Description

폐용액 처리장치{Apparatus for treating waste solution}Apparatus for treating waste solution

본 발명은 폐용액 처리장치에 관한 것으로, 폐용액에 함유된 물을 제거함으로써 겔형태로 고형화된 폐용액만이 폐용액 저장탱크에 남게 하여 폐용액에 저장된 폐용액의 부피를 줄여주기 때문에 폐용액을 수시로 폐기처리해주지 않아도 되게 하는 폐용액 처리장치에 관한 것이다. The present invention relates to a waste solution processing apparatus, and because only the waste solution solidified in a gel form by removing the water contained in the waste solution remains in the waste solution storage tank to reduce the volume of the waste solution stored in the waste solution waste solution It relates to a waste solution processing apparatus that does not have to be disposed of at any time.

제철소의 압연설비에서 압연되어 생산된 강판은 도금공정을 거치게 된다. The steel sheet produced by rolling in a steel mill is subjected to a plating process.

도금된 강판(100)은 도1에 도시된 바와 같은 수지코팅설비(110)를 지나면서 수지코팅된다. The plated steel sheet 100 is resin coated while passing through the resin coating equipment 110 as shown in FIG.

수지코팅설비(110)에는 수지용액 처리탱크(120)가 수지용액 공급관(130)과 수지용액 회수관(140)에 의해서 연결되어, 수지코팅설비(110)에 수지코팅액을 공급하고, 코팅되고 남은 수지코팅액을 회수하도록 되어 있다. The resin coating equipment 110 is connected to the resin solution processing tank 120 by the resin solution supply pipe 130 and the resin solution recovery pipe 140 to supply the resin coating solution to the resin coating equipment 110, and to remain coated and remaining. It is intended to recover the resin coating liquid.

이러한 수지코팅액의 공급과 회수 동안에 수지용액 처리탱크(120)에 담긴 수지코팅액은 수지코팅작업 동안에 강판(100) 등이나 수지코팅설비(110)에 의해서 또는 수지코팅설비(110)의 플러싱작업으로 인한 폐수 등의 유입으로 폐용액으로 바뀌 게 된다. During the supply and recovery of the resin coating liquid, the resin coating liquid contained in the resin solution processing tank 120 may be formed by the steel plate 100 or the like during the resin coating operation or by the resin coating equipment 110 or by the flushing of the resin coating equipment 110. Inflow of wastewater, etc., will cause the waste solution to change.

일정기간 사용되어 폐용액으로 바뀐 수지코팅액은 수지용액 처리탱크(120)에 연결된 드레인관(150)을 통해 폐용액 저장탱크(1)로 이동되어 저장된다. The resin coating solution used for a predetermined time is changed into the waste solution and is moved to the waste solution storage tank 1 through the drain pipe 150 connected to the resin solution processing tank 120 and stored.

폐용액 저장탱크(1)에 저장된 폐용액 수지코팅액은 도1에 도시된 바와 같이 폐용액 저장탱크(1)의 하부에서는 침전되어 겔형태로 고형화되고, 상부에서는 물이 함유된 상태로 있게 된다. The waste solution resin coating liquid stored in the waste solution storage tank 1 is precipitated at the lower portion of the waste solution storage tank 1 and solidified in a gel form, as shown in FIG.

종래에 폐용액 저장탱크(1)에 저장된 폐용액은 도1에 도시된 바와 같이 물 처리관(160)을 통해 수처리설비로 보내어져 처리되게 된다. Conventionally, the waste solution stored in the waste solution storage tank 1 is sent to the water treatment facility through the water treatment pipe 160 to be treated as shown in FIG.

폐용액 저장탱크(1)의 하부에는 겔형태로 고형화된 폐용액이 위치하기 때문에, 수처리설비로 보내어질 때 겔형태로 고형화된 폐용액이 관 등을 막게 되고, 수처리설비에서 처리시 여러 종류의 처리용액과 화학반응을 일으켜 수처리설비를 오염시키는 등의 문제점이 있었다. Since the waste solution solidified in the form of gel is located under the waste solution storage tank 1, the waste solution solidified in the form of gel blocks the pipe when it is sent to the water treatment facility. There was a problem such as causing a chemical reaction with the treatment solution to contaminate the water treatment equipment.

