Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and more specifically to a treatment system for acid-containing heavy crude oil refining wastewater. Background Art

[0002] The acidic heavy crude oil refining wastewater treatment unit is a special equipment for treating wastewater generated during the refining process of high acidic heavy crude oil. This kind of wastewater usually has the characteristics of high COD, high oil content, high ammonia nitrogen, high conductivity, and contains polar pollutants such as organic acids, esters, alcohols, and heterocyclic compounds, so it is difficult to treat.

[0003] The current acid-containing heavy crude oil refining wastewater treatment system usually needs to remove solid matter in the wastewater first, then separate grease and suspended matter, and finally use microbubble technology to combine oil and suspended matter in the wastewater to form a floating body, which floats to the water surface and is removed. This series of operations is highly dependent on the collaborative operation of multiple devices. Therefore, the existing system often requires a large amount of equipment and human resources. However, this treatment method also causes a series of problems. First, the complexity of equipment use and maintenance costs have increased significantly. Due to the wide variety of equipment in the system and the high degree of technical integration, daily maintenance and troubleshooting have become extremely cumbersome, which not only increases maintenance costs, but also poses a challenge to the company's operational efficiency. Secondly, the coordinated operation of multiple devices has become another problem. In order to ensure the smooth operation of the system, it is necessary to accurately control the time control and parameter adjustment between each device, which undoubtedly increases the complexity of the system operation. Once a device fails or the parameters are improperly set, it may cause a chain reaction in the entire treatment process, affecting the overall treatment efficiency. In view of this, we propose a treatment system for acid-containing heavy crude oil refining wastewater. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention designs a docking component, a processing component and an air flotation component. When performing air flotation treatment, the driver needs to be operated counterclockwise. Similarly, when rotating clockwise, the driving component will synchronously drive several processing components to rotate through the docking component, so that the wastewater in the processing component is centrifugally treated, so that the device can not only quickly switch between the air flotation treatment method and the centrifugal treatment method of wastewater, but also the above-mentioned operation process only requires personnel to control the clockwise and counterclockwise operation of the device accordingly, which reduces the device's demand for human resources and personnel's operating proficiency, thereby reducing the complexity and maintenance cost of the device when in use, and thus ensuring the efficiency of the device in treating wastewater.

[0017] 2. The present invention also designs an air flotation component. When the paddle-shaped blades rotate in the fluid, they will promote the flow of the fluid. The shape and angle of the blades are designed so that they can exert force on the surrounding fluid during the rotation process, thereby causing the fluid to flow in a directional manner. As the blades rotate, the fluid is divided into two parts. One part rotates with the paddles to form a rotating layer, and the other part is farther away from the paddles and has a slower speed, forming a stationary layer. On the shear surface, due to the speed difference between the rotating layer and the stationary layer, a strong shearing effect will be generated. This shearing effect will cause the fluid to generate vortices and turbulence near the shear surface, thereby accelerating the generation of bubbles. In addition, the convection of the liquid can be accelerated by relatively arranging multiple stirring blades, further improving the air flotation treatment effect of the device on wastewater.

[0018] 3. The present invention also designs a processing component and a docking component. When the driving rod is rotated clockwise, the driving rod will drive several first docking blocks to contact the vertical surface of the second docking block through the vertical surface, thereby driving the docking shell to rotate. At the same time, the one-way slider under the docking shell will synchronously squeeze the arc-shaped gasket, causing the arc-shaped gasket to deform. At this time, since the docking shell will synchronously drive several processing bins to rotate when rotating, several relatively independent processing bins can collect wastewater while centrifugally treating wastewater, avoiding wastewater leakage, and at the same time reducing the difficulty of switching the device between flotation treatment and centrifugal treatment of wastewater, further ensuring the treatment effect of the device on wastewater.

[0025] As another embodiment of the present invention, the air flotation component 207 includes a bearing 2071, a rotating shaft 2072 is sleeved in the bearing 2071, one end of the rotating shaft 2072 is fixedly connected to the second bevel gear 2073, and the other end of the rotating shaft 2072 passes through the bearing 2071 and is fixedly connected to a plurality of stirring blades 2074, the stirring blades 2074 are three-wing or four-wing paddle-shaped blades, the bearing 2071 is clamped in the docking shell 2051, and the plurality of stirring blades 2074 are all located in the processing chamber 2061, the second bevel gear 2073 is meshed with the first bevel gear 2022, and the limiting component 208 includes a mounting seat 2081.

