Description

폐수 방류유량 측정장치{Discharge flow measuring device for waste water}Discharge flow measuring device for waste water

본 발명은 폐수 방류유량 측정장치에 관한 것으로 특히 별도의 토목 공사가 필요없이 소량의 폐수를 방류하는 공장등에 적합한 폐수 방류유량 측정장치에 관한 것이다.The present invention relates to a wastewater discharge flow rate measurement device, and more particularly, to a wastewater discharge flow rate measurement device suitable for a factory that discharges a small amount of wastewater without the need for separate civil works.

소규모 공장을 포함한 공장들에서 방류되는 폐수는 그 방류 유량이 적고 비만관으로 흐르기 때문에 파샬 플룸(parshall flume)을 기반으로 설치되는 유량 측정 장치가 사용되고 있다. 도 1에는 종래의 폐수 방류유량 측정장치에 사용되는 퍄샬 플룸의 구조를 사시도로써 나타내었다. 도 1을 참조하면 파샬 플룸(parshall flume)은 유량계의 일종으로 개수로의 도중에 잘록한 부분을 설치하여 단면적은 줄이고 수위를 높이며 흐름의 상태를 보통의 흐름에서 빠른 흐름으로 변화시키면, 그 상류측의 수위가 유량과 일정한 관계를 갖는 것을 이용하여 수위 변화를 플로트식 수위계나 초음파 수위계 등으로 검출하여 유량을 측정한다. 이와 같은 파샬 플룸 방식의 유량계는 손실 수두가 적고, 수중에 고형물의 퇴적이 잘 생기지 않기 때문에 정밀도의 저하가 없으며, 측정 범위가 비교적 넓다는 등의 특성이 있어서 폐수 유량 측정에 사용되고 있다.Since wastewater discharged from factories, including small factories, has a small discharge flow and flows through the fat pipe, a flow measurement device installed based on a parshall flume is used. 1 is a perspective view showing the structure of a primary plume used in a conventional wastewater discharge flow measurement device. Referring to FIG. 1 , a parshall flume is a type of flow meter, and by installing a constricted part in the middle of an open channel to reduce the cross-sectional area, increase the water level, and change the state of the flow from a normal flow to a fast flow, the water level on the upstream side The flow rate is measured by detecting the change in the water level with a float type water level meter or ultrasonic level meter, etc. Such a partial plume type flowmeter has characteristics such as a small loss head, no decrease in precision because solids are not easily deposited in water, and a relatively wide measurement range, so it is used for wastewater flow measurement.

하지만, 파샬 플룸 방식은 설치를 위한 토목공사가 필요하기 때문에 실제 현장에서 방류 유량을 측정하기 위하여 요구되는 설치 비용이 높을 뿐만 아니라 토목 공사의 불확실로 인하여 정확한 경사로 설치하기가 어렵고 수위 높이에 따라 유속이 변하기 때문에 정확한 유량 측정이 어렵다는 문제점이 있다. 또한, 소규모 폐수방류 공장의 경우는 매우 낮은 수위를 유지하기 때문에 측정이 제대로 되지 않는 경우도 있다.However, since the partial plume method requires civil work for installation, the installation cost required to measure the discharge flow rate at the actual site is high, and it is difficult to install it on an accurate slope due to the uncertainty of civil works, and the flow rate varies depending on the water level. There is a problem in that it is difficult to accurately measure the flow rate because it changes. In addition, in the case of a small wastewater discharge plant, the measurement may not be performed properly because the water level is kept very low.

도 2에는 종래의 폐수 방류유량 측정장치에 사용되는 비만관 초음파 유량측정 장치의 구조를 단면도로써 나타내었다. 도 2를 참조하면, 비만관 폐수를 측정하기 위한 종래의 다른 유량 측정 장치는 파이프 내부에 여러 경로로 초음파 트랜스듀서를 설치하며 유속을 측정하고, 수위계로 면적을 계산한다. 하지만, 이러한 유량 측정 장치는 가격이 고가이고 파이프가 원형인 경우만 설치가 가능하며 1 경로 이하의 수위에서는 측정이 불가능하다는 문제점이 있다.2 is a cross-sectional view showing the structure of an ultrasonic flow rate measuring device for obesity pipe used in a conventional wastewater discharge flow measuring device. Referring to FIG. 2 , another conventional flow measurement device for measuring the wastewater from the obese pipe installs an ultrasonic transducer in several paths inside the pipe, measures the flow rate, and calculates the area with a water level meter. However, such a flow measurement device has a problem in that it is expensive and can be installed only when the pipe is circular, and cannot be measured at a water level of one path or less.