따라서, 일정기간이 지나게 되면 폐용액 저장탱크(1)의 하부에 위치하는 겔형태로 고형화된 폐용액은 도1에 도시된 바와 같이 폐용액 저장탱크(1)에 형성된 흡입구멍(3)에 덮힌 덮개(2)를 열고 흡입구멍(3)에 진공흡입관(4)을 삽입하여 흡입하는 방법으로 폐기처리해야만 했다. Therefore, after a certain period of time, the waste solution solidified in a gel form located under the waste solution storage tank 1 is covered by the suction hole 3 formed in the waste solution storage tank 1 as shown in FIG. It was necessary to dispose of the cover 2 by opening the cover 2 and inserting the vacuum suction tube 4 into the suction hole 3.

종래 이와 같은 겔형태로 고형화된 폐용액의 폐기처리시에는 겔형태로 고형화된 폐용액만을 폐기처리하지 못하기 때문에 물이 함유된 폐용액도 겔형태로 고형화된 폐용액과 같이 폐기처리되었다. Conventionally, when the waste solution solidified in the gel form is not disposed, only the waste solution solidified in the gel form cannot be disposed, and the waste solution containing water was also disposed in the same manner as the waste solution solidified in the gel form.

따라서, 폐기처리되는 양이 많을뿐더러, 폐용액 저장탱크(1)가 빨리 차게 되 어 수시로 상기와 같은 폐기처리를 해야만 한다는 문제점이 있었다. Therefore, there is a problem that the waste solution storage tank 1 fills up quickly, and the waste solution storage tank 1 needs to be discarded as often.

이에 의하여 폐용액 폐기처리비용이 많이 들고, 작업자의 업무부하가 증가하며, 환경오염을 일으킨다는 문제점이 있었다. As a result, waste solution disposal costs are high, the work load of workers increases, and there is a problem that causes environmental pollution.

본 발명은 상기한 문제점을 해결하고자 창출된 것으로, 본 발명의 목적은 폐용액 저장탱크에 저장된 폐용액에서 물을 제거함으로써 겔형태로 고형화된 폐용액 만을 폐용액 저장탱크에 남게 하여 폐용액 저장탱크에 저장된 폐용액을 수시로 폐기처리하지 않아도 되게 하는 폐용액 처리장치를 제공하는 것이다.The present invention has been made to solve the above problems, an object of the present invention is to remove the water from the waste solution stored in the waste solution storage tank to leave only the waste solution solidified in the gel form in the waste solution storage tank waste solution storage tank It is to provide a waste solution processing apparatus that does not have to be disposed of at any time the waste solution stored in.

이하, 첨부도면을 참조로 하여 본 발명을 상세하게 설명한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도2는 본 발명에 따른 페용액 처리장치가 장착된 폐용액 저장탱크의 일실시예를 나타내는 도면이고, 도3은 본 발명에 따른 폐용액 처리장치의 일실시예의 폐용액 처리수단을 나타내는 도면이며, 도4a 내지 도4d는 본 발명에 따른 폐용액 처리장치의 일실시예가 장착된 폐용액 저장탱크에서 폐용액이 처리되는 것을 나타내는 도면이다.2 is a view showing an embodiment of a waste solution storage tank equipped with a waste solution treatment apparatus according to the present invention, Figure 3 is a view showing the waste solution treatment means of an embodiment of the waste solution treatment apparatus according to the present invention. 4A to 4D are views showing that the waste solution is processed in the waste solution storage tank equipped with the embodiment of the waste solution treatment apparatus according to the present invention.

