Description

팜 공정 폐수 고도물 처리장치{Palm Oil Mill Effluent Treatment Equipment}Palm Oil Mill Effluent Treatment Equipment

본 발명은 팜 열매로부터 팜 오일(palm oil)을 채취하는 과정에서 발생하는 공정 폐수를 탈수하여 기존 혐기 처리 시 발생하는 암모니아 개스 및 방류수 수질을 개선하고 슬러지는 퇴비 등으로 이용될 수 있도록 하는 팜 공정 폐수 고도물 처리장치에 관한 발명이다.The present invention is a palm process to improve the ammonia gas and effluent water quality generated during the conventional anaerobic treatment by dehydrating the process wastewater generated in the process of extracting palm oil (palm oil) from palm fruit, so that the sludge can be used as a compost The present invention relates to a wastewater advanced waste treatment apparatus.

주로 열대지방에서 생산되는 팜 열매는 상당량의 오일을 함유하고 있으며 팜 열매로부터 얻어지는 오일 즉 팜유는 각종 식품에 널리 이용되고 있으나,Palm fruit mainly produced in the tropics contains a considerable amount of oil, and oil obtained from palm fruit, or palm oil, is widely used in various foods,

그 수요의 증가로 인하여 오일을 추출하고 난 다음에 발생하는 많은 양의 공정폐수를 효과적으로 처리할 수가 없어서 많은 문제점을 발생시키고 있다.Due to the increased demand, it is not possible to effectively treat a large amount of process wastewater generated after oil extraction, which causes many problems.

오일이 제거된 팜 공정폐수는 미세한 섬유질과 다량의 수분으로 이루어져 있으며 각종 영양소도 충분히 함유하고 있어서 가축의 사료로 매우 적합할 뿐만 아니라 양질의 퇴비로도 손색이 없다.The oil-free palm process wastewater is composed of fine fiber and a large amount of water, and contains various nutrients, so it is not only suitable for feed for livestock but also good for compost.

그러나 이와같은 팜유 정제 공정에서 발생되는 폐수는 그 특성상 다량의 수분(98%)과 미세한 섬유질로 이루어져 있어, 이와 같은 사료나 퇴비로 이용될 수 있을 정도로 처리하는 데에는 상당한 어려움이 있다.However, the wastewater generated in the palm oil refining process is composed of a large amount of water (98%) and fine fibers due to its characteristics, there is a considerable difficulty in treating such that can be used for such feed or compost.

즉 처리장치를 비롯한 제반비용 등 많은 난제 때문에 현재는 대부분 혐기방식의 폐수처리를 하고 있어, 환경오염에 미치는 영양이 지대한 것이다.In other words, due to many difficulties such as treatment equipment and other costs, most anaerobic wastewater treatment is performed, and the nutrition of environmental pollution is enormous.

한편, 종래에도 팜유생산 공정 폐수에 포함된 찌꺼기를 분리 제거하는 장치 즉 탈수장치 및 건조수단이나 방법들이 알려지고 있다.On the other hand, conventionally known devices for separating and removing the residue contained in the waste oil production process waste water, that is, a dehydration device and drying means or methods are known.

종래 알려지고 있는 장치나 방법들은 필터를 이용한 강제 압착방식이나 원심 분리식을 이용하고 있으나 과즙 내 모세관 기공에 있는 포화 수분과 섬유질에 의한 내부저항에 의하여 수분이 충분히 배출되지 못하는 문제점이 있다.Conventionally known devices or methods use a forced compression method or a centrifugal separation using a filter, but there is a problem that the moisture is not sufficiently discharged due to the saturated resistance in the capillary pores in the juice and the internal resistance by the fiber.

이 또한 고분자 응집제인 화학약품을 이용하여 응집력을 높여서 탈수 효과를 기대하는 방법으로 하고 있으나, 이와 같은 방법은 고분자 응집에 따른 처리비용 부담이 크고 화학 약품 처리로 인하여 사료로 이용하기에 부적합한 문제점이 있다.In addition, the dehydration effect is expected by increasing the cohesive force by using a chemical coagulant, but such a method has a problem in that the processing cost burden due to the coagulation of the polymer is high and it is unsuitable for use as a feed due to the chemical treatment. .

따라서 현재는 고분자 응집제를 이용하지 않고 일반적인 탈수 수단으로 함수율을 낮추고자 노력하고 있으나, 사료나 퇴비로 사용될 수 있도록 함수율을 낮추기가 쉽지 않다.Therefore, at present, efforts have been made to lower the moisture content as a general dehydration means without using a polymer flocculant, but it is not easy to lower the moisture content so that it can be used as feed or compost.

