Description

Technical Field

[0001] This invention belongs to the field of industrial wastewater treatment technology, specifically a circulating oxidation treatment device for industrial wastewater. Background Technology

[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, and finished products lost with the wastewater, as well as pollutants generated during production. One of the treatment processes for industrial wastewater is cyclic oxidation treatment, which leverages the chain effect of oxidation reactions and the synergistic effect of catalysts, combined with reflux design in the process flow, to achieve high efficiency and economy in wastewater treatment.

[0003] Some existing solid catalysts used for wastewater oxidation are typically fixed inside the reactor. The fixed position of the solid catalyst limits the range of contact and reaction with the wastewater. Furthermore, impurities such as precipitates are generated during the wastewater oxidation process and remain in the reactor, easily encapsulating the solid catalyst. This affects the oxidation reaction between the solid catalyst and the wastewater and can reduce the effective treatment depth of the wastewater, thus lowering the wastewater oxidation efficiency.

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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. Example 1

[0020] Please see Figure 1 - Figure 6 This application provides a circulating oxidation treatment device for industrial wastewater, comprising: An oxidation reaction tank 100 is provided with a top frame 300 on top of the oxidation reaction tank 100; The catalytic depreciation mechanism 200 installed on the top of the top frame 300 allows the catalytic ring 204 to swing up and down in the oxidation reaction tank 100, expanding the contact range between the solid catalyst and the wastewater, improving the efficiency of wastewater oxidation treatment. At the same time, the precipitated products of the oxidation treatment can be collected and treated in a timely manner, preventing the precipitated products from remaining in the tank and encapsulating the solid catalyst, reducing adverse factors on wastewater oxidation treatment, and increasing the stability of wastewater oxidation treatment. The catalytic depreciation mechanism 200 includes a catalytic ring 204 extending into the oxidation reaction tank 100 to agitate the wastewater, a swing rod component 201 driving the catalytic ring 204 to swing, multiple depreciation components 206 uniformly installed on the top of the catalytic ring 204 for collecting wastewater precipitates, and a driving component 202 driving the swing rod component 201 to swing.

[0021] In this embodiment, preferably, the driving component 202 includes a driving motor, two sprockets and a transmission chain. A frame 203 is provided on the upper surface of the top frame 300. The driving motor is mounted on the frame 203. The output shaft of the driving motor is connected to one of the sprockets, while the other sprocket is mounted on the frame 203 and connected to the connecting shaft 2015. A transmission chain is provided between the two sprockets.

[0022] In this embodiment, preferably, the rocker arm component 201 is rotatable left and right, driving the catalyst ring 204 to swing back and forth. The rocker arm component 201 includes: A connecting rod 2014 is rotatably connected to the top frame 300, and an upper sliding plate 2011 is provided on the top of the connecting rod 2014; A connecting shaft 2015 is connected to the drive component 202, and the front end of the connecting shaft 2015 is connected to the large-diameter end of the cam 2012. The slider 2013 is installed at the small diameter end of the cam 2012. The surface of the upper sliding plate 2011 is provided with an oblong hole that slides with the slider 2013, so that as the cam 2012 rotates, the slider 2013 slides in the oblong hole, thereby causing the upper sliding plate 2011 to swing.

[0023] In this embodiment, preferably, a rotating member 205 is installed between the catalytic ring 204 and the rocker arm member 201. The rotating member 205 drives the catalytic ring 204 to rotate. The catalytic ring 204 includes: The base 2051 is sleeved on the lower end of the connecting rod 2014. The base 2051 is rotatably connected to the top frame 300. The top frame 300 is equipped with a cross frame 301. The cross frame 301 can support the base 2051 without affecting the rotation of the base 2051. A rotary motor 2052 is installed at the bottom of the base 2051. The lower surface of the base 2051 may be provided with a housing to protect the rotary motor 2052, similar to the structure of the motor housing 2085, which is not shown in the attached drawing. A circular plate 2054 is provided at the lower end of the output shaft of the rotary motor 2052. L-shaped support plates 2055 are provided on both sides of the base 2051 to support the edges of the circular plate 2054, thereby reducing the load on the rotary motor 2052. A base frame 2053 is provided on the lower surface of the circular plate 2054. Multiple support feet 207 are installed between the base frame 2053 and the catalytic ring 204. The support feet 207 support the catalytic ring 204, and the rotation of the adjusting gear ring 2083 does not conflict with the support feet 207.