도시된 바와 같이 본 발명에 따른 폐용액 처리장치(10)는 도금공정의 수지코팅에 사용된 폐용액이 담겨진 폐용액 저장탱크(1) 내에 위치하여 폐용액에서 물을 제거하도록 구성된 폐용액 처리수단(20)과, 폐용액 처리수단(20)에 공기를 공급하도록 폐용액 처리수단(20)에 연결된 공기 공급수단(30) 및, 폐용액 처리수단(20)에 의해서 제거된 물이 배출되도록 폐용액 처리수단(20)에 연결된 물 배출수단(40)을포함하여 구성된다. As shown, the waste solution treatment apparatus 10 according to the present invention is located in the waste solution storage tank 1 in which the waste solution used for the resin coating of the plating process is contained, and the waste solution treatment means configured to remove water from the waste solution. 20, the air supply means 30 connected to the waste solution processing means 20 to supply air to the waste solution processing means 20, and the waste water so that the water removed by the waste solution processing means 20 is discharged. It comprises a water discharge means 40 connected to the solution treatment means 20.

따라서, 폐용액 저장탱크(1)에 담겨진 폐용액은 폐용액 저장탱크(1) 내에 위치한 폐용액 처리수단(20)과 이에 연결된 공기 공급수단(30)의 작용으로 그 안에 함유된 물이 제거되어 부피가 감소하게 되고, 제거된 물은 폐용액 처리수단(20)과 연결된 물 배출수단(40)을 통하여 수처리설비(도시되지 않음)로 보내어 진다. Therefore, the waste solution contained in the waste solution storage tank (1) is removed by the action of the waste solution processing means 20 and the air supply means 30 connected thereto in the waste solution storage tank (1) The volume is reduced, and the removed water is sent to a water treatment facility (not shown) through the water discharge means 40 connected to the waste solution treatment means 20.

폐용액 저장탱크(1)에 담겨진 폐용액의 부피가 감소하게 되므로, 폐용액을 진공펌프 등에 연결된 진공흡입관(4)을 통하여 폐용액 저장탱크(1)외부로 빼내어서 폐기처리하는 폐용액 폐기처리의 주기가 길어지게 된다. Since the volume of the waste solution contained in the waste solution storage tank (1) is reduced, the waste solution is disposed of by discharging the waste solution outside the waste solution storage tank (1) through a vacuum suction pipe (4) connected to a vacuum pump or the like for disposal. The cycle of becomes longer.

즉, 종래에 폐용액 저장탱크(1)에 저장된 폐용액에 물이 함유되어 있어서 수시로 행하던 폐용액 폐기처리를 수시로 해주지 않아도 된다. That is, since the waste solution stored in the waste solution storage tank 1 conventionally contains water, it is not necessary to frequently perform the waste solution disposal process which is frequently performed.

폐용액 처리수단(20)은 도2와 도3에 도시된 바와 같이, 물이 유입되고 공기가 배출되도록 다수의 유동구멍(26)이 형성되며 폐용액 저장탱크(1) 내에 이동가능하며 밀봉되게 위치한 제1처리하우징(21)과, 물이 유입되고 공기가 배출되도록 다수의 유동구멍(26)이 형성되며 제1처리하우징(21)과 연결관(23)에 의해서 연결된 제2처리하우징(22) 및, 제2처리하우징(22)에 연결구(24)에 의해서 연결되어 제1처리하우징(21)과 제2처리하우징(22)을 폐용액 저장탱크(1) 내에서 왕복이동시키는 실린더(25)를 포함한다. 2 and 3, the waste solution processing means 20 is formed with a plurality of flow holes 26 so that water is introduced and air is discharged and is movable and sealed in the waste solution storage tank 1. The first processing housing 21 located therein, and a plurality of flow holes 26 are formed so that water is introduced and air is discharged, and the second processing housing 22 connected by the first processing housing 21 and the connection pipe 23. And a cylinder 25 connected to the second processing housing 22 by a connector 24 for reciprocating the first processing housing 21 and the second processing housing 22 in the waste solution storage tank 1. ).

