Embodiment
[0025] Such as figure 1 As shown, the online circulation oil-water separation discharge system of the present invention includes an online oil-water separation circulation system 1, a sewage recovery system 2, a drainage system 3, a PLC electrical control system 4 with a man-machine interface, and a water collection well 5. in:
[0026] Online oil-water separation system 1: includes a deep sewage collection device 104 and an oil-water separation system 102 placed in the water collection well 5. The deep sewage collection device 104 is connected to the oil-water separation system 102 through pipelines. A sewage oil water pump 105 is arranged on the road, and the sewage oil water pump 105 adopts a centrifugal water pump structure. The centrifugal structure overcomes the phenomenon that the traditional sewage pump uses a screw positive displacement pump to start up after shutdown, and often fails to work due to corrosion, jamming, mud and sand entry, etc.; It varies with the li...

The invention discloses an online circulation oil-water separation discharge system, which comprises an online oil-water separation circulation system, a sewage recovery system, a drainage system, a PLC electrical control system with a man-machine interface, and a water collection well. The deep sewage collection device and the oil-water separation system in the well, the deep sewage collection device is connected with the oil-water separation system through pipelines, a sewage oil water pump is arranged on the outlet pipeline of the deep sewage collection device, and a water pump is installed at the entrance of the oil-water separation system An online oil concentration monitoring analyzer, and an automatic flow control valve is respectively provided on the pipeline connected to and connected to the oil-water separation system, and the drainage system includes a drainage pump whose inlet is located at the bottom of the water collection well; the PLC electrical control system and The drainage pump, the sump oil water pump and the sump oil recovery pump circuit connections. The invention can automatically circulate and operate to ensure that the water in the water collection well is always in the discharge state up to the standard, the whole system occupies a small area, and the manufacturing cost is low.
Description
technical field [0001] The invention relates to an online circulating oil-water separation discharge system, which belongs to the technical field of oil-water treatment. Background technique [0002] my country is rich in hydropower resources. There are more than 100,000 large and small hydropower stations nationwide. By the end of 2011, nearly 45,000 small hydropower stations, more than 2,000 small and medium-sized hydropower stations, and nearly 300 large and medium-sized hydropower stations have been built. Since hydropower generation has the characteristics of renewability and pollution-free, the only pollution is oil pollution from leakage water from equipment pipelines and equipment pipeline maintenance discharge water when it is discharged to the outside. Therefore, hydropower generation is widely used. application. [0003] In recent years, due to the strengthening of environmental protection awareness, foreign hydropower stations are equipped with oily sewage disch...
