[0002] Thermal power plants are the main source of electricity in my country and also one of the main sources of pollution. In terms of green development, environmental protection and energy conservation and emission reduction rely more on the wastewater treatment methods of thermal power plants. Among them, the source of oily wastewater in power plants is mainly wastewater from oil storage tanks, pump rooms, and cleaning of floors and equipment. The main sources of pollution in wastewater are oil substances and suspended solids.

[0003] Usually, when treating oily wastewater, there is a way to mix the deoiled liquid with the oily wastewater to achieve a filtering effect. Generally, the oily wastewater is directly poured into the reactor, and then the deoiled liquid is poured into the reactor. In this way, it is difficult for the oily wastewater to fully blend and react with the deoiled liquid, and the oil removal efficiency is poor. Therefore, it does not meet the existing needs. In this regard, we have proposed an oily wastewater filtration device for thermal power plants. Utility Model Content

[0012] 1. Pour the oily wastewater to be treated into the filter housing. With the cooperation of the motor, the connecting shaft, the first gear, the second gear and the stirring rod, the stirring rod drives several mixing rods to rotate together. The mixing rod can drive the oily wastewater to rotate. At this time, the deoiling liquid can enter the interior of the mixing rod through the stirring rod. Through the centrifugal force of the stirring rod, the liquid is thrown out through the dispersion pipe on the mixing rod. Because the mixing rods are distributed in the filter housing, the deoiling liquid can be fully contacted with the oily wastewater in all directions to ensure that the two can fully react and ensure the efficiency of oil removal.

[0013] 2. With the cooperation of the infusion hole, cylinder, piston, stirring rod, conveying pipeline and baffle, the deoiled liquid will enter the conveying pipeline through the infusion hole. The movement of the piston will give the liquid a certain pushing force. The deoiled liquid enters the inner cavity of the mixing rod through the inner cavity of the stirring rod. The pressure brought by the movement of the piston causes the liquid to pass through the dispersion pipe on the mixing rod. When the liquid passes through the dispersion pipe, it will drive the turbine blades to rotate. The rotation of the turbine blades will cause the liquid to rotate, causing the liquid to flow out in a vortex, and come into contact with the oily wastewater. Through the distribution of the mixing rod and the dispersion pipes in multiple places, the deoiled liquid can be further fully integrated and reacted with the oily wastewater.

[0022] The driving assembly 6 includes a motor 61 fixedly mounted on the upper end of the filter housing 1 and a connecting shaft 62 arranged at the output end of the motor 61. A first gear 63 is fixedly mounted on the upper end of the connecting shaft 62, and a second gear 64 is fixedly mounted on the axial side wall of the stirring rod 8. The rotation of the stirring rod 8 can stir the oily wastewater and generate centrifugal force, so that the deoiled liquid can be better thrown out from the stirring rod 8.

[0023] In this embodiment: first, pour the oily wastewater to be treated into the filter housing 1, turn on the motor 61, which drives the first gear 63 to rotate through the connecting shaft 62, and the first gear 63 drives the stirring rod 8 to rotate through the second gear 64. The stirring rod 8 drives several mixing rods 7 to rotate together, and the mixing rod 7 can drive the oily wastewater to rotate. At this time, the deoiling liquid can enter the interior of the mixing rod 7 through the stirring rod 8. As the external deoiling liquid continuously enters the interior of the hollow structure stirring rod 8, the deoiling liquid will pass through each mixing rod 7. Through the centrifugal force of the stirring rod 8, the liquid is thrown out through the dispersion pipe 10 on the mixing rod 7.

[0024] Example 2

[0025] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 and Figure 4 The pushing component 5 includes a delivery pipe 55 arranged at the upper end of the stirring rod 8 and an infusion hole 9 opened on the delivery pipe 55. A piston 52 is slidably arranged on the delivery pipe 55. The piston 52 is arranged below the infusion hole 9. Through the setting of the piston 52, the degreasing liquid can be squeezed, so that the degreasing liquid can be better separated from the stirring rod 8.

[0026] A baffle 56 is fixedly mounted on the upper end of the piston 52 . The baffle 56 is in contact with the infusion hole 9 in an initial state. By setting the baffle 56 , in the initial position, it can block the infusion hole 9 to prevent the degreasing liquid from entering the delivery pipe 55 .

[0027] An L-shaped panel 54 is fixedly mounted on the upper end of the filter housing 1 , a connecting rod 53 is fixedly mounted on the upper end of the L-shaped panel 54 , a cylinder 51 is fixedly mounted on the side wall of the connecting rod 53 , and the upper end of the piston 52 is fixedly connected to the telescopic end of the cylinder 51 .

[0028] A connecting panel 13 is rotatably provided on the dispersion pipe 10, a rotating shaft 11 is fixedly installed on one end of the connecting panel 13, and a turbine blade 12 is fixedly installed on the axial side wall of the rotating shaft 11. Through the setting of the turbine blade 12, the deoiling liquid can be rotated to allow it to better contact the oily wastewater.

[0029] In this embodiment, the infusion hole 9 is connected to an external degreasing liquid source, the cylinder 51 is turned on, and the cylinder 51 drives the piston 52 to slide in the inner cavity of the stirring rod 8 and the delivery pipe 55 through its telescopic end, and the piston 52 drives the baffle 56 to slide upward. When the baffle 56 is separated from the infusion hole 9, the degreasing liquid will enter the delivery pipe 55 through the infusion hole 9, and then enter the inner cavity of the stirring rod 8 again through the delivery pipe 55. When the cylinder 51 drives the piston 52 to push downward, the piston 52 will push the liquid to a certain extent. The oil-removing liquid enters the inner cavity of the mixing rod 7 through the inner cavity of the stirring rod 8 by the dynamic force. The pressure brought by the movement of the piston 52 causes the liquid to pass through the dispersion pipe 10 on the mixing rod 7. When the liquid passes through the dispersion pipe 10, it drives the turbine blades 12 to rotate. The rotation of the turbine blades 12 causes the liquid to rotate, causing the liquid to flow out in a vortex, and come into contact with the oily wastewater. Through the distribution of the mixing rod 7 and the dispersion pipe 10 at multiple locations, the oil-removing liquid can further fully blend and react with the oily wastewater.