또한, 유동구멍(26)에는 다수의 매쉬가 형성된 매쉬부재(27)가 구비되어 있으며, 제1처리하우징(21)의 하단 외주에는 밀봉부재(28)가 구비되어 있다. In addition, the flow hole 26 is provided with a mesh member 27 having a plurality of meshes, and a sealing member 28 is provided at the outer periphery of the lower end of the first treatment housing 21.

유동구멍(26)에 메쉬부재(27)가 구비되어 있기 때문에, 메쉬부재(27)를 통하여 공기가 제1처리하우징(21)으로부터 폐용액 저장탱크(1) 내로 유입될 수 있고, 폐용액 저장탱크(1)에 저장된 폐용액에 함유된 물이 매쉬부재(27)를 통하여 제1처리하우징(21) 내로 유입될 수 있게 된다. Since the mesh member 27 is provided in the flow hole 26, air may flow from the first treatment housing 21 into the waste solution storage tank 1 through the mesh member 27, and the waste solution may be stored. Water contained in the waste solution stored in the tank 1 may be introduced into the first treatment housing 21 through the mesh member 27.

또한, 겔형태로 고형화된 폐용액은 메쉬부재(27)를 통과하여 제1처리하우징(21) 내로 유입되지 않게 된다. In addition, the waste solution solidified in a gel form is prevented from flowing into the first treatment housing 21 through the mesh member 27.

제1처리하우징(21)에는 후술할 바와 같이 공기가 분사되는 다수의 공기 분사노즐(35)이 연결된 공기 이동관(34)이 그 내부에 위치되어 있다.  As described below, the first treatment housing 21 has an air moving tube 34 connected to a plurality of air injection nozzles 35 through which air is injected.

도4a에서와 같이 다수의 공기 분사노즐(35)을 통해서 공기가 분사되면, 분사된 공기는 유동구멍(26)을 통해서 폐용액 저장탱크(1)에 담겨진 폐용액으로 유입되게 된다. When air is injected through the plurality of air injection nozzles 35 as shown in FIG. 4A, the injected air is introduced into the waste solution contained in the waste solution storage tank 1 through the flow hole 26.

따라서, 폐용액에 버블링을 발생시킨다. Thus, bubbling occurs in the waste solution.

이때 유동구멍(26)을 통과하는 공기는 겔형태로 고형화된 폐용액이 유동구멍(26)에 구비된 메쉬부재(27)에 엉긴 것을 매쉬부재(27)로부터 분리시켜준다. At this time, the air passing through the flow hole 26 separates the waste solution solidified in a gel form from the mesh member 27 which is entangled in the mesh member 27 provided in the flow hole 26.

따라서, 도4c에 도시된 바와 같이 폐용액에 함유된 물이 유동구멍(26)의 메쉬부재(27)를 통하여 제1처리하우징(21)으로 유입되는 것을 원활하게 해준다. Therefore, as illustrated in FIG. 4C, water contained in the waste solution is smoothly introduced into the first treatment housing 21 through the mesh member 27 of the flow hole 26.

제2처리하우징(22)도 제1처리하우징(21)과 같이 메쉬부재(27)가 구비된 유동구멍(26)이 형성되어 있어서, 제1처리하우징(21)에서와 같이 유동구멍(26)의 메쉬부재(27)를 통해서 공기가 폐용액 저장탱크(1) 내에 저장된 폐용액으로 유입되고, 폐용액에 함유된 물이 유동구멍(26)의 메쉬부재(27)를 통해서 제2처리하우징(22) 내로 유입되도록 한다. Like the first treatment housing 21, the second treatment housing 22 also has a flow hole 26 provided with a mesh member 27, so that the flow hole 26 is formed as in the first treatment housing 21. Air flows into the waste solution stored in the waste solution storage tank 1 through the mesh member 27 of the second solution housing, and the water contained in the waste solution passes through the mesh member 27 of the flow hole 26. 22) Let it flow into.

제2처리하우징(22)은 전술된 바와 같이 연결구(24)를 통하여 실린더(25)와 연결되어 있다. The second processing housing 22 is connected to the cylinder 25 through the connector 24 as described above.