특히, 이와 같은 종래 탈수장치들은 함수율이 매우 높고 미세한 섬유질로 이루어진 과즙 상태의 것을 탈수하는데 한계가 있어 매우 어려움이 있다.In particular, such a conventional dehydration device is very difficult because there is a limit to the dehydration of the juice state made of very high moisture content and fine fibers.

본 발명의 배경기술로는 본 출원인이 선 출원한 특허출원 제10-2009-0074170호(팜 슬러지 처리장치)가 있다.Background art of the present invention is a patent application No. 10-2009-0074170 (Palm Sludge Treatment Apparatus) previously filed by the applicant.

상기 외통체(11) 상단에 증기배출구(17)가 형성되며, 외통체(11) 상단에 형성된 증기배출구(17) 및 팜 슬러지배출구(36) 근처의 수분여과망(12) 외주면에 히터(19)가 형성되도록 하였다.A steam outlet 17 is formed at an upper end of the outer cylinder 11, and a heater 19 is formed on the outer circumferential surface of the water filtration network 12 near the steam outlet 17 and the palm sludge outlet 36 formed at the upper end of the outer cylinder 11. Was formed.

상기에 있어, 슬러지 배출수단(30)은, 외통체(11) 상단에 고정되어지되 내측에 슬러지 배출홈을 갖는 고정판(31)과,In the above, the sludge discharge means 30 is fixed to the upper end of the outer cylinder 11, but the fixing plate 31 having a sludge discharge groove on the inside,

이와 같은 구성을 갖는 본 발명을 보다 상세히 설명하면 다음과 같다.Referring to the present invention having such a configuration in more detail as follows.

내측에 스크류(13)가 장착된 수분여과망(12) 하단에는, 팜유 추출 후 공정폐수를 투입하는 투입구(18)가 형성되어 있으며, 공정폐수 투입구(18) 맞은편에는 수분배출구(16)가 형성되어 있다.At the lower end of the water filtration network 12 equipped with a screw 13 inside, an inlet 18 for injecting process wastewater after palm oil extraction is formed, and a water outlet 16 is formed opposite the process wastewater inlet 18. It is.

따라서, 공정폐수 투입구(18)에 투입된 팜 공정폐수는 모터(14) 및 감속기(15)에 의해 구동된 스크류(13)에 의해 압착되면서 외통체(11) 상단 방향으로 이송하게 되고, 이송하면서 1차 중간밸브(37)에 의하여 탈수하고 수분은 수분여과망(12)을 통해 외통체(11)에 하단에 형성된 수분배출구(16)에 의해 외부로 배출되어진다.Therefore, the palm process wastewater injected into the process wastewater inlet 18 is transferred by the screw 13 driven by the motor 14 and the reducer 15 to the upper side of the outer cylinder 11, and is transported. The water is discharged by the intermediate valve 37, and the water is discharged to the outside by the water outlet 16 formed at the lower end of the outer cylinder 11 through the water filtration network 12.

상기에 있어 외통체(11)는 지지대(40)에 의해 경사지게 재치되어 있으므로, 탈수된 수분은 상기 외통체(11)의 경사도를 따라 신속하게 흘러내리게 되어, 탈수율과 탈수 시간을 단축시키게 된다.In the above, since the outer cylinder 11 is inclined by the support 40, the dehydrated water quickly flows down the inclination of the outer cylinder 11, thereby shortening the dehydration rate and the dehydration time.

상기에 있어, 경사도의 경사각은 종래에는 25~35°정도였으나, 본 발명에서는 35~45°정도로 더욱 경사지게 구성토록 함으로서, 보다 신속한 수분 배출이 이루어지도록 하였다.In the above, the inclination angle of the inclination was conventionally about 25 to 35 °, but in the present invention by configuring to be more inclined to about 35 to 45 °, it was made to discharge the water more quickly.

한편, 스크류(13)를 구동시키는 스크류축(13-1)은 슬러지 이동 방향 쪽을 향해 갈수록 그 외경이 점차 커지도록 구성되어 있으므로, 외통체(11) 상단 쪽으로 갈수록 수분여과망(12)과 스크류축(13-1) 사이의 공간은 점차 좁아지게 된다.On the other hand, the screw shaft 13-1 for driving the screw 13 is configured so that the outer diameter gradually increases toward the sludge moving direction, the water filtration network 12 and the screw shaft toward the upper end of the outer cylinder (11) The space between (13-1) becomes gradually narrower.

