Description

Technical Field

[0001] This application relates to the technical field of leachate treatment equipment, and in particular to an advanced leachate oxidation device. Background Technology

[0002] Leachate treatment involves processes such as air flotation coagulation sedimentation tanks, advanced oxidation, a primary DTRO system, an intermediate water tank, a stripping tower, and a tertiary high-pressure desalination system. Advanced oxidation technology utilizes hydroxyl radicals with high redox potentials to oxidize large organic molecules in the water, thus efficiently treating recalcitrant organic matter in the leachate. During the advanced oxidation reaction, this technology continuously generates a large number of hydroxyl radicals, which relentlessly attack organic pollutants in the leachate until they are degraded into harmless carbon dioxide, water, and their associated mineral salts.

[0003] A Chinese patent with publication number CN216191595U discloses an advanced oxidation device, including a main tower. The main tower adopts a barrel structure, which is divided into multiple zones by columns, a first partition, a second partition, a third partition, a fourth partition, and a fifth partition. The wastewater inlet pipe, the acidity adjustment zone, the iron salt dissolution zone, the Fenton reaction zone, the pH adjustment zone, the flocculation zone, and the wastewater outlet pipe are connected sequentially along the wastewater treatment direction to facilitate the treatment of wastewater in each zone.

[0004] Regarding the aforementioned technologies, the inventors discovered that the main tower structure used in the advanced oxidation equipment is fixed, making it impossible to flexibly divide the equipment into zones according to actual needs. Furthermore, the multi-zone tank structure makes it difficult to clean the inside of the tank, resulting in inconvenience in use. Utility Model Content

[0005] To achieve flexible adjustment of the usage area of ​​the tank and easy internal cleaning, this application provides an advanced leachate oxidation device.

[0006] The leachate advanced oxidation device provided in this application adopts the following technical solution:

[0007] An advanced leachate oxidation device includes a multi-space treatment tower, which consists of two interlocking shells connected by a locking mechanism. Each shell includes a semi-annular base plate, an arc-shaped shell, and a central shell. The arc-shaped shell is located on the outer side of the semi-annular base plate, and the central shell is located on the inner side of the semi-annular base plate. The semi-annular base plate, the arc-shaped shell, and the central shell are integrally formed. A detachable partition frame is installed between the arc-shaped shell and the central shell. A snap-on cover is installed at the head of the central shell, which engages and is fixedly attached to the central shell. A positioning bracket is fixedly installed between the snap-on cover and the arc-shaped shell.

[0008] By adopting the above technical solution, the multi-space treatment tower is designed as two interlocking shell structures. This allows for quick and easy installation by simply snapping them together when needed, and securing them with locking devices at both ends. When not in use, the two shells can be disassembled, making it easier to clean their interiors individually. The shell design incorporates a semi-annular base plate, an arc-shaped shell, and a central shell. For ease of use, the semi-annular base plate serves as the bottom of the oxidation equipment, ensuring stable placement. The arc-shaped shell acts as the outer shell, and the central shell as the inner shell. When the two shells are interlocked, the two central shells form a central cylindrical structure. Two arc-shaped shells can be joined to form an integral outer shell structure. Once the overall structure of the multi-space processing tower is fixed, several partition frames can be installed to divide its internal space for use, ensuring that processing can be carried out in different spaces. The partition frames are designed to be installed between the arc-shaped shells and the central shell, which is easy to connect and use flexibly as needed, ensuring greater flexibility in use. By installing a snap-on cover at the head of the central shell, the two ends of the central shell can be fixed together during use, which further increases the overall stability of the multi-space processing tower. At the same time, by fixing a positioning bracket between the snap-on cover and the arc-shaped shell, it is convenient to install mixing equipment, etc., through the positioning bracket during use.

[0009] Optionally, the arc-shaped shell includes a main shell plate and connecting strips, wherein the connecting strips are disposed at both ends of the main shell plate and are integrally formed with the main shell plate.

[0010] By adopting the above technical solution, the structure of the arc-shaped shell is designed to ensure that connecting strips can be installed at both ends of the main shell plate during use. In this way, the connecting strips at both ends can be fastened together, and then the two connecting strips can be locked by locking components, thereby achieving a stable connection.

[0011] Optionally, the inner side of the main shell plate is evenly provided with a plurality of vertical clamping plates for mounting the partition frame along the circumferential direction. The vertical clamping plates are integrally formed with the main shell plate. A first sealing groove is provided on the connecting strip, and a first sealing strip is fixedly installed in the first sealing groove.

[0012] By adopting the above technical solution, several vertical clamping plates are evenly arranged along the circumferential direction on the inner side of the main shell plate. When installation is required, one end of the partition frame can be stably clamped in the vertical clamping plates. The setting of the first sealing groove and the first sealing strip ensures a stable sealing connection when the two connecting strips are combined, thus avoiding leakage.

