압축회전식 고율 농축기 및 농축방법{Compression rotary high-concentration concentrator and concentration method}[0002] Compression rotary high-concentration concentrator and concentration method [0003]

본 발명은 압축회전식 고율 농축기 및 농축방법에 관한 것으로, 더욱 상세하게는 하, 폐수처리장에서 발생하는 슬러지, 음식물폐액, 가축분뇨 등을 농축할 때 미세공에 의한 고형물과 수분을 분리하여 농축효율 및 농축여액 내 고형물의 회수율을 증가시킬 수 있도록 한 압축회전식 고율 농축기 및 농축방법에 관한 것이다. The present invention relates to a compression rotary high-concentration concentrator and a concentrating method, and more particularly, to a method and apparatus for concentrating sludge, food waste, livestock manure, etc. generated in a wastewater treatment plant by separating solids and moisture from micro- Which is capable of increasing the recovery rate of solids in the concentrated filtrate, and a concentrating method.

일반적으로 오수나 폐수는 다량의 수분과 고형물이 혼합되어 있는 상태이므로 이의 정화를 위해서는 응집제를 투입하여 고형물을 응집시킨 후 응집된 고형물과 수분을 분리하는 과정을 거쳐서 처리를 하게 된다.Generally, the wastewater and wastewater are mixed with a large amount of water and solids. Therefore, in order to purify the wastewater, the coagulant is put in to flocculate the solids, and then the flocculent solids and water are separated from each other.

고형물과 수분의 분리방법으로는, 이송되는 필터나 회전하는 스크류에 의해 슬러지를 가압하여 수분을 분리하는 방법이나 회전하는 스크린 드럼의 원심력에 의해 수분을 분리하는 방법이 주로 이용되고 있다.As a method for separating solid matter and water, a method of separating water by pressurizing sludge by a conveyed filter or a rotating screw or a method of separating water by centrifugal force of a rotating screen drum is mainly used.

그러나 이러한 방법을 이용하는 경우, 필터, 스크류, 스크린 드럼 등의 구동을 위해 장치가 복잡하게 되고, 다량의 수분이 함유되어 있는 경우에는 농축효과가 떨어지는 등의 문제점이 있다.However, when such a method is used, the apparatus becomes complicated for driving filters, screws, screen drums, and the like, and when a large amount of water is contained, there is a problem that the concentration effect is lowered.

이러한 문제점을 해결하기 위해 근래에 중력식 농축기가 다수 개발되어 사용되고 있으며, 이러한 예로 한국 등록실용신안공보 등록번호 제20-0385230호(2005.5.25.공고)가 있다. In order to solve these problems, many gravity type concentrators have been developed and used. For example, Korean Registered Utility Model Registration No. 20-0385230 (2005.5.25.

그러나 상기와 같은 종래기술도 슬러지의 충분한 농축이 이루어지지 않고, 사용 중에 고장이 빈번히 발생하는 문제점이 있다.However, the above-described conventional techniques also fail to sufficiently concentrate the sludge, resulting in frequent breakdown during use.

특히, 여과 통체의 운전 중 흔들림, 변형 및 파손의 발생 가능성이 높고 이에 대한 보수를 위한 작업이 어렵고 비용이 많이 소요되는 문제점이 있다.In particular, there is a high possibility that shaking, deformation, and breakage occur during operation of the filtration tube, and it is difficult to perform the repair work and the cost is high.

