Description

Technical Field

[0001] The utility model relates to the technical field of coalescence plate filler flotation, in particular to an air flotation device with coalescence plate filler. Background Art

[0002] Coalescing plate packing increases the oil-water contact area, causing oil droplets to collide and aggregate within the packing, accelerating the separation process. This design not only improves oil-water separation efficiency but also reduces the use of chemical agents. Combining coalescing with flotation can significantly improve oil-water separation efficiency. While coalescing alone can effectively remove some oil droplets, its efficiency is relatively low. Combining coalescing materials with flotation equipment can achieve higher oil removal efficiency in a shorter time.

[0003] In application number: CN201820168329.2, a compact cyclone flotation device with a sand removal structure is disclosed, which includes an outer cavity and an inner cavity arranged inside the outer cavity. The sand removal cone is connected to the bottom of the outer cavity, and a cyclone generator is provided at the connection between the sand removal cone and the inner cavity. An annular agglomeration plate is installed on the upper part of the inner cavity. The sand removal cone structure can effectively remove a small amount of solid particles in the oily wastewater, reduce the impact of solids on the separation efficiency and improve the service and maintenance life of the equipment. The initial cyclone increases the probability of adhesion, providing better conditions for the next step of oil-water separation.

[0004] However, this device cannot guarantee that the oil and water can be completely separated in one go. The clean water discharged from the clean water outlet needs to be further tested. If there is still oil in the water, the water can be passed into the flotation device again for oil-water separation until the discharged clean water does not contain oil. Therefore, a flotation device with a coalescing plate filler is proposed. Utility Model Content

[0005] In response to the problems in the existing technology, the utility model provides a flotation device with a coalescing plate filler, which can detect the oil content of the discharged clean water and circulate it into the flotation device for multiple oil-water separations, thereby improving the oil-water separation effect.

[0006] The technical solution adopted by the utility model to solve the technical problem is an air flotation device with a coalescing plate filler, comprising an air flotation device body and a circulation detection device, one side of the air flotation device body is fixedly connected to one end of a second connecting pipe, the other end of the second connecting pipe is fixedly connected to one side of the circulation detection device, and the interior of the air flotation device body is connected to the interior of the circulation detection device through the second connecting pipe;

[0008] By adopting the above technical solution, the separated clean water is discharged into the circulation detection device and tested by the oil pollution detector. If it contains oil, it is further discharged into the flotation device body to repeat the oil-water separation. If there is no oil, it is discharged from the water outlet pipe, which further improves the oil-water separation effect.

[0009] Specifically, the outer side of the first connecting pipe is fixedly connected to one end of the water inlet pipe and is internally connected, and the outer side of the water inlet pipe is sleeved with a third valve.

[0010] By adopting the above technical solution, the third valve is opened to discharge the oily wastewater through the water inlet pipe, and the oily wastewater is discharged from the first connecting pipe into the sand removal cone for sand removal.

[0011] Specifically, the outer side of the second connecting pipe close to the flotation device body is sleeved with a fourth valve, the outer side of the first connecting pipe close to the outlet pipe is sleeved with a second valve, and the outer side of the outlet pipe is sleeved with a first valve below the second valve.

[0012] By adopting the above technical solution, the fourth valve is opened to allow the water inside the flotation device body to be discharged from the second connecting pipe into the detection chamber in the circulation detection device. The second valve is opened to allow the water in the detection chamber to be discharged from the first connecting pipe into the sand removal cone again, repeating the oil-water separation. The first valve is opened to discharge the water from the circulation detection device.

[0013] Specifically, a detection cavity is provided inside the circulation detection device, and an observation window is provided outside the circulation detection device.

[0014] By adopting the above technical solution, the water capacity inside the detection cavity can be seen from the observation window.

[0016] Beneficial effects of the utility model:

[0017] The utility model discloses an air flotation device with a coalescing plate filler, which discharges the separated clean water into a circulation detection device for detection by an oil pollution detector. If the clean water contains oil, it is continuously discharged into the air flotation device body to repeat the oil-water separation.