[0013] Optionally, a plurality of positioning slots corresponding to the partition frame are evenly provided on the outer side of the central shell, and a second sealing groove is provided at both ends of the central shell, in which a second sealing strip is fixedly installed.

[0015] Optionally, the locking component includes a concave buckle plate and an arc-shaped plate, wherein the arc-shaped plate is disposed at both ends of the concave buckle plate and is integrally formed with the concave buckle plate.

[0016] By adopting the above technical solution, the structure of the locking component is designed to ensure that it can be clamped and fixed to the connecting strip for locking during use by the concave buckle plate. At the same time, by setting arc-shaped plates at both ends of the concave buckle plate, the connection between the locking component and the arc-shaped shell is made more stable.

[0017] Optionally, the partition frame includes a main board and a T-shaped insert plate.

[0018] By adopting the above technical solution, the structure of the partition frame is designed to ensure that triangular clips and T-shaped inserts are respectively installed on both sides of the main board. This ensures that during installation, the triangular clips can be inserted into the positioning slots, and the T-shaped inserts can be engaged in the vertical clamps. Furthermore, by installing a sealing strip on the outer surface of the T-shaped inserts, the sealing performance of the partition frame installation is ensured, allowing the partition frame to better separate the space of the multi-space processing tower.

[0019] Optionally, the cover includes a cover plate, an annular mesh plate, and a sleeve. The annular mesh plate is disposed on the outer side of the cover plate and is fixedly connected to the cover plate. The sleeve is disposed on the lower end face of the cover plate and is integrally formed with the cover plate.

[0020] By adopting the above technical solution, the structure of the cover is designed to ensure that the sleeve is fixedly installed at the lower end of the cover plate.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses an advanced oxidation apparatus for leachate. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, an advanced leachate oxidation device includes a multi-space treatment tower, which consists of two interlocking shells 1. The two shells 1 are sealed and fixedly connected by a locking member 2. Each shell 1 includes a semi-annular base plate 11, an arc-shaped shell 12, and a central shell 13. The arc-shaped shell 12 is disposed on the outer side of the semi-annular base plate 11, and the central shell 13 is disposed on the inner side of the semi-annular base plate 11. The semi-annular base plate 11, the arc-shaped shell 12, and the central shell 13 are integrally formed. A detachable partition frame 3 is installed between the arc-shaped shell 12 and the central shell 13. A cover 4 is installed on the head of the central shell 13. The cover 4 is engaged and fixedly fixed to the central shell 13, and a positioning seat 5 is fixedly installed between the cover 4 and the arc-shaped shell 12. By designing the multi-space processing tower as two interlocking shells 1, it can be quickly installed by simply snapping them together when needed, and then secured by locking parts 2 at both ends. When not in use, the two shells can be disassembled, making it easier to clean their interiors individually. The shell 1 is designed with a semi-annular base plate 11, an arc-shaped shell 12, and a central shell 13. When in use, the semi-annular base plate 11 serves as the bottom of the oxidation equipment, facilitating stable placement. The arc-shaped shell 12 acts as the outer shell, and the central shell 13 as the inner shell. When the two shells 1 are snapped together, the two central shells 13 form a central cylindrical structure, and the two arc-shaped shells... The 12 components can be combined to form an integrated shell structure. Once the overall structure of the multi-space processing tower is fixed, several partition frames 3 can be installed to divide its internal space for use, ensuring that processing can be carried out in different spaces. At the same time, the partition frames 3 are designed to be installed between the arc-shaped shell 12 and the central shell 13, which is easy to flexibly plug and use as needed, ensuring greater flexibility in use. By installing a cover 4 at the head of the central shell 13, the two ends of the central shell 13 can be fixed together during use, which can further increase the overall stability of the multi-space processing tower. At the same time, by fixing a positioning bracket 5 between the cover 4 and the arc-shaped shell 12, it is convenient to install mixing equipment, etc., through the positioning bracket 5 during use.