[0024] In this embodiment, preferably, the sediment removal component 206 installed on the upper surface of the catalytic ring 204 and used for collecting wastewater sediment includes: A mounting bracket 2061 is inclinedly set on the side of the support leg 207. A drive cylinder component 2062 is set at the outer end of the mounting bracket 2061. The drive cylinder component 2062 includes a shell and an internal drive cylinder. The shell seals and waterproofs the internal drive cylinder. A bellows is fitted on the piston rod inside the drive cylinder. This does not affect the extension and retraction of the piston rod, nor does it allow wastewater to enter the drive cylinder through the piston rod. A stabilizing block is set at the outer end of the piston rod. The two ends of the bellows are fixed between the stabilizing block and the shell, respectively. The stabilizing block is rotatably connected to the top of the upper mounting base 2063, which does not affect the angle change of the sedimentation collection net 2066. An upper mounting seat 2063 is installed at the lower end of the drive cylinder component 2062, and a lower mounting seat 2064 is provided on the upper surface of the catalytic ring 204; Two sets of rotating rods 2065 are rotatably installed between the upper mounting base 2063 and the lower mounting base 2064. Each rotating rod 2065 includes two rotating plates. The inner ends of the two rotating plates are rotatably connected, while the outer ends of the two rotating plates are rotatably connected to the upper mounting base 2063 and the lower mounting base 2064, respectively. The inner surfaces of the two rotating plates are provided with arc-shaped spring pieces 2067. When the rotating rods 2065 are tightened, they present a state similar to a straight line. The arc-shaped spring pieces 2067 on the inner side of the rotating rods 2065 abut against each other. The subsequent reset of the arc-shaped spring pieces 2067 facilitates the outward rotation of the rotating rods 2065. The two sets of rotating rods 2065 are rhomboid in shape, and the opening of the sedimentation collection screen 2066 is opened. And a sedimentation collection net 2066 installed on the inner surface of the two sets of rotating rods 2065.

[0025] In summary, during use, the drive component 202 operates, causing the connecting shaft 2015 to rotate, which in turn causes the cam 2012 and its slider 2013 to rotate. The slider 2013 slides in the oblong hole, thereby causing the upper sliding plate 2011 to rotate. When the upper sliding plate 2011 deflects to the right, the catalytic ring 204 below the base 2051 deflects to the left because the base 2051 is rotatably connected to the crossbeam 301. At this time, the piston rod inside the drive cylinder 2062 on the left extends, causing the upper mounting seat 2063 to move downwards and closer to the lower mounting seat 2064. The two rotating rods 2065 on the left side... When the catalyst ring 204 deflects to the left, the left side of the sediment collection net 2066 opens, and as it deflects to the left, it collects the precipitated products against the wastewater in the oxidation reaction tank 100. Meanwhile, the piston rod inside the right drive cylinder 2062 retracts, and the distance between the upper mounting seat 2063 and the lower mounting seat 2064 on the right side is at its maximum. The two sets of rotating rods 2065 on the right side are in a straight line, and the opening of the sediment collection net 2066 tightens, preventing the precipitated products from detaching during the swing. When the catalyst ring 204 deflects to the right, the opening of the left side of the sediment collection net 2066... During the collection process, the precipitate collection net 2066 on the right side opens. As the catalytic ring 204 swings left and right, it expands the contact area with the wastewater and collects the precipitate products from the oxidation process. Combined with the lifting component 400, this further expands the oxidation treatment area. When the catalytic ring 204 rotates, the rotary motor 2052 operates, driving the base frame 2053 and support legs 207 to rotate, which in turn rotates the catalytic ring 204. The adjusting component 208 changes the angle of the precipitate collection net 2066 opening, ensuring that the opening faces the direction of rotation of the catalytic ring 204. As the precipitated products in the oxidation reaction tank 100 are collected, the precipitated products in the oxidation reaction tank 100 are less likely to encapsulate the solid catalyst. The agitation method of the catalytic ring 204 on the wastewater can be a combination of lifting component 400 and swing arm component 201, or a combination of rotating component 205 and lifting component 400, or a combination of lifting component 400 and swing arm component 201. Multiple agitation methods for the wastewater can improve the contact reaction range between the catalyst and the wastewater. Similarly, the collection method of the precipitated products can also be freely combined to increase the oxidation treatment efficiency and stability of the wastewater in the oxidation reaction tank 100. Example 2

[0026] Reference Figure 7 This is the second embodiment of the present invention.