As the blades rotate, the fluid is divided into two parts, one part rotates with the blades to form a rotating layer, and the other part is farther away from the blades and has a slower speed, forming a stationary layer. On the shear surface, due to the speed difference between the rotating layer and the stationary layer, a strong shearing effect will be generated.

Since the filling block 2091 is provided and a guide inclined groove 2092 is provided above the filling block 2091, when waste water drops on the filling block 2091, the filling block 2091 can guide the waste water to flow along the guide inclined groove 2092 to the processing bins 2061 on both sides, ensuring that the waste water entering the protective shell 101 can flow into the processing bin 2061.

[0027] Working principle: This embodiment provides a treatment system for acid-containing heavy crude oil refining wastewater. When in use, the wastewater needs to be injected into the protective housing 101 through the feed port 103, and then the wastewater is subjected to flotation and centrifugal treatment by adjusting the clockwise and counterclockwise operation of the driver 201. After the treatment is completed, the discharge port below is opened to discharge the wastewater; When wastewater is injected into the device, a large amount of wastewater will directly fall on the solid-liquid separation component 203. At this time, the solid-liquid separation component 203 will separate the solid solid material and liquid material of the wastewater. The liquid material will directly pass through the solid-liquid separation component 203 and enter the processing component 206, while the solid material will be retained in the solid-liquid separation component 203. When flotation treatment is performed, the driver 201 needs to be operated counterclockwise. At this time, the driving component 202 will drive the second bevel gear 2073 to rotate, and the limiting component 208 below will block the rotation of the docking component 205, so that the flotation component 207 set in the docking component 205 will rotate quickly, thereby accelerating the generation and hedging of bubbles, so as to flotation treatment of the wastewater. Similarly, when rotating clockwise, the driving component 202 will synchronously drive several processing components 206 to rotate through the docking component 205, so that the wastewater in the processing component 206 is centrifugally treated; When wastewater enters the device, the filter cover 2031 will filter the solid matter in the wastewater, so that the solid waste will be retained above the filter cover 2031. When the driver 201 drives the driving rod 2021 to rotate, since the filter cover 2031 is slidably connected to the outside of the driving rod 2021, the filter cover 2031 will rotate synchronously. At this time, during the rotation of the filter cover 2031, the lower protrusion 2033 of the filter cover 2031 will continue to contact the pulley, so that the pulley squeezes the protrusion 2033 and pushes the filter cover 2031 upward as a whole. When the pulley contacts the guide groove 2032, the filter cover 2031 is reset under the action of its own weight and the weight of the counterweight block 2034. When the device is operated counterclockwise, the driving rod 2021 will rotate counterclockwise. Since the first docking block 2024 and the second docking block 2052 are in arc surface contact, the first docking block 2024 will squeeze the first elastic telescopic rod 2023 when in contact, causing the first telescopic rod to shrink, and the lower one-way slider 2053 will contact the straight surface of the arc gasket 2082, causing a stuck situation. At this time, the docking shell 2051 is in a fixed state, so that the positions of the several processing bins 2061 are fixed, and as the stirring rod continues to drive the first bevel gear 2022 to rotate, the second bevel gear 2073 will synchronously drive the rotating shaft 2072 to rotate due to the drive of the first bevel gear 2022. At this time, the several stirring blades 2074 outside the rotating shaft 2072 will stir the wastewater in the processing bin 2061. When the driving rod 2021 is rotated clockwise, the driving rod 2021 will drive several first docking blocks 2024 to contact the vertical surface of the second docking block 2052 through the vertical surface, thereby driving the docking shell 2051 to rotate. At the same time, the one-way slider 2053 under the docking shell 2051 will synchronously squeeze the arc-shaped gasket 2082, causing the arc-shaped gasket 2082 to deform. At this time, since the docking shell 2051 will synchronously drive several processing bins 2061 to rotate when rotating, the relatively independent processing bins 2061 can centrifuge the wastewater while collecting the wastewater.
