Description

Technical Field

[0001] This invention relates to the field of semi-coke wastewater treatment technology, specifically to a semi-coke wastewater treatment and phenol removal device. Background Technology

[0002] Semi-coke wastewater is a high-concentration organic wastewater generated during the semi-coke production process. It contains a large amount of phenolic compounds (especially ternary and higher phenols), tar, suspended solids (SS), and water-insoluble oily substances. If not treated properly, it will cause serious pollution to the water environment. Therefore, efficient phenol removal and pollutant removal are the core requirements for semi-coke wastewater treatment and a key link to ensure the stable operation of subsequent biological treatment (such as A / O system).

[0003] Currently, the mainstream technology for treating semi-coke wastewater in China is air flotation, with dissolved air flotation (DAF) being the most widely used. This method involves dissolving air in water to form dissolved air water, which is then released under reduced pressure to generate bubbles. These bubbles adsorb suspended solids (SS) and oily substances in the wastewater, achieving separation. However, this technology has significant drawbacks: during the contact between air and wastewater, phenolic compounds in the wastewater are oxidized to quinones. Subsequent A / O systems cannot degrade quinones, leading to effluent that fails to meet standards. Furthermore, it affects the activity of microorganisms in the biological system, reducing overall treatment efficiency.

[0004] Another commonly used technology is nitrogen flotation, which separates pollutants using nitrogen bubbles. While this avoids the oxidation of phenols, it suffers from poor separation efficiency and weak adaptability to raw water quality. The quality of semi-coke wastewater fluctuates greatly. Influenced by raw materials and process parameters in semi-coke production, the concentration of suspended solids (SS), phenol content, and oil content in the wastewater often change drastically. Under these conditions, the separation capacity of nitrogen flotation decreases significantly, failing to stably remove ternary and higher-order phenols and tar, resulting in unstable treatment effects and difficulty meeting the needs of continuous industrial treatment. Based on the shortcomings of existing technologies, there is an urgent need to develop a semi-coke wastewater treatment and phenol removal device that can efficiently separate ternary and higher-order phenols from tar while preventing the oxidation of phenols to quinones.

[0005] Therefore, a phenol removal device for semi-coke wastewater treatment was proposed to solve the above problems. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example 1, please refer to Figures 1 to 9 As shown: To address the problems mentioned in the technical solutions, this application provides a phenol removal device for treating semi-coke wastewater, including a flotation 1. A ladder 14 is provided on one side of the flotation 1. A steam-water mixer 11 is connected to the flotation 1 via a pipeline. A dissolved air pump 12 is connected to the bottom of the steam-water mixer 11 via a pipeline. A pipeline mixer 13 is installed on the dissolved air pump 12. The phenol removal device for treating semi-coke wastewater also includes an automatic directional movement mechanism 2 and an automatic switching mechanism 3. The automatic directional movement mechanism 2 is located above the flotation 1, and the automatic switching mechanism 3 is located in the middle of the flotation 1. In this system, dissolved air pump 12 mixes wastewater, carbon dioxide gas, and nitrogen gas in a certain proportion within pipeline mixer 13, and then pumps the mixture into steam-water mixer 11. Under the pressure of 0.45 MPa-0.55 MPa within steam-water mixer 11, the solubility of carbon dioxide gas increases, allowing it to dissolve better in the wastewater and react with phenolic pollutants. Nitrogen gas also exhibits good solubility at this pressure, coupling with carbon dioxide and playing a crucial role in generating microbubbles after subsequent pressure release. The internal structure of steam-water mixer 11 is detailed in the CAD drawing. The steam-water mixture enters from the middle of steam-water mixer 11, flows tangentially through the internal conical guide tube, and exits from a 50mm × 50mm hole at the bottom of the cone. The steam-water mixture forms a swirling flow within the conical guide tube, increasing the reaction time while reducing the equipment volume. After the reaction is complete, the steam-water mixture flows out from the top of steam-water mixer 11 into flotation machine 1. A pressure gauge is installed on the top of steam-water mixer 11 for monitoring and adjustment.

[0026] The effluent from the gas-water mixer 11 flows by gravity into the gas release zone of the flotation machine 1, where it is released through a gas release device. Carbon dioxide and nitrogen gases are released through a dedicated release head, forming microbubbles that float suspended solids and water-insoluble light oily substances to the surface. These are then scraped to the collection trough by a scraper trolley. After passing through the release zone, the wastewater flows by gravity into the sedimentation zone. The purpose of the sedimentation zone is to settle the heavier, water-insoluble oily substances to the bottom. A density meter is installed at the bottom of the sedimentation tank. When the density reaches 1.07, the bottom sludge discharge valve automatically opens; when the density is below 1.01, the bottom sludge discharge valve automatically closes. After passing through the sedimentation zone, the wastewater flows by gravity into the drainage trough for discharge.