[0035] Reference Figure 3 and Figure 4As shown, the arc-shaped shell 12 includes a main shell plate 121 and connecting strips 122. The connecting strips 122 are disposed at both ends of the main shell plate 121 and are integrally formed with the main shell plate 121. The structure of the arc-shaped shell 12 ensures that the connecting strips 122 can be disposed at both ends of the main shell plate 121 during use. This allows the connecting strips 122 to be interlocked together during use, and then easily locked by the locking member 2, thus achieving a stable connection. The inner surface of the main shell plate 121 is evenly provided with several vertical clamping plates 123 for mounting the partition frame 3 along the circumferential direction. The vertical clamping plates 123 are integrally formed with the main shell plate 121. A first sealing groove is formed on the connecting strip 122, and a first sealing strip 124 is fixedly installed in the first sealing groove. By evenly arranging several vertical clamping plates 123 along the circumferential direction on the inner side of the main shell plate 121, one end of the partition frame 3 can be stably engaged in the vertical clamping plates 123 when installation is required. The first sealing groove and the first sealing strip 124 ensure a stable sealing connection when the two connecting strips 122 are joined together, preventing leakage. Several positioning slots 131 corresponding to the partition frame 3 are evenly opened on the outer side of the central shell 13, and second sealing grooves are opened at both ends of the central shell 13, in which second sealing strips 132 are fixedly installed. By evenly opening several positioning slots 131 on the outer side of the central shell 13, one end of the vertical clamping plate 123 is engaged and fixed in the positioning slot 131 during installation. The second sealing groove and the second sealing strip 132 ensure a sealed connection when the two central shells 13 are engaged together.

[0036] Reference Figure 8 As shown, the locking component 2 includes a concave buckle plate 21 and an arc-shaped abutment plate 22. The arc-shaped abutment plate 22 is disposed at both ends of the concave buckle plate 21, and the arc-shaped abutment plate 22 is integrally formed with the concave buckle plate 21. The structural design of the locking component 2 ensures that it can be clamped and fixed to the connecting strip 122 for locking during use through the concave buckle plate 21. At the same time, by setting the arc-shaped abutment plates 22 at both ends of the concave buckle plate 21, the connection between the locking component 2 and the arc-shaped shell 12 is made more stable.

[0037] Reference Figure 5As shown, the partition frame 3 includes a main board 31 and a T-shaped insert plate 32. One side of the main board 31 has a triangular retaining strip 311 corresponding to the positioning slot 131. The T-shaped insert plate 32 is fixedly installed on the other side of the main board 31. A sealing strip 33 is also installed on the outer surface of the T-shaped insert plate 32, and the sealing strip 33 engages and secures with the T-shaped insert plate 32. By configuring the structure of the partition frame 3, triangular retaining strips 311 and T-shaped insert plates 32 are respectively provided on both sides of the main board 31. This ensures that during installation, the triangular retaining strips 311 can be inserted into the positioning slot 131, and the T-shaped insert plate 32 can be engaged and installed in the vertical clamping plate 123. Furthermore, the sealing strip 33 installed on the outer surface of the T-shaped insert plate 32 ensures the airtightness of the partition frame 3 installation, allowing the partition frame 3 to better separate spaces in the multi-space processing tower.

[0038] Reference Figure 6 As shown, the cover 4 includes a cover plate 41, an annular mesh plate 42, and a sleeve 43. The annular mesh plate 42 is disposed on the outer surface of the cover plate 41 and is fixedly connected to the cover plate 41. The sleeve 43 is disposed on the lower end surface of the cover plate 41 and is integrally formed with the cover plate 41. The structure of the cover 4 ensures that the sleeve 43 is fixedly installed at the lower end of the cover plate 41. During installation, the sleeve 43 can be fitted onto the heads of the two central shells 13, thereby ensuring a stable connection between the two central shells 13. At the same time, by fixing the annular mesh plate 42 on the outer surface of the cover plate 41, the annular mesh plate 42 can support the installation positioning bracket 5, ensuring that the positioning bracket 5 can be installed at the position on the annular mesh plate 42 according to the installation needs, and then the two are fixed together with bolts.

[0039] Reference Figure 7 As shown, the positioning bracket 5 includes a middle frame 51, a first side plate 52, and a second side plate 53. The first side plate 52 and the second side plate 53 are respectively fixedly installed on both sides of the middle frame 51, and the second side plate 53 is fixedly connected to the annular mesh plate 42 by bolts. The structural design of the positioning bracket 5 ensures that during use, the middle frame 51 can be stably installed on the upper surface of the arc-shaped shell 12 and the annular mesh through the first side plate 52 and the second side plate 53 at both ends. This allows for the installation of mixing equipment, etc., through the middle frame 51.

[0040] The implementation principle of the leachate advanced oxidation device in this application embodiment is as follows: In actual use, the two shells 1 are first fastened together, and then the locking parts 2 are used to lock and fix them on the connecting strips 122 on both sides of the shell 1. This ensures that the multi-space treatment tower is assembled. Then, according to the required area division, an appropriate number of partition frames 3 are selected and installed. The partition frames 3 are installed on different vertical clamps 123 according to the size requirements of each space. The partition frames 3 are locked and fixed between the vertical clamps 123 and the central shell 13. After all the partition frames 3 are installed, the cover 4 can be sleeved and fixed on the head of the central shell 13. Finally, the positioning seat 5 is fixedly installed directly above each space.
