DETAILED DESCRIPTION

[0018] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0020] Example 1

[0021] like Figure 1-Figure 2 As shown, this embodiment provides an oxidation reactor, including a tank body 1, an inlet and exhaust pipe 2 and a holding box 5, the inlet and exhaust pipe 2 enters the tank body 1, the inner end of the inlet and exhaust pipe 2 is closed, a plurality of exhaust pipes 3 are connected to the inlet and exhaust pipe 2, the exhaust pipe 3 is vertically arranged, an exhaust pipe 4 is rotatably arranged on the exhaust pipe 3, the top of the exhaust pipe 4 is connected to a fixed block 12, a channel group is arranged in the fixed block 12, the outlet end of the channel group is located on the top wall of the fixed block 12, the exhaust pipe 4 is connected to a connecting pipe 13, the top of the connecting pipe 13 is connected to the inlet end of the channel group, a first gear 14 is provided on the exhaust pipe 4, each first gear 14 is meshed with another first gear 14, a motor 16 is provided in the tank body 1, the motor 16 is connected to a second gear 15, and the second gear 15 is meshed with one of the first gears 14,

[0022] The receiving box 5 is arranged in the tank body 1, and a liquid storage tank 6 is arranged in the receiving box 5. The liquid inlet pipe 7 passes through the tank body 1 and the receiving box 5 and enters the liquid storage tank 6. The side wall of the liquid storage tank 6 is provided with multiple drainage holes 8, and the multiple drainage holes 8 are at the same horizontal height. The drainage holes 8 are connected to a drainage pipe 9, and the bottom end of the drainage pipe 9 is located above the fixed block 12. The drainage pipe 9 corresponds to the fixed block 12 one by one. The drainage pipe 9 is connected to a fixed plate 10, and the fixed plate 10 is connected to an annular plate 11. The fixed block 12 is located in the annular plate 11.

[0023] The specific working principle is as follows: the exhaust gas enters from the exhaust gas inlet pipe 2, then enters multiple exhaust gas outlet pipes 3 respectively, and then enters the exhaust gas exhaust pipe 4. At the same time, liquid oxidant is continuously pumped into the liquid storage tank 6 from the outside through the liquid inlet pipe 7. After the liquid oxidant reaches the position of the drainage hole 8, it is discharged from multiple drainage holes 8 respectively, and then discharged through the drainage pipe 9 and falls into the fixed block 12. The motor 16 drives the second gear 15 to rotate, and then drives all the first gears 14 to rotate. The rotation of the first gear 14 drives the exhaust gas pipe 4 to rotate, and then drives the fixed block 12 to rotate. The liquid oxidant falling on the fixed block 12 is subjected to the centrifugal force of the rotation of the fixed block 12, and is thrown on the annular plate 11 to collide to form liquid droplets. At the same time, the exhaust gas enters the channel group through the connecting pipe 13, and is then discharged from the outlet end of the channel group. The exhaust gas and the liquid droplets formed by the collision on the annular plate 11 are fully contacted and oxidized, thereby realizing the spray oxidation treatment of the exhaust gas.

[0024] In this embodiment, the exhaust gas is diverted into multiple streams for separate oxidation treatment, so that the exhaust gas can fully contact with the liquid oxidant and the oxidation reaction is sufficient. In addition, the exhaust gas discharged from each exhaust pipe 4 corresponds to the liquid oxidant discharged from the liquid discharge pipe 9, so that the exhaust gas can fully receive the spray, reducing the escape of the exhaust gas without spraying. The liquid oxidant only needs to be pumped into the multiple liquid discharge pipes 9. The structure is simple and the operation is simple. The liquid oxidant collides on the annular plate 11 to form liquid droplets, which only requires the motor 16 to work. A large atomizer is not needed, reducing production and use costs. In this way, the structure in this embodiment can ensure the oxidation treatment effect of the exhaust gas while reducing production and use costs.

[0025] In this embodiment, the upper end of the liquid storage tank 6 is open, and an air inlet pipe 17 passes through the top wall of the tank body 1 and the top wall of the receiving box 5 and enters the receiving box 5. The liquid oxidant is discharged through the drain pipe 9. Since the liquid oxidant does not completely fill the drain hole 8 when it is discharged from the drain hole 8, nor does the liquid oxidant completely fill the drain pipe 9, some exhaust gas will enter the liquid storage tank 6 through the drain pipe 9 and the drain hole 8, where it reacts with the liquid oxidant to form solid precipitates. In this embodiment, air is pumped in through the air inlet pipe 17 and discharged through the drain pipe 9. The air fills the drain pipe 9 and is discharged, preventing exhaust gas from entering the liquid storage tank 6 through the drain pipe 9.

[0026] Example 2

[0027] This embodiment is further limited on the basis of Example 1. In this embodiment, the channel group includes a first channel 18 and a second channel 19. A cavity 20 is provided in the fixed block 12. The top of the first channel 18 is located on the top wall of the fixed block 12, and the bottom end of the first channel 18 is located on the side wall of the cavity 20. The inlet end of the second channel 19 is located on the bottom wall of the fixed block 12, and the outlet end of the second channel 19 is connected to the first channel 18. The position of the top of the second channel 19 is higher than the position of the outlet end of the second channel 19, and the connecting pipe 13 is connected to the inlet end of the second channel 19.

