Description

Technical Field

[0001] The present invention relates to the technical field of industrial wastewater treatment, and particularly to an industrial wastewater catalytic oxidation reactor. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process. It contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Since industrial wastewater often contains various toxic substances and pollutes the environment and poses a great harm to human health, corresponding purification measures need to be taken for disposal before it can be discharged.

[0003] In the prior art, when treating industrial wastewater by the oxidation method, ozone is introduced into the wastewater for oxidation reaction. However, the flow rate of the wastewater inside the treatment device is relatively fast. When ozone is introduced into the device for oxidation treatment, the contact time between ozone and the wastewater is short, thus reducing the treatment effect of ozone on the wastewater. Summary of the Invention

[0004] The purpose of the present invention is to solve the defect that the contact time between ozone and wastewater in the prior art is short, thus reducing the treatment effect of ozone on the wastewater, and to propose an industrial wastewater catalytic oxidation reactor.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme: Design an industrial wastewater catalytic oxidation reactor, including a housing. A first partition is fixedly connected to the upper end inside the housing. A first gap is formed between the bottom end of the first partition and the bottom end of the housing. A second partition is fixedly connected to the bottom end inside the housing. A second gap is formed between the upper end of the second partition and the upper end inside the housing. The first partition and the second partition divide the housing into a first treatment chamber, a second treatment chamber and a third treatment chamber. An ozone generator is fixedly connected to the upper end of the housing. The air outlet of the ozone generator is communicated with a fixed pipe. One end of the fixed pipe extends into the second treatment chamber. A plurality of exhaust pipes are communicated with the fixed pipe at equal intervals along the length direction. Each exhaust pipe is inclined downward. A plurality of first connecting rods are connected to the fixed pipe at equal intervals along the length direction. One end of each first connecting rod is fixedly connected with a flow retarder. A mesh cover with packing is connected inside the third treatment chamber.

[0006] Preferably, a number of separation mechanisms are connected to the upper edge of the first processing chamber at equal intervals along the length direction. The separation mechanism includes a fixed frame. One side of the fixed frame is fixedly connected to the first partition plate. The fixed frame is inclined downward. A filter screen is fixedly connected to the fixed frame. A through hole is formed in the first processing chamber. One side of the fixed frame passes through the through hole and is fixedly connected to an open frame. The open frame is matched with the through hole. A sealing plate is fixedly connected to the open frame.

[0007] Preferably, the filter screen is an activated carbon filter screen.

[0008] Preferably, a flow-attenuating mechanism is fixedly connected to the upper end of the first processing chamber. The flow-attenuating mechanism includes a first guiding plate. The first guiding plate is fixedly connected to the first processing chamber. The first guiding plate is inclined downward toward the first partition plate. A second guiding plate is fixedly connected to the first partition plate. The second guiding plate is located below the first guiding plate. The second guiding plate is inclined downward.

[0009] Preferably, a number of second connecting rods are connected to the bottom end of the first guiding plate at equal intervals along the length direction. One end of each second connecting rod is fixedly connected to the upper end of the second guiding plate.

Specific embodiments

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0016] Example 1: Refer to Figures 1-5, An industrial wastewater catalytic oxidation reactor, comprising a housing 1. At the upper end inside the housing 1, a first partition plate 2 is fixedly connected. A first gap 3 is formed between the bottom end of the first partition plate 2 and the bottom end of the housing 1. At the bottom end inside the housing 1, a second partition plate 4 is fixedly connected. A second gap 5 is formed between the upper end of the second partition plate 4 and the upper end inside the housing 1. The first partition plate 2 and the second partition plate 4 divide the housing 1 into a first treatment chamber, a second treatment chamber and a third treatment chamber. At the upper end on one side of the first treatment chamber, a water inlet pipe is communicated. At the bottom end on one side of the third treatment chamber, a discharge pipe is communicated. At the upper end of the housing 1, an ozone generator 6 is fixedly connected. The air outlet of the ozone generator 6 is communicated with a fixed pipe 7. One end of the fixed pipe 7 extends into the second treatment chamber. Along the length direction of the fixed pipe 7, a number of exhaust pipes 8 are equidistantly communicated. Each exhaust pipe 8 is arranged obliquely downward. Along the length direction of the fixed pipe 7, a number of first connecting rods 9 are connected at equal intervals. One end of each first connecting rod 9 is fixedly connected with a flow buffering plate 10. Inside the third treatment chamber, a wire mesh cover 11 with packing is connected.

[0017] Working process: Industrial wastewater is introduced into the first treatment chamber through the water inlet pipe. The wastewater in the first treatment chamber slowly enters the second treatment chamber through the first gap 3. As the industrial wastewater continues to be introduced, the liquid level of the wastewater in the second treatment chamber gradually rises. After the liquid level in the second treatment chamber rises to a certain height, it is introduced into the third treatment chamber through the second gap 5. The industrial wastewater falls on the wire mesh cover 11 with packing. The industrial wastewater slowly passes through the wire mesh cover 11 with packing. The wire mesh cover 11 with packing filters the wastewater. The wastewater in the third treatment chamber is discharged from the discharge pipe. When treating industrial wastewater, the ozone generator 6 is powered on and started. After the ozone generator 6 starts, ozone is generated. The generated ozone is introduced into the fixed pipe 7. The ozone in the fixed pipe 7 is released from the exhaust pipes 8. The released ozone flows downward, and the industrial wastewater in the second treatment chamber moves upward. Convective collision occurs between the ozone and the industrial wastewater, prolonging the contact time between the ozone and the industrial wastewater, improving the treatment effect of the ozone on the industrial wastewater. At the same time, when the industrial wastewater moves upward, it contacts the flow buffering plate 10. The flow buffering plate 10 buffers and decelerates the industrial wastewater, prolonging the contact time between the industrial wastewater and the ozone, thereby improving the treatment effect on the industrial wastewater.

