Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of treatment devices, and in particular relates to a deep treatment device for ozone catalytic oxidation of coking wastewater. Background Technology
[0002] The ozone catalytic oxidation deep treatment device for coking wastewater is a device that uses ozone in the presence of a catalyst to deeply treat coking wastewater.
[0003] For example, Chinese patent CN217627982U discloses a deep treatment device for coking wastewater by ozone catalytic oxidation. This device enables ozone in the wastewater undergoing deep treatment by ozone catalytic oxidation to be heated at high temperature, thereby rapidly decomposing and attenuating, effectively avoiding the adverse environmental impact of ozone in wastewater.
[0004] In the ozone catalytic oxidation process, ozone reacts with pollutants in wastewater to generate oxidation products. At the same time, bubbles are generated, forming foam. The foam can block the reaction surface or reduce effective gas-liquid contact, thereby affecting the decomposition efficiency of ozone or other oxidants and reducing the removal rate of pollutants in wastewater. Utility Model Content

[0015] Preferably, the driving component is a motor, which is fixed to the reaction tower, and the output end of the motor is fixed to the first rod. The motor has the functions of self-locking, forward and reverse rotation, and speed control.
[0016] Preferably, the collection component includes:

[0020] Preferably, the collection assembly further includes a column, which is fixedly mounted on the plate. The column is capable of rotating the plate in the direction of rotation of the drive component when it contacts the discharge assembly, thereby increasing the horizontal height of the collection protrusion.
[0021] Preferably, the reaction tower has a discharge port, and part of the discharge assembly is installed inside the discharge port.
[0022] Preferably, the emission assembly includes:
[0023] A guide that lowers the horizontal height of the column upon contact with it;

