Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an electro-adsorption device for removing emulsified oil from wastewater. Background Technology

[0002] Due to the persistence and stubbornness of heavy metals in the environment, effectively removing heavy metals from wastewater has become a major challenge. Common methods for treating pollutants in water include chemical precipitation, membrane separation, electrodeposition, ion exchange, cementation, and adsorption. Adsorption is one of the most frequently used methods for removing metal ions. Methods for adsorption treatment of heavy metals in wastewater include electro-adsorption technology and reverse osmosis. Among these, electro-adsorption technology (also known as capacitive deionization technology) has advantages such as low pressure, room temperature, low energy consumption, low cost, no secondary pollution, and easy regeneration. It can be used to remove salts or metal ions from water and is a very promising emerging technology for treating heavy metals in water. Because it uses electricity as the driving force, it effectively avoids the use of chemical reagents, prevents secondary pollution, and has good prospects for industrial application.

[0003] However, when the concentration of suspended solids in the wastewater is high or the wastewater quality is complex, the traditional air flotation method for oil removal is prone to causing equipment and pipeline blockage, which is also difficult to clean.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an electro-adsorption device for removing emulsified oil from wastewater. Utility Model Content

[0005] The purpose of this invention is to provide an electro-adsorption device for removing emulsified oil from wastewater, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electro-adsorption device for removing emulsified oil from wastewater, comprising a reaction tank and a cleaning component. The inner wall of the reaction tank is provided with an electro-adsorption plate. The cleaning component for continuous enrichment, transportation, and cleaning of emulsified oil is located in the middle of the reaction tank. The cleaning component includes a power shaft, a track, a brush, an oil scraper, and a collection platform. The outside of the power shaft is provided with a track, and the surface of the track is provided with a brush. An oil scraper is located above the right side of the brush, and a collection platform is located below the oil scraper.

[0007] Furthermore, the track and the brush are fixedly connected, and the brushes are linearly and equidistantly distributed about the track surface.

[0008] Furthermore, an inlet is provided at the lower left end of the reaction tank, and an outlet is provided at the upper right end of the reaction tank.

[0009] Furthermore, a stirrer is provided at the lower end of the reaction tank, and a slag discharge port is provided on the surface of the collection platform.

[0010] Furthermore, a control frame is provided on the outer side of the collection platform, and a hydraulic rod is provided on the side of the control frame.

[0014] This invention provides an electroadsorption device for removing emulsified oil from wastewater, which has the following beneficial effects:

[0015] 1. This utility model features an electro-adsorption plate with minimal restriction, which can simultaneously adsorb multiple metal and salt ions during oil removal, improving the quality of the effluent. The power shaft is driven by a motor to rotate the track, and the brush rotates with the track. The brush sweeps the emulsified oil on the surface of the electro-adsorption plate to the oil scraper for removal and cleaning, avoiding oil adhesion on the surface of the electro-adsorption plate from affecting the subsequent adsorption effect and preventing the electrode surface from becoming crowded, thus improving the operating efficiency of the equipment. The emulsified oil is scraped off by the oil scraper and stored in the collection tray, achieving rapid oil removal and automatic collection.