[0018] Example 2: After the industrial wastewater is introduced into the housing 1, there are particulate impurities in the industrial wastewater. The particulate impurities adhere to the flow buffering plate 10, thereby reducing the treatment effect of the industrial sewage. Refer to Figure 2 、 Figure 4 And Figure 6, as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a plurality of separation mechanisms 12 are connected to the upper edge of the first treatment chamber at equal intervals along the length direction. The separation mechanism 12 includes a fixed frame 121. One side of the fixed frame 121 is fixedly connected to the first partition plate 2. The fixed frame 121 is inclined downward. A filter net 122 is fixedly connected to the fixed frame 121. The filter net 122 is an activated carbon filter net. A through hole is opened on the first treatment chamber. One side of the fixed frame 121 passes through the through hole and is fixedly connected with an open frame 123. The open frame 123 cooperates with the through hole. A sealing plate 124 is fixedly connected to the open frame 123. Industrial wastewater is introduced into the first treatment chamber through the water inlet pipe. The introduced sewage falls on the filter net 122. The filter net 122 filters the particulate impurities in the sewage. Since the fixed frame 121 is inclined downward, the particulate impurities on the filter net 122 roll along the inclined direction of the fixed frame 121. The filtered impurities fall into the open frame 123. The sealing plate 124 is removed to clean the impurities in the open frame 123, avoiding the particulate impurities from adhering to the flow retarder plate 10 and improving the treatment effect of industrial wastewater.

[0019] Embodiment 3: The wastewater falls on the filter net 122 and flows downward under its own gravity, continuously impacting the filter net 122, which easily causes damage to the filter net 122. Refer to Figure 2 And Figure 6 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a flow retardation mechanism 13 is fixedly connected to the upper end of the first treatment chamber. The flow retardation mechanism 13 includes a first guiding plate 131. The first guiding plate 131 is fixedly connected to the first treatment chamber. The first guiding plate 131 is inclined downward toward the first partition plate 2. A second guiding plate 133 is fixedly connected to the first partition plate 2. The second guiding plate 133 is located below the first guiding plate 131. The second guiding plate 133 is inclined downward. A plurality of second connecting rods 132 are connected to the bottom end of the first guiding plate 131 at equal intervals along the length direction. One end of each second connecting rod 132 is fixedly connected to the upper end of the second guiding plate 133. The introduced wastewater falls on the first guiding plate 131. The wastewater on the first guiding plate 131 falls on the second guiding plate 133. The second guiding plate 133 guides the wastewater, causing the wastewater to collide with the inner wall of the housing 1. The wastewater flows downward along the inner wall of the housing 1, reducing the impact on the filter net 122 and making the filter net 122 not easily damaged.

[0020] Embodiment 4: When the wastewater is treated by the mesh cover 11 with packing, the impurities in the wastewater accumulate at the upper end of the mesh cover 11 with packing, causing blockage at the upper end of the mesh cover 11 with packing, thus affecting the treatment of the wastewater. Refer to Figures 2-4, as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a slag removal mechanism 14 is connected to the housing 1. The slag removal mechanism 14 includes a mounting plate 141 which is fixedly connected to the housing 1. A motor 142 is fixedly connected to the mounting plate 141. The output end of the motor 142 extends into the third treatment chamber and is fixedly connected to a first stirring member 143. The first stirring member 143 is located above the mesh cover 11 with packing. One side of the third treatment chamber communicates with a slag discharge pipe 144. The slag discharge pipe 144 is located on one side above the mesh cover 11 with packing. After the motor 142 is powered on and starts, it drives the first stirring member 143 to rotate. After the first stirring member 143 rotates, it stirs the wastewater above the mesh cover 11 with packing. The slag discharge pipe 144 is opened, and the sundries above the mesh cover 11 with packing are released from the slag discharge pipe 144, avoiding the blockage of the sundries at the upper end of the mesh cover 11 with packing.

[0021] Embodiment 5: When treating wastewater, sundries in the wastewater accumulate at the bottom of the second treatment chamber. Refer to Figures 3-4 , as another preferred embodiment of the present invention, the difference from Embodiment 4 is that an anti-accumulation mechanism 15 is connected to the bottom of the second treatment chamber. The anti-accumulation mechanism 15 includes a second stirring member 151 which is rotatably connected to the housing 1. One end of the second stirring member 151 extends to the inner bottom of the second treatment chamber. The second stirring member 151 is connected to the output end of the motor 142 through a belt transmission member 152. The output end of the motor 142 drives the second stirring member 151 to rotate through the belt transmission member 152. After the second stirring member 151 rotates, it stirs the wastewater at the inner bottom of the second treatment chamber, enabling the sundries to flow with the wastewater and avoiding the accumulation of sundries at the bottom of the second treatment chamber.

[0022] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