[0027] The bottom of the flotation machine 1 is symmetrically equipped with sedimentation zones. The purpose of the sedimentation zones is to settle heavy, water-insoluble oily substances at the bottom. A density meter is installed at the bottom of the sedimentation tank. When the density reaches 1.07, the bottom slag discharge valve automatically opens; when the density is lower than 1.01, the bottom slag discharge valve automatically closes. After passing through the sedimentation zone, the wastewater flows by gravity into the drainage trough for discharge.

[0028] Specifically, such as Figure 4 and Figure 5As shown, the track toothed plate 21 has symmetrical gear slots in the middle. The two ends of the track toothed plate 21 are fixedly installed on the inner wall of the upper surface of the flotation 1. A slide table 22 is slidably installed on the upper surface of the track toothed plate 21. A main drive gear 23 is rotatably installed in the middle of the slide table 22. A driven gear 26 meshes with the tooth surface of the main drive gear 23. The driven gear 26 is symmetrically rotatably installed in the slide table 22. A meshing tooth 25 meshes with the tooth surface of the driven gear 26 away from the main drive gear 23. A bearing is installed in the middle of the lower surface of the meshing tooth 25. Guide slots are symmetrically opened at the bottom of the slide table 22, and the bearing is slidably installed in the guide slot of the slide table 22 in the middle of the outer surface of the bearing. A pulley 24 is fixedly installed in the middle of the upper surface of the meshing tooth 25. A transmission belt 27 is driven on the pulley 24. A guide wheel is installed on the inner wall of one side of the slide table 22. The transmission belt 27 is driven on the guide wheel in the middle. A sealing plate is installed on the upper surface of the track tooth plate 21, and a drive motor is installed above the sealing plate. The drive shaft of the drive motor is fixedly installed in the middle of the main drive gear 23. The rotation of the drive motor can drive the main drive gear 23 to rotate, and at the same time drive the meshing driven gear 26 to drive the meshing teeth 25 to start rotating in the same direction as the main drive gear 23. The rotation of the meshing teeth 25 can drive the pulley 24 to rotate symmetrically and synchronously, which provides power support for driving the automatic switching mechanism 3 to automatically adjust the movement direction of the slide table 22.

[0029] Specifically, such as Figure 7 and Figure 9 As shown, the upper surface of the middle part of the dynamic switching gear 31 is fixedly mounted on the meshing gear 25. The tooth surface of the dynamic switching gear 31 meshes in the gear groove opened in the track tooth plate 21. The lower surface of the middle part of the dynamic switching gear 31 is rotatably mounted with a directional adjustment plate 33. The middle part of the directional adjustment plate 33 is rotatably mounted with a slide plate 32. The slide plate 32 is slidably mounted on the lower surface of the track tooth plate 21. A pressure column 34 is fixedly mounted on the lower surface of the directional adjustment plate 33 near the dynamic switching gear 31. A directional locking column head 35 is symmetrically slidably mounted on the upper surface of the slide plate 32. A compression spring 36 is sleeved on the outer surface of the directional locking column head 35. One end of the compression spring 36 is fixedly mounted on the directional locking column head 35. The other end of the compression spring 36 is fixedly mounted with a pressure plate. A pressure groove is opened in the middle part of the directional locking column head 35 near the directional adjustment plate 33. The pressure column 34 is slidably mounted in the pressure groove. The dynamic switching gear 31 and the compression spring 36 are symmetrically arranged at both ends of the slide plate 32, and the directional locking pins 35 are connected by a universal connecting rod slidably mounted on the directional locking pins 35.