따라서, 수분여과망(12)의 상단 쪽으로 갈수록 팜 열매에 가해지는 압력이 점차 높아지게 되어 탈수 효율을 크게 높일 수가 있게 되어 중간밸브(37)에서 1차 탈수한다.Therefore, the pressure applied to the palm fruit gradually increases toward the upper end of the water filtration network 12, so that the dewatering efficiency can be greatly increased, and the primary valve is dewatered from the intermediate valve 37.

그리고 중간밸브(37)를 통과한 슬러지는 2차스크류축(13-2) 및 2차수분여과망(12-1) 에 의해 탈수되어 더욱 함수율을 낮춘다.(2단 압축 스크류 탈수방식)And the sludge passed through the intermediate valve 37 is dewatered by the secondary screw shaft 13-2 and the secondary water filtration network 12-1 to further lower the water content. (2-stage compression screw dewatering method)

한편, 상기 스크류(13)의 외주면 단부에는 합성고무와 같은 내마모성 패킹부재(21)를 끼움으로서, 스크류(13)가 직접 수분여과망(12)에 닿지 않도록 하여 수분여과망(13)이 마모되거나 손상되는 것을 방지하였다.On the other hand, by inserting the wear-resistant packing member 21, such as synthetic rubber at the end of the outer peripheral surface of the screw 13, so that the screw 13 does not directly contact the water filtration network 12 is worn or damaged To prevent it.

또한, 수분여과망(12)의 내면과의 밀착도도 높아지게 되어 탈수에 따른 압력을 커지게 함과 동시에 슬러지의 역류도 방지할 수 있어서 탈수 효율 및 슬러지의 이송 속도를 높일 수 있는 효과도 있다.In addition, the degree of close contact with the inner surface of the water filtration network 12 is also increased to increase the pressure due to dehydration, and also prevent backflow of the sludge, thereby increasing the dewatering efficiency and the sludge conveying speed.

한편, 수분여과망(12)의 외주면에는 다수개의 지지부재(20)를 부착하여, 수분 여과망(12)이 터져 나가는 것을 방지하였는 바, 상기 지지부재(20)는 압력이 점점 커지는 수분여과망(12)의 상단 쪽을 향해 갈수록 그 수를 늘리도록 하였다.On the other hand, a plurality of support members 20 are attached to the outer circumferential surface of the water filtration network 12 to prevent the water filtration network 12 from bursting, and the support member 20 has a pressure filtration network 12 in which pressure is gradually increased. Towards the upper end of the number was increased.

한편, 수분여과망(12)의 상단에는 본 발명의 요부 구성이라 할 수 있는 히터(19) 및 증기배출구(17)와 슬러지 자동 배출부재(30)를 형성토록 하였다.On the other hand, the upper end of the water filtering network 12 to form a heater 19 and the steam outlet 17 and the sludge automatic discharge member 30, which can be said to be the main portion of the present invention.

원래, 본 발명의 배경기술이 되는 본 출원인의 선 출원 특허 제10-2009-0074170호(팜 슬러지 처리장치)에도 히터는 장착되어 있다.The heater is also attached to the prior application patent No. 10-2009-0074170 (Palm Sludge Treatment Apparatus), which is the background art of the present invention.

그러나, 선 출원 특허의 경우는 스크류축 내부를 공간부로 형성한 후, 상기 공간부에 히터를 장착하는 구조를 채택함으로써, 그 구성이 복잡하고, 히터의 효율성이 약간 떨어지는 문제점이 있었다.However, in the case of the pre-patent patent, by adopting a structure in which the inside of the screw shaft is formed as a space portion and then attaching the heater to the space portion, the configuration is complicated and the efficiency of the heater is slightly reduced.

그러나, 본 발명은 히터(19)가 수분이 직접 배출되는 수분여과망(12) 외주면에 장착되는 것이므로, 건조 효과를 증대시킬 수 있으며, 또한 히터(19)를 용이하게 장착할 수 있는 잇점도 있다.However, since the heater 19 is mounted on the outer circumferential surface of the water filtration network 12 from which water is directly discharged, the drying effect can be increased, and the heater 19 can be easily mounted.

특히, 외통체(11) 상단 일측에 증기배출구(17)를 형성토록 하여, 슬러지가 보다 용이하게 건조될 수 있도록 하였다.In particular, the steam outlet 17 is formed on one side of the upper end of the outer cylinder 11, so that the sludge can be dried more easily.

