Description

[0035] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, a BPDA wastewater recovery and treatment device includes a closed processor 1 and also includes:

[0036] The closed partitions 101 are horizontally symmetrically arranged on the upper and lower sides of the closed processor 1, and the closed partitions 101 are used to separate the interior of the closed processor 1 from top to bottom into a processing input chamber 103, a heating and conveying chamber 2, and a processing output chamber 106;

[0037] The connecting tubes 102 are evenly arranged vertically inside the heating and conveying chamber 2, and the upper and lower ends of the connecting tubes 102 are respectively connected to the processing input chamber 103 and the processing output chamber 106;

[0038] Loading and unloading openings 302, multiple loading and unloading openings 302 are evenly arranged on the top surface of the closed processor 1, and the loading and unloading openings 302 are arranged one-to-one with the communicating tubes 102;

[0041] In this embodiment, the device includes a closed processor 1, the interior of which is divided into three independent and sealed areas by two horizontally symmetrical closed partitions 101, namely a processing input bin 103 at the upper part, a heating and conveying bin 2 at the middle part, and a processing output bin 106 at the lower part. The processing input bin 103 and the processing output bin 106 are respectively connected with a processing input pipe 104 and a processing output pipe 105. The heating and conveying bin 2 is provided with a plurality of vertically evenly arranged connecting tubes 102. The upper ends of these connecting tubes 102 are connected to the processing input bin 103, and the lower ends are connected to the processing output bin 106. The top of the closed processor 1 is provided with a plurality of loading and unloading openings 302, which correspond one to one with the connecting tubes 102 and are used to insert the absorbent carrier tube 5 into the corresponding connecting tube 102. The absorbent carrier tube 5 is a tubular structure that can be slidably nested and installed in the connecting tube 102. A plurality of connecting openings 501 are provided on its side wall to allow the wastewater to pass through and fully contact the absorbent. The absorbent carrier tube 5 is filled with absorbent particles for adsorbing and recovering organic matter in the BPDA production wastewater. The top of the absorbent carrier tube 5 is provided with a maintenance opening 502, which is connected to the absorbent carrier tube 5 by a detachable sealing member. The top cover 6 is closed for sealing, and the top cover 6 and the maintenance opening 502 are installed and removed by means of a threaded connection, which is convenient for quick opening to replace or replenish absorbent particles. At the same time, the outer dimensions of the top cover 6 are adapted to the loading and unloading opening 302. When the absorbent carrier tube 5 is taken out from the loading and unloading opening 302, the top cover 6 can also be used as a blocking member to be embedded in the loading and unloading opening 302 to ensure the sealing performance of the entire treatment equipment. When the absorbent is absorbed or needs to be replaced, the entire absorbent carrier tube 5 can be slid upward along the loading and unloading opening 302 through the top cover 6, thereby realizing the overall disassembly of the absorbent carrier tube 5. Subsequently, The closed top cover 6 is opened to pour out the expired absorbent particles, and new absorbent particles are refilled, and then the absorbent carrier tube 5 is reinserted into its original position and sealed to complete the rapid replacement and maintenance of the absorbent. The device provides a loading and unloading opening 302 on the top of the processing equipment, and cooperates with the slidable and detachable absorbent carrier tube 5 structure, so that the absorbent carrier tube 5 can be pulled out as a whole from the top, which greatly simplifies the absorbent replacement process and improves the equipment maintenance efficiency. In addition, the detachable design of the absorbent carrier tube 5 can complete the absorbent replacement without disassembling the entire processing equipment, avoiding long-term system shutdown and improving the continuity and safety of the device operation.

[0042] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, preferably, a heat carrier input pipe 203 is provided on the top of the heating and conveying bin 2 of the device, and a heat carrier output pipe 204 is provided on the bottom, which is used to introduce the heat carrier provided by the external heat source, such as hot water, into the heating and conveying bin 2 to increase the internal temperature and further improve the absorption and processing efficiency. A plurality of folding guide plates 201 are arranged uniformly and parallelly in the vertical direction inside the heating and conveying bin 2, so that the heat carrier flows through the space between each folding guide plate 201 in the set direction in sequence in the heating and conveying bin 2, and the adjacent folding guide plates 201 are arranged in parallel. A connecting conveying port 202 is provided in between, and the connecting conveying port 202 is located on the opposite side of the bending guide plate 201, ensuring that the heat carrier can pass through each layer of the guide area in sequence to achieve sufficient heat exchange. Through the above-mentioned structural design, after the heat carrier enters the heating and conveying bin 2 from the heat carrier input pipe 203, it flows in a "Z" shape under the action of multiple bending guide plates 201, extending its residence time in the heating and conveying bin 2 and improving the heat exchange efficiency. At the same time, this flow mode also ensures the uniformity of the overall temperature distribution of the heating and conveying bin 2.

