Technical Field

[0001] This utility model relates to the field of oily wastewater treatment technology, and in particular to a micro-electrolytic degradation treatment device for oily wastewater. Background Technology

[0002] Oily wastewater is wastewater containing oily substances discharged during industrial production processes. The oily substances in oily wastewater include natural petroleum, petroleum products, tar and its fractions, as well as edible animal and vegetable oils and fats. In terms of water pollution, petroleum and tar are the primary pollutants. The concentration of oily substances in wastewater discharged from different industrial sectors varies greatly. When treating oily wastewater, it is usually necessary to separate the floating oil from the water, and then use micro-electrolysis to convert the long carbon chain structure into a more easily degradable short carbon chain structure.

[0003] Currently, when separating oil and water in oily wastewater, the oil content varies, making it difficult to extract the oil. This often results in the oil containing wastewater or incomplete oil separation, leading to poor performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a micro-electrolytic degradation treatment device for oily wastewater, so as to solve the problem that the prior art is not convenient to extract oil due to different oil content in the wastewater, and the oil is prone to contain wastewater or the oil is not completely separated, resulting in poor performance.

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a micro-electrolytic degradation treatment device for oily wastewater according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the micro-electrolysis degradation treatment device for oily wastewater provided by this utility model includes a storage tank 1, a micro-electrolysis reactor 9 fixedly installed on the top of the storage tank 1, a glass plate 2 fixedly installed inside one side of the storage tank 1, an oil pumping mechanism provided between the storage tank 1 and the micro-electrolysis reactor 9, an inlet 3 installed on one side of the storage tank 1 near the top, and a drain pipe 13 installed on the other side of the storage tank 1 near the bottom, with a solenoid valve 14 fixedly installed inside the drain pipe 13;

[0027] The oil extraction mechanism includes an installation cylinder 4, a movable tube 5, an installation tube 8, and a vacuum pump 10. The installation cylinder 4 is fixedly installed inside the liquid storage tank 1. The movable tube 5 is slidably connected inside the installation cylinder 4. The installation tube 8 is fixedly installed at the top connection end of the micro-electrolysis reactor 9. The vacuum pump 10 is fixedly installed at the top of the installation tube 8. The top of the movable tube 5 is connected to the installation tube 8. An installation plate 18 is fixedly installed at the bottom of the movable tube 5.

[0028] It should be noted that the inlet 3 can be used to inject oily wastewater into the storage tank 1. The glass plate 2 can be used to easily observe the thickness of the oil layer in the wastewater inside the storage tank 1. The position of the mounting plate 18 at the bottom of the mounting cylinder 4 can be adjusted according to the thickness of the oil layer so that it is at the contact position of the oil and water layers. Then, the oil inside the storage tank 1 is extracted by the air pump 10 and pumped into the mounting pipe 8. Finally, the oil is transported to the micro-electrolysis reactor 9 through the mounting pipe 8 for micro-electrolysis treatment, thereby improving the oil-water separation effect.

[0029] In some embodiments, such as Figure 2 As shown, the mounting plate 18 is connected to the movable tube 5. An extension 19 is fixedly installed on the side wall of the mounting plate 18. A through hole 20 is opened at the top of the extension 19. The through hole 20 is a tapered hole with a top inner diameter larger than the bottom inner diameter.

[0030] It should be noted that by setting the extension 19, the oil absorption range can be increased, making the oil separation faster. By setting the tapered through hole 20, the oil can be easily drawn into the mounting cylinder 4.

[0031] In some embodiments, such as Figure 2 As shown, a waterproof and breathable membrane 11 is fixedly installed on the inner wall of the installation pipe 8 near the top, and a one-way valve 12 is fixedly installed on the inner wall of the installation pipe 8 near the bottom. A connecting pipe 7 is fixedly installed on the side wall of the installation pipe 8. One end of the connecting pipe 7 is located at the bottom of the waterproof and breathable membrane 11, and a corrugated expansion pipe 6 is fixedly installed on the other end of the connecting pipe 7. The other end of the corrugated expansion pipe 6 is connected to the movable pipe 5.

[0032] It should be noted that by setting up a waterproof and breathable membrane 11, oil can be prevented from entering the vacuum pump 10. By setting up a one-way valve 12, the vacuum pump 10 will not extract the oil from the micro-electrolysis reactor 9 during the vacuuming process. By setting up a corrugated telescopic pipe 6, the connection between the mounting cylinder 4 and the connecting pipe 7 can still be maintained after the height of the mounting cylinder 4 is adjusted.

[0033] Example 2

[0034] In some embodiments, such as Figure 3 As shown, the inner wall of the mounting cylinder 4 has several mounting cavities 15, and the mounting cavities 15 are connected to the locking blocks 16 by springs. The side wall of the movable tube 5 has several locking grooves 17 that fit with the locking blocks 16.

[0035] It should be noted that the spring can be used to support the locking block 16. Both the locking block 16 and the slot 17 are arc-shaped. The locking block 16 can be inserted into the slot 17 to limit the position of the movable tube 5 inside the mounting cylinder 4, thereby facilitating the adjustment of the height of the bottom mounting plate 18 of the fixed movable tube 5.

[0036] The micro-electrolysis reactor 9 in this invention is a known component and will not be described in detail here.

[0037] Working principle: During use, oily wastewater can be injected into the storage tank 1 through the inlet 3. After the oily wastewater settles for a period of time, the thickness of the oil layer in the wastewater inside the storage tank 1 can be observed through the glass plate 2. The position of the mounting plate 18 at the bottom of the mounting cylinder 4 can be adjusted according to the thickness of the oil layer so that the extension 19 on the side wall of the mounting plate 18 is at the contact position of the oil and water layer. Then, the air pump 10 is run to pump air, so that the oil enters the extension 19 through the through hole 20, and then enters the mounting cylinder 4 through the extension 19 and the mounting plate 18. Finally, it is transported to the mounting pipe 8 through the corrugated expansion pipe 6 and the connecting pipe 7. During the air pumping process, the one-way valve 12 can prevent the oil in the micro-electrolysis reactor 9 from being extracted during the air pumping process. After the air pump 10 stops running, the oil can enter the micro-electrolysis reactor 9 through the one-way valve 12 to carry out micro-electrolysis reaction, so that it changes from a long carbon chain structure to a short carbon chain structure that is easy to degrade, thereby facilitating treatment.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