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0039] In existing technologies, during the deep treatment of coking wastewater via ozone catalytic oxidation, it is observed that the residual rate of pollutants in the wastewater gradually increases with treatment time, the specific reasons for which are unknown. Further long-term observation and practice revealed that the scum generated during the treatment process can obstruct the reaction surface or reduce effective gas-liquid contact. To address this issue, such as... Figure 1 As shown, it includes: a reaction tower 100, an ozone generator 200, a drive assembly 300, a collection assembly 400, and an emission assembly 500. The drive assembly 300 drives the collection assembly 400 to rotate and collect the scum, which is then discharged using the emission assembly 500.
[0040] like Figure 1 As shown, the reaction tower 100 is existing technology (such as announcement number CN217627982U), and it is equipped with a cavity inside, which can perform deep treatment of coking wastewater by ozone catalytic oxidation.
[0041] Continue as Figure 1 As shown, the ozone generator 200 is existing technology (such as announcement number CN217627982U), which is capable of introducing ozone into the cavity;
[0042] Continue as Figure 1 As shown, the drive assembly 300 can apply rotational force to the cavity, thereby making the deep treatment of coking wastewater by ozone catalytic oxidation more uniform. Specifically, the drive assembly 300 includes: a drive element 310, a first rod 320, and several second rods 330.
[0043] The driving component 310 is a motor, which is fixed to the reaction tower 100. The output end of the motor is fixed to the first rod 320. The motor has self-locking, forward and reverse rotation, and speed control functions. The driving component 310 can drive the first rod 320 to rotate. The first rod 320 is a long, circular rod that passes through the reaction tower 100 and extends into the cavity. The first rod 320 can be driven to rotate by the driving component 310. Several second rods 330 are long, circular rods that are fixedly installed on the bottom of the outer wall of the first rod 320 (e.g., ...). Figure 1 (As shown in the lower position).
[0044] In use, the drive unit 310 is activated to rotate the first rod 320, which in turn drives several second rods 330 to rotate and stir the cavity, making the internal reactants come into contact more frequently and the reaction more uniform.
[0045] like Figure 1 As shown, the collecting component 400 and the driving component 300 are coupled together. The collecting component 400 is configured to rotate with the driving component 300 and collect the foam in the cavity. Specifically, the collecting component 400 includes: a third rod 410, a plate 420, and a collecting protrusion 440.
[0046] The third rod 410 is a long, circular rod, which is fixedly installed on the top of the outer wall of the first rod 320 (e.g., Figure 2 Above the second rod 330 shown); the plate 420 is rectangular and is rotatably mounted around the outer wall of the third rod 410 via bearings, allowing it to rotate about the third rod 410 as the center; the collecting protrusion 440 is rectangular and is fixedly mounted on the bottom of one side of the plate 420 (as shown above the second rod 330 ...). Figure 2 (At the bottom of the plate 420 shown), the collecting protrusion 440 faces the rotation direction of the drive member 310, thereby collecting the foam between the plate 420 and the collecting protrusion 440. It should be emphasized that the collecting protrusion 440 is flush with the liquid surface inside the cavity.
[0047] In operation, the first rod 320 drives the third rod 410 to rotate, which in turn drives the plate 420 to rotate. The plate 420 then drives the collecting protrusion 440 to rotate. During this process, the collecting protrusion 440 continuously contacts the foam above the liquid surface inside the cavity, collecting some of the foam between the plate 420 and the collecting protrusion 440 for storage, thus reducing the impact of the foam on the cavity's interior. It is important to note that when there is a large amount of foam or the wastewater density is high, the plate 420 and the collecting protrusion 440 will be pushed at a certain angle by the resistance generated when colliding with the foam. In this case, the amount of foam collected decreases, and the collision resistance between the plate 420, the collecting protrusion 440, and the foam is buffered, reducing the pressure of the collision resistance on the structure and improving its lifespan.
[0048] To enable more foam to be collected between plate 420 and collecting protrusion 440 in one go, a further solution is proposed, such as... Figure 2 As shown, an elastic element 450 is provided between the first rod 320 and the plate 420. The elastic element 450 enables the plate 420 to maintain an angle perpendicular to the liquid surface in the cavity when no external force is applied. The elastic element 450 is a torsion spring, and its two ends are fixed to the plate 420 and the first rod 320, respectively. The elastic force of the torsion spring reduces the impact of collision resistance between the plate 420, the collecting protrusion 440, and the foam, so that more foam can be collected between the plate 420 and the collecting protrusion 440, thus accelerating the foam treatment rate. Under this scheme, the density of the wastewater should be low to avoid the plate 420 and the collecting protrusion 440 being subjected to the resistance of the wastewater, which would cause the operating load of the device to be too large.
[0049] Further solutions, such as […], are being developed to address the emission of droplets and ozone. Figure 1 As shown, the reaction tower 100 has a discharge port 110 (rectangular). Part of the structure of the discharge assembly 500 is installed in the discharge port 110. The discharge assembly 500 and the collection assembly 400 are coupled. The discharge assembly 500 is configured to discharge scum when the collection assembly 400 contacts the discharge assembly 500. The collection assembly 400 also includes a column 430, which is a long, circular rod. The column 430 is fixedly installed on the plate 420 near the discharge assembly 500. When the column 430 contacts the discharge assembly 500, it causes the plate 420 to rotate in the direction of rotation of the drive member 310, thereby increasing the horizontal height of the collection protrusion 440 (e.g., ...). Figure 3 The state shown causes the height of the foam and the discharge port 110 to overlap and the foam to be thrown into the discharge assembly 500 by the inertia of rotation. Specifically, the discharge assembly 500 includes: guide 510 and discharge component 520.
[0050] The guide 510 is an inclined rod-shaped component, fixedly installed on the inner wall of the reaction tower 100. The horizontal height of the guide 510 gradually decreases, allowing the column 430 to contact the guide 510. Upon contact with the guide 510, the guide 510 lowers the horizontal height of the column 430. At this time, the column 430 drives the plate 420 to rotate in the direction of rotation of the drive 310, and the horizontal height of the collecting protrusion 440 is reduced as follows. Figure 3 The material is raised to the height of the overlapping discharge port 110. At this time, the scum between the plate 420 and the collecting protrusion 440 is thrown towards the discharge component 520 by the centrifugal force generated by the rotation. The discharge component 520 is a U-shaped plate that is fixedly installed in the discharge port 110. It can discharge scum and ozone to facilitate subsequent treatment (the treatment method is the prior art, such as the announcement number CN217627982U).
[0051] It should be emphasized that the removal of scum and ozone can maintain the efficiency of the reaction inside the reaction tower (100) cavity and reduce the impact caused by scum.