즉 히터(19)에 의해 슬러지가 건조되면서 발생되는 증기를 신속하게 배출시키도록 함으로써, 슬러지의 건조 효율을 증대시킨 것이다.In other words, by rapidly discharging the steam generated while the sludge is dried by the heater 19, the drying efficiency of the sludge is increased.

한편, 이렇게 수분이 탈수되고 건조된 슬러지는 스크류(13)의 이송 압력에 의하여, 외통체(11)의 최고상단 까지 이송하게 되고, 이송된 슬러지는 배출수단(30)에 의하여 슬러지배출구(36)를 통하여 배출되어 진다.On the other hand, the water is dewatered and dried sludge is conveyed to the uppermost top of the outer cylinder 11 by the conveying pressure of the screw 13, the conveyed sludge is discharged to the sludge discharge port 36 by the discharge means (30) It is discharged through.

상기에 있어, 슬러지를 자동으로 배출하는 슬러지 배출수단(30)은, 외통체(11) 상단에 고정되어지되 내측에 슬러지 배출홈을 갖는 고정판(31)과, 상기 슬러지 배출홈을 개폐하는 개폐판(32)과, 상기 개폐판(32)을 눌러주는 코일스프링(33)과, 상기 개폐판(32)의 후방에 구성된 지지구(34)와, 상기 지지구(34)와 나사 결합하되 상기 코일스프링(33)을 지지하는 지지캡(35)과, 팜 슬러지가 배출되는 슬러지배출구(36)로 이루어지는 바,In the above, the sludge discharge means 30 for automatically discharging the sludge is fixed to the upper end of the outer cylinder 11, the fixing plate 31 having a sludge discharge groove on the inside, and the opening and closing plate for opening and closing the sludge discharge groove. (32), the coil spring (33) for pressing the opening and closing plate 32, the support member 34 formed in the rear of the opening and closing plate 32, and the screw and the screw coupling with the support 34 but the coil A support cap 35 supporting the spring 33 and a sludge discharge port 36 through which palm sludge is discharged,

이송되는 슬러지의 압력이 커지면, 슬러지가 코일스프링(33)의 힘으로 배출구의 입구를 막고 있는 개폐판(32)을 밀치게 되고, 개폐판(32)이 밀쳐지면 배출구로 향하는 통로가 생기게 되므로 상기 통로를 통하여 슬러지가 빠져 나오면서 슬러지배출구(36)를 통하여 슬러지는 배출되는 것이다.When the pressure of the conveyed sludge increases, the sludge pushes the opening and closing plate 32 blocking the inlet of the outlet by the force of the coil spring 33, and when the opening and closing plate 32 is pushed, a passage to the outlet is created. As the sludge exits through the passage, the sludge is discharged through the sludge discharge port 36.

즉, 슬러지의 압력이 개폐판(32)을 저지하고 있는 코일스프링(33)의 탄성력 보다 작을 때에는 개폐판(32)이 밀쳐지지 아니하나, 슬러지의 압력이 코일스프링(33)의 탄성력 보다 커지면 코일스프링(33)이 오므라들면서 개폐판(32)이 후방으로 밀쳐지게 되어 슬러지배출구(36)로 향하는 통로가 열리게 되는 것이다.That is, when the pressure of the sludge is less than the elastic force of the coil spring 33 that blocks the opening and closing plate 32, the opening and closing plate 32 is not pushed, but when the pressure of the sludge is greater than the elastic force of the coil spring 33, the coil As the spring 33 is retracted, the opening and closing plate 32 is pushed to the rear to open the passage toward the sludge discharge port 36.

한편, 상기 슬러지 개폐판(32)을 받쳐주는 코일스프링(33)의 탄발력의 세기는 슬러지 개폐판(32)의 개폐 여부를 좌우하는 것이므로, 슬러지의 배출속도, 배출량 뿐만 아니라 수분 탈수율 및 탈수 속도까지 조절하게 된다.On the other hand, since the strength of the elastic force of the coil spring 33 supporting the sludge opening and closing plate 32 depends on the opening and closing of the sludge opening and closing plate 32, the sludge discharge rate, discharge rate as well as moisture dehydration rate and dehydration The speed is controlled.

