Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a membrane contact oxidation device for wastewater treatment. Background Technology

[0002] Membrane contact oxidation technology is a highly efficient wastewater treatment process that combines membrane separation technology with biological oxidation. It utilizes hollow fiber membranes in a membrane contact reactor to fully oxidize organic matter in wastewater under the action of ozone, thereby removing organic matter and color. This technology promotes full contact between ozone and wastewater through the jet action of an ozone generator, improving oxidation efficiency.

[0003] In the "Membrane Contact Oxidation Device for Deep Treatment of Wastewater" with authorization announcement number "CN215049298U", wastewater is filtered through multiple stages by a filter before entering the oxidation reactor to oxidize organic pollutants in the wastewater. However, after the filter screen filters the wastewater for a long time, it will contain a large amount of waste, which will affect the filtration effect of the wastewater under long-term use. At the same time, several hollow fiber membranes are set between the connecting seat and the liquid collection hood, which makes it inconvenient to replace the hollow fiber membranes. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a membrane contact oxidation device for wastewater treatment includes an oxidation reaction shell 1. A flow guide shell 2 is fixedly installed on the top of the oxidation reaction shell 1. Filter screens 3 are fixedly installed at equal intervals in the middle of the flow guide shell 2. There are three filter screens 3. A connecting rod 4 is fixedly installed between the middle of the three filter screens 3. The connecting rod 4 is movable. A discharge port 5 is opened on the flow guide shell 2 corresponding to the top position of the filter screens 3. A waste collection hood 6 is fixedly installed on the top of the oxidation reaction shell 1. A connecting seat 7 is movably installed in the middle of the waste collection hood 6. A liquid collection hood 8 is fixedly installed at the bottom of the middle of the inner wall of the oxidation reaction shell 1. An installation frame 9 is movably installed between the connecting seat 7 and the liquid collection hood 8. Multiple hollow fiber membranes 10 are arranged on the installation frame 9. The 10 are arranged in a ring array. After the filter screen 3 has been used to filter wastewater for a long time, the connecting rod 4 is driven to rise, which will change the filter screen 3 from a bent downward state to a bent upward state. At the same time, the waste on the filter screen 3 will be discharged from the discharge port 5 through the surface of the filter screen 3, thus cleaning the filter screen 3. After the hollow fiber membrane 10 has been used for a long time, the connecting seat 7 is pushed upward to remove the limiting effect of the connecting seat 7 on the mounting frame 9 on which the hollow fiber membrane 10 is installed. The mounting frame 9 on which the hollow fiber membrane 10 is installed can be removed from between the connecting seat 7 and the liquid collection hood 8. Then the mounting frame 9 on which the hollow fiber membrane 10 is installed is installed between the connecting seat 7 and the liquid collection hood 8, which will drive the connecting seat 7 to be stably locked on the top of the mounting frame 9 on which the hollow fiber membrane 10 is installed, so that the hollow fiber membrane 10 can be installed.

[0022] like Figures 1 to 4As shown, a hydraulic rod 11 is fixedly installed on the top of the flow guide housing 2. The moving end of the hydraulic rod 11 is fixedly connected to the connecting rod 4. A waste collection box 12 is slidably installed on the outer side of the flow guide housing 2 at the position corresponding to the discharge port 5. The inner ring of the waste collection box 12 can block the discharge port 5. The three waste collection boxes 12 are fixedly connected to each other. A connecting frame 13 is fixedly installed on the moving end of the hydraulic rod 11. The connecting frame 13 is fixedly connected to the waste collection box 12.

[0023] The hydraulic rod 11 drives the connecting rod 4 to rise, and the hydraulic rod 11 also drives the waste collection box 12 to slide and rise along the outside of the guide shell 2, thus removing the obstruction of the discharge port 5 by the waste collection box 12. At the same time, the waste will flow into the interior of the waste collection box 12, realizing the collection of waste.

[0024] like Figures 1 to 4 As shown, a waste discharge pipe 14 is fixedly installed in the middle of the waste collection box 12.

[0025] Waste inside the waste collection box 12 can be discharged through the waste discharge pipe 14.