[0027] In this embodiment, preferably, the upper surface of the catalytic ring 204 is provided with an adjusting member 208 for driving the desquamation member 206 to rotate. By providing the adjusting member 208, the angle of the desquamation member 206 can be changed, which facilitates the subsequent rotation of the desquamation member 206 with the catalytic ring 204, expands the collection of wastewater precipitates, avoids the situation where precipitates remain in the tank and encapsulate the catalyst, increases the convenience of wastewater oxidation treatment, and improves the efficiency and stability of wastewater oxidation treatment. The desquamation member 206 collects the precipitates in the wastewater of the oxidation reaction tank 100 as it swings. Simultaneously, the adjusting member 208 is used to control the angle of the desquamation member 206. The adjusting member 208 includes: The adjusting toothed ring 2083 is located on the outside of the multiple set of sediment removal components 206. The lower surface of the lower mounting base 2064 is provided with a support rod 2081. The support rod 2081 includes an inclined end and a vertical end. The vertical end is rotatably connected to the catalytic ring 204, while the inclined end is connected to the lower mounting base 2064. This facilitates the subsequent installation of the entire sediment removal component 206 at a slight tilt, which, in conjunction with the swing amplitude of the catalytic ring 204, facilitates the collection of wastewater sedimentation. A small gear 2082 is sleeved on the support rod 2081. The small gear 2082 is sleeved on the vertical end of the support rod 2081 and meshes with the inner side of the adjusting gear ring 2083. And a drive gear 2084 located inside the adjusting gear ring 2083 to drive its rotation.

[0028] In this embodiment, preferably, a motor housing 2085 is provided on the upper surface of the catalytic ring 204, a motor is provided inside the motor housing 2085, and a sealed bearing or the like is provided between the motor housing 2085 and the motor output shaft, which not only does not affect the connection between the output shaft and the drive gear 2084, but also plays a role in sealing and waterproofing. The output end of the motor housing 2085 is connected to the drive gear 2084.

[0029] In this embodiment, preferably, lifting components 400 are provided between the two sides of the oxidation reaction tank 100 and the two ends of the top frame 300. By combining the lifting components 400 with the top frame 300, the height of the catalytic precipitation removal mechanism 200 can be changed, expanding the contact range between the subsequent catalytic ring 204 and the wastewater inside the oxidation reaction tank 100. It also facilitates the upward movement of the subsequent precipitation removal component 206 to detach from the oxidation reaction tank 100, remove the collected precipitate, and reposition it in the tank for further precipitate collection. The lifting components 400 include: A side frame 402 is fixed to the side of the oxidation reaction tank 100, and a lifting cylinder 401 is installed inside the side frame 402. A horizontal plate is installed on the side of the oxidation reaction tank 100 to support the lifting cylinder 401. The upper end of the piston rod inside the lifting cylinder 401 is connected to the side of the top frame 300 to increase the installation strength of the lifting cylinder 401.

[0030] In summary, when it is necessary to change the angle of the sediment removal component 206 during use, the motor inside the motor housing 2085 can be activated. The output shaft drives the drive gear 2084 to rotate, and the adjusting gear ring 2083 meshing with it rotates. The adjusting gear ring 2083 meshes with the pinion 2082, driving the support rod 2081 to rotate, which in turn drives the lower mounting base 2064 and the rotating rod 2065 connected to it to rotate, thereby driving the sediment collection net 2066 to rotate and changing the tilt angle of the net opening. When the angle is appropriate, the motor inside the motor housing 2085 stops working, and the angle of the sediment collection net 2066 is fixed. As the subsequent catalytic ring 204 rotates, the net opening faces the direction of rotation and sweeps across the wastewater to collect the sediment in the wastewater. The sediment remains at the bottom of the sediment collection net 2066. In conjunction with the lifting component 400, the collection range of wastewater sediment can be expanded, increasing the convenience of wastewater sediment collection and reducing the impact of sediment retention on wastewater oxidation treatment. Example 3

[0031] Reference Figure 8 This is the third embodiment of the present invention.