[0016] 2. This utility model uses an inlet for wastewater to enter, and the slag discharge port and the connecting port are connected to allow emulsified oil to be collected into the collection box. The hydraulic rod controls the movement of the collection platform by extension and retraction, so as to avoid the collection platform affecting the movement of the brush. When the collection platform moves at the top of the collection box, the inclined plate and the auxiliary plate move synchronously on the reinforcing rod inside the connecting port to avoid blockage caused by emulsified oil, etc. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, an electro-adsorption device for removing emulsified oil from wastewater includes a reaction tank 1 and a cleaning component 3. An electro-adsorption plate 2 is installed on the inner wall of the reaction tank 1. The electro-adsorption plate 2 uses a less restrictive electro-adsorption method and can simultaneously adsorb multiple metal and salt ions during oil removal, improving the quality of the effluent. The cleaning component 3, used for continuous enrichment and handling of emulsified oil, is located in the middle of the reaction tank 1. The cleaning component 3 includes a power shaft 301, a track 302, brushes 303, an oil scraper 304, and a collection platform 305. The track 302 is installed outside the power shaft 301. The power shaft 301 is driven by a motor to rotate the track 302. The track 302 and brushes 303 are fixedly connected, and the brushes 303 are linearly and equidistantly distributed about the surface of the track 302. A brush 303 is provided on the surface of the 302. The brush 303 rotates with the conveyor belt 302 and sweeps the emulsified oil on the surface of the electro-adsorption plate 2 to the scraper 304 for scraping and cleaning. This prevents oil from adhering to the surface of the electro-adsorption plate 2 and affecting the subsequent adsorption effect, and avoids crowding of the electrode surface space, thereby improving the operating efficiency of the equipment. The scraper 304 is provided above the right side of the brush 303, and a collection platform 305 is provided below the scraper 304. The emulsified oil is scraped off by the scraper 304 and stored in the collection platform 305, realizing rapid oil removal and automatic collection. A water inlet 4 is provided at the lower left side of the reaction tank 1 for the entry of wastewater, and a water outlet 13 is provided at the upper right side of the reaction tank 1. A stirrer 5 is provided at the lower inside the reaction tank 1.

[0023] like Figure 3As shown, the surface of the collecting platform 305 is provided with a slag discharge port 6, which communicates with the connecting port 10 to collect emulsified oil into the collecting box 9. A control frame 7 is provided on the outside of the collecting platform 305, and a hydraulic rod 8 is provided on the side of the control frame 7. The hydraulic rod 8 controls the movement of the collecting platform 305 by extension and retraction to prevent the collecting platform 305 from affecting the movement of the brush 303. The collecting box 9 is installed at the fixed end of the hydraulic rod 8, and a connecting port 10 is provided on the top of the collecting box 9. A reinforcing rod 11 is provided inside the connecting port 10, and an auxiliary component 12 for anti-clogging is provided outside the reinforcing rod 11. The auxiliary component 12 includes an inclined plate 1201 and an auxiliary plate 1202, and the auxiliary plate 1202 is installed on the side of the inclined plate 1201. When the collecting platform 305 moves on the top of the collecting box 9, the inclined plate 1201 and the auxiliary plate 1202 move synchronously on the reinforcing rod 11 inside the connecting port 10 to prevent emulsified oil and other substances from causing blockage.

[0024] In summary, this electro-adsorption device for removing emulsified oil from wastewater firstly... Figures 1-3 The structure shown in the diagram involves transporting wastewater to the reaction tank 1 through the inlet 4. Then, the electro-adsorption device and stirrer 5 are activated. Emulsified oil in the wastewater accumulates on the electro-adsorption plate 2. The electro-adsorption method used on the electro-adsorption plate 2 has few limitations and can simultaneously adsorb multiple metal and salt ions during oil removal, improving the quality of the effluent. Then, the power shaft 301 is activated, driving the track 302. The brushes 303 on the track 302 sweep the emulsified oil on the surface of the electro-adsorption plate 2 to the scraper 304 for removal, preventing oil adhesion on the surface of the electro-adsorption plate 2 from affecting subsequent adsorption effects and avoiding overcrowding of the electrode surface. To improve equipment operating efficiency, as the track 302 rotates, the brush 303, which is covered with emulsified oil, is scraped off by the oil scraper 304 and stored in the collection platform 305, achieving rapid oil removal and automatic collection. The hydraulic rod 8 controls the movement of the collection platform 305 by telescopic control, preventing the collection platform 305 from affecting the movement of the brush 303. The emulsified oil is collected into the collection box 9 through the slag discharge port 6 and the connection port 10. When the collection platform 305 moves on the top of the collection box 9, the inclined plate 1201 and the auxiliary plate 1202 move synchronously on the reinforcing rod 11 inside the connection port 10, preventing the emulsified oil and other substances from causing blockage.