본 발명은 상기한 문제점들을 해결하기 위하여 개발된 것으로 본 발명이 이루고자 하는 기술적 과제는 별도의 토목 공사가 필요없이도 소량의 폐수를 방류하는 공장등에 적용하기가 용이한 폐수 방류유량 측정장치를 제공하는 것이다.The present invention was developed to solve the above problems, and the technical problem to be achieved by the present invention is to provide a wastewater discharge flow rate measuring device that is easy to apply to factories that discharge a small amount of wastewater without the need for separate civil works. .

도 3에는 본 발명의 바람직한 일 실시예에 따른 폐수 방류유량 측정장치의 구조를 부분 절개 사시도로써 나타내었다. 도 3을 참조하면 본 발명에 따른 폐수 방류유량 측정장치(3)는 폐수를 방류하기 전에 그 폐수가 저장되는 저류조(R)에 투입되는 것으로 부력을 가지는 플로팅 부재(30)와, 상기 플로팅 부재(30)의 내부에 저류조(R)의 바닥으로부터 표면까지의 수위를 측정하는 수위 측정부(32)를 구비한다.3 is a partially cut-away perspective view showing the structure of a wastewater discharge flow rate measuring apparatus according to an exemplary embodiment of the present invention.

도 4에는 본 발명에 따른 폐수 방류유량 측정장치(3)에 구비되는 수위 측정부와 배출 펌프의 동작을 설명하기 위한 흐름도를 나타내었다. 도 4를 참조하면, 저류조(R)로 폐수가 유입(단계 S400)되어 수위가 상승하다가 수위 측정부(32)에 의하여 고수위가 감지(단계 S402)되면, 제어부(미도시)는 배출 펌프(33)를 가동하도록 지시한다. 배출 펌프(33)가 가동(단계 S404)되어 배출이 이루어지면 유량 측정부(36)은 방류 유량을 측정 및 적산한다(단계 S405). 배출 펌프(33)의 가동에 의하여 폐수가 배출됨으로써 수위가 낮아져 수위 측정부(32)에 의하여 저수위가 감지(단계 S406)되면 제어부(미도시)는 배출 펌프(33)의 가동을 중지하도록 지시한다(단계 S408).4 is a flowchart for explaining the operation of the water level measurement unit and the discharge pump provided in the wastewater discharge flow rate measuring device 3 according to the present invention. Referring to FIG. 4 , when wastewater flows into the storage tank R (step S400) and the water level rises, and the high level is detected by the water level measurement unit 32 (step S402), the controller (not shown) controls the discharge pump 33 ) to run. When the discharge pump 33 is operated (step S404) and discharge is made, the flow rate measurement unit 36 measures and integrates the discharge flow rate (step S405). When the water level is lowered by discharging wastewater by the operation of the discharge pump 33 and the low water level is detected by the water level measuring unit 32 (step S406), the control unit (not shown) instructs to stop the operation of the discharge pump 33 (Step S408).

Now, the integration and communication processing unit 362 integrates the measured flow rate from the high water level to the low water level and when the wastewater discharge data is determined, it converts the wastewater discharge amount data appropriately to the communication protocol and transmits the wastewater discharge amount data to the monitoring institution through the communication antenna 39 do (step S410).