[0028] Specifically, in this embodiment, the inlet end of the second channel 19 is the inlet end of the channel group, and the top end of the first channel 18 is the outlet end of the channel group.

[0029] In this embodiment, in the direction from the outlet end of the second channel 19 to the inlet end of the second channel 19 , the second channel 19 first inclines upward and then inclines downward.

[0030] In this embodiment, the top of the cavity 20 is provided with a through hole, a sealing plate 21 is provided in the through hole, a spring 22 is connected between the sealing plate 21 and the bottom wall of the cavity 20, a drainage hole 23 is provided on the bottom wall of the cavity 20, a bottom plate 24 is located below the fixed block 12, the bottom plate 24 closes the drainage hole 23, the bottom plate 24 is connected to the sealing plate 21 by a connecting rod 25, and there is a gap between the connecting rod 25 and the side wall of the drainage hole 23, the drainage pipe 9 is divided into an upper tube 91 and a lower tube 92, and the lower tube 92 is slidably connected to the upper tube 91 Then, the lower tube 92 is movable and passes through the bottom wall of the storage box 5. Multiple lower tubes 92 are connected by a connecting plate 26. A lifting device 27 is provided on the bottom wall of the storage box 5. The output end of the lifting device 27 is connected to the connecting plate 26. A side hole 28 is provided at the bottom of the side wall of the lower tube 92. The lifting device 27 can drive the connecting plate 26 to move downward and then drive the lower tube 92 to move downward. The lower tube 92 can contact the top wall of the sealing plate 21 and press the sealing plate 21 to move downward into the cavity 20, and the side hole 28 enters the cavity 20.

[0031] Since the outlet end of the channel group is located on the top wall of the fixed block 12, most of the liquid oxidant that falls on the fixed block 12 is thrown onto the annular plate 11 due to centrifugal force, but some of the liquid oxidant will enter the channel group and then enter the exhaust pipe 4 and the exhaust outlet pipe 3 through the connecting pipe 13. In this way, the liquid oxidant that enters the exhaust outlet pipe 3 will react with the exhaust gas in the exhaust outlet pipe 3 to generate solid matter, and the particulate matter in the exhaust gas will fall into the exhaust inlet pipe 2 after being wetted. Over time, the accumulation of solid matter will cause the exhaust inlet pipe 2 to be blocked.

[0032] In this embodiment, the channel group is divided into a first channel 18 and a second channel 19, and a cavity 20 is provided in the fixed block 12. The exhaust gas enters through the second channel 19 and is then discharged through the first channel 18. After part of the liquid oxidant enters through the top of the first channel 18, since the top position of the second channel 19 is higher than the position of the outlet end of the second channel 19, the liquid oxidant cannot flow into the connecting pipe 13 through the second channel 19, and then flow to the exhaust pipe 4 and the exhaust outlet pipe 3. The liquid oxidant entering the first channel 18 flows into the cavity 20, which can prevent the liquid oxidant from entering the exhaust outlet pipe 3 to react with the exhaust gas and wet the exhaust gas, causing the solid matter generated by the reaction and the wet particulate matter to fall and cause the exhaust pipe 2 to be blocked.

[0033] When the solid matter accumulated in the cavity 20 reaches a certain amount, the lifting device 27 is started, and the lifting device 27 drives the connecting plate 26 to move downward, and the connecting plate 26 drives the lower tube 92 to move downward, and the lower tube 92 contacts the top wall of the sealing plate 21, and pushes the sealing plate 21 to move downward into the cavity 20. At this time, the sealing plate 21 drives the connecting rod assembly 25 to move downward, and the connecting rod assembly 25 drives the bottom plate 24 to move downward, and the bottom plate 24 opens the drainage hole 23, and at this time the bottom end of the lower tube 92 enters the cavity 20. The bottom end of the lower tube 92 is closed by the sealing plate 21, and the liquid is discharged into the cavity 20 from the side hole 28 at the bottom of the side wall of the lower tube 92. The solid matter in the cavity 20 is flushed and fused and then discharged through the drainage hole 23, and the fixed objects accumulated in the cavity 20 are processed, thereby achieving the cleaning of the cavity 20. This process only requires the lifting device 27 to work. In this way, while solving the blockage of the exhaust pipe 2, it also solves the problem of accumulation of solid matter in the cavity 20. The operation is simple, and it only needs to start the lifting device 27 at regular intervals.

[0034] In this embodiment, the side wall of the tank body 1 is provided with an inspection hole, and an inspection door is installed at the inspection hole. In this embodiment, the inspection hole is provided to facilitate inspection and maintenance of the interior of the tank body 1.

[0035] In this embodiment, the top wall of the tank body 1 has a vent hole with an exhaust valve installed at the vent hole, and the bottom wall of the tank body 1 has a drain hole with a drain valve installed at the drain hole. The oxidized gas is discharged through the vent hole and enters the next stage of treatment. The solid matter generated after the oxidation treatment and particulate matter in the exhaust gas are humidified and fall into the tank body 1, and are subsequently discharged through the drain hole.

[0036] In this embodiment, the containing box 5 is made of heat-insulating material.