상기와 같은 종래 기술의 문제점을 해결하기 위한 선행기술로 한국 등록특허공보 제10-1307158호(2013.09.11. 공고) "저동력 드럼식 원심 농축기"는 외부 케이스, 중공 원통형으로 이루어지고, 슬러지 중의 수분이 통과할 수 있도록 다수의 구멍이 형성되는 한 쌍의 스크린 드럼, 각각의 스크린 드럼의 양단에 각각 결합되고, 내부에 중공부가 구비되는 링 형태로 이루어지는 양단 지지용 부재, 각각의 스크린 드럼의 중앙에 서로 이격되어 결합되고, 내부에 중공부가 구비되는 링 형태로 이루어지는 한 쌍의 중간 지지용 부재, 상기 한 쌍의 중간 지지용 부재 사이에 위치하는 링 기어, 각각의 스크린 드럼 하측에 스크린 드럼과 평행하게 설치되되, 양단이 외부 케이스 양측벽에 베어링을 통해 회전가능하게 지지되는 구동 지지축 및 아이들 지지축, 상기 구동 지지축 및 아이들 지지축에 원통형으로 지지축과 동심을 이루도록 설치되되, 상기 양단 지지용 부재 및 중간 지지용 부재와 접하여 스크린 드럼을 지지하는 복수의 지지 롤러 및 상기 구동 지지축에 설치되고, 상기 링 기어와 결합하는 구동 기어를 포함하여 구성되는 것을 특징으로 한다. As a prior art for solving the problems of the prior art as described above, Korean Patent Registration No. 10-1307158 (Announcement of Sep. 11, 2013) "Low Power Drum Centrifugal Concentrator" is composed of an outer case and a hollow cylinder type, A pair of screen drums having a plurality of holes formed therethrough so as to allow the screen drums to pass therethrough, both end supporting members each of which is connected to both ends of each screen drum and has a ring shape in which a hollow portion is provided, A ring gear disposed between the pair of intermediate supporting members, a ring gear disposed between the pair of intermediate supporting members, and a ring gear disposed between the pair of intermediate supporting members in parallel with the screen drum A drive support shaft and an idle support shaft both ends of which are rotatably supported by bearings on both side walls of the outer case, A plurality of support rollers provided on the shaft and the idle support shaft so as to be concentric with the support shaft in a cylindrical shape and supporting the screen drum in contact with the both end support members and the intermediate support members, And a driving gear coupled with the driving gear.

상기와 같이 구성되는 선행기술은 한 쌍의 드럼의 회전에 의해 슬러지에 포함된 수분만을 제거하고, 수분에 포함된 슬러지를 제거하지 못하는 문제점이 있었다. In the prior art as described above, there is a problem that only the moisture contained in the sludge is removed by the rotation of the pair of drums, and the sludge contained in the moisture can not be removed.

또한, 수분에 포함된 슬러지를 재처리하기 위한 재처리장치가 요구되고, 이러한 재처리과정에 의해 처리 비용이 상승되는 문제점이 있었다. Also, there is a need for a reprocessing apparatus for reprocessing the sludge contained in water, and there is a problem that the processing cost is increased by such a reprocessing process.

A cleaning nozzle 230 is installed on one side of the plurality of first concentration drums 210 so that the wedge wire or pores are blocked by the concentrated solid material or the sludge after the coagulation treatment is completed.

상기 여액배출조(300)는 제2농축드럼(310)과, 제2드럼구동모터(미도시)와, 복수의 전동밸브(340a, 340b)를 포함한다. The filtrate discharge vessel 300 includes a second condensing drum 310, a second drum driving motor (not shown), and a plurality of electrically operated valves 340a and 340b.

The second concentration drum 310 is rotatably installed in the filtrate discharge tank 300 so that the sludge included in the concentrated filtrate supplied from the concentration tank 200 is concentrated and remains in the second order.

상기 제2드럼구동모터(미도시)는 상기 제1농축드럼(210)의 일측에 설치된 것과 동일하게 제2농축드럼(310)이 회전하면서 농축여액에 포함된 슬러지를 2차로 농축할 수 있도록 여액배출조(300) 외부에서 설치되어 제2농축드럼(310)과 연결된다.

상기와 같이 구성된 본 발명에 의한 압축회전식 고율 농축기의 작용을 설명하면서 압축회전식 고율 농축방법을 함께 설명한다. The operation of the compression rotary high-concentration concentrator according to the present invention constituted as described above will be described and a compression rotary high-concentration concentration method will be described together.

도 5는 본 발명에 의한 압축회전식 고율 농축기에 의한 농축방법을 단계적으로 나타낸 순서도이다.FIG. 5 is a flowchart showing a step of concentrating by a compression rotary high-concentration concentrator according to the present invention.

