)이 이송배관(72) 내부에서 회전하게 된다.That is, when the sludge feed pump 80 is operated, power is applied to the drive motor 16 to rotate the rotary shaft 74 connected to the drive motor 16, and the cross iron core 76 installed on the rotary shaft 74 is rotated. It is rotated in the transfer pipe (72).

따라서 이송배관(72)이 막히거나 내부로 덩어리진 슬러지가 유입된 경우 십자형 철심(76)이 이를 파쇄함으로서 이송배관(72)의 막힌 부분을 뚫어주게 된다.Therefore, when the conveying pipe 72 is blocked or the sludge agglomerated into the inside, the cross-shaped iron core 76 breaks it so as to pierce the blocked portion of the conveying pipe 72.

여기서 상기 슬러지 이송펌프(80)가 가동정지되면 구동모터(78)도 작동을 멈추고 정지하게 된다.Here, when the sludge feed pump 80 is stopped operating, the driving motor 78 also stops and stops operating.

이상 설명한 바와 같이 본 고안에 의한 오일 함유 폐수 처리장치에 의하면, 폐수에 함유된 오일을 효과적으로 부유시킬 수 있고, 상등수의 유출을 방지할 수 있게 되어 환경이 오염되는 것을 방지할 수 있다.As described above, according to the oil-containing wastewater treatment apparatus according to the present invention, it is possible to effectively float the oil contained in the wastewater and to prevent the outflow of the supernatant water, thereby preventing the environment from being polluted.

또한 침전조 상부로 부유되는 순수한 부유오일만 처리하므로 재처리 비용을 절감시킬 수 있다.In addition, since only the pure floating oil suspended in the upper part of the settling tank can reduce the reprocessing cost.

뿐만아니라 폐수 처리를 원활하게 하여 연속작업이 가능함에 따라 제품 생산량 저하를 방지할 수 있다.In addition, the waste water treatment can be performed smoothly to prevent continuous product production.