[0026] like Figures 1 to 4 As shown, the waste collection cover 6 has sliding holes 15 arranged in a ring around the central axis of the waste collection cover 6. Sliding rods 16 are slidably installed inside the sliding holes 15. The bottoms of the four sliding rods 16 are fixedly connected to the connecting seat 7. A spring 17 is sleeved on the outer side of the bottom end of the sliding rod 16. One end of the spring 17 is fixedly connected to the connecting seat 7, and the other end of the spring 17 is fixedly connected to the lower surface of the waste collection cover 6.

[0027] Pushing the connecting seat 7 upwards will cause the slide rod 16 to slide inside the sliding hole 15, thus removing the limiting effect of the connecting seat 7 on the mounting bracket 9 on which the hollow fiber membrane 10 is installed. The mounting bracket 9 on which the hollow fiber membrane 10 is installed can be removed from between the connecting seat 7 and the liquid collection hood 8. The mounting bracket 9 on which the hollow fiber membrane 10 is installed can be installed between the connecting seat 7 and the liquid collection hood 8. The spring 17 pushes the connecting seat 7, which can drive the connecting seat 7 to be stably locked on the top of the mounting bracket 9 on which the hollow fiber membrane 10 is installed, so that the hollow fiber membrane 10 can be installed.

[0028] like Figures 1 to 4 As shown, liquid guide pipes 18 are fixedly installed on the top of the four slide rods 16, and the liquid guide pipes 18 are slidably installed in the middle of the waste collection hood 6.

[0029] Waste liquid above the waste collection hood 6 can be diverted from the liquid guide pipe 18 to the hollow fiber membrane 10 via the connection of the liquid guide pipe 18 for guiding the waste liquid.

[0030] This utility model provides a membrane contact oxidation device for wastewater treatment, the specific working principle of which is as follows:

[0031] Ozone is first introduced into the oxidation reaction shell 1. Then, wastewater enters the flow guide shell 2 through the top of the flow guide shell 2. The wastewater undergoes multi-stage filtration through three filter screens 3. After filtration, the wastewater enters the oxidation reaction shell 1, passes through the waste collection hood 6, then through the connecting seat 7 connected to the waste collection hood 6, several hollow fiber membranes 10, and the liquid collection hood 8, and is discharged from the liquid collection hood 8. Ozone enters the oxidation reaction shell 1 and is propelled into the hollow fiber membrane 10 through the micropores generated by the flow of wastewater within the hollow fiber membrane 10. The ozone then fully contacts and mixes with the wastewater within the hollow fiber membrane 10, thereby oxidizing the wastewater and performing deep treatment of the wastewater.

[0032] After the wastewater is filtered for a long time using filter screen 3, the connecting rod 4 is raised by hydraulic rod 11, which will change the filter screen 3 from a bent downward state to a bent upward state. At the same time, hydraulic rod 11 will also drive the waste collection box 12 to slide upward along the outside of the guide shell 2, removing the obstruction of the discharge port 5 by the waste collection box 12. The waste on the filter screen 3 will be discharged from the discharge port 5 through the surface of the filter screen 3 and will flow into the interior of the waste collection box 12, thus cleaning the filter screen 3 and collecting the waste.

[0033] After prolonged use of the hollow fiber membrane 10, pushing the connecting seat 7 upwards will cause the slide rod 16 to slide inside the sliding hole 15, thus removing the limiting effect of the connecting seat 7 on the mounting bracket 9 with the hollow fiber membrane 10 installed. The mounting bracket 9 with the hollow fiber membrane 10 installed can then be removed from between the connecting seat 7 and the liquid collection hood 8. After cleaning the hollow fiber membrane 10 or installing a new hollow fiber membrane 10, pushing the connecting seat 7 upwards will install the mounting bracket 9 with the hollow fiber membrane 10 installed between the connecting seat 7 and the liquid collection hood 8. The spring 17 pushes the connecting seat 7, which can stably lock the connecting seat 7 onto the top of the mounting bracket 9 with the hollow fiber membrane 10 installed, allowing the hollow fiber membrane 10 to be installed.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