도 5를 참조하면, 본 발명에 의한 압축회전식 고율 농축방법은 크게 응집단계(S10)와, 농축단계(S20)와, 압착단계(S30)와 자동세정 및 고형물 분리단계(S40)로 이루어진다. Referring to FIG. 5, the compression rotary high-concentration method according to the present invention comprises a coagulation step (S10), a concentration step (S20), a compression step (S30), an automatic cleaning and a solids separation step (S40).

상기 응집단계(S10)는 하, 폐수처리장에서 발생되는 저농도의 슬러지가 응집교반조(100)로 유입되고, 응집교반조(100)로 유입된 저농도의 슬러지에 응집제를 투여하며, 응집제가 투여된 저농도의 슬러지를 교반모터(110)와 교반기(120)에 의해 응집이 이루어진다. In the flocculating step (S10), the low concentration sludge generated in the wastewater treatment plant flows into the flocculation tank 100, the flocculant is injected into the low concentration sludge introduced into the flocculation tank 100, Agitation of the low concentration sludge is carried out by the stirring motor 110 and the stirrer 120.

상기 농축단계(S20)와 압착단계(S30)는 상기 응집교반조(100)에서 응집액이송부(130)를 통해 응집된 슬러지가 농축조(200)로 응집액이송부(130)를 통해 이송되고, 농축조(200)로 이송되는 응집된 슬러지는 복수의 제1농축드럼(210)의 외측으로 유입되며, 유입되는 응집된 슬러지는 복수의 제1농축드럼(210)이 서로 반대방향으로 회전하면서 유입되는 응축된 슬러지를 압착하여 응축된 슬러지를 농축한다. In the concentration step S20 and the pressing step S30, sludge agglomerated in the agglomeration liquid transfer unit 130 in the agglomeration and agitation tank 100 is transferred to the concentration tank 200 through the agglomeration liquid transfer unit 130 The agglomerated sludge conveyed to the thickening tank 200 flows into the outside of the plurality of first concentration drums 210. The agglomerated sludge that is introduced flows through the plurality of first concentration drums 210 in opposite directions, To condense the condensed sludge and concentrate the condensed sludge.

상기 복수의 제1농축드럼(210)에 의해 압착이 이루어지는 응축된 슬러지는 농축고형물과 농축여액으로 분리된다. The condensed sludge, which is squeezed by the plurality of first condensing drums (210), is separated into a concentrated solid and a concentrated filtrate.

상기 응축된 슬러지를 농축고형물과 농축여액으로 분리할 때 복수의 제1농축드럼(210) 거리는 1mm에서 10mm 범위로 조절이 가능하므로 유입되는 슬러지의 응축된 상태에 따라 작업자에 의해 간격이 조절되면서 압착이 이루어진다.When the condensed sludge is separated into a concentrated solid and a concentrated filtrate, the distances of the plurality of first condensing drums 210 can be adjusted within the range of 1 mm to 10 mm. Therefore, the interval is adjusted by the operator depending on the condensed state of the sludge introduced, .

상기 복수의 제1농축드럼(210)에 형성한 웨지와이어 또는 타공은 100~500㎛(Φ)의 크기로 이루어져 있기 때문에 농축고형물은 제1농축드럼(210)의 내측에 위치하고, 농축여액은 여액집수부(250)를 통해 여액배출조(300)로 유입되도록 한다. Since the wedge wire or pore formed in the plurality of first condensing drums 210 has a size of 100 to 500 μm (Φ), the condensed solid is located inside the first condensing drum 210, And flows into the filtrate discharging tank 300 through the collecting part 250.

그리고 상기 농축단계와 압착단계에서 1차로 모여진 농축고형물은 농축조의 하부에 형성한 호퍼(240)를 통해 선택적으로 배출할 수 있다. The concentrated solids collected in the concentrating step and the pressing step can be selectively discharged through the hopper 240 formed in the lower part of the concentrating tank.