[0043] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, preferably, a central traction rod 601 is vertically connected to the bottom center of the closed top cover 6 of the device, and a closed bottom plate 602 is connected to the bottom of the central traction rod 601. The closed bottom plate 602 is nested and slidably arranged on the inner side of the absorbent carrier tube 5, so that when the closed top cover 6 is disassembled, the closed bottom plate 602 can be pulled by the central traction rod 601 to move upward along the absorbent carrier tube 5 synchronously to push out the absorbent particles inside the absorbent carrier tube 5, thereby facilitating the unloading and reloading of the absorbent particles, and significantly improving the operational convenience and efficiency of the absorbent loading and unloading.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, preferably, the top end of the device connecting array tube 102 is connected to the corresponding loading and unloading opening 302 through an adjusting conveying pipe 3, and the upper and lower ends of the adjusting conveying pipe 3 are respectively connected between the loading and unloading opening 302 and the connecting array tube 102, which is used as a transition channel for the flow of wastewater and provides a guiding space for the insertion of the absorbent carrier tube 5.

A corresponding setting is provided, and by controlling the rotation angle of the rotating sealing cylinder 4, the relative position relationship between the delivery opening 301 and the connecting opening 401 can be adjusted. When the two coincide, the wastewater can enter the connecting tube 102 through the opening. When the two are staggered and closed, the regulating delivery pipe 3 is sealed and isolated, thereby blocking the wastewater from flowing into the corresponding connecting tube 102 and the absorbent carrier tube 5, so that the corresponding regulating delivery pipe 3 and the connecting tube 102 can be opened or closed as needed, so that when the absorbent carrier tube 5 is replaced, the corresponding flow channel is selectively closed to avoid the entire reaction system from being shut down due to the replacement process, thereby improving the flexibility and safety of the equipment operation, and the number of absorbent carrier tubes 5 participating in the reaction can be flexibly adjusted according to the actual working conditions to adapt to the wastewater treatment needs under different loads, thereby improving the equipment utilization rate and energy efficiency.

[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, preferably, a rotation locking groove 303 is provided around the top edge of the loading and unloading opening 302 of the device.

When the absorbent carrier tube 5 is fully inserted into the communicating array tube 102, the chimeric linkage block 503 is synchronously inserted into the chimeric linkage groove 403 of the rotating connecting ring 402. In the process of rotating the absorbent carrier tube 5, a mechanical connection that can transmit torque is formed. When the operator rotates the absorbent carrier tube 5, the operator can drive the interlocking linkage block 503 to rotate through the absorbent carrier tube 5, thereby causing the interlocking linkage block 503 to push the rotating connection ring 402 and the rotating closed cylinder 4 fixedly connected thereto to rotate synchronously. The rotation of the rotating closed cylinder 4 will change the relative position relationship between the connecting opening 401 on its side wall and the delivery opening 301 on the regulating delivery pipe 3, thereby realizing the opening or closing control of the wastewater flow path, and cooperating with the locking structure of the absorbent carrier tube 5, the absorbent carrier tube 5 can be locked and unlocked while opening and closing the wastewater flow path, making the overall operation more convenient and safer.

The plurality of closed processors 1 are respectively circulated to input and transport wastewater, organic solvent and deionized water through the treatment input pipe 104 and the treatment output pipe 105, so that after the absorbent carrier tube 5 completes the absorption treatment of the wastewater in the closed processor 1 for transporting wastewater, it can be taken out as a whole and inserted into the closed processor 1 for transporting the organic solvent. After the transported organic solvent is fully in contact with the absorbent inside the absorbent carrier tube 5, the adsorbent is eluted, and the enriched high-concentration organic matter is released for recycling. Then the absorbent carrier tube 5 is taken out as a whole and inserted into the closed processor 1 for transporting the deionized water. In the closed processor 1 for ionized water, after the absorbent inside the absorbent carrier tube 5 is cleaned by the transported deionized water, the absorbent carrier tube 5 is reinserted into the closed processor 1 for transporting and treating wastewater, thereby realizing the cyclic treatment work of adsorption, desorption and cleaning and resetting, so as to realize the recovery and treatment work of organic matter in the wastewater, and the central rotating shaft 9 is interconnected with the lifting guide frame 7. A rotation adjustment motor 901 is arranged in the middle of the central rotating shaft 9. The rotation adjustment motor 901 can drive the central rotating shaft 9 to rotate, and then drive the lifting guide frame 7 to rotate as a whole, so that the positioning and loading and unloading frame 8 on the lifting guide frame 7 can realize the cyclic loading and unloading of the absorbent carrier tube 5 between multiple closed processors 1 after removing the absorbent carrier tube 5, so as to realize the cyclic treatment work of adsorption, desorption and cleaning and resetting, and the overall treatment efficiency is higher.

[0050] The BPDA wastewater recovery and treatment device provided by the present invention slides the entire absorbent carrier tube 5 upward along the loading and unloading opening 302 through the closed top cover 6, thereby realizing the overall disassembly of the absorbent carrier tube 5. The closed top cover 6 can be opened to pour out the expired absorbent particles and refilled with new absorbent particles, and then the absorbent carrier tube 5 is reinserted into its original position and sealed to complete the rapid replacement and maintenance of the absorbent. By setting the loading and unloading opening 302 at the top of the treatment equipment and cooperating with the slidable and detachable absorbent carrier tube 5 structure, the absorbent carrier tube 5 can be pulled out as a whole from the top, which greatly simplifies the absorbent replacement process and improves the equipment maintenance efficiency. In addition, the detachable design of the absorbent carrier tube 5 can complete the absorbent replacement without disassembling the entire treatment equipment, avoiding long-term system shutdown and improving the continuity and safety of the device operation.