따라서, 도4b에 도시된 바와 같이 실린더(25)를 작동하면, 이에 연결된 제2처리하우징(22)과 제1처리하우징(21)이 왕복운동하게 된다.Accordingly, when the cylinder 25 is operated as shown in FIG. 4B, the second processing housing 22 and the first processing housing 21 connected thereto are reciprocated.

또한, 제1처리하우징(21)의 하단 외주에는 밀봉부재(28)가 구비되어 있다. In addition, a sealing member 28 is provided on the outer circumference of the lower end of the first processing housing 21.

이에 의하여, 폐용액 저장탱크(1)에 저장된 폐용액은 교반되면서 폐용액에 함유된 물이 제거되도록 짜지게 된다. As a result, the waste solution stored in the waste solution storage tank 1 is squeezed to remove water contained in the waste solution while being stirred.

상기와 같은 왕복운동으로 폐용액에 함유된 물이 폐용액으로부터 제거되는 것이 더욱 원활하게 된다. By the reciprocating motion as described above, the water contained in the waste solution is more smoothly removed from the waste solution.

본 실시예에서 제1처리하우징(21)의 형상은 원추형으로 되어 있으나, 이에 한정되지 않고 폐용액 저장탱크(1) 내에 이동가능하며 밀봉되게 위치될 수 있는 형상이라면 어떠한 것이라도 가능하다. In the present embodiment, the shape of the first treatment housing 21 is conical, but is not limited thereto, and may be any shape as long as it is movable and sealed in the waste solution storage tank 1.

공기 공급수단(30)은 도2에 도시된 바와 같이 공기 공급원(32)에 연결되며 공급밸브(33)가 구비된 공기 공급관(31)과, 공기 공급관(31)에 연결되고 제1처리하우징(21) 내에 위치하는 공기 이동관(34) 및, 공기 이동관(34)에 연결되어 상기 제1처리하우징(21) 내에 공기를 분사하는 다수의 공기 분사노즐(35)을 포함한다. As shown in FIG. 2, the air supply means 30 is connected to an air supply source 32 and is provided with a supply valve 33, and is connected to an air supply pipe 31 and a first treatment housing ( 21 and an air moving nozzle 34 connected to the air moving pipe 34 to inject air into the first processing housing 21.

송풍기나 압축기 등의 공기 공급원(32)으로부터 공급된 공기는 공급밸브(33)를 지나 공기 공급관(31)을 유동하게 되고 공기 공급관(31)에 연결된 공기 이동관(34)에 유입되게 된다. Air supplied from the air supply source 32 such as a blower or a compressor flows through the air supply pipe 31 through the supply valve 33 and flows into the air moving pipe 34 connected to the air supply pipe 31.

이러한 작용에 의해서 폐용액 저장탱크(1) 내에 저장된 폐용액은 교반되면서 폐용액에 함유된 물이 제거될 수 있도록 짜지게 된다. By this action, the waste solution stored in the waste solution storage tank 1 is squeezed so that the water contained in the waste solution can be removed while being stirred.

폐용액으로부터 제거된 물은 도4의 (c)에 도시된 바와 같이 제1처리하우징(21)과 제2처리하우징(22) 내로 유입되게 된다. Water removed from the waste solution is introduced into the first treatment housing 21 and the second treatment housing 22 as shown in FIG.

제1처리하우징(21)과 제2처리하우징(22) 내로 유입된 물은 제1처리하우징(21)에 연결된 물배출관(41)으로 모아지게 되고, 배출밸브(42)의 작동으로 배출밸브(42)에 연결된 물 처리관(도시되지 않음)을 통해 수처리설비(도시되지 않음)로 이동하여 처리된다. Water introduced into the first treatment housing 21 and the second treatment housing 22 is collected by the water discharge pipe 41 connected to the first treatment housing 21, and the discharge valve 42 is operated by the operation of the discharge valve 42. 42 is transferred to a water treatment facility (not shown) and treated through a water treatment pipe (not shown) connected to 42).
