Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a treatment system for phenol-containing wastewater from a two-stage gasifier. Background Technology

[0002] Existing treatment systems for phenol-containing wastewater from two-stage gasifiers are extremely complex, requiring numerous functional devices, resulting in high configuration and maintenance costs for enterprises. They also easily lead to the waste of some phases and heat / cold energy. A new treatment system for phenol-containing wastewater from a two-stage gasifier, as described in application number 2019112276354, includes a phenol water tank. This system is simple and has low configuration costs, and the generated heat / cold energy and gas / vapor are returned to the gas production process, improving utilization efficiency.

[0003] Although this processing system solves the problems of existing technologies, it still has certain shortcomings:

[0004] 1) This system achieves phase separation by natural sedimentation inside the phenol water tank. However, natural sedimentation is inefficient, time-consuming, and does not readily release phenol-containing gas, thus affecting the recovery and treatment of phenol-containing phases.

[0005] 2) The phenol water tank is equipped with a phenol water pump and a mud pump. On the one hand, the fixed pump body affects the precipitation of the phase and easily causes the adhesion of the sediment to the bottom, which affects the final discharge. On the other hand, the fixed position of the phenol water pump and the different impurity content in the wastewater result in different sedimentation heights of the sediment, which makes it impossible to effectively discharge the clear liquid completely, thereby reducing the overall treatment effect of phenol-containing wastewater.

[0006] Therefore, it is necessary to address the problems that still exist in existing technologies. Summary of the Invention

[0016] Beneficial effects

[0017] This invention provides a treatment system for phenol-containing wastewater from a two-stage gasifier. Compared with existing technologies, it has the following advantages:

[0018] (1) By setting up a material handling mechanism, the lifting rod first drives the filter plate to rise and fall, and accelerates the sedimentation speed through pressure filtration, thereby improving the wastewater treatment efficiency. At the same time, the sedimentation surface is flattened to facilitate the complete discharge of the clear liquid. Secondly, the rotating motor drives the rotating plate to rotate, so that the clear liquid follows the movement, so as to release the phenol-containing gas, thereby improving the overall wastewater treatment effect and efficiency.

[0019] (2) By setting up the pump liquid assembly, the position of the suction hood and impeller can be easily adjusted by the extension and retraction of the bellows and telescopic rod. By fixing the suction hood and filter plate, the suction hood can change with the change of sedimentation height, so that it can always be at the bottom of the clear liquid layer, so that the clear liquid can be completely discharged.

[0020] (3) By setting up a discharge assembly, the hood can collect the sediment for easy discharge. At the same time, the combination of baffle and square tube can control the movement of the sediment to facilitate the separation and discharge of the clear liquid. The setting of the support plate facilitates the transport of the sediment and can further separate the clear liquid contained in the sediment, thereby improving the wastewater treatment effect.

[0021] (4) By setting up a drive unit, the drive motor is used to drive the rotating gear and the drive gear, and the rotating gear meshes with each other, so that the ball screws on the three sides drive the slide rod to reciprocate, thereby causing the upper slide rod to push the support plate, causing it to vibrate with the sediment, so as to separate the phases. The slide rods on the left and right sides drive the support plate to reciprocate through the support rod, which can transport the processed sediment for discharge.

[0022] (5) By setting up a material control unit, the amount of sediment can be controlled by utilizing the space between adjacent partitions, thereby improving the efficiency and effect of reprocessing the sediment. At the same time, the combination of worm gear and worm can control the interval of material feeding, so as to feed according to the actual processing situation, and facilitate the orderly pumping of sediment to avoid accumulation and blockage.

[0042] Example 6: This example combines Examples 1 to 5. First, pressure filtration improves the separation efficiency and facilitates the pumping of the clarified liquid. Second, vibration filtration facilitates the further separation of precipitate and clarified liquid and the convenient transfer and discharge of precipitate, thereby improving the effect and efficiency of wastewater treatment.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] During operation, phenol-containing wastewater from the secondary gasifier is first added to the sedimentation tank 1 through the inlet pipe. Then, the output end of the lifting rod 8 extends, driving the filter plate 2 into the wastewater. This allows the filter plate 2 to press and filter the wastewater, accelerating the separation and sedimentation of substances such as tar. Next, the rotating motor 11 drives the rotating plate 9 to rotate inside the annular groove 10 via the lifting rod 8, causing the liquid to follow the movement. Centrifugal force ensures the uniform distribution of substances such as tar and the rapid precipitation of phenol-containing gas. The phenol-containing gas then enters the external photo-oxidizer through the exhaust pipe for decomposition. Subsequently, the output end of the lifting rod 8 extends again, allowing the filter plate 2 to... The wastewater continues to be filtered, and substances such as tar are completely precipitated and compacted, thus completely separating the clear liquid. Simultaneously, during the movement of filter plate 2, the corrugated pipe 32 is stretched by deformation, and the output end of the telescopic rod 37 extends, causing the impeller 35 and suction hood 33 to move with filter plate 2. After the tar and other precipitates are compacted, the pump motor 36 drives the impeller 35 to rotate via the telescopic rod 37, causing the clear liquid to pass through the suction hood 33, corrugated pipe 32, and drain pipe 31, pumping it into the external phenol water evaporator for further treatment. After the clear liquid is completely extracted, the output end of the push-pull rod 49 retracts, causing the two side baffles 48 to rotate and open, allowing the precipitated material to pass through. The material flow guide hood 41 converges and guides the material into the square tube 42, positioned between adjacent baffles 472. Then, the control motor 475, through the transmission of worm gear 473 and worm 474, causes the rotating shaft 471 to drive the baffles 472 to rotate. This allows the sediment to pass through the guide side of the baffle 48 and enter the strip tube 43 via the material trough 44, positioned above the support plate 45. Next, the drive motor 466 rotates, and through the meshing of the drive gear 467, rotating gear 463, and the rotating gear 463, the three ball screws 462 rotate synchronously. The ball screws 462 then drive the three sliding rods 464 to reciprocate axially. During the movement, the upper slide bar 464 collidees with the support plate 45, causing the support plate 45 and the sediment to vibrate, thereby dispersing the sediment and detaching it from the support plate 45. Subsequently, the slide bars 464 on both sides move back and forth on the support plate 45 via the support rod 465, thereby conveying the sediment through the support plate 45. During the conveying process, clear liquid is continuously separated and collected at the bottom of the strip tube 43. It is then discharged to the phenol water evaporator inside the outside through the lower discharge pipe 412 for treatment. At the same time, the sediment is guided by the inclined plate 411 on one side and discharged through the aforementioned discharge pipe 412 to the outside tar storage tank for storage.

[0045] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
