Description
본 고안은 폐수집수정의 슬러지제거를 위한 역세척장치에 관한 것으로, 더욱 상세하게는 폐수열 회수장치로 폐수를 공급하는 폐수집수정의 하측으로 다수개의 주소제변 및 역지변이 장착된 역세장치를 장착함으로써, 폐수집수정 내부에 흡착 또는 적층되어 있는 슬러지들을 역세를 통해 용이하게 제거할 수 있을 뿐만 아니라, 폐수집수정에 장착된 수위감지센서를 통해 슬러지의 자동 세척이 가능하여 폐온수의 유출을 방지할 수 있는 역세척장치에 관한 것이다.The present invention relates to a backwashing device for sludge removal of a wastewater collection well, and more particularly, a backwashing device equipped with a plurality of address changes and reverse grounds is installed below the wastewater collection well for supplying wastewater to the wastewater heat recovery device. Thus, sludge adsorbed or stacked inside the wastewater collection well can be easily removed through backwashing, and the sludge can be automatically washed through the water level sensor mounted on the wastewater collection well to prevent the wastewater from leaking. A backwashing device that can be used.
일반적으로 폐수열 회수장치는 목욕탕, 수영장, 공장 등에서 버려지는 폐수의 열을 회수하여 재활용하는 장치로, 다수개의 필터와 넘침관이 장착된 폐수 집수정으로 오폐수가 유입되고, 유입된 오폐수는 여과과정을 거친 후 폐수열회수기로 유입되어 열교환되는데, 열교환된 오폐수는 폐수 배출관을 통해 배출되고, 예열수는 목욕탕, 수영장, 공장 등으로 공급되어 지는 것이다.In general, wastewater heat recovery system is a device that recovers and recycles waste water that is discarded in a bathroom, swimming pool, or factory. Wastewater is introduced into a wastewater collection well equipped with a plurality of filters and overflow pipes. After coarse, the wastewater is introduced into the heat recovery heat exchanger, and the heat exchanged wastewater is discharged through the wastewater discharge pipe, and the preheated water is supplied to the bathhouse, swimming pool, and plant.
상기와 같은 폐수열 회수장치를 지속적으로 사용하기 위해서는 폐수 집수정에 흡착되거나 적층되어 있는 슬러지를 수시로 점검하여 세척해야 하는데, 세척시 폐수 집수정 내부에 장착된 다수개의 필터를 분리하여 개별적으로 세척한 후 재장착하여 사용하게 된다.In order to continuously use the wastewater heat recovery apparatus as described above, sludge adsorbed or stacked in the wastewater sump should be checked and washed from time to time.In the case of washing, after separating a plurality of filters mounted inside the wastewater sump, it is washed separately. It will be refitted and used.
하지만 상기와 같은 필터의 분리 작업은 번거럽고 비위생적일 뿐만 아니라, 소정 시간마다 폐수의 수위를 체크하여 오버플로어를 방지해야 하므로 작업의 효율성이 저하된다. 또한 적정 슬러지 흡착시 즉각적인 세척이 불가능하여 폐수의 열 낭비가 발생할 뿐만 아니라 이로 인하여 열회수율이 감소하는 등의 문제가 발생하였다.However, the separation of such a filter is not only cumbersome and unsanitary, but also prevents overflow by checking the level of wastewater every predetermined time, thereby reducing work efficiency. In addition, it is not possible to immediately wash the adsorption of appropriate sludge, which leads to the waste of heat of the wastewater, thereby reducing the heat recovery rate.
본 고안의 목적은 종래의 이와같은 문제점을 해소하고자 한 데 있는 것으로, 다수개의 필터가 장착되어 내부가 분할 형성되어 있는 폐수 집수정의 일측으로는 수위감지센서를 장착하고, 저면으로는 다수개의 폐수 유출관을 연결 형성하되, 상기 폐수 유출관은 그 관경을 상이하게 형성하고, 각 관로의 종단으로는 주소제변 및 역지변을 장착함으로써, 역세된 폐수를 통해 폐수 집수정 내벽 및 필터에 흡착되어 있는 슬러지를 폐수 유출관으로 용이하게 유출시킬 수 있을 뿐만 아니라, 수위감지센서를 통해 자동으로 슬러지를 제거할 수 있어 슬러지 세척작업이 용이하고, 열회수율을 최대화시킬 수 있는 폐수집수정의 슬러지제거를 위한 역세척장치를 제공코자 하는데 그 목적이 있다.The purpose of the present invention is to solve such a problem in the related art, and is equipped with a water level sensor on one side of the wastewater sump, in which a plurality of filters are mounted to form an internal partition, and a plurality of wastewaters on the bottom. Outflow pipes are connected to each other, and the wastewater outflow pipes are formed to have different diameters, and end of each pipe line is equipped with an address change and a reverse change, so that the wastewater catchment is adsorbed to the inner wall and the filter through the backwashed wastewater. The sludge can be easily discharged to the wastewater outlet pipe, and the sludge can be removed automatically through the water level sensor, making it easier to clean the sludge and maximizing the heat recovery rate. The purpose is to provide a backwash system.