도 5에는 본 발명에 따른 폐수 방류유량 측정장치의 작용 효과를 설명하기 위한 도면을 나타내었다. 도 5를 참조하면, 상기와 같은 본 발명에 따른 폐수 방류 유량 측정 장치에 구비되는 플로팅 부재(30)는 예컨대 내부에 공기층을 구비하여 부력을 가짐으로써 저류조(R)의 물 표면에 부유하게 되고, 플로팅 부재(30) 내부에는 저류조 내의 폐수를 배출하기 위한 배출 펌프(33)가 매립되고 수위 측정부(32)는 바닥에서 표면까지의 수위를 측정하며 미리 설정된 고수위에 도달한 것으로 감지되면 배출 펌프(33)를 가동하고 저류조(33) 내부의 폐수가 배출된다. 유량 측정부(36)는 배출 펌프(33)에 의하여 배출되는 폐수량의 측정을 시작한다.5 is a view for explaining the effect of the wastewater discharge flow measurement device according to the present invention. 5, the floating member 30 provided in the wastewater discharge flow rate measuring device according to the present invention as described above has, for example, an air layer therein to have buoyancy, so that it floats on the surface of the water of the storage tank R, A discharge pump 33 for discharging wastewater in the storage tank is buried inside the floating member 30, and the water level measuring unit 32 measures the water level from the bottom to the surface, and when it is sensed that a preset high level has been reached, the discharge pump ( 33) and the wastewater inside the storage tank 33 is discharged. The flow rate measurement unit 36 starts to measure the amount of wastewater discharged by the discharge pump 33 .

저류조 내부의 폐수가 배출됨으로써 수위가 낮아지면 본 발명에 따른 폐수 방류유량 측정장치는 수위를 따라 아래로 이동하며, 계속해서 저류조 내부의 폐수가 배출됨으로써 미리 설정된 저수위에 도달한 것으로 감지되면 배출 펌프의 가동을 중지한다. When the water level is lowered by discharging the wastewater inside the storage tank, the wastewater discharge flow rate measuring device according to the present invention moves downward along the water level, and when it is detected that the wastewater inside the storage tank has reached a preset low water level by continuously discharging it, the discharge pump stop operation

소량의 폐수를 방류하는 공장등에는 하수 처리 장치를 통과한 후 일반적으로 저류조를 거쳐 방류하게 되는데 도 6에 도시한 바와 같이 본 발명에 따른 폐수 방류유량 측정장치를 저류조의 폐수 표면에 놓고 도 4를 참조하여 설명한 바와 같이 폐수가 유입되어 수위가 미리 설정한 고수위에 도달하면 배출 펌프를 가동하면서 유량을 측정한다. 본 발명에 따른 폐수 방류유량 측정장치는 플로팅 부재에 의하여 수위가 낮아지면 하강하게 되고 미리 설정한 저수위에 도달하면 배출 펌프의 가동을 중지하고 방류 유량을 적산하여 방류량이 결정된다. In factories that discharge a small amount of wastewater, it is generally discharged through a storage tank after passing through a sewage treatment device. As described with reference, when wastewater flows in and the water level reaches a preset high level, the flow rate is measured while operating the discharge pump. In the wastewater discharge flow measurement device according to the present invention, when the water level is lowered by the floating member, the discharge amount is determined by stopping the operation of the discharge pump and accumulating the discharge flow rate when a preset low water level is reached.

상기와 같은 본 발명에 따른 폐수 방류유랑 측정장치는 폐수를 방류하는 통상의 소규모 공장등에서 방류할 폐수를 임시로 저장하는 저류조를 구비하고 있다는 것에 착안하여 이러한 저류조에 본 발명에 따른 폐수 방류유량 측정장치를 저류조에 투입하는 것만으로 폐수 방류유량을 측정하기 위하여 별도의 토목 공사가 필요없고 만관 형태로 유량을 측정하기 때문에 측정 정확도가 매우 높으며 부유식으로 일정 수위까지만 펌핑 작동하기 때문에 바닥의 퇴적물에 의한 영향이 적다는 효과가 있다.The wastewater discharge flow measurement apparatus according to the present invention as described above is based on the fact that it has a storage tank for temporarily storing wastewater to be discharged from a typical small-scale factory that discharges wastewater, and the wastewater discharge flow rate measurement device according to the present invention in such a storage tank In order to measure the wastewater discharge flow rate simply by putting it into the storage tank, there is no need for separate civil works, and the measurement accuracy is very high because the flow rate is measured in the form of a full pipe. This is less effective.