[0030] A semi-circular extrusion plate 37 is fixedly installed in the middle of the slide plate 32. Semi-circular grooves are symmetrically opened on both sides of the semi-circular extrusion plate 37. A connecting hole is opened in the middle of the semi-circular groove of the semi-circular extrusion plate 37. The directional locking pins 35 set on both sides of the semi-circular extrusion plate 37 are movably connected through the connecting hole by a connector. A telescopic plate 38 is installed on the lower surface of the slide plate 32. A floating scraper 39 is fixedly installed at the end of the telescopic plate 38 away from the slide plate 32. When one end of the directional adjustment plate 33 moves to the end of the track tooth plate 21 and is pressed against the inclined surface of the triangular pressing block 301, as... Figure 6 As shown, when the directional adjustment plate 33 at one end is pressed against the inclined surface of the triangular extrusion block 301, it will cause the directional adjustment plate 33 to start swinging. Since the middle part of the directional adjustment plate 33 is installed as a lever, the swinging of one end of the directional adjustment plate 33 will cause the dynamic switching gear 31 at the other end of the directional adjustment plate 33 to start sliding in the guide groove of the slide table 22. At this time, as shown... Figure 7 As shown, the dynamic switching gear 31 will start to disengage from the upper tooth surface of the track tooth plate 21 due to the swing of the directional adjustment plate 33, and at the same time engage with the lower tooth surface of the track tooth plate 21. At this time, the pressure column 34 will squeeze the compression spring 36. At the same time, the mutual squeezing of the directional locking column head 35 and the semi-circular extrusion plate 37 will drive the directional locking column head 35 to slide to the upper end of the semi-circular extrusion plate 37. At the same time, the compression spring 36 will start to elastically extend again to achieve self-locking. Thus, the movement direction of the slide table 22 can be switched by squeezing through the directional adjustment plate 33. At the same time, by installing a rotatable and extendable floating scraper 39 under the slide plate 32, suspended objects can be cleaned and the height of the floating scraper 39 can be customized according to the liquid level.

[0031] The bottom of flotation unit 1 is symmetrically provided with conical backflow tubes, which are used to form swirls in the mixture; Example 2: This solution is applicable to the wastewater treatment workshop of semi-coke production enterprises.

The steam-water mixer 11 is connected to the upper part of the flotation machine 1 through a pipeline, and the bottom is connected to the dissolved air pump 12 through a pipeline. The pipeline mixer 13 is installed at the input end of the dissolved air pump 12, and interfaces for wastewater, carbon dioxide and nitrogen are reserved.

[0036] II. Operating parameter settings; Mixing ratio adjustment: The mixing ratio of wastewater, carbon dioxide and nitrogen is set through the pipeline mixer 13, wherein the total proportion of gas is 5%-8% of the wastewater volume, and the volume ratio of carbon dioxide to nitrogen is 3:2.

[0037] Pressure parameter setting: Adjust the output pressure of dissolved air pump 12 to stabilize the working pressure inside the steam-water mixer 11 at 0.45-0.55MPa. The pressure is monitored in real time by a pressure gauge, and an automatic alarm is triggered when the deviation exceeds ±0.02MPa.

[0038] Sludge discharge parameter settings: Set the densitometer trigger threshold; when the sludge density in the sedimentation zone reaches 1.07 g / cm³. 3 When the density is below 1.01 g / cm³, the bottom slag discharge valve will automatically open. 3 When the slag discharge valve closes automatically, the slag discharge time is controlled to be 3-5 minutes each time.

[0039] Slag scraping mechanism parameters: Set the drive motor speed so that the slide table 22 moves at a speed of 0.5m / min. The automatic switching mechanism 3 is triggered by the triangular extrusion block 301 to realize the reciprocating movement of the slide table 22. The slag scraping frequency is once every 30 minutes.

[0040] III. Pretreatment and Feeding Preparation; Raw water pretreatment: The semi-coke wastewater is filtered through a screen to remove large particulate impurities and then enters an equalization tank for homogenization and flow equalization. The pH value of the raw water is controlled between 6.5 and 8.5, and the water temperature is maintained between 20 and 35℃.

[0041] Medium preparation: Carbon dioxide gas purity ≥99.5%, nitrogen gas purity ≥99.8%. Check cylinder pressure beforehand to ensure stable gas supply.

[0043] Load start-up: First, introduce carbon dioxide and nitrogen. After the pressure inside the gas-water mixer 11 reaches the set value, introduce the pretreated semi-coke wastewater to ensure that the gas and liquid are fully mixed.

[0044] Operation monitoring: Observe the liquid level in the flotation machine 1 in real time and keep the liquid level 20-30cm from the top; monitor the scum scraping effect. If there is too much scum residue, the scum scraping frequency can be increased appropriately; take a sample through the outlet of the air-water mixer 11 to detect the microbubble particle size and ensure that the particle size is ≤50μm.

[0045] Subsequent treatment: The treated wastewater flows by gravity into the subsequent A / O treatment system, and the scum in the sludge collection tank is regularly transported to the hazardous waste treatment station for harmless disposal.