상기 자동세정 및 고형물 분리단계(S40)는 상기 여액집수부(250)를 통해 유입되는 농축여액은 제2농축드럼(310)의 내부로 공급되고, 제2농축드럼(310)으로 유입된 농축여액이 미세공을 통과하면서 제2농축드럼(310) 내에 고형물이 축척되도록 하여 농축여액에 포함된 잔여 슬러지를 제거할 수 있도록 한다.In the automatic cleaning and solids separation step S40, the concentrated filtrate introduced through the filtrate collection section 250 is supplied to the interior of the second concentration drum 310, and the concentrated filtrate flowing into the second concentration drum 310 So that the solid matter is accumulated in the second concentration drum 310 while passing through the fine pores so that the residual sludge contained in the concentrated filtrate can be removed.

그리고 상기 제2농축드럼(310)의 미세공이 고형물의 축척에 의해 막히므로 농축여액의 수위가 높아지면, 이를 여액배출조(300)에 내부에 설치한 수위측정계(330)에서 감지하고, 수위측정계(330)에서 인가되는 신호에 의해 복수의 전동밸브(340a, 340b)가 열리거나 닫혀 외부로부터 농축여액이 여액배출조(300) 내부로 유입되도록 한다.Since the fine pores of the second condensing drum 310 are clogged by the scale of the solids, if the level of the concentrated filtrate becomes high, it is sensed by a water level meter 330 installed in the filtrate discharge tank 300, The plurality of electrically operated valves 340a and 340b are opened or closed by a signal applied from the sensor 330 to allow the concentrated filtrate to be introduced into the filtrate tank 300 from the outside.

상기 여액배출조(300)로 유입된 농축여액에 의해 제2농축드럼(310)을 통과하면서 기존에 고형물에 의해 막혀있던 제2농축드럼(310)의 미세공을 세정한다. The microfluid of the second condensing drum 310, which has been blocked by the solid substance, is cleaned while passing through the second condensing drum 310 by the concentrated filtrate flowing into the filtrate discharging tank 300.

이때 여액은 여액/고형물배출구(350)를 통해 배출되고, 최종적으로 여액배출조(300)에서 잔존하는 고형물은 고형물배출구(360)를 통해 처리된다.At this time, the filtrate is discharged through the filtrate / solids discharge port 350, and finally the solids remaining in the filtrate discharge tank 300 are processed through the solids discharge port 360.

상기의 응집단계(S10)와, 농축단계(S20)와, 압착단계(S40)와 자동세정 및 고형물 분리단계(S50)가 반복적으로 수행되는데, 이는 순환펌프(400)의 구동에 의해 순환이 이루어져 여액 내 잔존하는 고형물이 제거되고. 그로 인하여 여액의 수질을 향상시키는 이점이 있다. The flocculation step (S10), the concentration step (S20), the compression step (S40), the automatic washing step and the solids separation step (S50) are repeatedly carried out by circulation by the driving of the circulation pump The remaining solids in the filtrate are removed. This has the advantage of improving the quality of the filtrate.

상기에서 설명한 바와 같이 하, 폐수처리장에서 발생하는 슬러지, 음식물폐액, 가축분뇨 등을 농축할 때 미세공에 의한 고형물과 수분을 분리하여 농축효율 및 농축여액 내 고형물의 회수율을 증가되는 것은 물론 반복적인 운전을 통해 최종 여액의 수질이 향상되어 정화처리가 용이한 이점이 있다. As described above, when concentrating sludge, food waste liquid, livestock manure and the like generated in a wastewater treatment plant, it is possible to separate the solids and water from the micropores to increase the concentration efficiency and the recovery rate of the solids in the concentrated filtrate, There is an advantage that the quality of the final filtrate is improved through operation to facilitate the purification treatment.

또한, 본 발명은 복수의 제1농축드럼(210)을 통해 응집된 슬러지에서 농축고형물과 농축여액을 분리하고, 농축고형물은 외부로 배출하며, 농축여액은 여액배출조에서 농축여액에 포함된 슬러지를 제2농축드럼(310)을 통해 2차로 분리하므로 최종 여액의 수질이 향상되어 여액의 처리가 용이한 이점이 있다. In addition, the present invention separates the concentrated solids and the concentrated filtrate from the sludge agglomerated through the plurality of first concentration drums 210, discharges the concentrated solids to the outside, and the concentrated filtrate is discharged from the sludge contained in the concentrated filtrate Through the second condensing drum 310, thereby improving the quality of the final filtrate and facilitating the treatment of the filtrate.