즉 코일스프링(33)의 탄발력이 약하면 개폐판(32)이 빨리 열리게 되어 슬러지의 탈수시간과 배출속도가 빨라지게 되고, 코일스프링의 탄발력이 강하면 개폐판(32)이 늦게 열리게 되므로, 슬러지의 탈수시간과 배출속도가 느려지게 되는 것이다.That is, when the elastic force of the coil spring 33 is weak, the opening and closing plate 32 is opened quickly, so that the dewatering time and the discharge speed of the sludge are faster, and the opening and closing plate 32 is opened late when the coil spring is strong, the sludge Dehydration time and discharge rate will be slowed down.

상기 코일스프링의 탄발력 세기 조절은 코일스프링(33)을 감싸고 있는 지지구(34)와 코일스프링(33)을 후방에서 지지하고 있는 지지캡(35)의 거리 간격 조절로 가능한바, 지지구(34)와 나사(38) 방식으로 연결되어 있는 지지캡(35)을 후방으로 후진시켜 고정시키면 코일스프링의 탄발력이 약해지고, 지지캡(35)을 전방으로 당겨서 고정시키면 코일스프링의 탄발력이 강해지게 된다.The elastic force intensity control of the coil spring is possible by adjusting the distance interval between the support 34 surrounding the coil spring 33 and the support cap 35 supporting the coil spring 33 from the back, the support ( 34) and the support cap 35, which is connected by the screw 38 method, is moved backward to fix the coil spring's elasticity, and when the support cap 35 is pulled forward and fixed, the coil spring's elasticity is strong. You lose.

상기에 있어서, 미 설명부호 60,61은 패킹, 70은 베어링보호캡, 71은 베어링이다.In the above description, reference numeral 60, 61 is a packing, 70 is a bearing protection cap, 71 is a bearing.

한편, 본 발명의 타 실시 예로써, 도4에서 보는 바와 같이, 슬러지배출구(36)의 하단에 송풍팬(50)이 부착된 공기흡입구(51)를 형성하고, 슬러지배출구(36)의 상단에 공기배출구(55)를 형성토록 하되, 슬러지배출구(36) 내측에 진동여과 판(52)을 형성토록 함으로써, 슬러지의 건조 효과를 더욱 높일 수 있도록 하였다.On the other hand, as another embodiment of the present invention, as shown in Figure 4, to form the air intake port 51 with the blowing fan 50 is attached to the lower end of the sludge discharge port 36, the upper end of the sludge discharge port 36 The air outlet 55 is formed, but the vibration filtration plate 52 is formed inside the sludge outlet 36 to further increase the drying effect of the sludge.

상기 진동여과판(52)은 모터(53)에 의해 작동하는 것으로서, 모터(53) 일측에 편심되게 부착된 캠(54)의 떨림에 의하여 진동하게 되고, 상기 진동여과판(52) 위에 떨어지는 슬러지는 진동되면서 매쉬 형태의 진동여과판(52)을 통과하여 하방으로 배출되어 진다.The vibration filtering plate 52 is operated by the motor 53, vibrates by the vibration of the cam 54 attached eccentrically to one side of the motor 53, the sludge vibration falling on the vibration filtering plate 52 While being passed through the mesh filter vibration filter plate 52 is discharged downward.

즉 송풍팬(50)의 작동에 의해 공기흡입구(51)를 통해 흡입된 공기가 하부에서 상부로 진동여과판(52)를 통과하여 공기배출구(55)로 빠져나갈 때, 진동여과판(52) 위로 떨어진 슬러지는 다시 진동되면서 건조되므로 슬러지의 건조 효과를 더욱 증대시킬 수 있게 되는 것이다.That is, when the air sucked through the air suction port 51 by the operation of the blowing fan 50 passes through the vibration filtering plate 52 from the lower part to the upper part and escapes to the air discharge port 55, Since the sludge is dried again while vibrating, it is possible to further increase the drying effect of the sludge.

한편, 이렇게 배출된 슬러지는 건조가 잘되어진 상태이므로 포장이나 운반이 용이하고 상당 시간 동안 보관할 수 있는 이점을 갖게 된다.On the other hand, since the discharged sludge is well dried, it is easy to pack or transport and has the advantage of being stored for a considerable time.

이상과 같이, 본 발명은 팜오일 공정폐수를 압착 스크류 로 수분을 탈수시키고, 히터로 건조시킨 것으로, 종래에는 폐기시켰던 팜오일 공정폐수를 사료나 퇴비 등으로 사용할 수 있어 그 효과가 상당한 것이다.As described above, in the present invention, the palm oil process wastewater is dehydrated with a crimping screw and dried with a heater. The palm oil process wastewater, which has been conventionally disposed, can be used as feed or compost, and the effect is considerable.