[0032] In this embodiment, preferably, an inlet pipe 101 is provided on the rear surface of the oxidation reaction tank 100, and a circulating preheating component 500 is provided between the inlet pipe 101 and the oxidation reaction tank 100. By providing the circulating preheating component 500, the wastewater entering the oxidation reaction tank 100 can be preheated, reducing the temperature difference between the newly entered wastewater and the wastewater in the tank, thus preventing the low-temperature wastewater from inhibiting the oxidation reaction. At the same time, the preheated wastewater temperature is reduced and it is circulated back into the tank, cooling the wastewater in the tank and reducing the negative impact of the high temperature of the wastewater in the tank. The circulating preheating component 500 includes: An annular preheating pipe 502 is sleeved on the water inlet pipe 101. The annular preheating pipe 502 is spiral-shaped, which facilitates uniformly surrounding the water inlet pipe 101. One end of the annular preheating pipe 502 is connected to the rear surface of the oxidation reaction tank 100, and the other end of the annular preheating pipe 502 is connected to the suction cylinder 503. A suction cylinder 503 is vertically installed on the rear side of the oxidation reaction tank 100. A pusher cylinder 505 is provided at the bottom of the suction cylinder 503. The piston rod inside the pusher cylinder 505 passes through the suction cylinder 503 and is fixed to the lower surface of the piston plate 504. The piston plate 504 is not affected by the temperature of the wastewater. The piston plate 504 is located inside the suction cylinder 503. A cooling plate 506 is provided on the upper surface of the piston plate 504. The cooling plate 506 is a semiconductor plate with its cooling surface facing upward, which facilitates contact with the wastewater entering the suction cylinder 503. It can cool the wastewater and alleviate the high temperature generated by the exothermic reaction of the wastewater oxidation process. And a suction pipe 501 installed between the suction cylinder 503 and the oxidation reaction tank 100.

[0033] In this embodiment, preferably, a one-way valve is provided on the body of the annular preheating pipe 502 near the suction cylinder 503, and a one-way valve is provided on the suction pipe 501. That is, when the piston plate 504 inside the suction cylinder 503 moves downward to suction, the one-way valve on the suction pipe 501 closes, while the one-way valve on the annular preheating pipe 502 opens. Conversely, when the wastewater inside the suction cylinder 503 is discharged into the oxidation reaction tank 100, the one-way valve on the suction pipe 501 opens, while the one-way valve on the annular preheating pipe 502 closes, which facilitates the entry and exit of wastewater into and out of the suction cylinder 503.

[0034] In this embodiment, preferably, a catalytic arc rod 2041 is provided on the lower surface of the catalytic ring 204. Both the catalytic arc rod 2041 and the catalytic ring 204 are filled with solid catalysts. The solid catalysts include, but are not limited to, iron(III) oxide, and are selected according to the actual wastewater treatment. Small holes are uniformly opened on the surfaces of the catalytic arc rod 2041 and the catalytic ring 204 to facilitate the reaction between wastewater and solid catalysts.

[0035] In summary, during operation, the wastewater inside the oxidation reaction tank 100 reacts with the solid catalyst in the catalytic ring 204, causing the wastewater temperature to rise. At this time, the pusher cylinder 505 operates, and the internal piston rod retracts, driving the piston plate 504 and the cooling plate 506 downwards. The space above the piston plate 504 increases, drawing the wastewater from the oxidation reaction tank 100 into the space above the suction cylinder 503. The wastewater in the tank, being at a higher temperature, enters the annular preheating pipe 502, where the temperature is transferred to the annular preheating pipe 502 and then to the inlet pipe 101. The wastewater inside 101 is preheated, and the temperature of the preheated wastewater is relatively lower. It then enters the suction cylinder 503 and comes into contact with the cooling surface of the cooling plate 506 for further cooling. The wastewater is then transported back to the oxidation reaction tank 100. The temperature of the relatively cooled wastewater is lower than that of the wastewater in the tank, but higher than that of the wastewater in the inlet pipe 101. The temperature difference will not be large when it enters the tank, thus relatively cooling the wastewater in the tank, reducing the impact of high temperature, increasing the oxidation efficiency of the wastewater in the oxidation reaction tank 100, and preventing the inhibition of the oxidation reaction caused by a large temperature difference, thereby improving the wastewater oxidation treatment efficiency. Example 4

[0036] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0037] In use, the driving component 202 can drive the swing arm component 201 to swing, which in turn drives the catalytic ring 204 to swing, expanding the contact reaction range with the wastewater. In conjunction with the sediment removal component 206, the retention of precipitated products in the wastewater is reduced. The collection angle of the sediment removal component 206 can be changed by the adjusting component 208. In conjunction with the lifting component 400, the oxidation contact range and the collection range of precipitated products in the wastewater are expanded. During the wastewater oxidation treatment process, the circulating preheating component 500 is used to preheat the newly entered wastewater, reducing the temperature difference. At the same time, it relatively cools down the high-temperature wastewater in the pool, reducing the adverse effects of high temperature, increasing the stability of wastewater oxidation treatment, and improving oxidation treatment efficiency.

[0038] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
